Values-based behavior is a highly studied concept but difficult to assess within the Acceptance and Commitment Therapy’s framework. For this reason, the present study sought to psychometrically adapt the P-VQ in a sample of 368 adults. Validity evidence based on test content (analysis of representativeness of each item) and based on the relationship with other variables (concurrent, divergent, and incremental validity) were satisfactorily obtained. Exploratory Structural Equation Modeling analyses supported evidence in favor of a two- dimensional latent structure with a better fit compared to previous Confirmatory Factor Analysis proposals. Reliability analysis (Alpha and Omega) demonstrated robust internal consistency of the scale. Measurement invariance (configural, metric, and scalar) regarding gender was obtained as evidence of equity. In conclusion, the P-VQ demonstrated excellent psychometric properties for validity, reliability, and fairness.
O comportamento baseado em valores é um conceito altamente estudado e apresenta avaliação de dificuldade dentro da estrutura da Terapia de Aceitação e Compromisso. Como resultado, o presente estudo buscou adaptar psicometricamente o P-VQ em uma amostra de 368 adultos, por se tratar de uma proposta preliminar. As evidências de validade baseadas no conteúdo do teste (análise da representatividade de cada item) e na relação com outras variáveis (validade concorrente, divergente e incremental) foram obtidas de forma satisfatória. Análises de Modelagem de Equações Estruturais Exploratórias apoiaram evidências em favor de uma estrutura latente bidimensional com melhor ajuste em relação às propostas anteriores de Análise Fatorial Confirmatória. A análise de confiabilidade (Alfa e Ômega) demonstrou graus significativos de consistência interna. A invariância da medida (configuracional, métrica, escalar e estrita) em relação ao gênero foi obtida como evidência de equidade. Em conclusão, o P-VQ demonstrou excelentes propriedades psicométricas em relação à validade, confiabilidade e justiça.

Reliability analysis (Alpha and Omega) demonstrated significant degrees of internal consistency. The invariance of the measurement (configurational, metric, scalar, and strict) regarding gender was obtained as evidence of equity. In conclusion, P-VQ demonstrated excellent psychometric properties with respect to validity, reliability, and fairness.
