PERSON AND CONTEXTUAL FEATURES OF DAILY STRESS REACTIVITY - INDIVIDUAL-DIFFERENCES IN RELATIONS OF UNDESIRABLE DAILY EVENTS WITH MOOD DISTURBANCE AND CHRONIC PAIN INTENSITY

We examined the mood-related and pain-related consequences of daily st ressors among 74 individuals with rheumatoid arthritis who supplied da ily reports for 75 days. Meta-analyses of time series regression coeff icients disclosed a significant same-day relation between events and m ood but no consistent effects of events on same-day pain, next-day moo d, or next-day pain. With distributional characteristics of the daily data controlled, Ss with more active inflammatory disease showed a gre ater positive relation of events with same-day and next-day pain, thos e with a recent history of more major life stressors showed a greater positive relation of events with next-day pain, and those with less so cial support showed a greater positive relation of events with next-da y mood disturbance. Implications of these and other findings for theor ies of stress and adaptation and the methodological challenges of dail y experience research are discussed.
