Efficacy and Safety of Escitalopram, Desvenlafaxine, and Vortioxetine in the Acute Treatment of Anxious Depression: A Randomized Rater-blinded 6-week Clinical Trial

Objective@#Anxious depression is associated with greater chronicity, higher severity of symptoms, more severe functional impairment, and poor response to drug treatment. However, evidence for first-choice antidepressants in patients with anxious depression is limited. This study aimed to compare the efficacy and safety of escitalopram, desvenlafaxine, and vortioxetine in the acute treatment of anxious depression. @*Methods@#Patients (n = 124) with major depressive disorder and high levels of anxiety were randomly assigned to an escitalopram treatment group (n = 42), desvenlafaxine treatment group (n = 40), or vortioxetine treatment group (n = 42) in a 6-week randomized rater-blinded head-to-head comparative trial. Changes in overall depressive and anxiety symptoms were assessed using the 17-item Hamilton Depression Rating Scale (HAMD) and Hamilton Anxiety Rating Scale (HAMA), respectively. @*Results@#Patients demonstrated similar baseline-to-endpoint improvement in scores and similar response and remission rates for HAMD and HAMA. Analysis of the individual HAMD items revealed that desvenlafaxine significantly reduced anxiety somatic scores (p= 0.013) and hypochondriasis scores (p = 0.014) compared to escitalopram. With respect to the individual HAMA items, desvenlafaxine treatment showed significantly lower scores for respiratory symptoms (p = 0.013) than escitalopram treatment and cardiovascular symptoms (p = 0.005) than vortioxetine treatment. The treatments were well tolerated, with no significant differences. @*Conclusion@#Our results indicated no significant differences in the efficacy and tolerability of escitalopram, desvenlafaxine, and vortioxetine in this subtype of patients with anxious depression during the acute phase of treatment.

Association of Antipsychotics and Behavioral and Psychological Symptoms of Dementia With Cognitive Decline in Subjects With Alzheimer’s Disease

Objective@#Neuropsychiatric symptoms are common among patients with major neurocognitive disorder. Antipsychotic medica-tions have been widely used to manage behavioral and psychological symptoms of dementia (BPSD), however efficacy and safety of these agents are conflicting. In this study, we tried to overview the association of antipsychotic medication use and neuropsychi-atric symptoms with cognitive decline in patients with Alzheimer’s disease. @*Methods@#We reviewed the medical charts of patients who were diagnosed as major neurocognitive disorder due to Alzheimer’s disease from November 2014 to October 2015. We reviewed whether the subjects had used antipsychotics, and whether patients had neuropsychiatric symptoms. We used linear mixed models to examine the statistical difference between each group. @*Results@#Total of 106 subjects were included in the study. There was no statistically significant difference in cognitive function decline (Korean Version of Mini-Mental State Examination score change) between subjects with or without BPSD (p=0.62), and between subjects with or without antipsychotic medication (p=0.09). @*Conclusion@#There was no evidence that antipsychotic medication and BPSD are associated with more cognitive decline. Findings imply that neuropsychiatric symptoms and cognitive impairment come from different etiologic causes, which highlights the heterogeneity of the disorder. Clinician should decide whether to use antipsychotic medication while carefully considering the effect and side effects of antipsychotic medication throughout the treatment period.

Differences in Characteristics/Complaints and Referral of Attention-Deficit/Hyperactivity Disorder Patients with and without Depression: Focus on Korean Children and Adolescents / 우울ㆍ조울병

Background@#Children and adolescents with attention-deficit/hyperactivity disorder (ADHD) and depression present with different clinical characteristics compared to those without other psychiatric comorbidities (i.e., ADHD alone). This study aimed to determine the differences in clinical characteristics, complaints, and referral routes between patients with ADHD with and without depression. @*Methods@#The study included 1,231 children and adolescents in Korea. The demographic characteristics, referral routes, and chief complaints were identified and analyzed using the subjects’ electronic medical records of their first outpatient visit. @*Results@#The mean age and proportion of female subjects with depression and ADHD (ADHD-D, n=120) were significantly higher than those of patients with ADHD alone (ADHD-O, n=1,111). Furthermore, referral requests by the caregiver (p=0.037) and patient (p=0.006) were significantly higher in the ADHD-D group. In contrast, referrals via schools (p=0.009) and other medical institutions (p<0.001) were significantly higher in the ADHD-O group. There were more complaints of depression, anxiety, mood dysregulation, suicidal ideation, and self-harm behaviors among the patients in the ADHD-D group. However, complaints of inattention were more common among the patients in the ADHD-O group compared to those in the ADHD-D group (p<0.001). @*Conclusion@#This study revealed several differences in the demographic characteristics, referral routes, and chief complaints of the patients and caregivers between patients with ADHD with and without coexisting depression. Further investigations using structured psychiatric diagnostic tools are warranted.

The Impact of Paliperidone Palmitate on Hospitalization in Patients with Schizophrenia: A Retrospective Mirror-image Study

OBJECTIVE: Whether long-acting injectable antipsychotics (LAI) are superior to oral antipsychotics remains a controversial question, and results vary depending on the study design. Our study was performed to compare outcomes of oral anti-psychotics and paliperidone palmitate (PP) in clinical practice by investigating the numbers of admissions and bed days. METHODS: We performed a retrospective observational mirror-image study at a single medical center, reviewing medical charts to obtain the clinical data. Forty-six patients with a diagnosis of schizophrenia or schizoaffective disorder who had received at least two doses of PP were included in the analysis. The Wilcoxon signed-rank test was used to compare the numbers of bed days and admissions 1 year before starting PP with those numbers at 1 year after. RESULTS: The mean number of admissions fell from 0.83 to 0.17 per patient (p < 0.0002), and the median fell from 1 to 0. The mean number of bed days decreased significantly, from 24.85 to 8.74 days (p < 0.006). The outcomes remained similar in sensitivity analyses set up with different mirror points. CONCLUSION: Our results indicate that initiating PP reduced the mean numbers of hospital admissions and bed days compared with prior oral medication. LAIs may thus be cost effective in practice; its use bringing about cost reductions greater than its purchase cost.

Comparison of Inflammatory Markers Including C-Reactive Protein between Treatment Resistant Schizophrenia and Non-Treatment Resistant Schizophrenia / 생물치료정신의학

OBJECTIVES: The present study is to investigate inflammatory markers and associated clinical factors between treatment resistant schizophrenia and non-treatment resistant schizophrenia.METHODS: Of the 116 schizophrenia subjects who were hospitalized for ac ute symptomatic treatment, 19 patients (16%) were treated with clozapine as a treatment resistant schizophrenia(TRS) and 97 patients(84%) were treated with other atypical antipsychotics as a non-treatment resistant schizophrenia(Non-TRS). Various inflammatory markers including C-reactive protein(CRP) and clinical factors were retrospectively evaluated with electrical medical records.RESULTS: There were significant differences between two groups in disease duration(p =0.015), number of admission (p =0.003), Clinical Global Impression(p <0.001) but other demographic and clinical variables including previous antipsychotics use did not show significant differences. In terms of hematologic profiles, TRS group demonstrated higher CRP level(p =0.006), lower neutrophil count(p =0.012), and lower hemoglobin level(p =0.003) compared with non-TRS group. Body mass index was significantly correlated with CRP(r=0.318, p =0.001).CONCLUSION: The elevated level of serum CRP in TRS suggests that treatment resistance in schizophrenia may be associated with inflammatory response. However, retrospective study design and small number of subjects could limit this interpretation.

The Risk Evaluation of Delirium in Elderly Patients with Lower Extremity Fractures

OBJECTIVE: Delirium is very common in orthopedic elderly patients and increase comorbidity and mortality rates. By controling the risk factors of delirium, prevention strategy can be effective and reduce negative outcomes. The purpose of this study was to explore the usefulness of delirium risk assessment with some simple collateral questionaires. METHODS: The subjects were 50 elderly patients (≥65 years old) who admitted to a department of orthopedic surgery for operations of lower extremity fractures. They were evaluated with Diagnostic and Statistical Manual of Mental Disorders, fifth edition, Confusion Assessment Method and Korean Dementia Screening Questionnaire (KDSQ) by psychiatrists. The demographic data, medical histories, and orthopedic chart were checked through medical records of patients. RESULTS: 27 subjects (54.0%) were diagnosed as delirium. There was a significant difference between delirium group and control group with all KDSQ scores. Depressive category of KDSQ score had the highest correlation (coefficient=0.399) and can be independent risk factor of delirium (p=0.045). CONCLUSION: Cognitive impairment and depressive symptoms have high correlation with delirium. We found that just a few questions of cognitive impairment and depressive symptoms by caregivers can evaluate the risk factors of delirium. The simple collateral questionaires can be useful tool for exploring delirium risk factors.

Improving the Screening Instrument of Bipolar Spectrum Disorders: Weighted Korean Version of the Mood Disorder Questionnaire

OBJECTIVE: It is not easy to diagnose bipolar disorders accurately in the clinical setting. Although Korean version of the Mood Disorder Questionnaire (K-MDQ) is easily administered, it still has weakness regarding case finding. In this study, we suggest a new weighted version of the K-MDQ to increase its screening power. METHODS: Ninety-five patients with bipolar disorders and 346 controls (patients with schizophrenia, patients with depressive disorders, patients with anxiety disorders, and subjects without any psychiatric disease) were enrolled in this study. The subjects received brief information on the K-MDQ, and then independently completed the questionnaire. RESULTS: Using odds ratios, we constructed a new weighted K-MDQ (W-K-MDQ). Item 1 (feel so good or hyper) was weighted 7 times and item 4 (less sleep) 3.5 times. Item 7 (easily distracted) and item 11 (more interested in sex) were excluded. Part 2 (simultaneity) and 3 (functional impairment) were also excluded as in the original K-MDQ. The sensitivity of the W-K-MDQ with a cutoff value of 10 was enhanced to 0.789. The area under the receiver operating characteristic curve was increased to 0.837. CONCLUSION: We suggested a new formula for K-MDQ using 11 of its items. The W-K-MDQ can be easily applied with good sensitivity to screen for bipolar disorders in clinical settings in Korea. Further evaluations with larger samples are needed to establish the usefulness of the W-K-MDQ.

Relationship between Insight and Manic Symptoms in Stable Patients with Chronic Schizophrenia / 우울ㆍ조울병

OBJECTIVES: Patient insight is a very important factor in the management of schizophrenia. Manic symptoms can occasionally be identified by the patient, even in cases of schizophrenia. The aim of this study is to examine the relationship among patient insight, the psychotic and manic symptoms, and the demographic clinical variables.METHODS: Seventy-four participants (male 44, female 30) with chronic schizophrenia in community mental health facilities were evaluated according to the Korean version of the Scale to assess Unawareness of Mental Disorder (SUMD-K), the Korean version of Mood Disorder Questionnaire (K-MDQ), and the Brief Psychiatric Rating Scale (BPRS).RESULTS: The mean number of previous admissions was 3.85. The mean CGI-S score was 3.8 and a significant negative correlation (r=0.26) was shown with “awareness of mental disorder”. Thirty-five percent of subjects were K-MDQ positive (cutoff point=7 or more). Among the SUMD-K, “awareness of effect of medication” showed a significant negative correlation (r=−0.33) with the total K-MDQ score, but not with the total BPRS score. The negative correlation was more obvious in participants with negative K-MDQ (total K-MDQ score 6 or less, r=−0.31).CONCLUSION: A possible relationship was observed between these manic symptoms and patient insight. Identification of manic symptoms in schizophrenia would be considerable in a clinical setting.

Does Emotional Intelligence Fluctuate within Clinical Depressive Condition?

OBJECTIVE: Emotional intelligence (EI) is regarded an important factor related to psychiatric disorder. Most of previous studies of EI and depression only dealt with EI in present of depressive symptoms. Our study investigated EI both before and after remission of depression and to identify which component of EI is changeable by depression condition. METHODS: EI was evaluated for 23 depression patients and 44 normal control participants. Adult Emotional Quotient Test (AEQT) was used as subjective EI measure and Emotional Literacy Test (ELT) was used as objective EI measure to both groups. RESULTS: During the initial evaluation of the subjective EI, patient group reported significantly lower scores than control group on all AEQT sub-domains except ‘empathy’. However, group difference on ‘utilization’ disappeared after the remission evaluation. There was no significant difference within the objective EI measure. CONCLUSION: According to the result of the study, EI could be sub-divided into trait-dependent EI and state-dependent EI. Further implication, strength and limitation were discussed.

Incidence and Course of Depression in Patients with Alzheimer's Disease

OBJECTIVE: Depressive symptoms are common in Alzheimer's disease (AD) and they might influence the course and prognosis of AD. Depression could appear anytime in the course of the disease, and could either last considerably long or disappear easily. This study is intended to investigate the occurrence of depression in the course of AD and the risk factors of incidence. METHODS: This study targeted 1,272 AD patients without depressive symptoms at the start of this study in Korea. A total of 775 subjects completed the study, and the occurrence of depression was assessed after 12 months. Demographic information of subjects was collected and cognitive functions, overall functions, and depression severity were assessed at the start of this study and after 12 months. RESULTS: Among the 775 subjects, 103 subjects (13.29%) developed depression 12 months later. The MMSE-KC scores showed significant changes in both groups that developed depression and did not. In the univariate analysis, significant differences in the incidence of depression were found in terms of gender, the administration of the antidepressant at the baseline, the SGDS-K score, and the GDS score. The multiple logistic regression analysis showed that the increase in the incidence of depression was associated with a female, in the increase in SGDS-K score and the GDS score. CONCLUSION: The incidence of depression in the subjects who completed the 12-month follow-up observation was 13.29%. Moreover, in the multivariate analysis, a female gender and the severity of dementia, including the overall functions, seemed associated with the occurrence of depression.

Cognitive Impairment in Hip Fracture Patients without Underlying Neurologic Diseases: Risk Factors and Relationship to Early Functional Recovery: Preliminary Study

PURPOSE: The aim of this study is to examine the risk factors of cognitive impairment in elderly hip fracture patients with no underlying neurologic disease, and to determine its effect on functional recovery postoperatively. MATERIALS AND METHODS: From August 2012 to August 2013, 39 patients older than 65 years of age, who underwent hip fracture surgery and were followed-up for a minimum of 1 year at Hallym University Sacred Heart Hospital, were enrolled. All patients were assessed using Korean version of Mini-Mental State Examination (MMSE-K) after admission. All patients were divided into cognitive normal group (MMSE-K> or =24) and cognitive impairment group (MMSE-K<24). WOMAC (Western Ontario and McMaster University) score and Harris hip score were used for assessment of functional recovery at 6-month follow-up. RESULTS: Sixteen patients (41.0%) were classified as the cognitive impairment group. The number of underlying diseases was the only statistically different factor between the two groups. In the evaluation of functional outcome, the functional decline was less in the cognitive normal group. Risk factors for cognitive impairment in elderly hip fracture patients were old age, high body mass index, and the number of underlying diseases, particularly an endocrinologic disease like diabetes. CONCLUSION: Cognitive impairment in elderly patients may have a negative effect on functional recovery after hip fracture surgery. Therefore, we recommend routine evaluation of cognitive function in elderly hip fracture patients even with no underlying neurologic disease.

Opioid Analgesics and Depressive Symptoms in Burn Patients: What Is the Real Relationship?

OBJECTIVE: Major burn injuries are strongly associated with both psychological trauma and severe pain, and opioids are the mainstay analgesics for the treatment of severe burn pain. The objectives of this study are to find the complex relationship between opioid dose, depression, and post-traumatic stress disorder (PTSD) symptoms during the acute management of pain in burn patients. METHODS: The symptoms of depression and PTSD were assessed in 43 burn patients immediately following wound stabilization and 2 weeks after the initial evaluation. RESULTS: Total opioid doses and Hamilton Depression Scale (HAMD) scores obtained during the second evaluation were positively but weakly correlated after controlling for age and total burn surface area (R=0.33, p=0.03). Moreover, pain management with opioids was significantly more common in burn patients with low Clinician Administered PTSD Scale scores (evaluation 1) and high HAMD scores (evaluation 2) (F=6.66, p=0.001). CONCLUSION: High opioid dose following acute burn trauma might have correlation with depressive symptoms. Monitoring of depressive symptoms may be important following acute burn trauma and consequent opioids pain management, particularly when PTSD symptoms appear minimal during the early stabilization of patients.

The Relation of Blood Iron Level with Frontal Function in Children with Attention-Deficit/Hyperactivity Disorder / 신경정신의학

OBJECTIVES: Attention-deficit/hyperactivity disorder (ADHD) is a neurodevelopmental disorder showing many neuropsychological deficits. Many environmental risk factors have been thought to increase the risk for the disorder. We examined blood iron levels in children with ADHD and a control group to find an association between iron deficit and diagnosis, neuropsychological characteristics and clinical features. METHODS: An ADHD group (n=50) and control group (n=45) of children 6-12 years of age were recruited. Both groups were diagnosed by semi-structured interview, and they were evaluated using the Korean version of the ADHD Rating Scale (K-ARS), Korean version of IOWA Conner's Rating Scale (K-IOWA), intelligence quotient (IQ), and neurocognitive function tests (continuous performance test, children's color trails test, Stroop color-word test). Iron levels in blood were determined using the inductively coupled plasma mass spectrometry instrument. Independent t-test and correlation were used to determine the relation of blood iron levels with symptom ratings and neurocognitive function. Logistic regression was performed to determine the diagnostic value of blood iron levels. RESULTS: Blood iron levels were significantly lower in ADHD than in control and showed negative correlation with K-ARS and K-IOWA scores. Blood iron levels showed positive association with IQ and Stroop color-word test results and negative association with results of continuous performance testing. Low blood iron levels predicted the diagnosis of ADHD. CONCLUSION: Lower levels of blood iron were associated with ADHD symptom severity, IQ, and frontal lobe-mediated neurocognitive function. As blood iron levels may influence ADHD, measurement of iron levels in blood may be useful for evaluation of symptoms and neurocognitive function in ADHD.

Predictors of Suicide Attempts in Clinically Depressed Korean Adolescents

We examined predictors of suicide attempts in clinically depressed adolescents in Korea and gender differences in suicidal behavior. In total, 106 adolescents diagnosed with depressive disorder were recruited in South Korea. We assessed various variables that might affect suicide attempts, and used a structured interview for the diagnosis of depression and comorbidities and to evaluate suicidality. Demographic and clinical characteristics of the subjects were compared between suicide attempt and non-suicide attempt groups and we examined significant predictors of suicide attempts. Gender differences in suicidal ideation and suicidal behavior were also analyzed. Among 106 depressed participants, 50 (47.2%) adolescents were classified in the suicide attempt group. Generally, the suicide attempt and non-suicide attempt group shared similar clinical characteristics. The suicide attempt group had more females, more major depressive disorder diagnoses, more depressive episodes, and higher suicidal ideation than the non-suicide attempt group. Suicidal ideation was the only significant predictor of suicidal attempt, regardless of gender. Higher suicidal ideation frequency scores and more non-suicidal self-injurious behaviors were shown in the female suicide attempt group than the male suicide attempt group. It is recommended that suicidal ideation be assessed regularly and managed rigorously to decrease suicide risks in depressive adolescents.

The Distribution of Depressive Symptoms among the Community-Dwelling Elderly

OBJECTIVES: This study was to understand the characteristics of depressive symptoms among the community-dwelling elderly. METHODS: Through a community mental health mass screening program in senior society, 197 elderly were evaluated for depressive symptoms with Korean version of Short form Geriatric Depression Scale (SGDS-K). The subjects were grouped into normal or caution groups with a cut-off score of 6. The response rate and odds ratio were calculated and compared within each question. RESULTS: Although they had low total score, many subjects in normal group have the symptoms of the question 2, 13, 5, 10, 7, 4 (in order). Question 12, 6, 8, 4, 14, 3 (in order) showed higher odds ratio in caution group than normal group. Questions belonged to a factor 'general depressive mood' scored much higher odds ratio than the other. CONCLUSION: Even the elderly with low score in SGDS-K might complain of symptoms such as decreased level of energy, activities, interests, and memory. However the subjects with high score tend to report feeling more worthless, afraid, helpless, bored, hopeless, and empty. It can be helpful to know the distribution of depressive symptoms for providing careful mental health service to the elderly dwelling in the communities.

The Protective Role of Resilience in Attenuating Emotional Distress and Aggression Associated with Early-life Stress in Young Enlisted Military Service Candidates

Early life stress (ELS) may induce long-lasting psychological complications in adulthood. The protective role of resilience against the development of psychopathology is also important. The purpose of this study was to investigate the relationships among ELS, resilience, depression, anxiety, and aggression in young adults. Four hundred sixty-one army inductees gave written informed consent and participated in this study. We assessed psychopathology using the Korea Military Personality Test, ELS using the Childhood Abuse Experience Scale, and resilience with the resilience scale. Analyses of variance, correlation analyses, and hierarchical multiple linear regression analyses were conducted for statistical analyses. The regression model explained 35.8%, 41.0%, and 23.3% of the total variance in the depression, anxiety, and aggression indices, respectively. We can find that even though ELS experience is positively associated with depression, anxiety, and aggression, resilience may have significant attenuating effect against the ELS effect on severity of these psychopathologies. Emotion regulation showed the most beneficial effect among resilience factors on reducing severity of psychopathologies. To improve mental health for young adults, ELS assessment and resilience enhancement program should be considered.

The Risk Factors of Delirium in Orthopedic Elderly Patients

OBJECTIVE: The aim of this study was to explore risk factors behind delirium in elderly inpatients with orthopedic problem. METHODS: The subjects were 94 elderly patients (> or =65 years old) who admitted to a department of orthopedic surgery. They were evaluated with Confusion Assessment Method (CAM) and were diagnosed by Diagnostic and Statistical Manual of Mental Disorders, fourth edition, text revision through direct interview with psychiatrists. The demographic data, medical histories, and orthopedic chart were checked through medical records of patients. RESULTS: 20 subjects (21.3%) were diagnosed as delirium, and among them, 10 subjects had hyperactive type (50.0%), 6 had hypoactive type (30.0%) and 4 had mixed type (20.0%). Delirium group had high systolic blood pressure (p=0.007) and plasma glucose level (p=0.001) at the admission day. They had low hemoglobin (p=0.002) and potassium level (p=0.017) after surgery. CONCLUSION: In our study, there were many delirium patients, and even though there were many hypoactive type patients. It is assumed that delirium occurs more at the surgery or damage with larger loss of blood. It is important that we take care of management of past diseases rather than presence of past diseases. It is necessary to develop guidelines which would help to find out high risk patients for delirium.

Impact of Depression and Emotional Intelligence on Suicidal Ideation of Patients with Major Depressive Disorder / 대한정신약물학회지

OBJECTIVE: There is much research on risk factors of suicide, but studies about what can play a protective role on suicide are limited. This study was conducted to investigate the impact of depression and emotional intelligence on suicidal ideation of patients with depression. We focused more on the role of emotional intelligence as a protective factor. METHODS: The participants (n=100) underwent a psychiatric interview which included the Mini International Neuropsychiatric Interview and the Columbia University Suicide Severity Rating Scale (C-SSRS). Beck's Depression Inventory (BDI) was also completed. For measuring emotional intelligence, both a self-report questionnaire (the Adult Emotional Quotient Test, AEQT) and an objective measurement based on ability model (Emotional Literacy) were conducted. RESULTS: In linear regression analysis, depressive symptom score was significantly associated with suicidal ideation. It was also shown that 'emotional expression' of AEQT and 'emotion perception' of Emotional Literacy are significantly associated with suicidal ideation. CONCLUSION: Against our expectation that emotional intelligence would be a protective factor on suicidal ideation, emotional expression and emotion perception might rather be a risk factor for suicidal ideation. The limitations of this study and suggestions for further research are also discussed.

The Relationship between Low Self-Esteem and Suicide Attempt in Patients with Major Depressive Disorder: A Pilot Study / 대한정신약물학회지

OBJECTIVE: Depression is a major risk factor for suicide, and several psychological factors such as low self-esteem are involved in suicide. The aim of this study was to investigate the difference in self-esteem between non suicide attempters and suicide attempters with major depressive disorder. METHODS: The study subjects consisted of 52 patients who received inpatient or outpatient treatments at the Hallym University Sacred Heart Hospital. All participants were diagnosed as major depressive disorder by Korean version of the Mini-International Neuropsychiatric Interview. Columbia Suicide Severity Rating Scale (C-SSRS) was used to evaluate patient's suicide attempt. They completed a questionnaire that included Rosenberg Self-Esteem Scale, Beck Depression Inventory (BDI) and Beck Scale for Suicide Ideation (BSI). RESULTS: A total of 52 subjects were evaluated by C-SSRS, and among them, 32 were non suicide attempters and 20 were suicide attempters. Compared to non suicide attempters, suicide attempters showed significantly lower levels of self-esteem (t=3.492, p=0.001) and higher levels of BSI (t=-4.890, p<0.001). Although there was no significant difference between two groups for severity of overall depressive symptoms, negative attitude subscale of BDI was higher in suicide attempters than non suicide attempters (t=-2.596, p=0.014). A stepwise multivariate logistic regression analysis showed that low self-esteem was significant association with suicide attempt after adjusted by negative attitude subscale of BDI and BSI (odds ratio=0.779, p=0.042). CONCLUSION: The present study indicated that low self-esteem plays a significant role in suicide attempters with major depressive disorder. Assessment of suicide risk should include not only suicide ideation and severity of overall depressive symptoms but also low self-esteem.
