The current study examined the interactive influence of multiple factors (i.e., physical abuse severity and negative affectivity) in predicting youth's inpatient psychiatric length of stay (LOS), extending previous research focused on identification of only single LOS predictors. Elevated physical abuse severity was hypothesized to predict longer youth LOS, and negative affectivity was anticipated to exacerbate this relationship. This study included 42 youth. Clinicians rated youth temperament, whereas physical abuse severity and LOS were coded from youth medical records. Controlling for other previously determined predictors of LOS (i.e., age, gender, and GAF), moderation analyses confirmed hypotheses, revealing a temperament by environment interaction. Specifically, physical abuse severity was positively associated with LOS only in the context of high negative affectivity. Findings highlighted the importance of disentangling the interactive effects of multiple factors in predicting LOS. Moreover, critical clinical implications involving prioritized trauma assessment and treatment for inpatient youth are discussed.
本研究考察了多种因素（即身体虐待严重程度和消极情感性）在预测青少年住院精神科住院时长（LOS）方面的交互影响，拓展了以往仅关注单一住院时长预测因素识别的研究。研究假设身体虐待严重程度升高会预测青少年更长的住院时长，并且消极情感性会加剧这种关系。本研究纳入了42名青少年。临床医生对青少年的气质进行了评分，而身体虐待严重程度和住院时长则根据青少年的病历进行编码。在控制了其他先前确定的住院时长预测因素（即年龄、性别和总体功能评定量表得分）后，调节分析证实了假设，揭示了气质与环境的交互作用。具体而言，只有在消极情感性较高的情况下，身体虐待严重程度才与住院时长呈正相关。研究结果强调了在预测住院时长时理清多种因素交互作用的重要性。此外，还讨论了涉及对住院青少年进行优先创伤评估和治疗的关键临床意义。
