本调查的目的是检查社会期望和社会认可作为三项自我报告的身体活动评估的错误来源，使用身体活动的客观测量作为参考测量。 1997 年，居住在马萨诸塞州伍斯特市的女性 (n = 81) 完成了双标记水测量，并佩戴活动监测器 14 天。他们还完成了 7 次由访谈员管理的 24 小时身体活动回忆 (PARS) 和两次不同的自我管理的 7 天 PARS。人格特质“社会期望”和“社会认可”的测量回归到1）从双标记水和每个身体活动评估工具估计的身体活动能量消耗之间的差异，以及2）监测器得出的身体活动持续时间和每个工具之间的差异。社会期望与活动的过度报告相关，导致第二个 7 天 PAR 的体力活动能量消耗高估 0.65 kcal/kg/天（95% 置信区间：0.06、1.25），并且高估活动持续时间 4.15-11.30 分钟/天（均为 7 天 PARS）。社会认可与低估 24 小时 PAR 体力活动（-0.15 kcal/kg/天，95% 置信区间：-0.30，0.005）有微弱相关。在本研究中，体型与报告偏倚无关。作者得出的结论是，社会期望和社会认可可能会影响某些调查工具上自我报告的身体活动。
The purpose of this investigation was to examine social desirability and social approval as sources of error in three self-reported physical activity assessments using objective measures of physical activity as reference measures. In 1997, women (n = 81) living in Worcester, Massachusetts, completed doubly labeled water measurements and wore an activity monitor for 14 days. They also completed seven interviewer-administered 24-hour physical activity recalls (PARS) and two different self-administered 7-day PARS. Measures of the personality traits "social desirability" and "social approval" were regressed on 1) the difference between physical activity energy expenditure estimated from doubly labeled water and each physical activity assessment instrument and 2) the difference between monitor-derived physical activity duration and each instrument. Social desirability was associated with overreporting of activity, resulting in overestimation of physical activity energy expenditure by 0.65 kcal/kg/day on the second 7-day PAR (95% confidence interval: 0.06, 1.25) and overestimation of activity durations by 4.15-11.30 minutes/day (both 7-day PARS). Social approval was weakly associated with underestimation of physical activity on the 24-hour PAR (-0.15 kcal/kg/day, 95% confidence interval: -0.30, 0.005). Body size was not associated with reporting bias in this study. The authors conclude that social desirability and social approval may influence self-reported physical activity on some survey instruments.
