Mutual communication intervention for colorectal cancer patient–spousal caregiver dyads: A randomized controlled trial

Objective

Gender could impact the psychosocial outcomes and coping strategies of cancer patients and their spousal caregivers (SCs). This study aims to develop a gender-concerned program for colorectal cancer (CRC) couple-based mutual communication intervention (MCI) and to assess its effectiveness on the intra-couple relationship and the individual functions of the partners.

Design

A randomized clinical trial with two study groups was utilized.

Methods

A total of 144 CRC patients and their SCs were randomly assigned to either MCI or usual care (UC) groups, and all of them were required to complete the measurements at baseline and post-intervention. The primary outcome was for mutual communication, and the secondary outcomes included dyadic coping, relationship satisfaction, anxiety, depression, benefit finding and quality of life. The data were analysed by multi-level modelling.

Results

The MCI program was feasible and acceptable for Chinese CRC couples and was effective for the improvement of the intra-couple relationship and the individual functions of each partner. CRC patients showed more improvement in mutual communication and dyadic coping than their SCs in the MCI group. Also, this intervention effectiveness was found to be independent of gender.

Conclusions

The MCI program is beneficial for Chinese CRC couple's adaptation outcomes. This suggests that clinical medical staff should consider the gender tendency during the implementation of interventions. More researches are needed to extend the application of the MCI program to different participants (e.g. patients with the diagnosis of other types of cancer and their SCs).
