Systematic Review of the Efficacy of Parent-Mediated Interventions in Reducing Problem Behaviours Shown by Autistic...

Problem behaviours exacerbate the challenges associated with the core characteristics of autism during adolescence. Parenting interventions have demonstrated efficacy in addressing such behavioural challenges in younger autistic individuals, however, their evidence for autistic adolescents is sparse, particularly in low-income settings.

This systematic review narratively synthesised studies outlining parenting interventions targeting problem behaviours in autistic adolescents.

Seven studies were included with three providing comparable quantitatively data for their efficacy in improving problem behaviours. Five out of seven studies reported positive evidence on reducing problem behaviours. Characteristics including fewer sessions, instructional mode of intervention delivery and use of behavioural management skills were most commonly shared among statistically significant studies. Parenting interventions had a positive effect on adaptive behaviours for children, and improved parent wellbeing and knowledge. The overall satisfaction with interventions was high, however, only one study was conducted in a lower- and middle-income country.

The findings underscore the encouraging evidence in an understudied area. The results emphasise the need to conduct further research for autistic adolescents and highlight potential parent-mediated interventions carry, given their acceptability and logistically scalable nature.
