A Study on the Development and Validation of an Intergenerational Solidarity Measuring Tool Using Mixed Methods

Intergenerational conflicts caused by rapid socioeconomic changes have highlighted the importance of strengthening intergenerational solidarity, emphasizing the necessity of tool designed to measure intergenerational solidarity. This study developed a standardized intergenerational solidarity measurement tool using mixed methods. In the qualitative research stage, 27 main survey questions were derived through literature research, in-depth interviews, and content validity verification. In the quantitative research stage, based on the results of a survey of 1,109 adults, both exploratory and confirmatory factor analyses of the questions were conducted, and the validity of the questions was confirmed. The analysis results were used to develop a 10-item measurement tool consisting of two factors: “recognition of intergenerational solidarity in the family” and “recognition of social intergenerational solidarity.” This study is the first attempt to develop a standardized measure of intergenerational solidarity, and it can be used for nationwide panel surveys in academic and policy research.
