Contemporary college students navigate the rapid currents of societal change, facing multifaceted pressures from academic demands, career challenges, and interpersonal relationships. Cultivating positive psychological qualities can help shape well-rounded personalities and moral sentiments, foster resilience, refine aesthetic sensibilities, and realize personal value and life purpose. Grounded in the "Five-Education Integration" strategic framework, this study examines the synergistic role of moral, intellectual, physical, aesthetic, and labor education in shaping students' positive psychological traits. It analyzes the unique contributions and interconnections of these educational components to develop an integrated "Five-in-One" cultivation pathway that combines value guidance, cognitive empowerment, physical conditioning, emotional nurturing, and practical skill development. The research aims to provide theoretical foundations and practical models for innovative mental health education in higher education institutions, supporting holistic student development and fostering qualities such as optimism, perseverance, and proactive responsibility.
