Perceived Stress and Sleep Quality among Chinese Drug Users: Analysis of Rumination as a Mediator and Resilience as a Moderator

This study aimed to explore the relationship between perceived stress and sleep quality among Chinese drug users while considering rumination as a mediator and resilience as a moderator. Measuring scales, including the Connor –Davidson Resilience Scale, the Ruminative Response Scale, the Perceived Stress Scale, and the Pittsburg Sleep Quality Index, were used to collect information from 104 Chinese drug users. The mediating analysis documented that the effect of perceived stress on sleep quality was mediated via rumina tion significantly. Resilience acts as a significant moderator on the relationship between perceived stress and poor sleep quality. Simple slope analysis further suggests that participants with a low level of resilience experienced more sleep disturbances given the same level of perceived stress com pared to those with a high level of resilience. These findings indicated that psychological intervention that improves drug users’ resilience and reduces their rumination is helpful to release their stress and improve their sleep quality.
