Resumo

Dada a prevalência dos transtornos mentais e sintomas psicológicos elevados, houve um apelo à ação para ampliar os serviços de saúde. A detecção precoce dos sintomas e a avaliação do estado psicológico são fundamentais para oferecer cuidados ideais. As medidas de autorrelato têm ampla utilidade para avaliar diagnósticos específicos e explorar sintomas psicológicos. O objetivo deste estudo foi gerar novas evidências psicométricas da adaptação argentina da versão curta do Inventário de Sintomas Psicológicos. Por meio de amostragem não probabilística e intencional, foram selecionados 760 indivíduos de 18 a 63 anos (M = 28,1; DP = 8,61). Por meio de análises fatoriais confirmatórias, constatou-se que o modelo de nove fatores correlacionados apresentou melhor ajuste e foram encontradas evidências sobre sua invariância escalar, métrica e configuracional segundo gênero e região. Os fatores apresentaram majoritariamente valores de confiabilidade adequados, condizentes com pesquisas anteriores. São fornecidos escores normativos T. Os resultados mostraram que o instrumento é válido e confiável, podendo ser uma ferramenta valiosa em vários contextos, particularmente na atenção primária, onde a avaliação requer tempos muito curtos e informações úteis.
