BACKGROUND/AIM: One mission of medical faculties is training scientists equipped with the necessary knowledge, skills, and attitudes, who can evaluate the scientific research. The aim was to develop a scale for evaluating the level of scientific competence and activity in research assistants.
The study is a methodological study, conducted in October 2023-May 2024, with 299 research assistants working at Ankara University Faculty of Medicine. The reliability was assessed by item-total correlation and Cronbach-alpha coefficient; construct validity was assessed by EFA. In EFA, principal component analysis, Varimax rotation were used. KMO and Bartlett test p-value were calculated. Groups with eigenvalues greater than one were determined as factors. The ability of the scale score to determine the level of scientific competence and activity was examined by ROC curve analysis. SPSS 30.0 was used; significance was taken as p < 0.05.
KMO value is 0.945, Bartlett's test p is <0.001. Seven items were removed. As a result of Varimax rotation, four sub-dimensions were determined; factor 1 (fourteen items), factor 2 (eight items), factor 3 (four items), factor 4 (three items). Cronbach's alpha coefficient is 0.960, item-total correlation coefficients are greater than 0.3. The mean score was 91.23 ± 23.10. According to the ROC analysis for participation in at least one publication/project, the cut-off point was 92.
The Scientific Competence and Activity Scale consists of 29 items in 4 subdimensions, it is valid, reliable. To generalize its validity and reliability, it is crucial to test the theoretical structure of the scale in various groups.
背景/目的：医学院校的一项任务是培养具备必要知识、技能和态度的科学家，使其能够评估科学研究。目的是制定一个评估研究助理科学能力和研究活动水平的量表。
本研究为方法学研究，于2023年10月至2024年5月进行，研究对象为安卡拉大学医学院的299名研究助理。通过项目-总分相关性和克朗巴赫α系数评估信度；通过探索性因子分析（EFA）评估结构效度。在EFA中，使用主成分分析和方差最大化旋转。计算KMO和巴特利特检验p值。将特征值大于1的组确定为因子。通过ROC曲线分析检验量表得分确定科学能力和活动水平的能力。使用SPSS 30.0；显著性水平设定为p < 0.05。
KMO值为0.945，巴特利特检验p值<0.001。删除了7个项目。经过方差最大化旋转，确定了四个子维度；因子1（14个项目），因子2（8个项目），因子3（4个项目），因子4（3个项目）。克朗巴赫α系数为0.960，项目-总分相关系数大于0.3。平均分为91.23 ± 23.10。根据参与至少一项出版物/项目的ROC分析，临界值为92。
科学能力和活动量表由4个子维度的29个项目组成，有效且可靠。为了推广其有效性和可靠性，在不同群体中测试量表的理论结构至关重要。
