WAIS scores for a non-clinical British sample
The British Journal of Clinical Psychology
|February 1, 1987
Summary
British adults scored an average Full Scale Intelligence Quotient of 116.5 on the Wechsler Adult Intelligence Scale (WAIS). This study compared these results to American norms, suggesting a need for further research.
Area of Science:
- Psychometrics
- Cognitive Psychology
- Human Intelligence
Background:
- The Wechsler Adult Intelligence Scale (WAIS) is a widely used measure of adult intelligence.
- Establishing population-specific norms is crucial for accurate intelligence assessment.
- Previous WAIS research has primarily focused on American populations.
Purpose of the Study:
- To administer the WAIS to a British sample.
- To compare the obtained intelligence quotient (IQ) scores with established American WAIS norms.
- To assess the need for culturally adapted or population-specific WAIS norms in the UK.
Main Methods:
- The Wechsler Adult Intelligence Scale (WAIS) was administered to 63 healthy British volunteers.
- Full Scale Intelligence Quotient (FSIQ) scores were calculated.
- Statistical analysis was performed to determine the mean and standard deviation.
Main Results:
- The British sample achieved a mean FSIQ of 116.5 (SD = 9.7).
- This mean FSIQ is notably higher than the standardized American WAIS mean of 100.
- The obtained standard deviation was comparable to American norms.
Conclusions:
- The British sample demonstrated a higher average IQ compared to American WAIS norms.
- These findings suggest potential cultural or normative differences in intelligence test performance.
- Further research is recommended to validate these results and explore the implications for WAIS interpretation in the UK.
