CHACON VILLALOBOS, Alejandro. Confirmatory analysis of a control and pressure when eating questionnaire among mothers of Costa Rican preschoolers. PSM [online]. 2021, vol.19, n.1, pp.133-157. ISSN 1659-0201.  http://dx.doi.org/10.15517/psm.v19i2.45885.

Objective: to analyze the validity of the factorial structure for a questionnaire adapted from the Preschooler Feeding Questionnaire (PFQ) with subscales associated with control and parental pressure when eating. Methodology: a questionnaire was prepared with 11 items expressed with “Likert” type scales and grouped into two subscales: “maternal pressure when eating” and “maternal control when eating”. This was evaluated with 50 mothers, subsequently carrying out a factor analysis to identify the underlying factorial structure, evaluating the reliability with Cronbachs α and using a principal components extraction with a Varimax rotation and Kaiser normalization. A confirmatory factor analysis was subsequently performed with 430 mothers. Descriptive statistics studied both “control” and “pressure” parental practices, while an SEM model assessed the existence of causal relationships between BMI, child gender and these practices. Results: a factorial structure of two scales was validated, “Control” and “Pressure”, each composed of three items (x2 = 187.3, df. = 116, x2 / df. = 1.62, CFI = 0.998, GFI = 0.991, AGFI = 0.983, NFI = 0.994, IFI = 0.998, and RMSEA = 0.018). No causal relationship was established between these factors with the BMI or the gender of the infants, both factors being greater than the average. Conclusion: The adaptation of the questionnaire is a valid and reliable tool of future utility in the study of parental nutritional practices.
