Purpose: Translate, adapt the language, and assess the psychometric properties of the Mental Vulnerability Questionnaire (MVQ) in a Portuguese population sample of young adults.
Design and methods: A psychometric validation study was performed. The sample comprised 166 undergraduate students. Factor analysis was applied to extract three indicators.
Findings: The MVQ showed divergent validity with the Positive Mental Health Questionnaire (p < .001) and convergent validity with the Mental Health Inventory including five items (p < .001). Reliability was verified through the assessment of internal consistency, evidencing positive outcomes (Cronbach's α = 0.81).
Practice implications: The MVQ shows psychometric properties enabling its adaptation to clinical practice and research, essential to an effective screening of mental vulnerability.
