Disability and depressive symptoms in the elderly: the effects of instrumental support and its subjective appraisal

Uncovering the determinants of brain functioning, behavior and their interplay in the light of context

Notwithstanding the huge progress in molecular and cellular neuroscience, our ability to understand the brain and develop effective treatments promoting mental health is still limited. This can be partially ascribed to the reductionist, deterministic and mechanistic approaches in neuroscience that struggle with the complexity of the central nervous system. Here, I introduce the Context theory of constrained systems proposing a novel role of contextual factors and genetic, molecular and neural substrates in determining brain functioning and behavior. This theory entails key conceptual implications. First, context is the main driver of behavior and mental states. Second, substrates, from genes to brain areas, have no direct causal link to complex behavioral responses as they can be combined in multiple ways to produce the same response and different responses can impinge on the same substrates. Third, context and biological substrates play distinct roles in determining behavior: context drives behavior, substrates constrain the behavioral repertoire that can be implemented. Fourth, since behavior is the interface between the central nervous system and the environment, it is a privileged level of control and orchestration of brain functioning. Such implications are illustrated through the Kitchen metaphor of the brain. This theoretical framework calls for the revision of key concepts in neuroscience and psychiatry, including causality, specificity and individuality. Moreover, at the clinical level, it proposes treatments inducing behavioral changes through contextual interventions as having the highest impact to reorganize the complexity of the human mind and to achieve a long-lasting improvement in mental health.

COVID-19: Factors Predicting Depressive Symptoms in People Aging With Long-Term Physical Disabilities

The mental health impact of the COVID-19 pandemic may be greater than that of the viral infection. This impact is likely greater for disadvantaged groups such as people with long-term physical disabilities (PwLTPD). This cross-sectional study used a multiple linear regression model to examine factors associated with depressive symptoms and to understand their relative importance during the onset of the COVID-19 pandemic. The model explained 58% of the variance in depressive symptoms. Anxiety was the most important predictor, accounting for 8% of variance. Higher levels of anxiety, loneliness, and financial stress; prior diagnosis of depression; and non-Black race predicted a higher level of depressive symptoms in PwLTPD during the onset of the COVID-19 pandemic. Occupational therapy practitioners should strategically acknowledge predictors of depression that cannot be modified and actively address those that can be modified through evidence-based interventions to improve depressive symptoms in PwLTPD.

Changes in the role of explanatory factors for socioeconomic inequalities in physical performance: a comparative study of three birth cohorts

BACKGROUND

Due to societal changes and changes in the availability of health promoting factors, explanatory factors of socioeconomic inequalities in health (SIH) may change with time. We investigate differences in the relative importance of behavioural, social and psychological factors for explaining inequalities in physical performance between three birth cohorts.

METHODS

Data came from N = 988, N = 1002, and N = 1023 adults aged 55-64 years, collected in 1992, 2002 and 2012 as part of the Longitudinal Aging Study Amsterdam. Physical performance was measured by three performance tests. We included lifestyle factors (physical activity, smoking, alcohol use and Body Mass Index (BMI)); social factors (network size, network complexity, divorce, social support); and psychological factors (mastery, self-efficacy and neuroticism). In multi-group mediation models, we tested whether the strength of indirect effects from socioeconomic position (SEP) via the explanatory factors to health differed between birth cohorts. Stronger indirect effects indicate an increase in the importance; weaker indirect effects indicate a decrease in importance.

RESULTS

Absolute SIH were present and similar across cohorts. The strength of indirect effects of SEP on physical performance through smoking, binge alcohol use, emotional support and mastery increased across cohorts. The indirect effects of BMI, network size, self-efficacy and neuroticism were similar across cohorts.

CONCLUSIONS

Inequalities in smoking, binge alcohol use, emotional support and mastery may have become more important for explaining SIH in recent cohorts of middle-aged adults. Policies that aim to reduce socioeconomic inequalities may need to adapt their targets of intervention to changing mechanisms in order to reduce SIH.

Perceived Social Support and Interpersonal Functioning as Predictors of Treatment Response Among Depressed Older Adults

OBJECTIVE

Social isolation is highly common in late life and is associated with devastating mental health and physical outcomes. This study investigated whether components of social isolation (marital status, perceived social support, and interpersonal problems) predict change in depression severity over the course of a brief adherence intervention delivered in a primary care setting.

METHOD

A sample of 189 older adults with major depressive disorder were randomized to either an adherence intervention, "Treatment Initiation Program," or treatment as usual. Marital status, perceived social support and interpersonal problems were assessed at baseline. A mixed-effects regression was used to test whether these factors predicted the change trajectory in depression severity over 24 weeks.

RESULTS

Being married (F(2,176) = 6.60; p = 0.001), reporting higher perceived social support (F(2,177) = 4.70; p = 0.01), and fewer interpersonal problems (F(2, 176) = 4.34; p = 0.01) predicted lower depression severity on average over the course of 24 weeks.

CONCLUSION

Social variables such as living in partnership, perceiving others as supportive, and reporting few interpersonal problems may reduce older adults' vulnerability to depression and enhance their ability to benefit from treatment. These findings can guide development of interventions that will target these social factors early in treatment to increase efficacy.

Psychometric properties of modified MOS social support survey 5-item (MSSS-5-item) among Iranian older adults

BACKGROUND

Social support is a key factor in public health. Since the precise evaluation of it is critical, the current study has been developed to evaluate the psychometric properties of the MOS-SSS questionnaire's abbreviated form (MSSS-5-item) among the Iranian older adults.

METHODS

This cross-sectional and methodological study was conducted on 420 community older adults (age ≥ 60) through random multi-stage sampling. The questionnaire was first translated into Persian through the Forward & Backward method based on WHO guidelines. Next, the validity of scales was investigated by calculating face validity, content validity, Known-group validity, explanatory factor analysis, and confirmatory factor analysis indices. The reliability of the questionnaire was calculated by internal consistency, test-retest, and absolute reliability. Moreover, the scalability of the questionnaire was checked through the Mokken scale analysis. The software packages SPSS version 22, AMOS version 22, and R (Mokken package) were employed to analyze the data.

RESULTS

the face validity was conducted using interviews with older adults and gathering the specialists' opinions. Then, the items were grammatically and lexically corrected accordingly. The CVI index of the overall scale was 0.94, and for every single item above 0.89. The results of the independent t-test showed that the current questionnaire well distinguished between the older adults who do and do not feel lonely (p < 0.001). Two components were recognized according to the explanatory factor analysis. They together explained 67.78% of the total variance of the questionnaire. The CFA showed that the two-factor model had acceptable fit indices. The questionnaire had desirable internal consistency (α = 0.78), stability (ICC = 0.98), and absolute reliability (SEM = 0.56, MDC = 1.57). Furthermore, the Mokken scale proved that MSSS-5-item was a strong scale (H = 0.51, se = 0.03).

CONCLUSION

The present study results showed that the MSSS-5-item questionnaire had suitable validity and reliability to be used among Iranian older adults.

Development and Testing of a Neuropsychiatric Symptoms Model in Mild Cognitive Impairment

Neuropsychiatric symptoms are prevalent in individuals with mild cognitive impairment (MCI) and have a significant detrimental effect on health and quality of life. Identifying factors that contribute to their occurrence may enable prompt treatment and intervention. The current study entails the development and testing of a biopsychosocially based model to assist nurses in the identification of individuals with MCI who are most likely to experience symptoms of depression, apathy, and/or anxiety. Factors within the biological and sociodemographic domains of the Neuropsychiatric Symptoms in MCI (NPSMCI) model were tested using multivariate logistic regression analyses. Findings suggest that age, presence of an e4 allele of the apolipoprotein E gene, living situation, and degree of comorbid illness were associated with the occurrence of symptoms of depression and apathy. Further testing and refinement are necessary, but the findings provide guidance to nurses and alert them to assess individuals most likely to experience these symptoms.

The Effect of Parent-Child Geographic Proximity on Widowed Parents’ Psychological Adjustment and Social Integration

The authors examine the ways that parent-child geographic proximity affects widowed older parents’ psychological well-being and social integration. Analyses are based on the Changing Lives of Older Couples (CLOC) study, a prospective study of 1,532 married individuals aged 65 and older. Compared with those who live more than one hour away from a child, widowed older adults who live with or live within an hour’s drive of their child(ren) report significantly lower levels of psychological distress, after controlling for parent-child relationship quality. However, parents who live with their children are less likely to be integrated into informal networks of friends, neighbors, and relatives. The findings reveal the complex ways that living arrangements and geographic proximity between generations affect bereaved parents’ psychosocial adjustment. This study also suggests ways that bereaved older adults may optimize their support networks during an era marked by high levels of geographic mobility and low fertility.

Social ties and psychological well-being in late life: the mediating role of relationship satisfaction

OBJECTIVE

The current paper examines whether quantitative aspects of social support (i.e., support network characteristics) indirectly influence psychological well-being via older adults' qualitative perceptions of support (i.e., satisfaction with social relationships).

METHODS

A sample of 416 adults aged ≥60 was drawn from the Social Integration and Aging Study, a community-based survey conducted in a small US (Midwestern) city. The survey assessed social networks, social support, and physical and mental health among older adults.

RESULTS

Bootstrapping was used to examine mediation models. Greater support network size predicted lower perceived stress, fewer depressive symptoms, and better life satisfaction, yet this association was fully mediated by relationship satisfaction. For support network composition, greater proportion kin was associated with lower stress and better life satisfaction, though not depressive symptoms, however, relationship satisfaction did not mediate this link.

DISCUSSION

Findings highlight the complex interplay of support network characteristics and satisfaction, and suggest the greater import of support satisfaction for older adults' psychological well-being.

The association between social relationships and depression: a systematic review

BACKGROUND

Depression is one of the most prevalent mental disorders globally and has implications for various aspects of everyday-life. To date, studies assessing the association between social relationships and depression have provided conflicting results. The aim of this paper was to review the evidence on associations between social relationships and depression in the general population.

METHODS

Studies investigating the association of social support, social networks, or social connectedness with depression were retrieved and summarized (searches using Pubmed, ScienceDirect, PsycNet were conducted in May 2014).

RESULTS

Fifty-one studies were included in this review. The strongest and most consistent findings were significant protective effects of perceived emotional support, perceived instrumental support, and large, diverse social networks. Little evidence was found on whether social connectedness is related to depression, as was also the case for negative interactions.

LIMITATIONS

Due to the strict inclusion criteria relating to study quality and the availability of papers in the domain of interest, the review did not capture 'gray literature' and qualitative studies.

CONCLUSION

Future research is warranted to account for potential bias introduced by the use of subjective measures as compared to objective measures of received support and actual networks. Due to the heterogeneity between available studies on the measure of social relationships, the inclusion of comparable measures across studies would allow for more valid comparisons. In addition, well-designed prospective studies will provide more insight into causality. Future research should address how social support and networks interact and together affect risks for depression. Social connectedness and negative interactions appear to be underutilized as measures in population-based studies.

Support and self-efficacy among Latino and White parents of children with ID

Research indicates that mothers of children with ID who receive familial support experience less stress than those who receive less support. Less is known about the relation of support to mothers' evaluation of parenting self-efficacy, particularly in Latino families. We examined the relationship of different types of family support to life satisfaction and parenting self-efficacy (PSE), and explored whether income and ethnicity moderated these relationships. Interviews with 84 Latino and 37 White participants revealed that partner emotional support predicted life satisfaction and PSE in both ethnic groups, with a stronger relationship evident for the PSE of Latino mothers. Income was not a significant moderator. These findings provide guidance for more effective family interventions targeted toward Latinos.

Functional impairment, illness burden, and depressive symptoms in older adults: does type of social relationship matter?

OBJECTIVE

The nature of interpersonal relationships, whether supportive or critical, may affect the association between health status and mental health outcomes. We examined the potential moderating effects of social support, as a buffer, and family criticism, as an exacerbating factor, on the association between illness burden, functional impairment and depressive symptoms.

METHODS

Our sample of 735 older adults, 65 years and older, was recruited from internal and family medicine primary care offices. Trained interviewers administered the Hamilton Rating Scale for Depression, Duke Social Support Inventory, and Family Emotional Involvement and Criticism Scale. Physician-rated assessments of health, including the Karnofsky Performance Status Scale and Cumulative Illness Rating Scale, were also completed.

RESULTS

Linear multivariable hierarchical regression results indicate that social interaction was a significant buffer, weakening the association between illness burden and depressive symptoms, whereas perceived social support buffered the relationship between functional impairment and depressive symptoms. Family criticism and instrumental social support were not significant moderators.

CONCLUSIONS

Type of medical dysfunction, whether illness or impairment, may require different therapeutic and supportive approaches. Enhancement of perceived social support, for those who are impaired, and encouragement of social interactions, for those who are ill, may be important intervention targets for treatment of depressive symptoms in older adult primary care patients.

Functional disability and psychological well-being in later life: does source of support matter?

OBJECTIVES

This study explored the buffering effects of instrumental and emotional support from different sources against the impact of increasing functional disability on depression and life satisfaction.

METHODS

Random effects modeling was utilized with data from a nationwide longitudinal study in Taiwan. A total of 6722 observations from 2856 elders over a seven-year period served as subjects of this study.

RESULTS

The results suggested that instrumental support from family members and formal organizations as well as emotional support from families, friends and formal organizations was significantly associated with better psychological well-being among the elderly in Taiwan. In addition, receiving instrumental support from family members and formal organizations can moderate the linkage between increasing functional disability and depression.

CONCLUSION

The results emphasize the importance of encouraging a partnership between natural helpers and health care professionals. A good integration between formal and informal networks could more effectively meet the needs of the frail older adults and their families. This study also calls for more attention to the cultural competence of health care policy and service delivery.

The impact of informal care-giving networks on adult children's care-giver burden

Previous research on the care-giver burden experienced by adult children has typically focused on the adult child and parent dyad. This study uses information on multiple informal care-givers and examines how characteristics of the informal care-giving network affect the adult child's care-giver burden. In 2007, 602 Dutch care-givers who were assisting their older parents reported on parental and personal characteristics, care activities, experienced burden and characteristics of other informal care-givers. A path model was applied to assess the relative impact of the informal care-giving network characteristics on the care-giver burden. An adult child experienced lower care-giver burden when the informal care-giving network size was larger, when more types of tasks were shared across the network, when care was shared for a longer period, and when the adult child had no disagreements with the other members of the network. Considering that the need for care of older parents is growing, being in an informal care-giving network will be of increasing benefit for adult children involved in long-term care. More care-givers will turn into managers of care, as they increasingly have to organise the sharing of care among informal helpers and cope with disagreements among the members of the network.

Social interactions and depressive symptoms among community dwelling older adults in Nepal: a synergic effect model

In Asian families, where patriarchal family systems are common, living arrangements of older adults are characterized by residing with a married son. This study examines the synergic effects of intergenerational solidarity (emotional and instrumental support exchange and anticipated support) on depression of older adults from a developing country, Nepal. Gender differences are also explored in the study. This was a cross-sectional face-to-face interview study of 489 community dwelling older adults living in an urban area of Nepal. The data were analyzed using multiple regression models with each dimension of intergenerational solidarity and conflict variables entered one-by-one with the confounding variables. The results illustrate that older women receiving lower emotional and instrumental support were significantly more likely to be depressed compared to older men receiving less support from their son. Also, women reporting lower anticipated support and higher conflict with their son were more likely to be depressed than men. Regarding synergic effects, emotional support exchange buffered against the deleterious effects of conflict with depression in older adults. The results highlight a need for further research on late life intergenerational relationships (IR) and mental health of older adults in developing countries so that it can be useful for health care practitioners.

Social Ties and Depression: An Intersectional Examination of Black and White Community-Dwelling Older Adults

Aging literature often links social ties to lower depression for older adults; however, research shows inconsistent findings by race and gender. Drawing from an “intersectionality” framework, this article explores whether the relationship between social ties and depression is moderated by race and gender for a nationally representative sample of diverse, community-dwelling older adults (aged 60 and older). Analysis of the most recent wave of the Health and Retirement Study (HRS) indicates that White men, Black men, White women, and Black women differ in terms of the relationship between social ties and depression. Main findings include (a) the overwhelming benefit of marriage and partnership, (b) pronounced differences between Black women’s and White women’s friend and kin ties, and (c) the potential vulnerability of older Black men. Findings highlight the importance of catering community-based elder support toward diverse aging populations. Potential community-based care solutions are discussed.

A comparison of rural and urban older adults in Iowa on specific markers of successful aging

This study examines the differences between rural and urban older adults on level of life satisfaction and depressive symptoms, focusing on the effect of social support. Data were collected through structured interviews at senior centers and senior meal sites in eastern and southeastern Iowa. The Duke Social Support Index (DSSI), the Life Satisfaction Index-Z (LSI-Z), and the Geriatric Depression Scale 15 (GDS15) were used. Correlations (Pearson's r), independent sample t-tests, and multiple regression were computed. Findings indicated that urban residents reported more depressive symptoms, as compared to rural residents. Subjective level of social support was a stronger predictor of life satisfaction and was more negatively related to depressive symptoms among rural than among urban older adults. Results suggest that social workers who work with aging people need to be aware of rural-urban differences in mental health. Furthermore, social workers need to have knowledge of older adults' social networks and work to ensure greater opportunity for social interaction.

Personality traits and perceived social support among depressed older adults

The contribution of personality traits and social support to mental health is well established, but to our knowledge there have been no longitudinal investigations of the relation between personality and social support in depressed older adults. In the current study, we examined a repeated measures multi-level mixed model of change in perceived social support to determine whether personality traits and depressive symptoms were associated with changes in perceived social support over the 3 year study interval in a sample of depressed older adults. Results suggest that Conscientiousness and Extraversion were personality traits that were significantly predictive of changes in perceived social support over this time interval. Based on these results it appears that, among depressed older adults, those with conscientious or extraverted personality traits are more likely to resist impulses to withdraw from relationships. In addition, these traits may lead to more satisfying interactions and greater perceived social support over time. The implications of these results are discussed.

Between freedom and reclusion: social support as a quality-of-life component in the family caregiver-dependent person binomial

This is a qualitative study which uses Grounded Theory as its methodological framework and Symbolic Interactionism as a theoretical base to understand the experience of family caregivers for Cerebrovascular Accident (CVA) patients with regard to social support during their rehabilitation process at home. The components (themes and categories) of the phenomenon assuming home care and specifically the themes assuming care with support and assuming care without support were inter-related for the purpose of comparison and analysis, in order to apprehend how the interaction between them occurred. It was observed that, in addition to the recovery of the patient's autonomy, social support is one of the intervenient components in the quality of life for the family caregiver-disabled person binomial, particularly with respect to the caregiver's freedom to resume his/her life plan.

The effect of widowhood on intergenerational ambivalence

OBJECTIVE

The purpose of this study was to examine (a) the extent to which widowhood affects older adults' ambivalence about their adult children, (b) the role of intergenerational dependence in explaining the effect of widowhood on parent-child ambivalence, and (c) temporal changes in the effects of widowhood on ambivalence.

METHODS

We based analyses on Changing Lives of Older Couples, a prospective study of 1,532 married individuals aged 65 and older. We used ordinary least squares regression models to estimate the direct effect of widowhood and the mediating effects of dependence on intergenerational ambivalence 6 and 18 months after spousal loss.

RESULT

Widowhood was associated with a decrease in ambivalent feelings toward adult children 6 months after spousal loss, which was partially explained by a reduction in the extent to which children were dependent upon their bereaved parents. However, at 18 months, widowhood did not exert any significant influence on intergenerational ambivalence.

DISCUSSION

Our findings suggest that major life events such as widowhood influence intergenerational ambivalence. The results shed light on the mechanisms by which parent-child dependence contributes to intergenerational ambivalence.

Aspectos estruturais e funcionais do apoio social de idosos do Município de São Paulo, Brasil

Este trabalho teve como objetivo descrever a distribuição das redes sociais e de apoio em idosos no Município de São Paulo, Brasil, por características sócio-econômicas e demográficas. Estudou-se amostra probabilística de 1.568 idosos (60 ou mais anos) da cidade de São Paulo (inquérito sobre Saúde, Bem-estar e Envelhecimento - SABE), focalizando-se as dimensões estruturais e funcionais das redes sociais. Para a análise dos dados utilizou-se a regressão logística simples e múltipla. As melhores condições nas redes sociais foram observadas nos menores patamares de renda e as piores entre os mais velhos e os "não casados". Para as mulheres, as chances de estarem "não casadas" aumentaram significativamente quanto pior era o seu nível educacional. O "status de coabitação" foi o que mais influenciou o apoio funcional, onde "morar só" aumentou significativamente as chances de não ocorrerem as trocas sociais. Os modelos de regressão logística múltipla construídos separadamente por gênero sugerem que idade, estado civil, renda per capita e escolaridade estão associados com as redes sociais entre os idosos. No entanto, essas relações manifestam-se de modos desiguais entre gêneros e entre as características sócio-demográficas para as diferentes dimensões da rede social.

Stress buffering effects of social support on depressive symptoms in middle age: reciprocity and community mental health

Little is known about the association between depression and the buffering effects of social support in mid-life crisis. The aim of this study is to determine the buffering effects of social support on depression concerning middle-aged individuals, while also taking reciprocity and gender differences into careful consideration. A cross-sectional survey of all middle-aged individuals (40-69 years of age) using a large sample (n = 4558) from a community-living population, who resided in Rokunohe town, Aomori prefecture in northern Japan (response rate = 69.8%), was undertaken. This town recently had a lot of suicides. Two-way anova was used to analyze the effects of stressor and social support on the Center for Epidemiologic Studies Depression scale scores. The authors found a stress buffering effect of social support on the depressive symptoms occurring in middle age, however, a significant difference in the stress buffer effect was only observed in male subjects. Moreover, when the authors take reciprocity into account, the effect of the buffer on depression was found not only in males receiving support but in males providing support as well. In conclusion, pertaining to males, social support reduces depressive symptoms under stressful circumstances in middle age, not only when they receive such support but also when they provide it. Therefore, these findings suggest that reciprocal social support is important for males in relation to community mental health.

Características do apoio social oferecido a idosos de área rural assistida pelo PSF

Trata-se de um trabalho epidemiológico do tipo transversal, com o objetivo de descrever as características do apoio social e identificar associações entre as variáveis sociodemográficas e categorias de suporte social, em população rural do Bairro dos Aleixos, no município de Taquarituba SP. Para medir o apoio social, utilizou-se da escala Medical Outcomes Study (MOS), traduzida para o português e validada em nosso meio. A população caracterizou-se por mulheres, predominantemente da raça branca, entre 60 a 69 anos, casadas e/ou vivendo em concubinatos, de baixa renda e residindo em domicílios multigeracionais. Escores de apoio médios elevados foram identificados, indicando situação favorável entre os idosos estudados. Em termos médios, a categoria de apoio com pior escore foi "interação social positiva". A análise bivariada demonstrou uma diferença significativa entre escore de apoio afetivo e de apoio emocional com número de pessoas no domicílio e maior freqüência de escores altos de interação social (3º tercil) em idosos do sexo masculino e naqueles com maior grau de escolaridade. O estudo apontou ainda que escores de apoio social menores foram mais freqüentes em mulheres, analfabetos, viúvos ou solteiros, idosos com renda entre um e dois salários mínimos.

Activity as a predictor of mental well-being among older adults

This eight-year follow-up study examines the roles of physical and leisure activity as predictors of mental well-being among older adults born in 1904-1923. As part of the Evergreen project, 1224 (80%) persons aged 65-84 years were interviewed at baseline (1988), and 663 (90%) persons in the follow-up (1996). Mental well-being factors including depressive symptoms, anxiety, loneliness, self-rated mental vigour and meaning in life were constructed using factor analysis. The predictors of mental well-being included physical and leisure activity, mobility status and number of chronic illnesses. We used a path analysis model to examine the predictors of mental well-being. At baseline, low number of chronic illnesses, better mobility status and leisure activity were associated with mental well-being. Baseline mental well-being, better mobility status and younger age predicted mental well-being in the follow-up. Explanatory power of the path analysis model for the mental well-being factor at baseline was 19% and 35% in the follow-up. These findings suggest that mental well-being in later life is associated with activity, better health and mobility status, which should become targets for preventive measures.

INTERPERSONAL RELATEDNESS AND SELF-DEFINITION IN LATE ADULTHOOD DEPRESSION: PERSONALITY PREDISPOSITIONS, AND PROTECTIVE FACTORS

This study addresses depression in late adulthood within the context of Blatt's (1974; 1991) theory of development and vulnerabilities to depression. Participants were a sample of 237 Israeli community-dwelling old adults (age 65–75) in good health and functioning well. The authors assumed that in this developmental period, normally beset with questions about self-identity and interpersonal relatedness, the associations among Self-criticism, the Neediness component of dependency, and depressive symptomatology are moderated by participants' perceived social support as well as by their fear of death. As expected, the correlational results confirmed that depression in late adulthood is associated with Self-criticism, Neediness, fear of death, and low perceived social support. Additional results illustrated the protective role of Efficacy and Connectedness, as well as the buffering roles of social support and low fear of death in the relation between vulnerabilities to depression and depressive symptoms in late adulthood. The overall findings highlight the relevance of personality vulnerability factors in depression in late adulthood and the need to consider a range of moderating factors that may serve to protectively buffer or exacerbate the impact of personality vulnerability factors.

Stability and Change in the Perceived Social Support of Older Taiwanese Adults

OBJECTIVE

The purpose of this study is to examine stability and change in Taiwanese elders' perceptions about the availability of social support and the sociodemographic and cultural factors associated with change.

METHODS

This study uses data from four waves of the Survey of Living Status of the Elderly in Taiwan that spans a 10-year period and employs latent growth curve models to examine trajectories of perceived support and the sociocultural factors that may explain variability in baseline levels of support and variability in changes in support as respondents age.

RESULT

Perceptions about social support appear to follow a linear trajectory across age, with significant variation in baseline perceptions and in patterns of change in perceived support across the sample. Sociocultural factors primarily explain differences in initial levels of support but also have some effect on changes in support.

DISCUSSION

Despite the increasing pressures and demands on adult children's time that are associated with social and economic development, the elderly in Taiwan on average feel supported by their social networks, with the perceived availability of support increasing with age.

The effect of spousal mental and physical health on husbands' and wives' depressive symptoms, among older adults: longitudinal evidence from the Health and Retirement Survey

OBJECTIVE

To estimate the effect of spousal depressive symptoms and physical health on respondents' depressive symptoms in a national sample of older married couples.

METHOD

We used data on 5,035 respondent husbands and wives from the 1992 and 1994 waves of the Health and Retirement Survey. Multivariate regression models were estimated to examine the impact of spousal depressive symptoms and physical health on respondents' depressive symptoms.

RESULTS

Adjusting for respondent mental and physical health and sociodemographic traits, having a spouse with more depressive symptoms was associated with significantly higher follow-up depressive symptoms in the respondent (p < .001). Controlling for spousal depressive symptoms, a decline in the spouses' physical health was associated with a significant reduction in respondent depressive symptoms (p < .05).

DISCUSSION

Our findings suggest that health care providers treating older adults should be sensitive to the possibility that spouses may be affected when clients suffer poor mental or physical health.

Social ties and perceived support: two dimensions of social relationships and health among the elderly in Taiwan

OBJECTIVES

Assess the effects of social relationships on physical and mental health among the elderly in Taiwan.

METHODS

Using 4 waves of a survey of the elderly, we examine the relationship between social ties and perceived support and four health outcomes--mortality, functional status, self-assessed health, and depression.

RESULTS

Perceived support and social ties are related to health, but many of the apparent effects are attenuated in the presence of controls for prior health. However, positive perceptions about support are protective of mental (but not physical) health.

DISCUSSION

If baseline health is ignored, estimates of the effects of social relationships on health at a given stage of life are likely to be inflated by reverse causality or by effects occurring prior to baseline. Inclusion of controls for initial health reveals that, in general, the relationship between social support and health at the older ages in Taiwan is relatively modest.

Physical functioning: self-report and performance measures are related but distinct

STUDY DESIGN

Cross-sectional study of 63 patients with chronic low back pain (CLBP).

OBJECTIVES

To determine the relationship between the SF-36 physical functioning (PF) scale and physical performance on a modified symptom limited treadmill test, and to determine the effect of disability status and SF-36 mental health (MH) scores on self-reported physical functioning and on physical performance.

SUMMARY OF BACKGROUND DATA

Patients with CLBP report low levels of physical functioning. Because self-report measures are influenced by psychosocial factors, such as disability and low MH, a common recommendation is to supplement self-report with objective or physical performance testing. Little information exists regarding whether performance testing is also influenced by disability and low MH.

MATERIALS AND METHODS

Patients completed the SF-36 and performed a maximal, symptom-limited, modified treadmill test. Total walking time and heart rate on the treadmill were registered. The effects of disability and low MH on self-report and performance testing were calculated by unpaired Student's t-testing and effect size estimation.

RESULTS

A strong relationship between the PF scale of the SF-36 and treadmill walking time was found, but there was little evidence of overlap between these physical functioning domains. Both disability status and low MH had a much larger effect on self-report measures than on physical performance.

CONCLUSIONS

Self-report measurements and performance-based assessments provide information about distinct, although related, domains of physical functioning. Disability and low MH are associated with lower SF-36 PF scores. Our results confirm that self-report measures require supplementation with objective performance testing to provide optimal assessment for patients with CLBP.

The role of mastery and social resources in the associations between disability and depression in later life

PURPOSE

Although disability is widely acknowledged as a risk factor for late-life depression, few studies have studied the potential of psychosocial factors to alter the association between disability and depression. The present study assessed the impacts of mastery and social resources (social network, social support, and satisfaction with support) on depression and, in particular, whether they modify the link between disability and depression.

DESIGN AND METHODS

The direct and moderating effects of mastery and social resources were empirically tested using a sample of 406 community-dwelling older adults who were cognitively intact (mean age = 72.3).

RESULTS

Higher level of mastery and greater satisfaction with support had significant direct effects on depression and also buffered the adverse impact of disability on depression.

IMPLICATIONS

The findings support the importance of psychosocial factors in modifying the association between disability and depression and suggest that efforts to enhance positive psychosocial attributes should be emphasized in interventions for older adults.

Depression, visual acuity, comorbidity, and disability associated with age-related macular degeneration

OBJECTIVE

To examine (1) the prevalence of depressive disorders in community-dwelling adults with advanced age-related macular degeneration (AMD) and (2) the relationship in this population between depression, visual acuity, the number of comorbid medical conditions, disability caused by vision loss as measured by the National Eye Institute-Vision Function Questionnaire (NEI-VFQ) and the vision-specific Sickness Impact Profile (SIPV), and disability caused by overall health status as measured by the Sickness Impact Profile-68 (SIP).

DESIGN

Analysis of cross-sectional baseline data from a randomized clinical trial.

PARTICIPANTS

Participants were 151 adults aged 60 and older (mean age, 80 years) with advanced macular degeneration whose vision was 20/60 or worse in their better eye.

METHODS

Subjects were interviewed using measures of depression, disability, and chronic medical conditions. Visual acuity was obtained. Nonparametric correlation analyses and linear regression analyses were performed.

MAIN OUTCOME MEASURES

Structured Clinical Interview for DSM-IV (SCID-IV), Geriatric Depression Scale (GDS), NEI-VFQ, SIPV, and SIP.

RESULTS

Of the participants, 32.5% (n = 49) met SCID-IV criteria for depressive disorder, twice the rate observed in previous studies of community-dwelling elderly. Over and above depression (GDS), visual acuity aided in prediction of the level of vision-specific disability (NEI-VFQ and SIPV).

CONCLUSIONS

Depressive disorder is a significant problem for the elderly afflicted with advanced macular degeneration. Further research on psychopharmacologic and psychotherapeutic interventions for depressed AMD patients is warranted to improve depression and enhance functioning. Over and above depression, visual acuity aided in predicting vision-specific disability. Treatment strategies that teach patients to cope with vision loss should be developed and evaluated.

Social support increases in the year after inpatient treatment of depression

High levels of social support are reported to protect against major depressive episode (MDE), but little is known about how social support changes during MDE. In this study, we measured total social support and four subtypes of social support in 75 psychiatric inpatients at the time of admission and one year later. The four subtypes of social support were tangible support, affectionate support, positive social interaction, and emotional/informational support. The majority of the sample were women (81%) with a mean age of 53.7+/-14.9 years. The severity of depressive symptoms improved over the year and was accompanied by a significant increase in two types of social support -- positive social interaction, and emotional/informational support. There was no significant change in tangible support or affectionate support. Linear regression showed that changes in all four subtypes were correlated with changes in depressive severity after adjustment for age, gender, and baseline clinical characteristics. While Instrumental Activities of Daily Living (IADL) scores also improved throughout the period of observation, and while the change in IADL scores were significantly associated with changes in social support, change in IADL scores were no longer significantly associated with change in social support after adjustment for change in depression severity. These results suggest that supportive relationships improve after psychiatric hospitalization for MDE, and these changes are best explained by reduction in depression severity.

Effects of caregiving, gender, and race on the health, mutuality, and social supports of older couples

OBJECTIVES

The purpose of this article is to report caregiving, gender, and race effects on the physical health, social supports, and mutuality of older couples.

METHODS

The study involves cross-sectional results from a longitudinal study of 234 older couples, 118 in caregiving situations and 116 comparison couples. Spouses were interviewed in their homes.

RESULTS

Spousal older caregivers are in poorer physical health than noncaregivers but have no greater numbers of social supports to help them in the caregiving role. Also, African Americans are in poorer physical health than Caucasians; yet, as caregivers, they have no greater numbers of social supports than Caucasian caregivers. Although females have more social supports than males, female caregivers have more negative feelings about their husbands than male caregivers have about their wives.

DISCUSSION

Males and African Americans are in potentially more severe caregiving situations than their female and Caucasian counterparts. Results of this study are compared to Wallsten (1999), which found that African Americans and males had more favorable psychological indicators of stress. The two studies complement each other but open the question of response bias as a factor.
