Working in prisons is a demanding career. While a growing number of studies have explored the predictors of job stress, job involvement, and job satisfaction, very few studies have examined how job stress, job involvement, and job satisfaction effect prison staff life satisfaction. Moreover, past studies on prison staff life satisfaction have all been conducted among those working in the United States. The current study examined how job stress, job involvement and job satisfaction were associated with satisfaction with life among surveyed staff at two Chinese prisons. Job involvement and job satisfaction had positive effects on life satisfaction, while job stress had a negative effect.
