Cognitive bias modification of interpretation training for Chinese undergraduates with depressive symptoms

Abstract

Because depression is highly prevalent among Chinese undergraduates, it is crucial to develop an approach for early intervention and prevention. Cognitive bias modification of interpretation (CBM-I) has been shown to be an effective approach to alleviate anxiety. However, its utility in improving depression needs further verification. The current study sought to evaluate the efficacy of a four-session CBM-I program of depression prevention for Chinese undergraduates. Forty Chinese participants with depressive symptoms (Self-Rating Depression Scale, SDS ≥ 50) were randomly assigned to receive either a CBM-I training or a waitlist control condition. Test results of Ambiguous Scenarios Test for Depression-Related Bias and SDS indicate that the CBM-I training group have more positive interpretations and fewer symptoms of depression after the training compared to the control group. In addition, significant correlation was found between changes in depressive symptoms and changes in interpretation bias. The effect of the CBM-I on depressive symptoms was partially mediated by the change in interpretation bias. The study findings highlight the potential of CBM-I protocol as a brief, simple, and accessible approach for preventing depression.
