Objective: Aim of this study was to examine the diagnostic value of standardized questionnaires evaluating for anxiety and depression before brain surgery.
Methods: From a prospective observational study of patients undergoing brain surgery in 2016, patients were randomly selected and a structured clinical interview for DSM (SKID) as well as a battery of standardized questioners evaluating for mental comorbidities was performed. The presence or absence of psychiatric disorder symptoms was correlated the gold standard the SKID.
Results: 59 patients were examined. 64% were female. Mean age was 52 years. 39% of patients were diagnosed with depression in the SKID interview but only 20% of patients had pathological ADS-scores (0.038). Concordant positive results were seen in 10 cases only. 42% of patients were diagnosed with an anxiety disorder in the SKID interview and 37% of patients had pathological STAI-T and STAI-S scores (p=0.064). Concordant positive results were seen in 19 cases.
Conclusion: Standardized questionnaires were capable to distinguish for real anxiety but underestimated the rate of depression as detected by the SKID interview.
