Executive functioning independently predicts self-rated health and improvement in self-rated health over time among community-dwelling older adults.

OBJECTIVES: Self-rated health, as distinct from objective measures of health, is a clinically informative metric among older adults. The purpose of our study was to examine the cognitive and psychosocial factors associated with self-rated health. METHODS: 624 participants over the age of 60 were assessed at baseline, and of these, 510 were contacted for a follow-up two years later. Measures of executive function and self-rated health were assessed at baseline, and self-rated health was assessed at follow-up. We employed multiple linear regression analyses to investigate the relationship between executive functioning and self-rated health, while controlling for demographic, psychosocial and biological variables. RESULTS: Controlling for other relevant variables, executive functioning independently and solely predicted self-rated health, both at a cross-sectional level, and also over time. Loneliness was also found to cross-sectionally predict self-rated health, although this relationship was not present at a longitudinal level. CONCLUSION: Older adults' self-rated health may be related to their executive functioning and to their loneliness. Self-rated health appeared to improve over time, and the extent of this improvement was also related to executive functioning at baseline. Self-rated health may be a judgement made of one's functioning, especially executive functioning, which changes with age and therefore may be particularly salient in the reflections of older adults.

Perceiving emotion in crowds: the role of dynamic body postures on the perception of emotion in crowded scenes.

Although the perception of emotion in individuals is an important social skill, very little is known about how emotion is determined from a crowd of individuals. We investigated the perception of emotion in scenes of crowds populated by dynamic characters each expressing an emotion. Facial expressions were masked in these characters and emotion was conveyed using body motion and posture only. We systematically varied the proportion of characters in each scene depicting one of two emotions and participants were required to categorise the overall emotion of the crowd. In Experiment 1, we found that the perception of emotions in a crowd is efficient even with relatively brief exposures of the crowd stimuli. Furthermore, the emotion of a crowd was generally determined by the relative proportions of characters conveying it, although we also found that some emotions dominated perception. In Experiment 2, we found that an increase in crowd size was not associated with a relative decrease in the efficiency with which the emotion was categorised. Our findings suggest that body motion is an important social cue in perceiving the emotion of crowds and have implications for our understanding of how we perceive social information from groups.

Perceived health status is associated with hours of exercise per week in older adults independent of physical health.

BACKGROUND: Perceived health status does not always reflect actual health status. We investigated the association between objective and self-rated measures of health status and hours of exercise per week in older adults. METHOD: As part of the TRIL clinic assessment, we gathered information from 473 community dwelling adults over the age of 65, regarding hours spent per week exercising, depression, personality, perceived health status, and objective health status (in the form of a comorbidity count). Regression analyses were performed on these data to investigate whether perceived health status, objective health status, personality and mood are associated with hours of exercise per week. RESULTS: Perceived and objective health status were significantly but weakly correlated. Both perceived and objective health status, as well as depression, were independently associated with hours of exercise per week. CONCLUSIONS: We conclude that exercise uptake in older adults is contingent on both perceived and objective health status, as well as depression. Perceived health status has a stronger association with exercise uptake in older adults with lower depression levels. The current findings have implications for designing exercise interventions for older adults.

Teleconferencing as a source of social support for older spousal caregivers: initial explorations and recommendations for future research.

Teleconferencing is increasingly being used as a medium of delivering social support for dementia caregivers. Further direction is required from pilot studies before the optimal clinical service can be delivered. Following a 6-week pilot support group for spousal caregivers, delivered via teleconferencing software, we interviewed 8 participants for their feedback. Semi-structured interviews were conducted and analyzed using grounded theory analysis. Themes of "group processes" and "barriers," containing subcategories of "functions of the group," "responsibilities of facilitators," and "barriers to communication" were discussed. According to caregivers, successful teleconferencing support groups should acknowledge the caregiver as the dementia expert, allow participants to meet before the deployment of the support group, provide active facilitation and leadership via the researcher, employ user-friendly technologies, and facilitate for the group to self-maintain following the pilot deployment period. These issues should be taken into consideration when designing future teleconferencing applications for caregivers.
