Interpretive risks: the use of the Hopkins Symptom Checklist 90-Revised (SCL 90-R) with brain tumour patients

Abstract

Patients with brain tumours often report distress. Interpretive problems ensue when measures normed on healthy persons are utilized to quantify distress. This study investigated potentially spurious elevations on the Hopkins Symptom Checklist 90 Revised (SCL 90-R). Responses of 17 patients were obtained prior to aggressive chemotherapy. Traditional interpretation indicated that 47% of the patients endorsed clinical levels of somatization, 53% obsessive-compulsive and 59% psychotic disorders. Elevations were attributable to common consequences of brain tumours, medication and the emotional reaction to prognosis. Conventional interpretation would lead to inappropriate classifications. The majority of SCL 90-R item endorsements were significantly different than those of the norm group. Appropriate interpretation of scores is discussed.
