Psychological inflexibility as a predictor associated with insomnia.

Psychological flexibility has recently attracted the attention of researchers in the field of sleep disorders; therefore, in the study, psychological flexibility was evaluated as a predictor or factor related to the presence/severity of insomnia. We included 2218 individuals selected from the randomized-control trial for behavioural therapy for insomnia and cross-sectional studies, including 1797 individuals with insomnia and 421 controls without insomnia. All participants completed the DSM-5-based insomnia diagnosis interview, Insomnia Severity Index, Hospital Anxiety and Depression Scale, and Acceptance Action Questionnaire-II.

A systematic review with meta-analyses of the relationship between recurrent binge eating and sleep parameters.

Methods: We conducted a systematic review with meta-analyses examining the relationship between binge eating and sleep parameters.
