Primary use / Purpose: 

The APSI is a unique measure of parenting stress specific to core and co-morbid symptoms of autism.


Stress among parents of children with autism has been found to be particularly high. Core symptoms, as well as co-morbid behavioural and physical problems, have been found to affect parents’ stress levels. The APSI was designed for clinical use to identify areas where parents need support with parenting skills, and to assess the effect of intervention on parenting stress.

The APSI was developed following many interviews of parents of children with autism. The Items fall into three categories: the core social disability, difficult-to-manage behaviour, and physical issues. Items are rated as being ‘Not stressful’, ‘Sometimes creates stress’, ‘Often creates stress’, ‘Very stressful on a daily basis’, to ‘So stressful that sometimes we feel we cannot cope.’ The APSI indicates how much stress parents are experiencing and what factors are causing this stress.


The overall APSI scale score demonstrates acceptable internal consistency and test–retest stability for parents of children with autism and other developmental disabilities (Silva & Schalock, 2012).
