RESUMO
INTRODUCTION:: The Personal Experience Screening Questionnaire (PESQ) is an instrument devised for assessing the magnitude of drug misuse among adolescents. However, its psychometric properties have not been evaluated in adolescent samples outside the United States. OBJECTIVE:: To assess the internal reliability and validity of the Brazilian version of the PESQ. METHOD:: A cross-sectional study was carried out with 84 adolescents from a clinical sample and a community-based sample. All of them answered the PESQ. RESULTS:: Among adolescents from the community, the PESQ problem severity index, which can vary from 18 to 72, was 26.48±9.28, whereas the clinical sample scored 42.89±10.02 (p<0.001). Cronbach's alpha was 0.91. Factor analysis resulted in a four-factor solution. Furthermore, both samples also had different mean scores for the other distinct content areas measured by the instrument. CONCLUSION:: Evidence to support the reliability and validity of the Brazilian version of the Personal Experience Questionnaire was found.

Resumo Introdução: o Personal Experience Screening Questionnaire (PESQ) é um instrumento destinado ao rastreamento de problemas relacionados ao uso de drogas entre adolescentes. Entretanto, suas propriedades psicométricas não foram avaliadas em populações de adolescentes de outros países além dos Estados Unidos. Objetivo: avaliar a confiabilidade e a validade da versão brasileira do PESQ. Método: foi feito um estudo transversal envolvendo 84 adolescentes de uma amostra clínica e de uma amostra não clínica. Todos responderam ao PESQ. Resultados: entre os adolescentes da população geral, o índice de severidade de problema da PESQ, que pode variar de 18 a 72, foi de 26,48±9,28. Por outro lado, a população clínica teve pontuação de 42,89±10,02 (p<0,001). O alfa de Cronbach foi de 0,91. A análise fatorial resultou em uma solução de quatro fatores. Além disso, ambas as populações apresentaram pontuações significativamente diferentes em outras subescalas do PESQ. Conclusão: as evidências sustentam a validade e a confiabilidade da versão brasileira do PESQ.
