 To blind the subject to the control or the intervention allocation, they will be told that the trial focuses on healthy lifestyles including weight, substance use, and exercise. The clinician and complementary health workers will not be told which of their patients are randomized in the control or intervention arm. This methodology ensures appropriate concealment and should prevent contamination. The participants in both the control and the intervention arms will be contacted for follow-up interviews at one, three and six months to assess outcomes. Sub-samples of both control and intervention subjects will be selected for participation in focus groups to seek input into their experience of using the new knowledge and skills in practice, and how it might be improved in the Kenyan context.
