title: Dyadic associations between psychological distress and sleep disturbance among Chinese patients with cancer and their spouses.
abstract: Patients with cancer and their spouses usually both suffer, but the dyadic effects have not been thoroughly investigated. This study examined the dyadic effects of psychological distress on sleep disturbance in Chinese couples affected by cancer.
  
  
  
  Patients with cancer and their spouses (N = 135) participated in this study. The Hospital Anxiety and Depression Scale and Pittsburgh Sleep Quality Index were used to measure anxiety, depression, and sleep disturbance.
  
  
  
  There were significant patient-spouse associations on anxiety (r = 0.48, P < .01), depression (r = 0.55, P < .01), and sleep disturbance (r = 0.30, P < .01). Analyses using the actor-partner interdependence model showed that anxiety had significant actor effects, rather than partner effects, on sleep disturbance in both patients and their spouses, but depression had both actor and partner effects. In addition to providing evidence for the concordance in distress and sleep disturbance in patients with cancer and their spouses, the findings indicate a mutual influence of depression on sleep disturbance among the couples.
  
  
  
  Clinicians and health care providers are suggested to integrate depression management as a component of sleep therapies and involve both patients and their spouses in treatment programs.
