Objectives Due to the significant psychological and emotional burdens of mothers of children with autism spectrum disorder (ASD), enhancing internal sources of happiness in them may play a crucial role in improving their mental health. The present study aimed to investigate the short-term effect of a happiness training program based on Lyubomirsky’s positive activity model on inner and psychological well-being of mothers of children with ASD in Iran. 
Methods This is a randomized controlled clinical trial with a pre-test/post-test design. Participants were 30 mothers of children with ASD in Qom, Iran. They were randomly assigned to intervention and control groups. The intervention group received the happiness training program in eight 90-minute sessions. The instruments included the Subjective Happiness Scale (SHS) and Ryff’s Scales of Psychological Well-Being (SPWB). Data were analyzed using ANCOVA.
Results After the intervention, the intervention group showed significantly higher scores in inner well-being and in the psychological well-being domains of autonomy and environmental mastery compared to the control group (P<0.05).
Conclusion The happiness training program based on Lyubomirsky’s positive activity model can effectively improve both inner and psychological well-being in mothers of children with ASD, which may contribute to enhancing their overall quality of life.
