The purpose of this study was to investigate the stress response of nurses working on psychiatric wards (psychiatric nurses) compared with that of nurses working on general wards (general nurses) in order to provide assessment data for intervention of the stress response. The Symptoms of Stress Inventory was used to measure the stress response. Data were collected by a direct survey method using a questionnaire and were collected from March first to March 30, 1995. A sample of 200 nurses working in three psychiatric hospitals and psychiatric wards in four university hospitals in Seoul and Kangwon province were selected and 200 nurses working on general wards from two general hospitals in Seoul were also selected for a total sample of 400 nurses. Nurses who had experienced more than one of the major life events in the last two years were excluded from the total number in the samples, so the final sample was 161 psychiatric nurses, and 169 general nurses. The Scores for the total stress response, scores of the SOS subscales, stress response by sociodemographic characteristics of the nurses working on the psychiatric wards were compared with those of nurses working on the general ward. The results of this investigation are as follows 1. The mean total SOS score for the psychiatric nurse was 0.81 (SD=0.48) and that of the general nurses was 0.90(SD=0.53). 2. The Mean score for peripheral manifestation, con tral-neurological symptoms, gastrointestinal symptoms, muscle tension, habitual patterns, de-pression, anxiety, anger and cognitive disorganization for the general nurses showed a tendency to be higher than those of the psychiatric nurses. Mean score for cardiopulmonary symptoms for the general nurses was significantly higher than that of the psychiatric nurses. 3. The mean scores for the sixteen SOS items for the general nurses was significantly higher than for the psychiatric nurses. The 16 items were flushing of the face, sweating excessively even in cold weather, thumping of the heart, rapid breathing, dry mouth, a choking lump in the throat, hoarseness, muscle tension in hands or arm, muscle tension in leg, working tiring one out completely, severe aches a핀 Pain make it diffi-cult to do the work, severe nervous exhaustion, worrying about health, feeling weak and faint, so upset that one wants to hit something, unable to keep thoughts from running through one's mind. The mean score of only 505 item were significantly higher for the psychiatric nurses. 4. Stress responses between psychiatric nurses and general nurses were significantly different according to the following demographic characteristics : marriage, duration of work, position, accommodation, planning to move into another working site, working ward, education in psychiatric nursing.

Stress involves changes in behavior, autonomic function and the secretion of hormones. Autonomic nervous system (ANS) contributes to physiological adaptive process in short durations. In particular, heart rate variability (HRV) analysis is commonly used as a quantitative marker depicting the ANS activity related to mental stress. The aim of this study is to investigate correlations between psychological responses to stress and HRV indices induced by the cognitive stressor. Thirty-three participants rated their mental and physical symptoms occurred during the past two weeks on Stress Response Inventory (SRI), which is composed of seven stress factors that may influence the status of mental stress levels. Then, they underwent the psychophysiological procedures, which are collected electrocardiogram (ECG) signals during a cognitive stress task. HRV indices, the standard deviation of R-R interval (SDNN), root mean square of successive R-R interval difference (RMSSD) and low frequency (LF)/high frequency (HF) ratio were extracted from ECG signals. Physiological responses were calculated stress responses by subtracting mean of the baseline from the mean of recovery. Stress factors such as tension, aggression, depression, fatigue, and frustration were positively correlated to HRV indices. In particular, aggression had significant positive correlations to SDNN, RMSSD and LF/HF ratio. Increased aggressive responses to stress correlated with the increases of all HRV indices. This means the increased autonomic coactivation. Additionally, tension, depression, fatigue, and frustration were positively associated with RMSSD reflecting increases in parasympathetic activation. The autonomic coactivation may represent an integrated response to specific cognitive reactions such as the orienting response.

The perceived stress response inventory(PSRI) was developed to measure 4 types of current stress responses : emotional, somatic, cognitive, and behavioral responses. 242 patients with psychiatric disorders(71 patients with anxiety disorders, 73 patients with depressive disorders, 47 patients with somatoform disorders, 51 patients with psychosomatic disorders) and 215 healthy subjects completed the questionnaire including the PSRI. Global assessment of recent stress(GARS) scale, perceived stress questionnaire(PSQ) and symptom checklist-90-revised(SCL-90-R) were also administered at the same time. Factor analysis for each of 4 types of stress responses yielded 8 factors : negative emotional responses, general somatic symptoms, specific somatic symptoms, lowered cognitive function and general negative thinking, self-depreciative thinking, impulsive-aggressive thinking, passive-responsive and careless behavior, and impulsive-aggressive behavior. Both test-restest reliability(r= .83 -.93) and internal consistency(Cronbach's alpha : .79 -.96 for each of 8 subscales and .98 for total items of the scale) were all at statistically significant levels. Total scores of the PSRI significantly correlated with total scores of GARS scale, PSQ, and global indicies of SCL-90-R, respectively. The patient group had significantly higher scores than healthy subjects in each of all the subscales except impulsive-aggressive behavior subscale. These results suggest that the PSRI is a reliable and valid tool stable over time which may be effectively used for the research in stress-related field including psychosomatic medicine.

Objectives : Psychological comorbidities are high in patients with obesity and are associated with a variety of medical and dietary problems. This study aims to examine the association between psychological factors and obesity. Methods : This study was performed in pre-menopausal obese($BMI{\geq}25kg/m^2$, waist circumference ${\geq}85cm$) women in Seoul, in 2008 (n=35). Every patient underwent the obesity treatment program. The program included dietary and exercise education, and abdominal mesotherapy for 6 weeks. Simple anthropometry including weight, BMI and Computed Tomography (CT) including Subcutaneous adipose tissue (SAT), Visceral adipose tissue (VAT) and Visceral adipose tissue/Subcutaneous adipose tissue ratio (VSR) were done. To assess psychological factors, the Rosenberg self-esteem scale (SES) questionnaire, Beck depression inventory (BDI) questionnaire and stress response inventory(SRI) questionnaire were administered. Results : 1. All of the obesity indicators (except VSR) decreased significantly after the obesity treatment program. 2. There was a significant relationship between self esteem (SES score) and visceral obesity (VAT and VSR) measured at the end of the program. 3. During the intervention, the more weight, BMI, and subcutaneous adipose tissue decreased, the more self-esteem (SES) increased. There was no relationship between depression (BDI) and obesity. And the change in stress response (SRI) was associated with the change of deep subcutaneous adipose tissue and total abdominal adipose tissue. Conclusions : This study proves that visceral obesity may contribute to low self-esteem, and there is a possibility that the other psychological factors could also be related with obesity in Korean obese women. Individualised antiobesity therapy may be required depending on the patient's psychological characteristics and weight loss could be helpful in order to treat psychological problem in obese patients.

Objective : Eye movement desensitization and reprocessing (EMDR) has been established as an effective treatment for patients with posttraumatic stress disorder (PTSD). However, the literature is unclear as to whether EMDR is effective in the treatment of other psychiatric disorders. The purpose of this study was to evaluate the potential use of EMDR in the treatment of psychiatric disorders other than PTSD by using a clinician's impression of patient response and a subjective symptom evaluation. Methods : Seventeen diagnostically heterogenous patients without PTSD underwent an average of 4.3 sessions of EMDR. Symptom severity was assessed by the Clinical Global Impression-Change Scale (CGIC), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory (STAI), and Symptom Checklist-90- Revised (SCL-90-R) before and after EMDR. Those whose CGI-C scores were 'very much improved' and 'much improved' after EMDR were classified as 'responders.' The patients' before and after treatment scores of symptom severity and group differences were compared. Results : Twelve of the 17 participants (12/17, 71%) were classified as 'responders.' The patients' scores on all of the scales, with the exception of the trait anxiety scale and obsession-compulsion scale of the SCL- 90-R, significantly decreased after treatment. There was no difference in sociodemographic and clinical variables between the responders and non-responders. Conclusion : The results of our study suggest that EMDR can be a promising candidate for the treatment of patients with psychiatric disorders other than PTSD, and thus further controlled studies are needed to determine whether EMDR can be applied to various psychiatric populations.

Purpose: The purpose of this study was to evaluate food carving among hemodialysis patients and to identify factors affecting the food carving. Methods: A descriptive correlational study was conducted. Data were collected from 129 patients receiving hemodialysis between March 15 and April 15, 2017. Measurement instruments included the general food craving questionnaire trait, the center for epidemiological studies-depression scale, and stress response inventory-modified form. The statistical analysis included t-test, analysis of variance, pearson correlation analysis, and stepwise multiple regression analysis. Results: Mean food craving score was $53.00{\pm}12.36$. Food craving was higher in patients younger than 40 years (F=4.36 p=.006) and having occupation (t=2.18 p=.031). Patients receiving hemodialysis demonstrated higher levels of depression ($21.37{\pm}9.62$) and stress ($39.68{\pm}15.95$). Factors influencing food craving were depression (${\beta}=.52$, p<.001), stress (${\beta}=.65$, p<.001), and age 50~59 years old (${\beta}=-.28$, p=.001) and 60~69 years old (${\beta}=-.19$, p=.026), which accounted for 25.6% of total variance. Conclusion: Food craving among hemodialysis patients was influenced by patients' depression, stress and age. Assessment and management of depression and stress needs to be incorporated as a nursing strategy for dietary management for hemodialysis patients.

Objective : The purpose of this study was to develop the Anger Response Scale(ARS), and then to use the scale in clinical practice. Methods First, a preliminary survey was conducted for 123 healthy adults to obtain 16 response items. Second, a preliminary questionnaire was completed by 258 healthy subjects. Third, a comparison was made regarding anger responses among 189 patients(59 with anxiety disorder, 72 with depressive disorder and 58 with somatoform disorder) and 258 healthy subjects. Results : Factor analysis yielded 4 subscales : aggression, irritability, avoidance and anger suppression. Reliability was computed by administering the ARS to 53 healthy subjects during a 2-week interval. Test-retest reliability for 4 subscales and the total score was significantly high, ranging between .53-.71. Cronbach's ${\alpha}$ for 4 subscales ranged between .62-.72, and .76 for the total score. Convergent validity was computed by correlating the 4 subscales and the total score with the total score of Aggression Questionnaire, State-Trait Anger Expression Inventory, anger and aggression subscale of Stress Response Inventory and hostility subscale of Symptom Checklist-90-Revised. The disorder group was significantly higher than normal group in scores of the avoidance and anger suppression subacale. The depressive disorder and somatoform disorder groups scored significantly higher on the avoidance subscale than the normal group. Conclusion : These results indicate that the ARS is highly reliable and valid. In addition, avoidance response is likely to be a characteristic anger response of the depressive disorder and somatoform disorder groups.

The purpose of this study was to investigate the influence of natural landscapes in the context of work environments. The study examined the impact of natural landscapes on urban office workers' stress reduction and cognitive performance, using physiological, psychological, and cognitive measures. One-hundred-twenty urban office workers participated in the experiments. The physiological measures used were GSR (galvanic skin response) and IBI (interbeat interval), and the psychological measure was ZIPERS (Zucherman Inventory of Personal Reactions). Cognitive performance was measured using a mental arithmetic test that had been developed by a pretest. The results from the physiological, psychological, and cognitive measures converged to indicate that the natural landscape had more beneficial effects in relieving both psychological and physiological stress and in enhancing cognitive performance of the of office workers than the city landscape. The results suggest wide applications in the fields of workers' well-being and landscape research. First, the results can provide reliable information for promoting natural landscaping in work places in order to relieve worker stress and enhance cognitive performance. Second, the results provide an example for future empirical landscape research using multiple measurements, such as psychological, physiological, and cognitive tests. Third, they can foster experimental research to investigate the relationship between stress reduction and natural landscapes.

Purpose: The purpose of this study is to investigate the stress response and sleep state of the new patients who visit the hospital for prosthodontic treatment due to tooth loss to make reference to further treatment direction. Materials and methods: Examinations, consultations, and surveys were conducted on 236 patients (94 males, 142 females, and 24-86 years old), who newly registered at the department of prosthodontics at Pusan national university hospital, for 2 years from 2018. The number of remaining teeth, edentulous arch, possibility of mastication, and future prosthetic treatment directions were recorded. The visual analogue scale (VAS), stress response inventory (SRI) and Insomnia severity index (ISI) were used as tools to measure patient's subjective discomfort, stress response, and sleep status. Results: Among the entire prosthodontic patient group, the average value of 'fatigue' was significantly higher among the 7 items of SRI, and the value of 'aggression' was significantly lower (P<.001). There are a significant difference between the edentulous and full dentition in the oral discomfort value measured by VAS (P=.004). In cases where less than 20 teeth remain, mastication is impossible, and patients who are planning treatment with removable prostheses, VAS value and 'depression' and 'fatigue' values in SRI were higher than those in the reverse case (P<.05). The patients showed severe level in VAS value have high value of 'tension', 'somatization', 'depression', 'fatigue'and 'frustration'in SRI than non-serious patients (P<.05). Clinical insomnia occurred in 11.4% of all patients, and women had significantly lower sleep quality than men (P=.044). Patients with insomnia showed significantly higher scores on the VAS value and all 7 SRI items than those of normal sleepers (P<.05). Conclusion: The new prosthetics had high 'fatigue' value among the 7 items of SRI. The oral condition, number of residual teeth and mastication function and clinical insomnia affected oral discomfort and the stress response.

Objectives: This study examined the effect of mood and personality characteristics on psychophysiological responses measured by a biofeedback system in a normal population. Methods: Fifty healthy volunteers without any history of medical or psychiatric illnesses participated in this study. We measured the Spielberger trait anxiety inventory, Beck depression inventory, and Eysenck personality questionnaires in these subjects. Using the J & J biofeedback system, we also measured skin temperature, electrodermal response, forearm and frontal electromyography (EMG)s in 3 experimental conditions of baseline, stress, and recovery phases. Results: Trait anxiety did not show any significant correlation with psychophysiological responses except stress response in forearm EMG levels(r=0.282, p<0.05). Depressed mood was negatively correlated with forearm EMG levels in baseline (r=-0.299, p<0.05) and recovery phases(r=-0.314, p<0.05). Subjects with relatively high levels of depressed mood showed different stress and recovery responses in frontal EMG levels compared with those with relatively low levels of depressed mood (F=4.26, p<0.05). Extroverted subjects showed higher levels of forearm EMG than introverted ones in stress phase. Conclusion: Mood and personality characteristics in healthy subjects are closely related with psychophysiological responses measured by a biofeedback system. We suggest that mood and personality characteristics should be considered as important variables in analyzing abnormal psychophysiological responses in some psychiatric patients.
