Abstract: Objective To explore the correlation between self-concept and subjective quality of life among children with tic disorders (TD). Methods The Piers-Harris Children's Self-concept Scale (PHCSS) and the Inventory of Subjective Life Quality (ISLQ) were completed by 65 children with TD and 71 normal children from March to September, 2015; and analyzed with single factor analysis, correlation analysis and multi factors regression analysis. Results There was no significant difference in PHCSS scores between the TD children with and normal ones (t<1.624, P>0.05). The ISLQ scores of school life, self-awareness and cognitive component were less in the TD children than in the normal ones (t>2.051, P<0.05). The PHCSS subscores correlated with ISLQ subscores (P<0.05), except the following: PHCSS scores of behavior did not correlate with ISLQ scores of peer relationship, school life, living environment, self-awareness and cognitive component; PHCSS scores of intelligence and school environment did not correlate with ISLQ scores of family life, peer interaction and the living environment; PHCSS scores of physical appearance and properties did not correlate with ISLQ scores of family life and living environment; PHCSS scores of anxiety did not correlate with ISLQ scores of family life, peer interaction and cognitive component; PHCSS scores of affiliation did not correlate with ISLQ scores of peer interaction; and PHCSS total score did not correlate with ISLQ scores of family life and living environment. PHCSS scores of affiliation were the factor related with the quality of life (β=0.301, P<0.05). Conclusion The quality of life may be impaired in the children with TD, which may associate with the self-concept and need further intervention.
