Abstract

Cognitive Behavior Therapy (CBT) for bulimia nervosa (BN) requires patient skill utilization (use of treatment skills) and skill acquisition (successful skill use) for symptom improvement. Treatment outcomes are unsatisfactory, possibly due to poor skill acquisition and utilization by post-treatment. Just-in-time adaptive interventions (JITAIs), momentary interventions delivered at opportunities for skill practice, may improve skill acquisition and utilization. Participants (N = 56 individuals with bulimia-spectrum eating disorders) completed electronic self-monitoring in CBT+ and received JITAIs or no JITAIs alongside 16 sessions of CBT. Feasibility, acceptability, target engagement, and treatment outcomes were evaluated. JITAIs demonstrated feasibility and acceptability. Treatment outcomes and target engagement did not differ between conditions. The lack of group differences in target engagement and treatment outcomes may be explained by skill use self-monitoring promoting skill utilization and acquisition or low statistical power. Our findings suggest that JITAIs are feasible and acceptable during CBT for BN and warrant additional study.

CBT+的一项随机对照试验：一项临床医生控制的、及时的、辅助干预的Bulimia谱系障碍。

神经性贪食症（BN）的认知行为疗法（CBT）需要患者利用技能（使用治疗技能）和获得技能（成功使用技能）来改善症状。治疗结果不令人满意，可能是由于治疗后技能获取和利用率低。即时适应性干预（JITAIs），即在技能实践机会提供的瞬时干预，可以提高技能的获取和利用。参与者（N = 56名患有贪食症谱系饮食障碍的个体）在CBT+中完成了电子自我监测，并在16次CBT的同时接受了JITAIs或不接受JITAIs。评估了可行性、可接受性、目标参与度和治疗结果。JITAI证明了其可行性和可接受性。不同情况下的治疗结果和目标参与度没有差异。在目标参与度和治疗结果方面缺乏群体差异的原因可能是技能使用自我监测促进了技能利用和获取，或者统计能力较低。我们的研究结果表明，在BN的CBT过程中，JITAI是可行和可接受的，值得进一步研究。

期刊介绍： For two decades, researchers and practitioners have turned to Behavior Modification for current scholarship on applied behavior modification. Starting in 1995, in addition to keeping you informed on assessment and modification techniques relevant to psychiatric, clinical, education, and rehabilitation settings, Behavior Modification revised and expanded its focus to include treatment manuals and program descriptions. With these features you can follow the process of clinical research and see how it can be applied to your own work. And, with Behavior Modification, successful clinical and administrative experts have an outlet for sharing their solutions in the field.
