Correlations between depressive symptom severity, perceived stress and cognitive bias composites.

Note1. ap<.10 bp<.05 cp<.01 dp<.001 Note2. BDI-II = Beck Depression Inventory—II; PSS = Perceived Stress Scale (measured at time 2). Note3. Weak to moderate correlations were observed between individual cognitive biases at Time 1. Sustained attention correlated with selective orienting, r = .54, p<.001, and memory, r = .39, p<.01, but not with interpretation, r = .18, p = .20. Selective orienting correlated with interpretation, r = .34, p<.05, but not with memory bias, r = .21, p = .13. Interpretation correlated with memory bias, r = .52, p<.001. None of the four cognitive biases were redundant and the strength of the observed correlations is similar to correlations reported between cognitive content variables [17].
