Previous studies have suggested that response-style strategies (rumination, problem-solving, and distraction) can be risk or protective factors for the development of abnormal eating behaviors/attitudes (AEB) during adolescence. However, due to limited empirical data regarding the prospective effects of these strategies on AEB, further research is needed to clarify their role in developing AEB in adolescence.
This study investigated the one-year lagged effects of response-style strategies on AEB in 24,883 fourth- to eighth-grade students in Japan between 2015 and 2019 using a cross-lagged panel model. Depressive symptoms and body mass index (BMI), which are reported to relate to AEB, were also included in the analytic model. The students self-reported their levels of response-style strategies, AEB, and depressive symptoms. We also evaluated BMI based on teachers' reports.
We found that greater rumination significantly predicted more severe AEB in the following year among students from all grades, with small to moderate effect sizes. In addition, distraction significantly predicted more severe binge eating/purging behaviors, but with very weak small effect sizes. Problem-solving did not predict any level of AEB. Furthermore, we observed significant reciprocal relationships between response-style strategies, AEB, and depressive symptoms. Positive reciprocal associations between BMI and AEB were also found except for some intervals.
We concluded that a decrease in rumination is critical to alleviating mental health problems, such as AEB and depressive symptoms, during adolescence. This suggests that interventions to reduce the level of rumination should be conducted in the early stages of adolescence.

先前的研究表明，应对方式策略（反刍、解决问题和分心）可能是青少年异常饮食行为/态度（AEB）发展的风险因素或保护因素。然而，由于关于这些策略对AEB的前瞻性影响的实证数据有限，需要进一步研究以阐明它们在青少年AEB发展中的作用。
本研究使用交叉滞后面板模型，调查了2015年至2019年期间日本24,883名四至八年级学生应对方式策略对AEB的一年滞后效应。分析模型中还纳入了据报道与AEB相关的抑郁症状和体重指数（BMI）。学生自我报告他们的应对方式策略、AEB和抑郁症状水平。我们还根据教师报告评估了BMI。
我们发现，在所有年级的学生中，更多的反刍显著预测了次年更严重的AEB，效应大小为小到中等。此外，分心显著预测了更严重的暴饮暴食/清除行为，但效应大小非常小且微弱。解决问题并不能预测任何水平的AEB。此外，我们观察到应对方式策略、AEB和抑郁症状之间存在显著的相互关系。除了某些时间段外，还发现BMI与AEB之间存在正相关的相互关系。
我们得出结论，减少反刍对于缓解青少年时期的心理健康问题（如AEB和抑郁症状）至关重要。这表明应在青少年早期阶段开展减少反刍水平的干预措施。
