Domain-Specific Grammar Grit Questionnaire (DSGGQ) among Iranian
and Polish university students majoring in English. The DSGGQ was
developed based on the L2 grit scale proposed by Teimouri, Plonsky
and Tabandeh (2022. “L2 grit: Passion and perseverance for secondlanguage learning.” Language Teaching Research 26 (5): 893–918.
https://doi.org/10.1177/1362168820921895) and administered to a total
of 807 participants, 440 from Poland and 367 from Iran. The data
underwent confirmatory factor analysis (CFA) to assess the scale’s
psychometric characteristics. The differences in the levels of grit
between the Polish and Iranian students were also explored. The
results demonstrated that the DSGGQ has satisfactory psychometric
properties, and its structure proved to be invariant across nationality,
gender, and age group. In addition, there were significant differences in
grit levels between the two groups. Findings of this study suggest that
the DSGGQ can be a useful tool for measuring grit in the domain of
English grammar learning and can be applied in different cultural
contexts.</p>
