Effectiveness of a phone-based support program on self-care self-efficacy, psychological distress, and quality of life among women newly diagnosed with breast cancer: A randomized controlled trial.

ABSTRACT

PURPOSE: This study aimed to determine the effectiveness of a Phone-Based Support Program (PBSP) for newly diagnosed women with breast cancer. METHODS: A two-group repeated measures randomized controlled trial was designed. Participants included 94 patients aged 18-60 years who were newly diagnosed with breast cancer and undergoing chemotherapy in a tertiary hospital in China. They were randomly assigned to the intervention and the control groups. Participants in the intervention group were enrolled in a four-session PBSP, consisting of four interactive sections learning, discussion, ask-the-expert, and personal stories, plus the routine care. Outcomes included patients' self-care self-efficacy, psychological distress (including symptom distress, anxiety, and depression), and quality of life. These were assessed at three time points pre-intervention (T1), post-intervention (T2), and follow-up (T3) by using the self-care self-efficacy scale, the M.D. Anderson Symptom Inventory, the hospital anxiety and depression scale, and the global health status scale. RESULTS: After completion of the intervention, participants in the intervention group had significantly (p < .001) higher self-care self-efficacy (T2 Mdiff = 11.49, T3 Mdiff = 22.33), better quality of life (T2 Mdiff = 8.18, T3 Mdiff = 17.19), lower symptom distress (T2 Mdiff = -26.68, T3 Mdiff = -54.76), less anxiety (T2 Mdiff = -2.52, T3 Mdiff = -5.11), and less depression (T2 Mdiff = -3.61, T3 Mdiff = -6.71) than those in the control group. CONCLUSION: These findings indicate that the PBSP is effective. Healthcare professionals, especially nurses, could utilize it to enhance self-care self-efficacy and quality of life, as well as decrease psychological distress among women newly diagnosed breast cancer.
