Cognitive Triad and Depression: A Meta‐Analysis of Cross‐Sectional and Longitudinal Studies

ABSTRACT A large body of research has examined the association between the cognitive triad (negative views of the self, the world and the future) and depression; however, findings regarding its strength and direction remain inconsistent. The present meta‐analysis systematically synthesized existing empirical evidence to evaluate both cross‐sectional and longitudinal associations between the cognitive triad and depression. A three‐level random‐effects model was used to pool correlation coefficients ( r ) for cross‐sectional associations, and cross‐lagged regression models were applied to test prospective relations. Fifty‐nine cross‐sectional studies (132 effect sizes) were included, demonstrating a strong overall association between the cognitive triad and depressive symptoms ( r = 0.596, 95% confidence interval, CI 0.546, 0.622). Depressive symptoms were most strongly associated with a negative view of the self ( r = 0.593), followed by a negative view of the world ( r = 0.558) and the future ( r = 0.538). Exploratory cross‐lagged analyses were conducted across eight longitudinal studies. Preliminary results suggested that depressive symptoms at Time 1 predicted more negative cognitive triad scores at Time 2 ( β = 0.160, 95% CI 0.100, 0.220). The prospective effect of the cognitive triad on later depressive symptoms appeared to be moderated by age group; this effect was significant among participants aged 15 years or older ( β = 0.187, 95% CI 0.112, 0.261) but not among those below 15 years ( β = −0.035, 95% CI −0.122, 0.051). The findings indicate a strong association between the cognitive triad and depressive symptoms. Furthermore, exploratory longitudinal analyses provide preliminary evidence for a prospective effect of depressive symptoms on subsequent negative cognitions and suggest a potential developmental shift in cognitive vulnerability to depression from late adolescence into adulthood.
