Test diagnostic quality criteria

Criterion validity

The criterion validity of the German version of the PHQ-D panic module was determined on a total of 528 patients (357 general medical patients and 171 psychosomatic patients) and with reference to the "Structured Clinical Interview for DSM-IV (SKID-I)" as the "gold standard" The sensitivity of the questionnaire for the diagnosis of panic disorder is 73% (specificity = 92%) in psychosomatic patients and 73% (specificity = 98%) in medical patients and thus has very good classification properties.

Standard values

In a study by Rief et al., Normal values for the short form of the PHQ-D panic module were examined on a representative sample of the population (N = 2066). 6.2% of the population sample said they had had at least one panic attack in the last 4 weeks. 69% said they had had a panic attack before., 58% of the population samples said that the seizures were completely unexpected, 60% reported that they found these seizures severely debilitating or that they were afraid of one and finally, 55% of the population sample studied reported having physical symptoms of a panic attack.
