The goal of the study was to understand factors contributing to life satisfaction of parents of children with autism spectrum disorder (ASD) from the perspective of positive psychology. The challenges of parenting a child with ASD have been documented extensively, with parents experiencing higher levels of stress, depression, and lower overall mental health than parents of typically developing children. Stress can lead to mental health problems for such families. Demographic variables, FEPPTs including optimism, hope, resilience, coping flexibility and secure attachment, in addition to social support and resilience are associated with positive life adjustment and on parent’s life satisfaction. The sample size was three hundred and eighty-five parents of children with ASD in Trinidad and Tobago. There were significant differences between different levels of family structure, education level and income level in relation to the for dependent variables. Statistically significant relationships were found between the independent variables, the FEPPTs, and the dependent variables. Significant relationships were identified between PERMA and health related quality of life, subjective happiness, flourishing and life satisfaction. While the primary approach was quantitative, there was an informal and indigenous hybrid approach with qualitative engagement providing useful context which added significantly to analysis and conclusions.
