Question 1

Can the DASS-21 differentiate between anxiety and depression?

Accepted Answer

The DASS-21 was designed to discriminate between depression, anxiety, and stress as distinct constructs. Confirmatory factor analyses generally support a three-factor structure, though moderate intercorrelation exists. Clinically, it provides useful differentiation but should not be used as a sole diagnostic tool for distinguishing anxiety from depressive disorders.

Question 2

Why must DASS-21 scores be multiplied by 2?

Accepted Answer

The DASS-21 is the short form of the 42-item DASS. To ensure comparability with full DASS-42 severity cutoffs and published norms, each subscale raw score must be multiplied by 2. Omitting this multiplication results in underestimation of symptom severity.

Question 3

What are the DASS-21 severity cutoffs for each subscale?

Accepted Answer

After multiplying by 2: Depression -- Normal 0-9, Mild 10-13, Moderate 14-20, Severe 21-27, Extremely Severe 28+. Anxiety -- Normal 0-7, Mild 8-9, Moderate 10-14, Severe 15-19, Extremely Severe 20+. Stress -- Normal 0-14, Mild 15-18, Moderate 19-25, Severe 26-33, Extremely Severe 34+ (Lovibond & Lovibond, 1995).

Question 4

Is the DASS-21 a diagnostic tool or a screening measure?

Accepted Answer

The DASS-21 is a dimensional measure of emotional distress, not a diagnostic tool. The severity labels describe where a person falls in the population distribution, not whether they meet DSM criteria. Clinical diagnosis requires a structured diagnostic interview.
