Somatization, anxiety and depression as measures of health-related quality of life of children/adolescents with cancer.

This descriptive study of health-related quality of life of children with cancer compared children/adolescents', parents' and teachers' ratings for somatization, depression and anxiety to determine if there were significant correlations among respondent scores. In addition, the percentage of agreement among respondents and significant differences based on age, gender, use of cranial radiation and treatment status were measured. Forty-three children/adolescents with cancer, currently receiving therapy for at least 1 year or who had completed therapy for no more than 3 years (excluding children who had received bone marrow transplants or who had brain tumors), were recruited, with a parent and teacher, from 3 university medical centers. The Behavioral Assessment System for Children questionnaires for children/adolescents, parents and teachers were used. Parents reported a higher level of depression for the children/adolescents with cancer than did the teachers or the children/adolescents themselves. Parents reported a higher level of anxiety for the children/adolescents than did the teachers. High positive correlations were found among scores from parents and teachers and among scores from parents and children/adolescents for the anxiety and depression but not somatization subscales. Children/adolescents and teachers had high, positively correlated scores only for the depression subscale. High, positive correlations were found between somatization, anxiety and depression within each group of respondents. A significant percentage of agreement between all respondents on ratings for at-risk status was obtained only for the depression subscale. Age was the only variable found to have an influence on scores and only for the anxiety subscale. Copyright 1999 Wiley-Liss, Inc.
