\fEXCERPT FROM THE RESEARCH ARTICLE? The present study was designed to test the hypothesis that a session of summer camp would increase the self-esteem of economically disadvantaged school-age children from New York's inner-city neighborhoods. The sample included 68 American children, ages 6-12 years. . . As a measure of self-esteem, the Piers-Harris Children's Self-concept Scale. . ., an 80-item self-report questionnaire, was administered as a pretest and posttest. Total scores for self-esteem range from 0 to 80, with higher scores reflecting more positive self-evaluations. . . The scale taps six dimensions of self-esteem. . .: popularity (12 items), physical appearance and attributes (13 items), intellectual and school status (17 items), happiness and satisfaction (10 items), behavior (admission of problem behaviors) (16 items), and anxiety (14 items). On behavior and anxiety scales, higher scores indicate perception of fewer problems or less anxiety. p. 144 144 Size of treatment effect was based on Cohen's d for the overall score (d = .15) and for the popularity cluster scale (d = 25 ) .
