Abstract

This study adapts the "Scales for Identifying Gifted Students (SIGS-2)" into Turkish for use from preschool onward, specifically during the candidate nomination stage. Conducted with 974 parents (675 mothers, 299 fathers) of children aged 5-10, it employs Confirmatory Factor Analysis (CFA) to evaluate the scale's structure and reliability. CFA results show excellent fit indices (CFI = 0.998, GFI = 0.994, IFI = 0.998, NFI = 0.993, NNFI = 0.998, RFI = 0.993) and an RMSEA of 0.017, indicating good model fit. Factor loadings ranged from 0.36 to 0.89, and item-total correlations were between 0.32 and 0.79, demonstrating effective discrimination. Reliability coefficients were high, with Cronbach's alpha, McDonald's omega, and Composite Reliability (CR) ranging from 0.87 to 0.96. The SIGS-2 Home Rating Scale aligns well with existing measures and reflects changes in IQ levels, showing its suitability for assessing gifted children in T & uuml;rkiye. While parental nominations are valuable, they may be less reliable than test results in identifying giftedness.
