Because the use of multi-item measures to assess childhood sexual abuse (CSA) retrospectively is relatively new and remains limited, little analysis has been conducted of these measures overall. The purpose of this study was to evaluate and compare the psychometric qualities of three multi-item CSA measures representative of three approaches to measuring CSA severity found in the literature. Two samples consisting of women who experienced CSA were used, recruited from a family practice clinic (N = 132) and from the community (N = 19). Indicators for each measure came from a self-administered instrument developed for a larger study. One measure was identified as a scale (the CSA Frequency Scale), the other two as indexes (the CSA Count Index and the CSA Multiple Characteristics Index). The scale measurement model was used to evaluate the scale, while the less familiar index measurement model was used to evaluate the two indexes. The results demonstrated that none of the three multi-item CSA measures was superior to the others, although they all met most of the criteria set a priori for satisfactory quality. Across the measures, test-retest reliability ranged from .92 to .94; correlations with the criterion variables ranged from r = .36 to .41. For the CSA Frequency Scale, Cronbach's alpha was .90, and construct (factorial) validity was supported. For the two indexes, these procedures were not indicated, but in their stead the data obtained from content and indicator specification, indicator collinearity diagnostics, and external validity procedures yielded generally satisfactory results. These results are an encouragement for further development of multi-item measures that use these three approaches. Standardized CSA scales and indexes are needed not only for research on the health outcomes of CSA, but also for nursing practice to help quantify the severity of CSA that clients experienced, describe practices, and explain outcomes.
