To determine whether or not different therapies have distinct patterns of change, it is useful to investigate not only the end result of psychotherapy (outcome) but also the processes by which outcomes are attained. The present study subjected data from the National Institute of Mental Health Treatment of Depression Collaborative Research Program to survival analyses to examine whether the process of psychotherapy, as conceptualized by the phase model, differed between psychotherapy treatment approaches. Few differences in terms of progression through phases of psychotherapy were identified between cognitive behavior therapy and interpersonal therapy. Additionally, results indicate that phases of psychotherapy may not represent discrete, sequentially invariant processes.
为了确定不同的治疗方法是否具有不同的变化模式，不仅要研究心理治疗的最终结果（结果），还要研究达到结果的过程。本研究对国家心理健康研究所抑郁症治疗合作研究计划的数据进行了生存分析，以检查心理治疗过程（如阶段模型所概念化的）是否在心理治疗方法之间存在差异。认知行为疗法和人际疗法在心理治疗阶段的进展方面几乎没有差异。此外，结果表明，心理治疗阶段可能不代表离散的、顺序不变的过程。
