Screening for adjustment disorders and major depression in otolaryngology patients using the Hospital Anxiety and Depression Scale.

The authors conducted a study to demonstrate the prevalence of psychiatric symptoms among 100 otolaryngology inpatients (50 with non-malignant conditions; 50 with malignancies), and to investigate the efficacy of the Hospital Anxiety and Depression Scale (HADS) as a screening test for psychiatric disorders in otolaryngology. A structured interview was conducted according to the Adjustment Disorders and Major Depressive Episodes section of DSM-N, which demonstrated that 30% of the inpatients with benign diseases met the criteria for some psychiatric disorders (one patient for major depression and 14 for adjustment disorders) and that 46% of the inpatients with malignancies met the criteria (nine patients for major depression and 14 for adjustment disorders). There were highly significant differences between the HADS scores of the patients with psychiatric disorders and those without. Comparing the sensitivity and the specificity using the HADS as a screening test, the optimal cut-off point was 12, which produced 92% sensitivity, 90% specificity and 85% positive predictive value (PPV) among not only non-malignant and malignant cases taken together but also among malignant cases only.
