Chronic Pain and Affective Experiences Associated with Daily Stressors and Uplifts.

People with chronic pain often report greater reactivity to stress than those without pain. This finding is consistent with the kindling hypothesis, which states that continued exposure to stressors only heightens negative affect and dampens positive affect. Yet, people with chronic pain may also respond more positively to enjoyable activities, or uplifts, as well. Chronic pain is related to lower levels of well-being, and the fragility of positive affect model explains how individuals with lower levels of well-being often exhibit stronger, more positive responses to daily uplifts than their less distressed peers. Our study used the National Study of Daily Experiences to assess daily stressors, positive uplifts, and positive and negative affect across eight days among those with and without chronic pain. Participants (nChronicPain=658, nNoPain=1,075) were predominately Non-Hispanic White (91%), 56% female, and averaged 56 years old. Results revealed that people with chronic pain had lower levels of daily positive affect and higher levels of negative affect, yet the two groups did not vary in their stressor-related negative and positive affect. In contrast, having chronic pain was related to a greater increase in positive affect and greater decreases in negative affect on days with positive uplifts. Findings suggest that intervention efforts focusing on uplifts may be particularly helpful for people who report chronic pain.

Blood pressure as a predictor of everyday cognitive function in aging adults with and without fibromyalgia.

Objective : Both hypotension and hypertension are related to poorer cognitive performance in older adults. However, little attention has been paid to everyday problem solving, a real-world indicator of functionality and independence among aging individuals. Research also suggests that chronic pain may affect the relationship between blood pressure (BP) and cognition. This study examined the relationship between BP and everyday problem solving in older adults with and without fibromyalgia (FM), a chronic pain condition. Method : The study included 99 participants with an FM diagnosis (Mage = 59.95) and 88 healthy older adults (Mage = 68.01). Results : Multiple regression analyses revealed that systolic BP and pulse pressure, but not diastolic BP, were significant predictors of everyday problem solving after controlling for executive function. FM status did not moderate this relationship. Conclusion : These findings indicate that BP is an important factor in functional and cognitive health, especially among aging adults.
