The current study examined onset and maintenance insomnia as mediators of the bidirectional relation between anxiety and depressive symptoms over a three-year period. The sample included 3,415 US community-dwelling Medicare beneficiaries aged 66-103. Participants completed measures of types of insomnia, anxiety symptoms, and depressive symptoms at four time points. Analyses included two double mediation models adjusted for baseline depressive or anxiety symptoms, chronic health problem burden, use of sleep medications, age, and sex. Both covariate-adjusted models showed significant direct relations between anxiety and depressive symptoms, and these relations were modestly partially mediated by onset and maintenance insomnia. In older adults, onset and maintenance insomnia are distinct outcomes of both anxiety and depressive symptoms and also predictors of each symptom cluster. Further research testing these models is warranted and, if supported, may support prevention and treatment studies focused on primary and secondary prevention of these problems in older adults.

Little is known about widowhood's effects on externalizing expressions of distress, like substance use, among sexual minorities. Our study is the first to address this issue using a large national sample of LGB individuals living in the United States. Using the 2010 Aging with Pride: National Health, Aging, and Sexuality/Gender Study (n = 2,258), we ran logistic regression models predicting current smoking, past 30-day binge drinking, and past year drug use. Widowhood predicted higher odds of drug use. These results were found for currently partnered individuals, suggesting that widowhood's effects are not completely offset by current partnership. In contrast, widowhood did not predict smoking or binge drinking. All results held for women and men. Results suggest that LGB widowhood's effects on substance use vary by current partner status and substance type. These findings contrast with those of studies examining widowhood's effects on internalized expressions of distress, which consistently find detrimental effects.

We examined age differences in the within-person relationships among perceived stress (PS), perceived stress reactivity (PSR), and depressive affect (DA) as well as potential mechanisms of depression with a longitudinal moderated mediation model. Participants from the Notre Dame Study of Health & Wellbeing (N = 572) completed two to four waves of yearly assessments. Sequentially built multilevel models, in which year was nested within person, illustrated that only midlife adults experience an exacerbated effect of within-person fluctuations in PSR on the relationship between within-person PS and DA levels (γ₄₁= -.004, p < .01). Findings further suggest that PSR accounts for the PS-DA relationship. Furthermore, older adults illustrate successful emotion regulation strategies at the yearly level-resisting the negative ramifications of years of greater PS and PSR, whereas midlife adults who experience years of greater PSR would particularly benefit from stress management interventions and monitoring of DA levels.

Stereotypes about aging and aging anxieties are common and when internalized are related to poor physical and psychological outcomes. As a result, older adults may view themselves as having their best years behind them. The present study investigates ageism and aging anxiety as barriers to positive self-development. Participants (n = 360) between ages of 19 and 77 years old (M = 39, SD = 15.9) were recruited using Amazon Mechanical Turk (MTurk) and completed measures of Ageism, Aging Anxiety, and were asked to identify when they have been or will be their Best Self. With increasing age, adults with more internalized ageism and more aging anxiety, specifically physical appearance and fear of loss, identified their Best Self with a time in the past. These findings support the idea that internalization of ageism and aging anxiety can be counterproductive for expectations for growth as one ages.

Age bias on personality pathology measures creates challenges regarding assessment of personality disorders among older adults. This study cross-sectionally examined age bias on measures of the Alternative Model of Personality Disorders' (AMPD) two diagnostic criteria. Younger and older adults in the United States completed the Levels of Personality Functioning Scale-Self-Report (LPFS-SR) and Personality Inventory for Diagnostic and Statistical Manual of Mental Disorders, 5th Edition-Brief Form (PID-5-BF). Differential item functioning (DIF) analyses examined bias on the item-level whereas differential test functioning (DTF) analyses investigated impacts on the domain-level. For the LPFS-SR, 23% of items demonstrated DIF, with the Empathy and Intimacy domains most impacted. For the PID-5-BF, 40% of items showed large DIF, with four of five domains demonstrating large age bias. Across measures, items showed evidence of bias for and against older adults. Findings indicate meaningful age bias on measurements of both AMPD diagnostic criteria, suggesting greater potential to mischaracterize findings when using these measures across the lifespan.

Engagement in healthier lifestyle behaviors often is motivated by a focus on the future. However, there is limited research on the associations between health behavior and future time perspective, defined as people's tendency to perceive their future as expansive or as limited. Data came from a survey of U.S. adults (N = 805, 49.3% female; M = 50 years, range: 19 to 85 years). Participants completed measures of perceptions of future opportunities and time and health behavior. Opportunities and time factors were uniquely associated with health behavior. While the perceived opportunities factor was strongly associated with better health behavior, the time factor was associated with poorer health behavior. However, this latter association was dependent on individual demographic and health status differences. These findings suggest that perceptions of future opportunities can play an important role in health behavior engagement and thus represent an important target for health promotion.

Suicidal behavior in older adults is a fundamental public health problem globally and the highest suicide rates occur in low- and middle-income countries (LMICs). However, there is limited research on suicidality among older adults, especially in sub-Saharan Africa. We sought to find out whether loneliness, stress and religiosity would be associated with suicide ideation in a sample of sub-Saharan African older adults (N = 500; aged 51-70 years, M_age= 58.97, SD = 6.16; 45.6% women). They completed the Beck Suicidal Ideation Scale, the UCLA Loneliness Scale-version 3, Perceived Stress Scale, and Religiosity Scale. Regression results showed that whereas suicidal ideation could be increased by loneliness and stress, religious older adults were less likely to report suicidal ideation. Interventions aimed at managing and protecting the mental health of older adults during their transition to late adulthood should guard them against loneliness and buffer their resilience and coping strategies with the connectedness that religiosity offers.

This study examined the relationship between household environments and trajectories of cognitive function among middle-aged and older adults in China and its urban/rural, gender, and age variations. We estimated multi-level linear growth curve models using a representative sample of 16,111 respondents aged 45 years and over from the China Health and Retirement Longitudinal Study (2011-2018). Older people who lived with a spouse, but not with children, and those with higher living expenditures, better housing quality, and indoor clean fuels for cooking had a slower cognitive decline. Living arrangement more strongly predicted men's cognitive decline, while living expenditure, solid fuel use, and housing quality significantly predicted only women's cognitive decline. Only for older adults and rural residents, those living alone had significantly faster cognitive decline than those living with a spouse only. These findings underscore the importance of improving the living conditions of older adults to help alleviate their cognitive decline.

This study examined how different sources of social support from family members (excluding partners), friends, and partners were associated with moderate and vigorous leisure-time physical activity (LTPA) among middle-aged and older adults. This study included married participants aged 45 or older (N = 2,155) from the Midlife in the United States secondary data set. Hierarchical linear regression was performed to investigate the relationship between the three sources of social support and moderate LTPA, and separately, with vigorous LTPA. Partner support (b = 0.19, p < .01), family support (b = -0.19, p < .01), and friend support (b = 0.26, p < .001) were all significantly associated with moderate LTPA. Only social support from friends was associated with vigorous LTPA (b = 0.24, p < .001). Our study emphasizes the significance of social support in influencing LTPA behaviors among middle-aged and older adults. Future programs promoting physical activity should incorporate social support from friends to have the greatest impact.

Aging anxiety is a distinct form of fear characterized by negative feelings associated with growing older. This study directly compared two common measures of aging anxiety within an older adult sample. Participants completed the Anxiety about Aging Scale, the Personal Anxiety Toward Aging Scale and several related constructs including ageism, expectations regarding aging, dementia worry, and death anxiety. The two measures significantly and strongly associated with one another. The Anxiety about Aging Scale (AAS) showed evidence of convergent validity through significant and strong correlations with ageism, expectations regarding aging, and death anxiety, and a moderate correlation with dementia worry. The Personal Anxiety Toward Aging Scale (PAAS) also showed evidence of convergent validity through strong correlations with expectations regarding aging and death anxiety, and moderate correlations with ageism and dementia worry. Factor analysis showed a better model fit for the AAS. Key findings lend support for the AAS as a psychometrically stronger measure than the PAAS for older adult assessment.
