Development and Content Validity of the Participation and Sensory Environment Questionnaire.

Qualitative methodology was used to develop items for a questionnaire designed to examine the perspectives of parents regarding the impact of the sensory environment on participation for children aged 3 to 5 who have autism spectrum disorders (ASD). A total of 34 parents/caregivers of children with ASD and 8 experts in ASD and/or measurement completed qualitative interviews for concept, content review, and cognitive interviewing. The result was a pool of 35 items for home/community domains for 3 scales. The outcome of this study was the development and content validation of the Participation and Sensory Environment Questionnaire (PSEQ).
