背景资料：社会比较反馈是经常使用的体力活动干预措施，但反馈的最佳设计是unknown. Methods：这4臂，随机试验包括一个13周的干预期和13周的随访期。在干预期间，4人团队参加每周抽奖，价值约为1.40美元/天，并视团队平均每天≥ 7000步而定。社会比较反馈的性能，每周提供了26周，不同的参考点（第50与第75百分位数）和宽恕使用的活动数据（所有7天或最好的5 7天）。主要结果是参与者达到7000步目标的平均比例。结果：在干预期间，未校正的参与者达到目标的平均比例为0.47（95%置信区间[CI]：0.38 - 0.56），第50百分位数组，0.38（95% CI：0.30 - 0.37）第75百分位数组，0.40（95% CI：0.31 - 0.49），宽恕组第50百分位数，（95%CI：0.38至0.55）在第75百分位与宽恕arm.In调整模型在干预和后续periods.Conclusions：改变社会比较反馈没有影响体力活动。
Background: Social comparison feedback is often used in physical activity interventions but the optimal design of feedback is unknown.Methods: This 4-arm, randomized trial consisted of a 13-week intervention period and 13-week follow-up period. During the intervention, 4-person teams were entered into a weekly lottery valued at about $1.40/day and contingent on the team averaging ≥7000 steps per day. Social comparison feedback on performance was delivered weekly for 26 weeks, and varied by reference point (50th vs 75th percentile) and forgiveness in use of activity data (all 7 d or best 5 of 7 d). The primary outcome was the mean proportion of participant-days achieving the 7000-step goal.Results: During the intervention period, the unadjusted mean proportion of participant-days that the goal was achieved was 0.47 (95% confidence interval [CI]: 0.38 to 0.56) in the 50th percentile arm, 0.38 (95% CI: 0.30 to 0.37) in the 75th percentile arm, 0.40 (95% CI: 0.31 to 0.49) in the 50th percentile with forgiveness arm, and 0.47 (95% CI: 0.38 to 0.55) in the 75th percentile with forgiveness arm. In adjusted models during the intervention and follow-up periods, there were no significant differences between arms.Conclusions: Changing social comparison feedback did not impact physical activity.
