Examining the relationship between subtypes of rumination and non-suicidal self-injury: A meta-analytic review

INTRODUCTION

Non-suicidal self-injury (NSSI) is a highly prevalent maladaptive behavior, often used to cope with intense negative affect. Rumination is an emotion regulation strategy that leads to fixation on and exacerbation of (typically) negative affective states. However, studies examining the relationship between rumination and NSSI have yielded mixed results, showing high degrees of heterogeneity.

METHODS

The present study conducted meta-analyses (k = 50) of the association between overall rumination and NSSI, and independent meta-analyses for each of four subtypes of rumination (general, depressive, brooding, reflection rumination). Potential moderators that may influence the magnitude of these relationships were also examined.

RESULTS

A small-to-moderate positive association between rumination and NSSI was found independent of rumination subtype. Moderating effects included NSSI outcome measure and study design for overall rumination and general rumination, respectively. Race was found to moderate the relationships between both brooding and depressive rumination and NSSI, though in inverse directions. An analysis of effect heterogeneity across studies suggested that undetected moderators may be present.

CONCLUSION

Results of this study support the relationships between rumination subtypes and NSSI and identify factors that may impact these relationships. Continued research is needed to understand this association, particularly in more varied subtypes of rumination and cognitive-affective moderators.

A systematic review with meta-analysis of cognitive bias modification interventions for anger and aggression

Aggression and anger are associated with interpretation and attention biases. Such biases have become treatment targets for anger and aggressive behavior in cognitive bias modification (CBM) interventions. Several studies have evaluated the efficacy of CBM for the treatment of anger and aggressive behavior, with inconsistent results. The present study meta-analytically analyzed 29 randomized controlled trial studies (N = 2334) published in EBSCOhost and PubMed between March 2013 and March 2023 assessing the efficacy of CBM for anger and/or aggression. Included studies delivered CBMs that addressed either attention biases, interpretation biases, or both. Risk of publication bias and potential moderating effects of several participant-, treatment- and study-related factors were assessed. CBM significantly outperformed control conditions in the treatment of aggression (Hedge's G = -0.23, 95% CI [-0.35, -0.11], p < .001) and anger (Hedge's G = -0.18, 95% CI [-0.28, -0.07], p = .001) independent of treatment dose, participant demographic characteristics, and study quality, though overall effects were small. Follow-up analyses demonstrated that only CBMs targeting interpretation bias were efficacious for aggression outcomes, but not when baseline aggression was accounted for. Findings suggest that CBM demonstrates efficacy for the treatment aggressive behavior and to a lesser extent, anger.

Cognition and Non-Suicidal Self-Injury: Exploring Relationships with Psychological Functions

OBJECTIVE

Non-suicidal self-injury (NSSI) is strongly associated with difficulties in emotion regulation, but its relationships with maladaptive cognitive processes are less clear.

METHOD

The current study examined relationships between self-reported NSSI (presence, number of methods, frequency, recency, duration, functions) and negative cognitive processes (rumination, worry, self-criticism, perceived burdensomeness, thwarted belongingness) among 1,357 undergraduates. Cognition variables were submitted to exploratory factor analysis (EFA), and relationships were examined between the resulting factors and NSSI history (among the full sample) and NSSI severity and functions (among those with a history of NSSI).

RESULTS

The EFA derived two higher order cognitive factors: repetitive negative thinking (RNT) and negative self-perception (NSP). Both RNT and NSP were significantly higher among participants with than those without a history of NSSI. Among those with NSSI, NSP, but not RNT, was positively related to lifetime NSSI frequency and number of methods, as well as recency (presence in the past 12 months) and total duration (in years) of NSSI engagement. Moreover, RNT and NSP were positively associated with aggregate intrapersonal (but not interpersonal) functions of NSSI. The two cognitive factors demonstrated differential relationships with the individual intrapersonal NSSI functions.

CONCLUSIONS

Higher order categories of cognitive risk factors may have unique relationships with functions and severity of NSSI, with possible implications for more targeted approaches to risk assessment and intervention.HighlightsNegative thinking and self-perception were higher in people who engage in NSSI.Negative self-perception was associated with greater NSSI severity.Negative thinking and self-perception had different relations to NSSI functions.

Emotion regulation strategies among individuals with borderline personality disorder relative to other groups: A review

Borderline personality disorder (BPD) is associated with difficulties in emotion regulation (ER) abilities. Investigations of ER strategies in BPD have been less robust. This systematic review identified 55 studies comparing ER strategy use between individuals diagnosed with BPD versus psychiatric and non-psychiatric comparison groups. Individuals with BPD reported more frequent maladaptive and less frequent adaptive ER strategy use than non-psychiatric controls. Results were less consistent relative to psychiatric comparison groups, though individuals with BPD reported greater self-criticism and avoidance. Groups responded comparably to instructed use of adaptive (but not maladaptive) ER strategies. This body of research would benefit from further examination of the roles of psychiatric comorbidity and problematic behaviours in the relationship between BPD and ER strategies.
