This study investigated the relation between social desirability and self-reported physical activity in web-based research.
A longitudinal study (N = 5,495, 54% women) was conducted on a representative sample of the Dutch population using the Marlowe-Crowne Scale as social desirability measure and the short form of the International Physical Activity Questionnaire. Social desirability was not associated with self-reported physical activity (in MET-minutes/week), nor with its sub-behaviors (i.e., walking, moderate-intensity activity, vigorous-intensity activity, and sedentary behavior). Socio-demographics (i.e., age, sex, income, and education) did not moderate the effect of social desirability on self-reported physical activity and its sub-behaviors.
This study does not throw doubt on the usefulness of the Internet as a medium to collect self-reports on physical activity.
本研究调查了网络研究中社会期望与自我报告体力活动之间的关系。
本研究采用 Marlowe-Crowne 量表作为社会期望度量,对荷兰代表性人群进行了一项纵向研究(N=5495,54%为女性),并使用国际体力活动问卷短表进行调查。社会期望与自我报告的体力活动(以代谢当量分钟/周为单位)以及体力活动的子行为(即步行、中等强度活动、高强度活动和久坐行为)均无关联。社会人口统计学因素(即年龄、性别、收入和教育)并不能调节社会期望对自我报告体力活动及其子行为的影响。
本研究并未对互联网作为收集体力活动自我报告的媒介的有效性提出质疑。
