Abstract
This study aims to identify the psychometric properties and factorial structure of the WHO Disability Assessment Schedule (WHODAS 2.0) within the Arabic context. A quantitative, cross-sectional, and descriptive research design was adopted to achieve the study's objectives. The researcher employed a convenient random sampling technique, involving 456 adult participants representing various genders and residential locations.
Exploratory Factor Analysis (EFA) of the WHODAS 2.0 revealed four distinct factors that reflect different dimensions of functioning and disability. Factor 1 includes items related to mobility, cognitive functioning, and social or domestic activities, with moderate to high loadings indicating strong associations with these domains. Factor 2 comprises items addressing social interaction, adaptation, and cognitive functioning, displaying moderate loadings that suggest specific interrelations. Factor 3 is characterized by a single item with a very high loading, indicating a strong relationship that warrants further investigation. Factor 4 consists of items with moderate loadings, potentially linked to cognitive or mobility-related aspects of functioning.
These identified factors offer a structured framework for interpreting the underlying dimensions assessed by WHODAS 2.0, thereby supporting its use in clinical and research settings focused on understanding and addressing various aspects of functioning and disability
