The reliability and factor structure of the index of spouse abuse with African-American women.
This study investigated the reliability and validity of the Index of Spouse Abuse (ISA) when used with a sample of 504 African-American women. The initial factor validity analysis for the ISA (Hudson & McIntosh, 1981) resulted in two subscales: a physical abuse scale (ISA-P) and a nonphysical abuse scale (ISA-NP). Factor analysis with this sample of African-American women revealed three factors instead of two. Coefficient alpha estimates of reliability were over .90 for the original ISA subscales and with the African-American sample. The discussion compares and contrasts the factor structure observed with the sample of African-American with the factor structure reported in the original validation studies. The study demonstrates the need to critically evaluate the extent to which instruments developed to measure spouse or partner abuse are valid and reliable when used with diverse groups that may not have been represented in the samples used for initial instrument development and validation work.
