RESUMEN
Resumen

Objetivo:

analizar la validez de la estructura factorial para un cuestionario adaptado a partir del Preschooler Feeding Questionnaire (PFQ) con subescalas asociadas al control y la presión parental al comer.

Metodología:

se elaboró un cuestionario de 11 reactivos expresados con escalas tipo Likert y agrupados en dos subescalas Presión Maternal al Comer y Control Maternal al Comer. Se evaluaron 50 madres y posteriormente se realizó un análisis factorial para identificar la estructura factorial subyacente, mediante la evaluación de la confiabilidad con el α de Cronbach, la extracción de componentes principales con una rotación Varimax y la normalización de Kaiser. Luego, se efectuó un análisis confirmatorio de factores con 430 madres. Por medio de la estadística descriptiva se estudiaron las prácticas parentales de «control» y «presión», mientras un modelo SEM valoró la existencia de relaciones causales entre el IMC, el género infantil y dichas prácticas.

Resultados:

se validó una estructura factorial de dos escalas, Control y Presión, compuestas cada una de tres reactivos (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 se estableció relación causal alguna entre estos factores con el IMC o el género de los infantes, siendo ambos factores mayores a la media.

Conclusión:

la adaptación del formulario constituye una herramienta válida y fiable de futura utilidad en el estudio de prácticas nutricionales parentales.
ABSTRACT
Abstract

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.
