Background: Despite significant psychosocial-spiritual needs adversely affecting the health-related quality of life (HRQoL) of adults living with cancer and their family caregivers in sub-Saharan Africa, there is a dearth of culturally tailored interventions to address these needs. This study evaluates the feasibility of a socio-spiritual intervention designed for adults with cancer and their family caregivers in sub-Saharan Africa, and preliminarily examines its impact on family/social support, spiritual needs, information needs, health literacy and HRQoL.

Methods: This study employed a single-site randomised controlled trial design. Eighty-eight dyads were randomly assigned to either a socio-spiritual intervention (n = 44 dyads) or usual care (n = 44 dyads). The intervention group participated in a 4-week face-to-face training programme with usual care, whereas the control group received only usual care over the same period.

Result: A total of 82 dyads completed the study (40 dyads in the intervention group and 42 dyads in the control group). The eligibility and acceptance rates were >85%, retention was >90% and treatment fidelity was high (between 88.5% and 94.6%). In terms of intervention effects, the intervention was helpful in reducing needs and improving HRQoL of adults with cancer (F (13, 65) = 24.50, p < 0.001; Wilks' Lambda = 0.17) and their family caregivers (F (13, 65) = 14.27, p < 0.001; Wilks' Lambda = 0.26).

Conclusion: This pilot study established the feasibility of a face-to-face training programme for adults with cancer and their families, as well as its potential for improving HRQoL of this population.

This study's findings imply that by supporting individuals with cancer and their family caregivers as a unit of care, both individual needs and components of HRQoL can be maintained or even improved. In current practice in Nigeria, only patients' needs are routinely addressed; caregivers often are left on their own to obtain information and support to deliver complex care in the home.
