Objective: As coping strategies can influence the illness course of mood disorder, they could be potential targets for psychological intervention. The current study investigated the similarities and differences in stress coping styles between bipolar disorder (BD) and depressive disorder (DD). Methods: Subjects with BD (n=135) and DD (n=100) who met the DSM-IV diagnostic criteria were included in this analysis. Coping strategies were assessed using the coping inventory for stressful situations and depressive symptoms were assessed by Beck depression inventory. Results: The BD group showed significantly more avoidant and task-oriented coping than the DD group (t=2.714, p=0.007; t=2.193, p=0.039). After excluding the effect of the depressive symptoms themselves (by comparing two groups in non-depressive state), the BD group still showed significantly more avoidant and task-oriented coping than the DD group (t=2.040, p=0.045; t=2.556, p=0.013), but when the symptoms of depression get greater, the difference between BD and DD coping strategies were reduced. Conclusion: Subjects with BD tend to use more task and avoidant coping than DD subjects. But when the symptoms of depression get greater, the difference in coping strategies between BD and DD were reduced.

Objective Face-to-face evaluation is the most important in psychiatric evaluation, but smart healthcare, including non-face-to-face evaluation, can be beneficial considering the situation in which face-to-face evaluation is limited or the preventive aspect of mental illness. In this paper, we aimed to check whether mental health screening tests have the same significance as paper-based tests even when collected through mobile applications.Methods A smart mental healthcare screening test was conducted on the 1,327 community subjects. We measured two indicators of depression (Patient Health Questionnaire 9-item scale, PHQ-9) and anxiety (Generalized Anxiety Disorder 7-item scale, GAD-7) to check mental health conditions.Results The average Cronbach’s alpha value of the PHQ-9 questionnaire was good at 0.870. As a result of PHQ-9’s principal component analysis, one component with an eigenvalue of 1 or more was identified, which is suitable to be described as a single factor. The average Cronbach’s alpha value of the GAD-7 was 0.919. The structural validity of the GAD-7 was confirmed through principal component analysis.Conclusion Our results show that PHQ-9 and GAD-7 scales performed through mobile applications can have the same meaning as paper-based tests. Surveys using a tablet PC, or smartphone application can monitor residents’ mental health and accumulate data. Based on these data, smart mental health management can check the mental health of residents and treat mental illness in connection with medical services.

Background: Personality might be one of the important factors related to stress-coping in mood disorders. This study aimed to investigate the relationship between personality and stress-coping strategies in patients with bipolar and depressive disorders. Methods: A total of 195 patients diagnosed with bipolar and depressive disorders according to the criteria mentioned in Diagnostic and Statistical Manual of Mental disorders’ 5th edition were included. Pearson’s correlation and multiple regression analyses were used to analyze the relationship between personality, measured by Temperament and Character Inventory and NEO-Five Factor Inventory, and coping strategies, measured by Coping Inventory for Stressful Situations. Results: Self-directedness was reported to be positively associated with task-oriented coping in bipolar disorders, and harm avoidance was negatively associated with task-oriented coping in depressive disorders. Beck Depression Inventory score, neuroticism, and extroversion were found to be positively associated with emotion-oriented coping in bipolar disorders, and neuroticism was positively associated with emotion-oriented coping in depressive disorders. Extroversion was reported to be positively associated with avoidance-oriented coping in bipolar disorders, and extroversion, novelty seeking, and reward dependence were positively associated with avoidance-oriented coping in depressive disorders. Conclusion: This study concluded that the relationship between personality and stress-coping strategies may vary based on the type of mood disorder that is diagnosed. The interaction between personality and stress-coping might be considered for the modification of coping strategies in mood disorders.

최근 여성의 사회적 참여와 지위가 상승함에 따라 여성운전자도 급격히 증가해왔다. 이에 주요국에서는 성별 자동차사고 위험도를 분석하고, 성별 위험도 차이의 원인을 규명하려는 연구가 활발히 진행되고 있다. 본 연구는 국내 모든 운전자 중 50만 명을 무작위로 추출하여 성별 자동차사고 위험도를 분석하였다. 종속변수로 사고심도와 사고빈도를 활용하였는데, 사고심도 변수에는 헤크먼모형(Heckman Method)을, 사고빈도 변수에는 일반화선형모형(Generalized Linear Method)을 적용하였다. 분석결과 남성은 교통사고가 발생할 경우 사고피해액이 여성보다 8.3% 높은 것으로 추정되었으며, 반대로 사고빈도의 경우에는 여성의 위험도를 1로 설정할 경우 남성의 위험도는 0.88로 남성의 위험도가 오히려 낮은 것으로 분석되었다. 향후 성별로 상이한 자동차사고 위험도의 원인이 규명된다면 좀 더 실효성 높은 정책을 통해 자동차사고를 경감시킬 수 있을 것이다. Women's roles have changed substantially in economically developed countries; subsequently, the ratio of female drivers has also increased. In such countries, there has been considerable interest in assessing gender differences in vehicle accident risks and reasons to explain the gender differences. This study investigates the gender differences in vehicle accident risk based on 500,000 drivers randomly selected from a population sample. A Heckman model is used for accident damage and a negative binomial model is used for the accident frequency. Empirical results show that male drivers are 8.3% riskier than female drivers in terms of accident damage; however, female drivers are 113% risker than male drivers in term of accident frequency. We can implement more practical policies to reduce vehicle accidents if we can understand the reasons for the gender differences.

Objective Even though the importance of stress-coping, there is no reliable and valid scale to measure the stress-coping behavior yet. The purpose of this study is to explore the psychometric properties of Behavioral Checklist for Coping with Stress (BCCS). Methods A total of 458 subjects including healthy subjects and patients with bipolar or depressive disorders were analyzed. The reliability and validity of BCCS were examined by Chronbach’s alpha and exploratory factor analysis using Principal Component Analysis. In order to evaluate criterion-related validity, the Pearson’s correlation analyses between factors of BCCS and relevant scales were performed. Results BCCS showed good Chronobach’s alpha (0.695-0.833) and had acceptable validity. Factor 1 and factor 4 of BCCS were negatively correlated with depression, anxiety and positivity correlated with task and problem-solving, avoidance, tension-releasing copings in common. Factor 2 and 3 were positively correlated with impulsivity, emotionality, avoidance, behavioral and verbal aggression and tension-releasing copings in common. Different from factor 2, factor 3 was positively correlated with depression, anxiety and anger-suppression. Conclusion The results of this study suggest that this BCCS might be a reliable and valid scale for measuring stress-coping behaviors. This scale could facilitate research to investigate clinical implications related to behavioral stress-coping.

Objective Though anger was highly associated with eveningness in general population, there is no study on the relationship between chronotype and anger-related characteristics in bipolar or depressive disorders. This study aimed to investigate the difference of anger-related characteristics according to chronotypes in bipolar or depressive disorders. Methods Patients with bipolar or depressive disorders (n=238) were included in this study. Their chronotypes and anger-related characteristics were assessed with a self-evaluation of the Composite Scale of Morningness (CSM), the State Trait Anger Expression Inventory (STAXI) and the Anger Coping Scale (ACS). Results The eveningness group in patients with mood disorders showed the highest scores of anger-trait (p<0.001), anger-expression(p=0.002) and anger-in (p<0.001) in STAXI subscales, verbal aggression (p=0.010) in ACS subscales among three groups, but the morningess group showed the lowest scores of these subscales among three groups. However, there were no significant differences in all subscales of the STAXI and ACS according to diagnostic subtypes in the Friedman test. Conclusion The results of this study suggested that eveningness in patients with mood disorders might be related to anger proneness and maladaptive anger coping. To manage anger emotion in the patients with mood disorders, therapeutic interventions to modulate eveningness might be helpful.

Objective It is necessary to identify the mental health types of young women considering the importance of the mental health during the peripartum period. This study aimed to classify the mental health types in a community sample of young women with pre-pregnancy, pregnancy, or the postpartum period.Methods A total of 293 young women during pre-pregnancy, pregnancy, or the postpartum period were included in this study. The clinical characteristics of depression, anxiety, perceived stress, and quality of life were assessed. The clinical characteristics of the subject were classified by cluster analysis and compared by analysis of variance.Results From the cluster analysis, the subjects were classified into three groups. Cluster 1 showed significantly lower depression and anxiety and higher quality of life than those of cluster 2 and 3. Cluster 2 demonstrated significantly higher depression and anxiety and lower quality of life than those of cluster 3 and 1. Cluster 3 represented the intermediate levels between cluster 2 and 1.Conclusion This study suggested that young women during pre-pregnancy, pregnancy, or the postpartum period might be in a good mental health group, a high-risk group requiring active monitoring, or a group in need of treatment. By monitoring mental health, the groups with high risk or requiring treatment could be discovered and proper management for prevention or improvement of mental health and quality of life can be provided.
