    The Roles of Intrusive Visual Imagery and Verbal Thoughts in Pre-Sleep Arousal of Patients With Insomnia Disorder: a Path Model

    Purpose Researchers have proposed that multiple factors such as hyperarousal, conditioning, worrying, or cortical arousal play roles in the predisposition to, initiation, and perpetuation of insomnia disorder. Previously, only a few studies investigated the differential effects of intrusive visual imagery (IVI) and intrusive verbal thoughts (IVT) on pre-sleep arousal or insomnia severity. The aim of the current cross-sectional study was to examine these effects as well as the moderator role of visual imagery ability (VIA) on the relationship between IVI and pre-sleep arousal.Methods A path model comprising the variables of IVI, IVT, pre-sleep arousal, and insomnia severity was tested with 166 of 1444 participants (M-age = 25.5, SD = 5.26) who were identified as having insomnia disorder based on a 12-question form corresponding to DSM-5 criteria for insomnia disorder and Insomnia Severity Index scores (>= 8). The moderator role of VIA on the relationship between IVI and pre-sleep arousal was evaluated with a moderation analysis.Results It was found that IVI (beta = 0.44, p < .001), but not IVT (beta = 0.15, p = .12), significantly predicted pre-sleep arousal and pre-sleep arousal (beta = 0.44, p < .001) significantly predicted insomnia severity. In addition, the indirect effect of IVI via pre-sleep arousal (IE = 0.19, p < .001) on insomnia severity was significant. Finally, the moderator role of VIA on the relationship between IVI and pre-sleep arousal (p = .07) was not significant.Conclusions IVI may play a more important role in insomnia disorder than IVT. Interventions targeting pre-sleep visual imagery can help poor sleepers alleviate insomnia severity.

    The psychometric properties of the Turkish version of the Pre-sleep Arousal Scale
    (Springer Japan Kk, 2024) Turkarslan, Kutlu Kagan; Canel cinarbas, Deniz; Nicassio, Perry M.
    PurposeThe aim of the present study was to examine the psychometric properties of the Turkish version of the Pre-sleep Arousal Scale (PSAS), which measures pre-sleep arousal, a significant predictor of insomnia symptoms.Methods651 participants were recruited via social media and the Internet. Confirmatory factor analysis was conducted in the total sample (65.28% females; M-age1 = 28.09 & PLUSMN; 14.00). Convergent, divergent, incremental, and known-groups validity and internal consistency coefficients were assessed in a subsample of 556 participants (62.77% females; M-age2 = 29.25 & PLUSMN; 14.81). A second separate sample of 88 participants (80.68% females; M-age3 = 22.19 & PLUSMN; 4.98) was used to evaluate three-week test-retest reliability.ResultsThe results of factor analysis confirmed the two-factor structure of the Turkish PSAS with cognitive (PSAS-C) and somatic (PSAS-S), similar to the original scale. The correlations of the PSAS with convergent and divergent measures showed that the Turkish form had good convergent and acceptable divergent validity. PSAS-C and PSAS-S were able to explain an 18% additional variance in insomnia severity beyond depression and anxiety, an 18% additional variance in depression beyond insomnia severity, and a 35% additional variance in anxiety beyond insomnia severity. Moreover, insomnia patients had significantly higher PSAS-C and PSAS-S scores than good sleepers. Finally, the PSAS, PSAS-C, and PSAS-S had satisfactory internal consistency coefficients (& alpha; = 0.92, 0.91, and 0.86, respectively) and three-week test-retest correlations (ICC = 0.82, 0.82, and 0.71, respectively).ConclusionThe Turkish form of the PSAS was a valid and reliable measure of pre-sleep arousal and can be utilized in sleep studies.
