The primary purpose of this study was to determine the extent to which the data collected on ARRT certified radiographers utilizing digital imaging equipment support the modified TAM2 theoretical model in a radiology department where the equipment use is mandated. This study measured model fit using SEM as well as examining a series of dependence relationships between observed exogenous and endogenous variables.
The study population consisted of 120 radiographers certified by the American Registry of Radiologic Technologists (ARRT) utilizing direct capture digital radiographic units in The Ohio State University Medical Center Healthcare System. A survey method was used to investigate the applicability of the modified TAM2 utilizing a written questionnaire adapted from previous Technology Acceptance Model (TAM) and Technology Acceptance Model 2 (TAM2) studies. The response rate was 92.5%.
The results of this study indicate the data does support the implied theoretical model; however age and gender were shown to have little impact on the original model. Standardized regression coefficients (β) were used to examine a series of dependence relationships between observed exogenous and endogenous variables. Two relationships were identified in this study in reference to the intention to use digital imaging equipment in a mandated healthcare environment. A relationship was recognized involving voluntariness and subjective norm and concerning subjective norm and the intention to use the digital imaging equipment. These findings support previous research indicating that the social context in which the technology is employed plays an important role in an individual's decision to ultimately use the technologic innovation.
