Russia Gets Its Own ACE-10: Validated in Psychiatric Inpatients, and the Numbers Are Telling
- First clinical validation of the Russian ACE-10 in psychiatric inpatients (n = 163, Bekhterev Institute, St. Petersburg) — filling a critical gap in Russian-language trauma assessment
- Internal consistency acceptable: Kuder-Richardson α₂₀ = 0.732, λ₆ = 0.94 — psychometrically sound for clinical screening
- Sample: 59.3% women, mean age 33.4 years, severe mental disorders — the validation was done in the population most likely to use the tool
- Published in Консультативная психология и психотерапия (МГППУ), the leading Russian clinical psychology journal — not a translated Western instrument, but a clinically adapted one
The Adverse Childhood Experiences questionnaire is arguably the most influential screening tool in modern mental health. The ACE score predicts everything from depression to heart disease, from substance use to early mortality. Tens of thousands of studies have used it. And until 2025, Russia — a country with 146 million people and its own distinct patterns of childhood adversity — did not have a clinically validated version.
Why clinical adaptation matters
Translation is not validation. A direct translation of the ACE-10 would produce Russian words that may not map onto the cultural experience of adverse childhood events in Russian populations. Emotional neglect, for instance, is conceptualized differently across cultures. Physical punishment exists on a different normative spectrum. Sexual abuse disclosure carries different stigma loads. Clinical adaptation means testing whether the items actually measure what they claim to measure in a Russian psychiatric population — not just whether the words make sense.
The Gerasimchuk et al. study from the Bekhterev National Medical Research Center (St. Petersburg) did this properly: 163 psychiatric inpatients, factor analysis, reliability testing, convergent validity assessment. The result is an instrument that Russian clinicians can use with confidence that the psychometric properties hold in their population.
The Kuder-Richardson coefficient
The α₂₀ = 0.732 is moderate — lower than some Western ACE validations. But ACE questionnaires typically show moderate internal consistency because the items assess different types of adverse experiences (abuse, neglect, household dysfunction) that do not necessarily co-occur. A person can have experienced physical abuse without sexual abuse, or parental substance use without parental incarceration. The λ₆ = 0.94 (Guttman's lambda-6, a more appropriate reliability estimate for dichotomous items) is excellent.
For your practice
For Russian-speaking clinicians: the ACE-10 is now validated for use in psychiatric settings. Use it as a screening tool at intake — the 10-item format takes 5 minutes. For researchers in Russia and CIS: this validation enables ACE-based research in Russian-speaking populations with a psychometrically grounded instrument. For international clinicians working with Russian-speaking patients: this adapted version is culturally more appropriate than a direct translation. Access via psyjournals.ru.
146 million people. The most studied screening tool in modern mental health. And until 2025, no validated Russian version existed.
Psychiatric inpatient sample — generalizability to outpatient or non-clinical populations unknown. Moderate sample size (n = 163). No test-retest reliability data. The ACE-10 captures only 10 categories of adversity — expanded ACE instruments (ACE-IQ) capture more, and a Russian ACE-IQ was validated separately in 2024.
