Welk deel van Amerikaanse volwassenen dat een ernstige depressie of angststoornis ontwikkelt, ontvangt minstens een jaar lang geen geestelijke gezondheidszorg?
Among UK adults who have had therapy, 27% did not find it helpful (BACP/YouGov 2025, n=5,150); among US adults who have never sought mental health care, approximately 33% express latent demand — they want care but have not pursued it (APA/Harris Poll 2025, n=1,076). The bilateral comparison is directionally consistent with Gilovich and Medvec’s inaction-dominance model, but the 6-percentage-point gap is computed from incomparable populations — UK therapy-attenders versus US non-attenders — and should not be read as a precise effect size. The pattern is classified as balanced: the signal points toward inaction carrying more regret, but the cross-national measurement gap prevents a stronger directional claim.
The data-quality limitations are layered. The action-side BACP figure is the stronger instrument: a large, nationally representative YouGov survey asking therapy-attenders to assess their own outcomes. Its weakness is framing — “not helpful” captures a broad range of outcomes from genuine harm to mild disappointment, and the 27% unhelpfulness rate sits well above the 5.2% lasting-harm rate found in Crawford et al.’s NHS patient survey (n=14,587), confirming that most of the 27% experienced disappointment rather than lasting damage. The inaction-side rate is a derived figure: 17% of all US adults said they want mental health care but have not sought it, out of 51% who had never sought care, yielding 33% latent demand among non-attenders. Latent demand is prospective (want to go) rather than retrospective (wish I had gone), which likely understates actual regret in older cohorts where the opportunity cost has already accumulated.
Two structural confounders qualify any strong directional claim. First, access barriers make much inaction involuntary: NHS England waiting lists, US insurance gaps, cost, and persistent stigma mean that a share of non-attenders who want care cannot readily obtain it, conflating structural barriers with personal decision regret. Second, cross-national asymmetry in the data — UK for the action side, US for the inaction side — introduces noise because NHS cost-free access and US insurance-dependent access produce different selection effects in who enters therapy and who doesn’t. Within those limits, the data are consistent with the established finding that long-run regret accumulates more on the side of inaction than action, though the effect size here is too small to carry strong causal weight.

Berekening
BACP/YouGov 2025 Public Perceptions Survey (n=5,150 UK adults, nationally representative). 73% of therapy-attenders found therapy helpful, implying 27% did not (1 - 0.73 = 0.27). This is used as the action-side regret proxy: therapy-attenders who did not find treatment helpful are the subgroup most likely to regret having attended. "Not helpful" and "regret going" are not the same construct — a person can find therapy emotionally challenging but ultimately beneficial, and a person can find a single course unhelpful without regretting the attempt. The 27% figure likely overstates harm-based regret and understates indifference-based outcomes. D3 score: 3 (real survey measuring helpfulness, a recognized proxy for regret rather than a direct regret instrument). Used as the primary action-side rate because it is the largest nationally representative UK survey measuring therapy outcome from the patient's perspective.

Berekening
Crawford et al. (2016) surveyed 14,587 NHS patients who received psychotherapy across 184 services and found 5.2% reported lasting negative effects. This is the largest published national survey of therapy harm and provides a conservative floor for harm-based regret. The 5.2% rate sits well below the BACP 2025 "not helpful" figure of 27%, confirming that lasting harm is a smaller subcomponent of overall treatment dissatisfaction. This source corroborates that the action-side floor for serious harm-based regret is low. Included as a corroborating peer-reviewed source; the primary action-side rate (0.27) is drawn from the BACP 2025 survey.

Berekening
APA/Harris Poll 2025 (n=1,076 US adults, nationally representative, April 18-21 2025). The survey identified three mutually exclusive groups: those who sought care in the past (45%), those who want to in the future but haven't (17%), and those who never sought and don't want to (34%). The remaining ~4% are likely currently in care or did not respond. Among non-attenders (17% + 34% = 51% of the sample), 17/51 = 33% express latent demand (want care but haven't sought it). This 33% is used as the inaction-side regret proxy: non-attenders with latent demand are the subgroup most likely to retrospectively regret not having sought help. Construct limitation: "want care in the future" is not equivalent to "regret not having gone already" — latent demand is a forward-looking aspiration, while regret is a backward-looking counterfactual. Access barriers (cost, insurance, availability) mean some latent demand reflects structural obstacles rather than personal decision regret. Cross-national note: this is US data, not UK; the UK setting for the action side has different access structures (NHS, means-tested IAPT waitlists). UK latent demand data were searched across BACP/YouGov, MIND UK, Mental Health Foundation, NHS APMS 2023-24, and Rethink Mental Illness; no comparable nationally representative instrument was found that asked non-attenders directly about latent demand. The APA/Harris estimate (33%) is broadly consistent with UK treatment-gap literature and is used here as the best available nationally representative proxy.
Kanttekeningen
Geen van beide zijden van deze entry draagt een direct gemeten spijtpercentage. De actie-zijde 27% (BACP/YouGov 2025, n=5.150 UK-volwassenen) meet de fractie therapie-deelnemers die therapie niet behulpzaam vonden — "niet behulpzaam" en "spijt van gaan" zijn onderscheiden constructen. Een persoon kan therapie moeilijk of niet-conclusief vinden zonder spijt te hebben van de poging, en kan een enkele cursus onbehulpzaam vinden terwijl ze later van behandeling profiteren. BACP is een professionele vereniging voor therapeuten; zijn enquête werd in opdracht gegeven door een lichaam met financieel belang bij therapie-opname, wat de "behulpzame" framing kan vertekenen naar positieve uitkomsten. De inactie-zijde 33% (APA/Harris Poll 2025, n=1.076 Amerikaanse volwassenen) is een afgeleid latente-vraag percentage: 17% van alle Amerikaanse volwassenen willen zorg maar hebben het niet gezocht, gedeeld door 51% die nooit zorg hebben gezocht, geeft 33% van niet-deelnemers die vooruitkijkende vraag uiten (de resterende ~4% is waarschijnlijk momenteel in zorg of beantwoordde die vraag niet). Latente vraag is niet equivalent aan terugkijkende spijt. Een betekenisvol deel van inactie is onvrijwillig: NHS-wachttijden (Engeland), verzekeringskloven (VS), kostenbarrières en aanhoudende stigma beperken allemaal toegang ongeacht de voorkeur van het individu. Cross-nationale asymmetrie is een fundamentele beperking: de actie-zijde gebruikt UK-data (BACP/YouGov, Crawford NHS) en de inactie-zijde gebruikt Amerikaanse data (APA/Harris). Amerikaanse verzekeringsafhankelijke toegang en NHS kosten-vrije toegang produceren verschillende selectie-effecten in wie therapie binnenkomt en wie niet; de 6-procentpunt kloof tussen onvergelijkbare populaties moet niet worden gelezen als een precieze effectgrootte. Het gilovich_pattern wordt daarom geclassificeerd als gebalanceerd in plaats van inaction_dominates: het richtinggevende signaal is consistent met Gilovich en Medvec's inactie-dominantie model, maar de cross-nationale meetkloof betekent dat het verschil geen sterkere richtinggevende claim kan ondersteunen. Beide populaties tonen vergelijkbare therapie-opnamepercentages van ongeveer 35-45% levenslang.
