Scales for assessing depression are well developed for non-psychotic populations but have been criticized for being inappropriate for psychotic populations. As a result we have developed a new rating scale for the measurement of depression in schizophrenia based on items selected from the Hamilton Depression Rating Scale and the Present State Examination. The selection was based on a three stage procedure first factor analysis then measures of internal consistency and finally face validity. Ratings of depression were made on 50 acutely ill schizophrenics meeting DSM-III criteria for schizophrenia assessed at two points in time. Our results indicate that several items from both scales form a superior instrument for measuring depression in schizophrenia. The eleven items generated a Cronbach's alpha of 0.84 at time one and 0.89 at time 2.
评估抑郁症的量表在非精神病患者群体中已得到充分发展，但因不适用于精神病患者群体而受到批评。因此，我们基于从汉密尔顿抑郁量表和现况检查中选取的项目，开发了一种新的评定量表，用于测量精神分裂症患者的抑郁情况。选择过程基于三个阶段：首先进行因素分析，然后测量内部一致性，最后进行表面效度评估。对50名符合DSM-III精神分裂症标准的急性精神分裂症患者在两个时间点进行抑郁评定。我们的结果表明，这两个量表中的几个项目构成了一种用于测量精神分裂症患者抑郁情况的更优工具。这11个项目在第一次测量时的克朗巴赫α系数为0.84，在第二次测量时为0.89。
