[Development of a Wellness Index for Workers]

Area of Science:

• Occupational Health
• Psychometrics
• Workplace Wellness

Background:

• Worker wellness is crucial for productivity and organizational success.
• Existing measures may not comprehensively capture multifaceted aspects of worker well-being.
• Developing a validated instrument is essential for accurate assessment.

Purpose of the Study:

• To develop and validate the Wellness Index for Workers (WIW).
• To assess the psychometric properties (validity and reliability) of the WIW.
• To provide a tool for evaluating workers' overall wellness.

Main Methods:

• Instrument development involved framework construction, item generation, content validation by experts, and psychometric testing.
• Confirmatory factor analysis was used to examine construct, convergent, and discriminant validity.
• Reliability was assessed using Cronbach's alpha with data from 494 workers.

Main Results:

• The final WIW consists of 18 items, supporting a five-factor model: physical, emotional, social, intellectual, and occupational wellness.
• Confirmatory factor analysis demonstrated acceptable model fit, supporting construct, convergent, and discriminant validity.
• The instrument achieved a high reliability coefficient of .91 (Cronbach's alpha).

Conclusions:

• The Wellness Index for Workers (WIW) is a valid and reliable measure for comprehensively assessing worker wellness.
• The WIW can inform the development of targeted workplace wellness programs.
• This validated index offers a robust tool for occupational health research and practice.
