Abstract:
This study aims to adapt the Achievement Goal Questionnaire-Revised Form (AGQ-R) into Turkish and to examine its validity and reliability among middle school students. The sample comprised 527 students in grades 5 through 8, aged 10 to 15, drawn from various public schools. The adaptation process employed the back-translation method, which is widely accepted in the literature, followed by a thorough review for grammatical and punctuation accuracy. To ensure cultural appropriateness, expert feedback was obtained from a multidisciplinary panel within the faculty of education, which facilitated the identification and removal of culturally specific content from the scale items. Validity and reliability analyses were conducted using SPSS 25 and AMOS 22. The internal consistency of the scale was supported by a Cronbach’s alpha of α = 0.89, and corrected item-total correlations ranged from 0.525 to 0.644 across all subscales. In addition, the convergent validity and internal consistency of the constructs were confirmed using Average Variance Extracted (AVE) and Composite Reliability (CR) values. Confirmatory factor analysis supported the hypothesized four-factor structure (mastery-approach, mastery-avoidance, performance-approach, and performance-avoidance), demonstrating a good model fit (χ²/df = 2.145; RMSEA = 0.047; CFI = 0.978). These findings indicate that the Turkish version of the AGQ-R is a psychometrically sound tool for measuring achievement goal orientations among middle school students. It is recommended for use by researchers and educators to better understand and support student motivation in the Turkish educational context.
