As evidence of the benefits of marriage preparation continues to mount, so does the importance of investigating the characteristics of the interventions that are most helpful and for whom. In a sample of 1,409 individuals, this study compares perceived helpfulness of four marriage preparation interventions: class, community/church sponsored workshop, counseling, and self-directed. All interventions were perceived as helpful, but class and self-directed learning were rated more highly than counseling and workshops, independent of gender. Class and self-directed learning participants had the highest improvement scores overall, with women reporting greater positive change than men. Implications for marriage preparation interventions are discussed.
