Using hierarchical linear models procedures (Bryk & Raudenbush, 1992), growth curve analyses were performed to examine the temporal course, rate of change over time, and determinants of therapist competence in short-term anxiety-provoking psychotherapy (STAPP) (Sifneos, 1992). Treatments were 20 sessions long, were manualized, and therapists were experienced clinicians receiving manual-guided supervision. Patients (N= 13) had mostly anxiety diagnoses. Results indicated that, on average, therapist competence ratings followed a flat-line course over time. Estimated mean rate of change was close to zero and varied very little across therapists. Also, therapists who, in an initial session, were more competent in performing STAPP also intervened more frequently in a helping and protecting manner. One possible implication of the findings is that one initial evaluation may be an unbiased estimator of a therapist's general level of competence across sessions.
使用分层线性模型程序（Bryk和Raudenbush，1992），进行了生长曲线分析，以检验短期激发焦虑心理治疗（STAPP）（Sifneos，1992）中治疗师能力的时间进程、随时间的变化率以及决定因素。治疗为期20节，采用手册化形式，治疗师是接受手册指导监督的经验丰富的临床医生。患者（N = 13）大多被诊断为焦虑症。结果表明，平均而言，治疗师能力评分随时间呈平线走势。估计的平均变化率接近零，且不同治疗师之间变化很小。此外，在初始疗程中更擅长实施STAPP的治疗师，也更频繁地以帮助和保护的方式进行干预。这些发现的一个可能含义是，一次初始评估可能是治疗师在整个疗程中总体能力水平的无偏估计。
