Cross-Cultural Psychological Support System for International Students in Chinese Vocational Colleges: An Evidence-Based Three-Tiered Intervention Framework

Abstract

The internationalization of China’s higher vocational education has brought increasing numbers of international students to vocational colleges, yet systematic psychological support systems tailored to this population remain underdeveloped. Drawing upon empirical data from 212 international students across three Jiangsu vocational colleges, this study proposes a three-tiered psychological support framework grounded in the evidence-based public health intervention model. Quantitative findings reveal that 47.6% of participants exhibit significant psychological adaptation difficulties, with HSK Level 3 serving as a critical threshold (below Level 3: M=2.76; Level 3+: M=3.31). Teacher support (β=0.245, p<0.001) and Chinese peer support (β=0.132, p=0.018) emerge as significant protective factors, while third-year students demonstrate the highest vulnerability (M=2.87, SD=0.76). Qualitative thematic analysis identifies four support gap clusters: language support insufficiency, mental health service inaccessibility, cultural orientation inadequacy, and professional identity underdevelopment. The proposed framework integrates universal prevention (Tier 1: institutional culture building, language support intensification, and teacher capacity development), targeted intervention (Tier 2: HSK Level 3 threshold-based academic support, structured peer mentoring, and cultural orientation enhancement), and intensive care (Tier 3: crisis identification protocols, multilingual counseling access, and final-year transition programs). This framework offers vocational institutions a data-driven, operationally feasible roadmap for transforming fragmented support efforts into a coordinated, evidence-based system that addresses the distinct needs of international students in skills-oriented, short-duration programs.
