Although numerous studies have demonstrated that social support affects a range of life experiences, few have examined its moderating and mediating effects. In the current study, 479 Chinese parents of children with ASD (aged 3–18 years) completed the surveys assessing parenting stress, social support and life satisfaction. Results indicated that parenting stress, social support and life satisfaction were significantly related. Moreover, social support both mediated and moderated the influence of parenting stress on life satisfaction. These findings imply that parenting stress and social support are critical indicators of life satisfaction and can serve as basic intervention strategies that promote life satisfaction among Chinese parents of children with ASD.
