Short version: yes, with real evidence behind it, and with caveats that most articles on this topic leave out. Here is the honest review, trials and weaknesses included.
The label covers three different things. Assessment-based preparation: a structured inventory (PREPARE/ENRICH, FOCCUS) that each partner completes separately, then a facilitator walks you through where you agree and disagree. Skills-based education: a course, most famously PREP, that teaches communication and conflict skills to groups of couples. Traditional counseling: sessions with a therapist or clergy member, shaped by whatever the couple brings. The research evidence differs across the three, so "does it work" needs unpacking.
The meta-analysis. Carroll and Doherty's 2003 review of premarital prevention programs, the standard reference in this literature, found an average effect size around 0.80, which translates to the average program participant being better off afterward than roughly 79% of couples who did not participate, mainly on communication quality and relationship skills measured shortly after the program.
The randomized trial. The largest randomized study assigned 662 US Army couples to PREP-based education or a control condition. Among the notable results: couples who had moved in together before committing, historically a higher-divorce-risk group, showed an elevated two-year divorce rate in the control condition (14.6% versus 7.5% for those who cohabited after committing), and the program essentially erased that elevated risk (7.8% versus 7.4%).
The long follow-up. German trials of EPL, a PREP adaptation, followed couples for 11 years and reported markedly lower dissolution rates among participants (around 20-27.5%) than controls (around 52.6%). Small samples, but among the longest windows in the field.
The predictive inventories. The assessment side has its own evidence: published follow-up studies report that PREPARE and FOCCUS scores predicted which couples would be satisfied versus struggling around 80% of the time over multi-year windows. Assessment is not intervention, but it reliably surfaces the terrain.
Publication bias is real here. When researchers re-ran the meta-analytic math including unpublished studies, the average benefit on relationship satisfaction shrank substantially, and in some analyses was no longer significant. The published literature almost certainly overstates the average effect. The strongest defensible claim is that skills measurably improve and several rigorous trials show reduced dissolution, not that every program transforms every couple.
The mechanism is murkier than advertised. Programs teach communication skills on the theory that better communication causes better marriages. Later research complicated this: changes in observed communication do not cleanly explain who ends up satisfied. The programs help; exactly why is still being worked out. Structured attention to the relationship, earlier, may matter as much as any specific technique.
Selection matters. Couples who sign up are already the deliberate ones. Randomized trials handle this, but the glowing testimonial you heard from a friend does not.
Typical routes, roughly ordered by cost:
Set against the average cost of a wedding, every option on this list rounds to zero.
Premarital preparation is one of the rare corners of self-improvement where randomized trials, long follow-ups, and validated instruments actually exist. The average published effect is inflated by publication bias, and anyone promising certainty is overselling. But the direction of the evidence is consistent: couples who examine the relationship deliberately, before the commitment locks, communicate better afterward, and in the strongest trials they dissolved less. The couples who benefit most are the ones who go early and answer honestly. That is a bar most couples can clear this month.
The Marriage Blueprint is a research-grounded assessment you take as a couple: questionnaires across eleven dimensions, six guided scenario conversations, then a couple profile, conflict portrait, and action plan. No account, no email; answers stay on your devices. Take the test together, or start solo with the 3-minute pattern quiz.
Most structured programs run 4 to 8 sessions or one intensive weekend. Inventory-based preparation is typically an hour of questionnaires plus two to four facilitated conversations.
The evidence case is strongest for exactly you: this is prevention, not repair. The couples in the trials were ordinary engaged couples, not distressed ones.
Whichever you will actually complete honestly. The skill content overlaps heavily. The Catholic tradition arguably invented structured marriage preparation, a history we tell in The Church got there first.
