The attitudes toward forcible date rape (FDR) scale: Development of a measurement model

Abstract

Using data from 341 female and 237 male college students that were collected previously (Fischer, G. J.,Archives of Sexual Behavior, 15, 457–466, 1986), several true score measurement models were used to describe the variance-covariance structure of a nine-item attitude toward a forcible date rape (FDR) scale. The congeneric true score model fit the data best, but not satisfactorily. By deleting “noncongeneric” items, a six-item, unweighted linear composite variable based on the congeneric true score model was shown to fit the data, and reliabilities and validities based on this model proved satisfactory for females, males, and the total sample. The factor structure of the model for females and for males was not equivalent, but the general patterns were similar. Suggestions for further research included a validation study of the six-item scale on an independent sample and a comparison of 5-and 7-point Likert response scales to see if the lack of model equivalence by gender could be due, in part, to more variability in attitudes toward forcible date rape in men than women.
