Discontented people: reactivity and locus of control as determinants of subjective well‐being

This study examines the effects of reactivity temperament and locus of control variables on subjective well‐being (SWB). SWB is operationalized as positive affect, the absence of somatic concerns, and heightened life satisfaction. The study hypotheses were that (1) reactivity and locus of control influenced SWB and that (2) affect either mediated or moderated the influence of these traits on SWB. As expected, high reactivity and external locus of control were associated with lower SWB, whereas low reactivity and internal locus of control were associated with higher SWB. However, the data indicate that reactivity and locus of control influenced different components of SWB and that locus of control predicted SWB more consistently than reactivity. Somatic health is influenced by reactivity, locus of control and negative affect, but not positive affect. Current life satisfaction is influenced by locus of control—but not reactivity—and by both positive and negative affect. Hope is related to reactivity but not to either locus of control or affect. The data corroborate the expectation that affect serves as a mediator in the trait—SWB relations, whereas the view that affect moderates the effect of stable dispositions on SWB finds scant support.
