The aim of the study is to find out the effects of the “Resilience Program for Preschool Children” (RPPC) on 5-year-old children’s social skills. The RPPC was adapted from Building Resilience in Preschool Children written by Baum & Anchor in 2005. “Social Skills Evaluation Scale (SSES)” developed by Avcıoğlu (2007), and “Personal Information Form” (PIF) developed by the researcher were employed as data collection tools. These tools were applied to 67 children 5 years of age in total at second semester of 2014-2015 academic year, which comprises of 18 children who take education at Marmara University Prof. Dr.Ayla Oktay Preschool Education Unit; 23 children who take education at Goztepe Semiha Sakir Social Services and Child Protection Institution(SSCPI) Kindergarten; and 26 children who take education at Münevver Şefik Fergar Primary School Kindergarten. Pre-test and post-test experimantal control group was used, in order to investigate the effect of “The RPPC” on the dimensions of social skills. Findings show that the experimental group children who took special training sessions received meaningfully higher scores than the control group children who did not undergo any special education, and social skills of the experimental group children are developped more than the control group children’s (p>0,05).
