The ineffectiveness of the Hospital Anxiety and Depression Scale for diagnosis in an Omani traumatic brain injured population.

Background: The rehabilitation of the traumatic brain injury (TBI) patient is especially challenging in non-western populations as the phenotypic indicators as well as the neurobehavioral assessments for the survivors of brain injury are limited.Objective: The study screened for the prevalence of anxiety and depressive states among patients with TBI and examined the validity of the Hospital Anxiety and Depression Scale (HADS) to identify TBI patients with comorbid affective dysfunctions, specifically anxiety and depressive disorders, in an Omani population.Methods: Sixty-eight survivors of TBI were screened with the semi-structured, Composite International Diagnostic Interview (CIDI) and the HADS. A receiver operating characteristics (ROC) curve was calculated to discriminate the power of the HADS for every possible threshold score.Results: The semi-structured interview revealed the prevalence rate of 57.4% for depressive disorder and 50% for anxiety disorder. The sensitivity (53.8%) and specificity 75.9%...
