Content Validation and Pilot Testing of the Promoting Active Lifestyle Among Children With Disability Questionnaire...

Primary carers, school teachers, and administrators are key influencers in promoting active lifestyle among children with disabilities (CWD). Guided by the Capability, Opportunity, Motivation, Behavior Model, the Promoting Active Lifestyle among CWD (PALS) Questionnaire aims to determine these influencers' perceptions, capabilities, opportunities, and motivations in active healthy lifestyle promotion. This study evaluated the content validity and feasibility of the PALS Questionnaire in Filipino and English.

Six experts rated the relevance of the items in the Filipino and English versions of the PALS Questionnaire. Item and scale content validity indices and agreement among raters (modified kappa k*) were computed. The questionnaires were revised and pilot tested among 11 participants comprising primary carers, and special education teachers and administrators using 3 methods of administration: online survey, phone interview, and pen-and-paper survey.

Scale-level content validity index indicated excellent content validity (0.96-0.97). Item-level content validity index ranged between 0.67 and 1.00. Interrater agreement on the relevance of all items was excellent (k* = .82-1.00), except for the item on teaching assistants (k* = .56). Most participants found the items easy to understand. The average time needed to complete a questionnaire was 30 minutes. The online version of the questionnaire was identified as the most feasible mode of administration.

The PALS Questionnaire is a useful instrument for understanding Filipino primary carers' and educators' perceptions on promoting CWD's active healthy lifestyle. Information from the PALS Questionnaire could inform initiatives toward better CWD health and quality of life.
