A questionnaire survey on HEH (attitudes and behaviors) was conducted with 375 community-dwelling older people (aged 60 years or older). We used a 12-item modified version of the HEH scale by Kohsaka et al. (Bulletin of Social Medicine, Vol. 27, No.2, pp.1–10, 2010). Of the 375 questionnaires distributed to community-dwelling older people, data without missing responses from 355 respondents were analyzed (valid response rate: 94.6%). Based on the item analysis and exploratory factor analysis (maximum likelihood method and Promax rotation), 10 items related to 3 factors (5 items for “health orientation,” 3 items for “food variety and balance,” and 2 items for “co-eating”) were extracted. Confirmatory factor analysis revealed that a second-order factor model by 3 first-order factors had sufficient fit to the data (GFI = 0.97,CFI = 0.97,RMSEA = 0.04). Cronbach’s alpha coefficients for the total and its 3 subscales ranged from 0.67 to 0.79, ensuring acceptable internal consistency. In addition, construct validity was supported by hypothesis testing to determine whether the scale’s scores correlated with other scale scores/indicators in theoretically expected ways. These results suggest that the HEH scale has a sufficient level of validity and reliability. The scale is expected to be used in salutogenic research on healthy eating habits in future., P(論文)}, pages = {57--68}, title = {高齢期の健康的な食関連習慣尺度の妥当性と信頼性の検証 : 健康生成論に基づくアプローチ}, volume = {28}, year = {2022}, yomi = {サワダ, ヨウイチ and ヤジマ, ユウキ and サカノ, ジュンコ} }
