Psychometric properties of the toddler feeding style questionnaire in fathers and its gender invariance.

Parental feeding practices and behaviours are closely related to a number of child outcomes, including eating behaviour and health. The Toddler Feeding Style Questionnaire (TFSQ) was developed to provide an accurate instrument for evaluating parental feeding practices for toddlers by assessing two dimensions: responsiveness and demandingness. As the initial validation study was conducted in a sample of mothers only, the aims of this study are: a) to validate the TFSQ in fathers, b) to analyse its measurement invariance as a function of gender and parenting experience and c) to explore associations between socio-demographic variables and both dimensions. The TFSQ was completed by 377 fathers and 583 mothers. CFA confirmed the two-factor structure within the same items as the initial validation study, with good model fit indices (X = 230.089; TLI = 0.883; CFI = 0.91; RMSEA = 0.08 (90% CI 0.068-0.092), SRMR = 0.070). Strict invariance measurement in terms of gender and parenting experience was achieved. Overall, fathers scored higher than mothers on demandingness, regardless of their parenting experience. Primiparous mothers scored higher than multiparous mothers and primiparous fathers on the responsiveness dimension. However, there were no gender-based differences on this dimension for parents with more than one child. These results confirm that the TFSQ is an adequate and validated instrument for assessing parenting dimensions, as it performs equally well for mothers and fathers, regardless of their parenting experience. There is also support for the notion that parental attitudes to feeding may be related to their socio-economic background.
