This study examined the relative efficacy of intensive versus weekly cognitive-behavioral therapy (CBT) for adults with obsessive-compulsive disorder (OCD). Sixty-two adults with OCD received either 14 sessions of weekly (n=30) or intensive CBT (n=32; daily psychotherapy sessions) in a non-randomized format. Assessments were conducted at Pre-treatment, Post-treatment, and 3-month Follow-up by raters who were blind to treatment group at the Pre-treatment assessment. Intensive and weekly CBT were similar in efficacy at Post-treatment and Follow-up and associated with large treatment effect sizes. Since many people with OCD do not have access to trained CBT providers, intensive treatment may be a viable option in such cases.

    • "Cognitive– behavioral therapy research has similarly examined the effect of session frequency on outcome and has found that in addition to affecting the amount of recovery, frequency may affect the speed of recovery. For example, in a comparison of obsessive– compulsive disorder treatment administered either daily (for 14 days) or weekly (for 14 weeks), therapeutic effects seemed to be equally effective, even at a 3-month follow-up (Storch et al., 2008; see also Emmelkamp, van Linden van den Heuvell, Rüphan, & Sanderman, 1989). If these two approaches are indeed equivalent in effect, the more frequent treatment facilitates a faster recovery for the patient. "

    ABSTRACT: Objective: The dose-response relationship in psychotherapy has been examined extensively, but few studies have included session frequency as a component of psychotherapy "dose." Studies that have examined session frequency have indicated that it may affect both the speed and the amount of recovery. No studies were found examining the clinical significance of this construct in a naturalistic setting, which is the aim of the current study. Method: Using an archival database of session-by-session Outcome Questionnaire 45 (OQ-45) measures over 17 years, change trajectories of 21,488 university counseling center clients (54.9% female, 85.0% White, mean age = 22.5) were examined using multilevel modeling, including session frequency at the occasion level. Of these clients, subgroups that attended therapy approximately weekly or fortnightly were compared to each other for differences in speed of recovery (using multilevel Cox regression) and clinically significant change (using multilevel logistic regression). Results: Results indicated that more frequent therapy was associated with steeper recovery curves (Cohen's f2 = 0.07; an effect size between small and medium). When comparing weekly and fortnightly groups, clinically significant gains were achieved faster for those attending weekly sessions; however, few significant differences were found between groups in total amount of change in therapy. Conclusions: Findings replicated previous session frequency literature and supported a clinically significant effect, where higher session frequency resulted in faster recovery. Session frequency appears to be an impactful component in delivering more efficient psychotherapy, and it is important to consider in individual treatment planning, institutional policy, and future research.

    • "In this study of 40 patients, intensive and weekly treatments were associated with equivalent decreases in the Children's Yale-Brown Obsessive Compulsive Scale (CY-BOCS; m ¼15.7 and 15.6, respectively). Similarly, in the largest study of intensive OCD treatment to date, Storch et al. (2008) found that a similar percentage of adults no longer met the criteria for OCD following a 3-week intensive treatment, 40.7%, and weekly treatment, 52.3%. Despite the success of these intensive programs, a three-to fourweek treatment protocol places a considerable burden on families staying away from home. "

    ABSTRACT: This study extends support for a 5-day intensive exposure and response prevention (ERP) treatment protocol for pediatric obsessive compulsive disorder (OCD). Twenty-two children with OCD received ERP treatment twice daily for 5 days. The treatment also emphasized teaching children and parents how to conduct ERP independently after they returned home. Symptoms were assessed at four time-points: Baseline, 4 weeks later at pre-treatment, one week after the intensive treatment 5-day treatment, and at 3 month follow-up. Changes on the primary outcome measure, clinician severity ratings on the Anxiety Disorders Interview Schedule for Children, and secondary measures, indicated that OCD symptoms remained stable from the evaluation to baseline and improved significantly from baseline to follow-up. Moreover, parental accommodation of OCD decreased significantly from baseline to post-treatment and from post-treatment to follow-up. These data suggest that the 5-day intervention demonstrates efficacy in reducing OCD symptoms and may initiate change in parent accommodation that continues to improve after the family returns home.

    • "These intensive interventions tend to provide many of the same cognitive behavioral skills included in traditional weekly therapies, although they are provided across a highly condensed time. Preliminary evidence generated through the conduct of single case designs and small opentrial evaluations suggests that interventions such as these are promising and are associated with significant reductions in the severity of the anxiety disorder diagnoses targeted in treatment (Deacon & Abramowitz, 2006; Storch, et al., 2007) as well as patient-rated comorbid anxious and depressive symptomatology (e.g., Storch, et al., 2008). More recently, Ollendick and colleagues (2010) investigated the impact of comorbidity on a one session Specific Phobia treatment as well as the impact of the treatment on comorbid disorders. "

    ABSTRACT: Previous research findings have shown positive effects of cognitive-behavioral therapy for primary anxiety disorders as well as for nonprimary, co-occurring anxiety disorders. In this study, we analyzed data from an existing randomized controlled trial of intensive treatment for panic disorder with or without agoraphobia (PDA) to examine the effects of the treatment on comorbid psychiatric diagnoses. The overall frequency and severity of aggregated comorbid diagnoses decreased in a group of adolescents who received an 8-day treatment for PDA. Results suggest that an 8-day treatment for PDA can alleviate the symptoms of some specific comorbid clinical diagnoses; in particular specific phobias, generalized anxiety disorder, and social phobia. These findings suggest that an intensive treatment for PDA is associated with reductions in comorbid symptoms even though disorders other than PDA are not specific treatment targets.
