Cognitive models of depression posit that persistent negative self-referent thinking (PNSRT) is an important vulnerability factor for depressive symptoms. The mechanisms involved are still understudied, especially in adolescence. PNSRT has been assessed by a behavioural decision-making task, namely the emotional reversal learning task (ERLT). Within the ERLT, PNSRT is operationalised as the learning rate for negative self-reference. The first aim of the current study is to examine the association between PNSRT and depressive symptoms at baseline and follow-up. Second, the current (...) study investigated associations of PNSRT with temperamental and emotion regulation variables. We found no significant effect between PNSRT and baseline depressive symptoms, although the small effect size pointed in the expected direction. No significant prospective effect was found. Additionally, adolescents with greater capacity for response inhibition and better attentional control exhibited less PNSRT. No other significant associations were found with other temperamental dimensions or emotion regulation variables. In conclusion, while the small effect size of the cross-sectional association between PNSRT and depressive symptoms points in the expected direction, no significant evidence was found that PNSRT acts as either a concomitant or precursor to depressive symptomatology. However, the current study did find a relation between low effortful control and PNSRT. (shrink)

Emotion dysregulation (ED) is a vulnerability factor for affective disorders that may originate from deficits in cognitive control (CC). Although measures of ED are often designed to assess trait-like tendencies, the extent to which such measures capture a time-varying (TV) or state-like construct versus a time-invariant (TI) or trait-like personality characteristic is unclear. The link between the TV and TI components of ED and CC is also unclear. In a 6-wave, 5-month longitudinal study, community participants (n = 1281) completed the (...) Difficulties in Emotion Regulation Scale (DERS-16), a commonly used measure of ED and measures of CC. A latent variable (trait-state-occasion) model showed that the proportion of TI factor variance (.80) was greater than the TV factor variance (.19). Although TV factor stability was significant, the coefficients were small in magnitude. Furthermore, regression weights for the ED TI factor (average β = −.62) were significant and larger than those for the TV factor (average β = −.10) in predicting latent CC at each of the six-time points. These findings suggest that ED, as assessed by the DERS-16, is largely TI and this TI component is more strongly linked to CC than the TV component. (shrink)
