The current review proposes a relationship among pain, self-regulatory capacity, self-regulatory demands, executive functions, and self-regulatory fatigue, suggesting that executive functions and self-regulatory deficits are indeed part of the etiology and maintenance of chronic pain conditions.
Research suggests individuals possess multifaceted cognitive representations of various diseases. These illness representations consist of various beliefs, including causal attributions for the disease, and are believed to motivate, guide, and shape health-related behavior. As little research has examined factors associated with beliefs about cancer causation, the present study examined the relationship between personal and family history of cancer and beliefs about the causes and prevention of malignant disease. Data was obtained from 6369 adult respondents to the 2003 Health Information National Trends Survey (HINTS), a national population-based survey. Information about personal and family history of cancer and beliefs regarding cancer causation and prevention was obtained. Results showed both a personal and family history of cancer were associated with differences in beliefs about the causes of cancer. In general, a personal history of cancer was not significantly linked to causal attributions for cancer relative to those without a personal history. In contrast, a family history of cancer tended to increase the likelihood a respondent viewed a particular cause as increasing cancer risk. Thus, personal and vicarious experience with cancer had dramatically diverging influences on attributions of cancer causation, which may be due to differing self-protection motives. Results support the belief that illness representations, in this case the causal belief component, are influenced by both personal and vicarious experience with a disease and also suggest illness representations may influence receptivity to messages and interventions designed to increase appropriate cancer risk reduction behavior.
Repetitive thought (RT) involves frequent or prolonged thoughts about oneself and one's world, encompassing discrete forms such as trait worry, rumination, processing, and reminiscing. These forms of RT can be described using three basic, underlying qualities: total propensity for RT of all types, valence (positive versus negative content), and purpose (searching or uncertainty versus solving or certainty). The adaptiveness of discrete forms with regard to health is likely to be related to these qualities, particularly valence and total propensity. The present study confirmed the model and identified the relationship of these qualities of RT to subjective psychological, physical, and cognitive health in older adults aged 60-94 (N = 179). As predicted, more negatively valenced trait RT was associated with worse psychological, physical, and cognitive health. More total propensity for RT was associated only with worse psychological health. Searching purpose was associated only with worse cognitive health. In turn, negatively valenced RT was predicted by poorer executive functions, suggesting that such functions may be important for directing this quality of RT. The valence of older adults' RT is important insofar as it may contribute to their sense of good or ill health. However, the propensity for all kinds of RT to associate with poorer psychological health may reflect the co-occurrence of negative and positive RT, such as rumination and emotional processing. Although RT has not been extensively investigated in older adults, it appears to play an important role in their subjective health. Keywordsworry; rumination; processing; health; executive functions Repetitive thought (RT), defined as "the process of thinking attentively, repetitively, or frequently about oneself and one's world" is an important determinant of psychological and physical well-being (Segerstrom, Stanton, Alden, & Shortridge, 2003, p. 909). Forms of RT such as worry and rumination both contemporaneously and prospectively increase negative mood states such as anxiety and depression and dysregulate physiological systems such as the cardiovascular and immune systems (e.g., Kubzansky, Kawachi, Spiro, Weiss, Vokonas, & Sparrow, 1997;Nolen-Hoeksema, 1991;Nolen-Hoeksema & Morrow, 1991;Pieper, Correspondence should be addressed to Suzanne C.

Low QOL among ALS patients is likely due to pre-existing individual differences, whereas both individual differences such as demographics (e.g., age) and disease progression are likely to affect QOL among caregivers.
