The methodology and design of the data collection had two parts. First was a quantitative validly and reliable questionnaire: Family Quality of Life Questionnaire for Young Children with Special Needs(FQoLQ-YCSN)(N=415 parents & grandparents). Second was the use of interview and narrative methods to elicit the options and experience of all participants(12 parents, 5 caregivers, 1 social worker, and 5 directors of institute of early intervention). The quantitative data obtained were statistically analysised by factor analysis, multivariate analysis of variance (MANOVA), Pearson’s correlation, canonical correlation, stepwise regression, and structural equation model; the qualitative data were analyzed by constant comparative method to identify concepts, subcategories, categories, and finally the core variable.  The major findings of this study were as follows:
1.  The most good family QoL factor was social well-being. A significant difference on total family QoL was found among the parent’s marital status, family type and income, social support network, burden of care , severity of disabilities, hour early intervention, and credit for disability. The predictors of family QoL were the family life impact, family coping effectiveness, burn of care, family income and communication.
2.      A exploratory factor analysis was used to test the factors influencing family QoL showed stronger and significant direct effects, the fitness of model was fair to good. The core variable was identified as enabling family empowerment.
     This is an exploratory study which is directed towards developing a substantive theory to explain the phenomenon of family QoL. A longitudinal study is needed to follow up the family adaptive process.
