This study examined Thai mothers’ perceptions of symptoms in young children undergoing three days of chemotherapy and explored links with maternal sensitivity and parenting stress. Fifty mother–child pairs participated, with mothers completing symptom and psychosocial measures and children wearing actiwatches. Appetite change was the most common symptom, with overall symptoms peaking on the first treatment day and then declining. Symptom severity ratings were lower than those reported in Western studies. Higher parenting stress was associated with higher perceived symptoms. Findings suggest mothers can reliably report symptoms, though cultural and contextual factors may influence symptom interpretation.
