Impulsivity and extraversion have demonstrated associations with risky sexual behavior (RSB) and potentially traumatic events (PTEs). In addition, interpersonal trauma appears to be associated with RSB, but research on the relationship between RSB and noninterpersonal PTEs (e.g., accidental) is lacking. The current study aims to investigate the relationships between personality (i.e., impulsivity, extraversion), RSB and multiple types of PTEs (i.e., accidental, physical, or sexual).
Personality and demographic characteristics were assessed during participants' (N = 970) first semester of college, past-12 month PTEs and RSB were assessed during the second semester of participants' junior year. Multiple linear regression was used to examine the relationship between PTEs, personality factors, and RSB. Analyses were also conducted to examine the potential mediating effect of interpersonal PTEs on the relationship between personality and RSB.
Impulsivity and extraversion were significantly positively associated with RSB. Both physical and sexual PTEs, but not accidental PTEs, were also significantly positively associated with RSB. Sexual PTEs significantly mediated the relationship between impulsivity and RSB.
This is the first study to date to simultaneously examine the relationship between personality, RSB, and types of PTEs in a large sample of young adults. Exposure to interpersonal trauma appears to be a salient factor in the relationship between personality, specifically impulsivity, and RSB. These results indicate that college students may benefit from education regarding the potential negative outcomes of RSB, and that individuals with a history of interpersonal PTEs may be at increased risk for sexual risk taking.

冲动性和外向性已被证明与危险的性行为(RSB)和潜在创伤性事件(PTEs)有关。此外,人际创伤似乎与RSB有关,但关于RSB与非人际PTEs(如意外事件)之间关系的研究尚缺。本研究旨在调查人格(即冲动性、外向性)、RSB与多种类型的PTEs(即意外、身体或性方面的)之间的关系。
在参与者(N = 970)大学第一学期评估其人格和人口统计学特征,在参与者大三第二学期评估过去12个月的PTEs和RSB。使用多元线性回归来检验PTEs、人格因素和RSB之间的关系。还进行了分析以检验人际PTEs对人格与RSB之间关系的潜在中介作用。
冲动性和外向性与RSB显著正相关。身体和性方面的PTEs与RSB也显著正相关,但意外PTEs并非如此。性方面的PTEs显著介导了冲动性与RSB之间的关系。
这是迄今为止第一项在大量年轻成年人样本中同时研究人格、RSB和PTEs类型之间关系的研究。接触人际创伤似乎是人格(特别是冲动性)与RSB之间关系中的一个显著因素。这些结果表明,大学生可能会从关于RSB潜在负面结果的教育中受益,并且有人际PTEs病史的个体进行性冒险行为的风险可能会增加。(PsycINFO数据库记录
