The problem examined in the proposed study was the underutilization of the intranet portals (IP) by faculty in institutions of higher education (IHE). Despite the time and investment allocated to the IP, the technology remains underutilized to improve productivity, efficiency, and justify its investment yet there is lack of understanding of why faculty accept or reject the technology. The purpose of this quantitative correlational study was to determine if the five-factor model (FFM) (agreeableness, conscientiousness, extraversion, neuroticism, and openness) could be used to predict faculty behavioral intention (BI) to accept or reject IP. Understanding individual differences that influence faculty behavior to reject IP enables IHE administrators to develop intervention programs to increase acceptance of the technology. This study was designed to answer five research questions on the influence of FFM on BI towards IP by testing five null hypotheses for each personality factor using structural equation modeling (SEM). A sample with 272 usable responses was collected from a population of 526 faculty at six universities. The results showed that agreeableness personality trait influenced behavioral intention when mediated through perceived ease of use (PEOU) (r[272] = -0.21, p = 0.005) and that extraversion personality trait influenced behavioral intention mediating through PEOU (r[272] = 0.22, p = 0.002). The results did not show evidence of influence on behavioral intention when mediating through PEOU for conscientiousness (r[272] = 0.04, p = 0.543), neuroticism (r[272] = 0.11, p = 0.091), openness (r[272] = 0.13, p = 0.098). Furthermore, the results did not show evidence of influence on behavioral intention mediating through perceived usefulness (PU) for agreeableness (r[272] = -0.03, p =0 .636), conscientiousness (r[272] =0.07, p = 0.267), extraversion (r[272] = 0.06, p = 0.376), neuroticism (r[272] = -0.08, p = 0.140), and openness (r[272] = -0.03, p = 0.606). IHE administrators can use the findings to improve user-friendliness of IP and involve faculty with agreeableness and extraversion personality traits as champions in the technology acceptance efforts. Future studies can include additional personality factors, different populations, and institutional factors to better understand the role of personality factors in technology acceptance.
