Cancer Clinical Trial - A Self-efficacy Based Dietary Intervention

Status Terminated

Clinical Trial Summary

To develop and test the effectiveness of a dietary intervention aiming to enhance self-efficacy through sending images through instant messaging.

Clinical Trial Description

Healthy eating is linked to improved survival and quality of life among cancer survivors. However, previous studies showed that most cancer survivors were not adhering to dietary recommendations despite having made changes post-diagnosis. Conventional nutrition counseling interventions are often used in this population. However, they are labor and cost intensive and involved multiple sessions with participants. Written materials have often been used to facilitate improvements of dietary quality beyond nutrition counseling sessions but are outdated. Therefore, we propose to develop and test the effectiveness of a dietary intervention aiming to enhance self-efficacy through sending images through instant messaging. Methods to increase self-efficacy include performance accomplishment, persuasion, modelling and peer-modelling. A prospective, randomized controlled trial design will be used to test the effectiveness of the intervention. A total of 168 adult Chinese cancer survivors, diagnosed with non-metastatic cancer (Stages 0-III), and have completed all active treatments, including surgery and adjuvant treatments such as chemotherapy and radiation therapy will be recruited. Participants will be randomly assigned into one of two groups at a 1:1 ratio, using computer-generated block randomization sequences. The first group will be an active control group. Participants in this group will receive knowledge-based dietary information through an instant messaging applications biweekly for 6 times. The second group will be the intervention group. Participants will receive biweekly self-efficacy enhancing materials for 6 times. Materials will provide information about behavior-health link, provide information on consequences, provide instruction, and provide opportunities for social comparison. For example, the materials will provide recipe ideas and meal planning samples from fellow cancer survivors. All materials will be developed by a registered dietitian and will be consistent with published dietary guidelines for cancer survivors. Participants will have follow-up appointments at 3 months. Their dietary quality and skin carotenoid status will be monitored. It is hypothesized that dietary quality will be better and skin carotenoid status will be higher for participants in the intervention group compared to participants in the active control group. ;
