This study investigated the relationship between residence hall climate and students' adjustment to their collegiate environment. The questionnaire was administered via the web to first-year students living in coeducational residence halls at a public university in the southeastern United States. The residence hall climate was examined in two major categories: social climate and physical climate. The adjustment measures included overall, academic, social, personal-emotional adjustment, and institutional attachment. The results revealed that group cohesiveness in residence halls was significantly related to students' college adjustment. In addition, high degrees of personalization in a residence hall room and less disruption by noise were significantly related to students' attachment to their institutions. Practical applications of these findings are discussed and future research areas are identified. (Contains 4 tables.)
