The present study investigated test-retest variation in Body Image Questionnaire scores among a sample of British school children. 112 participants from three different school years (aged 12 to 14 years) completed the Body Image Questionnaire on two occasions separated by a 6-wk. period. No intervention designed to change perceptions of body shape took place, hence, tesr-retest scores should be stable. Analysis indicated a significantly greater variation among 12- and 13-yr-olds upon retest, but not for 14-yr.-olds. Research is needed investigating factorial and test-retest stability of the measure for use with children aged 12 or under.
