Introduction / Rationale:
Long-term work disability due to chronic health conditions has significant socioeconomic and personal consequences, including reduced quality of life and psychological distress. Vocational rehabilitation is essential for maintaining employability, and research indicates that the ability to perform activities of daily living (ADL) is crucial for work participation. However, standardised assessments of ADL ability in vocational rehabilitation are still limited. The ADL-Questionnaire (ADL-Q) is a validated self-reported measure of ADL performance quality, but its applicability in individuals with long-term work disability remains unexplored.
Objectives:
This study evaluates the validity and reliability of the ADL-Q in people with long-term work disability referred for a clinical assessment of functioning in Denmark.
Methods / Approach:
A cross-sectional psychometric study will apply modern test theory using Rasch Measurement Models to evaluate the validity and reliability of the ADL-Q. Participants 18–67 years old referred by municipal authorities for a clinical assessment of functioning at the Departments of Social Medicine will be included. Participants will complete the ADL-Q as part of a comprehensive clinical assessment of functioning in the Departments of Social Medicine in Denmark.
Results / Practice Implications:
Data collection is ongoing, and results will be presented at the conference. So far, 202 participants have been included in the study.
Conclusion / Significance to the Occupational Therapy Profession:
The study will provide insight into the validity and reliability of the ADL-Q for assessing ADL ability in individuals with long-term work disability. Findings may inform future efforts to standardise functional assessments in vocational rehabilitation, supporting the role of occupational therapy.
