Exploratory Research on Happiness Trajectory and Related Factors: Exploring Disability and Veenhoven’s Discussion

Abstract

This study started with the question of ‘Is happiness really declining in Koreans?’ To this end, the trajectory of adult happiness was estimated using data from the Korean Welfare Panel and the influencing factors were examined. In addition, given that Korea is a country that ratified the UN Convention on the Rights of Persons with Disabilities, the trajectory and factors influencing happiness were explored according to disabilities. The subjects of the analysis were 11,844 adults aged 19 or older who participated in the Korean Welfare Panel Survey. The happiness trajectory, a dependent variable, was built using the subjective happiness index measured every year for four years from 2017 to 2020. The predictors of the happiness trajectory used variables as of 2017, the starting point. This study controlled for socio-demographic variables (age, gender, education, income, and with or without spouse), and used, following Veenhoven’s discussion, individual system variables (subjective health status and self-esteem) and social system variables (social relationship satisfaction and the National Basic Livelihood Security Program) as exogenous variables. On average the happiness trajectory showed an increase with time. Also, all the predicted factors, with the exception of the National Basic Livelihood Security Program, had a significant positive effect on the happiness trajectory. There were significant differences in the happiness trajectory between people with a disability and those without. But there was no difference between the two groups in the predictive factors. Based on these research results, implications and follow-up studies were discussed to promote happiness of the entire population and the disabled population.
