Abstract
Objectives: To examine the reliability and validity of the Japanese version of the Health Education Impact Questionnaire (heiQ-J) which measures the self-management ability for male workers with metabolic syndrome (MetS).
Methods: Between 2008 and 2012, a longitudinal survey was conducted for 525 men who received Specific Health Guidance (Tokutei Hoken Shido) at six sites from the Tokai to Kanto areas of Japan. heiQ-J was administered to the participants, and they were asked about their lifestyle using “Questionnaire on Specific Health Checkups” by the Ministry of Health, Labour and Welfare. The questionnaire was completed before and after the health guidance. Reliability analysis and factorial validity examination of heiQ-J were performed. Sensitivity was assessed on the basis of the relationship of the questionnaire with Specific Health Checkups. Changes in heiQ-J scores after the health guidance were examined using an effect size.
Results: The model GFI was 0.81, AGFI was 0.78, CFI was 0.84, and RMSEA was 0.060, and heiQ-J (model 2) was adopted with an error covariance set for 43 items in eight subscales. Comparison with heiQ-J showed the sensitivity to a healthy lifestyle of “Questionnaire on Specific Health Checkups”. Improvement was observed in approximately half of the participants in “health service navigation,” “skill and technique acquisition,” “self-monitoring and insight,” and “health-directed activity” after completing the health guidance (effect size ≧ 0.5).
Conclusion: The reliability and validity of heiQ-J (43 items) were confirmed as a metric for health guidance designed to improve metabolic syndrome. It suggests that the heiQ-J could be used in health guidance.
