Associations of Perceived Stress, Resilience and Social Support with Sleep Disturbance Among Community-dwelling Adults.

Sleep disturbance is often described as sleeping poorly, difficulty falling asleep and maintaining sleep, and waking early. Currently, most studies examining sleep disturbance have focused on negative psychological variables; however, few studies have combined both negative and positive psychosocial factors to assess sleep. The aim of this study was to investigate the prevalence of sleep disturbance and psychosocial correlates in Chinese community-dwelling adults. A total of 1471 adults, between 18 and 60 years old, from eight selected community settings in Jinan, China, were surveyed using the Pittsburgh Sleep Quality Index, Perceived Stress Scale, 10-item Connor-Davidson Resilience Scale and Multidimensional Scale of Perceived Social Support and provided sociodemographic information. We found that the prevalence of sleep disturbance was 33.9%. After adjusting for age, employment status and physical co-morbidity, perceived stress was significantly associated with sleep disturbance [odds ratio (OR)=1.14, p<0.001], while resilience and social support were associated with a low likelihood of sleep disturbance (OR=0.90, p<0.001; OR=0.97, p<0.001). Furthermore, regression analysis showed that the interaction between perceived stress and resilience was significant (p<0.05). Resilience buffered the negative impact of perceived stress on sleep disturbance. Given the close relationship between sleep disturbance and psychosocial correlates, the development of effective intervention programmes to improve sleep quality in this population should be considered.
