In this study, we tested potential mediators that may explain change in depressive symptoms following exposure to a food-related behavioral activation intervention (F-BA). These included behavioral activation, avoidance and rumination, eating styles, body mass index, and dietary behavior at baseline and 3-month and 12-month follow-up. The trial used a community sample of 1,025 overweight adults with elevated depressive symptoms without current major depression. Participants were randomly assigned to one of four trial arms: either daily nutritional supplements (vs. placebo) alone or in combination with F-BA (vs. no F-BA) over 12 months. Although F-BA did not significantly reduce depressive symptoms (standardized regression coefficient [b] = −0.223, SE = 0.129; p = .084), significant mediators included emotional eating (b = −0.028, SE = 0.014; p = .042) and uncontrolled eating (b = −0.039, SE = 0.016; p = .013), suggesting that learning adaptive responses to emotional and food cues may underlie effects of F-BA on depressive symptoms.

在这项研究中，我们测试了潜在的介质，这些介质可能解释了暴露于食物相关的行为激活干预（F-BA）后抑郁症状的变化。这些包括行为激活，避免和反省，饮食方式，体重指数以及基线，3个月和12个月的随访中的饮食行为。该试验使用了1025名超重成年人的社区样本，这些成年人有较高的抑郁症状，而目前没有严重的抑郁症。参与者被随机分配到四个试验组之一：在12个月内单独使用每日营养补充剂（相对于安慰剂）或与F-BA组合（相对于F-BA）。尽管F-BA并未显着减轻抑郁症状（标准回归系数[ b ] = -0.223，SE = 0.129；p= .084），重要的调解人包括情绪饮食（b = -0.028，SE = 0.014; p = .042）和不受控制的饮食（b = -0.039，SE = 0.016; p = .013），这表明学习适应性饮食对情绪和食物暗示可能是F-BA对抑郁症状的影响的基础。
