This paper reports on the intra- and interbattery scaling of three morale and depression batteries comprised of self-reported items: PGC, G-H, and ZUNG. Responses to the three scales were sought from a sample of long-term residents of a state mental hospital. First, the batteries were factor analyzed separately to identify the intrabattery scales; then the resultant scales were compared using canonical correlation and super matrix factor analysis to identify the interbattery themes. These analyses resulted in the identification of a Clinical Depression domain across all three batteries and single independent themes in both the Zung and PGC batteries.
本文报告了由自我报告项目组成的三个士气与抑郁量表（PGC、G-H和ZUNG）在量表内部及量表之间的量表化情况。从一所州立精神病院的长期住院患者样本中获取了对这三个量表的回答。首先，分别对这些量表进行因素分析以确定量表内部的分量表；然后使用典型相关分析和超级矩阵因素分析对所得分量表进行比较，以确定量表之间的主题。这些分析确定了所有三个量表中都存在的临床抑郁领域，以及Zung量表和PGC量表中的单一独立主题。
