Sleep disturbances are associated with reduced health-related quality of life in XXXX with substance use disorders.

@entity1 @entity25
BACKGROUND AND OBJECTIVES: Sleep problems and substance use are strongly linked. Sleep problems play a role in the etiology of substance use, but also may be a result of it. After detoxification, @entity25 may worsen leading to relapse. Nowadays, most substance dependence treatment programs aim at recovery rather than total abstinence, and in that view health-related quality of life (HRQL) is a relevant construct. This article describes the association between self-perceived @entity25 and HRQL in a naturalistic population of polydrug-using inpatients. METHODS: At the start of treatment, 388 polydrug-using inpatients completed questionnaires concerning their sleep quality and HRQL. Three categories were established based on reported @entity25 : @entity1 without @entity25 (21.6%), those with clinically relevant @entity25 (34.5%), and @entity1 with @entity25 (43.8%). RESULTS: Mean grades for quality of sleep were M   =   7.3 (sd 1.7), M   =   6.6 (sd 1.7) and M   =   5.3 (sd 1.9) for the three categories, respectively. In addition, @entity1 in the disorder category perceived a lower HRQL than those in the other categories. In the explanation of HRQL, both @entity25 and @entity25 added significantly to the model when controlling for baseline characteristics. DISCUSSION AND CONCLUSIONS: Our findings stress the need for clinicians to pay attention to the quality of sleep of recovering polydrug users, since this may play an important role in the recovery process. Monitoring sleep during treatment is advocated. This study adds to the knowledge about the way HRQL and sleep are related in a naturalistic sample of substance-dependent @entity1 .
