title: Veridicality of self-concept of strength in male adolescents.
abstract: Changes in physical self-concept and veridicality (i.e., the appropriateness of one's self-perceptions to reality) during childhood and adolescence are related to performance in physical fitness, exercise, and global self-esteem, particularly in male adolescents. This cross-sectional study examined the relation between the self-concept of strength and actual strength in groups of male adolescents ages 12 to 15 years. For this purpose, 889 male adolescents (M age = 13.2 yr., SD = 1.0) were questioned about their self-concept of strength, after which a test of strength was carried out. The results showed that the correlation between self-concept of strength and actual strength was higher in older (14- and 15-year-old) than younger (12- and 13-year-old) adolescents. There was a statistically significant association between age group and veridicality, indicating that realistic self-concept is underrepresented among younger, but overrepresented among older adolescents. No association was found between the adolescents' physical activity and veridicality. The consequences for further research on the development of veridicality in the physical domain are discussed.
