To what extent does the anxiety scale of the Four-Dimensional Symptom Questionnaire (4DSQ) detect specific types of anxiety disorder in primary care? A psychometric study

Table 7 Likelihoods and likelihood ratios associated with low (0–3), moderate (4–9) and high (10–24) 4DSQ anxiety scores with respect to panic disorder, agoraphobia and social phobia, and to any anxiety disorder respectively

^aLH = likelihood of anxiety score within the Anxiety disorder group and No anxiety disorder group respectively.
^bLR = likelihood ratio.
