Adjustment problems are the most common problems among first-year students who are going through an active adjustment phase when they join the University. The objective is to assess the prevalence of adjustment problems and identify associated factors among first-year undergraduate students in Addis Ababa University 6kilo campus, Addis Ababa, Ethiopia, 2024 GC. An institution-based cross-sectional study design was conducted, and a sytematic random sampling technique was employed. Data was collected by using a data collection tool and the SACQ assessment model. Data processing and analysis were done by using Statistical Package for Social Sciences (SPSS) Version 26, then the data were presented in frequency tables and charts. One hundred ninety-nine (64.8%) participants had overall adjustment problems. Among the study participants, a considerable variety of respondents, 142 (46.3%) and 143 (46.6%) respondents had personal-emotional problems and institutional adjustment problems, respectively. Similarly, 134 (43.6%) and 141 (45.9%) had academic adjustment and social adjustment problems, respectively. Variables with an important association with overall adjustment problems were sex, parental marital status, and monthly pocket money.
