Changes in proposed mechanisms of action during an acceptance-based behavior therapy for generalized anxiety disorder

Emotion Regulation as a Mechanism of Change in an Acceptance-Based Emotion Regulation Group Therapy for Deliberate Self-Harm Among Women With Borderline Personality Pathology

Despite the clinical importance of deliberate self-harm (DSH) within borderline personality disorder (BPD), there are few empirically supported treatments for this behavior among individuals with BPD; and those that do exist are difficult to implement in many clinical settings. Thus, Gratz and colleagues developed an adjunctive emotion regulation group therapy (ERGT) for women with BPD that directly targets both DSH and its proposed underlying mechanism of emotion dysregulation. Although previous studies support the use of this ERGT in reducing DSH, no studies have examined emotion regulation as a mechanism of change in this treatment. Therefore, this study examined the mediating role of changes in emotion dysregulation in DSH improvement across two separate trials of this ERGT. As hypothesized, changes in emotion dysregulation mediated the observed reductions in DSH frequency. Results provide support for the theoretical model underlying this ERGT and highlight the importance of targeting emotion dysregulation in treatments for DSH.

Mediators of change in acceptance and commitment therapy for pediatric chronic pain

Even though psychological interventions are well established in the treatment of pediatric chronic pain, there is a clear need for further development, especially with severely disabled patients. However, optimizing effectiveness in psychological treatments for pain requires clarification of the mechanisms of action. Studies addressing change processes are scarce, however, particularly in relation to pediatric chronic pain. Acceptance and Commitment Therapy (ACT), as an extension of traditional cognitive behavior therapy, is essentially aimed at improving functioning by increasing the ability to act effectively in the presence of pain and distress, that is, psychological flexibility. ACT has shown promising results for both adult and pediatric chronic pain. In the present study, the mediators of change in an ACT-oriented treatment for pediatric chronic pain were examined using a bootstrapped cross product of coefficients approach. Pain interference and depression were used as outcome variables. Six different variables relevant to theories underlying ACT and cognitive behavior therapy were included in the analyses as possible mediators of change: pain impairment beliefs, pain reactivity, self-efficacy, kinesiophobia, catastrophizing, and pain intensity. Results illustrated that pain impairment beliefs and pain reactivity were the only variables that significantly mediated the differential effects of treatment on outcomes at follow-up. Also, these 2 mediators were shown to independently predict effects in outcome variables at follow-up while controlling for earlier effects in outcome, but only for the ACT condition. Although tentative, the pattern of results suggests that variables consistent with psychological flexibility mediate the effects of ACT-based interventions to improve functioning in patients with chronic debilitating pain.

Mindfulness- and acceptance-based interventions for anxiety disorders: a systematic review and meta-analysis

PURPOSE

Mindfulness- and acceptance-based interventions (MABIs) are receiving increasing attention in the treatment of mental disorders. These interventions might be beneficial for patients with anxiety disorders, but no prior reviews have comprehensively investigated the effects of this family of interventions on clinical samples. The aim of this study was to review and synthesize extant research on MABIs for patients with diagnoses of anxiety disorders.

METHODS

We conducted a systematic search of relevant databases according to pre-defined criteria. Studies were eligible for inclusion if they employed MABIs for patients diagnosed with anxiety disorders.

RESULTS

Nineteen eligible studies were found. Meta-analysis of within-group pre- to post-treatment effects yielded overall Hedges'g effect sizes of 1.08 for anxiety symptoms and 0.85 for depression symptoms. For controlled studies, overall between-group Hedges'g was 0.83 for anxiety symptoms and 0.72 for depression symptoms. Moderator analyses examined whether intervention type, design, treatment dosage, or patient sample was associated with systematic variation in effect sizes. No significant moderating effects were found on the variables examined, apart from an observed superiority in effect size for clinical trials on samples of patients with mixed anxiety disorders. However, differential effect sizes indicated benefits of adding specific psychotherapeutic content to mindfulness training, as well as an advantage of individual over group treatment.

CONCLUSIONS

MABIs are associated with robust and substantial reductions in symptoms of anxiety and comorbid depressive symptoms. More research is needed to determine the efficacy of MABIs relative to current treatments of choice, and to clarify the contribution of processes of mindfulness and acceptance to observed outcome.

A Case of Premature Termination in a Treatment for Generalized Anxiety Disorder

In this paper we present a case of failure in an integrative treatment for generalized anxiety disorder (GAD) combining cognitive-behavioral therapy, an empirically supported treatment for GAD, and interpersonal-emotional processing therapy. The client of focus dropped out of treatment after the eighth session. Based on our analysis of this case, we discuss the participant, technical and relationship factors that were likely implicated in this case of premature termination in both of the cognitive-behavioral and interpersonal-emotional processing segments that comprised the treatment. Implications for practice, training and future research are also discussed.

The role of values-consistent behavior in generalized anxiety disorder

BACKGROUND

Theory and research suggest that generalized anxiety disorder (GAD) is associated with diminished quality of life and restriction in valued action. The purpose of this study was to examine the relevance of values-consistent behavior (valued action) in understanding the impairment in quality of life in GAD.

METHOD

Treatment-seeking clients with a principal diagnosis of GAD (n = 30) were compared with demographically matched nonanxious controls (n = 30) using self-report measures.

RESULTS

Participants with GAD reported significantly less valued action compared with controls, and within the GAD group, diminished valued action was not fully explained by depression comorbidity. Valued action was significantly correlated with measures of experiential avoidance, distress about emotions, and quality of life. Further, consistent with a theoretical model of GAD, restrictions in valued action contributed unique variance to diminished quality of life over and above the contributions of gender, GAD severity, experiential avoidance, distress about emotions, and depression comorbidity. Finally, an acceptance-based behavioral therapy significantly improved self-reports of valued action for GAD clients with 40% achieving clinically significant change in this domain.

CONCLUSION

The findings provide preliminary support for the relevance of valued action in understanding the functional impairment associated with GAD, and the beneficial effects of an acceptance-based behavior therapy in increasing valued action.

An Acceptance-Based Behavioral Therapy for Individuals with Generalized Anxiety Disorder

In response to clinical observations and research findings that individuals with Generalized Anxiety Disorder are reactive to their internal experiences, avoid and suppress painful emotions, thoughts, and sensations, and limit their involvement in meaningful activities, an Acceptance Based Behavioral Therapy (ABBT) was developed to specifically target these responses. ABBT incorporates acceptance and mindfulness strategies with more traditional behavior therapy techniques. Specifically, ABBT uses mindfulness and acceptance approaches as an alternate response to the rigid, avoidant responses characteristic of GAD. Likewise, therapy focuses on identifying and enacting behaviors that are congruent with what is personally meaningful to the client rather than engaging in actions that are motivated by avoidance of anxiety. This article provides a case conceptualization from an ABBT perspective for "William," the composite client presented in Robichaud (this issue). The article goes on to demonstrate how an ABBT approach to treatment may unfold session-by-session for "William."

The potential impact of mindfulness on exposure and extinction learning in anxiety disorders

Mindfulness based approaches have shown promise in the treatment of various anxiety disorders. However, further research is needed to more precisely elucidate mechanisms of action through which mindfulness practice may enhance treatment for anxiety. Given centrality of exposure-based procedures in the treatment of anxiety, it is important to consider ways in which mindfulness may affect exposure and extinction processes. In fact, numerous findings in the basic science of extinction point to the possible ways in which mindfulness may facilitate extinction learning. The present paper aims to critically review the literature surrounding mindfulness and extinction learning in order to more fully explore the ways in which mindfulness-based treatments may positively impact exposure and extinction processes in the treatment of anxiety disorders. This will provide a unique synthesis of newer, acceptance-based behavior therapies with established principles of effective behavioral treatments.

Treatment of Three Anxiety Disorder Cases With Acceptance and Commitment Therapy in a Private Practice

Acceptance and commitment therapy (ACT) for anxiety disorders is a type of cognitive behavioral therapy that focuses on decreasing the behavior regulatory function of anxiety and related cognitions, and has a strong focus on behavior change that is consistent with client values. In this case series, 3 consecutive referrals seeking treatment for anxiety disorders at a private practice were treated with 9–13 sessions of ACT. In-session exposure therapy was not included to determine the effects of ACT without the compounding effects of already proven treatment procedures. The treatment procedure was identical across disorders to test the use of a unified treatment protocol for anxiety disorders: panic disorder with agoraphobia, comorbid social phobia and generalized anxiety disorder, and posttraumatic stress disorder. All participants showed clinical improvement in their specific anxiety disorders as rated on multiple standardized assessments after treatment, with gains maintained at follow-up (8 months or more). Time series assessments, taken throughout treatment, of anxiety and avoidance behaviors showed large decreases in avoidance but not in anxiety, suggesting ACT was effective by changing the way participants responded to anxiety rather than anxiety itself.
