Azerbaijani adaptation of the WHO-5 wellbeing index: investigating its relationship with psychological distress, resilience, and life satisfaction.

Background: The WHO-5 Wellbeing Index is a widely used tool for assessing psychological well-being. Despite its global application, its adaptation and validation for the Azerbaijani population had not been previously explored. This study aims to fill this gap by adapting the WHO-5 Wellbeing Index for Azerbaijani adults and examining its relationship with psychological distress, resilience, and life satisfaction.
