Background: Several theories have been established to explain physical activity (PA) participation. However, many of these theories might not be applicable to adolescent PA behavior as they require a high level of cognitive reflection. Weiss suggests a model for youth which is based on the theoretical concept of Harter, focusing on self-esteem within social, emotional, and developmental aspects to explain behavior. The aim of this study was to test the original and a social support focused alternative version of the Weiss-Harter-model, and to cross-validate the findings in two separate studies.
Methods: Data from two cross-sectional studies was retrieved and the models tested using structural equation modeling. Participants aged 11–17 years were recruited from a school (Study 1: N = 182) and from the German MoMo study (Study 2: N = 2,274). They filled in questionnaires about perceived competence, social support, self-esteem, PA enjoyment, and minutes of moderate-vigorous PA (MVPA).
Results: None of the studies showed a good model fit for the original model [Study 1: CFI = 0.870, RMSEA 0.118 (90% CI 0.081–0.158), χ$^{2}$ = 38.7, p < 0.01; Study 2: CFI = 0.871, RMSEA 0.148 (90% CI 0.140–0.155), χ$^{2}$ = 1112.6, p < 0.01], explaining only 12% and 17% of MVPA variance, respectively. ... mehr
