Abstract: | The purpose of this study is to better understand the implications for using self‐reported grade point average (GPA) versus school‐record GPA in academic achievement research. First, we found that nearly half the youths interviewed overreported their GPAs by at least 2 half grades. Second, youth who overreported their GPAs also reported less psychological distress, more successful academic beliefs, and fewer problem behaviors. Third, we found that self‐reported GPA was associated with all 3 sets of variables, but school‐record GPA was associated with only problem behaviors. The findings suggest that it may be useful for researchers to consider how different measures of GPA may influence their results. |
