When the "Golden Years" Turn Blue: Using the Healthy Aging Literature to Elucidate Anxious and Depressive Disorders in Older Adulthood

Examining Differences in Behavioural Avoidance Between Younger and Older Adults

OBJECTIVES

Studies have found older adults report fewer anxiety symptoms than younger adults. As behavioral avoidance is theoretically associated with maintaining anxiety, this study sought to examine age-related differences in avoidance and anxiety in a cross-cultural sample of older (n = 60, 60-92 years) and younger adults (n = 70; 17-24 years).

METHODS

Community dwelling participants from Australia and the United States of America completed self-report measures of anxiety, worry, and depression. Participants also self-rated levels of avoidance to 133 common fearful situations using a card sort task.

RESULTS

Older adults reported significantly less avoidance of age-adjusted social and medical scenarios, more avoidance of aggressive scenarios, with no significant difference for animal or agoraphobic scenarios when compared to younger adults. Age-related effects were no longer significant in full models, in which the main effect of anxiety explained variance in avoidance for social, medical, animal, agoraphobic, but not aggression scenarios.

CONCLUSIONS

Age differences in avoidance behavior were accounted for by differences in anxiety symptoms, except for avoidance of aggressive scenarios, which was not associated with anxiety. CLINICAL IMPLICATIONS: Age differences in levels of avoidance of common fearful situations were found, and may be associated with differences in anxiety symptom severity.

Assessing urban-rural differences in the relationship between social capital and depression among Ghanaian and South African older adults

Introduction

Research has demonstrated benefits of social capital on depression, but variations in this relationship by geographic characteristics such as urbanicity have rarely been investigated.

Methods

Using survey data on 4,209 Ghanaian and 3,148 South African adults aged 50 and above from the World Health Organization (WHO) Study on Global AGEing and Adult Health (SAGE), exploratory and confirmatory factor analyses were conducted to extract dimensions of social capital from survey items. Structural equation models with the extracted factors were then used to estimate the associations between social capital and depression in each sample and assess differences between urban and rural settings with measurement and structural invariance tests.

Results

Factor analyses suggested three dimensions of social capital representing community engagement, sociability, and trust. Urbanicity did not substantially modify the effects of social capital on depression in either setting, but urban-rural differences in the measurement and level of social capital were observed. Urban Ghanaian older adults were less socially integrated and trusting than older rural residents (standardized mean difference: -0.28, -0.24, and -0.38 for community engagement, sociability, and trust, respectively) while urban South African older adults appeared less engaged in community activities but significantly more trusting and socially active informally than older rural residents (standardized mean difference: -0.33, 0.30, and 0.17 for community engagement, sociability, and trust, respectively). Moreover, while trust was associated with a lower risk of depression in South Africa overall, sociability and trust were associated with an increased risk of depression in Ghana.

Conclusions

Results indicate that the composition and average levels of social capital differ between urban and rural older adult residents in Ghana and South Africa although urban-rural differences in the strength of the association between social capital and depression were not substantial. Furthermore, the associations between social capital and depression are context-specific and are not uniformly beneficial.
