Digital Self-Compassion Writing Intervention to Support Mental Health of Parents of Autistic Individuals

This randomized controlled trial aims to evaluate the feasibility, acceptability, and preliminary efficacy of a digital self-compassion writing intervention for parents of autistic individuals. Participants will engage in a 14-day self-compassion writing program delivered via a WeChat mini-program. The study seeks to answer the following questions: * Is the study design and digital self-compassion writing intervention feasible and acceptable for parents of autistic individuals? * Does the intervention lead to greater improvements in self-compassion and mental health outcomes compared to the control group? * Do baseline characteristics moderate the intervention effect compared to the control group? * Among intervention participants, do satisfaction and usage patterns predict greater improvements in outcomes? * Does improvement in self-compassion mediate changes in mental health outcomes?
