This study examines the effect of social support on children who attend the Care of Schoolchildren after school hours (CSAS) program, and the level of the state of concern of their parents. Thirty-four parents and twenty-five their children (age: 7.4±0.9) completed the questionnaires. The results of this study showed children participants who had friends in the CSAS center scored significantly higher in the recognition of social support (RSS) than those who did not. Additionally, children participants who felt their advisors communicated with them scored higher in the RSS with their CSAS advisor than those who did not. The results also showed that children participation in the CSAS center lowered parent’s feelings of concern and uneasy feelings. Furthermore, the results showed the level of the state of concern in the parent group who answered that their children had good friends in the CSAS center, significantly lower than that in the non-group. Finally, the results demonstrated the parent group who answered that their children changed had significantly higher their change on the feelings and satisfaction than those who did not.In conclusion, the results of this study indicate that both children and their parents who utilized the CSAS program felt to be supported from friends and the CSAS center advisor as sources of social support.
