Unified Protocol Versus Self‐Acceptance Group Therapy for Emotional Disorders in People With Severe Shame

Abstract

BackgroundSevere shame is a distressing negative emotion, accompanied by intense feelings of worthlessness that contributes to a broad panoply of psychological disorders. This study aimed to compare the effects on shame dysregulation of two transdiagnostic treatments, the Unified Protocol (UP) and Self‐Acceptance Group Therapy (SAGT). We additionally addressed the question of whether borderline personality disorder (BPD) can properly be regarded as an emotional disorder. The focus was on outcome measures, primarily shame that cut across individual diagnostic categories and capture emotional dysfunction broadly conceived.MethodsIndividuals suffering from a range of emotional disorders (including BPD) and high levels of shame were randomly allocated to treatment by either UP (N = 280) or SAGT (N = 282). Outcomes were measures of emotion dysfunction—shame, loneliness, neuroticism, emotional dysregulation, positive and negative affect—measured pre‐treatment, post‐treatment and at 3‐ and 6‐month follow‐ups.ResultsUP was superior to SAGT in showing better post‐treatment retention of therapeutic gains on all outcome measures over the 6‐month follow‐up period. Compared with those without a BPD diagnosis, those diagnosed with BPD showed significantly higher neuroticism and emotion dysregulation at baseline and a similar post‐treatment reduction in almost all outcomes.ConclusionsThe results support the use of both the UP and SAGT in the treatment of severe shame. The superiority of the UP over SAGT in reducing negative emotionality is interpreted in terms of the specific mechanisms targeted by the UP. The results provide support for the theoretical rationale for the UP as a treatment for dysregulated shame and for emotional dysfunction generally.
