This study analyzes the interobserver agreement and hypothesis-based known-group validity of the Therapist's Verbal Behavior Category System (SISC-INTER). The SISC-INTER is a behavioral observation protocol comprised of a set of verbal categories representing putative behavioral functions of the in-session verbal behavior of a therapist (e.g., discriminative, reinforcing, punishing, and motivational operations). The complete therapeutic process of a clinical case of an individual with marital problems was recorded (10 sessions, 8 hours), and data were arranged in a temporal sequence using 10-min periods. Hypotheses based on the expected performance of the putative behavioral functions portrayed by the SISC-INTER codes across prevalent clinical activities (i.e., assessing, explaining, Socratic method, providing clinical guidance) were tested using autoregressive integrated moving average (ARIMA) models. Known-group validity analyses provided support to all hypotheses. The SISC-INTER may be a useful tool to describe therapist-client interaction in operant terms. The utility of reliable and valid protocols for the descriptive analysis of clinical practice in terms of verbal behavior is discussed.
本研究分析了治疗师言语行为分类系统（SISC-INTER）的观察者间一致性和基于假设的已知组有效性。SISC-INTER 是一种行为观察协议，由一组代表治疗师会话中言语行为的假设行为功能的言语类别组成（例如，辨别、强化、惩罚和动机操作）。记录了一个有婚姻问题的个体的完整临床案例治疗过程（10 次会话，8 小时），并使用 10 分钟的时间段按时间顺序排列数据。使用自回归综合移动平均（ARIMA）模型测试了基于 SISC-INTER 编码在常见临床活动中（即评估、解释、苏格拉底法、提供临床指导）预期表现的假设。已知组有效性分析支持了所有假设。SISC-INTER 可能是一种有用的工具，可以用操作性术语描述治疗师-患者的互动。讨论了可靠和有效的协议在言语行为方面对临床实践描述性分析的效用。
