Causal uncertainty and psychological well-being: the moderating role of accommodation (secondary control).

Causal uncertainty about one's own outcomes (CU-Own) is associated with negative affect, depression, and a lack of perceived primary control. We predicted that accommodation, or secondary control, would act as a psychological buffer for high-CU-Own individuals, reducing negative affect and depression.We tested this hypothesis in two studies: one cross-sectional (Study 1) and one longitudinal (Study 2). Participants completed measures of CU-Own, harmony control, and depression in Study 1 and measures of CU-Own, harmony control, flexible goal adjustment, and negative affect in Study 2. Analyses reveal that the CU-Own-depression and CU-Own-negative affect associations were weaker when harmony control or flexible goal adjustment was high. Additional analyses in Studies 1 and 2 examined the roles played by primary control, locus of control, optimism, pessimism, and causal importance. Implications for the CU and accommodation literatures are discussed.
