The inventory of functional status-Antepartum period. Development and testing

The Inventory of Functional Status-Antepartum Period (IFSAP) includes six subscales measuring the extent to which a pregnant woman continues her usual household, social and community, childcare, personal care, occupational, and educational activities. Content validity was established at 94.4%. Reliability testing used a sample of 192 pregnant women. Internal consistency reliability using average correlations for the subscale item to subscale total scores ranged from .57 to .87. Subscale to total IFSAP score correlations ranged from .53 to .90. Test-retest reliability used a subsample of 21 pregnant women. The coefficients ranged from .27 to .93. Initial construct validity testing was accomplished by examination of subscale correlations, by comparing IFSAP scores for pregnant women who had no children with those who had children, and by comparing women who had complications and/or restrictions with women who experienced no complications or restrictions. The IFSAP may be used in research and clinical practice to assess functional status during pregnancy.
