The Reliability and Validity of Diagnostic Interview Schedule for Children Version IV-Korean Version (DISC-IV)

OBJECTIVES: The aim of this study was to evaluate the reliability and validity of the Korean Version of the Diagnostic Interview Schedule for Children Version IV(DISC-IV), a highly structured diagnostic interview used to assess more than 30 psychiatric disorders in children and adolescents. METHODS: A total of 91 study subjects, including 67 subjects who visited the child and adolescent psychiatry outpatient clinic at our institution and 24 community-based subjects, were assessed using the Korean Version of the DISCIV. Clinical diagnosis was used as a gold standard for the examination of the validity of the DISC-IV. Forty-four of the study subjects were randomly selected for test-retest reliability measurement. RESULTS: The validity of the Korean Version of the DISC-IV showed kappa values ranging from 0.25 to 0.40 in the clinical sample and 0.65 to 1.00 in the community sample. The sensitivities varied according to the diagnostic categories, but the specificities were excellent for all diagnostic entities. CONCLUSION: The Korean Version of the DISC-IV showed good reliability and validity in Korean children and adolescents. The Korean Version of the DISC-IV might be a useful tool for assessing psychiatric disorders in children and adolescents.

Effects of Risperidone on the Schedule-Induced Polydipsia in Rats / 신경정신의학

OBJECTIVES: This study was designed to evaluate the effects of risperidone on the schedule-induced polydipsia (SIP) which is one of animal model of obsessive-compulsive disorder in rats. We administered risperidone as a serotonin and dopamine blocking agent, fluoxetine as a selective serotonin reuptake inhibitor, and haloperidol as a dopamine antagonist to rats which showed schedule-induced polydipsic behaviour. METHODS: Sprage-Dawley rats weighing 200 - 250gm were individually housed and main-tained and allowed free access to water. The rats were placed on a restricted diet. To induce polydipsia, rats were placed in the cage where a pellet dispenser automatically dispensed 90mg pellets on a fixed-time 60 seconds (FT 60s) feeding schedule over 150 minute test session per day. Water was available at all times in the cage. After 4 weeks of daily exposure to the FT 60s feeding schedule, experimental rats met a predetermined criterion for polydipsic behavior (greater than 3 times of water per session on average). 5 groups of rats were administered risperidone (0.1mg/kg, i.p), risperidone (0.5mg/kg, i.p), fluoxetine (5mg/kg, i.p.), haloperidol (0.1mg/kg, i.p.), and vehicle (1cc/kg, i.p. ) for 3 weeks. The rats were tested once a week to access schedule induced polydipsic behavior. Water bottles were weighed before and after the 150-minute test session. The chronic effects of administration of experimental drugs on schedule induced polydipsic behavior were analyzed with ANOVA and Scheffe test as a posthoc comparison. In order to measure water consumption in non-polydipsic food-deprived rats, a separate group of rats (N=8) was individually housed and given a single bolus (14.5gm) of food per day which maintained them at their average body weight. RESULTS: The results were as follows; 1) After 4 weeks of scheduled feeding procedure, the experimental group showed significant differences than the bolus control in the amount of water consumption as compared with their average water intakes for 4 weeks. At the same periods, there were no differences between the experimental group and the bolus control in the body weight. 2) The fluoxetine group showed significant decrease in the amount of water intake at 1st, 2nd, and 3rd weeks of drug treatment as compared with their average amount of polydipsic water intakes. The risperidone 0.1mg group and the risperidone 0.5mg group showed significant decrease in the amount of water intake at the 3rd weeks of drug treatment as compared with their baseline of polydipsic water intakes. However, the haloperidol group and the vehicle control group showed no changes of amounts of water intake for 3 weeks of treatment as compared with their baseline of polydipsic water intakes. 3) The fluoxetine group (22.5+/-10.4ml) showed significantly lower amounts of water intake than haloperidol group (41.3+/-7.1ml) at 2nd weeks of drug treatment. And also the fluoxetine group (18.8+/-3.5ml) showed significantly lower amounts of water intake than the haloperidol group (35.0+/-11.7ml) and the vehicle control (34.4+/-6.8ml) at 3rd weeks of drug treatment. The risperidone 0.1mg group and the risperidone 0.5mg group showed significantly lower amounts of water intake than the haloperidol group (35.0+/-11.7ml) at 2nd weeks and the vehicle control (37.5+/-12.5 , 34.4+/-6.8ml) at 2nd and 3rd weeks of drug treatment. CONCLUSIONS: Above findings suggest that the fixed time feeding procedure for schedule induced polydipsia could be applied as an effective animal model of obsessive compulsive disorder for the evaluation of pharmacological challenge study. We confirmed that chronic treatment with risperidone revealed antipolydipsic effect as effective as fluoxetine on the schedule-induced polydipsic behaviour but the onset of effect was later than fluoxetine.

Development of the Korean Form of Yale Global Tic Severity Scale: A Validity and Reliability Study / 신경정신의학

OBJECTIVES: This study was carried out to develop the Korean form of Yale Global Tic Severity Scale(YGTSS)-family & clinical rating version. The severity of motor and phonic tics was rated according to five separate dimensions : number, frequency, intensity, complexity,and interference. METHODS: The Korean form of YGTSS was applied to 100 children who visited psychiatric outpatient clinic with chief complaints of tic symptom. Together with YGTSS, Clinical Global Impression for Tourette's syndrome(CGI-TS), Obsessive-Compulsive disorder(CGI-OCD), At tention-Deficit/Hyperactivity Disorder(CGI-ADHD) were administered to all subjects for examining convergent and discriminant validities. RESULTS: We could confirm high internal consistency, convergent and discriminant validities and interrater reliability of YGTSS by analysing data from 100 children with tic disorder. In factor analysis, items were clusterd to 2 factors which were identical motor and phonic tic subscales. CONCLUSION : The results of this study indicate that the Korean form of YGTSS is a reliable and valid rating scale for rating tic symptom severity. It can be used to evaluate tic symptom objectively and to quantify the tic severity in the studies for tic disorder.

Effects of the Clozapine on the Suppressed Spontaneous Alternation Behaviour in Rats / 신경정신의학

OBJECTIVES: The study was designed to evaluate the role of the 5-HT2 and dopanmine D2 antagonist on spontaneous alternation behaviour which is an animal model of obsessive compulsive disorder in rat. On the basis of serotonin-dopamine interaction hypothesis, the effect of clozapine was evaluated by applying the suppressed spontaneous alternation behaviour model. METHODS: The apparatus for spontaneous alternation behaviour was a black plexiglas T-maze with distinctive black and white goal boxes. Black guillotine doors separated the start box and the goal boxes from the main body of the T-maze. Small cups of chocolate milk were placed in the corners of both goal boxes. At 24 hours prior to experiment, rats(spraque-Dawley) were food-deprived. The food-deprived rate were put into T-maze, in which both goal during which it was placed in the start box and allowed to choose one of the goal boxes for each time. The mean number of choices until the occurrence of spontaneous altemation behaviour were checked. After baseline of the number of choices of spontaneous altemation behaviour was stabilized, the spontaneous altemation was disrupted by nonselective 5-HT agonist, 5-MeODMT(1.25mg/kg/IP). The experimental animals were stratified nito 5 groups : clomipramine(5mg/kg/IP), clozapine(10mg/kg/IP), clozapine(20mg/kg/IP), haloperidol(0.1mg/kg/IP), and saline(0.2cc/IP) control groups. They all went through 21 days fo treatment(intraperitoneal). The protective effects against the 5-McODMT-induced disruption of spontaneous alternation behaviour were evaluated on the next day of drug treatment in each group. RESULTS: 1) SAB was supressed by 5-McODMT injection. 2) After 21 days of the drug treatment, the clozapine and the clomipramine groups showed significant difference from the haloperidol and the saline control groups in the reversal of 5-McODMT-induced from the haloperidol and the saline control groups in the reversal of 5-MeODMT-induced suppression of spontaneous altermation behaviour. 3) The clozapine(20mg/kg/IP) group was superior to the clomipramine group in the protective effect of 5-MeODMT-induced suppression of spontaneous alternation behaviour. CONCLUSION: In clinical situation, the we think that atypical antipsychotic drugs those acting as serotonin and dopamine receptor antagonist with no extrapyramidal side effect can be beneficial to improve the symptoms of obsessive-compulsive disorder.

The Relationship between Depressive Tendency in Postpartum Women and Factors such as Infant Temperament, Parentiong Stress and Coping Style / 신경정신의학

OBJECTIVES: This Study examined the relationship of depressive tendency in postpartum women with psychosocial factors such as infant temperament, parental stress and coping style. METHODS: The subjects consisted of 105 postpartum women, each of whom had an infant aged 4 to 12 months. They were assessed on demographic variables and on measures of the depressive symptomatology, infant temperament, parental stress and the coping style using Beck Depression Inventory(BDI), the EAS temperamental survey, Parenting Stress Index(PSI), the Way of Coping Checklist(WCC). And then we assessed the relationship of depressive tendency in postpartum women with psychosocial factors. RESULTS: The results were as follows: 1) Depressive tendency in postpartum women had significant relationship with emotionality(r=.26 p<0.05) and activity(r=.22 p<0.05) of infant temperament. 2) Depressive tendency in postpartum women had significant relationship with parenting stress(r=.44 p<0.001). 3) Depressive tendency in postpartum women had no significant relationship with coping style. 4) Parental stress had significant relationship with emotionality(r=.49 p<0.001) but did not have any relationship with sociability and activity of infant temperament. Parenting stress had no significant relationship with coping style. CONCLUSION: These results suggest that depressive tendency in postpartum women correlated with emotionality and activity of infant temperament correlated with parenting stress but not correlated with coping style. Infant temperament and parenting stress to child rearing are more significantly correlated with depressive tendency in postpartum women than coping style of postpartum women.

Psychiatric Characteristics of the Patients with Myofascial Pain Syndrome / 신경정신의학

We investigated the possible association between depression, anxiety, severity of recent stress in patients with myofascial paul, with chronic myofacial pain syndrome. On the initial visit, 30 subjects completed the following psychometiic battery Beck Depression Inventory, Spielberger State-Trait Anxiety Inventory and Global Assessment of Recent Stress. As compared with the neurosis control group and the healthy control group, the results were as follows: 1) The myofascial paul group showed higher scores than the healthy controls but lower than the neurosis controls, in the Spielberger State-Trait Anxiety Inventory. 2) The myofascial pain group showed higher scores than the healthy controls but lower than the neurosis controls, in the total score of Beck Depression Inventory. 3) The myofascial pain group showed higher scores than the healthy controls but lower than the neurosis controls, in the score of Global Assessment of Recent Stress. 4) In the factor analysis of Beck Depression Inventory, the myofascial pain group showed significantly higher scores than the healthy controls but lower than the neurosis control in the somatic symptom subscale. However, there were no significant differences among the myofascial pain group and other control groups in the other subscales. These findings suggest that the myofacial pain group is more anxious and depressed and more preoccupied with their somatic symptoms due to their myofacial pain and more stressed in recent periods. The authors propose that the psychiatric management is helpful in intervening with the progression of myofacial pain.

A Study of Self-Engulfment in Schizophrenic Patients / 신경정신의학

OBJECTIVE: This study was conducted to identify demographic variables and illness related variables which may affect the severity of self-engulfment in the patients with schizophrenia. We also studied the relationship between self-engulfment and insight, and the relationship between self-engulfment and self-esteem. METHODS: Data on demographic variables and illness related variables for the subjects were gathered from hospital records and clinical interviews by the psychiatrists. Degree of insight far the subjects was assessed through clinical interviews by the psychiatrists. Degree of self-engulfment and self-esteem for the subject was assessed from the self-engulfment scale and the self-esteem state respectively. A total of 111 patients with schizophrenia were selected for statistical analysis. RESULTS: 1) The females exhibited significantly higher socres than the males on the self-engulfment scale . 2) There was no illness related variable, which exhibited a significant difference among subgroups on the self-engulfment scale. 3) There was no significant correlation between the self-engulfment stores and the insight scores . 4) There was a significantly inverse correlation between the self-engulfment scores and the self esteem scores. CONCLUSION: The results of this preliminary study suggest that self-engulfment may develop despite lack of insight, and that there was inverse relationship between self-engulfment and self-esteem in the patients with schizophrenia. It also suggests that females are more subject to self-engulfment than males. So, authors suggest that it is valuable to do further studies of self-engulfment in the patients with schizophrenia.
