Mm. Friedman et Ja. Griffin, Relationship of physical symptoms and physical functioning to depression in patients with heart failure, HEART LUNG, 30(2), 2001, pp. 98-104
OBJECTIVE: The purpose of this study was to determine the relative contribu
tion of physical symptoms and physical functioning to depression in adult p
atients with heart failure during hospitalization and the early postdischar
ge period.
DESIGN: An exploratory, correlational longitudinal design was used.
PATIENTS: The sample included 170 subjects with heart failure.
RESULTS: Subjects' mean scores on the depression scale indicated that subje
cts were not depressed on average; however, 30% of the sample (n = 52) had
scores indicative of clinical depression. Both physical symptoms (r = 0.48)
and physical functioning (r = -0.32) were moderately correlated with depre
ssion Physical symptoms contributed 13% uniquely to the variance in depress
ion while physical functioning contributed only 2% uniquely to the variance
in depression. Multiple regression analyses indicated that physical sympto
matology is more closely related to depression than is physical functioning
in adults with heart failure.
CONCLUSIONS: This study showed the patients with heart failure who had incr
eased physical symptoms and poorer physical functioning reported increased
symptoms of depression. Physical symptoms explained a greater portion of th
e variance in depression than did physical functioning. Thus, it appears th
at patients with heart failure are affected emotionally by both their physi
cal symptoms and their limitations in their physical functioning, but depre
ssion is more strongly related to having more physical symptoms than having
greater limitations in physical functioning.
