This study was conducted in order to examine the influence of sociodemographic characteristics, family resilience, self-help groups characteristics of families with the disabled on the establishment of permanency planning targeting the parents of adult children with developmental disabilities. The structured survey was conducted targeting 264 parents of children with developmental disabilities over the age of 18 years old in Gwangju and Jeollanam-do. Using SPSS 18.0 the data frequency, percentage, t-test, ANOVA and hierarchical regression analysis were conducted. The major findings were as follows:First, the need of permanency planning for adult children with developmental disabilities which their parents recognize was shown high. However, the readiness of the permanency planning for the disabled children was shown generally low. Second, the functional level of daily life, family resilience, the level of care giving burden, family income and supports from self-help groups were identified as statistically significant predictors for the level of permanency planning. The implications of those results were discussed.
