Exploration of the Multidimensionality of the Attitude Towards Disabled Persons Form-O Using Both Exploratory and Confirmatory Bifactor Modeling

Student responses to the 20-item ATDP Form-O were utilized to conduct an exploratory bifactor analysis (EBFA) with a bi-quartimin rotation. The established exploratory structure was then tested using confirmatory bifactor analysis (CBFA). Multiple exploratory models were tested including previously established factor structures, before applying the EBFA as a CBFA.
