This study examined cognitive disorders in 106 nursing home residents:
cognitively impaired (31), depressed (19), cognitive impaired and dep
ressed (34), and controls (22). Dependent measures were health, recall
, and the metamemory components of capacity, change, locus, and strate
gy. The mixed group's recall score was lower than that of the depresse
d group. The cognitively impaired group's recall score was lower than
both the control and depressed group. The capacity and change subscale
s differentiated between the cognitively impaired and the mixed group,
with the mixed group indicating unstable memory capacity (lessening)
and memory change (worsening). The control group's health scores were
greater than either the cognitively impaired group or the depressed gr
oup; the mixed group's health scores were significantly higher than th
e depressed group's scores.
