Objective: Research concerning trans-disease processes aims to ascertain an underlying mechanism of several seemingly dissonant behaviors, pathological conditions, or both. The theory of reinforcer pathology posits that excessive delay discounting and the maladaptive overvaluation of a particular commodity underlie a variety of dysfunctional health behavior ranging from substance abuse to overeating and financial responsibility. The present study extends recent health behavior research by examining the extent delay discounting and food valuation correlate with engagement in a latent factor model of health and financial behaviors among healthy-weight participants and participants with obesity using the Health Behaviors Questionnaire. Method: A total of 700 participants (n = 340, body mass index [BMI] < 30; n = 360, BMI > 30 kg/m2) were recruited using Amazon Mechanical Turk. Participants completed a monetary delay discounting assessment, the Health Behaviors Questionnaire, and 2 measures of food valuation: Behavioral economic demand and the Power of Food Scale (PFS). Results: Utilizing structural equation modeling, both delay discounting and food valuation significantly correlated with engagement in health and financial behavior for both groups. The comparison of latent factors between groups indicated that participants with obesity were less likely to engage in multiple health behaviors and that these differences can be partially attributed to differences in delay discounting and food valuation. Conclusion: These results replicate previous research and further support the role of delay discounting as a trans-disease process. Given these results, trans-disease interventions, such as episodic future thinking, designed to specifically target reinforcer pathology may have a profound effect on overall functioning.

肥胖个体健康行为的强化病理模型。

目的：有关跨疾病过程的研究旨在确定几种看似不和谐的行为，病理条件或两者的潜在机制。强化剂病理学理论认为，过度延误折扣和特定商品的过高适应性过高是各种功能失调的健康行为的基础，从药物滥用到暴饮暴食和财务责任。本研究通过使用健康行为问卷调查健康体重参与者和肥胖参与者中参与健康和财务行为潜在因素模型的延误折扣和食品评估程度，扩展了最近的健康行为研究。方法：总共700名参与者（n = 340，体重指数[BMI] <30； n = 360，BMI> 30公斤/平方米）是使用Amazon Mechanical Turk招募的。参与者完成了货币延迟贴现评估，健康行为问卷和2种食品评估指标：行为经济需求和食品秤规模（PFS）。结果：利用结构方程模型，延迟折扣和食品评估都与两组的健康和财务行为密切相关。两组之间潜在因素的比较表明，肥胖参与者不太可能进行多种健康行为，这些差异可以部分归因于延误折扣和食品评估上的差异。结论：这些结果重复了先前的研究，并进一步支持了延迟贴现作为跨疾病过程的作用。鉴于这些结果，专门针对强化剂病理学设计的跨疾病干预措施（例如未来的未来思维）可能会对整体功能产生深远影响。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
