The cognitive autonomy and self-evaluation (CASE©) inventory: validation in Indonesian adolescents

Introduction: The CASE© Inventory assesses adolescents’ cognitive autonomy through five aspects: evaluative thinking, voicing opinions, decision-making, self-assessment, and comparative validation. While widely adapted across contexts, no version exists specifically for Indonesian adolescents. Objectives: This study aimed to adapt and validate an Indonesian version of the CASE© Inventory. Methods: The adaptation, which followed International Test Commission guidelines, involved translation, expert reviews, cognitive interviews, and psychometric evaluation. Data were collected from 214 adolescents (175 females, 39 males; mean age = 18.55, SD = 1.197). Results: The Indonesian CASE© Inventory demonstrated good international consistency (α = 0.779) across four factors: evaluative thinking (α = 0.812), decision-making (α = 0.708), self-assessment (α = 0.716), and comparative validation (α = 0.658). Confirmatory factor analysis indicated a good model fit (CFI = 0.915, TLI = 0.902, RMSEA = 0.042, SRMR = 0.061, GFI = 0.990). Positive correlations appeared between four factors of cognitive autonomy and positive affect (r = 0.141 to 0.339), while the comparative validation factor negatively correlated with positive affect (r = −0.124). Negative correlations were found between all factors and negative affect (r = −0.026 to −0.407). Conclusion: The Indonesian CASE© Inventory appeared to be a valid instrument for assessing the five factors determining cognitive autonomy in the Indonesian adolescent population.
