Infidelity is a common phenomenon in marriages but is poorly understood. The current study examined variables related to extramarital sex using data from the 1991-1996 General Social Surveys. Predictor variables were entered into a logistic regression with presence of extramarital sex as the dependent variable. Results demonstrated that divorce, education, age when first married, and 2 "opportunity" variables--respondent's income and work status--significantly affected the likelihood of having engaged in infidelity. Also, there were 3 significant interactions related to infidelity: (a) between age and gender, (b) between marital satisfaction and religious behavior, and (c) between past divorce and educational level. Implications of these findings and directions for future research are discussed.
不忠是婚姻中的常见现象，但人们对此了解甚少。当前的研究使用1991年至1996年综合社会调查的数据，考察了与婚外性行为相关的变量。将预测变量纳入以是否有婚外性行为为因变量的逻辑回归分析。结果表明，离婚、受教育程度、初婚年龄以及两个“机会”变量（受访者的收入和工作状况）显著影响发生不忠行为的可能性。此外，有3个与不忠行为相关的显著交互作用：（a）年龄与性别之间的交互作用，（b）婚姻满意度与宗教行为之间的交互作用，以及（c）过去的离婚经历与教育水平之间的交互作用。本文讨论了这些研究结果的意义以及未来研究的方向。
