Patient Health Questionnaire-9 in Spinal Cord Injury: An Examination of Factor Structure as Related to Gender

摘要

Background/Objective:Despite the attention depression after spinal cord injury (SCI) has received, research and clinical practice have been hampered by inadequate emphasis on reliable and valid measurement. Assessment of symptoms in persons with SCI is challenged by the presence of “transdiagnostic” symptoms and unexamined effects of gender. The objective of this study was to examine the factor structure of the Patient Health Questionnaire-9 (PHQ-9; the 9-item depression scale of the Patient Health Questionnaire) and determine whether the structure replicates across gender.
