Abstract

Testosterone (T) has been conceptualized as a biomarker of individual differences, yet T associations with the Big Five personality traits are inconsistent. Athletes provide a suitable model for evaluation here, as T co-expresses traits related to male-to-male competition and fitness with cortisol (C) playing a moderating role. This study investigated associations between the Big Five traits, T, and C in adolescent male athletes. One hundred and twenty male ice hockey players (aged 14-19 years) were assessed for blood total (T, C) and free (FT, FC) hormones, body-size dimensions (i.e., body mass, height, body mass index [BMI]), the Big Five personality traits (i.e., extraversion, neuroticism, agreeableness, conscientiousness, openness), and trait anxiety. Correlational and regression (with age and BMI as covariates) analyses identified a positive effect of FT on extraversion, but a negative FT effect on neuroticism and anxiety (p < 0.05). Significant FT × FC interactions emerged for extraversion and agreeableness. Slope testing revealed that FT had a positive effect on extraversion at the FC mean and +1 SD, and a negative effect on agreeableness with FC at +1 SD. In conclusion, adolescent male athletes with a higher serum FT concentration tended to express higher extraversion, but lower neuroticism and anxiety. The FT association with extraversion was moderated by FC concentration, as was agreeableness. Therefore, high-FT athletes presented a behavioural disposition that favours dominance and resiliency, with some dependencies on FC availability. Since all association effect sizes were weak, replicate studies on larger adolescent samples are needed.

青少年男性运动员的五大人格特质、睾酮和皮质醇之间的关系。
睾酮(T)已被概念化为个体差异的生物标志物,但睾酮与五大人格特质之间的关联并不一致。在此,运动员提供了一个合适的评估模型,因为睾酮与皮质醇(C)共同表达与男女竞争和体能相关的特质,而皮质醇(C)起着调节作用。本研究调查了青少年男性运动员的五大特质、T 和 C 之间的关联。对 120 名男性冰上曲棍球运动员(14-19 岁)进行了血液总激素(T、C)和游离激素(FT、FC)、体型维度(即体重、身高、体重指数 [BMI])、五大人格特质(即外向性、神经质、宜人性、自觉性、开放性)和特质焦虑的评估。相关分析和回归分析(以年龄和体重指数作为协变量)发现,FT 对外向性有正向影响,但对神经质和焦虑有负向影响(P < 0.05)。外向性和宜人性出现了显著的 FT × FC 交互作用。斜率测试显示,FT 在 FC 平均值和 +1SD(+1 SD)时对外向性有正向影响,而在 FC +1SD(+1 SD)时对宜人性有负向影响。总之,血清中 FT 浓度较高的青少年男性运动员往往表现出较高的外向性,但神经质和焦虑程度较低。FT与外向性的关系受FC浓度的调节,而与合意性的关系也是如此。因此,高 FT 运动员的行为倾向倾向于支配性和应变性,但与 FC 的可用性有一定关系。由于所有关联的效应大小都较弱,因此需要在更大的青少年样本中进行重复研究。
