An integrated intervention programme for couples facing colorectal cancer: A randomized controlled trial

Abstract

AbstractBackgroundUnder the guidance of a preliminary Live with Love Conceptual Framework, a Caring for Couples Coping with Colorectal Cancer (4Cs: CRC) programme was designed specifically for colorectal cancer couples. The objectives of this study included examining the efficacy of the programme for couples adapting to colorectal cancer and comparing the effects of different intervention delivery modes (online, face‐to‐face and blended) on couple outcomes.MethodsA four‐arm randomized controlled trial was conducted among Chinese colorectal cancer couples. Couples were randomly assigned to an online intervention, a face‐to‐face intervention, a blended intervention or a control group. Self‐efficacy, dyadic coping, communication and dyadic outcomes (physical and mental health, negative and positive emotions and marital satisfaction) were evaluated at baseline and 6 weeks later. Analysis of variance (ANOVA) and repeated measures ANOVA were employed to assess between‐group differences and within‐group effects in the four groups, respectively.ResultsA total of 179 couples completed the 6‐week study and post‐study assessments. The intervention showed generally medium‐to‐large effects across multiple measured outcomes, including self‐efficacy, dyadic coping, communication, mental health, negative emotions and positive emotions for both patients and spouse caregivers. Additionally, interventions delivered through different modes produced equally significant effects on couple outcomes.ConclusionsThe integrated intervention programme is effective in improving cancer adaptation in colorectal cancer couples. Long‐term follow‐up and a mix of quantitative and qualitative assessments are crucial for further evaluation of the programme.Trial registrationRetroactive registration is under review.
