Abstract Background With the accelerated development of social transformation and the digital age, college students are facing multiple pressures such as academic, employment, and interpersonal relationships. Their mental health problems are becoming increasingly prominent, and psychological crisis events occur frequently. The traditional psychological crisis intervention model for college students has limitations such as information lag, scattered resources, and low response efficiency. The flourishing development of digital technology provides a new path to solve this dilemma. The research aims to build a collaborative system centered on a digital platform that effectively integrates resources and strengths from families, schools, medical institutions, and communities (known as home school medical cooperatives) to achieve scientific prevention, precise identification, and efficient intervention of psychological crises among college students. Methods The research adopts a mixed research method that combines theory with practice. Firstly, through literature analysis and expert interviews, the pain points and digital requirements of existing collaborative models are identified. Then, an integrated digital collaboration platform was designed. The platform includes three core modules: student end, school management end, and collaboration end. Among them, the student end integrates regular psychological tests, dynamic emotional diaries, and resource navigation functions. The school management end is equipped with an algorithm based intelligent warning dashboard, task assignment, and process tracking system. The collaborative end provides a controllable information sharing portal, online consultation, and referral channel for home school medical cooperatives. The study selected a vocational and technical college to conduct a 12-month experimental research. Students were randomly divided into an experimental group (using a collaborative system, n = 1500) and a control group (using a traditional working mode, n = 1500). Collect process data through the platform and evaluate the effectiveness before and after the study using the Psychological Crisis Vulnerability Scale, Collaborative Satisfaction Questionnaire, and semi-structured interviews. Results The research results showed that during the intervention period, the identification time of high-risk students in the experimental group was shortened by an average of 67%. The sensitivity of the warning dashboard in predicting subsequent psychological crisis events is 82.5%, which is about 30% higher than traditional screening methods. The satisfaction survey showed that the satisfaction of school psychologists, participating parents, and cooperative medical institutions with the collaborative process was significantly higher than that of the traditional model (p.01). The post test showed that the total score of psychological crisis vulnerability of the experimental group students was significantly lower than that of the control group (p.05), and their psychological resilience factor score was significantly improved. Discussion The research results indicate that a digital based collaborative system between home, school, and medical institutions can effectively optimize workflow and improve the timeliness and precision of psychological crisis prevention and intervention for college students. The digital hub drives collaborative action through standardized processes, shifting prevention interventions from passive response to proactive management. Future research will focus on deepening cross regional medical school cooperation mechanisms and exploring more universal and low-cost technological solutions.
