Assessing motivation for work environment improvements: internal consistency, reliability and factorial structure

Area of Science:

• Occupational Health Psychology
• Organizational Behavior
• Psychometrics

Background:

• Worker motivation is crucial for the success of workplace improvement initiatives.
• Existing tools may not adequately capture motivation for environmental enhancements.
• There is a need for a validated instrument to assess this specific type of motivation.

Purpose of the Study:

• To design and validate a questionnaire measuring workers' motivation for work environment improvements.
• To assess the reliability and factorial structure of the developed instrument.

Main Methods:

• Development of a novel questionnaire.
• Assessment of internal consistency and test-retest reliability.
• Exploration of the factorial structure using data from 113 employees.

Main Results:

• The questionnaire demonstrated high internal consistency (0.94) and total score reliability (0.84).
• Factor analysis identified three distinct factors explaining 61.6% of the total variance.
• The instrument shows strong psychometric properties.

Conclusions:

• The developed questionnaire is a reliable and valid tool for measuring motivation in workplace improvement contexts.
• This instrument can aid in optimizing intervention strategies and evaluating the effectiveness of investments in work environment enhancements.
