Abstract

Objective: The purpose of this study was to examine decentering as a potential mechanism of action across 2 treatments for generalized anxiety disorder: an acceptance-based behavioral therapy (ABBT) and applied relaxation (AR). Method: Sixty-four individuals who completed at least half of the 16 total sessions of either ABBT or AR (65.6% female; 79.7% identified as White; average age =34.41 years) completed measures of decentering (Experiences Questionnaire) and of symptoms of anxiety (Depression Anxiety Stress Scale-Stress subscale) at 5 time points over the course of therapy, and a measure of worry (Penn State Worry Questionnaire) at pre- and posttreatment. Results: Initial growth curve models showed that decentering increased significantly over therapy (z =7.09), and this increase was associated with a decrease in worry symptoms (Penn State Worry Questionnaire) at posttreatment (z = -8.51). The rate of change did not significantly vary across treatments, Δ χ2/Δdf =0.16/1, p =.69. Further, a series of bivariate latent difference score models indicated that the best-fitting model was one in which decentering was a leading indicator of change in symptoms (DASS-Stress). Allowing this coupling to vary across treatments did not significantly improve the fit of the model, Δ χ2/Δdf = 0.71/1, p =.40. Conclusions: In this sample, results suggest that increased decentering was associated with decreases in anxiety and that changes in decentering appear to precede changes in symptoms within both ABBT and AR, indicating that decentering may be an important common mechanism of action. © 2015 American Psychological Association.

    Model 2, with only the coupling from decentering to anxiety, was an equivalent fitting model to the full bidirectional model (p = .15), indicating the anxiety-to-decentering coupling did not significantly improve the model and could be removed.

    “The non-significant chi-square difference test (p = .15) indicates that the more parsimonious Model 2 was an equivalent fitting model to the full Model, indicating that the coupling from anxiety to decentering does not significantly add to the model and can be dropped leaving the couplings from decentering to symptoms.”

    The latent difference score model's coupling parameter reflects a causal influence of decentering on symptoms rather than reverse causation or confounding.

    “the best fitting model was one in which decentering was a leading indicator of change in symptoms (DASS-Stress).”
  • The authors state this as an assumption.

    In the bivariate latent difference score model, the coupling parameter stands for one variable's effect on change in the other.

    “It is this coupling parameter that represents the influence of one variable on change in the second variable.”
  • The authors state this as an assumption.

    Latent change scores equal the initial-state score plus all accumulated latent changes to that point.

    “These latent change scores are based on the score at the initial state plus all latent changes that have accumulated up to that point.”
  • The authors state this as an assumption.

    A bivariate model adds prior scores of the other variable to the accumulated change in the focal variable.

    “In a bivariate model, in addition to the accumulated change on the variable of interest, previous scores of a second variable are also included.”
  • The authors state this as an assumption.

    Each latent variable depends on three parts: the linear slope, the focal variable's prior score, and the other variable's prior score.

    “Each of these latent variables are a function of three components: 1) the linear slope or average rate of change in the given variable, α; 2) the previous score of the variable of interest, β; and 3) the score of the other variable at the previous time point, γ, which is typically referred to as the coupling parameter.”
  • The authors state this as an assumption.

    A chi-square difference test between nested models indicates whether freeing a parameter significantly improves fit.

    “The chi-square difference between these two nested models provides information regarding whether or not allowing the parameter of interest to vary significantly adds to the model fit.”

    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 [82]

    The cited paper does not report greater increases in decentering for ACT than for relaxation training. Its Abstract Results report that decentering increased, but the rate of change did not significantly differ between the treatments studied: acceptance-based behavioral therapy (ABBT) and applied relaxation (AR). The Present Study section identifies those treatments; ACT was not a treatment arm. (LLM, conf=0.88)

    Checked by a reasoning model — may be wrong.

  • In Hayes-Skelton and colleagues' study, decentering was a common mediator across acceptance-based behavior therapy and applied relaxation; decentering increased in both conditions and predicted better symptom outcomes.

    “Decentering was found to be a common mediator across both treatment conditions. Decentering significantly increased across both treatment conditions, and this increase predicted better symptom outcomes.”

    The Results report a significant increase in decentering, an association with reduced worry symptoms, and no significant difference in its rate of change between acceptance-based behavioral therapy and applied relaxation. The Discussion also reports that changes in decentering preceded changes in anxiety symptoms across treatments. However, the authors describe these findings as support for a potential common mechanism, not as establishing decentering as a common mediator. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • Some prior studies have found that metacognitive abilities mediate outcomes in other cognitive behavioral therapies for generalized anxiety disorder.

    “A few studies thus far have demonstrated a mediating role for these metacognitive abilities in other cognitive behavioral therapies (CBTs) for GAD.”

    From Changes in Decentering and Reappraisal Temporally Precede Symptom Reduction During Emotion Regulation Therapy for Generalized Anxiety Disorder With and Without Co-Occurring Depression. (2019) · cites this paper as Hayes-Skelton et al., 2015

    The Discussion reports that, in this study of GAD, changes in decentering preceded changes in anxiety symptoms across acceptance-based behavioral therapy and applied relaxation. But the paper does not establish that a few prior studies demonstrated mediation in CBTs specifically for GAD: its discussion of a prior ACT-versus-CBT mediation finding concerns anxiety disorders more broadly, and it says decentering had not been systematically examined as a treatment mechanism for GAD. (LLM, conf=0.85)

    Experimental — accuracy not yet measured
  • In a secondary analysis of the same RCT, decentering was a common mechanism of change across ABBT and AR.

    “A recent secondary data analysis from the same RCT as the current study, comparing ABBT and Applied Relaxation (AR) in a sample with GAD found decentering to be a common mechanism of change across both treatment conditions (Hayes-Skelton, Calloway, Roemer, & Orsillo, 2015).”

    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 Hayes-Skelton, Calloway, Roemer, & Orsillo, 2015

    The Present Study section identifies this as an analysis of data from an RCT comparing ABBT and AR in people with GAD. The Results and Discussion report a similar relationship between decentering and later anxiety symptoms across both treatments, but describe this as support for a *potential* common mechanism, not a definitive finding that the mechanism was established. (LLM, conf=0.84)

  • EQ scores improve over the course of behavioural and cognitive therapies, and the magnitude of such change is associated with key outcomes like symptom severity and quality of life.

    “Finally, EQ scores improve over the course of behavioural and cognitive therapies; the magnitude of such change is associated with key outcomes like symptom severity and quality of life.23 26 27 36 37”

    From Protocol for a randomised controlled trial investigating an intervention to boost decentering in response to distressing mental experiences during adolescence: the decentering in adolescence study (DECADES) (2022) · cites this paper as [26]

    The Results section (page unavailable) reports that EQ-decentering scores increased during treatment and that greater increases were strongly associated with lower post-treatment worry scores. The study examined acceptance-based behavioral therapy and applied relaxation, not cognitive therapy, and the passages found do not report an association with quality of life. (LLM, conf=0.88)

  • Conflicting claims about evidence for a gradient

    Minor

    The discussion says this study demonstrates a gradient relationship, then says future research is needed to explicitly address the gradient component. It is unclear whether the authors consider that criterion addressed by this study.

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 by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-09-28.

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