Abstract: | ABSTRACTThe literature on campus climate has mainly focused on diversity and demographic variables within single or multiple university campuses from one country. There is a need to investigate campus climate further with regard to cultural issues and the role of teachers. This study thus proposed to examine perceived teacher support as a mediator of the relation between institutional and psychosocial variables of the campus climate of two universities from two culturally distinct countries. To achieve this goal, 980 Brazilian and Portuguese university students answered the Institutional and Psychosocial Campus Climate Inventory. Findings showed significant differences in how students from two different countries described their campus climate and how both Brazilian and Portuguese students described their institutional climate more accurately than their psychosocial climate. Moreover, results from a mediation analysis revealed that perceived teacher support mediated the relationship between students’ perceptions of the institutional readiness of their university and their sense of well-being, as well as newcomer adjustment. A moderation analysis showed that the country of origin moderated the relationship between students’ perceived teacher support and newcomer adjustment. Implications for developing a positive campus climate are discussed. |
