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 Türkiye. While parental nominations are valuable, they may be less reliable than test results in identifying giftedness.

Summary

  • The SIGS-2 Home Rating Scale, now adapted into Turkish, is a valid and reliable tool for identifying gifted children from preschool onwards.

  • Parental ratings on the SIGS-2 Home Rating Scale demonstrate alignment with teacher nomination scores and children's nonverbal ability test results.

  • The SIGS-2 Home Rating Scale facilitates the early identification of gifted children and enhances the multi-assessment process by integrating parental insights, offering a more comprehensive evaluation of giftedness.
