Objectives: Depression is a major health concern for both individuals and societies. Hence, understanding the risk factors for depression is of importance. As individuals grow older, the way in which they perceive the aging process may have a significant influence on their physical and mental health. More negative perceptions of aging could put individuals at risk for social withdrawal, causing loneliness and resulting in higher levels of depressive symptoms. Methods: We use the Health and Retirement Survey, a large and longitudinal dataset spanning over a period of 8 years, to examine a model in which loneliness mediates the relationship between self-perceptions of aging and depressive symptoms. Results: Our findings suggest that loneliness indeed mediates the relationship between self-perceptions of aging and depressive symptoms. Conclusions: The results highlight to the importance of the way people view the aging process in shaping their social and mental well-being. Practitioners may want to address self-perceptions of aging when helping older adults cope with loneliness and depressive symptoms.

The study aims to examine whether the reciprocal effects of physical morbidity and depression are moderated by subjective age-that is, individuals' perception of themselves as young or old. Data from the first two waves of the Midlife in the United States study (1995-6, T1; 2004-6, T2; http://midus.wisc.edu/) were analyzed using a cross-lagged design. We assessed 3,591 individuals who participated in both waves and provided full data on all the relevant variables (mean age at T1 = 47.4). Depression and the number of chronic illnesses (the indicator of physical morbidity) were measured at both waves and were tested as predictors and outcomes in a cross-lagged model. The moderating role of subjective age was assessed by examining whether T1 variables interacted with subjective age in predicting T2 outcomes. Subjective age moderated the T1 depression-T2 morbidity relationship, so that the relationship was stronger for those with older subjective age. Subjective age did not moderate the T1 morbidity-T2 depression relationship. Older subjective age could be a risk factor for experiencing greater physical morbidity following depression.

Loneliness is considered a major issue, often negatively influencing the quality of life of individuals of all ages, and of older adults, in particular. The aims of this study are: (1) to assess the association between close social relationships and loneliness; and (2) to examine the moderating role of subjective age in this association. Married or cohabiting community-dwelling Israelis in the second half of life (N = 360) were interviewed and reported on their close social relationships, their level of loneliness, and their subjective age. The number of close social relationships was found to have a negative relationship with loneliness. Moreover, subjective age was found to moderate the relationship between close social relationships and loneliness, such that the association was weaker for those with older subjective age. Those with older subjective age are often not able to benefit from close social relationships to alleviate loneliness as much as their younger-subjective-age counterparts. Efforts to address older adults’ loneliness should consider focusing on older adults’ perceptions of aging.

Objectives: Adults’ perceptions of aging are known to affect their mental and physical health. However, not much is known about how perceptions of aging within the couple-unit affect each member of the unit. Therefore, the current study explores the effects of husbands’ and wives’ self-perceptions of aging (SPA) on each other’s physical and mental health, both directly and indirectly, through impacting each other’s SPA. Method: The study used data from the Health and Retirement Study, focusing on couples aged 50 and older. Self-rated health and Center for Epidemiological Studies Depression scale (CES-D) were used as indicators of physical and mental health. SPA was measured using the “Attitudes toward aging” subscale of the “Philadelphia Geriatric Center Morale Scale.” An actor–partner interdependence mediation model was used to examine the effects of the 2008 SPA of couples on each other’s 2012 SPA and 2016 health. Results: The SPA of both husbands and wives was associated with their own future mental and physical health in 2016, but not with that of their partner. However, their SPA was associated with their partner’s health indirectly, by influencing the SPA of the partner. That is, the SPA of both husbands and wives in 2008 impacted their partner’s SPA in 2012, which was subsequently related to that partner’s mental and physical health in 2016. Discussion: Older couples can influence each other’s health indirectly, by affecting each other’s SPA. This indicates that adults’ SPA are interconnected, and thus, the entire couple-unit should be targeted to enhance positive SPA.
