Response variability of salivary cortisol among older adults under psychological stress.
In this study, a quasi-experimental design with repeated measures was used to compare anxious (n = 129) and nonanxious (n = 186) older adults on the cortisol secretion rate attributable to an experimental stressor. Our results support the hypothesis that a first-order longitudinal factor model appropriately describes the cortisol concentration in three saliva samples collected at two experimental times. The model tested explained between 82.6 and 98.0% of the variance in cortisol concentration of the respondent's saliva samples at T1, and between 55.4% and 78.4% at T2. ⋯ By contrast, in the anxious group (STAI >or= 42), our results showed no significant gradient in the magnitude of the cortisol reactivity at either time. This result was interpreted to be in agreement with the helplessness reaction hypothesis. These results suggest that salivary cortisol is a valid measure that is sensitive to experimental stress, and may therefore, be useful in examining physiological response to stress.

The balance of care: reconfiguring services for older people with mental health problems.
The belief that most older people, including those with complex needs, can, and would prefer to be, cared for in their own homes underpins community care policy in many developed nations. There is thus a common desire to avoid the unnecessary or inappropriate placement of older people in care homes or in hospital by shifting the balance of provision. This paper demonstrates the utility of a 'balance of care' approach to address these issues in the context of commissioners' intention to reconfigure services for older people with mental health problems in a defined geographical area of the North West of England. The findings suggest that, if enhanced community services were available, a number of people currently admitted to residential or hospital beds could be more appropriately supported in their own homes at a cost that is no greater than local agencies currently incur.

Happiness and congruence in older adulthood: a structural model of life satisfaction.
The purpose of this study was to determine how health impairment, socioeconomic status, and social support relate to life satisfaction in later life. Using data from a sample of 320 older adults from The Georgia Centenarian Study, we constructed a structural model of life satisfaction. LISREL analysis was performed to test a two-factor model that included Happiness and Congruence and to determine the relationship of health impairment, socioeconomic status (SES), and social support to Happiness and Congruence, two measures of the Life Satisfaction Index-A (LSI-A). ⋯ Findings also support a relationship between social resources and subjective well-being in later life. In particular, the association between social resources and life satisfaction was mediated through health impairment. These findings offer understanding relative to how health and social resources influence past and present assessments of subjective well-being among the elderly.

Bereavement after caregiving or unexpected death: effects on elderly spouses.
Responses to bereavement have been shown to vary depending on whether death is expected or unexpected, and on the nature of family caregiving experiences, but little previous research has examined these factors simultaneously. To address these issues, we utilized prospective data on bereavement from 193 participants in the Changing Lives of Older Couples (CLOC) study, who were assessed both before their loss and at six and 18 months after the death. ⋯ All groups except highly stressed caregivers showed improvements in social activity and support after bereavement, suggesting that highly stressed caregivers may be at an increased risk for social isolation during bereavement. Thus experiencing an unexpected death may put bereaved spouses at risk for depression, while high-stress caregiving may lead to problems with social isolation.

The purpose of this study was to examine factors associated with life satisfaction in the oldest-old within a spectrum of psychosocial and health related variables. Scores on the life satisfaction index (LSI-Z) were related to scales and questions regarding, demographics, depression, locus of control, cognitive function, functional capacity (instrumental and personal activities of daily living), self-rated overall health and medically based health, and social network. The sample consisted of 315 participants, aged 80-98 years; (M = 83 years, 66% women). ⋯ However, there were different patterns of variables associated with life satisfaction in men and women. Self-rated overall health and depressive symptoms were related to life satisfaction in women, whereas widowhood was significantly associated with lower life satisfaction among men. The results emphasize the need to analyse associates of life satisfaction within a broader context of psychosocial variables and separately for men and women.
