Construct Validity and Reliability of the Work Environment Assessment Instrument WE-10

Area of Science:

• Psychology
• Organizational Behavior
• Industrial-Organizational Psychology

Background:

• Assessing the work environment is crucial for understanding employee well-being and organizational effectiveness.
• Existing instruments may not comprehensively capture the multifaceted nature of the work environment.
• Integrating quality of life (QoL), quality of work life (QoWl), and organizational climate (OC) offers a holistic perspective.

Purpose of the Study:

• To validate a novel instrument designed to measure the work environment as a singular construct.
• To assess the construct validity and reliability of the integrated work environment instrument.
• To provide a psychometrically sound tool for evaluating QoL, QoWl, and OC.

Main Methods:

• Exploratory Factor Analysis (EFA) was employed to test construct validity.
• Cronbach's alpha was utilized to determine the instrument's reliability.
• Commonality analysis and varimax rotation were applied to refine the factor structure.

Main Results:

• The EFA yielded a Kaiser-Meyer-Olkin (KMO) value of 0.917, indicating data suitability for factor analysis.
• Bartlett's test of sphericity was significant (χ² = 7465.349, Df = 1225, p ≤ 0.000).
• The instrument's factor structure was refined from 14 to 10 factors, with high commonality for most items (all > 0.5, except one).
• Reliability analysis showed high internal consistency, with Cronbach's alpha values ranging from 0.953 to 0.956.

Conclusions:

• The developed instrument demonstrates robust construct validity.
• The instrument exhibits excellent reliability for measuring the work environment.
• This validated tool offers a comprehensive approach to assessing work environment factors, including QoL, QoWl, and OC.
