The instrument has a crucial function in a research. The accuracy of the data taken is also influenced by the validity of the research instrument. The validity of the research instrument will also affect the accuracy of research conclusions. Therefore, before using an instrument to retrieve data, its validity and reliability must be tested. This study tested the validity and reliability of the questionnaire instrument of the student leadership style variables. The indicators used to compile the questionnaire statement items for the student leadership style variables based on the theory of Yukl (2015), Usman (2013), and Gunawan (2018), namely: autocratic; bureaucratic; diplomatic; participative; and free rein leader. Based on this theory, 10 items were developed to measure the student leadership style variables. The research sample was 35 students of UKM KSR PMI Unit Universitas Negeri Malang (student organizations engaged in the red cross). The formula used to test the validity is the Pearson Product Moment Correlation formula, while the formula used to test the reliability is the Cronbach's Alpha formula. The results of the validity analysis concluded that all statement items developed (10 items) had a probability value (α) < 0.05; so it can be concluded that the instrument is valid for measuring the variable student leadership style. The results of the reliability analysis showed that the value of r alpha = 0.799 > r table = 0.468; so it can be concluded that the instrument is reliable for measuring the variable student leadership style.
