青少年抑郁作为全球性公共卫生问题,其高发病率对身心健康与学业发展构成显著威胁。基于生态学理论,家庭、学校及社区等微系统中的多重因素交互影响抑郁发生发展:家庭冲突、不良教养方式、学业压力、同伴侵害及网络过度使用为主要风险因素;而亲子亲合、心理韧性、学校联结、友谊质量及社区支持等构成关键保护性因素。防控策略需整合多方资源:家庭应构建支持性教养模式,学校需推行多元评价体系与心理健康服务,社会应完善心理支持网络并净化网络环境。通过家校社协同干预,可有效降低抑郁风险,促进青少年心理健康发展。As a global public health problem, the high incidence of adolescent depression poses a significant threat to physical and mental health and academic development. Based on the ecological theory, multiple factors in family, school and community micro-systems interact to influence the occurrence and development of depression: family conflict, inappropriate parenting styles, academic pressure, peer victimization and internet overuse are the main risk factors;parent-child affinity, psychological resilience, school connection, friendship quality and community support are the key protective factors. Prevention and control strategies need to integrate various resources: families should build supportive parenting models, schools should implement multiple evaluation systems and mental health services, and society should improve the psychological support network and purify the network environment. Through the cooperative intervention of family, school and community, the risk of depression can be effectively reduced and the mental health of teenagers can be promoted.
