Abstract
Objective The purpose of this study is to examine positive affect (PA) as a factor of resilience in the relationships between pain and negative affect (NA) in a sample of patients with rheumatoid arthritis. Methods Forty-three patients (30 women; mean age, 57 years) were interviewed weekly by telephone for 8 weeks. Multilevel modeling was applied to study the within-week relationships among the variables. Results There was a Pain×PA interaction effect on NA ( β=−0.05, P<.01) indicating a weaker relationship between pain and NA in weeks with more PA. Pain ( β=0.37, P<.002), interpersonal stress ( β=2.42, P<.001), depression ( β=0.26, P<.01), average perceived stress ( β=10.80, P<.001), and also weekly PA ( β=−0.1, P<.01) had a main effect upon NA. Conclusion Positive affect is most influential in reducing NA during weeks of higher pain and may be a factor of resilience, helping patients experiencing pain fluctuations as less distressful than at lower levels of PA.
