Behavior disorders and personality in children with tic disorders / 中国组织工程研究

ABSTRACT

BACKGROUND:Psychological disorder and behavior disorders can affect the development of behavior and personality in children.OBJECTIVE:To investigate the behavior disorders and the personality in children with tic disorders (TD).DESIGN:A comparative investigation between TD children and the healthy controls.SETTING:It was conducted at the Department of Pediatrics,Daqing Oil Felid General Hospital in Heilongjiang ProvincePARTICIPANTS:Totally 110 outpatients including 92 males and 18females, diagnosed as TD at the Department of Pediatrics, Daqing Oil Felid General Hospital,were selected (TD group) from February 2003 to December 2004.According to the clinical manifestations,they were divided into transient tic disorder group (46 cases),chronic motor/vocal tic disorder group (34 cases) and Tourette Syndrom (TS) group(30 cases).All the patients were newly diagnosed without any medication and intracranial organic diseases. Meanwhile,30 children with normal physical examination findings, between the ages of 7 and 14,24 males and 6 females, were selected as controls. Informed consents were obtained from guardians of all the participants.used to measure the children's social skills and behaviors (It contains a 113-item behavior problems scale. According to the children's ages,the items were classified into 9 factors,including somatic complains,poor social skills,compulsions,undisciplined,hyperactivity,Asperger syndrome,immaturity,hostility and aggressiveness.The scores of referring items constitute the total score of each factor).Comparison of these scores between patients and healthy controls is helpful to determine if a factor in affected children is abnormal. The closer the relationship between the patients and the controls is, the less behavioral problems Personality Questionnaire (EPQ) was adopted in this study to evaluate the personality in the patients compared to healthy controls.{There were four major dimensions of personality including introversion/extraversion,neuroticism,psychoticism and validity questionnaire (construct validity).When the validity score was over 70,it represented that the EPQ was invalid.An over-61.5 neuroticism score represented an apparent neuroticism tendency. Once the neuroticism score and introversion/extraversion score were over 56.7,mental instability or instable tendency could be suspected. When introversion/extraversion score was over 56.7and the neuroticism (extraversion) score was less than 43.3,it represented a sanguine personality or such tendency. When both of the neuroticism score and introversion/extraversion score were less than43.3 (introversion),it revealed a phlegmatic personality or such tendency. And when the introversion/extraversion score was less than43.3 with neuroticism score over 56.7,it represented a melancholic personality or such tendency.}MAIN OUTCOME MEASURES:Comparison of Achenbach's CBCLand EPQ between patients and healthy controls .RESULTS:Totally 110 TD patients and 30 healthy children completed the control group (t=3.12-8.60, P ＜ 0.01).The hyperactivity score in the transient tic group was significantly higher than that in the control group (t=2.01, P ＜ 0.05). In the chronic motor tic disorder group and the TS group,the scores of depression/anxiety,poor social skills,compulsions,social withdrawal,hyperactivity and aggression were all higher than those in the control group(t=2.11-7.65, P ＜ 0.05-0.01).In all of these three TD groups, score factors relating to social functions,such as movements, social skills and school life were apparently lower than those in the control group (t= 1.97-7.31, P ＜ 0.05-0.01).(t=2.76-4.32, P ＜ 0.05-0.01), while the score of validity questionnaire was lower than that in control group (t=3.49-6.38, P ＜ 0.05).CONCLUSION:It reveals that TD patients have many behavioral problems,personality defects and poor social skills. Of all the TD groups,the transient tic group has a higher occurrence rate of disease and only one abnormal factor, hyperactivity. While,the chronic motor tic disorder group and the TS group have more abnormal behavioral factors.
