BackgroundAlthough a relationship between mood and pain has been established cross-sectionally, little research has examined this relationship using momentary within-person data.
PurposeWe examined whether baseline depressive symptoms and within-person levels of negative and positive mood predicted momentary pain among 31 individuals with rheumatoid arthritis (RA).
MethodsDepressive symptomatology was measured at baseline. Mood and RA symptoms were self-reported via ecological momentary assessment five times a day for seven consecutive days. Analyses controlled for gender, age, weekend day, time of day, and experiences of stress.
ResultsGreater momentary positive mood was associated with less momentary pain and fewer arthritis-related restrictions; negative mood was associated with more restrictions. Greater depressive symptomatology also predicted more pain and restrictions, an effect which was not accounted for by mood.
ConclusionsResults suggest that both depression and mood are uniquely associated with momentary pain; as such, multi-component interventions may provide optimal disease management.
