The purpose of this study was to examine differences in discharge outcomes between latent classes of youth in psychiatric residential treatment. The mediating effect of family therapy, behavioral management incidents, and length of stay on class membership and treatment outcomes were examined. The sample included 447 youth assigned to one of four classes. Guided by Thornberry and Krohn’s (2005) interactional theory of continuity and change, change in functional impairment was predicted based on the composition of risk versus protective factors that comprised the latent classes. A manual 3-step approach was used to fit a latent class mixture model and estimate conditional effects on impairment at discharge. A mediation model was used to examine indirect effects of treatment factors on outcomes between latent classes. The results showed that classes with lower-level risk factors and more protective factors experienced significantly greater reductions in impairment on average. Treatment outcomes were mediated by behavioral management incidents but not length of stay or the number family therapy sessions. The results demonstrate the usefulness of person-centered approaches for conducting subgroup analyses in residential care outcomes studies; highlighting differences in outcomes between groups and treatment factors that may mediate these differences.

本研究的目的是检查精神病院住院治疗的潜在青少年类别之间出院结果的差异。研究了家庭治疗、行为管理事件和停留时间对班级成员资格和治疗结果的中介作用。样本包括分配到四个班级之一的 447 名青年。在 Thornberry 和 Krohn (2005) 的连续性和变化交互理论的指导下，功能障碍的变化是根据构成潜在类别的风险与保护因素的构成来预测的。使用手动三步法来拟合潜在类别混合模型并估计对放电损伤的条件影响。调解模型用于检查治疗因素对潜在类别之间结果的间接影响。结果表明，具有较低水平风险因素和更多保护因素的班级的平均损伤减少幅度更大。治疗结果由行为管理事件决定，但与住院时间或家庭治疗次数无关。结果证明了以人为本的方法在住院护理结果研究中进行亚组分析的有用性；强调各组之间结果的差异以及可能介导这些差异的治疗因素。结果证明了以人为本的方法在住院护理结果研究中进行亚组分析的有用性；强调各组之间结果的差异以及可能介导这些差异的治疗因素。结果证明了以人为本的方法在住院护理结果研究中进行亚组分析的有用性；强调各组之间结果的差异以及可能介导这些差异的治疗因素。
