The purpose of this study was to confirm that appearance satisfaction of adolescents of multicultural families affect the peer-intimacy mediated by the self-confidence and that the mediating effect of self-confidence appear differently depending on the level of optimism. This study collected the data on appearance satisfaction, self-confidence, and peer-intimacy from 208 adolescents of multicultural families and 336 adolescents of common families. The measurements included Body Esteem Scale(BES) for the appearance satisfaction, Self-Concept Test for the self-confidence, Reevaluation of Life Orientation Test(LOT-R) for the optimism, and The Modified Interpersonal Relationship Scale for the peer-intimacy.
Looking at the results, first, the mediating effect of self-confidence was sustained in the process that appearance satisfaction affects the peer intimacy both in multicultural families and common families. Also, the mediating effect of self-confidence is supported in the high optimism group, whereas it isn’t supported in the low optimism group in this process. This shows that the mediating effect of self-confidence is depended on optimism level.
Synthesizing the above results, this study showed that the appearance satisfaction indirectly affects the peer-intimacy through the self-confidence rather than directly . In the case of adolescents who have high optimism, the higher their appearance satisfaction becomes, the higher their self-confidence and the high self-confidence leads to the higher peer-intimacy. These results implied that intervention strategies to increase the self-confidence can be effective in actual consulting adolescents of multicultural families who have the low optimism in order to increase the peer-intimacy, and at this time, it is necessary to take into account the individual differences, such as optimism. Based on these findings, the implications for future research and consulting practice were discussed.
