The primary purpose of this study was to investigate unidimensionality of scale used to understand student's behavior towards an Online Discussion Site (ODS). The extended Technology Acceptance Model (TAM) model was adapted and examined for unidimensionality using Rasch analysis. Seven factors was used to model the student's intention to use ODS. There are Online Course Design (OCD), User-interface Design (UID), Previous Online Learning Experience (POLE), Perceived Usefulness (PU), Perceived Ease of Use (PEOU), Perceived Interaction (PI) and Intention to Use an Online Discussion Site (IUODS). Item fit statistics and principle component analysis (PCA) suggested that unidimensionality assessment can be achieved after removal of one item from User-interface Design (UID) factor. Our result reports that after removal the misfitting item, the 23 item instrument might provide a unidimensionality assessment of student's intention to use ODS ability. © 2013 Springer International Publishing.
