This study investigated the effectiveness of a Team Building Through Physical Challenges (TBPC; Glover and Midura, 1992) program on the self-conceptions of physical education students in Grades 6 and 7. The treatment group was exposed to one TBPC activity every second week for 8 months, while the second group completed the regular physical education curriculum without any TBPC activities. Data were analyzed using 2 (treatment/control) x 2 (preintervention/postintervention) x 2 (male/female) repeated measures analysis. Results at postintervention revealed that both male and female students in the treatment group were significantly higher on perceptions of global self-worth, athletic competence, physical appearance, and social acceptance than the control group. Female students in the treatment group were also significantly higher on perceptions of scholastic competence and behavioral conduct than female students in the control group. Effect sizes indicated that meaningful as well as significant differences in self-conceptions were created by the TBPC program.
