    • Abstract:
      Background: Determining the self-efficacy perceptions of obstructive sleep apnea (OSA) patients has a key role in health care practices. With further evaluation, the Self-Efficacy Measure for Sleep Apnea (SEMSA) could serve as a useful scale to develop specific interventions to increase self-efficacy in patients with OSA during the acceptance and maintenance of continuous positive airway pressure (CPAP) therapy.
      Objective: The aim of this study is to translate the SEMSA into Turkish and to evaluate the psychometric properties of the translation.
      Methods: This cross-sectional study was carried out with a sample of patients recently diagnosed with CPAP-naïve OSA. Linguistic and content validity of the scale were evaluated, while exploratory factor analysis and 2-level confirmatory factor analysis were used for validity. Internal consistency and test-retest methods were used in reliability analyses.
      Results: The mean (SD) age of the patients with OSA was 51.36 (11.29), and 68% were male. The item factor loads obtained as a result of the confirmatory factor analysis ranged from 0.44 to 0.94, confirming the three-factor structure of the instrument. The Cronbach's α coefficient of the scale was found to be 0.90. Measurements made within the scope of test-retest analysis were found to be related and consistent results were obtained in the intervening time ( P  < .01).
      Conclusions: In this study, the Turkish version of SEMSA was found to be a valid and reliable tool and it could be used to evaluate the adherence-related cognition in Turkish patients with OSA on CPAP therapy.
