Purpose: To evaluate the factorial and concurrent validity and internal consistency reliability of the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) 12-item version in persons with spinal cord injuries.Method: Two hundred forty-seven adults with spinal cord injuries completed an online survey consisting of the WHODAS 2.0 12-item version and measures of various psychosocial variables.Results: The initial confirmatory factor analysis (CFA) revealed that both the theoretical hierarchical model and the 1-factor model of the WHODAS 2.0 12-item version exhibited a poor fit with the data. Subsequent exploratory factor analysis (EFA) revealed a 3-factor solution consisting of the factors Activities/Participation, Self-Care, and Mobility. Each factor demonstrated adequate internal consistency. These results were confirmed by a secondary CFA. In the concurrent validity analysis, the Activities/Participation factor had the strongest relationships with the psychosocial variables under study (life satisfaction, core self-evaluations, community participation, and health-related quality of life).Conclusion: The WHODAS 2.0 12-item version is not unidimensional in persons with spinal cord injuries as predicted but instead yields a three-factor solution. However, the Activities/Participation factor appears to be the most valid measure of disability impact in persons with spinal cord injuries. Other implications of the use of the WHODAS 2.0 12-item version are discussed.

The researchers examined the factor structure and model specifications of the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) with confirmatory tetrad analysis (CTA) using partial least squares–structural equation modeling (PLS-SEM) with a sample of adult clients ( N = 298) receiving individual therapy at a university-based counseling research center. The CTA and PLS-SEM results identified the formative nature of the WHODAS 2.0 subscale scores, supporting an alternative measurement model of the WHODAS 2.0 scores as a second-order formative–formative model.

Objective: To assess the validity of the Finnish translation of the 12-item World Health Organization Disability Assessment Schedule (WHODAS 2.0). Design: Cross-sectional cohort survey study. Setting: Physical and Rehabilitation Medicine outpatient university clinic. Subjects: The 501 consecutive patients with chronic musculoskeletal pain. Main measures: Exploratory factor analysis and a graded response model using item response theory analysis were used to assess the constructs and discrimination ability of WHODAS 2.0. Results: The exploratory factor analysis revealed two retained factors with eigenvalues 5.15 and 1.04. Discrimination ability of all items was high or perfect, varying from 1.2 to 2.5. The difficulty levels of seven out of 12 items were shifted towards the elevated disability level. As a result, the entire test characteristic curve showed a shift towards higher levels of disability, placing it at the point of disability level of +1 (where 0 indicates the average level of disability within the sample). Conclusions: The present data indicate that the Finnish translation of the 12-item WHODAS 2.0 is a valid instrument for measuring restrictions of activity and participation among patients with chronic musculoskeletal pain.

Introduction There has been limited study of patient-reported outcomes (PROs) in patients at risk of limb loss. Our primary objective was to estimate the prevalence of disability in this patient population using the World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0). Materials and methods We recruited patients referred to a limb-preservation clinic. Patients self-reported their disability status using the 12-domain WHODAS 2.0. Severity of disability in each domain was scored from 1 = none to 5 = extreme and the total normalized to a 100-point scale (total score ≥25 = clinically significant disability). We also asked patients about wound-specific concerns and wound-related discomfort or distress. Results We included 162 patients. Reasons for clinic referral included arterial-insufficient (37.4%), postoperative (25.9%), and mixed etiology (10.8%) wounds. The mean WHODAS 2.0 disability score was 35.0 (standard deviation = 16.0). One-hundred-and-nineteen (73.5%) patients had clinically significant disability. Patients reported they had the greatest difficulty walking a long distance (mean score = 4.2), standing for long periods of time (mean score = 3.6), taking care of household responsibilities (mean score = 2.7), and dealing with the emotional impact of their health problems (mean score = 2.5). In the two-weeks prior to presentation, 87 (52.7%) patients expressed concern over their wound(s) and 90 (55.6%) suffered a moderate amount or great deal of wound-related discomfort or distress. In adjusted ordinary least squares regression models, although WHODAS 2.0 disability scores varied with changes in wound volume (p = 0.03) and total revised photographic wound assessment tool scores (p<0.001), the largest decrease in disability severity was seen in patients with less wound-specific concerns and wound-related discomfort and distress. Discussion The majority of people at risk of limb loss report suffering a substantial burden of disability, pain, and wound-specific concerns. Research is needed to further evaluate the WHODAS 2.0 in a multicenter fashion among these patients and determine whether care and interventions may improve their PROs.

Chronic health conditions and disabilities interfere with major life activities, and these interferences are the result of complex interactions between health condition factors, psychological factors, personal factors, and socioenvironmental factors. The World Health Organization (WHO) International Classification of Functioning, Disability, and Health (ICF) framework is a biopsychosocial model that conceptualizes the experience of disability with attention to these interactions. The World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0) is an assessment tool developed to measure self-reported activity limitations and restrictions to participation experienced by individuals with disabilities independent of his or her medical diagnosis. In order to allow practitioners to effectively use this tool with individuals with various chronic illnesses and disabilities, the current study aimed to evaluate the measurement structure and psychometric properties of the WHODAS 2.0. A total of 945 adults with disabilities participated in the current study. Results support two-factor structure of this measurement tool with adequate reliability and construct validity. The WHODAS 2.0 is a valid, useful tool for rehabilitation counseling professionals to more effectively support adults with chronic health conditions and disabilities in achieving their psychosocial and employment success.
