Happiness and Physical Activity in Special Populations: Evidence From Korean Survey Data

This article contributes to the literature on happiness by focusing on the effects of physical activity or sport participation on happiness or life satisfaction in a special population. Using survey data collected by the Korean Sports Association for the Disabled, all respondents were legally disabled. This study presents empirical evidence of positive "nonhealth effects" of physical activity on life satisfaction. Approximately a one-level jump in physical activity in the six-level score provided the same improvement in life satisfaction as one-quarter of the effect of the employment status change from unemployed to employed. Additionally, the empirical finding that the level of disability was insignificant in determining subjective well-being is consistent with a threshold argument. The authors' empirical results also support there being no adaptation to disability, in contrast to findings in the psychology literature.
