Participants who receive continued coach contact following behavioral weight loss treatment are more successful in maintaining their weight loss long-term. The current study examines whether these contacts have dynamic effects, such that participants are most adherent to the prescribed weight loss behaviors in the days after the call, when motivation and goal salience may be heightened, than they are as time goes on. The current study examined the trajectory of calorie intake, physical activity, weight, and self-monitoring behavior in the fourteen days after a monthly coaching call among participants completing the maintenance phase of a behavioral weight loss trial. For physical activity outcomes, caloric intake, and weight, there were no changes across time. Participants did have the highest adherence and quality of dietary self-monitoring immediately after the call, which diminished over time. Coach contact may continually renew commitment to this burdensome but critical behavior. Likelihood of self-weighing showed an opposite trend, where participants were more likely to weigh themselves in the days more distal from the coach call. Results can inform the timing and content of future coach contact to promote weight control.
参与者在行为减肥治疗后继续接受教练的联系，长期保持减肥效果更为成功。本研究探讨了这些联系是否具有动态效应，例如，在通话后的几天内，当动机和目标凸显时，参与者最遵守规定的减肥行为，而随着时间的推移，他们的遵守程度可能会降低。本研究检查了在完成行为减肥试验维持阶段的参与者每月接受教练电话后的十四天内，卡路里摄入量、身体活动、体重和自我监测行为的轨迹。对于身体活动结果、卡路里摄入量和体重，没有随时间变化。参与者在通话后立即有最高的饮食自我监测的依从性和质量，但随着时间的推移逐渐降低。教练联系可能会持续更新对这种繁琐但关键行为的承诺。自我称重的可能性显示出相反的趋势，即参与者在距离教练电话更远的日子里更有可能称重。研究结果可以为未来促进体重控制的教练联系的时间和内容提供信息。
