考评大学生信息查寻自我效能初步量表的信度、效度等统计学指标,研制适合我国大学生的信息查寻自我效能量表。按照编制原则初步制定信息查寻自我效能感量表,应用初步量表对142名被试进行预测,修订结果,形成正式量表。再对294名大学生进行正式测试,对其结果进行分析。结果显示,量表条目的平均通俗率为0.43,在0.50左右;各项目区分度均达到0.4以上,区分度理想。因子分析表明6个因子与量表设计的因素大致吻合。量表的一致性信度α系数是0.819;除因素4“周围环境”外,各维度的信度均大于0.70,各因素的内部一致性信度较高。得出结论:大学生信息查寻自我效能量表具有较好的信度、效度。
To evaluate the reliability, validity and other statistical indicators of the initial scale of self-efficacy search of college students’ information, and to develop a self-efficacy questionnaire suitable for Chinese college students. In accordance with the principle of preparation of the initial development of information search self-efficacy scale, the initial scale of 142 subjects were predicted, revised results to form a formal scale. Then 294 college students formal tests, the results were analyzed. The results showed that the average popular rate of the items in the scale was 0.43, which was about 0.50; the degree of division of each item was above 0.4, and the degree of differentiation was ideal. Factor analysis showed that the six factors roughly agree with the scale design. The α coefficient of the consistency reliability of the scale is 0.819. The reliability of each dimension is greater than 0.70 except for the factor 4 “surroundings ”, and the internal consistency reliability of each factor is relatively high. Concluded that: college students self-efficacy information search look-up table has good reliability and validity.
