摘　　要：目的了解大学生社交恐怖症的焦虑素质、自我效能感、认知倾向以及血浆皮质醇水平的关系,探讨其可能的心理及生物学机制。方法对天津市某高校908名在校大学生进行社交恐怖症流行病学调查,并利用社交焦虑量表、焦虑-状态特质问卷、自我效能感量表以及认知倾向问卷对社交恐怖症患者和健康大学生进行病例对照研究,并检测血浆皮质醇水平。结果908名大学生中,社交恐怖症患者39例,发生率为4.3%,其中男性为2.5%,女性为1.8%;病例组社交焦虑得分、状态焦虑得分、特质焦虑得分(13.2±5.4),(51.4±8.3),(9.3±3.7)明显高于对照组(7.6±4.1),(33.2±5.4),(4.5±3.1),差异均有统计学意义(P<0.01);病例组自我效能感得分(22.3±6.7)明显低于对照组(27.5±5.8),差异有统计学意义(P<0.01);病例组血浆皮质醇水平(387.4±54.6)μg/L,明显高于对照组(264.3±48.5)μg/L,差异有统计学意义(P<0.01);相关分析显示,病例组社交焦虑程度与特质焦虑、状态焦虑、悲观因子、皮质醇水平呈正相关,与自我效能感量、乐观因子呈负相关。结论焦虑素质、认知倾向、自我效能感以及血浆皮质醇水平可能与大学生社交恐怖症相关。Objective To explore the prevalence of social phobia in college students and to analyze relationships between social phobia and anxiety trait, general self-efficacy, cognitive style, and plasma cortisol levels among college students. Methods With matched case-control study ,39 college students with social phobia and 48 healthy controls were investigated with the Social Anxiety Subscale of the Serf-Consciousness Scale （ SASS ）, State-Trait Anxiety Inventory （ STAI）, Cognitive Appraisal Orientation Test（CAOT） and General Serf-efficacy Scale（GSES）. The levels of plasma cord- sol of the subjects were detected. Results The prevalence of social phobia was 4.3% among 908 subjects. Compared with healthy controls,higher scores of SASS （ 13.2 ± 5.4 vs 7.6 ± 4. 1, t = 7.32）, SATI-S （51.4 ± 8.3 vs 33.2 ± 5.4, t = 17.42）, SATI-T（ 9. 3 ± 3.7 vs 4.5 ± 3. 1, t = 10. 27 ） and lower scores of GSES （ 22. 3 ± 6. 7 vs 27. 5± 5.8, t = - 3.98 ）, were observed in college students with social phobia（ P 〈 0. 01 ）. There was a higher level of plasma cortisol （387.4 ±54. 6 vs 264. 3 ±48.5 μg/L,t = 11.22） in the students with social phobia than in healthy controls（P 〈0. 01 ）. Correlation analysis showed significantly positive correlations between severity of social phobia and level of SATI, pessimism and plasma cortisol（ r = 0. 319 -0. 418 ,P 〈0. 05 ）, significantly negative correlation between severity of social phobia and level of GSES and optimism （ r = - 0. 427, r = - 0. 435, P 〈 0. 01 ）, significantly positive correlation between level of GSES and optimism （r = 0. 503 ,P 〈 0. 01 ）, and negative correlation between level of GSES and anxiety trait（ r = -0. 352, P 〈 0.01 ）. Conclusion Social phobia in college students may correlate with anxiety trait, cognitive style, general self-efficacy, and level of plasma cortisol.
