This study applied a functional approach to the study of bingeing and purging behaviors. Based on a four-function theoretical model of bingeing and purging, it was hypothesized that these behaviors are performed because of their intrapersonally reinforcing (e.g., emotion regulation) and/or interpersonally reinforcing (e.g., help-seeking, attention-getting behavior) properties. Participants were 298 adult females who had engaged in bingeing or purging in the last 3 months and who provided data via an online survey of these behaviors. Confirmatory factor analyses revealed support for a four-function model of bingeing and purging in which people use these behaviors for intrapersonal reinforcement functions and also for interpersonal reinforcement. Understanding the functions of binge eating and purging has direct implications for assessment and treatment of these behaviors.
本研究采用功能方法研究暴食和清肠行为。基于暴食和清肠的四功能理论模型，研究假设这些行为是因为其具有个体内强化（例如情绪调节）和/或人际强化（例如寻求帮助、引起注意的行为）的特性。参与者为 298 名在过去 3 个月内有暴食或清肠行为的成年女性，她们通过在线调查提供了这些行为的数据。验证性因素分析支持暴食和清肠的四功能模型，即人们使用这些行为来实现个体内强化功能，也用于人际强化。理解暴食和清肠的功能对这些行为的评估和治疗具有直接意义。
