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.
本研究调查了配偶虐待指数（ISA）在504名非裔美国女性样本中的信度和效度。对ISA（Hudson & McIntosh，1981）进行的初始因素效度分析得出了两个分量表：身体虐待量表（ISA-P）和非身体虐待量表（ISA-NP）。对该非裔美国女性样本进行的因素分析显示出三个因素，而非两个。原始ISA分量表以及非裔美国样本的信度系数α估计值均超过0.90。讨论部分比较并对比了非裔美国样本所观察到的因素结构与原始效度研究报告中的因素结构。该研究表明，对于为测量配偶或伴侣虐待而开发的工具，在用于初始工具开发和效度验证工作的样本中可能未被代表的不同群体时，有必要严格评估其效度和信度。
