    Study Notes

    World Health Organization Disability Assessment Schedule 2.0 (WHODAS 2.0)

    • The adult self-administered version of WHODAS 2.0 is a 36-item measure that assesses disability in adults aged 18 years and older.
    • It has been validated across numerous cultures worldwide and demonstrated sensitivity to change.
    • WHODAS 2.0 assesses disability across six domains:
      • Understanding and communicating
      • Getting around
      • Self-care
      • Getting along with people
      • Life activities (household, work, and/or school activities)
      • Participation in society
    • If the adult individual is of impaired capacity, a knowledgeable informant may complete the proxy-administered version of the measure.

    WHODAS 2.0 Scoring Instructions

    • Each item on the self-administered version asks the individual to rate how much difficulty they have had in specific areas of functioning during the past 30 days.
    • There are two basic options for computing the summary scores for the WHODAS 2.0 36-item full version.
    • The simple scoring method sums the scores from each item without recoding or collapsing of response categories.
    • The scores assigned to each item are: "none" (1), "mild" (2), "moderate" (3), "severe" (4), and "extreme" (5).
    • The maximum total raw score is 180.
    • The simple scoring method is practical for hand-scoring and may be preferred in busy clinical settings or paper-and-pencil interview situations.

    Complex Scoring Method

    • Item-response-theory (IRT)-based scoring is a complex method of scoring that considers multiple levels of difficulty for each WHODAS 2.0 item.
    • IRT-based scoring takes into account the coding for each item response as "none," "mild," "moderate," "severe," and "extreme" separately.
    • A computer program is required to determine the summary score by differentially weighting the items and the levels of severity.

    Scoring Steps

    • Step 1: Recoded item scores are summed within each domain, converting response options 1-5 to a rate of 0-4, resulting in a total raw score of 144.
    • Step 2: All six domain scores are summed.
    • Step 3: The summary score is converted into a metric ranging from 0 to 100, where 0 = no disability and 100 = full disability.

    WHODAS 2.0 Domain Scores

    • WHODAS 2.0 produces domain-specific scores for six functioning domains:
      • Cognition
      • Mobility
      • Self-care
      • Getting along
      • Life activities (household and work/school)
      • Participation

    WHODAS 2.0 Population Norms

    DSM-5-TR Scoring and Interpretation Guidance

    • Clinicians review individual's responses during the clinical interview and record self-reported scores in the "Clinician Use Only" section.
    • Clinicians can override self-reported scores with corrected scores based on clinical interview and other available information.
    • Average domain and general disability scores are recommended for calculation and use.
    • Average scores are comparable to the WHODAS 5-point scale, ranging from none (1) to extreme (5).
    • Average scores were found to be reliable, easy to use, and clinically useful in the DSM-5 Field Trials.

    Calculating Average Scores

    • Average domain score is calculated by dividing the raw domain score by the number of items in the domain.
    • Example: If all items in the "understanding and communicating" domain are rated as moderate, the average domain score would be 18/6=3, indicating moderate disability.
    • Average general disability score is calculated by dividing the raw overall score by the number of items in the measure (36).

    Administering the WHODAS 2.0

    • Individuals should be encouraged to complete all items on the WHODAS 2.0.
    • If 10 or more items are left blank, the measure is considered invalid.

    Frequency of Use

    • The measure should be completed at regular intervals to track changes in an individual's level of disability over time.
    • The frequency of completion depends on the stability of the individual's symptoms and treatment status, as clinically indicated.
    • Consistently high scores on a particular domain may signal:
    • Significant and problematic areas for the individual
    • Need for further assessment and intervention
