OBJECTIVE Most research on the dose-effect (DE) and good-enough level (GEL) models of change has used general outcome measures. The purpose of this study was to determine if predictions from these models generalize to specific presenting concerns and outcome measures. METHOD A large sample of treatment-seeking college students (N = 64,319) who attended different numbers of therapy sessions and completed the College Counseling Assessment of Psychological Symptoms-34 (CCAPS-34, Locke et al., Measurement & Evaluation in Counseling & Development, 2012, 45, p. 151) during sessions was used. An analysis of reliable and clinically significant improvement (RCSI) and latent growth curve models (LGCMs) were used for clients attending different numbers of sessions across eight scales from the CCAPS-34 to examine the: (a) amount of change from the first to last session, (b) rates of RCSI, (c) shape of change trajectories, and (d) rates of change across sessions. RESULTS Across all CCAPS-34 scales, clients who attended more sessions tended to experience more improvement, had higher rates of RCSI, and the trajectories of change were nonlinear, consistent with the DE model. Clients who attended fewer sessions tended to experience faster rates of change than those who attended more sessions, consistent with the GEL model. CONCLUSIONS Aspects of both the DE and GEL models appear to generalize to specific outcome measures on the CCAPS-34. Results suggest both individual differences in sensitivity to therapy and amount of therapy received influence therapeutic change. A greater focus on individual needs, especially early in treatment, may be especially important when determining the length of therapy. (PsycInfo Database Record (c) 2021 APA, all rights reserved).

针对特定心理问题的剂量效应和足够好的变化水平模型。

目标 大多数关于剂量效应 (DE) 和足够好水平 (GEL) 变化模型的研究都使用了一般结果测量。本研究的目的是确定这些模型的预测是否可以推广到特定的呈现问题和结果测量。方法 大量寻求治疗的大学生 (N = 64,319)，他们参加了不同数量的治疗课程并完成了心理症状的大学咨询评估 - 34 (CCAPS-34，Locke 等人，咨询与发展的测量与评估) , 2012, 45, p. 151) 在会议期间被使用。对可靠和临床显着改善 (RCSI) 和潜在生长曲线模型 (LGCM) 的分析用于客户参加 CCAPS-34 的八个量表中不同数量的会议，以检查：(a) 从第一个会话到最后一个会话的变化量，(b) RCSI 的速率，(c) 变化轨迹的形状，以及 (d) 会话之间的变化率。结果 在所有 CCAPS-34 量表中，参加更多会议的客户往往体验到更多的改善，具有更高的 RCSI 率，并且变化轨迹是非线性的，与 DE 模型一致。参加较少会议的客户往往比参加更多会议的客户经历更快的变化，这与 GEL 模型一致。结论 DE 和 GEL 模型的各个方面似乎都适用于 CCAPS-34 上的特定结果测量。结果表明，个体差异对治疗的敏感性和接受的治疗量都会影响治疗变化。更加关注个人需求，尤其是在治疗早期，在确定治疗时间时可能尤其重要。（PsycInfo 数据库记录 (c) 2021 APA，保留所有权利）。
