Comparison between St Mary's Hospital Sleep and Richards-Campbell Sleep Questionnaires on Sleep Quality in Patients with Acute Coronary Syndrome

Researchers use various questionnaires to examine the sleep of patients admitted to intensive care units. This study carried out aiming to compare between Richards-Campbell Sleep Questionnaire and St Mary's Hospital Sleep Questionnaire in order to assess the sleep quality in patients with acute coronary syndrome hospitalized in CCU ward.

The present study was performed as a descriptive correlational study on 72 patients with acute coronary syndrome admitted to CCU of Vali-e-Asr Hospital in Qom from May 2017 to July 2018. In addition to demographic characteristics, sleep quality was assessed using Richards-Campbell Sleep Questionnaire and St Mary's Hospital Sleep Questionnaire, and psychometric properties of the two tools, were evaluated by the COSMIN Checklist. The correlation between the scores of two questionnaires was assessed using Spearman’s correlation coefficient.

In this study, 72 patients (72.2% male and 27.28% female) with the mean age of 59.59±1.17 (age range, 32-78 years) were studied. The COSMIN Checklist did not show all psychometric properties in both questionnaires and the correlation coefficient of the two questionnaires was weak (r=-0.44, p=0.23).

The results of the present study showed that both Richards-Campbell Sleep Questionnaire and St Mary's Hospital Sleep Questionnaire are suitable for evaluation of the quality of sleep, but due to their high use in different studies, more researches are needed to be performed on these two questionnaires in order to determine all of their psychometric dimensions.
