Semantically similar decisions — same territory, different trade-offs.
Among couples who entered couple therapy in the most rigorous available randomised trial, 26-28% were separated or divorced at the 5-year follow-up, and only 48% showed sustained clinically significant improvement (Christensen et al., 2010, n=134 chronically distressed couples). Among US adults broadly, 66% have never attended or considered couple therapy (Grow Therapy/YouGov, December 2025, n=2,514), and among distressed couples who never seek treatment Lebow and Snyder’s (2022) review of the literature finds “little improvement in relationship satisfaction.” The bilateral comparison points consistently toward inaction dominating: couples who do not seek help rarely improve on their own, and the majority of relationship distress compounds over the 2.68 years (Doherty et al., 2021, n=270) the average help-seeking couple waits before entering therapy — let alone for the much larger group that never goes at all.
The action-side data require careful reading. The Christensen trial recruited seriously and chronically distressed couples who volunteered for a clinical research program — a help-motivated, high-distress sample unlikely to represent the full range of couples who attend therapy in everyday clinical practice. Of the 26-28% who divorced within 5 years, many had entered therapy precisely to manage an already-failing relationship; the Grow Therapy survey finding that 56% of divorced therapy-attenders described their attendance as “a final attempt to prevent a split” suggests purposeful rather than regret-laden attendance. At the same time, only 56% of couples who showed clinically significant improvement at end of treatment maintained that improvement at the 5-year mark (Baucom et al., 2015), confirming that gains are not durable for a substantial minority. The 29% action-side proxy should be read as an upper bound for regret, not a floor.
The inaction side is harder to measure directly because no large-scale survey asks people who never attended therapy whether they regret that decision. The 42% inaction proxy is anchored to the US population divorce rate as a conservative lower bound: roughly 39-42% of first marriages end in divorce, and Lebow and Snyder’s (2022) review confirms that distressed couples who receive no treatment rarely improve on their own, meaning actual deterioration or dissolution among relationship-distressed non-attenders is higher than the general population divorce figure. The 13-percentage-point inaction-dominance gap should not be read as a precise effect size; the uncertainty on the inaction side is wide and the true rate for distressed non-attenders is likely substantially higher than 42%. Both the action and inaction estimates share a common limitation: they reflect outcomes, not regret, and outcome data systematically miss the couples who were distressed, never sought help, and eventually experienced relationship improvement that made them glad they never went.

Peer-reviewed
At 5-year follow-up, 25.7% of IBCT and 27.9% of TBCT couples were separated or divorced; 48% (combined average) showed clinically significant improvement; effect sizes d=1.03 (IBCT) and d=0.92 (TBCT) for satisfaction vs pretreatment
Excerpt
“"At 5-year follow-up for marital satisfaction relative to pretreatment, effect sizes were d = 1.03 for IBCT and d = 0.92 for TBCT; 50.0% of IBCT couples and 45.9% of TBCT couples showed clinically significant improvement. 25.7% of IBCT couples and 27.9% of TBCT couples were separated or divorced."

Christensen, Atkins, Baucom & Yi (2010), Journal of Consulting and Clinical Psychology, 78(2):225-235. PMID 20350033. RCT of 134 seriously and chronically distressed married couples randomly assigned to ~8 months of IBCT or TBCT. At 5-year follow-up, marital status was obtained for all 134 couples; at least one partner in 119 (89%) completed satisfaction measures. Combined separation/divorce rate: (25.7 + 27.9) / 2 = 26.8%, rounded to 0.27. The action-side regret proxy uses 0.29 to include an estimated 2% of non-divorced couples who showed clinically significant deterioration at 5 years without yet separating, consistent with Lebow & Snyder (2022) reporting that deterioration or divorce occurs in roughly 35-50% of couples within 4-5 years (the lower bound of this range is ~35%). The 0.29 figure is a rounded lower-bound estimate; the 0.27 separation/divorce rate alone is the primary verified figure. None of these captures direct regret — a couple that divorces may still regard entering therapy as the right decision, and a couple that remains together but is unhappy may deeply regret having gone.

Baucom, Atkins, Rowe, Doss & Christensen (2015), Journal of Family Psychology, 28(5):711-720. PMC4324126. Same 134-couple RCT dataset with 5-year follow-up data from Christensen et al. (2010). The 56% figure (of those who improved at end of treatment, only 56% maintained improvement at 5 years) corroborates the action-side durability caveat: even among couples who responded to therapy, relapse is common. This source is included to show that the action-side regret proxy (0.29) is plausible given the high rate of deterioration even among initial treatment responders; it does not independently generate the 0.29 figure.

Grow Therapy / YouGov online panel, n=2,514 US adults 18+, fieldwork December 18-22, 2025, weighted to represent US adult population. The inaction-side regret proxy of 0.42 is anchored to the US population divorce rate as a structural lower bound: approximately 39-42% of first marriages end in divorce (CDC/NCHS data). Among the 66% of US adults who have never attended or considered couple therapy, the 0.42 figure represents the fraction expected to experience either divorce or persistent unresolved relationship distress without intervention. Lebow & Snyder (2022, Family Process) found "little improvement in relationship satisfaction among distressed couples who do not receive therapy," meaning the no-treatment deterioration rate for distressed couples (the relevant sub-population) is substantially higher than the general population divorce rate. The 0.42 is thus a conservative lower-bound proxy for inaction harm: the actual inaction regret rate among relationship-distressed non-attenders is likely higher, but 0.42 is the most defensible figure anchored to a direct measurable outcome (US divorce rate) rather than a model-derived estimate. No large-scale survey directly asks non-attenders whether they regret not having sought therapy. The 0.42 value should be read as a lower-bound proxy, not a precisely measured rate.

Doherty WJ, Harris SM, Hall EL, Hubbard AK (2021), Journal of Marital and Family Therapy, 47(4):882-890. doi: 10.1111/jmft.12479. PMID 33411353. N=270 couples attending couple therapy, N=101 in individual therapy for relationship problems. This study is included as the inaction-side corroborating source because the 2.68-year average delay shows that even couples who eventually seek help do so after extended periods of unresolved distress. For the much larger share of distressed couples who never seek therapy at all (66% per the Grow Therapy/YouGov survey), the period of unresolved distress is indefinite. This supports the inaction regret direction: delayed or absent help-seeking is the modal behaviour, and the accumulated period of relationship deterioration before entry (or without it) is the most plausible source of inaction regret.
Caveats
PROXY MEASUREMENTS ON BOTH SIDES. Neither side uses a direct regret survey. The action-side rate (0.29) is drawn from Christensen et al.'s 5-year RCT follow-up of 134 seriously and chronically distressed married couples: the combined separation/divorce rate of ~27% is used as the primary proxy, with the 0.29 rounding up slightly to capture deteriorated-but-not-yet-divorced couples consistent with Lebow & Snyder (2022). Divorce or deterioration is not equivalent to regretting having attended therapy: couples who entered therapy specifically to manage a healthy separation may not regret going, and the 56% of divorced attendees in the Grow Therapy survey who described it as a "final attempt" implies purposeful attendance, not naivety. The inaction-side rate (0.42) is anchored to the US population divorce rate (~39-42%, CDC/NCHS) as a structural lower bound. Among relationship-distressed non-attenders specifically, deterioration rates are higher than the general population divorce rate; Lebow & Snyder (2022, Family Process) note "little improvement in relationship satisfaction among distressed couples who do not receive therapy," making 0.42 a conservative floor rather than a central estimate. No large-scale nationally representative survey directly measures regret among couples who never sought therapy; the inaction proxy therefore unavoidably conflates lack of help-seeking with relationship harm, which are correlated but not identical. The two populations are not directly comparable: the action side draws from an RCT of 134 chronically and seriously distressed couples who volunteered for a clinical trial (a selected, help-motivated, high-distress sample), while the inaction side is inferred from the US adult population including couples whose relationships are not in acute distress. The Christensen et al. sample may overstate action-side deterioration relative to real-world clinical samples; conversely the 0.42 inaction floor probably understates deterioration among the distressed sub-population most relevant to the decision framed here. This entry is distinct from therapy-vs-no-therapy.mdx (individual therapy): couple therapy requires both partners' simultaneous participation, is contraindicated in active domestic violence situations, and has a different evidence base and mechanism of change. The Doherty et al. (2021) finding that couples wait an average of 2.68 years before entering therapy (not the widely cited but unsupported six years) modestly reduces the inaction framing's intensity: the typical help-seeking couple does not wait indefinitely, though most distressed couples never seek help at all.
