BackgroundThere is a lack of health-related quality of life (HRQOL) questionnaires to evaluate pediatric musculoskeletal diseases in Brazil. The Pediatric Outcome Data Collection Instrument (PODCI) is widely used elsewhere for pediatric patients with musculoskeletal disorders, but it has not been fully validated in Brazil. Validation of the PODCI in the Brazilian Portuguese language is important to improve the assessment of pediatric patients with musculoskeletal diseases and to compare Brazilian study results with results from the international literature. This study aimed to analyze the test–re-test reliability and the convergent validity indicators for the quality of life scores obtained by application of the PODCI to children and adolescents with juvenile idiopathic arthritis (JIA).MethodsThe PODCI underwent translation, transcultural adaptation, and field testing. Fifty-seven children and adolescents with JIA were administered the PODCI questionnaire. The Child Health Questionnaire - Parent Form 28 (CHQ PF-28) was used as the gold standard. Pain scales were employed, clinical examinations were performed, and laboratory inflammatory activity tests were conducted.ResultsThe three versions of the PODCI exhibited good internal consistency (Cronbach’s alpha coefficient >0.70), good reproducibility (p < 0.05), and good correlation compared with the gold standard (CHQ), as shown by a Spearman coefficient (Rho) >0.40 (p < 0.05).ConclusionsThe PODCI was validated in patients with JIA in Brazil. This questionnaire was found to be valid, precise, and reliable. It can be successfully applied in research conducted by healthcare professionals who work with children and adolescents with musculoskeletal system disorders.

Introduction Being a soccer player is one of the dreams most present in the popular imagination of Brazilian children. However, the path to professionalization is arduous and several reasons can be pointed out for this difficulty: a very competitive environment, few chances, and poor career counseling, among others. In competitive soccer, the athlete must be ready for all the demands that will be made, as well as accept the demand for the best possible performance. Furthermore, athletes from the youth system are still adolescents and youths in development, usually up to 21 years of age, who are often forced to choose soccer and its demands, at the expense of their studies and family lives, to become professional players. In this scenario, a still little-debated topic is mental health among soccer players. Objectives To verify the frequency of anxiety and depression symptoms among soccer players of the under-20 youth categories of Pernambuco clubs and to assess its association with sociodemographic, athletic, and health data. Methods The Hospital Anxiety and Depression Scale (HADS) was applied and socio-demographic, athletic, and health data were collected. A marginal descriptive analysis was conducted, as well as categorical and numerical assessments of anxiety- and depression-related variables. Finally, a linear regression study of the anxiety and depression scores was conducted. Results A statistically significant association was found between income received and an increase in anxiety symptoms. An increase in depressive symptoms as income decreased was also identified. Conclusion Further research with larger numbers of participants is needed, as well as with a greater variety of clubs, to better understand the relationship observed. Level of Evidence II; Prognostic study – Investigation of the effect of a patient characteristic on the outcome of their illness.
