PROBLEM. Although researchers suggest treatments that provide patients with
an active coping strategy may increase patients' sense of self-efficacy, p
revious studies have not measured patients' self-efficacy.
METHODS. Eighteen women receiving chemotherapy for breast cancer were rando
mized to efficacy-enhancing experimental (n = 10) and usual-care control (n
= 8) groups. The experimental group received five interventions delivered
monthly. Variables-quality of life, symptom distress, and self-care self-ef
ficacy-were measured at baseline and at 4 and 8 months later.
FINDINGS. At 4 and 8 months the interaction effects for the Functional Asse
ssment of Cancer Treatment-Breast, used to measure quality of life, ranged
from small for functional concerns to large far social concerns. Interactio
n effects for symptom distress, measured by the Symptom Distress Scale, wer
e large. Interaction effects for self-care self-efficacy ranged from small
for Enjoying Life and Stress Reduction, medium for Stress Reduction, and la
rge for Making Decisions.
CONCLUSIONS. Interventions to promote self-efficacy may increase quality of
life and decrease distress for women diagnosed with breast cancer.
