Telephone-based reminiscence therapy for colorectal cancer patients undergoing postoperative chemotherapy complicated with depression: a three-arm randomised controlled trial.

BACKGROUND: Colorectal cancer patients undergoing postoperative chemotherapy often exhibit symptoms of depression that in turn may negatively affect outcome. The aim of this study was to assess the efficacy of telephone-based reminiscence therapy on the depression, anxiety, subjective well-being, and social support of colorectal cancer patients undergoing postoperative chemotherapy complicated with depression.

METHODS: Patients were divided randomly into a control group (CON, n = 45), telephone support group (TS, n = 45), and telephone-based reminiscence therapy group (TBR, n = 45). Patients in TS and TBR groups received six 20-40-min telephone intervention sessions conducted weekly. Patients were assessed at baseline and at 6 weeks. The primary outcomes were changes on the Self-Rating Depression Scale (SDS) and Hamilton Depression Scale (HAMD), which were used to evaluate depression symptoms. Secondary outcomes were changes in Self-Rating Anxiety Scale (SAS), Hamilton Anxiety Scale (HAMA), Memorial University of Newfoundland Scale of Happiness (MUNSH), and Perceived Social Support Scale (PSSS) scores, which were used to evaluate anxiety symptoms, subjective well-being, and social support, respectively.

RESULTS: After 6 weeks, SDS and HAMD scores were significantly lower than pre-intervention baseline in the TBR group but not in the CON and TS groups (P < 0.05). Both SAS and HAMA scores were significantly reduced in TBR and TS groups but not the CON group (P < 0.05) following intervention; however, there was no significant difference in post-intervention scores between TS and TBR groups (P > 0.05). Neither telephone support nor telephone-based reminiscence therapy improved subjective well-being or social support (P > 0.05).

CONCLUSIONS: These findings suggest that telephone-based reminiscence therapy can reduce depression symptoms in colorectal cancer patients undergoing postoperative chemotherapy. Telephone-based reminiscence therapy may also improve anxiety, but no better than telephone support. Alternatively, telephone-based reminiscence therapy did not improve subjective well-being or social support. We suggest that clinicians provide appropriate telephone-based reminiscence therapy in long-term care institutions based on patient mental health status.
