The Swedish model of health dialogues, which has been developed since 1985, aims to promote healthy behaviours, for prevention of cardiovascular disease, by inviting everyone in specific age groups to primary care for health dialogues combined with community-oriented activities. The health dialogue was performed by trained nurses, based on individual results from questionnaires on health behaviors and results of physiological measures, using visual pedagogic tools and motivational interviewing techniques.

Psychological resilience, as a core capacity for coping with adversity, and emotional competence, as a foundation for emotional regulation in social adaptation, are crucial for student development, with family functioning being a primary environmental factor closely associated with them. Research suggests that healthy family functioning may be associated with higher psychological resilience and emotional competence, while family dysfunction may be linked to increased psychological distress. However, the interconnected mechanisms among family functioning, psychological resilience, and emotional competence, as well as the roles of factors such as gender, urban-rural differences, and grade level, still require further exploration.&lt;/p&gt;&lt;p&gt;&lt;strong&gt;Objectives: &lt;/strong&gt;To explore the associations between family functioning, psychological resilience, and emotional competence among primary and secondary school students in Chengdu, Sichuan Province, and their underlying mechanisms.
