Background The Lederman Prenatal Self-Evaluation Questionnaire (PSEQ) is used to assess psychosocial adaptation to pregnancy, labor, childbirth, and maternity. The PSEQ is a tool used in various countries and has been translated into Portuguese; however, it needs to be validated in Brazil. This study aimed to analyze the validity and reliability of the PSEQ in Brazilian pregnant women. Method This methodological validity study investigated internal consistency and reliability using Cronbach’s alpha and intraclass correlation coefficients. Construct validity was assessed using Pearson’s correlation between domains and confirmatory factor analysis. To assess concurrent validity, Pearson’s correlation between the different domains of the PSEQ and Prenatal Psychosocial Profile-Portuguese Version (PPP-VP) was determined. The level of significance was set at 5%. Results This study included 399 pregnant women in the northeastern region of Brazil. The internal consistency and reliability of the total PSEQ score were high (Cronbach's alpha = 0.89; intraclass correlation coefficient = 0.95). Validity analysis showed positive and significant correlations between all PSEQ domains, ranging from 0.14 to 0.56. Confirmatory factor analysis demonstrated the following values of goodness of fit: RMSEA = 0.05, SRMR = 0.08, CFI = 0.61, χ2/df = 1.77. The discriminant and concurrent validities of the PSEQ were confirmed. Conclusions The Portuguese version of the PSEQ has adequate psychometric properties and is a valid and reliable tool to evaluate psychosocial adaptation to pregnancy in Brazilian pregnant women.

Desconfortos musculoesqueléticos são observados em praticamente todas as mulheres grávidas. O fi sioterapeuta, por meio do curso para gestantes (CG), talvez contribua para proporcionar uma melhora na qualidade de vida (QV). O objetivo dessa pesquisa é avaliar a infl uência de um CG na QV dessas mulheres. Foi realizada uma pesquisa quase-experimental, com gestantes (n = 44) agrupadas, de acordo com a participação (n = 24), ou não (n = 20) em um CG. Abordaram-se atividades educacionais e orientações de exercícios indicados para a gestação, o momento do parto e o puerpério. Analisou-se a QV das gestantes, através do Medical Outcomes Study (MOS) 36-item short-form health survey (SF-36). O Teste dos Sinais avaliou a diferença intragrupo e a comparação dos resultados intergrupos foi realizada pelo Teste U de Mann-Whitney. A signifi cância estatística foi de 5% (p < 0,05). Houve diminuição significante da capacidade funcional no grupo experimental (GE) (p = 0,03) e no grupo controle (GC) (p = 0,03) e também aumento da saúde mental no GE (p = 0,04). A análise intergrupos da avaliação final apresentou uma diferença signifi cante em três domínios do SF-36: saúde geral (p = 0,02), capacidade funcional (p = 0,01) e vitalidade (p = 0,009), com menor QV no GC. O CG representou uma alternativa efi caz para a promoção de saúde materna, intervindo diretamente na QV.Palavras-chave: gravidez, modalidades de fi sioterapia, qualidade de vida.

Background: The Lederman Prenatal Self-Evaluation Questionnaire (PSEQ) is used to assess psychosocial adaptation to pregnancy, labor, childbirth, and maternity. The PSEQ is a tool used in various countries and has been translated into Portuguese; however, it needs to be validated in Brazil. This study aimed to analyze the validity and reliability of the PSEQ for Brazilian pregnant women. Method: This methodological validity study investigated the internal consistency and reliability using Cronbach’s alpha and intraclass correlation coefficient, respectively. Construct validity was assessed using Pearson’s correlation between the domains and confirmatory factor analysis. To assess the concurrent validity, the Pearson’s correlation between the PSEQ and Prenatal Psychosocial Profile-Portuguese Version (PPP-VP) was determined. Results: This study included 399 pregnant women from the northeastern region of Brazil. The internal consistency and reliability of the total PSEQ score were high (Cronbach's alpha = 0.89; intraclass correlation coefficient = 0.95).

Confirmation factor analysis demonstrated the following values of goodness of fit: RMSEA = 0.05, SRMR = 0.08, CFI = 0.61, x²/df = 1.77. The discriminant and concurrent validities of the PSEQ were confirmed. The level of significance was set at 5%. Conclusions: The Portuguese version of the PSEQ has adequate psychometric properties and is a valid and reliable tool to evaluate the psychosocial adaptation to pregnancy in Brazilian pregnant women.
