Cognitive bias modification for adult's depression: A systematic review and meta-analysis.

OBJECTS

This study aimed to elucidate the effect of cognitive bias modification on depression.

METHODS

This research included 10 randomized studies searching four major databases: PubMed, Embase, PsycINFO, and Cochrane Library, with a total sample size of 467. Moreover, they were examined for quality and possible publication bias.

RESULTS

Cognitive bias modification (CBM) had statistically significant results,  = -0.64, 95% CI = [-0.97-0.32]. The interpretation of cognitive bias modification shows the highest effect size,  = -1.45, 95% CI = [-2.05-0.88]. When the training place is located in the laboratory, the training effect is significant,  = -1.11, 95% CI = [-1.62-0.61]. The difference is statistically significant when the training environment was changed to home,  = -0.28, 95% CI = [-0.51-0.05]. CBM has a statistical effect on moderate-to-severe depression,  = -0.70, 95% CI = [-1.04-0.36].

CONCLUSION

We found that CBM had a moderate therapeutic effect on depression, whether the setting was at home or in the lab. Especially when the interpretation of cognitive bias modification (CBM-I) was used, we got the highest effect value. Furthermore, CBM has a statistical effect on moderate-to-severe depression.
