| 目的 了解医学生社交网络使用情况，制定社交网络使用情况量表（social networking using status scale，SNUSS）并对其信效度进行评价。方法 在2018年3月采取整群抽样的方法进行问卷调查，回收有效问卷665份。在间隔2个月后对46名受试对象进行量表的重测。采用因子分析、相关分析、t检验等计算量表的结构效度和内容效度以评价量表效度，采用内部一致性信度、折半信度和重测信度评价量表的信度。结果 探索性因子分析，分析结果量表为2个维度：维持现有社会关系社交网络使用情况维度（维持维度）和拓宽朋友圈社交网络使用情况维度（拓宽维度）。验证性因子显示，各条目因子负荷值大于0.500（P<0.05），该模型拟合情况优良（χ2/df=2.873，GFI=0.970，CFI=0.971，RMSEA=0.074）。领悟社会支持量表与社交网络使用情况量表相关系数r为0.295，条目水平的内容效度均等于0.90，量表水平的内容效度为0.90，内部一致性信度为0.764，折半信度为0.555，重测信度为0.526。结论 SNUSS在医学生群体中对于社交网络使用情况有良好的信度和效度，且与感知的社会支持有相关性。 |

| Objective To understand the social networking using status of medical students, develop the social networking using status scale (SNUSS) and evaluate its reliability and validity. Methods In March 2018, 665 valid questionnaires were collected via cluster sampling. The scale was retest in 46 subjects after an interval of 2 months. Factor analysis, correlation analysis and t-test were used to calculate the structure validity and content validity of the scale to evaluate the scale validity, and internal consistency reliability, broken half reliability and retest reliability were used to evaluate the scale reliability. Results The result of exploratory factor analysis showed NSUSS had two subscales: the dimension of maintaining existing social relations and social network use and the dimension of expanding circle of friends and social network use. The result of confirmatory factor analysis showed that the factor load value of each item was greater than 0.500 (P < 0.05), and the model fitted well (χ2/df = 2.873, GFI = 0.970, CFI = 0.971, RMSEA = 0.074). The r value of correlation between SNUSS and MSPSS was 0.295. I-CVIs were all equal to 0.90, and S-CVI was 0.90, the internal consistency reliability was 0.764, the split-half reliability was 0.555, and the retest reliability was 0.526. Conclusion SNUSS has good reliability and validity for the use of social network among medical college students, and the use of social network is related to perceived social support. |
