Objectives : This study was aimed to investigate the associations of childhood trauma with psychopathology and clinical characteristics in patients with schizophrenia. Methods : This study enrolled 66 inpatients with schizophrenia. Korean Childhood Trauma Questionnaire (K-CTQ) and Life Event Questionnaire (LEQ) were administered to assess childhood trauma. Psychopatholgy and clinical characteristics were assessed with the Positive and Negative Syndrome Scale (PANSS), Beck Depression Inventory (BDI), Korean Version of Internalized Stigma of Mental Illness (K-ISMI), Perceived Stress Scale (PSS), and visual analogue scale of EuroQoL-5 Dimension Index (EQ-5D). Results : Total scores on K-CTQ were positively associated with scores on the BDI, K-ISMI, PSS, and PANSS and negatively associated with the score on the EQ-5D. Among subscales of K-CTQ, emotional abuse was significantly associated with all measures for psychopathology and clinical characteristics. Patients with physical abuse (36.5%), emotional abuse (30.2%), or bullying (30.6%) according to the LEQ showed sighificanlty higher the ISMI score and lower EQ-5D score. Emotional abuse and bullying were also significantly associated with higher scores on BDI and/or PSS. Conclusion : Our results suggest that childhood trauma negatively influences on internalized stigma, depression, perceived stress and quality of life in patients with schizophrenia. Clinicians should carefully evalute and manage childhood traumatic experience of patients with schizophrenia.

Objective: The purpose of this study was to investigate the effects rhythmic and non-rhythmic aerobic exercises on depression and balance of healthy elderly people. Design: Randomized controled trial. Methods: Nineteen older subjects were randomly divided into 2 groups for rhythmic and non-rhythmic aerobic exercises. Both aerobic exercises consisted of functional movements such as turning in opposite directions, and running in place, the exercise consisted of movements that could activate balance. The rhythmic training group initially used music with 8 beats, and then later progressed to 16 beats. Additionally, we adjusted the pace of the music using songs from 125 beats per minute (bpm) to 160 bpm. Both groups were exercised for 50 minutes a day, twice a week, for a total of 8 weeks. We measured the condition of the patients before the intervention, and after 8 weeks of intervention. The Beck depression inventory (BDI) was used to measure the degree of depression. The Berg balance scale (BBS) was used to measure static and dynamic balance ability. We measured the subject's subjective balance confidence using the fall efficacy scale (FES). Results: Both groups showed significant improvement in BDI, BBS, and FES (p<0.05). The rhythmic aerobic exercise group showed a significant improvement only in the BBS change values compared to the non-rhythmic group (p<0.05). Conclusions: According to this study, both rhythmic and non-rhythmic aerobic exercises resulted in significant improvement in the degree of depression and balance ability of the elderly. The rhythmic aerobic exercise was more effective for dynamic balance ability.

This study was aimed to investigate dysfunctional attitudes, stress coping strategies and depressive symptoms in psychiatric patients. The subjects of this study consisted of 210 patients(138 schizophrenic patients, 29 depression patients, 43 alcohol dependence patients) according to DSM-IV criteria. Futhermore, the instruments were K-BDI(Beck Depression Inventory-Korean version), DAS(Dysfunctional Attitude Scale) and multidimensional coping strategy scale. The results were the following. 1) There were statistically significant correlations between depressive symptoms and dysfunctional attitudes in psychiatric patients. 2) In terms of coping strategies, there were positive correlations between depressive symptoms and focus on and venting emotions, accommodation, active forgetting, self-criticism, positive comparison, fatalism, passive withdrawal. Whereas, there was significant negative correlation between depressive symptom and active coping. 3) In terms of coping strategies, there were significant correlations between dysfunctional attitudes and focus on and venting emotions, active forgetting, self-criticism, positive comparison, fatalism, passive withdrawal. 4) Depression groups reported significantly higher BDI scores than schizophrenia groups. 5) In depression groups, DAS scores were significantly higher than those in schizophrenia groups. 6) In terms of coping strategies according to diagnosis, there were significant differences in venting emotions, active forgetting and self-criticism. As for venting emotions, alcoholic groups were scored significantly higher than schizophrenic groups. As for active forgetting, depression groups were scored significantly higher than schizophrenic groups. In self-criticism, depression groups and alcohol dependence groups reported significantly higher scores than schizophrenic groups.

Objectives : The aim of this study was to investigate relationship between perceived stress level, cognitive emotion regulation (CER) strategy and hope in group with high depressive symptom and higher-level perceived stress (H-H) and group with high depressive symptom and lower-level perceived stress (H-L) in patients with depression. Method : A total of 85 patients (over score of 16 by Beck depression Inventory; BDI) were surveyed with Cognitive emotion regulation questionnaire (CERQ), Perceived stress scale (PSS), and The state hope scale (SHS). Mean scores of CERQ and SHS were compared between relatively higher perceived stress and lower perceived stress groups. Correlation analysis and multiple linear regression analyses were performed to identify the effect of BDI, PSS and CER strategy on SHS in two groups. Results : In ANOVA, the level of hope and maladaptive CERQ score proved to be significantly lower among the H-H group than among the H-L group, while adaptive CERQ scores were not. In Regression analysis, the effective CER strategy in SHS were 'Refocus on planning' in H-H group, while it was 'Acceptance' CER strategy in H-L group. The final regression model explained 36% of the variance of SHS in H-H group and explained 21% of SHS in H-L group. Conclusion : These findings suggest that 'Refocus on planning' and 'Acceptance' cognitive emotion strategy are helpful in promotion of state hope on depression. Especially, 'Refocus on planning' strategy is more effective in high depressive symptom and high-perceived stress level, while 'Acceptance' strategy help to promote hope in high depressive symptom and low-perceived stress level in patients with depression.

Objective : The aim of this study was to investigate the relationship between subjective sleep problems and various types of traumatic events of patients with depressive disorder. Methods : A total of 411 patients diagnosed with depressive disorders were recruited in this study. The participants filled out Life Time Events Checklist (LEC), Pittsburgh Sleep Quality Index (PSQI), Beck Depression Inventory (BDI), and State-Trait Anxiety Inventory (STAI). We used the independent t-test and analysis of covariance to compare each component of PSQI between depressive patients with and without traumatic experiences. Results : The groups of patients who experienced a serious accident at work, home or during recreational activity, sexual assault, other unwanted or uncomfortable sexual experience, life-threatening illness or injury, and sudden, unexpected death of a near and dear one showed lower scores in a few components of PSQI. Sleep disturbance was a common problem in all five groups. Lower subjective sleep quality and longer sleep latency was observed in three groups. There were no differences in the other components of PSQI among groups. Conclusion : This study showed that various types of traumatic events may have different effects on subjective sleep quality as a consequence of the traumatic event which they had experienced.

Objectives: Obstructive sleep apnea syndrome (OSAS) is the most common form of sleep-disordered breathing and often presents with comorbid depressive symptoms. In this study, we evaluated the relationship between depressive symptoms and sleep parameters as measured by nocturnal polysomnography (NPSG) and simultaneous wrist actigraphy. Methods: Two hundred sixty-four subjects with clinically suspected cases of OSAS underwent one-night polysomnography, while simultaneously wearing a wrist actigraphy device. They also completed two questionnaires；the Epworth Sleepiness Scale-Korean version (ESS-K) and the Beck Depression Inventory (BDI). Of the cases studied, 105 subjects were proven by NSPG to have OSAS without other sleep disorders. NPSG and wrist actigraphy data from the subjects were analyzed. Pearson correlation and paired t-test were used in order to evaluate the relationship between depressive symptoms and sleep-parameters. Results: Mean age of the subjects was $46.1{\pm}13.1$ years. Means of the ESS-K score and BDI scores were $10.9{\pm}4.7$ and $12.8{\pm}8.1$, respectively. NPSG sleep parameters significantly differed from those of wrist actigraphy. There was no correlation found between subjects' respiratory disturbance index (RDI) and BDI scores. When directly comparing sleep parameters between subjects who were more depressed versus subjects who were less depressed, both total sleep time and sleep efficiency were decreased in the more depressed. A correlation between RDI and ESS-K scores was also found in the more depressed group. Conclusions: Although our findings suggest that there is no relationship between RDI and depressive symptoms, there are other significant differences in the sleep parameters between subjects who are more depressed versus those without depression. We recommend that patients with depression should also be evaluated for clinical symptoms of OSAS.

Objectives : This study was to provide normative data of Korean version of DSI(K-DSI), a sensitive measure of relatively minor stressors that could be administered daily. Methods : K-DSI was administered in 524 adults, age of 19 or over, daily for 1 week. On the seventh day, Becks Depression Inventory(BDI), State-Trait Anxiety Inventory(STAI), and Social Readjustment Rating Scale(SRRS) were also given to test the convergent validity. Analyses(ANOVA or t-test) were conducted to examine the potential effects of demographic variables on K-DSI score. Internal consistency for reliability and Pearson's corelation coefficient with BDI, STAI, SRRS for convergent validity were computed. Percentile scores were calculated for daily and weekly K-DSI Event, Impact and I/E Ratio scores. Results : K-DSI scores in women were higher than those in men. According to age and educational level, the younger and the higher educational level the normative groups were, the higher were K-DSI scores. Among the 5 categories of the inventory, the category of cognitive stressors was highest. Internal consistency of K-DSI(Cronbach's $\alpha$) was .99. Daily and Weekly events and impacts scores were significantly correlated with the scores of State-Trait Anxiety Inventory, Social Readjustment Rating Scale, and Beck Depression Inventory. 75 percentile scores of the daily/weekly Events, Impacts, and I/E ratio were 17/118 - 124, 57/368 - 389 and 3.48 - 3.49/3.47 - 3.48 respectively. And 95 percentile scores of daily/weekly Events, Impacts, and I/E ratio were 57/151- 161, 405/1038 - 1122, and 4.72 - 4.86/4.46 - 4.56 respectively. Conclusion : Reliability and validity of K-DSI were tested satisfactorily. Authors presented the normative data of K-DSI for Koreans. K-DSI could be a useful measure in clinical settings or researches to assess the minor stressors frequently experienced in everyday life.

Objectives : There has been substantial evidence that patients with chest pain have depression and anxiety, and show impaired quality of life (QoL). This study aimed to campare the QoL according to types of chest pain and to examine the impact of depression and anxiety on QoL in patients with chest pain. Methods : Forty-seven patients with chest pain were divided into Cardiac-Typical Chest Pain (CTCP, n=22) and Non-Cardiac-Atypical Chest Pain groups (NCACP, n=25) according to the pain characteristics and cardiovascular disease. Patients were assessed for depression using the Beck Depression Inventory (BDI), for anxiety using the State-Trait Anxiety Inventory (STAI), and QoL was assessed using the Korean version of the SmithKlein Beecham 'Quality of Life' Scale (KvSBQOL). Results : Compared with the CTCP group, the NCACP group reported significantly higher anxiety, and lower QoL. There was no significant difference in QoL between the two groups after adjusting for anxiety. The QoL was associated with depression and trait-anxiety in the CTCP group, and with trait-anxiety in the NCACP group. Conclusion : The findings suggest that there are different effects of depression and anxiety on QoL in individuals with CTCP and NCACP. Understanding about these differences can be important in the treatment of patients with chest pain. A large prospective study is needed to confirm these results.

This study investigated the mediating effects of depression on the relationship between perceived problem solving ability and suicidal ideation. 548 college students were examined with PSI(Problem Solving Inventory), BDI(Beck Depression Inventory) and SSI(Scale for Suicidal Ideation). To explore the relationship among these variables, correlation analysis was undertaken. Regression analysis was then applied to test the mediating effects of depression. In the results, perceived problem solving ability, depression and suicidal ideation were correlated positively. Depression operated as a factor to mediate between the perceived problem solving ability and suicidal ideation. This mean that perceived problem solving ability impact indirectly, rather than directly, on suicidal ideation. These results suggest the importance of psychological intervention to improve depression and perceived problem solving ability that affect suicidal ideation.

Objectives：Assessment of sleep disturbance is an essential part of the diagnostic criteria used for several psychiatric disorders. Change in sleep patterns over time may indicate response to treatment. In clinical practice, sleep is usually evaluated subjectively by patient self-report. This study was aimed to compare subjective sleep assessment with objective sleep measurement by actigraphy in psychiatric inpatients. Methods：A total of 32 psychiatric inpatients were studied. Patients were asked to wear a wrist actigraphy for three consecutive days and nights and to fill out a sleep log each morning. The severity of depression and anxiety was evaluated according to Beck Depression Inventory and State-Trait Anxiety Inventory on the first day of the study. The subjective level of satisfaction with quality of sleep was also evaluated according to visual analog scale. Nurses assessed sleep at one hour interval between 10:00 PM and 6:00 AM for three consecutive nights. Results：There was statistically significant difference of sleep latency between patient's sleep log and acti-graphic measurement. Nursing reports were more consistent with actigraphic measurement than sleep log. Interestingly, subjectively poor sleepers show no significant difference in sleep parameters compared with those of good sleepers. Subjectively poor sleepers report longer sleep latency than that of actigraphic assessment. The discrepancy between subjective and objective assessment of sleep latency was significantly correlated with scores of Beck Depression Inventory and State-Trait Anxiety Inventory. Conclusion：These results show that there are discrepancies between subjective and objective assessment of sleep. The discrepancy of sleep assessment could be influenced by severe depression and anxiety. Especially objective sleep measurement is needed to assess sleep in psychiatric inpatients with severe depression or anxiety and the subjectively poor sleepers for more reliable measurements.
