Acceptance and Commitment Therapy-Specific Processes in the Psychotherapeutic Treatment of Obsessive Compulsive Disorder: A Single Case Study

Abstract

This single case study describes acceptance and commitment therapy (ACT) with exposure and response prevention (ERP) used with a client presenting with symptoms of obsessive compulsive disorder (OCD). Standardized and idiographic outcome measures, including OCDspecific measures (Brief Yale-Brown Obsessive Compulsive Scale; Obsessional Compulsive Inventory), general measures of well-being and risk (CORE Outcome Measure; Outcome Rating Scale), an idiographic measure (Easy Personal Questionnaire), and a Sessional Rating Scale, were used across baseline and treatment phases. Statistical measures of reliable and clinical change were calculated, and client perspective on change was sought through interview. Cause-effect analysis was used to evaluate the extent to which therapeutic change was due to ACT-specific processes. Results showed reliable positive change with a probability of p < .05 across measures, and clinical change in three of five of the measures in which it could be calculated. The client reported improvements in well-being and the extent to which she lives her life according to her values. ACT-specific processes as well as generic therapy processes influenced change. The client's own strengths and personal contributions to therapy played a major role in her achievement of therapeutic goals. The use of ACT with ERP in treating OCD and collaborative use of outcome measures with careful evaluation are recommended to clinicians.

“…Y-BOCS puanlarında güvenilir olumlu bir değişim olduğu belirlenmiştir. Ayrıca katılımcı iyi oluşunda da düzelmeler olduğunu bildirmiştir (Wheeler 2017). SSRI tedavisi gören OKB tanılı hastaların tedavisine grup KKT'yi eklemenin etkilerini incelemek amacıyla yapılan araştırmada; tedavi sonrasında her iki koşulda da Y-BOCS ve BDÖ-II puanlarında anlamlı azalmalar olduğu ancak takipte SSRI ile birlikte KKT koşulundaki anlamlı azalmaların daha fazla olduğu belirlenmiştir.…”

Acceptance and Commitment Therapy as a Transdiagnostic Approach to Treatment of Behavioral Health Concerns: A Concurrent Multiple Baseline Design Across Participants

“…To date, a plethora of empirical support exists for both the efficacy and process of change in ACT as a unified treatment for a multitude of behavioral health concerns (Atkins et al, 2017;Bloy et al, 2011;Levin et al, 2012). ACT has also been investigated extensively using single-case methodology (e.g., Bogusch et al, 2018;Boynton-Wheeler, 2017), which allows for an in-depth examination of the process of change and trajectory of relevant variables throughout treatment. One way to contribute to this literature is to continue to extend an in-depth analysis of both therapeutic processes and outcomes of ACT using a within-subject experimental design, a paradigm commonly used in previous research (e.g., Hill et al, 2014;Knowlton et al, 2019).…”

Cognitive Behavioral Therapy for Foreign Accent Syndrome: A Single-Case Experimental Design

“…The SRS comprises four analog 10-cm scales, exploring (a) relationship , (b) goals , (c) approach , and (d) client’s perception of the session . The maximum score of 40 indicates the highest therapeutic alliance (Wheeler, 2017). The SRS is considered to be a valid and reliable measure of the therapeutic alliance (α = .88, Duncan et al, 2003).…”
