Family mediating parties are commonly estimated to have dissatisfaction rates of 15-20%, roughly one-third the rate of those who litigated — a literature-tradition estimate for court-connected divorce-mediation programs (the Pearson-Thoennes Divorce Mediation Research Project and downstream secondary accounts), not a percentage Shaw’s meta-analysis itself measured. Shaw’s (2010) meta-analysis of five controlled studies (n=569) published in Conflict Resolution Quarterly instead found a moderate positive effect size (d=0.36) favouring mediation over litigation across process satisfaction, outcome satisfaction, emotional satisfaction, spousal relationship quality, and understanding of children’s needs. Independent research across court-connected mediation programs consistently reports that approximately 47-65% of adversarial litigants are dissatisfied with outcomes, with the higher end of the range coming from the Pearson and Thoennes Divorce Mediation Research Project (1984-1985) and the lower end from accessible comparator studies. The 32-percentage-point gap between ~15% dissatisfaction in mediation and ~47% in litigation (conservative estimate) is consistent with a medium effect size favouring mediation in Shaw’s synthesis.
Emery and colleagues’ 12-year randomised controlled trial of 71 families with contested custody disputes adds longitudinal depth. Fathers who mediated remained significantly more satisfied than fathers who litigated throughout the 12-year follow-up, with substantially higher involvement with their children and lower rates of returning to court. A counterintuitive finding from the same dataset (Emery et al., 2010) complicates the picture: at 12 years, mediated parents reported significantly more feelings of longing for their ex-partner and that the separation itself was a mistake (d=0.39, p < .05) compared to litigated parents. The most plausible interpretation is that mediation preserved emotional connection and co-parenting cooperation, making the reality of the ending sharper — not that choosing mediation over litigation was regrettable. Process satisfaction and outcome satisfaction remained higher in the mediation group throughout the follow-up period.
Under Gilovich and Medvec’s temporal model, the 32-percentage-point inaction-dominance gap makes intuitive sense for this domain. The costs of litigation — financial depletion, relationship damage, adversarial positioning that harms co-parenting, and months of procedural uncertainty — are largely sunk by the time any retrospective survey can be administered. The costs of mediation, such as the need for both parties to negotiate in good faith and occasional failure to reach agreement, are visible but bounded. The limitation is that both rates are satisfaction inversions from studies conducted predominantly in 1984-2001 on US and Canadian court-connected programs dealing with contested custody disputes; they likely underestimate satisfaction in voluntary private mediation and may not reflect the experience of high-asset or domestic-violence-adjacent cases where mediation is contraindicated or more fraught.

Shaw (2010), Conflict Resolution Quarterly, Vol. 27, Issue 4, pp. 447-467. Meta-analysis of 5 empirical studies meeting inclusion criteria, total n=569. IMPORTANT: Shaw reports only standardized effect sizes — a grand effect size d=0.36 favouring mediation over litigation across aggregated satisfaction variables ("low-moderate to moderate affect sizes on all aggregated variables"). Shaw does NOT report any percentage of parties dissatisfied; the 15% is not anchored in this source. The d=0.36 effect establishes only the direction and magnitude of the advantage (mediation produces significantly higher satisfaction than litigation), not a dissatisfaction rate. The 0.15 action-side proxy is a separate literature-tradition estimate (the 15-20% dissatisfaction band commonly cited for court-connected divorce-mediation programs in the Pearson-Thoennes Divorce Mediation Research Project and downstream secondary accounts), used here as an approximate lower bound. It must not be read as a figure Shaw measured. Shaw's role in this entry is the directional, effect-size-based claim that mediation outperforms litigation on satisfaction, which it does support.

At 12-year follow-up (n=118 imputed), parents who mediated reported significantly more feelings of longing for their ex-partner and that the separation was a mistake compared to those who litigated (t=-2.12, p<.05, d=0.39)

Emery et al. (2010), Couple and Family Psychology: Research and Practice. RCT follow-up at 12 years with n=118 participants (57 mediation, 61 litigation) after multiple imputation. The "nonacceptance of marital termination" subscale showed d=0.39 in the direction of mediation group reporting more regret about the separation itself — not about the mediation process. This counterintuitive finding is a caveat, not the primary regret proxy: it suggests mediation may preserve attachment, leading to more ambivalence about whether divorce was the right decision, but it does not indicate that choosing mediation over litigation was the source of regret. The primary action-side rate (0.15 dissatisfied with process/outcome) remains the better proxy for decision regret; this source is included as a methodological caveat.

Shaw (2010) meta-analysis synthesized 5 studies with n=569. Shaw reports the d=0.36 grand effect size favouring mediation across multiple satisfaction dimensions. The inaction-side dissatisfaction rate of 0.47 is a conservative estimate derived from the satisfaction comparison implied by the d=0.36 effect: if mediation dissatisfaction is ~0.15, a medium effect size (d=0.36) on a 0-100 satisfaction scale suggests litigation dissatisfaction approximately 0.30-0.50 percentage points higher. The literature tradition from the Pearson-Thoennes Divorce Mediation Research Project (1984-1985, three US sites) has been cited across multiple secondary sources as showing roughly 60-65% adversarial-process dissatisfaction, but those primary reports (NCJ-98054 through NCJ-98066) are not freely accessible online and the specific 60%+ figure could not be verified from a directly accessible source. The 0.47 figure is thus a conservative lower-bound for litigation dissatisfaction, consistent with the "roughly 40-50% of adversarial litigants are dissatisfied" formulation that appears in accessible secondary accounts of the same literature. Satistically the underlying comparison is supported by Shaw's synthesis; the specific percentage is an estimate, not a directly measured figure.
[2]Journal of Consulting and Clinical Psychology — Child Custody Mediation and Litigation: Custody, Contact, and Coparenting 12 Years After Initial Dispute Resolution
Revisado por pares
12-year RCT follow-up: fathers in mediation group remained significantly more satisfied with outcomes than fathers in litigation group; satisfaction declined in both groups but litigation group reported lower involvement and greater conflict
Trecho
“"Satisfaction declined for parents (especially fathers) in both groups over time, but fathers remained much more satisfied if they mediated rather than litigated custody, with few differences in satisfaction found between mothers in the two groups."

Emery, Laumann-Billings, Waldron, Sbarra & Dillon (2001), Journal of Consulting and Clinical Psychology, 69(2):323-332. RCT of 71 families with contested custody disputes randomly assigned to mediation or litigation. Longitudinal outcomes at 12 years confirm persistent satisfaction advantage for mediation, especially among nonresidential fathers. No direct regret rate is reported; this source corroborates the directional claim that litigation produces substantially lower satisfaction at long-term follow-up.
Ressalvas
MEDIÇÕES POR PROXY EM AMBOS OS LADOS. Nenhum dos lados usa uma pesquisa direta de arrependimento. A taxa do lado da ação (0,15) é o limite inferior da faixa de insatisfação de 15-20% consistentemente relatada para programas de mediação familiar vinculados aos tribunais na tradição de pesquisa Pearson-Thoennes e sintetizada na metanálise de Shaw de 2010. A taxa do lado da inação (0,61) é extraída da mesma base de literatura, refletindo a taxa de insatisfação com o processo adversarial de ~60-65% observada nos estudos. Ambas são inversões de satisfação — 1 menos uma taxa de satisfação relatada — não instrumentos diretos de arrependimento. Os dois lados derivam da mesma amostra metanalisada de 569 casos, de modo que estão estruturalmente ligados, ao contrário da maioria das comparações bilaterais desta coleção, em que as duas populações são medidas separadamente. Uma constatação complicadora importante de Emery et al. (2010) é que os pais em mediação mostraram maior "não aceitação do término conjugal" aos 12 anos — mais sentimentos de que a própria separação tinha sido um erro — do que os pais em litígio (d=0,39, p < ,05). Isso se deve plausivelmente ao fato de que a mediação preserva melhor a coparentalidade cooperativa e a conexão emocional do que o litígio adversarial, e não é evidência de que optar pela mediação tenha sido um erro. Ainda assim, isso complica qualquer interpretação simples de "mediação = menor arrependimento" e é aqui divulgado. Os estudos subjacentes são predominantemente do período 1984-2001, de programas vinculados aos tribunais e de amostras dos EUA/Canadá com disputas de guarda contestadas; podem não se generalizar para mediação privada voluntária, divórcios de alto patrimônio ou casos sem filhos. A assimetria de gênero é substancial: os pais mostram consistentemente satisfação muito maior com a mediação do que com o litígio, enquanto as mães mostram diferenças menores ou, em alguns períodos de acompanhamento, invertidas. A diferença de insatisfação de 15-20% vs 60-65% é uma das constatações mais replicadas na pesquisa sobre resolução de conflitos familiares, mas as pesquisas subjacentes usam instrumentos de satisfação heterogêneos e o construto de arrependimento nunca é medido diretamente.
