The predictive validity of the DSM-5 alternative model for borderline personality disorder: Associations with coping strategies, general distress, rumination, and suicidal ideation across one year

Compatibility of Linehan's biosocial theory and the DSM-5 Alternative Model of Personality Disorders for borderline personality disorder

Borderline personality disorder (BPD) is characterized by affective, interpersonal, and identity instability, as well as marked impulsivity. There is evidence that BPD may be best operationalized dimensionally using models such as the Alternative Model for Personality Disorders (AMPD) described in Section III of the Diagnostic and Statistical Manual for Mental Disorders (DSM). Moreover, biosocial theory is a well-known etiological theory of BPD emphasizing emotion dysregulation, inherited impulsivity, and development within invalidating contexts as key etiological mechanisms. Given that current research and clinical efforts for BPD are informed by both nosology and etiology, this narrative review examined how well biosocial theory (a) aligns with AMPD conceptualizations, (b) accounts for psychiatric comorbidity, and (c) accounts for heterogeneity in BPD presentation. Findings suggested that tenets of biosocial theory align well with Criteria A and B of the AMPD; however, biosocial theory focuses narrowly on roles of emotion dysregulation, impulsivity, and invalidating contexts, and empirical support is lacking in some ways for several etiological explanations proposed by biosocial theory. Additionally, although biosocial theory captures empirically supported features of BPD and emphasizes high-risk subgroups, the theory may not account for lower-risk subgroups. Finally, the theory accounts for diagnostic co-occurrence via the central role of emotion dysregulation, but biosocial theory may not be specific to BPD and may broadly apply to a range of psychopathology. Based on the literature reviewed, implications for future research and clinical efforts are highlighted.

Evaluating distress as a moderator of the relationship between drinking identity and hazardous drinking during the post-college transition

Drinking identity (the extent to which one associates the self with drinking alcohol) is a robust predictor of young adult hazardous drinking (HD; heavy drinking and alcohol-related problems), and decreases in drinking identity have been linked to the decline in HD that often occurs following college graduation. Identifying moderators is key to recognizing who is most at risk for continued HD given a drinking identity vulnerability. Using data from a longitudinal study of graduating college students from the U.S., we evaluated distress (depression, anxiety, stress symptoms) as a potential moderator. Between- and within-person components of drinking identity and distress were evaluated to consider both individual differences and variations within a person across time and changing contexts. Study hypotheses and data analysis plan were preregistered. Graduating college students who met HD criteria (N = 422) completed implicit and explicit drinking identity measures (assessed using reaction time and self-report measures, respectively), distress symptom questionnaires, and self-reported alcohol consumption and problems at four-month intervals for 2.5 years. Results supported moderation at the between-person level for alcohol consumption, with higher levels of implicit drinking identity and distress linked to greater subsequent alcohol consumption. Only between-person main effects for (explicit) identity and distress were linked to more subsequent alcohol-related problems. Though moderation findings were mixed, having a stronger drinking identity and/or greater distress was linked to continued HD risk in this sample. Individuals with these risk factors may benefit from enhanced prevention efforts to help graduates transition out of HD post-college.
