The Association Between Physical Activity and General Life Satisfaction in Lower Secondary School Students: The Role of Individual and Family Factors

The objective of the paper was to investigate the association between PA and general life satisfaction in adolescents, taking into account family affluence and selected psychological, family and school factors. The survey (2015) involved 4085 Polish lower-secondary school students. Life satisfaction was measured with the abridged Students’ Life Satisfaction Scale (SLSS). Vigorous Physical Activity, self-esteem, family affluence, family relations and the perception of the school environment were considered as independent variables. Hierarchical and path models were applied. The mean SLSS score was M = 4.66 (SD = 2.23), and 36.9% of its variability was explained—mainly by self-esteem. The impact of PA on self-esteem became stronger when family affluence decreased, which led to the conclusion that material status may modify the impact of behavioural factors on the SLSS scores’ variability in adolescence.
