Poor sleep quality in family caregivers may impact their health status and cause quality of life to decline. Nurses are conducting an increasing number of studies that use sleep quality or related concepts as a main indicator to assess caregiver’s sleep. Therefore, a clear understanding of sleep quality and how it is different from other relevant sleep domains is essential. This article aimed to analyze the concept of sleep quality using the steps outlined by Walker and Avant. Findings include (a) attributes of sleep quality including subjective perception of sleep, sleep hours, and evaluation of activity after awaking; (b) antecedents of sleep quality including the ability to get naturally into the sleep cycle and status of conscious state; and (c) consequences of sleep quality including bio-psycho-social and global dimensions of health. This article intends to help clinicians and researchers better understand and define sleep quality in dementia caregivers.
