The Mechanism of Ageism: The Relationship Between Perceived Ageism and Depressive Symptoms in Later Life

Extending the human life span has long been a desire of human beings. It seems the wish has been actualized. However, simply living a long life does not always seem to be a blessing. Older adults report a lower level of psychological well-being and quality of life and even have a higher rate of suicide, compared to the general population. Furthermore, as older adults are likely to experience the death of a loved one, deteriorating health, retirement, and changing relationships with others, older adults have a high risk of depression. Social work has a long history of providing social services to older adults. In particular, social work has provided older adults with a variety of services to enhance their quality of life and mental health status. Because ageism is one form of discrimination that social work has long been concerned with, this study focuses on the relationship between perceived ageism and depressive symptoms among older adults. Therefore, the purpose of this study is to examine the relationship between perceived ageism and depressive symptoms among older adults and to investigate the mechanism linking perceived ageism to late-life depression. Three primary effects were examined: the direct effect of perceived ageism on depressive symptoms in later life, the mediating effects of self-perception of aging and purpose in life on the relationship between perceived ageism and late-life depression, and the moderating effect of perceived ageism on the association between religiosity and depression among older adults. The stress process model was used to provide an overall idea to explain the three types of the effects related to the mechanism of ageism. Cooley's looking-glass self, Beck's cognitive theory of depression, and Levy's stress embodiment theory were used to explain the mediating effect of self-perception of aging, and Beck's cognitive theory of depression was applied again to clarify the mediating effect of purpose in life. The stress buffer theory and the life-span theory of control indicated the moderating effect of perceived ageism on the relationship between religiosity and depression. Secondary analysis of existing data was conducted using the Health and Retirement Study (HRS) datasets, a longitudinal panel study of the U.S. population ages 50 and over. The sample of this study was 3,991 participants, who were older adults ages 65 and over and whose answers were available for the study analyses. Descriptive and preliminary analyses were performed to roughly examine the relationships between variables. With regard to the direct effect of perceived ageism on depressive symptoms, multiple regression analyses were performed controlling for significant variables. With regard to the mediating effects of self-perception of aging and purpose in life, structural equation modeling (SEM) analyses using structural regression models were conducted. In respect to the moderating effect of perceived ageism on the relationship between religiosity and depression, SEM analyses with multiple groups were performed. Based on the results of the several different analyses, a direct relationship between perceived ageism and late-life depression was found. That is, older adults who perceive ageism are likely to have a higher level of depressive symptoms than their counterparts. This direct relationship between perceived ageism and late depressive symptoms among older adults, however, was not detected after controlling for self-perception of aging and purpose in life, indicating the full mediation effects of self-perception of aging and purpose in life. That is, older adults who perceive ageism are likely to have negative self-perception of aging, and this negative view of their own aging is likely to increase depressive symptoms. Additionally, older adults who have a negative view of their aging are likely to have a negative view of their future, and this lower purpose in life also increases depressive symptoms. The strength of the effect of religiosity on depression did not differ between the perceived age sm and the not perceived ageism groups, indicating no moderating effect of perceived ageism on the relationship between religiosity and depression. This study contributes to the existing body of knowledge by providing the information about the relationship between perceived ageism and depression and the mechanism of this relationship. Also, this study re-examined and supported established theories in the context of perceived ageism. Additionally, the current study suggests the necessity of anti-ageism policies and social work services and describes possible ways of providing such social policies and social work services at the micro, mezzo, and macro levels. The results of this study imply that more efforts and resources are necessary to reduce ageism and its negative effect on depression among older adults, and these efforts will eventually contribute to making a more just, better society.
