Validating a positive mental health measure with Portuguese adolescents and exploring associations with mental health perceived competencies

The Positive Mental Health Questionnaire proved to be a tool with good psychometric properties, adequately assessing adolescents' needs and the outcomes of mental health promotion initiatives. This work has also highlighted an opportunity to optimise adolescents' positive mental health, specifically in self-control, autonomy, and interpersonal relationship skills. Adolescents should be encouraged to care for their mental health and be informed that interacting with people with mental health problems does not present a significant risk to them. Through mental health training, adolescents' functioning can be enhanced over time, relying on the recognition of acquired skills. Findings can inform school-based and community strategies to promote adolescent mental health.
