In this study, frequency and importance level of perceived social support types from fifth through eighth graders were investigated to find out if they are significant differences according to social support sources. The study was carried out with the survey model. The sample consists of 2148 students (1068 girls, 1080 boys) attending fifth through eighth grades from 19 elementary schools in Istanbul. Child and Adolescent Social Support Scale (CASSS) was used to collect data. The data was analyzed with Anova for Repeated Measures. It was found that students' perceived frequency and importance level of social support types differed significantly according to the sources (parents, teachers, classmates, close friends, other people in school) of support (p<.05). This finding showed that students prefer different support types according to characteristics (emotional relationship, attitude, role, status) of the source.
