ABSTRACT

[Purpose] This study analyzed latent groups according to changes in life satisfaction of people with intellectual disabilities and examined effects of cognitive ability, communication ability and literacy skills on classification of latent groups. [Method] Data of people with intellectual disabilities(N=363) from 2nd Panel Survey of Employment for the disabled are analyzed using latent growth class modeling. And logistic regression analysis was employed to find effect factors of life satisfaction of people with intellectual disabilities. [Results] Latent subgroups according to the life satisfaction of the people with intellectual disabilities are 4 groups : ‘high life satisfaction’, ‘average life satisfaction’, ‘Decreased life satisfaction over time’, and ‘Increased life satisfaction over time’. As a result of logistic regression analysis, cognitive ability, communication ability, and literacy skills are effect factors on classification of latent subgroups. [Conclusion] Based on this results, practical ways to improve the life satisfaction of people with intellectual disabilities were discussed.
