The Symptom Checklist-90-Revised is a 90-item multidimensional self-report symptom measure that assesses current symptoms of psychopathology and psychological distress. The items were scored on a 5-point Likert scale ranging from 0 (not at all) to 4 (extremely). It assesses nine symptom dimensions (somatization, obsessive compulsive, interpersonal sensitivity, depression, anxiety, hostility, phobic anxiety, paranoid ideation, psychoticism). Global measures are provided to summarize overall distress, and these include the Global Severity Index, Positive Symptom Distress Index, and Positive Symptom Total. Raw scores are calculated by dividing the sum of scores for a specific dimension by the number of items in the dimension. Global severity index is calculated by summing the scores of the nine dimensions and additional items, then dividing by the total number of responses. Total score ranges from 0 to 360. Higher scores indicate worsening of disease.
