in the context of this guideline, facilitated self-help (also known as guided self-help or bibliotherapy) is defined as a self-administered intervention, which makes use of a range of books or other self-help manuals, and electronic materials based on the principles of CBT and of an appropriate reading age. A trained practitioner typically facilitates the use of this material by introducing it, and reviewing progress and outcomes. The intervention consists of up to six to eight sessions (face-to-face and via telephone) normally taking place over 9 to 12 weeks, including follow-up.
