다국어 초록 (Multilingual Abstract)

Purpose: This study aimed to verify the longitudinal relationship between self-esteem and depression in the elderly using a cross-lagged regression model. Methods: A secondary data analysis was conducted using data from the Korean Welfare Panel Study(KOWEPS). Data on the self-esteem and depression of 1,084 elderly individuals who were 65 years old in 2006 and who had responded to all four waves of the survey over a five-year period were analyzed. Results: Both self-esteem and depression in the elderly showed statistically significant positive autoregressive effects, and the au- toregressive coefficients for both self-esteem and depression levels increased over time. Self-esteem and depression also showed significant cross-lagged effects. That is, self-esteem at a previous time point significantly affected depression at a later time point, and vice versa. However, between the ages of 70 and 75 years, there were no significant cross-lagged effects for either self-esteem or depression. Conclusion: This study confirmed that self-esteem and depression in the elderly have a mutually causal relationship. Additionally, since there were significant differences observed according to the age groups in the elderly, customized interventions reflecting the characteristics of each age group are necessary for the effective improvement of self-esteem and depression in the elderly.
