Over 95% of psychometric instruments were built for WEIRD societies. Isomro transforms them into culturally valid tools — with AI-driven adaptation and full statistical validation.

The Global Validity Gap
Translation changes words. Adaptation preserves meaning, structure, and cultural logic. Most organizations still rely on translation alone — producing data that is linguistically correct but psychometrically invalid.
Constructs like anxiety, resilience, and motivation may be universal in formula but differ in structure across cultures. Translated scales routinely lose their factor structure.
Differential Item Functioning (DIF) means the same item can measure differently across groups — biasing scores and undermining comparability across countries.
Invalid instruments lead to misdiagnosis, biased hiring, failed interventions, and unreliable research — costing billions annually across healthcare, HR, and international development.
"The world's next billion data points will come from the Global South. Without new infrastructure, they will be systematically distorted."
How It Works
Upload your scale. Get a culturally adapted, statistically validated instrument — powered by AI agents and a full R statistical engine.
AI analyzes each item for cultural assumptions — context level, power distance, idioms, and Hofstede-based risk scoring.
Forward adaptation, reconciliation, and back-translation — preserving meaning while aligning with local communication norms.
Expert review and harmonization ensure the construct retains its factor structure, dimensionality, and conceptual boundaries.
CFA, DIF analysis, IRT modeling, and reliability testing via a dedicated R statistical engine — not approximations.
Pilot testing confirms configural, metric, and scalar invariance — the gold standard for global measurement equivalence.
Key Capabilities
Not a translation tool. A complete adaptation platform with real statistical validation.
Multi-agent workflow following ITC Guidelines — from cultural analysis through back-translation to final validation.
Dedicated R microservice running lavaan, psych, mirt, difR, and semTools — real psychometric computation, not LLM approximations.
Mantel-Haenszel and logistic regression detect items that function differently across cultural groups, with ETS A/B/C classification.
Graded Response and Rasch models provide item-level difficulty, discrimination, and information curves with multiple theta estimation methods.
Multi-group CFA tests configural, metric, and scalar invariance — the gold standard for cross-cultural comparability.
Three tiers of settings — from quick defaults to advanced parameters like theta estimation, omega extraction, and custom ETS thresholds.
Use Cases
Clinical Research
Well-being scales referencing "feeling blue" or "losing interest" don't map onto emotional expression norms in Sub-Saharan Africa. Symptom scales lose sensitivity, compromising endpoint reliability.
Global HR
Western personality scales over-penalize collectivist communication patterns, misclassifying candidates as "low initiative" or "low assertiveness" in high-context cultures.
International Development
NGOs measuring resilience, wellbeing, or educational outcomes across countries need scales that produce comparable scores — not translated approximations that mask real differences.
