To compare the clinical features of children, adolescents and adults with obsessive-compulsive disorder (OCD), understand the clinical characteristics of children and adolescents with obsessive-compulsive disorder were further understood.

Ninety cases of obsessive-compulsive disorder were selected in accordance with the diagnostic criteria of obsessive-compulsive disorder in the fifth edition of the American psychiatric disorder diagnosis and Statistics Manual (DSM-V), including 45 patients aged 7 to 17 years old (juvenile group), a total of 45 patients aged 18 to 45 years old were enrolled(adult group). The Yale-Brown obsessive compulsive scale (Y-BOCS), Eysenck personality checklist(EPQ), symptoms checklist 90 (SCL-90) was used to compare their disease performance, personality characteristics and comorbid mental symptoms characteristic.

①In the form of OCD, the compulsive behavior of juvenile group was higher than that of the adult group (t=1.143, P<0.05). ② In the characteristics of psychiatric symptoms associated with adolescent, interpersonal sensitivity, hostility, the three factor scores of the juvenile group were higher than those of the adult group (t=1.414, 2.189, 2.425, P<0.05) ③In the personality characteristics, the juvenile group got higher score in mental dimension, neurotic dimension and coverability dimension than the adult group, but internal and external dimension were lower than those of the adult group. However, the overall score of each dimension had no significant differences between the two groups (P>0.05).

The compulsive behavior is the main clinical manifestation in juvenile obsessive-compulsive disorder. Their psychology is more sensitive, hostile, and emotionally unstable. The clinicians should be more likely to intervene in the early stages of their psychological and behavioral interventions.
