Dialectical behavior therapy (DBT) can be considered the most effective treatment when attending to problem behaviors that define borderline personality disorder (BPD). This therapy employs chain analysis as the tool for accounting of contextual variables that maintain these behaviors. However, these detected variables are descriptive and temporal rather than strictly functional. That is, the role of contextual variables is analyzed regarding temporal relations with problem behavior but not in terms of contingency relations that allow showing their function. Thus, a functional approach to hypothesize these contingency relations between responses and the variables that control them was carried out. Behavior functional analysis was employed as a tool and functional hypotheses of the DSM-5-TR criteria for BPD were conducted. The conclusion is that the proposed approach can be combined with DBT chain analysis to elaborate more accurate functional hypotheses about cases displaying the behaviors defined in the diagnosis.

边缘性人格障碍的功能性方法

在处理边缘型人格障碍 (BPD) 的问题行为时，辩证行为疗法 (DBT) 可以被认为是最有效的治疗方法。这种疗法采用链分析作为工具来解释维持这些行为的情境变量。然而，这些检测到的变量是描述性的和时间性的，而不是严格的功能性变量。也就是说，上下文变量的作用是根据与问题行为的时间关系来分析的，而不是根据允许显示其功能的偶然关系来分析的。因此，采用函数方法来假设响应与控制它们的变量之间的这些应急关系。采用行为功能分析作为工具，并进行了 DSM-5-TR BPD 标准的功能假设。结论是，所提出的方法可以与 DBT 链分析相结合，以针对显示诊断中定义的行为的病例制定更准确的功能假设。
