This study aimed to adapt the Psychological Food Involvement Scale (PFIS) to Turkish culture and test its validity and reliability. The PFIS measures individuals' psychological, emotional, and social relationships with food, which significantly impact eating behaviors and health.
The study was conducted with 478 participants aged 18-65. The PFIS underwent a six-stage translation and cultural adaptation process. Data collection was carried out via Google Forms, with participants completing a general information form, PFIS, and the Addiction-like Eating Behavior Scale (ALEBS). Reliability was assessed using the test-retest method. SPSS 24 was used for statistical evaluation, including internal consistency coefficient calculations, factor analysis, and correlation tests.
The Kaiser-Meyer-Olkin value was 0.94, indicating an adequate sample size, and Bartlett's test of sphericity was significant (p < 0.05). Exploratory factor analysis revealed a four-factor structure explaining 79% of the variance, with factor loadings > 0.40 and eigenvalues > 1. Confirmatory factor analysis showed good fit indices: χ2 /sd = 2.28, GFI = 0.95, AGFI = 0.93 CFI = 0.98, NFI = 0.94, RMSEA = 0.05, SRMR = 0.04). Internal consistency analysis showed high reliability, with Cronbach's Alpha coefficients ranging from 0.86 to 0.94 across subscales.
The Turkish version of the PFIS was found to be a valid and reliable tool for assessing psychological food involvement in the studied sample of the Turkish adult population.
本研究旨在使心理性食物卷入量表（PFIS）适用于土耳其文化，并检验其有效性和可靠性。PFIS 测量个体与食物的心理、情感和社会关系，这些关系对饮食行为和健康有显著影响。
该研究对478名年龄在18至65岁之间的参与者进行。PFIS 经历了六个阶段的翻译和文化适应过程。通过谷歌表单进行数据收集，参与者需完成一份一般信息表、PFIS 和成瘾样饮食行为量表（ALEBS）。使用重测法评估信度。使用 SPSS 24 进行统计评估，包括计算内部一致性系数、因子分析和相关性检验。
Kaiser-Meyer-Olkin 值为0.94，表明样本量充足，Bartlett 球形检验具有显著性（p < 0.05）。探索性因子分析揭示了一个四因子结构，解释了79%的方差，因子载荷 > 0.40且特征值 > 1。验证性因子分析显示拟合指数良好：χ2 /sd = 2.28，GFI = 0.95，AGFI = 0.93，CFI = 0.98，NFI = 0.94，RMSEA = 0.05，SRMR = 0.04）。内部一致性分析显示信度较高，各分量表的 Cronbach's Alpha 系数在0.86至0.94之间。
发现 PFIS 的土耳其语版本是评估土耳其成年人群体样本中心理性食物卷入的有效且可靠的工具。
