Pearson correlation coefficient and regression analysis were used to analyze the data. The findings showed a negative and significant relationship between research capabilities (and its components) and information literacy (and its components) and research anxiety. Also, the results of regression analysis revealed that approximately 31% of the total variance of research anxiety could be predicted based on the research capabilities and information literacy and the variable of research capabilities contributed more. Therefore, it can be concluded that research capabilities and information literacy are associated with students’ research anxiety.
