The present study examines the possibility that a chronic pain condition, such as fibromyalgia, was associated with deficits in decision making and associative learning. ⋯ These findings indicate that pain and depressive symptoms in fibromyalgia might lead to significant deficits in emotionally charged cognitive tasks. Furthermore, it suggests that chronic pain might impose a high cost on executive control, undermining mainly affective processes involved in learning, memory, attention, and decision-making.

Medically unexplained symptoms (MUSs) are a humanitarian and economic burden. Among them, pain complaints without organic pathology are the most prevalent. Theoretically, activated illness-related memory may cause reporting of symptoms by changing perception and interpretation of bodily signals to the extent that they are not tolerated and become complaints. We tested whether activating illness-related memory without conscious awareness leads to decreased pain tolerance (PT). ⋯ The findings suggest that PT can be involuntarily decreased by activating illness-related memory. This implies partial evidence for a crucial element of a cognitive model of medically unexplained symptoms, which holds that chronically activated illness-related memory causes the development of somatic complaints without observable bodily pathology.

The objective of this work was to examine the relationship between illness perception, health status, and health-related quality of life (HRQOL) in a cohort of adults with cystic fibrosis (CF). ⋯ Adults with CF report a high understanding of their disease, feel that CF has significant consequences, and endorse both personal and treatment control over their outcomes. Illness perceptions did not vary with increased age or worsening disease severity, suggesting that illness perceptions may develop during adolescence. Illness perceptions were associated with psychosocial, but not physical, aspects of HRQOL. Efforts to modify illness perceptions as part of routine clinical care and counseling may lead to improved quality of life for adults with CF.

This study involves a comprehensive investigation of autonomic cardiovascular regulation in fibromyalgia syndrome (FMS) at rest and during painful stimulation and its association with pain indices. ⋯ The data suggest impaired autonomic cardiovascular regulation in FMS in terms of reduced sympathetic and parasympathetic influences, as well as blunted sympathetic reactivity to acute stress. The association between baroreflex function and pain experience reflects the pain inhibition mediated by the baroreceptor system. Given the reduced baroreflex sensitivity in FMS, one may assume deficient ascending pain inhibition arising from the cardiovascular system, which may contribute to the exaggerated pain sensitivity of FMS.

Attentional bias to emotion- and illness-related information plays a prominent role in many mental disorders, particularly major depressive disorder and anxiety disorders. Using the emotional Stroop task we investigated which variables beyond aspects of patients' psychopathology might influence reaction times and interference in the Stroop test. ⋯ The present study provides further support for the idea that the experience of childhood trauma influences adult neuropsychological performance. Furthermore, the findings suggest that the ability to suppress emotions may be an important predictor of attentional bias.
