Initial Development and Content Validity of the Experiencing Day-to-Day Life Questionnaire (EDLQ): A Measure of Objective Participation and Subjective Experience in Occupation

This study describes the development of the Experiencing Day-to-Day Life Questionnaire (EDLQ) and the initial evaluation of its content validity. The EDLQ was designed to capture both objective participation and subjective experience across seven experiential occupational categories. Using a quantitative descriptive design, content validity was assessed through the input of two participant groups: content experts (N = 11 occupational therapists) and mothers of children with ADHD with lived expertise (N = 10). Content experts rated item relevance and representativeness, while mothers evaluated clarity and comprehensibility through written feedback. Findings demonstrated strong indices of content validity, with revisions suggested to improve clarity, phrasing, and accessibility. These results provide initial support for the EDLQ as a client-centered measure of occupational experience, offering potential to enhance understanding of how objective participation and subjective experience may jointly shape health and well-being.
