Abstract
Variations in gender related item response rates were explored using a locally adapted household food security scale in the Brazilian National Sampling Household Survey 2004 (PNAD; n=101,155). Rasch Modeling was used to evaluate infit and measurement values separately for adult and children items by gender of the respondent. Adult and child related items presented good fitness. Both female and male respondents presented similar measurement values for adult and children items. For most items, infit values were found to be within adequate range (0.8-1.2), being practically identical when comparing female and male responses. In addition, the frequency of affirmative response to each of the items followed the same pattern independently of the gender of the respondent. The results of this study support the validity of the proposed scale to measure household food insecurity in Brazil.
