Use of Rasch person-item maps to validate a theoretical model for measuring Attitudes toward Sexual Behaviors

Abstract: In general, the Attitudes toward Sexual Behaviors (ASB) or Sexual Attitudes measures have not been focused in the conjoint measurement of persons and items in the same construct, and have not reflected the new sexual behaviors neither the context where sexual behaviors take place. The purpose of this study was to provide evidence of the validity of a theoretical model for the measurement of ASB using the person-item map provided by a Rasch model. The theoretical model explicitly defines the ASB construct and m… Show more

“…This map depicts a hierarchy between student abilities and item difficulty levels in HeTMAI on the same continuum [33]- [35]. The Wright map is divided into two areas: left and right [41]. The left area represents the location of the person's abilities, and the right shows the item's difficulty level.…”

“…The validity test used an item analysis and distribution of people (Blanc & Rojas, 2018), where the numbers 47 and 10 were the most difficult and easiest questions, respectively. In this case, the two items should not be included in the test series, due to having poor distinguishing power.…”

“…Overall, 80% of test item difficulty level is relatively parallel with the measured constructs. By that, the test possesses good construct validity (Blanc & Rojas, 2018;Lu & Bi, 2016;Neumann et al, 2011).…”
