The assessment of dietary intakes and habits using reliable and youth-specific measurement tools during adolescence is essential. The aim of the present study was to culturally adapt and investigate the psychometric properties of the Persian version of the food preferences questionnaire (Persian-FPQ) among Iranian adolescents. This methodological cross-sectional study was conducted among 452 Persian-speaking adolescents, living in Isfahan, Iran. Translation of the FPQ was performed using forward-backward method. Intra Class Correlation (ICC) and Cronbach's α were used to assess test-retest reliability and internal consistency, respectively. Construct validity was investigated by using exploratory factor analysis (EFA). Divergent validity was determined using correlation analysis with Kessler Psychological Distress Scale (K-10). Known-group validity was assessed based on differences in mean food preference score between boys and girls and different categories of body mass index (BMI). The internal and external reliabilities for the Persian-FPQ were in the range of good to excellent in all domains (Cronbach's α: 0.76-0.96 and ICCs: 0.982-0.998). Boys had higher scores of food preferences than girls, indicating good known-group validity. Construct validity evaluated by EFA led to extraction of seven factors ("Vegetables", "Fruit", "Dairy", "Snacks", "Meat/Fish", "Starches" and "Miscellaneous foods"), explaining 37.8% of the variance. Divergent validity revealed significant negative correlations between five sub-scales of the Persian-FPQ and psychological distress. The Persian version of the FPQ is a reliable and valid instrument with applicability in a broad range of the population of Persian-speaking adolescents for assessing food preferences in community-based research projects.
使用可靠且针对青少年的特定测量工具评估青少年的饮食摄入量和习惯至关重要。本研究的目的是对伊朗青少年进行文化适应性调整,并研究波斯语版食物偏好问卷(Persian-FPQ)的心理测量特性。这是一项在伊朗伊斯法罕市进行的方法学横断面研究,共纳入 452 名讲波斯语的青少年。FPQ 的翻译采用正向-反向翻译法。使用组内相关系数(ICC)和克朗巴赫α系数分别评估重测信度和内部一致性。通过探索性因子分析(EFA)评估结构效度。通过与 Kessler 心理困扰量表(K-10)的相关性分析来确定离散效度。基于男孩和女孩之间以及不同体重指数(BMI)类别之间食物偏好得分的差异来评估已知组有效性。波斯语-FPQ 在所有领域的内部和外部可靠性均处于良好至优秀水平(克朗巴赫α:0.76-0.96,ICC:0.982-0.998)。男孩的食物偏好得分高于女孩,表明具有良好的已知组有效性。通过 EFA 评估的结构效度得出了七个因素(“蔬菜”、“水果”、“乳制品”、“零食”、“肉类/鱼类”、“淀粉”和“杂项食品”),可解释 37.8%的方差。离散效度显示,波斯语-FPQ 的五个子量表与心理困扰之间存在显著负相关。波斯语版 FPQ 是一种可靠且有效的工具,适用于广泛的波斯语青少年群体,可用于评估基于社区的研究项目中的食物偏好。
