Scientific validation of Sapiens' Self-Assessments

Sapiens has selected scientifically validated assessments based on 4 criteria: 

• Reliability: internal consistency (e.g., Cronbach’s α), test–retest stability.
• Construct validity: factor structure and expected relationships with related constructs (e.g., burnout)
• Criterion validity / diagnostic accuracy (when applicable): performance against a reference standard (structured clinical interview, clinician ratings, or established case definitions), often summarized by sensitivity/specificity at a cutoff.
• Responsiveness: ability to detect change over time (important for interventions).

Important: many of the tools in a wellness setting are not designed as diagnostic tests (e.g., Sapiens doesn't diagnose depression or other diseases), so “sensitivity/specificity” is either not applicable (purely dimensional scales) or is cutoff- and population-dependent (screening tools). At Sapiens, results are interpreted as risk signals and severity gradients to guide prevention and follow-up - never as a medical diagnosis.
