In this study, it is aimed to examine to what extent individuals' responsibility attitudes and perceived social support from their family predict and effect their social anxiety. Participants of the study consist of 681 students enrolled in education faculties of Eskisehir Osmangazi, Anadolu and Usak Universities in 2012-2013 school year. Participants were administered Interaction and Audience Anxiousness Scale (Leary, 1983) to determine social anxiety levels, Responsibility Attitude Scale (Salkovslcis et. al, 2000) for responsibility attitude levels, and Perceived Social Support from Family Scale (Procidano & Heler, 1983) to identify the social support they receive from their families. Data of the study were analyzed through Pearson moment correlation, multiple linear regressions, and path analyzes techniques. Results of the study manifested that participants' responsibility attitudes and perceived social support from family predicted social anxiety at significant level. Results also indicated that participants' responsibility attitudes had significant impact on social anxiety both directly and over social support they receive from their families. Social support has direct effect on social anxiety as well.
