Content Validity of a Collaborative Goal-Setting Pictorial… : JPO: Journal of Prosthetics and Orthotics
developed previously. These tools incorporated the International Classification of Functioning, Disability, and Health (ICF) and International Organization for Standardization (ISO) clinical objectives for orthoses and were structured in an approach understandable to families. This study aimed to obtain consensus on the content validity of the Table and Pictorial Tools. Methods Seventeen experts from seven countries (orthotists, physical therapists, physicians, surgeons, and engineers) were invited. A modified Delphi technique was used to evaluate and refine the Table Tool (rounds 1 and 2) and Pictorial Tool (rounds 3 and 4). Participants rated their agreement with overall tool structure, content, and feasibility of use on a 4-point Likert scale, and provided open-ended feedback. Consensus was defined as a median score ≥3 (agree) with 75% of responses ≥3. Data were collected using REDCap. After each round, thematic analysis guided document revisions and anonymized feedback.
