Dispositional Optimism and Judgments of Future Life Events: Affective States as Moderators

This research examined the relation between dispositional optimism and judgments of future life events and whether this relation is moderated by affective states. In this study the moderating role of experimentally induced affective states, using film clips (N = 259), was investigated. After filling in the questionnaire for dispositional optimism, the participants were randomly assigned in the experimental conditions in order to induce positive versus negative affective states. Finally, the participants filled in the affective states and judgments of future life events scales. The results indicated that the participants with a higher level of optimism had the tendency to judge positive events as more likely and negative events as less likely to happen in the future. We found evidence for affective states as moderators; the association between dispositional optimism and judgments of future positive events depended on experimentally induced affective states. Specifically, in positive affective state condition, the association between dispositional optimism and judgments of future positive events was weaker than in both negative affective state and control conditions. The implications of these findings for understanding the role of optimism and affective states, in determining the judgments about the likelihood of future events are discussed.
