Worker Role Interview

Abstract

The Worker Role Interview (WRI), known in Dutch as the Werknemersrol Interview, is a specialized, semi-structured assessment tool designed for use in vocational and occupational rehabilitation settings. Scored on a 4-point ordinal scale, the WRI systematically measures the influence of both psychosocial factors and environmental contexts on an individual’s capacity to return to work following illness or injury. The primary methodology involves a detailed discussion between the client and the occupational therapist, combining qualitative information gathered during the interview with quantitative data derived from observation within a work rehabilitation program.

The instrument’s goal is to facilitate a comprehensive analysis of various life and work aspects, ensuring that intervention planning addresses crucial internal motivators and external barriers related to the resumption of the worker role.

Purpose

The principal purpose of the Worker Role Interview is to identify and evaluate the complex interplay of internal (psychosocial) and external (environmental) factors that either support or impede a client’s ability to resume or maintain their worker role after a significant health event, such as a physical injury or chronic illness. It serves as a critical initial assessment tool in vocational rehabilitation settings to guide clinical reasoning and intervention planning.

By using a standardized, yet flexible, interview format, the instrument assists the occupational therapist in gaining an in-depth understanding of the client’s motivation, habits, values, and environmental supports specifically related to work. This information is crucial for developing individualized intervention plans focused on successful reintegration into the workforce and optimizing vocational rehabilitation outcomes.

Construct

The WRI measures constructs related to the client’s volition, habituation, and environment, which are central tenets of the Model of Human Occupation (MOHO). Specifically, it assesses how these factors impact the client’s identity and competence as a worker. The instrument is fundamentally concerned with psychosocial factors, including self-efficacy, personal causation, and perceived competence, alongside crucial environmental components such as support from family, supervisors, and the workplace culture.

The scale items are designed to elicit narrative responses that reveal the client’s internal readiness and external context for work. This holistic perspective ensures that rehabilitation planning addresses both the client’s internal state and the practical barriers present in their potential work environment, facilitating a comprehensive approach to return to work.

Validity

The WRI, as a widely used tool within occupational therapy, has established face validity and content validity due to its direct alignment with the theoretical constructs of the Model of Human Occupation. Studies supporting the various versions (V9.0 and V10.0) typically examine criterion validity by correlating WRI scores with objective measures of work participation or employment outcomes.

Research often focuses on the instrument’s ability to predict successful return to work outcomes across diverse clinical populations, including those with chronic pain, mental health conditions, and musculoskeletal disorders. Establishing strong concurrent and predictive validity is essential for its application in clinical decision-making regarding employment potential and long-term vocational success.

Reliability

The reliability of the WRI is primarily assessed through inter-rater reliability, given its nature as a scored semi-structured interview, where the therapist interprets and rates the responses. High inter-rater reliability is critical to ensure that scores are consistent regardless of the therapist administering the instrument, which is achieved through standardized training protocols.

Studies examining the WRI have generally reported acceptable to good inter-rater reliability, particularly for highly trained and experienced raters. Test-retest reliability, while less frequently reported due to the dynamic nature of the constructs being measured during rehabilitation, is also considered important for monitoring changes in the client’s worker role perception over time.

Factor Analysis

Published research concerning the revised versions of the WRI often includes factor analysis to confirm the underlying structure of the 4-point rating scale items. These analyses are crucial for confirming that the items group together conceptually as intended, reflecting the three core constructs: Volition, Habituation, and Environmental Factors.

Initial factor analytic studies support the instrument’s conceptual separation of internal (psychosocial) and external (environmental) influences on the worker role, providing empirical evidence that the WRI measures distinct yet related domains impacting occupational functioning and work readiness, consistent with the MOHO framework.

Instrument

Test Type: Semi-structured Interview / Inventory

Format: Scored on a 4-point ordinal scale (Likert-type rating applied by the therapist based on client narrative and observation).

Language Available: English, Dutch (Nederlandse versie: 1998), and various other international translations.

Population Group: Adults (Volwassenen)

Age Group: Typically 18 years and older.

Population Details: Individuals undergoing work rehabilitation or vocational assessment following illness, injury, or disability affecting their ability to perform the worker role. The assessment focuses on functions related to education, profession/work, and economic life.

Test Methodology: The assessment combines data gathered through direct questioning in a semi-structured interview format with observational data collected during a work or vocational rehabilitation program, providing a holistic view of the client’s work potential.

Items of the Worker Role Interview / Werknemersrol Interview

IMPORTANT: The following scale items must be preserved in their original language and must not be changed in any way.

The specific items of the Worker Role Interview (WRI) were not provided in the source content. The scale typically consists of 16 items grouped into subscales related to Volition, Habituation, and Environmental Supports/Barriers. Examples of domains assessed include:

• Personal Causation and Self-Efficacy
• Values related to work
• Interests and goals
• Habits and routines
• Physical environment
• Social environment (support from others)
