WHAT THE TEST MEASURES

About This Assessment

Psychological Safety-Vulnerability Questionnaire, S-I Test

Psychological Safety–Insecurity Questionnaire (S-I) Test - Symptoms and Signs

security

This questionnaire is designed to assess an individual’s perceived sense of emotional security versus vulnerability in their internal experience and environment. The Psychological Safety-Insecurity Questionnaire (S-I) uses self-report statements to capture perceived safety, insecurity, and related affective reactions. It is attributed to William A. Kahn.

The measure includes 75 items and typically requires about 14 minutes to complete. Responses may help clinicians and researchers identify themes related to psychological safety, perceived threat, and subjective insecurity that can inform case formulation and guide follow-up assessment. Interpretation should consider the respondent’s context, current stressors, and the broader assessment battery, as the Psychological Safety-Insecurity Questionnaire (S-I) is best used as one component of a comprehensive evaluation.
