Which instrument has no Australian norms?

• A. GAF
• B. STAI
• C. ORS
• D. WHODAS

Answer: (B)

Scores from a psychological instrument are most useful when there are normative reference values for the population you’re working with. Australian norms let you say whether a person’s score is high, low, or typical for Australians. If there aren’t Australian norms, you lose that direct comparison and interpretation becomes less precise for that country. The State-Trait Anxiety Inventory is a widely used measure, but the widely cited normative data come from American and other international samples rather than a clearly established Australian standard. In contrast, the other instruments listed have more commonly available Australian normative data, so clinicians in Australia can interpret their scores against local reference groups. Therefore, this instrument is the one that lacks Australian norms, making it the best choice for the question.
