Self-concept and introversion in adolescents with cleft lip and palate.

The purpose of this study was to investigate if adolescents with cleft lip, or palate, or both (CLP), have an altered self-concept, and to assess their degree of introversion, compared with a control group. The CLP group consisted of 55 adolescents (aged 17-20 years) and the control group consisted of 31 adolescents (16-19 years). The Tennessee Self Concept Scale (TSCS) was used to measure the subjects' self-concept, while the Eysenck Personality Questionnaire Inventory (EPQ-I) was used to measure introversion. The results indicate that those with CLP have a normal or even a high self-concept, and no signs of introversion.
