Evaluated the validity, stability, and clinical utility of the Pediatric Pain Questionnaire (PPQ), a comprehensive, multidimensional instrument for assessing childhood pain. Previous studies demonstrated adequate psychometric properties of the PPQ using small samples. Results of the current study, using a large sample (N = 100) of children and adolescents with chronic pain associated with rheumatic disease, were consistent with initial validation studies. ⋯ Significant correlations also were found between pain ratings and measures of disease activity and functional status. VAS ratings evidenced moderate stability over a 6-month period in this sample of youth with relatively stable disease activity. Other components of the PPQ provide comprehensive information that is clinically useful for treatment planning and evaluation.
