Treatment choices in autism spectrum disorder: The role of parental illness perceptions

Abstract

A cross-sectional design was employed. Parents of a child with Autism Spectrum Disorder (ASD) were asked to complete a modified version of the Revised Illness-Perception Questionnaire (IPQ-RA) and answer questions about information-seeking activities and treatments used. Internal consistency, construct validity, and factor structure were assessed. Multivariate logistic regressions were performed. Eighty-nine parents having a child with ASD took part in the study. Five subscales of the IPQ-R were replicated. Causes were split into personal, external and hereditary factors. The most highly rated main cause was a genetic cause. Perception of seriousness of the disease was associated with the use of educative methods and unpredictable course of disorder associated with drug use. A higher sense of personal control was associated with reduced use of nutritional or pharmaceutical treatments. Attendance to training programs was associated with higher hereditary beliefs and lower perception of cyclical timeline. The IPQ-RA captures components of representations of autism and provides a reliable mean for exploring illness concept in parents of a child with ASD. Some illness dimensions may prevent parents from having the opportunity to modify their concept of autism. Such measure may be useful for assessing the modification of potentially malleable beliefs with psychoeducational interventions.
