Balancing parent care with other roles: interrole conflict of adult daughter caregivers.

This study examined interrole conflict experienced by 278 women who simultaneously occupied 4 roles: parent care provider, mother to children at home, wife, and employee. Compared with women who experienced no conflict between parent care and their other roles, women reporting parent care conflict tended to have fewer socio-economic resources, to have older children, and to be caring for parents with greater impairment. Women who reported conflicts between parent care and employment were older; had more education; had marriages of longer duration; and had older, more self-sufficient children than women who reported conflict between the parent care role and the mother role. Some evidence was found for the hypothesis that interrole conflict between parent care and other roles mediates the relationship between parent care stress and psychosocial well-being. Results suggest that one way parent care stress exerts its deleterious effects on the well-being of adult daughters is through the incompatible pressures of parent care and other roles.

Depressive symptomatology in middle-aged and older married couples: a dyadic analysis.

OBJECTIVES: Depressive symptomatology has been frequently conceptualized as an individual matter, but social contextual models argue that symptom levels are likely to covary in close relationships. The present study investigated correlation between spouses' depressive symptomatology in middle-aged and older married couples, the influence of gender and race/ethnicity in predicting variability in symptom level, and the importance of individual-level covariates (education, health, and age) and couple-level covariates (household income and net worth). METHODS: Results were based on secondary analysis of Wave 1 interviews with White, Black, and Mexican American married couples (N = 5,423) from the Health and Retirement Study (HRS) and the Study of Asset and Health Dynamics Among the Oldest Old (AHEAD). Dyadic data from husbands and wives were analyzed with multilevel modeling. RESULTS: Husbands' and wives' depressive symptoms were moderately correlated, gender and race/ethnicity (and their interaction) predicted depressive symptoms, and both individual-level and couple-level characteristics were significant covariates. Similarities as well as differences are noted between the HRS and AHEAD results. DISCUSSION: Results highlight the importance of dyadic data and multilevel models for understanding depressive symptomatology in married couples. The influence of race/ethnicity merits greater attention in future research. Differences in findings between HRS and AHEAD suggest life-course, cohort, or methodological influences.

Centrality of women's multiple roles: beneficial and detrimental consequences for psychological well-being.

Theorists have proposed that greater centrality (personal importance) of a social role is associated with better psychological well-being but that role centrality exacerbates the negative effects of stress in that same social role on well-being. The present study found evidence to support both hypotheses in a sample of 296 women who simultaneously occupied the roles of parent care provider, mother, wife, and employee. Greater centrality of all four roles was related to better psychological well-being. As predicted, wife centrality exacerbated the effects of wife stress on life satisfaction, and employee centrality exacerbated the effects of employee stress on depressive symptoms. Contrary to prediction, centrality of the mother role buffered women from the negative effects of mother stress on depressive symptoms. These findings point to an aspect of role identity that can benefit well-being but that has complex effects in the context of role stress.

Comparisons of African American and White women in the parent care role.

Little is known about African American women's experiences providing care to impaired older relatives. This study investigated potential differences in depressive symptomatology, parent care stress and rewards, parent care mastery, and the quality of the parent care relationship between 261 White and 56 African American daughters and daughters-in-law who were providing care for an impaired parent or parent-in-law. Multivariate analysis of variance, controlling for significant background characteristics and interrelationships among caregiving experiences, revealed that African American women reported less stress and more rewards in the parent care role than White women did. Race did not have a significant effect on caregivers' depressive symptomatology, parent care mastery, or the quality of their relationship with the parent. However, this research demonstrates the importance of examining a broad range of caregiving experiences in order to detect both similarities and differences between African American and White caregivers.

Longitudinal patterns of risk for depression in dementia caregivers: objective and subjective primary stress as predictors.

The present study examined how patterns of risk for depression over 1 year in 188 dementia caregivers (consistently asymptomatic, n = 88; consistently symptomatic, n = 40; changing risk, n = 60) could be predicted by objective (behavior problems of the relative) and subjective (role captivity and overload) primary stress. Results reveal that all primary stressors differentiated caregivers who remained at low levels of symptomatology over the course of 1 year from those who were at risk for experiencing a depressive disorder. In addition, caregivers' subjective experience of role captivity predicted the chronicity of risk. Findings extend prior caregiving research on patterns of depressive symptomatology by highlighting the relationship between subjective primary stressors and stability and change in caregivers' mental health.

Mastery in women's multiple roles and well-being: adult daughters providing care to impaired parents.

The current study focused on 296 adult daughter caregivers who were simultaneously providing care to an impaired parent, mothers to children living at home, wives, and employees. How mastery (perceived competence and control) in each of these 4 roles was related to well-being was examined. Women experienced higher levels of mastery in the employee role than in any other role. After controlling for household income and dispositional optimism, only employee mastery contributed unique variance to physical health, but mastery in each of the 4 roles contributed unique variance to either depression or life satisfaction. Results also suggest that women's satisfaction with life was related to an accumulation of mastery across roles. The study expands previous research by revealing that mastery in women's additional roles can supplement the benefits of mastery stemming from parent care.

Self-esteem as a mediator between spousal support and depressive symptoms: a comparison of healthy individuals and individuals coping with arthritis.

This study examined whether self-esteem mediated the effects of both self-reported positive and negative marital interactions on depressive symptoms and whether the relationships among marital interactions, self-esteem, and depressive symptoms were stronger for individuals (n = 90) coping with arthritis compared with individuals (n = 90) not coping with a chronic illness. Data were drawn from the 1986 Americans' Changing Lives national survey. The results of multigroup structural equation analysis suggest that mediation depends on the type of marital interaction being considered and the group being examined. For the arthritis group, self-esteem mediated the relationship between negative marital interactions and depressive symptoms, whereas for the healthy group self-esteem played no role in mediating the relationship between marital interactions and depressive symptoms. Findings underscore the importance of testing moderated-mediation models of social support.

Emotional support and well-being of midlife women: role-specific mastery as a mediational mechanism.

This study examined the relationships among emotional support, mastery, and well-being for 258 women who simultaneously occupied the roles of wife, mother, parent care provider, and employee. Its primary aim was to determine if a greater sense of mastery in each of these 4 roles could explain the relationship between emotional support from the partner or partners in the same role (the husband, children, impaired parent, or work supervisor) and better psychological well-being (less depressive symptomatology and more life satisfaction). Findings revealed that more emotional support from each of the 4 role partners was related to a greater sense of mastery in that same role. Furthermore, for each of the roles of wife, mother, and employee, role-specific mastery was a mediating mechanism in the relationship between support from the role partner or partners and better well-being.

Stress of parent care: positive and negative effects of women's other roles.

The present study focused on 296 women who were primary caregivers to an ill or disabled parent or parent-in-law and who simultaneously occupied 3 other roles as mother, wife, and employee. All women lived in separate households from their impaired parent and had at least 1 child 25 years of age or younger living at home. It was predicted that stress in the roles of mother, wife, and employee would exacerbate the effects of stress in the parent care role on psychological well-being (depression and life satisfaction) and that rewards in these 3 additional roles would buffer the effects of parent care stress. For all 3 additional roles, findings supported the stress exacerbation hypothesis. In contrast, only the employee role supported the stress-buffering hypothesis. These findings underscore the complex relationships that often exist between women's multiple role experiences and their psychological well-being.

Binding ties: closeness and conflict in adult children's caregiving relationships.

The authors used a path model to test the hypothesis that emotional closeness and conflict between adult-child caregivers (N = 90) and their impaired parents mediated the impact of the parents' functional and cognitive impairment on the caregivers' subjective stress, subjective effectiveness, and depression. Closeness mediated the relationship between cognitive impairment and both stress and effectiveness, whereas conflict mediated cognitive impairment for all 3 outcomes and generally accounted for more variance. There was limited evidence that functional impairment was mediated by the quality of the relationship. Results highlight the importance of both positive and negative ties as intervening mechanisms influencing caregivers' well-being, especially in the presence of cognitive dysfunction.

Stress and rewards in women's multiple roles: the case of women in the middle.

This research examined stress and rewards experienced by 95 women who were simultaneously occupying the roles of caregiver, mother, and wife. The study examined role-specific stress and rewards as predictors of well-being (physical health, positive affect, negative affect, and role overload) and examined the effects of an accumulation of role stress and role rewards across these 3 roles. Role rewards contributed unique variance to well-being, even after role stress had been considered. An accumulation of role stress across roles was related to poorer well-being, whereas an accumulation of role rewards was related to better well-being. Findings indicated that caregivers' experiences in multiple roles could both detract from and enhance their mental and physical health.

Care-related stress. A comparison of spouse and adult-child caregivers in shared and separate households.

This research examines the role that relationship and household arrangement have in explaining the levels of care-related stress effects experienced by spouse and adult-child caregivers in shared and separate residences. Data from 180 spouse and adult-child caregivers were analyzed to identify differences in caregiver health decline, relationship strain, and activity restriction across these settings when the effects of elder impairment, caregiver age, and use of social supports are controlled. Results show that spouse and adult children in shared households experience similar levels of care-related strain. However, comparison of adult children in shared and separate households show considerable cross-setting differences in strain, with those in shared households having significantly greater activity restriction but less relationship strain. These findings have implications for the delivery of social services, specifically for targeting health monitoring, respite, and family counseling services.

Intergenerational perspectives on impaired elders' support networks.

The purpose of this paper was to compare impaired elders' and their adult children's reports of the elders' caregiving and decision-making support networks. The two generations (n = 101 each) generally agreed on the primary person in each network and on the overall hierarchy of sources of support, but they differed on the two networks' size, specific composition, and members' relative centrality. Decision-making networks were consistently smaller, more highly centralized, and more restricted to immediate family, suggesting the need to distinguish this network from the general caregiving network. Our discussion focuses on possible explanations for intergenerational differences in perspectives on elders' social support and on the desirability of taking these differences into account in both research and practice.

Fine structure of a radiation-induced osteogenic sarcoma.

An osteogenic sarcoma arose in the right orbit of a 7-year-old boy some 5 years after the right orbit had been treated by four courses of radiotherapy (total dose approximately 13,000 rads) for a multicentric retinoblastoma. Death occurred 6 months after the orbital tumor was first detected. Study of the orbital tumor by electron microscopy revealed a cell population of varied morphology in which two main types were identified. In one group, the cells were large with radiolucent cytoplasm, which contained long branching segments of rough endoplasmic reticulum. In the second group, the cells were smaller with irregular nuclei and an electron-dense cytoplasm, which contained short segments of dilated rough endoplasmic reticulum and numerous mitochondria. The first group of cells closely resembled osteoblasts, while the second group had some features of osteoclasts or their percursors. The branching processes of the tumor cells were separated by an amorphous ground substance, which contained collagen-like fibrils and hydroxyapatite crystals. Crystal deposition was in some instances in close relation to extracellular membrane-bound vesicles.
