BACKGROUND
This follow-up study investigated the year-round effects of a four-week randomized controlled trial using different types of feedback on employees' physical activity, including a need-supportive coach intervention.
METHODS
Participants (n = 227) were randomly assigned to a Minimal Intervention Group (MIG; no feedback), a Pedometer Group (PG; feedback on daily steps only), a Display Group (DG; feedback on daily steps, on daily moderate-to-vigorous physical activity [MVPA] and on total energy expenditure [EE]), or a Coaching Group (CoachG; same as DG with need supportive coaching). Daily physical activity level (PAL; Metabolic Equivalent of Task [MET]), number of daily steps, daily minutes of moderate to vigorous physical activity (MVPA), active daily EE (EE > 3 METs) and total daily EE were measured at five time points: before the start of the 4-week intervention, one week after the intervention, and 3, 6, and 12 months after the intervention.
RESULTS
For minutes of MVPA, MIG showed higher mean change scores compared with the DG. For steps and daily minutes of MVPA, significantly lower mean change scores emerged for MIG compared with the PG. Participants of the CoachG showed significantly higher change scores in PAL, steps, minutes of MVPA, active EE, total EE compared with the MIG. As hypothesized, participants of the CoachG had significantly higher mean change scores in PAL and total EE compared with groups that only received feedback. However, no significant differences were found for steps, minutes of MVPA and active EE between CoachG and PG.
CONCLUSIONS
Receiving additional need-supportive coaching resulted in a higher PAL and active EE compared with measurement (display) feedback only. These findings suggest to combine feedback on physical activity with personal coaching in order to facilitate long-term behavioral change. When it comes to increasing steps, minutes of MVPA or active EE, a pedometer constitutes a sufficient tool.

背景
本随访研究调查了一项为期四周的随机对照试验的全年效果，该试验使用了不同类型的反馈来监测员工的身体活动情况，包括提供支持性的教练干预。
方法
参与者（n=227）被随机分配到最小干预组（MIG；无反馈）、计步器组（PG；仅反馈每日步数）、显示组（DG；反馈每日步数、每日中等到剧烈体力活动[MVPA]和总能量消耗[EE]）或教练组（CoachG；与需要支持的教练相同，DG）。在五个时间点测量每日体力活动水平（PAL；任务代谢当量[MET]）、每日步数、每日中等到剧烈体力活动（MVPA）分钟数、活跃的每日 EE（EE>3 METs）和总每日 EE：在干预前四周开始前、干预后一周、干预后 3、6 和 12 个月。
结果
对于 MVPA 分钟数，MIG 组的平均变化评分高于 DG 组。对于步数和每日 MVPA 分钟数，MIG 组的平均变化评分明显低于 PG 组。与 MIG 相比，CoachG 组的参与者在 PAL、步数、MVPA 分钟数、活跃 EE 和总 EE 方面的变化评分明显更高。与仅接受反馈的组相比，如假设所料，CoachG 组的参与者在 PAL 和总 EE 方面的平均变化评分明显更高。然而，在 CoachG 组和 PG 组之间，在步数、MVPA 分钟数和活跃 EE 方面没有发现显著差异。
结论
与仅接受测量（显示）反馈相比，接受额外的支持性教练指导会导致更高的 PAL 和活跃 EE。这些发现表明，为了促进长期行为改变，应将体力活动反馈与个人教练相结合。当涉及到增加步数、MVPA 分钟数或活跃 EE 时，计步器是一种足够的工具。
