In an MRT, intervention components target proximal outcomes that are usually either a short-term version of a distal outcome (e.g., number of steps taken the current day when the distal outcome is the average daily steps over a longer period of time) or hypothesized mediators of the distal outcome (for someone attempting to quit smoking, a relaxation exercise to reduce the proximal outcome of stress over the next 2 hours will hopefully impact the distal outcome of time to relapse).
