A Study of the Psychometric Properties of the Work-Life Quality Questionnaire

The present study aims to examine the psychometric properties of the Work-Life Quality Questionnaire among cement company employees. Data were collected from 30 individuals, including 21 males and nine females. The questionnaire's validity was assessed using face validity (expert judgement) and internal consistency validity. The latter was evaluated by calculating Pearson's correlation coefficient between each item and the total score of the dimension to which it belongs and between each dimension and the overall questionnaire score. The reliability of the questionnaire was verified through the split-half method and Cronbach's alpha, with reliability coefficients computed at both the dimensional and total questionnaire levels. The findings confirmed that the Work Life Quality Questionnaire is valid in measuring its intended construct and demonstrated a good level of reliability and a high degree of stability in its results.
