A comparison of WPPSI-IV performance between Finland-Swedish minority children and the Scandinavian test norms: Findings from The FinSwed Study.

OBJECTIVE: The Swedish Wechsler Preschool and Primary Scale of Intelligence (WPPSI-IV) is commonly used for assessing young children belonging to the Swedish-speaking minority in Finland (Finland-Swedes), but there is no information about the generalizability of this test and its norms to this minority. Cross-cultural comparisons of WPPSI-IV are also scarce. We compared the performance of Finland-Swedish children to the Scandinavian norms of the Swedish WPPSI-IV and explored the relationship between sociodemographic factors (age, sex, parental education level, bilingualism) and the performance. METHOD: The Swedish WPPSI-IV was administered to 79 typically developing 5-6-year-old Finland-Swedish children assessed for The FinSwed Study. Their performance was compared to the Scandinavian norms using MANOVA, t-test, and confidence interval comparisons. Associations with sociodemographic variables were explored using regression analyses. RESULTS: Finland-Swedish children performed, on average, 1/3 SD higher than the Scandinavian norms, a difference which was statistically significant with medium-sized effects. However, individual subtests and indexes did not differ significantly from the norms. Significant associations with sociodemographic factors were found for some but not all index scores. CONCLUSIONS: This study provides clinically important information for using the Swedish WPPSI-IV with the Finland-Swedish minority and demonstrates aspects that clinicians working with this minority should take into account. The results are presumably partly explained by characteristics of the present sample, and partly by cultural and linguistic differences between the Finland-Swedish population and the Scandinavian countries. The findings also illustrate that cross-cultural differences in cognitive performance may be present even between similar cultures with the same language.

Comparison of WPPSI-IV and WISC-V cognitive profiles in 6-7-year-old Finland-Swedish children - findings from the FinSwed study.

The Wechsler scales are among the most widely used tests in cognitive and neuropsychological assessments. When assessing children aged 6:0-7:7 years the clinician can choose between Wechsler Preschool and Primary Scale of Intelligence - Fourth Edition (WPPSI-IV) and Wechsler Intelligence Scale for Children - Fifth Edition (WISC-V). Information about how the tests function and differ in this overlapping age range is limited. Using a between-subjects design, the present study compared the cognitive profiles of typically developing Swedish-speaking children in Finland in this overlapping age range (6:1 - 7:2 years), assessed with the Swedish versions of either WPPSI-IV (n = 38) or WISC-V (n = 24). Profile analyses and one-way ANCOVA were performed to investigate differences in the comparable subtests, indexes and Full Scale IQ. On the subtest level, children assessed with WISC-V had significantly lower scores on the subtests Vocabulary, Matrix Reasoning, and Bug/Symbol Search compared to children assessed with WPPSI-IV. On the index level, scores for the Verbal Comprehension Index and the Fluid Reasoning Index were significantly lower for children assessed with WISC-V. The Full Scale IQ was significantly lower on WISC-V. Taken together, the findings indicate that WPPSI-IV and WISC-V produce partly different cognitive profiles. These differences are important to recognize when choosing which test to use and when interpreting the results of clinical assessments of children in this age group.
