Abstract

Objective: Effective treatments for obsessive-compulsive disorder (OCD) exist, but additional treatment options are needed. The effectiveness of 8 sessions of acceptance and commitment therapy (ACT) for adult OCD was compared with progressive relaxation training (PRT). Method: Seventy-nine adults (61 female) diagnosed with OCD (mean age = 37 years; 89 Caucasian) participated in a randomized clinical trial of 8 sessions of ACT or PRT with no in-session exposure. The following assessments were completed at pretreatment, posttreatment, and 3-month follow-up by an assessor who was unaware of treatment conditions: Yale-Brown Obsessive Compulsive Scale (Y-BOCS), Beck Depression Inventory-II, Quality of Life Scale, Acceptance and Action Questionnaire, Thought Action Fusion Scale, and Thought Control Questionnaire. Treatment Evaluation Inventory was completed at posttreatment. Results: ACT produced greater changes at posttreatment and follow-up over PRT on OCD severity (Y-BOCS: ACT pretreatment = 24.22, posttreatment = 12.76, follow-up = 11.79; PRT pretreatment = 25.4, posttreatment = 18.67, follow-up = 16.23) and produced greater change on depression among those reporting at least mild depression before treatment. Clinically significant change in OCD severity occurred more in the ACT condition than PRT (clinical response rates: ACT posttreatment = 46-56, follow-up = 46-66; PRT posttreatment = 13-18, follow-up = 16-18). Quality of life improved in both conditions but was marginally in favor of ACT at posttreatment. Treatment refusal (2.4 ACT, 7.8 PRT) and dropout (9.8 ACT, 13.2 PRT) were low in both conditions. Conclusions: ACT is worth exploring as a treatment for OCD. © 2010 American Psychological Association.

  • Case studies, multiple-baseline studies, and a single randomized trial provide early evidence that ACT is effective for anxiety disorders.

    “Case studies, multiple-baseline treatment studies and a single randomized clinical trial provide nascent evidence that ACT is an effective treatment for anxiety disorders”

    From Randomized clinical trial of cognitive behavioral therapy (CBT) versus acceptance and commitment therapy (ACT) for mixed anxiety disorders (2012) · cites this paper as Twohig et al., 2010

    The Introduction (page not provided) describes a prior multiple-baseline study in four adults with OCD, and the Discussion (page not provided) reports that this randomized trial found greater improvement in OCD symptoms with ACT than with progressive relaxation training. The paper does not establish the claimed case-study evidence or effectiveness across anxiety disorders generally; its trial findings concern OCD. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • Some data suggest that conventional CBT and ABBT produce comparable decreases in EA.

    “On the other hand, there is some evidence that traditional CBT is as effective as ABBT in reducing EA (Arch et al., 2012b; Twohig et al., 2010), which suggests that EA could be considered as a common mechanism.”

    From Reductions in experiential avoidance as a mediator of change in symptom outcome and quality of life in acceptance-based behavior therapy and applied relaxation for generalized anxiety disorder (2016) · cites this paper as Twohig et al., 2010

    The Method’s Process Results report significant improvement on the Acceptance and Action Questionnaire in both groups and no significant difference between them from pretreatment to follow-up. But this trial compared ACT with progressive relaxation training, not traditional CBT; ACT also improved significantly more than relaxation training immediately after treatment. It therefore does not establish comparable reductions in experiential avoidance with CBT and ABBT. (LLM, conf=0.84)

  • Acceptance and commitment therapy is effective for treating OCD, as are mindfulness-based interventions.

    “ACT, of which psychological flexibility/inflexibility is a process of change, is effective for treating OCD, as are mindfulness-based interventions (Bluett et al., 2014;Chien et al., 2022;Twohig et al., 2010).”

    From A pilot study of experiencing racial microaggressions, obsessive-compulsive symptoms, and the role of psychological flexibility (2023) · cites this paper as Twohig et al., 2010

    The Discussion reports greater improvement in OCD symptoms with ACT than with progressive relaxation training, and the paper describes psychological flexibility as an ACT process. The Method section says the ACT protocol included mindfulness exercises, but the study did not evaluate mindfulness-based interventions as separate treatments for OCD, so it does not support that part of the sentence. (LLM, conf=0.87)

  • Greater increases in decentering were found across ACT relative to CBT or relaxation training, but findings are equivocal with others reporting non-significant effects of intervention-type on decentering.

    From Decentering as a core component in the psychological treatment and prevention of youth anxiety and depression: a narrative review and insight report (2021) · cites this paper as [80]

    The Method’s Process Results report greater pre-to-post improvement with ACT than with progressive relaxation training on psychological flexibility and thought-control measures. The ACT protocol describes exercises resembling decentering, but the paper does not report a decentering measure or a comparative increase in decentering itself. This verdict concerns the relaxation-training comparison; the cited paper did not compare ACT with CBT. (LLM, conf=0.77)

    The Introduction describes ACT as a theory-driven approach to anxiety, and the Primary Outcome: Y-BOCS section reports significantly greater improvement with ACT than with progressive relaxation training. But this trial studied adults with obsessive-compulsive disorder; it does not establish efficacy for treating anxiety broadly. Page numbers are unavailable in our copy. (LLM, conf=0.85)

Self-check

Percentages, sums and reported differences re-computed from the paper’s own numbers.

Each contradiction between two passages listed here was confirmed by an independent check.

  • Sample size by sex does not match reported participant total

    Major

    The abstract says 79 adults participated and 66% were female, but the participant section gives 61% women in the study. These percentages cannot both describe the same sample unless the denominator or one of the percentages is different.

  • Comorbidity percentage conflicts with diagnosis counts

    Minor

    The listed counts total 36 participants with at least one additional diagnosis, or about 46% of the 79 participants, rather than the stated 51%.

  • Two different percentages are given for female participants

    Minor

    The abstract reports 66% female participants, while the participant description reports 61% for the same study sample.

  • Thought-control test statistic has the wrong sign

    Minor

    The reported negative estimated difference divided by its positive standard error gives a negative t statistic, not the positive statistic printed for the follow-up comparison.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read under definition version 3 (extract-v3) on 2026-09-28.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-09-28.

Cited sources are checked by gpt-6-sol.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
