Among psychological inflexibility processes, only experiential avoidance, cognitive fusion, acceptance and value-based actions were found to predict insomnia severity.
“with insomnia severity (Paulos-Guarnieri et al., 2023), only experiential avoidance (McCracken et al., 2021; Zakiei et al., 2022), cognitive fusion (McCracken et al., 2022; McCracken et al., 2023), acceptance (Daly-Eichenhardt et al., 2016; Zakiei et al., 2022) and value-based actions (McCracken et al., 2021) were found to predict insomnia severity.”

Psychological inflexibility may be a transdiagnostic factor underlying sleep problems.

In Zakiei et al. (2022), all PI measures were associated with both sleep measures (ISI and PSQI).

In Zakiei et al. (2022), experiential avoidance was the strongest predictor for both sleep outcomes.
“regression‐based analysis found that experiential avoidance was the strongest predictor for both outcomes.”

In Zakiei et al. (2022), values and limited perspective taking were not significant in the models.
“Present moment awareness, cognitive fusion and inaction were also significant in these models, but values and limited perspective taking were not.”

That inaction did not uniquely relate to sleep quality was inconsistent with the Zakiei et al. (2022) findings and with two studies examining sleep in chronic pain patients, which showed committed action was related to sleep outcomes.

From Associations between psychological inflexibility processes, pre‐sleep arousal and sleep quality. (2025) · cites this paper as Zakiei et al., 2022
All measured PI processes (cognitive fusion, experiential avoidance, limited perspective-taking, lack of present moment awareness and inaction) were moderately to strongly related to sleep quality, such that increased PI processes were associated with decreased sleep quality.
“In line with predictions and previous research (Zakiei et al., 2022), all measured PI processes (cognitive fusion, experiential avoidance, limited perspective‐taking, lack of present moment awareness and inaction) were moderately to strongly related to sleep quality, such that increased PI processes were associated with decreased sleep quality.”

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.
