Comparisons of personality for selected groups of fifteen-year-old males.

Cattell's High School Personality Questionnaire and Gough's Adjective Checklist were administered to 73 15-yr.-old boys to compare personality for groups selected on the basis of extreme scores on maturation (skeletal development, age at achievement of peak height velocity), body type (body somatotype, body skinfolds), performance (body reaction time), strength, physical fitness and socioeconomic status. Multiple discriminant analyses indicated that the only significant difference in personality between groups was for early versus late maturers (skeletal development) on Cattell's scale. The personality scores for the remaining extreme groups did not differ on either of the scales, Cattell's or Gough's.
