The Renfrew Word Finding Scale: application to the South African context

Area of Science:

• Speech and Language Pathology
• Developmental Psychology
• Cross-cultural Psychology

Background:

• The Renfrew Word Finding Scale is a standardized tool for assessing expressive vocabulary.
• Assessing expressive vocabulary in diverse linguistic and cultural groups requires culturally appropriate instruments.
• Previous research has highlighted potential cross-cultural variations in language assessment tools.

Purpose of the Study:

• To evaluate the suitability of the Renfrew Word Finding Scale for Indian and White Durban English-speaking children.
• To compare the performance of these children to established British norms.
• To identify potential lexical or item-related challenges within the scale for these populations.

Main Methods:

• Administered the Renfrew Word Finding Scale to 30 Indian (Group A) and 30 White (Group B) children aged 8-9 years.
• Statistically compared mean raw scores and mean mental ages to British norms.
• Conducted item analyses to examine group-specific lexical characteristics and item difficulties.

Main Results:

• Both Indian and White Durban English-speaking children performed significantly below British norms.
• Indian children (Group A) scored significantly lower than White children (Group B).
• Item analyses revealed specific difficulties, suggesting lexical or cultural influences.

Conclusions:

• The Renfrew Word Finding Scale, in its current form, is not suitable for assessing expressive vocabulary in Indian and White Durban English-speaking children.
• The findings suggest a need for cultural adaptation or revision of the scale for use with these populations.
• Further research is warranted to explore linguistic and cultural factors influencing performance on expressive vocabulary assessments.
