口服避孕药(OC)的使用是一种有价值但未被充分利用的自然实验,用于研究外源性激素对认知和行为方面的影响,特别是表现出性别或性别差异的方面。然而,有机碳的使用并不是随机分配的;由于与性别相关的原因,使用OCs的妇女可能与不使用OCs的妇女存在系统性差异,这可能会混淆OCs药代动力学效应的研究。因此,本研究的主要目的是调查社交媒体使用者和非用户在性别自我概念上是否存在差异,因为社会文化因素可能会影响使用社交媒体的人及其原因。第二个目的是检查不同药片配方的口服避孕药使用者在性别自我概念上是否存在差异。对395名年轻成年女性的多变量协方差分析(控制年龄)显示,在性别自我概念(表达性、工具性、女性化和男性化)四个方面,使用酒精饮料的女性(n=247)与不使用酒精饮料的女性(n=148)之间无显著差异,单变量效应值平均为d= 0.07。此外,当考虑到社会文化因素(即口服避孕药的使用原因)或药片的药代动力学特性(即雄激素性)时,关于群体差异的推断并没有改变。因此,研究结果表明,性别自我概念的差异并不是使用和不使用OC的基础,不同OC配方的雄激素性并不影响性别自我概念。综上所述,研究结果还强调了外源性卵巢激素影响的特异性,因为有文献记载对认知有影响,但对个人特征(如性别自我概念)没有影响。
Oral contraceptive (OC) use is a valuable and underutilized natural experiment for examining exogenous hormone effects on aspects of cognition and behavior, especially aspects that show sex or gender differences. OC use, however, is not randomly assigned; women who use OCs may systematically differ from non-users for gender-linked reasons that potentially confound investigations of the pharmacokinetic effects of OCs. Thus, the primary aim of this study was to investigate whether OC users and non-users differ in gender self-concepts, as sociocultural factors might influence who uses OCs and why. A secondary aim was to examine whether OC users of different pill formulations differ in gender self-concept. Multivariate analyses of covariance (controlling for age) on a large sample of 395 young adult women revealed no significant differences between OC users (n=247) and non-users (n=148) in four aspects of gender self-concept (expressivity, instrumentality, femininity, and masculinity), with univariate effect sizes averaging d=.07. Moreover, inferences about group differences did not change when considering sociocultural factors (i.e., reason for OC use) or pharmacokinetic properties of the pills (i.e., androgenicity). Thus, findings indicate that differences in gender self-concept do not underlie OC use and non-use, and that the androgenicity of different OC formulations does not impact gender self-concept. Taken together, findings also highlight the specificity of exogenous ovarian hormone influences, as there are documented effects on cognition but not on personal characteristics, such as gender self-concept.
