Purpose

The instrument can be administered to assess a client’s psychological ability to return to work. Additionally, the DWA determines client’s level of participation in the rehab process. This individual assessment, consisting of a patient self-report and a professional assessment, assists with dialogue between a client’s employer and healthcare professional. The DWA addresses 5 MOHO related dimensions assessing readiness to return to work.

Key Descriptions

  • From our research, the DWA was administered in an outpatient psychiatric rehab center. (Linddhal, 2007)
    Two sections: one for the client to complete (patient self-report) and the other for the clinician (professional assessment), with 34 items each; divided into five dimensions:
    (1) personal causation, values, and interest (nine items),
    (2) roles and habits (eight items),
    (3) physical ability (four items),
    (4) organizational and problem-solving ability (six items), and
    (5) communication and interaction ability (seven items)
    Client’s level of awareness and perceived performance capacity against work is scored on a five-point Likert scale: ranging from “Low level” to “High level” (Norrby and Linddahl, 2006).

Number of Items

There are 34 items in the individual self-assessment.

Equipment Required

  • Questionnaire & Pencil

Test/Retest Reliability

  • Workers with long-term disability due to psychiatric or psychosocial problems (Norrby and Linddahl, 2006; n = 34; mean age = 40.9 years; mean number of years since last employment = 3.9 years). Spearman Rank Correlation
    • 3 items (r = 0.26-0.50)
    • 21 items (r = 0.51-0.75)
    • 9 items (r = 0.75-1.0)
    • 1 item (r = 0.90-1.0)
  • Psych Rehab Population (Linddhal, 2007) Spearman Rank Correlation used to determine clients perception of issues related to work ability: testing measurement error
    • Test-retest (r = 0.51-0.75)

Interrater/Intrarater Reliability

  • Workers with long-term disability due to psychiatric or psychosocial problems (Norrby and Linddahl, 2006; n = 34; mean age = 40.9 years; mean number of years since last employment = 3.9 years)
    • Excellent reliability: Percentage of Agreement > 75%
    • Interrater reliability in 15 items: (100%)
      • Personal causation, values, and interest questions: 5 items (1, 3, 4, 5, 6)
      • Roles and habits questions: 3 items (10, 12, 17)
      • Physical ability questions: 1 items (21)
      • Organizational and problematic solubility questions: 3 items (23, 25, 27)
      • Communication-interaction ability questions: 3 items (30, 31, 34)
    • Interrater reliability in 12 items: (93.8%)
      • Personal causation, values, and interest questions: 1 item (8)
      • Roles and habits questions: 4 items (11, 13, 15, 16)
      • Physical ability questions: 1 item (19)
      • Organizational and problematic solubility questions: 2 items (22, 24)
      • Communication-interaction ability questions: 4 items (28, 29, 32, 33)
    • Interrater reliability in 7 items: (75%-87.5%)
      • Personal causation, values, and interest questions: 3 items (2, 7, 9)
      • Roles and habits questions: 1 item (14)
      • Physical ability questions: 2 items (18, 20)
      • Organizational and problematic solubility questions: 1 item (26)
      • Communication-interaction ability questions: 0 items
  • Psych Rehab Population (Linddhal, 2007; n = 34; mean age = 40.9 years; mean number of years since last employment = 3.9 years) Percentage of Agreement utilized
  • Excellent reliability ranging from 93.1% - 96.5%

Construct Validity

Workers with long-term disability due to psychiatric or psychosocial problems

(Linddahl et al., 2003; n = 126; age range = 20-59; those involved in work during the last year = 19%)

  • Construct validity of the DWA Scale for personal causation, values, and interests assessed by clients and professionals (RMSError = 0.12, 0.13 respectively)
  • Construct validity of the DWA Scale for roles and habits, values, and interests assessed by clients and professionals (RMSError = 0.15)
  • Construct validity of the DWA Scale for physical ability assessed by clients and professionals (RMSError = 0.15, 0.17 respectively)
  • Construct validity of the DWA Scale for organizational and problem-solving ability assessed by clients and professionals (RMSError = 0.13, 0.14 respectively)
  • Construct validity of the DWA Scale for communication ability assessed by clients and professionals (RMSError = 0.15)
  • Construct validity of the DWA Scale for physical ability assessed by clients and professionals (RMSError = 0.15, 0.17 respectively)

Psych Rehab Population: (Linddahl, 2007; n = 126; age range = 20-59; those involved in work during the last year = 19%)

DWA demonstrates validity by measuring work capacity and ability to return to work. DWA’s 5 scales correlate with an increase in the 34 tested items.
