Abstract
Background: Musculoskeletal pain in children and adolescents is prevalent and responsible for high levels of disability. Instruments to measure the presence and impact of pain in this population are needed.
Objective: To translate, cross-culturally adapt, then test the measurement properties (structural validity, reliability and construct validity) of a questionnaire (Presence and Impact of Pain in Kids (PIP-Kids) questionnaire) to measure the presence and impact of pain in children and adolescents.
Design: Measurement properties study.
Methods: We conducted a measurement properties study. We translated and culturally adapted the PIP-Kids questionnaire into Brazilian Portuguese. The structural validity was measured by Confirmatory Factor Analysis. Reliability was measured by Kappa Coefficient. Measurement error was measured by the percentage of agreement. Construct validity was measured by Spearman Correlation.
Results/findings: We included 656 children and adolescents from public and private schools. During the translation and cross-cultural adaptation no changes to wording were necessary. Structural validity confirmed two domains. Reliability by Kappa Coefficient ranges from 0.20 to 0.68. Measurement error by the percentage of agreement ranged from 60.2 to 92%. Construct validity was confirmed with 80.5% in accordance with prior hypotheses.
Conclusion: The PIP-Kids questionnaire translation and cross-cultural adaptation were adequate. The PIP-Kids questionnaire also has adequate structural validity with two dimensions (presence and impact), fair reliability, good agreement, and adequate construct validity.
