Psychological Mechanisms of Effective Cognitive–Behavioral Treatments for PTSD

Abstract

Several psychotherapies have been established as effective treatments for posttraumatic stress disorder (PTSD) including prolonged exposure, cognitive processing therapy, and cognitive therapy for PTSD. Understanding the key mechanisms of these treatments, i.e., how these treatments lead to therapeutic benefits, will enable us to maximize the efficacy, effectiveness, and efficiency of these therapies. This article provides an overview of the theorized mechanisms for each of these treatments, reviews the recent empirical evidence on psychological mechanisms of these treatments, discusses the ongoing debates in the field, and provides recommendations for future research. Few studies to date have examined whether changes in purported treatment mechanisms predict subsequent changes in treatment outcomes. Future clinical trials examining treatments for PTSD should use study designs that enable researchers to establish the temporal precedence of change in treatment mechanisms prior to symptom reduction. Moreover, further research is needed that explores the links between specific treatment components, underlying change mechanisms, and treatment outcomes.

  • Negative responses to trauma disclosure are likely to reinforce negative beliefs about oneself, others, and the world, which are thought to play a critical role in the aetiology and maintenance of PTSD symptoms.

    “Negative responses to trauma disclosure are likely to reinforce negative beliefs about oneself, others, and the world, which are thought to play a critical role in the aetiology and maintenance of PTSD symptoms (see Zalta, 2015 for a review).”

    From The association between social support and posttraumatic stress symptoms among survivors of betrayal trauma: a meta-analysis (2021) · cites this paper as Zalta, 2015

    In “Theorized Psychological Mechanisms of CBT Treatments for PTSD” (page unavailable), Zalta reviews models in which negative beliefs about oneself, others, and the world contribute to PTSD symptoms and their maintenance. The review also notes that others’ reactions may be perceived as rejecting or blaming, but it does not establish that negative responses to trauma disclosure reinforce those beliefs.

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.

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.
