I am investigating a discrepancy between male and female self reports of sexual experiences. The original survey consists of a female version (asking about victimization) and a male version (asking about perpetration). Typically, when given the original version, female's reported rates of victimization are about 2/3s higher than male rates of perpetration.
I have modified the original survey (both male and female versions) in order to determine whether the wording of the modified version will have an impact on the female/victim--male/perpetrator discrepancy. One of my hypotheses is that the modified version will produce a narrower discrepancy between female reports of victimization, and male reports of perpetration.
I need to figure out what test (or series of tests) I can use to determine if there is a significant difference between the discrepancy rate of original survey, and the discrepancy rate of my modified version.
- males and females are not matched, and I have different sample sizes of males and females
- each subject was administered both versions (original and modified) of the survey, according to gender
- subjects answered the original survey first, and then were given the modified survey
- my data will be nominal -- e.g. "Yes" I've had this experience, or "no" I haven't had this experience.
