This pilot study aimed to analyze the effects of an adapted dialectical behavior therapy (DBT) skills training group on problematic and adaptive eating behaviors in Brazilian obese individuals.
Thirty-one obese individuals were randomly assigned to 10 sessions of adapted DBT skills training (n = 14) or two months of a waiting list comparison condition (n = 17).
Attrition rates were similar to what's been found in comparable studies, with most dropouts happening at the beginning of the treatment. Results showed improvements in binge eating severity (d = 0.80) and depression (d = 0.82) compared to no treatment condition. After the intervention, adaptive eating and distress outcomes showed an improvement trend, reaching nonclinical levels for most participants in the intervention group. Large to moderate between-group effect sizes were observed, but none of those were statistically significant. Large within-group effect sizes were observed in the intervention group in binge eating severity (d = 1.34), intuitive eating (d = 1.33) and depression (d = 1.12). Medium effect sizes were observed in emotional eating (d = 0.73) and in emotion regulation (d = 0.72). Despite positive outcomes in other variables, mindful eating worsened after the intervention (d = 0.66).
These results are preliminary and require further replications with larger samples, yet they suggest that the intervention may be useful to improve distress outcomes and adaptive eating among obese people. Implications for clinical practice and recommendations for future research are discussed.

本试点研究旨在分析一种适应性辩证行为疗法（DBT）技能培训小组对巴西肥胖个体的问题性和适应性饮食行为的影响。
31名肥胖个体被随机分配到10节适应性DBT技能培训课程组（n = 14）或两个月的等待名单对照组（n = 17）。
损耗率与同类研究中的情况相似，大多数退出发生在治疗开始时。结果显示，与未治疗组相比，暴饮暴食严重程度（d = 0.80）和抑郁（d = 0.82）有所改善。干预后，适应性饮食和痛苦结果呈现改善趋势，干预组的大多数参与者达到了非临床水平。观察到组间效应大小为中等到较大，但均无统计学意义。干预组在暴饮暴食严重程度（d = 1.34）、直觉饮食（d = 1.33）和抑郁（d = 1.12）方面观察到较大的组内效应大小。在情绪化饮食（d = 0.73）和情绪调节（d = 0.72）方面观察到中等效应大小。尽管在其他变量上有积极结果，但干预后正念饮食恶化（d = 0.66）。
这些结果是初步的，需要更大样本的进一步重复研究，但它们表明该干预措施可能有助于改善肥胖人群的痛苦结果和适应性饮食。讨论了对临床实践的启示和对未来研究的建议。
