Abstract:
Sleep disturbances are common complaints in individuals with psychiatric disabilities, frequently occurring at onset and with exacerbation of illness. A small descriptive study of community-based overweight individuals (N = 9) completed the Pittsburgh Sleep Quality Index, wore an ActiGraph and kept a sleep diary for 7 to 14 days. All but two participants had poor sleep efficiency based on actigraphy scores, an objective measure of sleep. These scores were in agreement with the Pittsburgh Sleep Quality Index, a self-report measure, in all but one participant. The findings indicate the Pittsburgh Sleep Quality Index is a comprehensive measure to use in assessing sleep in individuals who have psychiatric disabilities.
