Associations between psychological inflexibility processes, pre-sleep arousal and sleep quality.
Article in Psychology and psychotherapy, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 8 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectivesPsychological inflexibility, the model of psychopathology underlying Acceptance and Commitment Therapy (ACT), has been linked to a broad range of psychological problems, but its link with sleep quality is not well understood. This study aimed to identify relationships between psychological inflexibility processes (cognitive fusion, experiential avoidance, limited perspective-taking, lack of present moment awareness and inaction) and sleep quality, investigating pre-sleep arousal and anxiety symptomatology as mechanisms mediating these relationships.
designA correlational, cross-sectional design was used to test two statistical models.
methodsParticipants (N = 704) from a general population sample completed an online survey, reporting on sleep quality, pre-sleep arousal, anxiety and measures of psychological inflexibility. Data were analysed using correlations and path analyses.
resultsAll psychological inflexibility processes were moderate to strongly correlated with sleep quality. Path analysis showed cognitive fusion, lack of present moment awareness and experiential avoidance, mediated by pre-sleep cognitive and somatic arousal, explained 49% of the variance in sleep quality (Model 1). Cognitive fusion via pre-sleep cognitive arousal had the largest effect. Anxiety preceding pre-sleep arousal (Model 2) explained no additional variance, and model fit was poorer than Model 1.
conclusionsThese findings highlight the role of psychological inflexibility processes in disrupting the de-arousal process needed for healthy sleep, supporting evidence for ACT as a treatment for sleep disturbance.
