Evaluation of the Psychometric Properties of the Mental Vulnerability Questionnaire in Undergraduate Students.

ABSTRACT

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.
