Little is known about the role that personality and emotional readiness factors may play in participation and outcomes of premarital education programs in varying formats. Data collected via the RELATionship Evaluation Questionnaire (RELATE: Busby et al., 2001) was used to analyze how personality and emotional readiness factors affect perceived change and helpfulness in self-directed and workshop formats of premarital education for 384 individuals who participated in such interventions. Depression was significantly and negatively related to participant perception of positive change and helpfulness in a workshop setting. Kindness was positively and significantly related to perceived positive change in both workshop and self-directed formats, and income was negatively and significantly related to perceived positive change in workshop settings. Anxiety was significantly and positively related to perceived helpfulness in workshop settings. Implications of these findings are discussed. More research is needed to compare these results to other formats of premarital interventions, such as classes and counseling formats, and to more diverse population samples.
