Opposite-Sex Siblings and Marital Beliefs Among Emerging Adults

Data from 428 emerging adults were analyzed to investigate how growing up with at least one opposite-sex sibling related to marital beliefs. Participants were divided into three groups: having an opposite-sex sibling, having only a same-same sibling(s), and having no siblings. Using the belief dimensions and assumptions of Marital Paradigms Theory, results from a MANCOVA indicated a few statistically significant associations regarding opposite-sex siblings. Those with an opposite-sex sibling tended to believe in having shorter ideal engagement periods (marital timing), rated getting married as especially important (marital salience), and were less likely to believe cohabitation was a good preparation for marriage (marital context). Implications for future research are briefly explored.
