The purpose of the study was to identify variables that predicted three different dispositions of patients seen in a psychiatric emergency room: hospitalization, an emergency housing program, and an outpatient crisis program.
Social, psychiatric, demographic, and vocational characteristics of 50 patients in each disposition group were examined to learn whether they varied sufficiently to explain the different dispositions.
Patients in the hospitalized group were most psychologically impaired and those in the crisis program group least impaired. Patients referred to emergency housing were more moderately impaired but not always significantly different in impairment from hospitalized patients. Discriminant analysis yielded a model of 11 variables whose combined effect accounted for 79 percent of the variance. Psychiatric determinants were the most important predictors, although social, vocational, and demographic variables were also significant. Using these predictors, 76 percent of the original sample and 63 percent of a cross-validation sample were correctly classified by disposition group.
The results confirmed the importance of psychiatric determinants in the dispositional process. The similarity between hospitalized patients and those assigned to emergency housing suggests that some hospitalized patients would be good candidates for alternative treatment.
本研究的目的是确定能够预测在精神科急诊室就诊的患者的三种不同处置方式的变量，这三种处置方式分别为住院治疗、紧急住房项目和门诊危机干预项目。
对每个处置方式组中的50名患者的社会、精神、人口统计学和职业特征进行检查，以了解它们是否存在足够差异来解释不同的处置方式。
住院组患者的心理损伤最为严重，危机干预项目组患者的损伤最轻。被转介到紧急住房项目的患者损伤程度中等，但与住院患者相比，损伤程度并不总是存在显著差异。判别分析得出了一个由11个变量组成的模型，其综合效应解释了79%的方差。精神科决定因素是最重要的预测指标，尽管社会、职业和人口统计学变量也具有显著性。使用这些预测指标，原始样本中的76%和交叉验证样本中的63%能够按处置方式组正确分类。
结果证实了精神科决定因素在处置过程中的重要性。住院患者与被分配到紧急住房项目的患者之间的相似性表明，一些住院患者可能是替代治疗的合适人选。
