The present study investigated the longitudinal development of body size perception in relation to different personality traits. A sample of Swiss adults (N=2905, 47% men), randomly selected from the telephone book, completed a questionnaire on two consecutive years (2012, 2013). Body size perception was assessed with the Contour Drawing Rating Scale and personality traits were assessed with a short version of the Big Five Inventory. Longitudinal analysis of change indicated that men and women scoring higher on conscientiousness perceived themselves as thinner one year later. In contrast, women scoring higher on neuroticism perceived their body size as larger one year later. No significant effect was observed for men scoring higher on neuroticism. These results were independent of weight changes, body mass index, age, and education. Our findings suggest that personality traits contribute to body size perception among adults.
本研究调查了与不同人格特质相关的身体大小感知的纵向发展。一个来自电话簿的瑞士成年人样本（N=2905，47%为男性），在连续两年（2012 年、2013 年）完成了一份问卷。身体大小感知使用轮廓绘图评分量表进行评估，人格特质使用大五人格量表的简短版本进行评估。变化的纵向分析表明，责任心得分较高的男性和女性在一年后自我感知更瘦。相比之下，神经质得分较高的女性在一年后自我感知的体型更大。而神经质得分较高的男性则没有观察到显著的影响。这些结果与体重变化、身体质量指数、年龄和教育无关。我们的研究结果表明，人格特质对成年人的身体大小感知有一定影响。
