A peer-led physical activity intervention in schools for adolescent girls: a feasibility RCT.
Show detailsFormative research
Formative research was conducted in 2015. The sequencing of phase 1 is shown in Figure 2; it comprised:
- a focus group with the DECIPHer Advice Leading to Public Health Advancement (ALPHA) group (a research advisory group of young people) and an interview with a local secondary school teacher
- a series of iterative focus groups with Year 8 girls in the pilot study school
- sharing of practice and experience with the ASSIST+ FRANK51 team
- a review of the proposed intervention by the chief operating officer of IMPACT.
The pilot study was granted ethics approval from the School for Policy Studies, University of Bristol (SPSREC14–15.A10) and was sponsored by the University of Bristol.
A semistructured focus group was conducted with six adolescent girls (aged 13–16 years) from the DECIPHer ALPHA public and patient involvement (PPI) group. A female PE teacher from a local secondary school was also interviewed. The focus group and interview were audio-recorded and the data were analysed using deductive thematic analysis using the question topics as a guide.52 Table 1 shows the themes, summarised findings and the implications for the intervention design.
Recruitment and description of the pilot study school
One pilot school was identified by Wiltshire Council to be above the median of the Pupil Premium (i.e. relatively more deprived) and which would give a robust early test of the intervention. Recruitment materials were sent to the head teacher, who then delegated responsibility to a school contact (assistant leader in learning in PE). A school study agreement form was completed. The school (N = 1086, students; n = 70, Year 8 girls) was located in a medium-sized town. The school was given £500 as a thank you for participating.
Iterative focus groups: round 1
Methods
Two semistructured focus groups (n = 16 participants, eight per group; duration 61–66 minutes) were conducted by two facilitators in May 2015 to explore girls’ views on PA barriers, PS recruitment, logistics and content of PS training and use of social media. Focus groups were audio-recorded, transcribed verbatim and analysed using thematic analysis52 to generate themes pertaining to intervention design and refinement. All participants provided informed consent and were given a £5 voucher in recognition of their time.
Results
Findings are presented under two themes (Recruitment materials and Intervention content) alongside mapping in which the girls’ views were included in the intervention design.
Recruitment materials
Both focus groups suggested that PLAN-A recruitment materials should highlight how their participation in the project would (1) help their peers; (2) improve their own (and PS) skills and knowledge; and (3) increase their potential to influence their peers and have their voice heard. These themes should be reflected on the PLAN-A website and a video would be a good method of communication for girls their age. Both focus groups recommended that recruitment materials provided an insight into the PA training activities. Certificates, endorsements in records of achievement and/or PLAN-A-branded clothing were not viewed as suitable incentives to participate.
Intervention content
Barriers to, and facilitators of, being active
Well-being and feeling good about oneself were seen as key facilitators. Time constraints, lack of confidence, competence and being seen by boys when exercising were barriers.
Characteristics of peer supporters and trainers
The characteristics of a good PS included confidence, good communication and leadership skills and an ability to encourage others. Girls wanted confirmation at the point of peer nomination that the peers whom they nominate do not need to be their friends. The characteristics that participants thought the trainers should have included patience, fun, having good knowledge about PA and being genuine in their relationship with the girls.
Expectations of peer supporter training
Both groups recommended that games should not be too childish and suggested focusing on topics such as making PA fun, how to fit PA into their day, how much PA to do and how to be a PS. Participants also suggested including role-play, reaction test games and parachute games.
Concerns about being a peer supporter
Participants’ concerns about being a PS included peers not listening or disagreeing with what they said, not knowing what to say, being judged and teased.
These findings were used to refine the intervention content, including draft recruitment materials, PS training timetable and study logos, that were then further explored from the user’s perspective in the second round of focus groups.
Iterative focus groups: round 2
Methods
Participants were the same girls who had participated in round 1. A topic guide was developed to explore girls’ preferences for the study logo, feedback on recruitment materials, the PS training timetable, how best to communicate with PSs (e.g. using e-mails), how to make training fun and engaging, and dealing with potential bullying. Focus groups were between 40 and 42 minutes in duration, they were audio-recorded, transcribed verbatim and analysed thematically, as in round 1. Participants were each given a £5 voucher.
Results
The findings are similarly organised into Recruitment materials and Intervention content themes.
Recruitment materials
Suggested revisions to the recruitment materials included having less text and more pictures, emphasising the fun side and benefits of the training, giving further details of what the PS training would entail and reiterating that PSs did not have to be good at sport. Participants selected a favourite logo and guided the colour and the tag line ‘peer-power active girls’.
Intervention content
Draft training timetable
Incorporating yoga was a considered a good idea, but the word ‘yoga’ may be off-putting to some. Key points for creating a fun atmosphere included a non-serious environment, playing music at times and preventing individuals from dominating discussions.
Peer supporter training activities
Participants suggested bean bag games and further creative tasks, such as poster-making. Although participants from both groups thought the term ‘energiser’ was appropriate for activities to refresh the group, one group suggested the term ‘circle time’ was childish. Participants had concerns about PSs receiving support via e-mail, including being e-mailed by ‘strangers’.
Social media/communication
Participants were asked about receiving e-mails to remind them of the PS role. Platforms such as Facebook were popular but pupils reported that its use was not permitted within school, thus preventing a school-based project from endorsing its use. The idea of contact via short messaging service (SMS) text was not raised by the students, but was supported when prompted. However, some participants raised concerns about sharing their personal mobile number with the research team and being contacted by ‘strangers’ (i.e. members of the PLAN-A team/trainers). Students also demonstrated inconsistent use of school e-mail, with some not using it and others checking it only in information technology lessons. A common theme for e-mail and social media contact was that participants did not want to be contacted too frequently (e.g. every few weeks was suggested as suitable).
Summary
Phase 1 resulted in the co-production of the draft PLAN-A, which was taken forward to pilot testing. The ASSIST intervention framework was successfully blended with the views and preferences of the user group. A description of how these findings were incorporated in to the final intervention is presented in Appendix 1.
Pilot study
Aims and objectives
The objective of the pilot study was to test the student recruitment approach and rehearse the peer nomination and PS selection processes, train the trainers and test the PS training (see Chapter 2, Description of the final intervention elements for details). In evaluating the delivery and receipt of the pilot intervention to identify refinements, the process evaluation methods were also piloted.
Methods
School and participant recruitment
Recruitment of the pilot school is presented in Recruitment and description of the pilot study school. A recruitment briefing was given to all Year 8 girls (N = 70; a new Year 8 cohort not involved in the formative work) to introduce PLAN-A and explain the role of the pilot school. Students were invited to ask questions and received parent and child information packs (distributed to absent girls by the school contact). Parents signed an opt-out form if they did not wish their child to participate. Parents of PSs provided written informed consent for their daughters to attend the training and PSs provided assent.
Peer supporter nomination, selection and recruitment
All consenting students completed a peer nomination questionnaire. The analysis of peer nomination questionnaires and the selection of PSs was carried out in accordance with the PLAN-A peer nomination standard operating procedure (SOP). This mirrored the ASSIST process: the 18% of students who received the most nominations were selected, with the aim of 15% of the year group being trained as PSs. Commensurate with ASSIST protocols, in which the cut-off point of 18% included multiple students, all of these students were invited to be a PS. Students who were selected to be a PS were invited to a meeting held within school that outlined what the nomination meant, the PS role and training. Students were provided with written information for themselves and their parents and were asked to provide written assent and parent consent to participate as a PS.
Trainer recruitment
A list of trainers was generated through local contacts and searches of sports development, youth work and health promotion organisations near to the pilot school. Two trainers were recruited to deliver the pilot PS training. In line with ASSIST28 and the AHEAD study,40 trainers were recruited to have between them a combination of subject (PA/health promotion) expertise and experience in teaching or leading groups of adolescents (e.g. theatre and/or youth work experience). Both trainers met informally with the principal investigator and project manager, who explained the study and informally assessed the trainers’ fit with the role.
Pilot train the trainers course
The two trainers received a 3-day training course, covering all aspects of the study (see Description of final intervention elements for a full description of the course). The training was provided by three study staff (MJE, KB and JM).
Pilot peer supporter training
The 2-day PS training was piloted in a venue close to the school site (see Description of final intervention elements). Following the training, PSs were asked to support their peers in school, as instructed in the training, for 5 weeks. This time was deemed sufficient for the girls to experience the PS role and to identify any challenges associated with it. Given the short time frame between the pilot study and the delivery of the intervention in the feasibility study, the top-up PS training was not included in the pilot.
Quantitative measures
Participant recruitment and retention
The number and percentage of participants who opted out of the study was recorded in addition to the number of girls attending peer nomination, the number of girls invited to be a PS and the percentage of girls who consented.
Peer supporter training attendance and adverse events
Trainers recorded the attendance of girls at each day of the PS training and reasons for absence. Trainers recorded adverse events and reported them to the research team.
Trainer questionnaire
Trainers completed an evaluation questionnaire following delivery of the PS training (see Appendix 2). The measures were adapted from a similar questionnaire used in the AHEAD study.40 Achievement of PS training objectives was assessed through trainers’ perceptions that the training achieved key objectives of increasing PS knowledge, interpersonal skills, communication skills and confidence to be a PS using a four-point scale (0 = ‘not well at all’ to 3 = ‘very well’). Perception of the PS response to training was measured using four items (engagement, involvement, enjoyment and interest) and scored from 0 (‘not at all’) to 3 (‘very’). The training arrangements (e.g. suitability of training space) were rated on a five-point scale (0 = ‘poor’ to 4 = ‘excellent’).
Peer supporter questionnaire
Peer supporters completed an evaluation questionnaire at the end of the training (see Appendix 3) that assessed enjoyment, views on training content and logistics and perceived trainer autonomy support. Enjoyment of the training was rated using a five-point scale (1 = ‘not at all’ to 5 = ‘a lot’) and open text responses. Ten items assessed PSs’ views on the content and logistics of the training (e.g. ‘I understand my role as a PS’, ‘the length of the training was about right’) using a scale ranging from 0 (‘disagree a lot’) to 4 (‘agree a lot’). The Sport Climate Questionnaire53 measured PSs’ perceptions that trainers were autonomy supportive with five items (e.g. the PLAN-A trainers provided me with choices and options) anchored by responses ranging from 0 (‘disagree a lot’) to 4 (‘agree a lot’). The mean of the five items was derived to produce an autonomy support score for each training pair.
Observation of the pilot peer supporter training
A researcher who worked on the AHEAD study, and was familiar with the PS training approach, observed the PS training to assess fidelity. An observation form (see Appendix 4) was developed to record the timing of training components and to record whether or not individual activity objectives were met (0 = objective fulfilled ‘not at all’ to 3 = objective fulfilled ‘lots’). PS engagement was estimated from 0 (‘not at all’) to 3 (‘very’) for each activity. Notes documenting the extent to which trainers’ delivery style was need-supportive, elements that worked and those that did not were made.
Qualitative measures
Peer supporter focus groups
Focus groups with PSs (n = 10) were conducted at two time points: (1) the day after the second day of PS training (‘post training’) and (2) approximately 5 weeks after training (‘during intervention’). At both time points, PSs were divided into two groups of five. The post-training focus group guide focused on identifying improvements and participants’ experiences of the training and views on trainers. The during-intervention focus group guide examined the girls’ experiences of being a PS, feelings of preparedness, what actions they had taken, what had/had not worked and what their Year 8 peers thought of their role. Focus groups ranged from 25 to 30 minutes in duration.
Trainer interviews
Both trainers were interviewed separately (interview lengths were 63 and 52 minutes) by Kathryn Banfield. The trainer interview guide considered both the train the trainers workshop and the delivery of the PS training, including the content and logistics of training, what worked/what did not, potential changes and how to engage the PSs. Interviews and focus groups were recorded using an encrypted digital recorder (Olympus DS-3500; Olympus, KeyMed House, Southend-on-Sea, UK), then transcribed verbatim and anonymised.
Quantitative analysis
Quantitative data were analysed descriptively using means and SDs for each trainer or number and per cent of participants, as appropriate. Data from open-ended questions on the PS evaluation forms (e.g. ‘to make the training better you could . . .’) were reduced to qualitatively similar categories and a frequency count was derived.
Qualitative analysis
The framework method54 was used to produce a matrix for constant comparison to synthesise the data from the PSs and the trainers. This method facilitates the combination of inductive and deductive analysis. Data were analysed using the following steps:
- Kathryn Banfield, Mark J Edwards and Joe Matthews read and re-read each transcript and listened to audio-recordings to become familiar with and write initial impressions of the data.
- Initial codes for each informant group were created. For the purposes of deductive analysis, predefined codes were broad (Table 2). In addition, codes were inductively developed by the three researchers independently. To ensure consistency and agreement, each researcher independently coded the same transcript from each informant group.
- The three researchers discussed the codes and agreed a refined set of codes that could be applied to the remaining transcript(s). An analytical framework was developed for PSs and trainers.
- Each framework was applied to the remaining transcripts by the three researchers (KB, MJE and JM) using NVivo (version 10; QSR International, Warrington, UK). Each researcher applied the framework to a different set of transcripts (trainer, post-training and during-intervention focus groups) and this was cross-checked by another researcher to ensure consistency and agreement of coding. New codes that emerged were discussed and amendments were made to each framework.
- Coded data were charted into a framework matrix in NVivo to summarise the data for PSs and trainers by category, including representative quotations.
- Codes were interpreted and themes generated through frequent meetings to review the coding matrix. The three researchers (KB, MJE and JM) agreed on illustrative quotations.
The frameworks were triangulated between informant groups to assess convergence.
Qualitative notes collected by the observer were used as a reference point for intervention refinements only. Formal analysis was not conducted. The qualitative and quantitative findings were blended to provide a rich mixed-methods evaluation.
Results
Participant recruitment, peer nomination, peer supporter selection and recruitment
Participant recruitment flow is summarised in Figure 3. Of the 70 Year 8 girls, 54 (77%) attended the study briefing. Three (4%) study opt-out forms were returned. A total of 54 girls completed the peer nomination questionnaire, and the two researchers who led this process were satisfied that no amendments were required. The PS selection process was successful and 14 girls (20%) were invited to be a PS, all of whom attended the briefing meeting. The meeting was well received and 11 girls (16%) provided assent and parent consent to participate in the training.
When PSs reflected on the peer nomination process they commented that the majority of PSs were from the same friendship group (many from the netball team) and believed that most of their friends were physically active:
. . . a lot of the people chosen are from the same friend group anyway, so there’s a lot of different people in the school who won’t have any friends that will have been voted for . . .
Post-training focus group 1
One participant suggested that rewording the peer nomination form to refer to ‘their closest friends’ could increase the diversity nominations across friendship groups:
I think maybe if you’d got everybody to write down, I don’t know, their five closest friends, then you could have a person from every friendship group.
Post-training focus group 1
Reasons PSs gave for wanting to be a PS included wanting ‘to help me help more people’ and personal skill development:
. . . you could benefit a lot of skills, not just for use in school but for when you get older for your jobs and stuff like that.
Post-training focus group 1
One participant took part because she thought the course would be focused on playing sports:
I thought it was to do with sports, to be honest.
Post-training focus group 2
During the PS meeting, participants suggested that they would prefer to wear PE kit, which the school contact agreed with. For the feasibility study, a decision was taken to recommend that the girls wear comfortable, casual clothing so as to (1) highlight that the training is not a sports event, (2) avoid the potential negative connotations of PE or PE kit for some PSs and (3) separate the PLAN-A training from school.
Recruitment of trainers
Two female trainers were recruited and, as planned, shared a mixture of expertise in delivering PA/sports coaching to young people, and in theatre and youth work settings.
Train the trainers
Overall, the training was delivered according to plan with little deviation from the schedule. Key feedback from the trainers was to provide more active, hands-on activities early in the training, before agreeing the group rules.
Intervention materials
All training and intervention materials, including the session plans and trainers’ guide, were seen as useful and clear. One trainer felt that the session plans presented too much information for use in the training (see Chapter 2, Peer supporter training, Logistics and resources).
Structure and venue
Trainers felt that there was insufficient training time for them to understand the content of the activities and allow them to ‘sink in’ (Trainer 1) and that the training was carried out too far ahead of the PS training delivery. Both trainers suggested lengthening the training to allow more time to practise each activity rather than just talk through them. The venue was considered satisfactory, but too small:
I think you could have done more learning by practise, by doing, because then you actually fully understand what the exercise is and how it works and what you’re trying to get from it.
Trainer 1
The training was well received, with clear information delivered with sufficient depth. Trainer 2 felt that there could have been more detail on the background of the project that they could disseminate to PSs:
If you went through it [background information] a little bit more, I think when we then said it to the girls I think it might have flowed a lot better rather than just saying, ‘OK, that’s that.’ It might have been nice to go in depth.
Trainer 2
Feelings of preparedness
Both trainers felt insufficiently prepared to deliver the PS training based on the train the trainers event alone. One trainer revisited the content in their own time, the other wanted to but did not have time:
There maybe needs to be another couple of hours added on, to maybe 2 top-up days, just to really go through it . . . I don’t think I was prepared enough in terms of knowing each activity off by heart.
Trainer 2
In response to this, the week before delivery of the PS training, a half-day meeting was held to allow trainers to prepare. The trainers found the extra meeting useful and the timing, structure and content of the 3-day train the trainers event was revised in light of these findings.
Peer supporter training
Attendance
Attendance was 91% (n = 10) at both training days; one girl did not attend because of a disagreement with another PS outside the PLAN-A training.
Logistics and resources
The PS training space and venue were rated ‘adequate’ by both trainers (Figure 4) and PSs (see Figure 7). This was largely because of its small size and lack of break-out space. This led to an environment in which it was difficult to concentrate. The observer also felt that the layout of the room (including a lack of tables) led to a very informal learning environment. Trainers and PSs rated the refreshments for the training highly (see Figures 4 and 7).
The training manual and resources were considered to be ‘very good’ and ‘good’, respectively, by the trainers (see Figure 4). Trainers agreed that the session plans were helpful and clear, but suggested condensing the quantity of information to make delivery easier:
There’s too much going on on the page . . . I don’t think you can take that in and use that as a thing to use in the classroom, for me.
Trainer 1
As a result, cue cards were developed that allowed the trainers to write their own notes about each activity to use in the PS training.
The girls found the PS booklets to be a helpful prompt of key information and good to show others what they did. They suggested that the booklet should be used more for reference by PSs rather than using it to write in during the training:
If you were to forget something, then you have a booklet to look back on. I feel maybe instead of copying it down you could have it written on the board and already written in the booklet.
Post-training focus group 2
The PSs felt that the PS diaries were a good idea; however, during the intervention the girls reported not using them because they forgot about them or did not want to record conversations:
I just don’t need it. I just can’t be bothered with it.
During-intervention focus group 2
Fidelity to the session plans
Given the time constraints, on day 1 two activities were not delivered: the ‘thought shower: why be active?’ (10 minutes in duration) and ‘post box’ (10 minutes in duration) activities. On day 2, the ‘relaxation activity’ (5 minutes in duration) was excluded.
The allocated time and observed delivery time for each activity are shown in Appendix 5. On day 1, three out of nine activities before lunch took more time than allocated to deliver (e.g. ‘what do we know already?’). Lunch was slightly longer than scheduled, which resulted in activities after lunch being excluded or shortened. On day 2, activities before and immediately after lunch were an average of 12 minutes longer than scheduled, again leading to activities in the afternoon being given less time. Qualitative findings supported the observations: trainers felt that there was too much content to deliver and a lack of time for discussion. As a result, both trainers suggested that the training should be extended and more time should be added for discussion:
It’s too much in 2 days . . . I think it would have been nice to spread it over 3 days if you keep the activities, have a bit longer for each of them.
Trainer 2
The observer recorded that trainers added in active games to energise girls when necessary. Despite intending to benefit the girls, these contributed to the drift from the schedule. In addition, the observer noted that trainers could have shortened some sessions that were longer than intended:
Too long was given for discussions amongst small groups/activities . . . The girls would then talk about ‘off task’ things . . . time could have been used better.
Observation note
The extent to which PS training objectives were met is reported in Table 3. For timetabled sessions that comprised more than one distinct activity, the mean objective fulfilment is reported. Seven activities (41.18%) across both days were not rated. The mean rating for activities was 3.00, suggesting that objectives were achieved. However, fulfilment of objectives was lower (1.00) for activities at the end of day 2.
Both trainers felt they successfully enhanced PSs’ knowledge about PA, communication skills, interpersonal skills and understanding of their PS role (Figure 5). The objective to enhance PSs’ confidence to spread informal messages among their peers was not met well (1.5 ± 0.71); this supports PSs’ reported low confidence in this area (see Peer supporters’ experience of training).
The qualitative data gave insight into why some objectives were not achieved fully, including losing focus because of activities over-running (and other activities being rushed), omitting key activities and trainers not being clear on general group rules:
When it came to the core message of it and becoming a PS, I think we did not do enough because we physically did not have enough time.
Trainer 2
Peer supporters’ experience of training
Peer supporters’ engagement with training was high on day 1 and slightly less so on day 2 (Table 4). A need to maintain engagement in the ‘communication skills’ and ‘finishing up’ activities was identified.
Figure 6 shows that the trainers felt the PSs were very involved throughout the training. They perceived the PSs to be somewhat engaged and interested. PSs wanted to discuss topics and ask questions throughout:
Every time we did something they wanted to talk about it. They were quite chatty and so they wanted to talk about things.
Trainer 1
That was quite good because you had to debate your point. That was quite good.
Post-training focus group 1
Girls were particularly engaged in activities that they could relate to and that involved being active:
It worked well because the video is so powerful. It was a ‘visual’ and some of them probably can relate to that . . . that’s why, because they can relate to those questions.
Trainer 2
However, although most activities were rated as highly engaging, there was evidence of some boredom, fatigue and distraction because of the ineffective timings of activities (i.e. rushing activities at the end of day 2), overuse of writing rather than more physical tasks and a disagreement between PSs on day 2:
Some silly[ness], some look bored [afternoon] day 2? Lethargic.
Observation notes
Some became distracted or I saw it in their face. OK, they might be looking but I could see they’re still not there.
Trainer 2
I just think there could have been more activities. . . . We probably learn more by doing stuff than writing because I think we get a bit bored writing.
Post-training focus group 1
Enjoyment over the 2-day training was moderate to high and was marginally higher on day 2 (3.80 ± 0.79) than on day 1 (3.30 ± 0.68). Open-ended responses revealed that all girls enjoyed the ‘listening train’ activity most and 60% felt they were good at role-play tasks. Activities that were more active and involved discussion and debate were also enjoyed, which supported trainers’ perceived drivers of engagement (see above):
I liked the big discussion we had about fitness between boys and girls and self-confidence. I liked that big debate.
Post-training focus group 2
Peer supporters believed that the training helped them understand their role; they enjoyed the games and learnt something new (Figure 7). Eighty per cent reported five different facts they learnt about PA in free text. The PSs felt prepared to support their friends by enhancing their knowledge, confidence and ability to empathise with others:
It does actually work, that you feel like you can go out and talk to people about it. It’s not just something that you do and then you forget about it.
Post-training focus group 1
Like, if one of your friends has an insecurity, you know how to understand them and how to talk to them about it.
Post-training focus group 1
Trainers expressed concerns about the PSs’ ability to be realistic about how to peer support. This was also reflected in observation notes that questioned how empowered the girls were to make changes at school. Similarly, 60% of PSs suggested that more time could be devoted to practising being a PS, which would further enhance their confidence to be a PS (see Figure 7). Some PSs were unsure of how to use the facts they had learnt or how to start a conversation with their peers:
It feels like if we have all these facts – like, you can’t just casually slip a fact into, like, a conversation that you’re having with someone.
During-intervention focus group 2
Peer supporters thought that including more activities that focus on building confidence would improve the training:
Respondent 1:
Like with the confidence, we didn’t go a lot over how to be confident.
Respondent 2:
Yeah, because that’s like a major thing. If you’re going to help someone else you need to be confident in yourself as well.
Post-training focus group 1
Need-supportiveness of trainers and perceptions of need-support
On average, PSs reported relatively high levels of trainer autonomy support (3.42 ± 0.47; range 2.80–4.00) and thought that trainers were helpful (3.80 ± 0.42) and friendly (4.00 ± 0.00). Similarly, the observation documented that the trainers circulated among the girls, interacted with them and helped them with their tasks. The girls respected the trainers, commenting that they were different from teachers, made the training fun, were trusted, not boring and ‘understood us more than actual teachers’:
If you said something to them, you really felt you could trust them. They were just very friendly and stuff.
Post-training focus group 2
Autonomy support
Trainers provided autonomy by giving PSs choice within a structure of clear instructions and the opportunity to lead discussions and express their opinions:
They gave us lots of choices. They kind of said what to do but then they were giving you choices of how to do it, which was better than everybody saying, ‘you’ve got to do it like this’.
Post-training focus group 1
Trainers empathised with the PSs, and when the training required concentration or when engagement was low, they responded by incorporating elements that they felt the girls enjoyed:
In the lunchtimes, they were desperate to move. We were getting the tennis balls out and [Trainer 2] got some tunes on and was getting them dancing.
Trainer 1
Competence support
Trainers frequently provided competence-based feedback, praising the girls’ efforts. Trainers circulated around the group asking questions and they provided help when needed. Both trainers reinforced the girls’ understanding of activities and provided them with the skills to become a PS, in particular ensuring that the girls were realistic about their role:
We talked a lot about being realistic. You’ve got to be realistic, so it’s not saying, ‘Right, let’s go for a 2-hour run.’ ‘Oh, but I don’t like running.’ Where do you go from there? ‘I want to watch TV.’ ‘Let’s go for a half-hour walk and then come and watch TV.’ So it’s that compromise . . .
Trainer 1
Trainers explicitly tried to help the PSs understand their role and spent time empowering the girls’ confidence to be a PS:
I think if they feel confident and empowered then they can go off and do anything. And I know that was quite a big part of the course, and I think we spent a lot of time doing that and I hope and think that went in.
Trainer 1
PSs, competence may have been undermined when the trainers rushed activities. Sometimes the PSs felt confused, and trainer 2 felt that some core messages were missed because of time constraints:
When it actually came to the core message of it and becoming a PS, I think we didn’t do enough of because we physically didn’t have enough time.
Trainer 2
Relatedness support
Both trainers endeavoured to, and were successful in, forming trusting relations with the PSs within the short training window. Trainers valued the PSs’ opinions, empathised with them and were interested in them as individuals. The PSs described the trainers as ‘friends’ and felt that the trainers understood them:
They [the trainers] related well to the girls and their delivery style supported SDT. Connections between the girls and with trainers [are] clear.
Observation notes
They were trusting. If you said something to them, you really felt you could trust them. They were just very friendly and stuff.
Post-training focus group 2
I could see they’re still not there [engaged], and when they sat down is when I suggested different ideas as a group, because I know when I was that age I was a really, really shy girl so I wouldn’t want to say anything.
Trainer 2
Experience of being a peer supporter
What girls did to peer support
The PSs reported engaging in little peer-supporting activity. Efforts to peer support included suggesting active travel and leading by example:
We went to the gym last year just before the end of term, and, we kind of spoke to everyone about it, like a few of our friends. And then they invited a few of their friends to go.
During-intervention focus group 1
One of my friends, we were, coming back from town or something. She was like, ‘Oh, no, I’ll get my mum to pick us up.’ I was like, ‘Why can’t we walk, to get some exercise?’
During-intervention focus group 2
PSs felt that they encouraged their peers to walk more or go to the gym:
And [girl name] and [girl name] house are, like, an hour away from each other, and we walked, like, all the way.
During-intervention focus group 2
There were a number of instances of PSs talking to family or non-female Year 8 peers:
I had a conversation with this year seven, who was in my tutor [group].
During-intervention focus group 1
Challenges of being a peer supporter
The main challenges and reasons many girls did little peer supporting was that they lacked confidence in approaching peers and encouraging them to be active, particularly peers whom they did not know:
A bit awkward if I just went up to someone and told their friends. It would be a bit weird to just come up to her in person.
During-intervention focus group 1
Despite the PS training dedicating sessions to the when, where and how of starting conversations and overcoming challenges, a barrier to PS activity was knowing how and when to start a conversation. Participants suggested including more activities in the training to support this:
You might have told us, like, how to start the conversation or something. Because, in a conversation, we don’t really – it doesn’t really bring it up that much.
During-intervention focus group 2
Participants also reported that many of their friends are already active:
Most of the girls in our class are already really active, so it’s kind of not really.

Perceived impact of the Peer-Led physical Activity iNtervention for Adolescent girls
The main impact that PSs perceived their role to have was improving their confidence and increasing their PA:
But it’s got me a lot more active, and it’s boosted my confidence a lot.
During-intervention focus group 1
The NPS Year 8 girls appeared to be aware of PLAN-A and were interested in it; however, PSs felt that it would be beneficial to have posters or to do a presentation to the rest of the year to raise awareness and help make their role easier:
I think more like getting all the girls together and talking about it, so, like, having like a presentation about what we’ve done because then all the girls will be in the room and nothing to be ashamed of.

Ancillary accelerometer study
In addition to testing the intervention design, data collection methods were also tested with the pilot school. Year 8 girls from the pilot school were asked to wear either waist or wrist accelerometers, or both, for a short period; their thoughts about these different methods were qualitatively assessed to inform data collection for the feasibility trial (see Appendix 6).
Implications of phase 1 findings on the Peer-Led physical Activity iNtervention for Adolescent girls
The formative research carried out in phase 1 facilitated a user-centred refinement of the ASSIST intervention to form PLAN-A. The pilot study allowed the school, student and PS recruitment methods to be tested and refined. In addition, the peer nomination activity, train the trainers and PS training were delivered, rehearsed and critiqued. The key implications of the formative work and pilot study for the design of these intervention components are presented in Appendix 1.
Description of final intervention elements
Figure 8 depicts the PLAN-A project logic model, including the process evaluation approaches taken to assess outputs and outcomes in addition to school context. The resources and elements of the intervention that were tested in phase 2 are presented in Table 5.
Self determination theory was used to inform the delivery and content of the PS training (Table 6). In terms of delivery, trainers were trained to facilitate the PS training in ways that support autonomy (e.g. empowerment to support peers and provide choice), competence (e.g. confidence in how to be an effective PS and support one’s peers’ competence to be active) and belonging (e.g. supportive network of PSs and being a trusted friend to one’s peers). The PS training was designed to encourage PSs to recognise and promote autonomous rather than controlled motivation for PA (focusing on health, challenge-seeking and social affiliation reasons rather than appearance and peer pressure), to support their peers’ needs for autonomy, competence and belonging and use autonomy-supportive language when diffusing PA messages (e.g. ‘I’m going to walk to school, will you come with me?’ versus ‘you need to do more activity so you do not get fat’).
Summary of phase 1
Phase 1 of PLAN-A was designed to test all intervention elements, from recruitment through to intervention delivery. As a result, a number of intervention elements were changed or adapted to take into consideration the views of the Year 8 girls, PSs and trainers. The PS recruitment process was refined to focus on how PSs should take pride in being nominated and the benefits they would gain from being a PS. Training content and expectations were also made clear to the PSs on recruitment. Trainers were recruited based on characteristics described by Year 8 girls and the train the trainers activity was adapted so that there was enough time to practically run through all activities and for trainers to familiarise themselves with the content, based on trainer suggestions. It was ensured that the PS training content was active and practical, rather than involving too much writing and listening, as well as concentrating on boosting PSs’ confidence to talk to others by practising peer support and covering what to do if they come across any difficulties or issues when peer supporting. These changes led to the creation of the final intervention that was implemented in phase 2: the feasibility trial.
