This study evaluated the reliability and validity of the Japanese version of the Body Talk Scale (BTS), designed to measure negative fat talk, negative muscle talk, and positive body talk. The study also explored the longitudinal associations between each body talk category and body dissatisfaction. We conducted two separate studies among university students in Japan. Separate confirmatory factor analyses for female and male data indicated that the initially proposed three-factor model demonstrated an acceptable fit, whereas the bi-factor model provided a better fit. The Japanese BTS showed good construct validity, acceptable to adequate internal consistency, and test-retest reliability within 2 weeks. A four-week longitudinal study involving 386 women and 216 men (mean age = 19.22 and 19.62, respectively) revealed that negative fat talk predicted an increase in the discrepancy between the thin ideal body image and the actual body image among women. In contrast, positive body talk was linked to reduced body dissatisfaction and body image discrepancy in women. There were no such significant associations in men. These findings support the use of the Japanese BTS as a valuable instrument for future research on the intrapersonal and interpersonal effects of various types of body talk.
本研究评估了日语版身体谈话量表（BTS）的信度和效度，该量表旨在测量负面身材谈论、负面肌肉谈论和正面身体谈论。本研究还探讨了每种身体谈话类别与身体不满之间的纵向关联。我们在日本大学生中进行了两项独立研究。对女性和男性数据进行的单独验证性因素分析表明，最初提出的三因素模型显示出可接受的拟合度，而双因素模型提供了更好的拟合度。日语版BTS显示出良好的结构效度、可接受至充分的内部一致性以及两周内的重测信度。一项为期四周的纵向研究涉及386名女性和216名男性（平均年龄分别为19.22岁和19.62岁），结果显示，负面身材谈论预示着女性理想瘦身材形象与实际身体形象之间的差异会增加。相比之下，正面身体谈论与女性身体不满和身体形象差异的减少有关。男性中不存在此类显著关联。这些发现支持将日语版BTS用作未来研究各类身体谈话的人际和人际间影响的有价值工具。
