Beliefs about the automaticity of positive mood regulation: examination of the BAMR-Positive Emotion Downregulation Scale in relation to emotion regulation strategies and mood symptoms

Dampening of positive affect and depression: A meta-analysis of cross-sectional and longitudinal relationships

Dampening responses to positive affect have been posited to confer vulnerability to depression, but longitudinal studies have not consistently shown dampening tendencies to predict follow-up depression. The cross-sectional, longitudinal, and cross-lagged relationships between dampening and depression were determined using meta-analytic methods. A systematic literature search of the PsycINFO and PubMed databases supplemented by Google Scholar yielded 60 samples suitable for inclusion in the cross-sectional analyses and 12 samples meeting criteria for the longitudinal analyses. In the first meta-analytic study to examine the relationship between dampening and depression, we found dampening to be associated with depression both cross-sectionally (r = .45) and prospectively (r = 0.34). Crucially, dampening at baseline remained a significant predictor of follow-up depression even after controlling for baseline levels of depression in cross-lagged analyses (β = .09). A bidirectional effect was also found, with baseline levels of depression predicting follow-up tendencies to engage in dampening (r = 0.36). This relationship was again diminished but remained significant after controlling for initial levels of dampening (β = .14). These results suggest that dampening responses to positive affect are a risk factor for the development of depression and highlight the importance of targeting dampening cognitions in treatment.

Difficulties in emotion regulation in bipolar disorder: A systematic review and meta-analysis

BACKGROUND

Bipolar disorder (BD) is a severe mental disorder characterized by mood swings and functional impairment. Although alterations in emotional regulation (ER) are a key feature, a comprehensive meta-analysis on abnormalities in emotion regulation in BD is still lacking.

METHODS

We performed a random-effects meta-analysis on studies comparing the ER measured with the Difficulties in Emotion Regulation Scale (DERS) in BD and healthy controls (HC) or borderline personality disorder (BPD) and calculated the standardized mean difference (SMD) of the total DERS score between those with BD and HC (primary outcome). Secondary outcomes were the SMD of the DERS subscales between BD and HC, as well as the SMD of the total score of DERS and the subscales between BD and BPD.

RESULTS

Twelve studies (858 BD, 540 BPD, 285 HC) were included. Compared to HC, BD showed significantly higher total DERS score (k=8, SMD 0.962, p<0.001) and subscale scores, including non-acceptance (k=6, SMD=0.85, p<0.001), goal-directed behavior (k=6, SMD=0.894, p<0.001), impulse control (k=6, SMD=1.08, p<0.001), strategies (k=6, SMD=1.25, p<0.001) and emotional clarity (k=6, SMD=0.694, p=0.001). Relative to BPD, BD presented significantly lower scores in all the DERS subscales. Sensitivity analyses confirmed the main analyses. The age of the participants and sample size moderated the primary outcome.

LIMITATIONS

The small number of studies and the cross-sectional design limit the generalizability of the results.

CONCLUSIONS

Our findings suggest that alterations of specific ER abilities are present in BD and their magnitude is smaller relative to BPD. Future therapeutic interventions should target ER strategies.
