Academic Grit Scale: Adaptation, Validity, and Reliability Study for Middle and High School Students

The aim of this study is to adapt the Academic Grit Scale, developed by Clark and Malecki (2019), into Turkish. Validity and reliability studies for the adaptation process were conducted on two different groups. The first participant group consisted of middle school students, while the second participant group included high school students. Middle and high school students from various schools were selected using an appropriate sampling method and included in the study sample. Confirmatory Factor Analysis (CFA) was applied to test whether the construct was confirmed within these two distinct sample groups. According to the CFA results, the scale’s 10-item, single-factor structure demonstrated good fit indices. Internal consistency coefficients of the Academic Grit Scale were calculated using Cronbach’s alpha reliability coefficient. Accordingly, the internal consistency coefficient was determined to be .89 for middle school students, .92 for high school students, and .92 for the entire sample. After determining the internal consistency coefficients, the test-retest reliability of the scale was also calculated. Test-retest reliability was found to be .82 for the middle school group, .86 for the high school group, and .85 for the entire sample. As a result of the study, the Academic Grit Scale was found to be a valid and reliable measurement tool for middle and high school students.
