作者 鲁青喜 《怀化学院学报》 1987年第5期131-133,共3页
昆虫是动物界中种类数目最多的一种动物。被描述的昆虫种类数目现已有780,000种以上,占已知动物的种类数的五分之三到五分之四,大多数昆虫的头部都生有一对触角。不同种类的昆虫,其触角的形状大小是不同的(有羽毛状、丝状、锯齿状……)... 昆虫是动物界中种类数目最多的一种动物。被描述的昆虫种类数目现已有780,000种以上,占已知动物的种类数的五分之三到五分之四,大多数昆虫的头部都生有一对触角。不同种类的昆虫,其触角的形状大小是不同的(有羽毛状、丝状、锯齿状……)。同一种类的昆虫,雌雄个体的触角在形态上也有差别。因此,触角的差别在昆虫的分类上和性别的鉴定上也是一个重要的依据。 展开更多

Objective:To translate and validate the Chinese version of the Work-Family-School Role Conflicts Scale(WFSRCs-S)among nurses with multiple roles.Methods:A sample of 233 registered nurses pursuing an advanced degree was recruited from 8 university hospitals in 5 cities in China from March to July 2016.The original scale of WFSRCs-S was translated into Chinese and revised to reflect cultural meaning,using standard translation methodology,and its reliability and validity were assessed.Results:The content validity index of the 12-item WFSRCs-S-Chinese was 0.83,and the item level of content validity index ranged from 0.79 to 1.00.The exploratory factor analysis yielded a three-factor solution(work-school-to-family role conflict,family-school-to-work role conflict,and work-family-toschool role conflict)and explained 71.9%of the total variance for WFSRCs-S-Chinese.The Cronbach's a coefficients for the total scale and the three sub-scales were 0.87,0.79,0.78,and 0.87.The confirmatory factor analysis revealed that the measurement model was satisfied,and the test-retest reliability of WFSRCs-S-Chinese was 0.85.The WFSRCs-S-Chinese score was positively associated with burnout(r=0.36,P<0.001)and negatively related to role-related social support(r=—0.18,P=0.046),thereby establishing concurrent validity.Conclusion:The reliability and construct validity of the WFSRCs-S-Chinese suggest that this scale could be useful to assess inter-role conflicts among nurses with multiple roles in China. 展开更多
