OBJECTIVES: The purpose of this study to examine if the levels of anxiety(emotional, cognitive, and behavioral measures) during performance are influenced by interaction of both achievement related self discrepancy(=psychological vulnerability variable) and evaluative threat stress(=stressor) based on vulnerabilitystress model in order to identify the mechanism of development of performance anxiety and furthermore to suggest psychological intervention strategies to reduce and prevent it effectively. METHOD: High and low self discrepancy subjects consisted of students from the upper(n=40) and lower 15%(n=40) on achievement related self discrepancy scale, respectively. They were randomly assigned to either evaluative threat condition or neutral condition, and then all subjects took intellective task(verbal reasoning test and digit symbol test). RESULTS: The results were as follows; 1) High self discrepancy subjects under evaluative threat reported significantly higher level of state anxiety during performance than low self discrepancy subjects under any condition and also experienced higher degreee of state anxiety with marginal significance than high self discrepancy subjects under neutral condition, whereas there were no significant effects on the anxiety level of group variable under neutral condition or of stress variable in low self discrepancy subjects. 2) High self discrepancy subjects reported more cognitive interference during performance than low self discrepancy subjects regardless of the level of stress. 3) High self discrepancy subjects performed marginally significantly more poorly in digit symbol test than low self discrepancy subjects regardless of the level of stress, whereas there were no significant effects on verbal reasoning test. CONCLUSION: The hypothesis that performance anxiety could be affected by achievement related self discrepancy and stress, and specially by interaction between self discrepancy and stress was relatively strongly supported by the results on emotional measure of performance anxiety. In addition, this hypothesis received partial support by the results on cognitive and behavioral measures. We might conclude that it is important to consider achievement-related self discrepancy and evaluative threat stress together to understand the mechanism of development of performance anxiety and to reduce or prevent this anxiety effectively.

OBJECTIVE: Several psychological characteristics of medical students were investigated, the relationhip between these characteristics and academic achievement was identified, and futhermore some significant predictors of their academic achievement were explored. METHOD: Subjects were a total of 489 medical students, 1st, 2nd, 3rd year in Chosun university as of in 1998. We administered self-report questionnaires including age, sex, grade failure, and transfer experience. And Beck Depression Inventory, Achievement Self-Discrepancy Scale, Self-Efficacy Scale, State-Trait Anxiety Inventory(state) Test Anxiety Scale, and the Inventory of Performance Anxiety were handed out to them on April 1998. After the semester, we examined the academic achievement according to grade point average. Pearson's correlations were calculated to explore the relationships between grade failure and other psychological variables, as well as the relationships between academic achievement and other psychological variables. The amount that academic achievement was explained by the psychological variables was obtained using multiple regression analysis. RESULT: 1)In 489 students, grade failure was 168(34.3%) non-failure was 321(65.7%) and transfer was 33(6.7%) 2)While G.P.A., performance anxiety, and self-efficacy, respectively, were negatively correlated with the failure, test anxiety was positively correlated with the grade failure. There were no statistically significant correlations between grade failure and depression, self-discrepancy, or state anxiety. 3)Academic achievement was positively correlated with both gender and self-efficacy, whereas it was negatively correlated with depression, self-discrepancy, test anxiety, and state anxiety, respectively. Female students were better than males in academic achievement. 4)The amount that age, gender, grade failure, transfer, depression, self-discrepancy, test anxiety, state anxiety, performance anxiety, and self-efficacy accounted for academic achievement was 10.86% totally. CONCLUSION: Gender, grade failure, and depression in medical students affected their academic achievement significantly.

This study was designed to compare the outcomes between my ocardial infarction' participation and not-participation in cardiac rehabilitation, so explain how participation in cardiac rehabilitation can be a worthwhile intervention that facilitates recovery from MI. B furthermore this research is intended to provide the fundamental backgrounds in developing cardiac rehabilitation program that can help to improve the patients' the quality of life. A total of 80 out-patients were selected as subject to data collection from April 1th to May 10 1996. The rehabilitated group, consisting of the 40 out-patients had participated with the non-rehabilitation group of 40 out-patients had received usual care during hospitalization. The tools for this study were state-anxiety scale devised by Spielberger(1976) performance health behavior scale developed by Lee(1992) and quality of life scale producted by McGirr(1990). The data were analyzed by use of chi test, ANCOVA, t-test, ANOVA, Pearson's correlation and simple regression using the SPSS program. The study was concluded as follows : 1. Hypothesis 1 : that "the rehabilitation group's anxiety was lower than the non-rehabilitation group's was accepted(t=-2.60, p=0.011). 2. Hypothesis 2 : that "the rehabilitation group's level of performance health behavior was higher than the non-rehabilitation group's" was accepted(t=6.39, p=0.000). 3. Hypothesis 3 : that "the rehabilitation group's quality of life was higher than the non-rehabilitation group's was accepted(t=2.73, p=0.008). 4. The correlations between anxiety, performance health behavior and quality of life. The relationship between anxiety and performance health behavior revealed a significant correlation(r=-.4433, p<.05). And the relationship between anxiety and quality of life revealed a significant correlation(r=-.7679, p<.05), the relationship between performance health behavior and quality of life revealed a significant correlation(r=3934, p<.05). As a result, it was found that the cardiac rehabilitation groups' anxiety was lower than the non-rehabilitation group's, the rehabilitation group' level of performance health behavior was higher than the non-rehabilitation group's. And the rehabilitation group's quality of life was higher than the non-rehabilitation group's. Therefore this study explained how participation in cardiac rehabilitation can be a worthwhile intervention that facilitates recovery from MI.

OBJECTIVES: The purpose of this study was to evaluate anti-depressive effects of exercise on child and adolescent and its association with brain derived neurotrophic factor (BDNF). METHODS: Twenty nine middle school boys (age 13.3±0.7) were divided into two groups, 15 boys for control group and 14 in the experimental group. The control group participated in a regular exercise program, 3 times a week for 15 weeks. During the same period, the experimental group participated in an aerobic exercise program specifically designed to enhance anti-depressive effect of exercise. Serum BDNF level and its performance of each group on the Beck Depression Index (BDI), Children's Depression Inventory (CDI), Screen for Child Anxiety Related Emotional Disorders (SCARED), Aggression Questionnaire (AK-Q), and Stroop task were compared before and after the exercise program. RESULTS: Scores of BDI, CDI, SCARED, and AK-Q were significantly lower in both groups after the exercise programs compared to those before the programs. The Stroop task performances were significantly improved after the programs. However, there were no significant differences between two exercise programs, except SCARED separation anxiety, AK-Q physical, and verbal aggression scores. Also, no association was found between serum BDNF level and anti-depressive effects of exercise. CONCLUSION: Our preliminary results suggest a possible effect of exercise on depression, anxiety, aggression, and cognition of child and adolescents.

INTRODUCTION: Sleep has numerous important physiological and cognitive functions that may be particularly important to elite athletes. Sleep deprivation can have significant effects on athletic performance. However, there are few published data related to the amount of sleep obtained by elite athletes. We investigated sleep patterns of Korean women golfers using sleep-related questionnaires. METHODS: For this study, 98 Korean university women golfers and 46 age- and sex-matched controls were recruited. All subjects were asked to complete the self-administered sleep questionnaire consisting of questions about habitual sleep patterns (sleep onset time, sleep latency, awakening time in the morning, day time napping time), exercise habits, Epworth Sleepiness Scale (ESS), Insomnia Severity Index (ISS), Pittsburgh Sleep Quality Index (PSQI), validation of the Perceived Stress Scale (PSS), and Beck Anxiety Inventory (BAI). RESULTS: The sleep onset time was significantly earlier (pm 23 : 05 +/- 00 : 52 and 00 : 14 +/- 00 : 51 ; t = 5.287, p < 0.001), the waking time was later (am 07 : 21 +/- 01 : 09 and 6 : 35 +/- 00 : 32; t = -2.715, p = 0.008), the weekday total sleep time was greater (417.77 +/- 78.18 minute and 351.52 +/- 77.83 minute ; t = 4.406, p = 0.001), and the daytime nap time was greater (77.73 +/- 41.28 minute and 20.22 +/- 33.03 minute ; t = 7.623, p < 0.001) in the golf athletes compared to the controls. The PSQI scores were significantly lower, but estimated sleep latency and ESS, ISS, PSS, and BAI scores were not different among the two groups. CONCLUSION: This study suggests that Korean university women golfers have good sleep patterns resulting in no difference in sleep-related stress compared to age- and sex-matched control students.

Objectives : Depression is a common psychiatric disorder in cancer patients. The Brief Edinburgh Depression Scale(BEDS), which is an abbreviated version of the Edinburgh Depression Scale, may serve as a useful tool in screening for the depression in patients with the medical illnesses. This report investigated the reliability and validity of the Korean Version of the BEDS(K-BEDS) for the depression in cancer patients. METHODS : One-hundred cancer patients were enrolled in this study. All subjects completed the K-BEDS, the Hospital Anxiety Depression Scale(HADS), and the Karnofsky Performance Status Scale(KPSS). Reliability, validity and Receiver Operating Characteristic(ROC) curve analysis measures were assessed. RESULTS : The K-BEDS showed good internal consistency(Cronbach alpha=0.77) and test-retest reliability(0.94, p<0.001). All item-total correlations were above 0.3. Also, it revealed moderate correlation with the depression subscale of the HADS(r=0.617), but no correlation with the KPSS. Exploratory factor analysis produced only one factor, accounting for 47.1% of the total variance. The most valid cutoff value to screen for depression was a total score of 5 on the K-BEDS, which showed sensitivity of 62.5% and specificity of 86.4% with a positive predictive value of 4.60 and a negative predictive value of 0.43. CONCLUSION : The present findings suggested that the K-BEDS would have good psychometric properties to screen for the depression in cancer patients.

Etifoxine (etafenoxine, Stresam(R)) is a non-benzodiazepine anxiolytic with an anticonvulsant effect. It was developed in the 1960s for anxiety disorders and is currently being studied for its ability to promote peripheral nerve healing and to treat chemotherapy-induced pain. In addition to being mediated by GABA(A)alpha2 receptors like benzodiazepines, etifoxine appears to produce anxiolytic effects directly by binding to beta2 or beta3 subunits of the GABA(A) receptor complex. It also modulates GABA(A) receptors indirectly via stimulation of neurosteroid production after etifoxine binds to the 18 kDa translocator protein (TSPO) of the outer mitochondrial membrane in the central and peripheral nervous systems, previously known as the peripheral benzodiazepine receptor (PBR). Therefore, the effects of etifoxine are not completely reversed by the benzodiazepine antagonist flumazenil. Etifoxine is used for various emotional and bodily reactions followed by anxiety. It is contraindicated in situations such as shock, severely impaired liver or kidney function, and severe respiratory failure. The average dosage is 150 mg per day for no more than 12 weeks. The most common adverse effect is drowsiness at the initial stage. It does not usually cause any withdrawal syndromes. In conclusion, etifoxine shows less adverse effects of anterograde amnesia, sedation, impaired psychomotor performance, and withdrawal syndromes than those of benzodiazepines. It potentiates GABA(A) receptor-function by a direct allosteric effect and by an indirect mechanism involving the activation of TSPO. It seems promising that non-benzodiazepine anxiolytics including etifoxine will replenish shortcomings of benzodiazepines and selective serotonin reuptake inhibitors according to animated studies related to TSPO.

OBJECTIVES: In addition to the main symptoms of posttraumatic stress disorder (PTSD), which include reexperience, avoidance and hyperarousal, many patients complain of cognitive deficits and especially in attention and memory. This study was conducted to evaluate the cognitive deficits of survivors of a tragic shooting incident at a frontline guard post. All of the survivors experienced the same accident, and they were homogeneous in terms of age and education level, which are closely associated with cognitive performance. METHODS: We recruited 12 survivors who suffered from PTSD following the same traumatic incident and we also recruited 12 normal volunteers, and we assessed their neurocognitive functions with using a vigilance test, a continuous attention test, a reaction unit test and the Corsi block tapping test in the computerized Vienna Test System, as well as an auditory verbal learning test and complex figure test in the Rey-Kim Memory Test. Standardized clinical scales, including the Clinician-Administered PTSD Scale, the Hamilton Depression Rating Scale, the Hamilton Anxiety Scale and the State-Trait Anxiety Scale I and II, were used to assess the involved mental areas and the severity of the PTSD symptoms. RESULTS: The patient group showed significant impairments in continuous attention, and the visual and auditory information processing time on the Vienna test when compared to the control group. The patient group also showed significant impairments in the verbal memory, visual memory and visuospatial function on the Rey-Kim Memory Test. CONCLUSION: In this study, the author reports on the cognitive impairments in patients with PTSD as measured by computerized neurocognitive tests and memory tests. Future studies are needed to determine the changes in cognitive functioning that are related to symptom improvement, as well as the influence of the therapeutic effects on the cognitive improvement.

PURPOSE: Psychiatric problem such as depression and anxiety is prevalent and is associated with morbidity and mortality in hemodialysis patients. But it is difficult to assess and is undertreated. The aim of this study is investigating the prevalence and the risk factors for depression and anxiety among patients receiving maintenance hemodialysis. METHODS: We used the Hospital Anxiety and Depression scale (HADS. Korean version) as a screening test for 104 hemodialysis patients in a single center. Univariate analysis and mutltivariable logistic regression analysis were used to evaluate the association between the psychiatric problem (depression and anxiety) and other patients' factors (social economic factors and medical conditions). RESULTS: The mean age was 58.2+/-12.1 years and the causes of ESRD were diabetes mellitus (50%), hypertension (27.9%), chronic glomerulonephritis (8.7%), and other or unknown causes (14%). The prevalence of depression was 58.7%, and univariate analysis revealed that comorbidity index, Karnofsky index, serum creatinine, and age were statistically significantly correlated with depression. But Multivariable logistic regression analysis demonstrated that only Karnofsky index was independently associated with depression [odds ratio (OR)=5.834, p=0.007]. The prevalence of anxiety was 27.9% and only karnofsky index was significantly correlated with anxiety on both univariate and multivariable logistic regression analysis. CONCLUSION: Depression and anxiety were prevalent in hemodialysis patients. Poor performance status was highly associated with depression and anxiety.

BACKGROUND: Health risk assessments (HRA) are used by many organisations as a basis for developing relevant and targeted employee health and well-being interventions. However, many HRA's have a western-centric focus and therefore it is unclear whether the results can be directly extrapolated to those from non-western countries. More information regarding the differences in the associations between country status and health risks is needed along with a more global perspective of employee health risk factors and well-being overall. Therefore we aimed to i) quantify and compare associations for a number of health risk factors based on country status, and then ii) explore which characteristics can aid better prediction of well-being levels and in turn workplace productivity globally. METHODS: Online employee HRA data collected from 254 multi-national companies, for the years 2013 through 2016 was analysed (n = 117,274). Multiple linear regression models were fitted, adjusting for age and gender, to quantify associations between country status and health risk factors. Separate regression models were used to assess the prediction of well-being measures related to productivity. RESULTS: On average, the developing countries were comprised of younger individuals with lower obesity rates and markedly higher job satisfaction compared to their developed country counterparts. However, they also reported higher levels of anxiety and depression, a greater number of health risks and lower job effectiveness. Assessment of key factors related to productivity found that region of residency was the biggest predictor of presenteeism and poor pain management was the biggest predictor of absenteeism. CONCLUSIONS: Clear differences in health risks exist between employees from developed and developing countries and these should be considered when addressing well-being and productivity in the global workforce.
