人格被认为是健康行为的远端决定因素，并已被发现与年轻人的健康行为有关。然而，关于青少年人格与健康行为之间关系的研究却很缺乏。本研究探讨了荷兰两个青少年样本中大五人格维度与水果和蔬菜消费和体育活动（PA）之间的直接关联[样本1：n = 504;平均年龄= 14.5岁（SD = 1.7）;响应率20%;样本2：n = 476;平均年龄= 14.9（SD = 2.0）;响应率17%]。行为结果和个性进行了评估，有效的自我管理问卷。二元相关和多元回归分析进行，科恩的效果大小被用来解释协会发现。易接受性与蔬菜消费量呈正相关，而开放的经验与水果消费量和蔬菜消费量呈正相关。外向性与运动相关PA呈正相关。人格维度的标准化回归系数在0.09到0.13之间，解释了3 - 6%的行为变异，表明效应大小很小。我们的研究结果表明，人格维度与水果和蔬菜的消费和运动相关的PA在青少年。未来的研究应探讨人格与青少年健康行为之间可能的中介。
Personality is regarded as a distal determinant of health behavior and has been found to be associated with health behavior in young adults. Research investigating the association between personality and health behaviors in adolescents, however, is lacking. The present study explored the direct associations between Big Five personality dimensions with fruit and vegetable consumption and physical activity (PA) in two Dutch adolescent samples [Sample 1: n = 504; mean age = 14.5 years (SD = 1.7); response rate 20%; Sample 2: n = 476; mean age = 14.9 (SD = 2.0); response rate 17%]. Behavioral outcomes and personality were assessed with validated self-administered questionnaires. Bivariate correlations and multiple regression analyses were conducted, and Cohen's effect sizes were used to interpret the associations found. Agreeableness was positively associated with vegetable consumption, while Openness to Experience was positively associated with fruit consumption and vegetable consumption. Extraversion was positively associated with sports-related PA. Standardized regression coefficients for personality dimensions ranged from 0.09 to 0.13, explaining 3-6% of variance in behavior, indicating small effect sizes. Our results suggest that personality dimensions are associated with fruit and vegetable consumption and sports-related PA in adolescents. Future research should explore possible mediators between personality and health behavior in adolescents.
