摘　　要：目的初步修订系统家庭动力学自评量表（SSFD）学生测试版,并评价其信度和效度,分析该量表在学生群体中的适用性。方法在SSFD量表的基础上,结合青少年特点初步对该量表的理论结构进行修订,并采用项目分析、验证性因素分析和信效度检验方法对多阶段分层整群随机抽取的5188名陕西省中学生和大学生的系统家庭动力进行分析,验证该量表理论结构的合理性。结果修订后的SSFD量表学生测试版具有较好的项目区分度,家庭氛围、个性化、系统逻辑、疾病观念4个领域与总分的相关系数分别为0.73、0.72、0.55、0.70,各条目与所属领域的相关系数均〉0.4（均P〈0.01）;量表总体Cronbach＇sα系数和分半信度分别为0.81和0.67,4个领域的Cronbach＇sα系数为0.65~0.75,分半信度为0.42~0.63;探索性因子分析结果显示,SSFD量表学生测试版4个公因子的累计方差贡献率为42.80%;效标效度检验结果显示,家庭氛围、个性化、系统逻辑、疾病观念4个领域和总体幸福感得分分别为（32.55±15.71）、（37.02±17.32）、（57.14±17.50）、（51.69±15.82）和（77.25±24.89）分,4个领域与总体幸福感得分均呈正相关（r=0.40、0.32、0.16、0.20,均P〈0.01）;陕西省不同特征学生比较,不同性别、文化程度、家庭月平均收入、户口类别、家庭人口数学生4个领域得分差异均有统计学意义（均P〈0.05）,量表具有较好的区分效度。结论修订的SSFD量表学生测试版在学生中的信度和效度指标均符合心理测量学的要求,可作为学生系统家庭动力研究的一个有效工具。Objective To revise Self-Rating Scale of Systemic Family Dynamics（ SSFD）-students testing version and to evaluate reliability and validity of the SSFD revised. Methods The theoretical structure of original SSFD was revised based on personality traits of adolescents. Using multi-stage stratified cluster sampling,5 188 high school and college students in Shaanxi province were tested with revised SSFD to assess the reliability and validity of the scale with item analysis and confirmatory factor analysis. Results Compared to the original version,the revised SSFD exhibits better item discrimination; the correlation coefficients of family atmosphere,individuation,system logic,and disease concept with the total score of the scale were 0. 73,0. 72,0. 55,and 0. 70 and the correlation coefficients of every item with its domain were all greater than 0. 4（ all P〈0. 01）. The Cronbach＇ s α coefficient and the split-half reliability of the whole scale were 0. 81 and 0. 67,respectively. The Cronbach＇ s α coefficients for the four domains ranged from 0. 65 to 0. 75,and those of split-half reliability ranged from 0. 42 to 0. 63. The results of exploratory factor analysis demonstrated the cumulative variance contribution rate of 4 common factors of the revised SSFD was 42. 80%; criterion validity test results showed that scores of family atmosphere,individuation,system logic,disease concepts,and overall well-being were 32. 55 ± 15. 71,37. 02 ±17. 32,57. 14 ± 17. 50,51. 69 ± 15. 82,and 77. 25 ± 24. 89,respectively. The scores of the four domains and the overall well-being score were positively correlated（ r = 0. 40,0. 32,0. 16,and 0. 20; all P〈0. 01）. There were significant differences in the scores of the four domains among the students of different gender,with various education level,average monthly household income,household type,and family size（ all P〈0. 05）,indicating that the revised SSFD has good discriminating validity. Conclusion The reliability and validity of the revised SSFD-students test
