Purpose: Adopting a socio-ecological perspective, this study assessed the influence of social status and social economic status on adolescent intrinsic motivation for physical activity. A social network measure of social status was employed which permits analysis of both popularity and relatedness. It was predicted that higher social status would predict higher levels of self-determined motivation (intrinsic) for physical activity, that increasing age and social status would moderate this relationship and that boys with higher social status would show higher levels of intrinsic motivation for physical activity.

Methods: One hundred and nine (59 males and 50 females) participants aged 11 years 1 month to 16 years 9 months (M=13 years 5 months) were recruited from schools across the South East of the UK. They completed measures of social economic status, self-determined motivation (BREQ-2) towards physical activity participation and ratings of school peer’s social status (generating popularity and relatedness scores).

Results: Hierarchical multiple regression showed that males displayed higher self-determined motivation towards physical activity participation than females; social status was not a significant predictor. Age, gender and social economic status did not predict motivation for physical activity. Social status, specifically popularity, did however correlate with participation for the older participants aged 15 years 2 months to 16 years 9 months. Qualitative, visual interpretation of the social networks of popularity and relatedness showed a mixed influence on motivation across individuals. For example, females with higher and lower popularity and relatedness had higher and lower self-determined motivation respectively to participate in physical activity.

Conclusions: In partial support of a socio-ecological framework, age related to increased participation in physical activity. The mixed individual findings regarding the influence of popularity and relatedness in relation to age and social economic status on self-determined motivation to participate in physical activity suggest the importance of assessing the interplay of multiple socio-ecological factors using inclusive social network analysis on an individual basis in relation to understanding and promoting intrinsic rather than regulated motivation towards physical activity.
