Although the evidence of parent training programmes for families of autistic children has continued to grow, little is known about the experiences and perceptions of key stakeholders, especially in low- and middle-income countries. This qualitative study was part of a larger real-world evaluation of a short-term intensive parent training programme in routine services delivered to caregivers of autistic children aged 3--6 years in China. It aimed to provide insights into programme acceptability, reasons for participant involvement, and factors related to programme implementation. Fourteen caregivers participated in the in-depth interviews, and two focus group discussions were conducted with eight practitioners. Data were analysed using a combination of data- and theory-driven approaches. Findings point to the needs in low autism resource settings for substantial practice and feedback; group support; individualised coaching; more autism-related knowledge, resources and activities for children and extended family members; and organisational support to practitioners. Further research is suggested to address the recommendations and assess their effectiveness empirically.
