This study was carried out to compare resilience, loneliness, and academic self-efficacy of male students studying at day and boarding high schools of Baneh in academic year 2014-2015. The participants were selected through multistage cluster sampling method. To do so, from among all of the high schools of Baneh, one day high school and one boarding high school were randomly selected. Then, a total number of 200 students (100 for each high school) were selected at random. In the next step, Connor-Davidson Resilience Scale (2003), UCLA Loneliness Scale (Russell, Peplau & Cutrona, 1980), and the Academic Self-Efficacy Questionnaire (McIlroy & Bunting, 2002) were administered to the participants. The obtained data were analyzed through descriptive (mean and standard deviation) and inferential statistics (independent t-test). The results showed significant differences between the two groups. More specifically, the day high school students had higher levels of resilience and academic self-efficacy. On the contrary, they had a lower level of loneliness compared to their counterparts in boarding high schools.
