Learning Objective 1: Identify the utility of the Inventory of Functional Status-Fathers IFS-F for the assessment of the functional status of first-time fathers in the postpartum period.

Learning Objective 2: Understand the importance of assess functional status of the fathers to promote an adequate transition to parenthood and correct plan care at Health Centers.


 The aim of this study was to validate the Inventory of Functional Status-Fathers (IFS-F) to the Portuguese version, showing its reliability and validity, adapted to first-time fathers in the postpartum period.


The Inventory of Functional Status-Fathers (IFS-F) was developed by Tulman, Fawcett and Weiss (1993) to evaluate the functional status of fathers in postpartum. For the development of the Portuguese version of IFS-F, we followed two directives: (a) the linguistic and cultural adaptation to Portuguese language and (b) the psychometric study of this version, comparing it with the original. The IFS-F was applied, after the approval of the ethic committee, to a consecutive non probabilistic sample of 204 first-time fathers from a Health Centre (inclusion criteria: read and write, pregnancy, delivery and postpartum of the partner without complications, childbirth of a term new born), allowing with this sample the global psychometric study of the instrument.


The results of the psychometric study done with the Portuguese version tend to show that is an equivalent version to the original version. The test-retest confiable of the inventory has a high temporal stability. The internal consistency of remaining dimensionsare reasonable. Overall, apart from social and community activities dimension, where there is a marked difference compared to the value observed by Tulman, Fawcett and Weiss (1993), all other dimensions showed internal consistency similar to those found by the authors.


Regarding the implications for care practice and research: it is thought that this instrument demonstrated the importance of evaluated the functional status of fathers during their transition to parenthood and as so it demonstrated its utility as a guidance to health professionals to evaluated and to promote a healthy involvement of fathers during pregnancy, childbirth and postpartum of their partners, emphasizing the autonomy of fathers in the transition to parenthood.
