Two studies of the relationship between pain and negative affect are presented in this article: a study of weekly fluctuations in pain and negative affect among those with arthritis and a study of daily fluctuations in pain and negative affect for participants with fibromyalgia. The roles of positive affect and mood clarity (or the ability to distinguish(More)
We describe a program of research examining how the relationship between positive and negative affect varies both between individuals and within individuals over time. This Dynamic Model of Affect (DMA) proposes that under conditions that promote maximal information processing, positive and negative affective systems function relatively independently. In(More)
