Construction of a short form of the healthy eating behaviour inventory for the Japanese population.

Abstract

INTRODUCTION The present study constructed a short form of the Healthy Eating Behavior Inventory suitable for use in the Japanese culture (HEBI-J) and confirmed the scale's preliminary reliability and validity. METHODS In Study 1, Japanese adults (N=75) completed a free-response questionnaire about healthy eating behaviours. Thematic analysis was used to identify three factors-balance, pattern, and restriction-associated with healthy eating behaviours and 12 items related to these healthy eating behaviours. In Study 2, Japanese office workers (N=784) completed two questionnaires regarding 12 items of healthy eating behaviours and the dietary stages of change. RESULTS Confirmatory factor analysis demonstrated that the three-factor model was appropriate (GFI=.94, AGFI=.90, CFI=.90, RMSEA=.08, SRMR=.53). Reliability was confirmed by alpha coefficients and the Spearman-Brown formula. Concurrent validity was confirmed by the relationship between the healthy eating stages. CONCLUSIONS This study demonstrated the preliminary reliability and validity of the HEBI-J.
