IntroductionSchool-age autistic children commonly experience social communication and interaction challenges in their everyday lives. While international evidence suggests that social skills group training (SSGT) programmes can support autistic children, improving their psychosocial functioning, to date there is no standardised evidence-based SSGT tailored towards the needs of autistic children aged 8–12 years living in the Chinese Mainland. Therefore, the primary objective of this study will be to evaluate the feasibility and acceptability of a culturally adapted 16-session version of the social skills programme KONTAKT in Chinese autistic children. Additionally, preliminary efficacy and cost-effectiveness will be assessed to inform a future definitive trial.Methods and analysisThis study will employ a randomised, single-blinded, waitlist-controlled feasibility design with 36 Chinese autistic children aged 8–12 years with IQ over 70 referred to the Child Development and Behavior Center in Guangzhou, China. Participants will be randomly assigned to either the immediate training group or the delayed training group stratified by sex. Feasibility will be assessed using quantitative and qualitative data obtained from the KONTAKT CHILD participants, their parents and facilitators of the programme. Preliminary efficacy and cost-effectiveness are assessed via quantitative data obtained at five time points. The primary efficacy outcome is participants’ improvement in social skills as measured by the Contextual Assessment of Social Skills. Other outcomes include parents and teachers’ reports of participants’ autistic traits and adaptive functioning, participants’ self-report and projective tests for self-assertiveness and psychosocial functioning, and parent reports on parental reflective functioning and perceived school support. Common process factors and their effects on outcomes will also be explored. Cost-effectiveness will consider from both societal and healthcare perspectives.Ethics and disseminationThe current study protocol has been reviewed and ethics approval has been obtained from the Ethical Board Committee at the Third Affiliated Hospital of Sun Yat-sen University (II2023-119-01). The trial was pre-registered in Chinese Clinical Trials (ChiCTR2300072136) on 5 June 2023. The results of this trial will be actively disseminated through peer-reviewed publications and conference presentations. Any identifiable personal information will be anonymised to protect confidentiality.Protocol version2.0, 31 July 2024.Trial registration numberChiCTR2300072136.

In the current study, functional near-infrared spectroscopy (fNIRS) was used to collect resting-state signals from 77 males with autism spectrum disorders (ASD, age: 6~16.25) and 40 typically developing (TD) males (age: 6~16.58) in the theory-of-mind (ToM) network. The graph theory analysis was used to obtain the brain network properties in ToM network, and the multiple regression analysis demonstrated that males with ASD showed a comparable global network topology, and a similar age-related decrease in the medial prefrontal cortex area (mPFC) compared to TD individuals. Nevertheless, participants with ASD showed U-shaped trajectories of nodal metrics of right temporo-parietal junction (TPJ), and an age-related decrease in the left middle frontal gyrus (MFG), while trajectories of TD participants were opposite. The nodal metrics of the right TPJ was negatively associated with the social deficits of ASD, while the nodal metrics of the left MFG was negatively associated with the communication deficits of ASD. Current findings suggested a distinct developmental trajectory of the ToM network in males with ASD from childhood to adolescence.

Purpose: The Program for the Education and Enrichment of Relational Skills (PEERS.sup.®) is a group-based social skills training program for adolescents on the autism spectrum. Although the program has been shown to be effective in improving social skills in autistic adolescents, evidence of its effectiveness from the Mandarin-speaking Chinese population is sparse. The present study used a non-randomized, pre- and post-intervention research design to investigate the feasibility and cultural validity of the program, as well as examine the moderators of intervention outcomes. Methods: Thirty-three autistic adolescents with intelligence quotient above 70 (M.sub.age = 13.57, SD.sub.age = 1.43; Male: Female 25:8) and their parents received 14 concurrent 90-minute sessions. Adolescents' autistic traits, challenging behaviors, emotional functioning, socio-cognitive process, social environment factors (school support), and caregivers' well-being were evaluated. Results: The findings suggest that with minor adjustments, the Mandarin version of PEERS.sup.® was generally acceptable and feasible for autistic adolescents and their parents. PEERS.sup.® may improve the social skills knowledge, reciprocal communication abilities, and emotional well-being of autistic adolescents. Also, participants with a higher level of school support, and parents with lower perceived subjective well-being at baseline may gain more benefits from PEERS.sup.®. The cultural adaptation and acceptability of the Mandarin Version of PEERS.sup.® were discussed. Conclusion: This feasibility study (Chinese Clinical Trial Registry: ChiCTR2200061417, 2022-06-23, retrospectively registered) provides a basis for further randomized control trials of the Mandarin version of PEERS.sup.®.
