Optimism and Pain Interference in Aging Women.

BACKGROUND: Pain interferes with people's daily lives and often limits the extent to which they can pursue goals and engage in activities that promote well-being. However, people vary in how much interference they experience at a given level of pain.
PURPOSE: The present study tested how optimism affects and is affected by pain interference and goal-directed activity among older women.
METHODS: Every 3 months for 2 years, community-dwelling middle- and older-age women (N = 199) completed online daily diaries at home for a 7 day period, in which they reported their daily pain, pain interference, and goal-directed activity. Optimism was measured at the start and end of the study. Multilevel models tested the between- and within-person relationships among pain, optimism, and pain interference or goal-directed activity. Linear regression predicted change in optimism over 2 years from pain interference and goal-directed activity.
RESULTS: Pain best predicted pain interference and optimism best predicted goal-directed activity. There were subtle interactions between optimism and pain-predicting interference and goal-directed activity. Accumulated goal-directed activity and pain interference across the study predicted longitudinal changes in optimism, with higher activity and lower pain interference predicting increased optimism over 2 years.
CONCLUSIONS: Optimism may play a protective role in disruptions caused by pain on a day-to-day basis, leading to increased goal-directed activity and possibly decreased pain interference. In turn, less interference and more goal-directed activity feed forward into increased optimism, resulting in a virtuous cycle that enhances optimism and well-being among older women. © Society of Behavioral Medicine 2019.
