该研究的目的是确定未密封的（参与者记录每日步数）与密封的计步器监测是否会引起成年人的反应（即由于意识到被监测而改变行为）。在一项随机对照交叉研究中，28 名健康白人成年人（12 名男性，M 年龄 = 51 +/- 9.9 岁；16 名女性，M 年龄 = 44 +/- 6.5 岁）完成了 2 种评估类型（密封与非密封计步器）。一半的参与者佩戴密封计步器 1 周，并将其提交给研究人员阅读。经过 2 周的清洗后，参与者佩戴未密封的计步器，记录 1 周内每天的总步数。其余参与者以相反的顺序完成协议。分析包括重复测量方差分析 (ANOVA)，使用条件（密封与未密封的每日平均步数）作为重复变量，使用性别和评估类型顺序作为间变量。密封与非密封计步器之间每天的步数没有显着差异，F(1, 24) = 0.51，p =.48，无论性别如何，F(1, 24) = 0.13，p =.72，或评估类型的顺序，F(1, 24) =.48，p =.50。密封与非密封评估的每日平均步数之间的组内相关系数 (ICC) 为 84，p
The study purpose was to determine whether unsealed (with participant recording of daily steps) versus sealed pedometer monitoring elicits reactivity (i.e., changed behavior due to awareness of being monitored) in adults. In a randomized controlled crossover study, 28 healthy White adults (12 men, M age = 51 +/- 9.9 years; and 16 women, M age = 44 +/- 6.5 years) completed 2 assessment types (sealed versus unsealed pedometer). Half of the participants wore a sealed pedometer for 1 week, submitting it for reading by research staff. After a 2-week washout, the participants wore an unsealed pedometer, recording total daily steps for 1 week. The remaining participants completed the protocol in reverse order. Analyses included a repeated measures analysis of variance (ANOVA) using condition (mean steps per day for sealed versus unsealed) as the repeated variable and gender and order of assessment type as the between variables. There was no significant difference between sealed versus unsealed pedometers in steps per day, F(1, 24) = 0.51, p =.48, regardless of gender, F(1, 24) = 0.13, p =.72, or order of assessment type, F(1, 24) =.48, p =.50. The intraclass correlation coefficient (ICC) between average steps per day for the sealed versus unsealed assessment was.84, p
