Past research has shown how personality characteristics and demographics influence the likelihood of couples and individuals participating in marital interventions. However, these studies do not focus on the factors that influence men’s participation and are limited to their respective sample frames, making them difficult to generalize to a population. A nationally representative, population-level study of newlywed males may help to provide more generalizable insights regarding the factors that influence men’s participation in marital interventions. The current study had two purposes. First, this study sought to examine the personality and demographic factors that influenced the likelihood of men participating in a variety of marital interventions. Second, this study attempted to provide a demographic description of men who participated in marital interventions. A sample of 2,150 men were drawn from a nationally representative random probability sample known as the CREATE survey. Binary and multinomial logistic regression analyses were used to address the research questions. A total of three factors were found to be influential in the likelihood of men participating in marital interventions – religiosity, depressive symptoms, race/ethnicity. This study provides an in-depth view as to how men’s religiosity largely influenced the likelihood of them participating in marital interventions, nationwide. Such conclusions have valuable potential to help practitioners understand, in detail, how men’s religiosity may influence men to participate in marital interventions.
