Description:
Test-retest and construct validity of Contour Drawing Rating Scale (CDRS) scores were examined in 1056 Grades 7 and 8 girls. Questionnaires were completed four times, including retests at 2, 6 and 14 weeks. Test-retest reliability for current size, ideal size and current-ideal discrepancy mostly exceeded 0.70 (0.65-0.87, for the full sample, with higher rs for shorter retest periods). Ideal and current size ratings increased slightly over time. High correlations between perceived current figure and measured body mass index; moderate rs between current-ideal discrepancy and body dissatisfaction and restrained eating; and very low or no significant correlations with social desirability supported construct validity in this group. The study supported the use of the CDRS in early adolescent girls.
