Abstract

Objectives: Psychological 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.

Design: A correlational, cross-sectional design was used to test two statistical models.

Methods: Participants (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.

Results: All 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.

Conclusions: These 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.

期刊介绍： Psychology and Psychotherapy: Theory Research and Practice (formerly The British Journal of Medical Psychology) is an international scientific journal with a focus on the psychological and social processes that underlie the development and improvement of psychological problems and mental wellbeing, including: theoretical and research development in the understanding of cognitive and emotional factors in psychological problems; behaviour and relationships; vulnerability to, adjustment to, assessment of, and recovery (assisted or otherwise) from psychological distresses; psychological therapies with a focus on understanding the processes which affect outcomes where mental health is concerned.
