APPS-S: A Tool for Measuring the Attitudes Toward Prostitution and Women in Prostitution in the Spanish Population.

ABSTRACT

This study was designed with the purpose of testing the psychometric properties of the Spanish version of the Attitudes toward Prostitution and Prostitutes Scale through three studies with different samples. The first one explores the test's dimensional structure or constructs validity through confirmatory factor analysis, as well as internal consistency and test-retest reliability. The second one focuses on discriminant and criteria validity. Finally, the third one examines the scale's convergent validity and its sensitivity to detecting changes. The results support two subscales with an optimal index of internal consistency, structural stability over time, and discriminative power between groups of participants. It is, therefore, an adequate tool for adults as well as young people and teenagers, and for detecting changes in the context of intervention or awareness workshops.
