This work examined the effect of sex on factor structure of a Chinese version of the 1989 COPE questionnaire with a sample of 617 Hong Kong adolescents (Mdn age = 14 yr.). Some scales had low internal consistency reliability for both sexes. Not all 15 scales could be identified as unique factors through exploratory factor analysis separately for both sexes (275 boys, 338 girls, 4 unknown). In a second-order factor analysis, both sexes' data had factors related to problem-focused coping and avoidance/escaping coping, and these two factors were only weakly correlated. An emotion-focused factor was observed in girls' data, but not boys' data.
