Broad strokes or fine points: Are dialectical behavior therapy modules associated with general or domain-specific changes?

Dialectical behavior therapy (DBT) has demonstrated effectiveness for a range of emotional difficulties, and DBT skills training groups may be necessary to produce symptom change. However, it is unclear how skills training groups influence outcomes. Specifically, is participation in DBT skills modules associated with general effects (i.e., changes in multiple domains) or domain-specific effects (i.e., changes in the conceptually relevant domain)? Participants recruited from a university training clinic (n = 87; 75.9% diagnosed with borderline personality disorder) participated in standard DBT for 6 months. We conducted hierarchical linear mixed models to test whether self-reported changes in emotion regulation, interpersonal problems, and distress tolerance were associated with the specific DBT module intended to target that outcome. In 3 models, we regressed end-of-module ratings of each of our measures of interest on (a) premodule ratings of each measure of interest, (b) time, and (c) dummy-coded module completed. Although all modules were associated with similar reductions in emotion dysregulation, the Emotion Regulation module was associated with the greatest improvements in both interpersonal problems and distress tolerance. In contrast, the first skills module completed was unrelated to changes in any of these domains. These results suggest that Emotion Regulation skills are associated with improvements in patient symptoms across relevant domains and offer potential directions for optimizing the delivery of DBT.

Validation predicting premature drop-out from treatment provided in training clinics.

BACKGROUND: Therapist validation in treatment is theorized to be related to positive outcomes (Linehan, 1993), including keeping patients in therapy longer. AIMS: We sought to evaluate the role of therapist validation from both therapists' and clients' perspectives as a predictor of drop-out from psychotherapy in three cognitive behavioural training clinics. METHOD: Clients in psychotherapy (n = 50; 80% female; 82% Caucasian) and their trainee therapists (n = 22; 68% female; 86% Caucasian) rated validation by the therapist at each of four early sessions of therapy. RESULTS: After accounting for symptom severity, clients who reported greater therapist validation were less likely to drop out of treatment. Therapist ratings of their own validating behaviours were unrelated to client drop-out. Therapist experience moderated the relation between client-rated validation and drop-out, such that validation was unrelated to drop-out for more experienced therapists. CONCLUSIONS: Assessing and attending to client perceptions of validation by the therapist early in treatment, with brief self-report inventories, can alert therapists to clients at greater risk of drop-out.

The within-person effects of validation and invalidation on in-session changes in affect.

In the article, some values in Table 1 were incorrectly marked with asterisks as significant. The corrected table appears in the erratum.] Validation is the accurate reflection of someone's internal experiences. Validation has been theorized to enhance the process of therapy and facilitate effective outcomes (Lynch, Chapman, Rosenthal, Kuo, & Linehan, 2006). Additionally, validation may play an integral role in reducing emotional arousal specifically for individuals with borderline personality disorder (BPD). There is little research on the relation between validation and therapy outcomes such as affect change. In the current study, we tested the relations among self-reported validation and invalidation and in-session changes in positive and negative affect with a sample of 52 clients in treatment. Further, we examined BPD features as a moderator of the relations between self-reported validation and invalidation and in-session changes in affect. We disaggregated within-person from between-person effects using client reports of validation and invalidation during Sessions 3 to 7. Greater within-person validation was associated with decreased postsession negative affect, whereas greater within-person invalidation was associated with increased postsession NA. Neither validation nor invalidation was related to changes in positive affect. Further, at elevated levels of BPD features, validation, but not invalidation, was associated with decreases in negative affect. BPD features did not moderate the relation between validation or invalidation and postsession positive affect. These results provide empirical evidence that patient-reported validation and invalidation predict changes in negative affect during sessions. Additionally, these results suggest that patients with elevated BPD features are particularly responsive to validation during therapy sessions, and as such, provide an avenue for navigating the in-session negative emotional arousal that these patients often experience.

Flexible, yet firm: A model of healthy emotion regulation.

We propose a model of healthy intentional emotion regulation that includes (1) a large repertoire of (2) adaptive strategies that (3) one persists with despite initial negative feedback. One hundred forty-four undergraduates (average age = 19.20 years; 68% female, 79% Caucasian) completed a novel performance task indicating what they would think or do to feel better in response to eleven stressful vignettes. After their initial response, participants indicated four more times how they would respond if their previous strategy was not working. Raters categorized each response as an emotion regulation strategy and coded the adaptiveness of each strategy. Participants self-reported Neuroticism, Extraversion, Conscientiousness, Borderline Personality Disorder (BPD) symptoms, and depressive symptoms. We regressed each personality dimension and psychopathology symptom on our model of healthy emotion regulation. Neuroticism was negatively associated with adaptiveness and persistence. Extraversion was positively associated with adaptiveness. Conscientiousness was positively associated with repertoire, adaptiveness, and persistence, while BPD symptoms were negatively associated with all three variables. Depressive symptoms were negatively associated with persistence. These preliminary findings suggest that people with larger repertoires of more adaptive emotion regulation strategies who persist with these strategies despite initial negative feedback report less personality pathology and psychological distress.

Trichotillomania and personality traits from the five-factor model

Objective: To examine whether personality traits have predictive validity for trichotillomania (TTM) diagnosis, pulling severity and control, and hair pulling style. Methods: In study 1, logistic regression was used with TTM cases (n=54) and controls (n=25) to determine if NEO Five-Factor Inventory (NEO-FFI) personality domains predicted TTM case vs. control classification. In study 2, hierarchical multiple regression was used with TTM cases (n=164) to determine whether NEO-FFI personality domains predicted hair pulling severity and control as well as focused and automatic pulling styles. Results: TTM case vs. control status was predicted by NEO-FFI neuroticism. Every 1-point increase in neuroticism scores resulted in a 10% greater chance of TTM diagnosis. Higher neuroticism, higher openness, and lower agreeableness were associated with greater pulling severity. Higher neuroticism was also associated with less control over hair pulling. Higher neuroticism and lower openness were associated with greater focused pulling. None of the personality domains predicted automatic hair pulling. Conclusions: Personality traits, especially neuroticism, can predict TTM diagnosis, hair pulling severity and control, and the focused style of pulling. None of the personality traits predicted automatic pulling. Longitudinal studies are needed to determine whether personality variables predispose to TTM onset, impact disorder course, and/or result from hair pulling behavior.

Replication study of the milwaukee inventory for subtypes of trichotillomania-adult version in a clinically characterized sample.

In the present study, we evaluated the Milwaukee Inventory for Subtypes of Trichotillomania-Adult Version (MIST-A) in a replication sample of clinically characterized hair pullers using exploratory factor analysis (EFA; N = 193). EFA eigenvalues and visual inspection of our scree plot revealed a two-factor solution. Factor structure coefficients and internal consistencies suggested a 13-item scale with an 8-item "Intention" scale and a 5-item "Emotion" scale. Both scales displayed good construct and discriminant validity. These findings indicate the need for a revised scale that provides a more refined assessment of pulling phenomenology that can facilitate future treatment advances.

Body esteem in adolescent hair pullers.

BACKGROUND AND AIMS: Trichotillomania (TTM) often first presents in adolescence, a developmental period marked by vulnerability in body image. To date, no one has studied the relationship between this disorder and body esteem. METHODS: 49 adolescents with DSM-IV TTM or chronic hair pulling (HP) and 23 control adolescents were administered diagnostic assessments and self-report measures of hair pulling and body esteem. RESULTS: HP youth vs. controls reported lower levels of body esteem on all Body-Esteem Scale for Adolescents and Adults (BESAA) subscales (appearance, attribution and weight satisfaction). HP contributed to lowered body esteem, independent of comorbid anxiety or depression. As expected, HP youth with vs. without comorbid anxiety or depression reported lowered levels of body esteem. Further, greater HP severity and distress were significantly associated with lower levels of body esteem. HP severity alone but not distress/impairment predicted lower levels of body esteem, independent of comorbid anxiety and depression. CONCLUSIONS: Both hair pulling and comorbid anxiety and depression can independently impact body esteem in adolescent hair pullers.

The relationship between hair pulling style and quality of life.

BACKGROUND: Past research has found different associations between hair pulling (HP) variables and quality of life (QOL), especially after controlling for depression. This study examined HP styles (automatic vs focused) for their associations with QOL and whether depression accounted for these relationships. METHODS: Our sample consisted of 187 adults who met DSM-IV diagnostic criteria for trichotillomania (TTM) or chronic HP (TTM criteria except B and/or C). Clinician-administered interviews were used to diagnose TTM/HP. Participants completed self-report scales for HP style and severity, QOL, and severity of depression. RESULTS: Significant correlations were reported between QOL and the focused style of HP, as well as with interference and distress from HP. Exploratory analyses also revealed a correlation between number of HP sites and QOL. None of the correlations remained significant after controlling for severity of depression. CONCLUSIONS: These results indicate that future research on HP style also should consider the impact of co-occurring depressive symptoms. Interventions addressing both depression and HP should be considered in treatment planning to optimize outcomes.

A family study of trichotillomania and chronic hair pulling.

Little is known about the etiology of hair pulling (HP) and its relationship to other obsessive compulsive (OC) spectrum disorders. In a large-sample family study, we examined the familial aggregation of HP and co-transmission of obsessive compulsive disorder (OCD) and skin picking (SP). Our sample consisted of 110 proband cases with HP and 48 controls without HP, plus 128 first-degree case relatives and 50 first-degree control relatives. Case versus control relatives had higher recurrence risk estimates for both HP and OCD but not SP. The finding that HP is familial is consistent with the only existing twin study. Additional analyses suggest that there may be a familial subtype of HP with comorbid OCD. Those adult proband cases with HP + OCD had more anxiety and depression than cases without OCD. Probands with HP + OCD also had earlier onset of OCD. Identification of an HP subtype with comorbid OCD may have significant theoretical and treatment implications. The data did not provide evidence for an etiologic relationship between HP and SP. Replication of these findings in future studies with larger cohorts of case and control relatives is warranted.

DBT-enhanced cognitive-behavioral treatment for trichotillomania: A randomized controlled trial.

Background and aims Limited treatment options are available for trichotillomania (TTM) and most have modest outcomes. Suboptimal treatment results may be due to the failure of existing approaches to address all TTM styles. Methods Thirty-eight DSM-IV TTM participants were randomly assigned across two study sites to Dialectical Behavior Therapy (DBT) -enhanced cognitive-behavioral treatment (consisting of an 11-week acute treatment and 3-month maintenance treatment) or a minimal attention control (MAC) condition. MAC participants had active treatment after the 11-week control condition. Follow-up study assessments were conducted three and six months after the maintenance period. Results Open trial treatment resulted in significant improvement in TTM severity, emotion regulation (ER) capacity, experiential avoidance, anxiety and depression with changes generally maintained over time. In the randomized controlled trial, those with active treatment had greater improvement than those in the MAC condition for both TTM severity and ER capacity. Correlations between changes in TTM severity and ER capacity were not reported at post-treatment but did occur in maintenance and follow-up indicating reduced TTM severity with improved ER capacity. Conclusions DBT-enhanced cognitive-behavioral treatment is a promising treatment for TTM. Future studies should compare this approach to other credible treatment interventions and investigate the efficacy of this approach in more naturalistic samples with greater comorbidity.
