The concept of grit has becomea widely investigated topic in mental health and education in recent
years. This study aims to develop a tool for measuring grit in high school and university students
and to examine the measurement invariance of the developed scale on two different groups. A total
of 586 high school students (411 female, 70%; 175 male, 30%) and 639 (437 female, 63%; 202 male,
37%) university students participated in the study. Grit Scale, Short Grit Scale, and Beck
Hopelessness Scale were used as data collection tools in the study. The exploratory factor analysis
results indicated that 14-item Grit Scale with three sub-dimensions explained 61.88% of the variance.
The dimensions in the scale were named Perseverance, Commitment to Goals, and Consistency of
Interest. Confirmatory factor analysis showed that the three-dimensional structure of the Grit Scale
fit the data well, with measurement invariance between the high school and university student
groups. Cronbach’s alpha internal consistency coefficients of the total score and sub-dimensions of
the scale were found as .87, .85, .84, and .75, respectively. Convergent validity was evaluated by
calculating the zero-order correlation between the Grit Scale and Short Grit Scale and a significantly
high positive correlation was found (r= .655, p< .001). Divergent validity was evaluated by examining
the relationship between Grit Scale and the Beck Hopelessness Scale and a mild correlation was
found (r= -.484, p< .001). The study revealed that the Grit Scale is a valid and reliable measurement
tool that can be used with adolescents and university students.
