title: Development and Validation of Sleep Disturbance Questionnaire in Patients with Acute Coronary Syndrome.
abstract: Background and Objectives. Severe sleep disturbance is a common problem among patients in cardiac care units (CCUs). There are questionnaires to measure sleep disturbances. Therefore, the present study seeks to design a valid and reliable questionnaire to assess sleep disturbance in patients with acute coronary syndrome (ACS) hospitalized in CCUs. Materials and Methods. In the present methodological research, items of the questionnaire were extracted through a systematic review. The validity and reliability of the questionnaires was assessed by face validity, content validity, construct validity, Cronbach's alpha coefficient, and test-retest methods. Results. Factor analysis provided a questionnaire of 23 items on 5 dimensions of sleep disturbance in coronary patients: "sleep onset and continuity disorder," "disorder in daytime functioning," "sleep disturbance caused by environmental factors," "sleep disturbance as a result of cardiac diseases," and "respiratory disorders during sleep." Furthermore, test-retest analysis showed a reliability correlation coefficient of r = 0.766 and α Cronbach's reliability (α = 0.855). Conclusion. Sleep disturbance questionnaire for patients with ACS hospitalized in coronary care unit (CCU) was identified in 5 dimensions and assessed for validity and reliability. To control and improve the sleep quality of CCU hospitalized patients, we need to identify and remove predisposing factors.
