Early and effective interventions in the area of mental health of children and adolescents are of unquestionable importance. Thus, there is a great need to develop reliable tools to monitor the success or failure of these interventions. The goal of this study is to investigate the psychometric properties of the Brazilian Portuguese Youth Outcome Questionnaire 2.01, an instrument that seeks to evaluate the process and outcome of psychotherapy with children and adolescents from the perspective of the parents or legal guardians. After a cross-cultural adaptation, confirmatory and exploratory factor analysis and a network analysis were performed. The sample consisted of 341 parents or legal guardians of children (172) and adolescents (163) from 1 to 19 years old; 51% of the youths were male. It was observed that confirmatory factorial analysis based on the original model did not present good fit indexes, but the exploratory factorial analysis performed yielded a two-factor model which showed good fit indexes. Evaluating the expected influence among the nodes that composed the network analysis, items were identified that seem to activate symptom networks. The conclusion was that there is evidence of validity for the Brazilian Portuguese Youth Outcome Questionnaire 2.01, which can be used by Brazilian psychotherapists to plan treatments and monitor psychotherapeutic results.
