سودآوری بالینی پرسشنامه سلامت بیمار -9 در ارزیابی افسردگی شدید بعد از ضایعه مغزی تروماتیک

The PHQ-9 has adequate clinical utility as a screening instrument for depression in outpatients with traumatic brain injury. Elevations on this instrument cannot, however, be automatically attributed to neuropathology, especially not in the context of premorbid psychiatric dysfunction. Clinicians should conduct more thorough follow-up assessment in those with highly elevated PHQ-9 scores.
