A brief measure of guilt and shame: validation of the Guilt and Shame Questionnaire (GSQ-8)

Background: Guilt and shame regulate basic human processes such as social cognition and relations. Both emotions are also involved in the aetiology and maintenance of trauma-related mental disorders such as posttraumatic stress disorder (PTSD). However, a concise scale that adequately captures these constructs is currently lacking, impeding research efforts to understand them more thoroughly. Objective: To this end, we developed the eight-item Guilt and Shame Questionnaire (GSQ-8) in English, German, and Dutch. Method: We examined the reliability and validity of the GSQ-8 in a clinical sample of adults seeking treatment for childhood-trauma-related posttraumatic stress disorder (n = 209), a sample of adults who had suffered at least one traumatic life event reporting different levels of PTSD symptoms (n = 556), and a non-clinical sample of adults (n = 156). Results: Theory-driven confirmatory factor analyses confirmed two correlated latent factors guilt and shame with four items for each factor. Across all samples, two-factor models yielded better model fit than one-factor solutions. Measurement invariance across the three samples, gender, and Dutch and German language was mostly established. Guilt and shame composite scores were associated with PTSD symptoms, depressive symptoms, life satisfaction, mental health-related quality of life, and self-blame, thus supporting scale validity. Importantly, both subscales predicted PTSD symptoms, depression, life satisfaction, and mental health-related quality of life over and above cognitions of self-blame. Conclusions: The GSQ-8 is a parsimonious, reliable, and valid tool to assess guilt and shame in clinical, sub-clinical, and non-clinical populations, allowing applications across a broad range of research questions

EFFECTIVENESS OF PSYCHOLOGICAL TREATMENTS FOR BPD

This project contains the data that we used in our meta-analysis on the effectiveness of treatments for Borderline Personality Disorder (BPD). The attached excel file contains an overview of the included studies, outcomes, domains and effect sizes (and related statistics)

Effectiveness of Psychological Treatments for Borderline Personality Disorder and Predictors of Treatment Outcomes: A Multivariate Multilevel Meta-Analysis of Data from All Design Types

We examined the effectiveness of psychotherapies for adult Borderline Personality Disorder (BPD) in a multilevel meta-analysis, including all trial types (PROSPERO ID: CRD42020111351). We tested several predictors, including trial- and outcome type (continuous or dichotomous), setting, BPD symptom domain and mean age. We included 87 studies (N = 5881) from searches between 2013 and 2019 in four databases. We controlled for differing treatment lengths and a logarithmic relationship between treatment duration and effectiveness. Sensitivity analyses were conducted by excluding outliers and by prioritizing total scale scores when both subscale and total scores were reported. Schema Therapy, Mentalization-Based Treatment and reduced Dialectical Behavior Therapy were associated with higher effect sizes than average, and treatment-as-usual with lower effect sizes. General severity and affective instability showed the strongest improvement, dissociation, anger, impulsivity and suicidality/self-injury the least. Treatment effectiveness decreased as the age of participants increased. Dichotomous outcomes were associated to larger effects, and analyses based on last observation carried forward to smaller effects. Compared to the average, the highest reductions were found for certain specialized psychotherapies. All BPD domains improved, though not equally. These findings have a high generalizability. However, causal conclusions cannot be drawn, although the design type did not influence the results
