Validity and Reliability of the Korean Version of the Hamilton Depression Rating Scale(K-HDRS) / 신경정신의학

OBJECTIVES: The reliability and validity of the Korean version of Hamilton Depression Rating Scale (K-HDRS) were examined in Korean patients depressive symptoms. METHODS: 33 inpatients and 70 outpatients diagnosed as major depressive disorder or depressive episode of bipolar I disorder according to the DSM-IV criteria were assessed with K-HDRS, Clinical Global Impression score(CGI), Beck Depression Inventory (BDI) and Montgomery-Aberg Depression Rating Scale (MADRS). RESULTS: Internal consistency (Cronhach's alpha coefficeint=0.76) and interrater reliability (r=0.94, p<0.001) were statistically significant. Principal axis factoring analysis revealed 4 factors that accounted for 50.4% of the total variance. The correlations of K-HDRS with CGI, BDI and MADRS were 0.84, 0.54, 0.58 respectively. CONCLUSION: These results showed that the K-HDRS could be a reliable and valid tool for the assessment of depressive Korean patients. The K-HDRS will be a useful tool for assessing depressive symptoms in Korea.

The Reliability and Validity of The Migraine-Specific Quality of Life Questionnaire for Korean Migraine Suffers

BACKGROUND: Recurrent, often unpredictable, migraine attacks significantly interfere with daily functioning and productivity of patients with migraine. Quality of life measurement represents an important tool for evaluating migraine therapy and judging the impact of headache either on individuals or on society. The objective of this study was to test the reliability and validity of the translated version of MSQoL (Migraine-Specific Quality of Life) in Korean migraine patients. METHODS: Participants, migraineurs from the Samsung Medical Center Migraine Clinic, were screened using the International Headache Society migraine criteria prior to enrollment through direct interview. This survey included the MSQoL, MIDAS (Migraine Disability assessment) and STAI (State-Trait Anxiety Inventory). RESULTS: Sixty-five migraineurs were recruited. For the MSQoL, Cronbach's alpha was 0.93. Frequency and number of accompanying symptoms were predictive of the MSQoL. The negative correlation between the MSQoL scores and the MIDAS score was seen (r=-0.585, p<0.01). Similarly a negative correlation between the MSQoL scores and duration of headache was also observed (r=-0.38, p<0.01). Although a significant negative correlation between the MSQoL and STAI scores was present (r=-0.47, p<0.01), correlation between the MIDAS and the STAI scores was not significant. CONCLUSIONS: The MSQoL is a reliable and valuable migraine-specific quantitative tool to assess the degree of quality of life in Korean migraineurs. It has a potential to provide valuable information on migraineur's disability and anxiety level. The MSQoL has acceptable psychometric properties and can be used to estimate long-term outcome of migraine therapy in Korean population.

The Study for Switching Methods to Olanzapine in Korean Schizophrenic Patients Treated with Other Antipsychotics(I): Comparison of Therapeutic Effecacy / 신경정신의학

OBJECTIVES: This randomized, multicenter, open-label, parallel clinical trial was carried to compare the therapeutic efficacy and the proportion of successful switch between 'direct switching method' and 'start-tapering switching method' when switching an antipsychotic to olanzapine. METHODS: This study included both inpatients and outpatients who fulfilled the criteria for schizophrenia as defined in the ICD-10 from 13 hospitals, and were in need to be appropriate for switching antipsychotics. Subjects were randomly assigned to one of the two switching methods. For 'direct switching method' group, previous antipsychotics were abruptly discontinued and 10mg of olanzapine was administered, whereas for 'start-tapering switching method' group, initially 10mg of olanzapine was administered and previous antipsychotics was gradually tapered for 2 weeks. Olanzapine was used for 6 weeks and the dose was adjusted within the range of 5-20mg. The therapeutic efficacy was measured with PANSS, BPRS, and CGI-Severity. A successful switching was defined as the completion of the 6 week trial without either worsening of the symptom(i.e. CGI-S score becomes worse twice consecutively) or the exacerbation of extrapyramidal symptoms(i.e. Simpson-Angus Scale scores becomes worse). RESULTS: 103 schizophrenic patients were participated in this study. There were no differences in baseline characteristics such as the demographic variables, the severity of symptoms, the history of previous antipsychotics treatments, the dosage of olanzapine used and the compliance between two groups. The proportion of successful switch was 71.1% for "direct switching method" and 82.2% for "start-tapering switching method", and there was no significant difference between the two switching methods. Also response rates to olanzapine based on total PANSS total scores were not different between the two groups(26.9% vs. 31.1%). At the time of completion of the trial, the scores of PANSS total, PANSS subscales, CGI-S and BPRS have significantly decreased after switching to olanzapine. But the changes of all scales measuring therapeutic efficacy in both endpoint and weekly analyses were not significantly different between the two switching methods. CONCLUSION: Although this study trial has many limitations and problems as an open clinical trial, the results may suggest that there were no significant differences between the two switching methods in the therapeutic efficacy. It was also found that the additional therapeutic benefits could be obtained by switching their antipsychotics to olanzapine.

The Study for Switching Methods to Olanzapine in Korean Schizophrenic Patients Treated with Other Antipsychotics(II): Comparison of Safety / 신경정신의학

OBJECTIVES: This multicenter clinical trial involving 13 hospital sites compared the safety of switching to olanzapine between 'direct switching method' and 'start-tapering switching method'. METHOD: This study included both inpatients and outpatients who fulfilled the criteria for schizophrenia as defined in the ICD-10, and were in need to be appropriate for switching antipsychotics. Subjects were randomly assigned to one of the two switching methods. For 'direct switching method' group, previous antipsychotics were abruptly discontinued and 10mg of olanzapine was administered, whereas for 'start-tapering switching method' group, initially 10mg of olanzapine was administered and previous antipsychotics was gradually tapered for 2 weeks. Olanzapine was used for 6 weeks and the dose was adjusted within the range of 5-20mg. The safety of switching to olanzapine was measured with vital signs including body weight, adverse events reported spontaneously, laboratory tests, and various scales such as Simpson-Angus Scale(SAS), Barnes Akathisia Rating Scale(BARS), Abnormal Involuntary Movement Scale(AIMS), and Liverpool University Neuroleptic Side Effect Rating Scale(LUNSERS). RESULTS: 103 patients were switched to olanzapine in this study. The comparison between two switching methods did not show any significant difference in the dosage of olanzapine used, the concomitant use of benzodiazepine, the rate and reasons of drop-out, the adverse events, vital signs, laboratory tests, and most scales for measuring side-effects. However, the decrease in AIMS scores was significantly lower in 'direct switching method' group, and the concomitant use of anticholinergics was comparatively greater in 'start-tapering switching method' group. At baseline, SAS and BARS scores were 3.5 and 1.8 points respectively, and more than 70% of the subjects showed hyperprolactinemia. After switching to olanzapine, SAS, BARS, and AIMS scores were significantly decreased and the proportion of the patients with hyperprolactinemia was also decreased to less than 30%. However significant weight gain after the treatment of olanzapine was observed regardless of switching method. CONCLUSION: This study may suggest that switching to olanzapine can be done with relatively high safety regardless of switching methods and olanzapine can significantly decrease some side-effects induced by other antipsychotics.

Posttraumatic Stress Disorder Prevalence, Symptoms, Depressed Mood and Anxiety According to the Presence of Consciousness at the Time of Traumatic Accident / 신경정신의학

OBJECTIVES: This study investigated PTSD prevalence, symptoms, depressed mood and anxiety, comparing two groups of the patients in trauma; one who had experienced the loss of consciousness (group "A" here after) and the other group of patients who had not(group "B" here after). METHOD: Subjects were 120 patients(age18-66) who had received trauma(traffic accident, fall down) more than 1 month. Before they consisted of 56 patients who had experienced the loss of the consciousness(46.7%) and 64 who had not(53.3%). Men were 69 and women were 51. Clinician administered PTSD Scale, Beck Depression Inventory, State Trait Anxiety Inventory-I, II were administered. The factors such as sociodemographic variables, unconsciousness at the time of trauma, memory about traumatic accidents were considered. RESULT: Out of 120 subjects, 30 patients(25%) were diagnosed as PTSD: 17 from 56(30.4%) and 13 from 64(20.3%) were found in the group "A" and "B" respectively. Prevalence of PTSD was higher in the group "A". However, there was no significant difference between two groups(X2=1.607, p>0.05). The CAPS of group "A" showed significantly high frequency in the loss of interest, detachment, restricted affect, sleep difficulty, irritability/anger, concentration difficulty(p<0.05), while the group "B" scored high in intrusive recall and increased startle. The scores of BDI, STAI-I, II were significantly higher in the group "A"(t=-3.16, p<0.05)(t=-2.75, p<0.05, t=-3.38, p<0.05). CONCLUSION: PTSD was more frequent and depressed mood and anxiety appeared more often in the group who experienced the loss of consciousness. Thus the loss of the consciousness at the time of trauma prones of the aevelopment PTSD and to symptom of aepression and anxiety.

Quality of Life, Suicide Ideation, and Depressive Symptoms in Industrial Injury Patients / 신경정신의학

OBJECTIVE: As the occupational and traffic accidents are increased, patients who are treated for complications of accidents have been increased in recent years. Accidents including industrial injury affect the physical state of the patients and make social, vocational, and economic prob-lems, so that they can affect the whole life of the patients. We performed this study to compare subjective evaluation of quality of life, depressive symptoms, and suicide ideation in both industrial injury patients and control subjects in order to know how industrial injury affect patients in psychiatric aspect. METHOD: The subjects were 169 inpatients who met the inclusion criteria of industrial injury patients and 166 healthy control subjects. All subjects were male and their age is from 19 to 60 years old. Demographic variables, quality of life, depressive symptom, suicide ideation were assessed in subjects. The types of injury and the duration of treatment were assessed in patients. The quality of life was measured using the Korean version of SmithKline Beecham 'Quality of Life' Scale(KvSBQOL), and the suicide ideation was measured using the Scale for Suicide Ideation(SSI), and the depressive symptom was measured using the Dpression scale of Patient Problem Questionaire(PPQ) which were devised from Primary Care Evaluation of Mental Disorder(PRIME-MD). RESULTS: 1) There were no significant differences in the general demographic variables between industrial injury patients and control subjects. 2) Scores of KvSBQOL were significantly lower, and SSI and Depression scale of PPQ were significantly higher in the industrial injury patients than control subjects(p<0.05). 3) In industrial injury patients, threre was a correlation between the age and the scores of KvSBQOL(p<0.01). The scores of KvSBQOL were lowest in older than 30's, highest in 10's-20's. No significant correlation was recognized between the age and the suicide ideation, the depressive symptoms. Threre was a correlation between the marital status and the scores of KvSBQOL(p<0.01). In unmarried, divorced or separated state, the scores of KvSBQOL were significantly lower than married state. There was a correlation between the duration of treatment and the scores of KvSBQOL, the suicide ideation. As the duration of treatment was longer, the scores of KvSBQOL were significantly lower(p<0.01), and the scores of SSI were significantly higher(p<0.01). 4) In industrial injury patients, there was a significant correlation between the type of injury and the scores of KvSBQOL, the suicide ideation, and the depressive symptoms. The scores of KvSBQOL were highest in the L-spine injury patients, lowest in the C-spine injury and multiple contusion patients(p<0.01). The scores of SSI were higher in the C-spine injury and multiple contusion patients, lowest in the L-spine injury patients(p<0.01). 5) In subjects, there was significant correlation between the scores of KvSBQOL, the scores of SSI, and the Depression scale of PPQ. CONCLUSION: Industrial injury patients feel bad about the quality of life and have more depression and suicide ideation. As a results, psychiatric intervention is needed for prevention of depression and suicide due to industrial injury.

Immunocytochemical Study on the Changes of Cell-Death Controlling Factors in the Hippocampal Formation and Entorhinal Cortex of Aged Rats / 신경정신의학

OBJECTIVES: Hippocampal formation and entorhinal cortex play a part in learning and memory. This study sought to investigate the change of cell-death controlling factors in the hippocampal formation and entorhinal cortex of aged rats. METHODS: Ten aged rats and ten controls were studied. We performed immunocytochemical method using antibodies against NOS, VIP, c-fos , bcl-2, bax and p53 and in situ hybridization. RESULTS: 1) The number of nNOS-immunoreactive(IR) neurons in the entorhinal cortex was significantly decreased in the aged rats(>30%). Morphologically, the number of dendritic branches seemed to be decreased and the length of dendrites showed a tendency to by shortened in the aged group. A major loss of nNOS mRNA positive neurons was observed in the hippocampal formation of the aged rats(>30%). 2) VIP-IR neurons were predominantly bipolar cell. VIP-IR cells were mildly decreased in the hippocampus and subiculum(30%). 4) Bcl-2 mRNA positive neurons were moderately decreased in the hippocampus, subiculum and entorhinal cortex(15-30%), and severely decreased in dentate gyrus of the aged rats(>30%). 5) Bax-IR neurons were similarly distributed between the control and the aged rats, but bax-IR neurons of the aged group, as compared to the control group, were weakly immunostained. 6) P53-IR neurons were only observed in hippocampal CA1 region of the aged rats. CONCLUSION: These results indicate the involvement of neuronal system containing NOS, VIP, c-fos, bcl-2 and p53 in the brain aging process, and provide the morphological evidence for the changes in immunoreactivity of cell-death controlling factors in the hippocampal formation and entorhinal cortex of aged rats.

A Study of Predictive Factors of Treatment Response to Sertraline in Patients with Obsessive-Compulsive Disorder / 신경정신의학

OBJECTIVES: The pharmacologic treatment of obsessive-compulsive disorder(OCD) with serotonergic antidepressant agents is well established in clinical psychiatry on the basis of serotonin hypothesis. Studies on predictive factors of treatment response to OCD are relatively scarce. The author compared the demographic factors, age of onset, length of illness, family history of mental illness, previous drug history for OCD, severity and type of symptoms between the drug responders and non-responders to find out the predicitive factors that may be related to treatment response. METHODS: The subjects were 31, both inpatients and outpatients who met the diagnostic criteria for OCD by DSM-IV and scored 20 or higher on the Yale-Brown Obsessive-Compulsive Scale(Y-BOCS) completed 12-week trial of sertraline. Y-BOCS, National Institute of Mental Health Obsessive-Compulsive Scale(NIMHOCS), Clinical Global Impression Scale(CGI) were scored to measure the changes of obsessive-compulsive symptoms, and Hamilton Anxiety Scale(HAM-A) was measured at each visit. RESULTS: 1) The responders, defined as achieving at least a 40% decrease in the Y-BOCS total score and more than a 2 point decrease in CGI score, were 17(54.8%), and non-responders were 14(45.2%). Responders tended to show later onset(p<0.1), and shorter duration of illness(p<0.05), and less previous drug therapy for OCD(p<0.05) than non-responders. There were no significant differences in family history of mental illness between the two groups. 2) The baseline Y-BOCS compulsive score was significantly lower in responders(p<0.05), although there was no significant difference in the baseline severity of other measures. 3) The obsession of contamination and washing behaviors were more frequent, but compulsive counting was not shown, in responders(p<0.05). The pathological doubt tended to be more common in nonresponders(p<0.1). CONCLUSIONS: In summary, the patients with shorter duration of illness, less prior drug therapy for OCD, and less severe compulsive behaviors, and the obsession of contamination and washing behaviors are expected to be better outcome with sertraline, whereas compulsive counting are the predictor of poor response.

Early Development and Premorbid Social Adjustment during Childhood and Adolescence in Schizophrenic Patients / 신경정신의학

OBJECTIVES: Schizophrenia, one of the major mental illnesses, shows abnormal developmental patterns such as delayed developmental milestones, impaired language and motor function, and poor premorbid social adjustment long before the onset of clinical symptoms of illness. In this study, we tried to find out developmental patterns and premorbid adjustment during childhood and adolescence in Schizophrenic patients. METHODS: The subjects were 56 inpatients (26 male patients and 30 female patients) who met the diagnostic criteria for schizophrenia by DSM-IV and 52 healthy control subjects (25 male patients and 26 female patients). Interview with subjects and their families and the review of medical records were done to assess sociodemographic factors, timing of developmental milestones, language and motor function of childhood, and timing of sexual maturational events. Obstetrical Complication Scale of Lewis was used to get information on the subjects' prenatal and perinatal history, and Premorbid Social Adjustment Scale (PSAS) to assess premorbid adjustment. RESULTS: 1) There were no significant differences in the rates of obstetrical complications. The deveolpmental milestones during infancy such as sitting, walking, age of first sentence were significantly delayed in the Schizophrenics than in the controls (p<0.05). 2) Disturbances of speech and language development were significantly more common in the schizophrenics than in the controls (p<0.05), but there were no significant differences in the rates of disturbance in motor development. Mean ages of reading and writing were significantly delayed in schizophrenics than in the controls (p<0.05). No significant differences were found between males and females for either language disturbance or motor disturbance in the Schizophrenics. 3) During adolescence, premorbid adjustment was poorer in Schizophrenic patients (p<0.05). The Schizophrenic patients scored significantly worse than the controls on both sociability and schooling domains (p<0.05). There was a trend for correlation between poor premorbid functioning and early age of onset, but it failed to achieve statistical significance (Spearman's coeff =-0.27, p=.07). 4) Male Schizophrenic subjects showed poorer premorbid functioning on schooling domain than female Schizophrenic subjects (p<0.05). No significant difference was recogni ed in timing of sexual maturational events between Schizophrenics and controls. CONCLUSION: In summary, the Schizophrenics were significantly delayed in infantile developmental milestones, impaired in development of language, delayed mean age of reading and writing, and showed poorer premorbid social adjustment than the controls.

Efficacy and Safety Profile of Risperidone in Schizophrenia: Open Multicenter Clinical Trial / 신경정신의학

OBJECTIVE: The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. METHOD: This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points: at baseline, and 1,2,4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. RESULTS: 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action: a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. CONCLUSIONS: This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

Effect of Atypical Antipsychotics, Risperidone on Serum Creatine Phosphokinase / 대한정신약물학회지

OBJECTIVES: This prospective study was designed to investigate the effect of serotonergic atypical antipsychotics on serum creatine phosphokinase. METHOD: The subjects were 60 inpatients who were medicated risperidone and nemonapride, atypical antipsychotics. The symptoms of NMS such as fever and muscle rigidity and the level of CRK of all subjects were assessed on the 5th, 10th, 20th, and 30th medication day. RESULTS: Sociodemographic variables, such as sex and mean age and number of intramuscular injection were not different between the risperidone and the nemonapride group. Maximum dosage of antipsychotics (chlorpromazine equivalent) was significantly higher in the nemonapride group. Fever and muscle rigidity were not different between two groups (p>0.05). The change of serum creatine phosphokinase was significantly higher in the risperidone group than the nemonapride group (p<0.05). CONCLUSIONS: Serum CRK showed a significant increase in risperidone than nemonapride group. Such a finding is primarily caused by the effect of atypical antipsychotics mediating serotonergic effects. It is not recommanded to stop the medication by misunderstanding the effect as a prodrome symptom of NMS.

Computerized Defense Mechanisms in Panic Disorder / 신경정신의학

Despite the indications that psychodynamic factors may be important in understanding and treatment of panic disorder, these have not been studied systematically. In this report, self-rating Ewha Defense Mechanism Test(EDMT) was used to test the hypotheses that 1) panic patients would use different defense mechanism from normal controls, 2) panic patients would use lower-maturity defenses than normal controls. Twenty-two subjects meeting the DSM-IV criteria for panic disorder and 22 normal controls were given self-rating EDMT, and were compared about the use and maturity level of defenses between the two groups. Panic subjects scored significantly much higher than normal controls on the defenses of displacement and acting out, and on the controlling as a major defense mechanism. Also, the use of neurotic defense mechanisms was more frequent in panic subjects.

Serum Immunoglobulin and Complement Levels in Schizophrenics / 신경정신의학

OBJECTIVE: The purpose of this study was to elucidate the biological correlates of schizophrenia by measuring the change of serum immuneglobulin and complement levels and investigating a relationship of clinical symptoms to serum immunoglobulin and complement levels in schizophrenics. METHODS: The subjects were 27 inpatients, 13 men and 14 women, who met the diagnostic criteria for schizophrenia by Diagnostic and Statistical Manual of Mental Disorders IV(DSM-IV) and 24 normal controls, 8 men and 16 women. The serum immunoglobulin and complement levels of patients were measured at admission day and artier 2 weeks of treatment. Immunoglubulins and complement levels were obtained in serum using nephelometry. Positive and Negative Syndrome Scale(PANSS) were used to determine the clinical symptoms . RESULTS: 1) The serum IgG(p<.01) and IgM(p<.05) levels of schizophrenics measured at admission day were significantly lower than those of normal controls. 2) The serum C3 level significantly(p<.01) correlated with positive syndrome score. 3) The serum IgG levels of schizophrenics were significantly(p<.05) increased artier 2 weeks of treatment, especially in female schizophrenics. 4) The correlations of serum IgG, IgA, IgM, C3 and C4 to positive and negative syndrome scores of PANSS after treatment failed to get significant result. CONCLUSION: It Is suggested that the Immune function of schizophrenics appears to be decreased when compared with normal controls and is slightly increased with clinical improvement. Significant correlation between C3 and positive syndrome score at admission suggests possibility of immunologic marker of acute schizophrenia.

A Case of Rapid Cycling Affective Disorder in Patient with Severe Premenstrual Syndrome / 신경정신의학

Authors report a case of rapid cycling affective disorder(RCAD) who has suffered severe premenstrual syndrome since her monarch. Even if what relationship and etiology these disorders may have are undetermined, premenstrual syndrome and RCAD indeed share many characteristics and estrogen may have central role in these disorders. Patient showed a significant decrease of cerebral blood flow of right temporal area on SPECT It is impressive that carbamazepine was more effective than lithium in treatment of this RCAD case.

Relationship between Urine HVA and 5-HIAA Concentrations and Symptoms in Chronic Schizophrenia / 대한정신약물학회지

OBJECTS: This study was purposed to investigate the relationship between urine HVA and 5-HIAA concentrations and clinical symptoms in chronic schizophrenia. METHODS: 272 patients with chronic schizophrenia, diagnosed by DSM-IV criteria, were performed to measure urine HVA and 5-HIAA concentrations and to evaluate the clinical symptoms by using BPRS, PANSS, YBOCS and HAM-D. RESULTS: Urine HVA and 5-HIAA concentrations showed significant correlation with BPRS, positive scale, negative scale and general psychopathology in PANSS and urine HVA/5-HIAA ratios found no significant correlation. Urine HVA concentrations showed significant correlattion with urine 5-HIAA concentrations and urine HVA/5-HIAA ratios had a negative correlation with urine 5-HIAA concentration. As a result of stepwise multiple regression, urine HVA concentrations were significantly correlated with BPRS and positive scale in PANSS and Urine 5-HIAA concentrations were significantly correlated with BPRS. Urine HVA/5-HIAA ratios had significant correlation with HAM-D and BPRS. CONCLUSION: These findings support the hypothesis that the role of central dopamine and serotonin system and the functional interaction of both neurotransmitters are important to clinical symptom formation of chronic schizophrenia.

The Therapeutic Effect of Sertraline in Treatment-resistant Schizophrenics / 대한정신약물학회지

OBJECT: This study was undertaken to know whether there is any therapeutic effecets of sertraline in treatment-resistant schizophrenics. METHOD: Seventy seven treatment-resistant schizophrenic patients, to whom the same antipsychotics as usual were administered, were randomly assigned to two groups; to the experimental group, sertraline was and to the controlled group, placebo was administered adjuntively for 6weeks in single blind design. We assessed psychopathology by BPRS, PANSS, YBOCS, HRSD, and SCL-90-R. RESULTS: BPRS, positive scale of PANSS, and HRSD were significantly decreased in experimental group and statistically siginificant differences between the experimental group and placebo group. Negative scale of PANSS and YBOCS were significantly decresed in experimental group but no statistically significant differences between the experimental group and placebo group. The therapeutic effect of sertraline was occurred within 3rd weeks. CONCLUSION: We suggested that sertraline may be useful in the treatment of schizophrenic symtom in treatment-resistent schizophrenia, especially in positive and depressive symptoms.
