A validation study was conducted on the Child Sex Abuse Attitude Scale (CSAAS) using confirmatory factor analysis (CFA) to examine the factor structure of three comparative CFA models. Multitrait multimethod analysis was also used to examine the convergent and discriminant validity of the CSAAS. The instrument was developed based on the theory of attitude development of L. Festinger (1957). This resulted in a four-factor first-order structure of cognition, value, affect, and behavior, and a single-factor second-order structure representing attitude. A national sample of 215 school psychologists responded to a survey consisting of 3 measurement instruments. The instruments included the CSAAS; the California Personality Inventory (CPI) subscales for intellectual efficiency, tolerance, and well-being; and a demographic survey. CFA results supported the higher-order factor structure of the CSAAS with minor modifications. On examination of the CSAAS subscales and the CPI subscales, convergent validity was found to be statistically significant for two of the CSAAS subscales, although the practical significance of the association was low.
