Just World Beliefs among Medical Students and the General Public in Hawai'i

Just World Beliefs (JWBs) are a psychological tendency to conclude the world is an inherently fair place in which people experience the outcomes they deserve. Strong JWBs positively correlate with a personal commitment to long-term ambitions and blaming people for their negative health outcomes. This study aimed to measure JWBs in medical students and the general population of Hawai'i. It was hypothesized that (1) medical students would have stronger JWBs than the general public, and (2) JWBs would be strongest for medical students in the latter part of their training. Current residents of Hawai'i and medical students at the University of Hawai'i at Mānoa were recruited to complete a web-based survey measuring JWBs using the Global Belief in a Just World Scale. A t-test was used to compare JWB strength between the groups. A regression analysis identified factors predicting strength of JWBs. Contrary to both hypotheses, medical students in Hawai'i possessed weaker JWBs than Hawai'i residents (P<.01), and JWBs did not differ based on training duration (P=.97). Age (P<.01) was the only demographic variable to significantly predict JWBs. The difference in JWBs among medical and non-medical cohorts was no longer significant after controlling for age. Among medical students, younger age was associated with weaker JWBs. Future studies should explore the prevalence and effects of JWBs among diverse populations and the medical professionals that care for them.
