title: Psychometric Properties of an Adapted Version of the U.S. Household Food Security Survey Module for Assessing Food Insecurity Among Low-Income Pregnant Latinas.
abstract: This study examined the internal validity of an adapted version of the U.S. Household Food Security Survey Module administered to a sample of 241 pregnant Latinas. Single-parameter logistic (Rasch) measurement model was used to assess the psychometric properties of the adapted module. Two of 14 questions examined did not fit within the acceptable range (0.70-1.30). The severity level of 12 of the 14 questions was similar across two time periods, before pregnancy and the past month of pregnancy. These findings suggest the adapted module is valid for use among pregnant Latinas, yet some items might not be applicable during pregnancy.
