title: The effects of daily mood and couple interactions on the sleep quality of older adults with chronic pain.
abstract: We examined the effect of daily negative and positive mood on the sleep quality of knee osteoarthritis (OA) patients (N = 152) and whether a partner's daily responses to a patient's pain behaviors moderated these associations. Patients and their partners completed a baseline interview and 22 daily diary assessments. After controlling for demographic characteristics, OA severity, comorbidities, medication use, relationship satisfaction, and depressed mood, multilevel modeling analyses demonstrated main effects of negative and positive mood on sleep quality indicators. Mood and partner responses interacted such that high solicitous and punishing responses strengthened the association between negative mood and worse sleep. Further, high solicitous responses increased the degree of association between low positive mood and poor sleep, and empathic responses combined with positive mood were associated with better sleep. Results demonstrate that daily negative and positive mood fluctuations can interact with partner responses to affect sleep quality among older adults with chronic pain.
