This paper reports on the infra-and interbattery scaling of three morale and depression batteries comprised of self-reported items: PGC, G-H, and Z U N G . 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 Z U N G and PGC batteries
