Abstract
BACKGROUND: Lederman designed the prenatal self-evaluation questionnaire, which is a widely used tool for evaluating the psychological well-being and health perception of women during pregnancy. However, its structure and reliability may vary according to the population and cultural context in which it is applied. In Peru, no exhaustive studies have been conducted to validate the psychometric properties of this questionnaire. OBJECTIVE: Assess the psychometric properties of Lederman-designed prenatal self-evaluation questionnaire in a sample of Peruvian women using the network approach (BootEGA). METHODS: An instrumental investigation was conducted involving 790 women whose ages ranged from 18 to 45 years (M = 23.87, SD = 6.76). The network approach was used to analyze the data and evaluate the structure of the questionnaire. RESULTS: The results obtained revealed the presence of a network structure consisting of five dimensions. These dimensions showed stability levels (0.70) and optimal average loads (0.15), supporting the idea that Lederman designed the prenatal self-evaluation questionnaire be composed of five different dimensions. Furthermore, structural consistency showed that the questionnaire is accurate and stable, with estimates <0.99. CONCLUSION: Using the network method, the psychometric robustness of the Lederman-designed prenatal self-evaluation questionnaire was satisfactorily validated in the sample of Peruvian women. These findings reinforce the questionnaire's relevance as a reliable tool for assessing psychological well-being during pregnancy, providing valuable insights for maternal health professionals.
