研究概览

简要总结

Research has shown that people with depressive symptoms maintain negative expectations even if they have positive experiences that contradict their expectations. Healthy people, however, change their expectations after unexpected positive experiences. In this experimental study, it will now be examined whether there are also differences between healthy people and people with depressive symptoms in dealing with unexpected negative experiences.

详细描述

Research has already shown that people with depressive symptoms continue to hold on to negative expectations even if they have positive experiences that contradict their expectations. By contrast, healthy people change their expectations after unexpectedly positive experiences. In this experimental study, the authors will now examine whether there are also differences between healthy people and people with depressive symptoms in processing unexpectedly negative experiences. It is hypothesized that people with depressive symptoms change their expectations in a negative direction after unexpectedly negative experiences, while healthy people continue to hold on to an optimistic view.

研究组 & 干预措施

Expectation confirmation

Experimental

The participants in this group receive manipulated feedback indicating that their performance was very good in the test they had previously worked on. This feedback is intended to confirm the previously induced positive expectations of their own performance.

干预措施: Expectation confirmation (Behavioral)

Expectation disconfirmation

Experimental

The participants in this group receive manipulated feedback indicating that their performance was below average in the test they had previously worked on. This feedback is intended to negatively disconfirm the previously induced positive expectations of their own performance.

干预措施: Expectation disconfirmation (Behavioral)

结局指标

主要结局

2-Item Performance Expectations Scale - generalized

时间窗: Immediately before the performance test and immediately after completion of the performance test

Changes from baseline to postassessment in generalized performance expectations. Each item is scored from 1 to 7 (1 = very negative expectations, 7 = very positive expectations), yielding a total score between 2 and 14. Higher total scores reflect more positive expectations.

次要结局

  • 2-Item Performance Expectations Scale - task-specific(Immediately before the performance test and immediately after completion of the performance test)
