Orthorexia nervosa is a new type of disordered eating, characterized by an unhealthy fixation on healthy food. Those who suffer from it are showing compulsive behaviors and increasing dietary restrictions, that can lead to anxiety and physical health problems. Measuring tools for estimating the seve rity of its symptoms are available in Hungary only to a limited extent. The aim of this study was to adapt the Eating Habits Questionnaire's revised version (EHQ-R) to Hungarian, and to perform a psychometric analysis, moreover, to explore the demographic features of orthorexic tendencies.
The cross-sectional online questionnaire included adults who perform physical exercize regularly (n = 175, 29% male; mean age 35.4 [SD = 7.59] years).
sociodemographic data, anthropometric data (body - weight, height), EHQ-R, ORTO-11-Hu questionnaires.
Confirmatory factor analysis supported the EHQ-R's five-factor theoretical structure (c2 (395) = 856.2; p < 0.001; CFI = 0.914; TLI = 0.906; RMSEA = 0.082 [CI 90: 0.074-0.089]). Both the internal reliability of the scales (Cronbach-a = 0.75-0.87) and its consistency over time (r / r = 0.67-0.86) were adequate. The construct validity of the questionnaire is supported by the close correlation of the scales with the ORTO-11-Hu questionnaire (r / r = | 0.63-0.68 |). Regarding gender differences, women scored higher than men on the EHQ-R's Rigidity subscale (t [173] = -1.807; p = 0.073). Age showed a significant, weak, negative relationship with the Negative Emotionality (r = -0.18; p = 0.017) and Time Impairment (r = -0.21; p = 0.005) subscales.
The EHQ-R has proven to be a reliable and valid measurement tool, thus, we recommend utilizing it as it can provide a quick and valid assessment about the severity of orthorexia symptoms, enabling appropriate interventions.
正食癖是一种新型的饮食失调症，其特征是对健康食品有着不健康的执着。患有此病的人表现出强迫行为和日益严格的饮食限制，这可能导致焦虑和身体健康问题。在匈牙利，用于评估其症状严重程度的测量工具非常有限。本研究的目的是将饮食习惯问卷修订版（EHQ-R）改编为匈牙利语版本，并进行心理测量分析，此外，还要探究正食癖倾向的人口统计学特征。
横断面在线问卷的对象包括有规律进行体育锻炼的成年人（n = 175，男性占29%；平均年龄35.4岁[标准差 = 7.59]）。
社会人口学数据、人体测量数据（体重、身高）、EHQ-R问卷、ORTO-11-Hu问卷。
验证性因素分析支持EHQ-R的五因素理论结构（卡方值(395) = 856.2；p < 0.001；比较拟合指数 = 0.914；塔克-刘易斯指数 = 0.906；近似误差均方根 = 0.082 [90%置信区间：0.074 - 0.089]）。量表的内部信度（克朗巴哈系数α = 0.75 - 0.87）及其随时间的一致性（重测相关系数r = 0.67 - 0.86）均足够。问卷的结构效度得到量表与ORTO-11-Hu问卷紧密相关性的支持（相关系数r = | 0.63 - 0.68 |）。关于性别差异，女性在EHQ-R的僵化子量表上得分高于男性（t [173] = -1.807；p = 0.073）。年龄与消极情绪子量表（r = -0.18；p = 0.017）和时间障碍子量表（r = -0.21；p = 0.005）呈显著、微弱的负相关。
EHQ-R已被证明是一种可靠且有效的测量工具，因此，我们建议使用它，因为它可以对正食癖症状的严重程度提供快速有效的评估，从而实现适当的干预。
