Cognitive content-specificity in future expectancies: role of hopelessness and intolerance of uncertainty in depression and GAD symptoms.
The present study examined cognitive content-specificity in future-event predictions associated with symptoms of depression and generalized anxiety disorder (GAD). College undergraduates (N=284) completed measures of depression, GAD, and rated their certainty that a given set of positive and negative outcomes were or were not likely to happen in their future. Participants also completed measures of hopelessness and intolerance of uncertainty (IU). Individuals (N=263) completed the same measures again 6 weeks later. Certainty in an absence of positive future outcomes was associated with symptoms of depression but not GAD, and hopelessness mediated this relationship - concurrently and when examining change scores over 6 weeks. Certainty in negative outcomes was concurrently associated with both symptoms of depression and GAD, and hopelessness partially mediated these relationships. IU predicted concurrent increases in depression and GAD symptoms, and negative-outcome certainty partially mediated the IU-depression but not the IU-GAD symptom relationship. Change in certainty did not mediate the relationship between changes in IU and GAD symptoms but partially mediated the relationship between change in IU and depression symptoms over time. Hopelessness appears to play a unique role in the relationship between reduced anticipation of positive future outcomes and depression. Although less clearly suggested by the data, IU may contribute to both depression and GAD symptoms but may do so through different pathways.
