A Study on the Structure of Intelligence Measured by the K-WPPSI-IV

Abstract

Objective: This study examined the construct validity of K-WPPSI-IV. Factor structures of the structures of the K-WPPSI-IV full scale as well as primary index scales for two age ranges (2 years, 6 months to 3 years, 11 months; 4 years to 7 years, 7 months) were examined. Methods: Data were collected from 1,700 children aged 2 years, 6 months to 7 years, 7 months during the K-WPPSI-IV standardization. Confirmatory factor analyses were conducted using the K-WPPSI-IV subtest performances with maximum likelihood estimation using Amos 18. Results: First, the three-factor model (verbal comprehension, visual spatial, and working memory) fitted best for the younger age range. However, the five-factor model (verbal comprehension, visual spatial, fluid reasoning, working memory, and processing speed) fitted best for the older age range. Residuals suggest the presence of two nested subfactors within the verbal comprehension factor (broad/expressive and focused/simple). Second, the confirmatory factor analysis on primary index subtests identified factors that account for the intercorrelations among the reduced sets of primary index subtests. Conclusion: The findings showed that the theoretical structures of WPPSI-IV subtests were confirmed within K-WPPSI-IV.

Effects of intelligence and approximate number system on the non-symbolic division ability in preschoolers

“…We used the K-WPPSI-IV to examine children's intelligence and sub-scale scores (Lee et al, 2016). Unlike previous K-WPPSI versions, which can only examine fluid, crystallized, and total intelligence, we chose the latest version to examine verbal comprehension, visuospatial, fluid reasoning, and processing speed abilities (Lee et al, 2016).…”

Of the 15 subtests contained in the K-WPPSI-IV, 10 subtests, comprising six basic subtests and four supplementary subtests, were used to measure the participants' total intelligence and five sub-indexes of intelligence (verbal comprehension index, visuospatial index, fluid reasoning index, WM index, and processing speed index, respectively).…”

“…어머니와의 애착은 또래지위에도 영향력 이 크며 (Park & Chung, 2012), 이후 청소년기의 또래 애착 및 외로움 지수와도 관련성이 있다고 보고되었다 (Jeon & Lee, 2000). (Lee, Park, & Rah, 1997;Posada et al, 1995). (Choi, 2013;Han, 2008;Kim, 2010;Lee & Shin, 2003;Son, 2000;Son, 2001) (Kim, 1994;Roh, 1995) Ⅲ.…”
