In literature, individual vulnerability to stress is a predictive factor of a higher risk of developing stress-related disorders and mental health problems. The Stress Vulnerability Questionnaire (23QVS; Serra, 2000, 2004) is a 23-item scale, measuring vulnerability to emotional and social adverse and stressful situations, and overall life satisfaction.

The purpose of this study was to assess the psychometric properties of a Russian version of the 23QVS in a sample of Russian-speaking immigrants residing in Portugal.

The 23QVS was administered to Russian-speaking immigrants in 12 Local Immigrant Support Centers in Portugal, along with a number of other self-report tests as part of a larger mental health status immigrants' study.

The Russian version of the 23QVS has an internally consistent measure Cronbach's α, 710 for the total scale (Item 7 was excluded). PCA was carried out in order to re-examine the factor structure of the scale. Seven factors were identified, overall matching the ones foreseen by the author of the scale.

The findings suggest that the Russian version of the 23 QVS addressed adequately the original concepts and dimensions, and demonstrated a high level of equivalence with the original version.
