The psychological interview is a complex system which emerges from the interaction of its components, i.e., the patient and the psychologist; therefore, it is presumed to display a fractal structure whose dimension defines its level of complexity. This paper presents a pilot study for a new evaluative methodology of the fractal dimension in the psychological interview: the analysis of 4 psychological interviews led to the determination of their fractal dimension, defined by the amount of verbal content produced. The conversational turn-taking naturally established in the patient-psychologist dyad divides the verbatim transcripts of the sessions into Relational Verbal Units (RVU), whose sizes are determined by the number of words which composes them. It was observed that the distribution of the RVUs in a size/frequency graph follows a power law distribution, from which it was possible to assess the Relational Fractal Dimension (RFD) of the interviews. The values obtained range from a minimum of 1.39 to a maximum of 1.50, an indicative range of self-organized criticality. Recursion is the simple process behind complexity, and it defines fractal patterns; the fractal dimension of a system characterizes its level of complexity, and its application in psychotherapy describes the therapeutic relationship as a nonlinear dynamic system endowed with self-organization and self-similarity.
心理访谈是一个复杂的系统，它是由其组成部分，即患者和心理学家的相互作用而产生的；因此，它被认为具有分形结构，其维度定义了其复杂程度。本文提出了一种心理访谈分形维数的新评估方法的初步研究：对 4 次心理访谈的分析导致了它们的分形维数的确定，该维数由产生的言语内容的数量来定义。患者-心理学家对偶体中自然建立的会话轮流制将会话的逐字记录划分为关系言语单位（RVU），其大小由组成它们的单词数量决定。观察到 RVU 在大小/频率图中的分布遵循幂律分布，从中可以评估访谈的关系分形维数（RFD）。所得到的值范围从最小的 1.39 到最大的 1.50，这是自组织临界性的指示范围。递归是复杂性背后的简单过程，它定义了分形模式；系统的分形维数描述了其复杂程度，其在心理治疗中的应用将治疗关系描述为具有自组织和自相似性的非线性动力系统。
