Abstract
The Occupational Work Ethic Inventory (OWEI), originally developed by Petty (1991), is a 50-item self-report instrument designed to measure the intrinsic aspects of an individual’s work behavior and attitudes within the workplace. It provides a standardized measure of work ethic, which is crucial for educators preparing students for the transition from school to work, and for organizations assessing employee readiness and performance. The scale has been extensively validated across various professional groups.

Purpose
The primary purpose of the OWEI is to quantify the intrinsic dimension of an individual’s professionalism and commitment—often referred to as the work ethic. By assessing key behavioral factors, the inventory offers a robust research foundation for vocational and technical educators. This allows them to better structure curricula and training programs aimed at enhancing the employability skills required by modern industry.
Furthermore, the OWEI assists organizations in understanding the foundational attitudes employees bring to their roles. The original validation efforts focused on providing clear, factor-based evidence of the components that constitute a strong occupational work ethic, offering practical metrics for both academic and organizational use.
Construct
The OWEI measures the psychological construct known as the Occupational Work Ethic. This construct is defined by a set of intrinsic values, attitudes, and behaviors essential for success in the modern workplace. It moves beyond simple job skills to assess underlying habits, values, and reliability.
The scale operationalizes this construct through four distinct, empirically derived factors: Initiative, Interpersonal Skills, Dependability, and the careful treatment of negative or reversed items. These factors collectively capture the multifaceted nature of professional dedication and responsibility.
Validity
The validity of the OWEI was established through rigorous, multi-stage procedures. Content validity relied on an extensive review of existing literature concerning work attitudes, work values, and work habits. Items were carefully selected based on this review and subsequently evaluated by a panel of subject matter experts.
To ensure structural integrity, a second panel of experts repeatedly sorted the initial items into conceptual categories until a high level of consensus was achieved. This process yielded four core conceptual categories: dependable, ambitious, considerate, and cooperative. Additionally, several subsequent factor analytic studies were conducted to establish robust construct validity, confirming that the scale measures the intended underlying psychological dimensions.
Reliability
The internal consistency of the Occupational Work Ethic Inventory has demonstrated strong reliability across multiple studies. In the initial pilot study, the internal consistency, measured using the Cronbach’s alpha coefficient, was reported at an excellent level of 0.95.
Further validation studies have consistently supported this high level of reliability, with reported alpha coefficients generally ranging from 0.90 (in Hatcher’s 1993 dissertation) up to the original high of 0.95 (reported by Hill). These findings indicate that the scale items consistently measure the same underlying construct across diverse samples.
Factor Analysis
The structural integrity of the OWEI was confirmed using a principal components factor analysis followed by a varimax orthogonal rotation. This statistical methodology yielded a clear, four-factor structure for the 50-item instrument, supporting the multidimensional nature of the occupational work ethic construct.
The four empirically derived factors and their respective item counts are:
- Interpersonal Skills: 15 items (items 17, 22, 28, 29, 31, 32, 33, 37, 41, 42, 43, 46, 47, 48, and 50).
- Initiative: 16 items (items 5, 6, 7, 10, 11, 14, 15, 18, 20, 27, 35, 36, 38, 40, 45, and 49).
- Dependability: 7 items (items 1, 3, 4, 8, 12, 16, and 23).
- Reversed Items: 10 items (items 9, 13, 21, 24, 25, 26, 30, 34, 39, and 44).
The original research reported detailed factor loadings, item means, and standard deviations to support the robustness of this factor solution.
