This experiment evaluated the efficacy of television delivery of a behavioral weight reduction program. Seventy-one overweight adults were randomly assigned to a live-contact weight loss group that was videotaped for viewing by other groups, a live-contact group that was not videotaped, a television-delivered group that observed the videotaped weight loss sessions, or a waiting-list control group. Participants in all 3 treatment groups lost significantly more weight during the 8-week treatment program than those in the waiting-list control group. There was no significant weight loss differences among the 3 treatment groups during the program. These weight changes were maintained at 3-month follow-up. At 15-month follow-up, the television-delivered group and the live-contact group maintained their weight losses, whereas the videotaped group did not. Cost-effectiveness analyses indicated that the television-delivered group received the most cost-effective treatment.
本实验评估了通过电视播放行为减肥计划的效果。71名超重成年人被随机分为四组：一组是进行现场接触式减肥且录像以供其他组观看的减肥组，一组是进行现场接触式减肥但未录像的减肥组，一组是观看录像减肥课程的电视播放组，还有一组是候补对照组。在为期8周的治疗计划中，所有三个治疗组的参与者体重减轻幅度均显著大于候补对照组。在该计划期间，三个治疗组之间的体重减轻没有显著差异。这些体重变化在3个月的随访中得以维持。在15个月的随访中，电视播放组和现场接触组维持了体重减轻，而录像组则没有。成本效益分析表明，电视播放组接受的是最具成本效益的治疗。
