This study examined predictors of, and associations between, self-concept, demographic variables, and clinical measures in fifty-eight children and adolescents with Persistent Tic Disorder (PTD; 44 males, M_age = 11.9 years, SD = 2.74). Participants completed measures that assessed self-concept, tic severity, tic-related impairment, and comorbid psychological symptoms. Results showed that generalized anxiety disorder, major depressive disorder, persistent depressive disorder, total tic severity, number and complexity of tics, and total and social tic-related impairment were associated with self-concept. Tic-related social impairment mediated the relationship between tic severity and self-concept. Exploratory analyses found that total tic severity, motor tic severity, and vocal tic severity, as well as the number, intensity, and interference of tics predicted social tic-related impairment. Results suggest that treatments to reduce the number and complexity of tics, with additional focus on navigating social interactions, may serve to decrease tic severity and impairment, and in turn, improve self-concept.

本研究检查了 58 名患有持续性抽动障碍 (PTD；44 名男性，M_年龄 = 11.9 岁，SD  = 2.74) 的儿童和青少年的自我概念、人口统计学变量和临床测量的预测因素和之间的关联。参与者完成了评估自我概念、抽动严重程度、抽动相关障碍和共病心理症状的测量。结果显示，广泛性焦虑症、重度抑郁症、持续性抑郁症、抽动的总严重程度、抽动的数量和复杂性以及抽动相关的总和社交障碍与自我概念相关。抽动相关的社交障碍调节抽动严重程度和自我概念之间的关系。探索性分析发现，总抽动严重程度、运动抽动严重程度和发声抽动严重程度，以及抽动的数量、强度和干扰可预测与抽动相关的社交障碍。结果表明，减少抽动次数和复杂性的治疗，并额外关注社交互动，可能有助于降低抽动的严重程度和损害，进而改善自我概念。
