Methods: This research was conducted on 215 patients with insomnia complaints and applied to Family Medicine, Neurology (Sleep Polyclinic), and Psychiatry outpatient clinics. Introductory Information Form, 8-item Athens Insomnia Scale, and Pittsburg Sleep Quality Index were administered to the participants. After the language adaptation of the scale, Cronbach’s alpha value was used as the consistency coefficient for reliability analysis. Exploratory factor analysis was examined for structural validity, and correlation coefficients between the Athens Insomnia Scale and its subscales and the Pittsburg Sleep Quality Index were examined for concurrent validity. Results: Cronbach’s alpha coefficient was calculated as 0.87. “Kaiser-Meyer-Olkin value was calculated for factor analysis.” In the Exploratory Factor Analysis, a two-factor structure with eigenvalues >1.0 and explaining 73.4% of the variance was obtained. According to the Exploratory Factor Analysis results for the Atina Insomnia Scale, the absolute value of the factor loadings of the eight items ranged between 0.650 and 0.865. The correlation coefficients between the total score and sub-dimensions of the Athens Insomnia Scale and the Pittsburg Sleep Quality Index-a scale assessing sleep quality were between 0.489–0.725 (p<0,01). For discriminant validity, Athens Insomnia Scale discriminated well between patients and healthy volunteers (Z=2.630, p=0,009). Conclusion: The Athens Insomnia Scale has been shown to have adequate reliability and validity in Turkish. © 2023 by Turkish Association of Neuropsychiatry-Available online at www.noropskiyatriarsivi.com.Englishadaptationadultagedanxiety disorderArticleAthens Insomnia Scaleconcurrent validitycontent validitycorrelation coefficientdemographicsdepressiondiscriminant validityDSM-5educationepilepsyexploratory factor analysisfamily historyfemalehigh schoolhumanincomeinsomniainternal consistencyinterviewlanguagemajor clinical studymalemarriageperceptionPittsburgh Sleep Quality Indexprimary schoolprincipal component analysispsychometryrank sum testreliabilitysleep qualitysociodemographicsuniversityArticle10.29399/npa.28575
