The importance of prototype similarity for physical activity: Cross-sectional and longitudinal associations in a large sample of young adolescents.

In the full model, there were no significant interactions between either sex or FSM and any of the predictor variables at the p < .005 level, although the interaction between sex and active prototype similarity approached significance (β = −0.11, 95% CI −0.19 to −0.03, p = .008): the positive relationship between change in prototype perception and change in physical activity was stronger for boys than girls.
