Objective : The reliability and validity of the Korean version of the Patient Health Questionnaire-9 (PHQ- 9) was examined in Korean patients with depressive symptoms. Methods : Eighty six outpatients diagnosed as major depressive disorder or depressive episode of bipolar I disorder according to the DSM-IV criteria were assessed with the PHQ-9, Hamilton Depression Rating Scale (HDRS), the Quick Inventory of Depressive Symptomatology Self Report (QIDS-SR), and the Center for Epidemiologic Studies Depression Scale (CES-D). Results : The Cronbach's alpha coefficient from the PHQ-9 was 0.81. And the correlations of each item with the total score were statistically significant (r=0.28-0.70, p<0.01). The test-retest correlation coefficient (r=0.89, p<0.01) was relatively high and correlations of the PHQ-9 with the HDRS, QIDS-SR and CES-D were 0.70, 0.81, and 0.81 respectively. Conclusion : These results demonstrated that the Korean version of PHQ-9 could be a reliable and valid tool for the screening and assessment of depressive patients. The Korean version of PHQ-9 will be a useful tool for screening depressive symptoms in Korea.

Objectives The purpose of this study was to examine the differences according to depressive symptom-related difficulty status. Methods 2828 participants were a divided into depressive symptom-related difficulty group (difficult group, n = 774), and a non-depressive symptom-related difficulty group (not difficult group, n = 2054). The psychological character of the participants were assessed using the Korean version of the Patient Health Questionnaire-9 (PHQ-9), Satisfaction with Life Scale (SWLS), the 12-item General Health Questionnaire (GHQ-12), and Conner-Davidson Resilience Scale (CD-RISC). Statistical analyses were done using t-test, chi-square, and analysis of covariance (ANCOVA). Results Compared with the no difficulty group, the difficulty group reported significantly higher score in all items of PHQ-9. The score of "feeling tired" was the highest and the score of "suicidal ideation" is the lowest in both groups. ANCOVA analysis that is adjusted with the total score of PHQ-9 showed the differences in SWLS, GHQ-12, and CD-RISC scores between the difficulty group and the no difficulty group. Conclusions The findings suggest that there are different characters on PHQ-9, SWLS, GHQ-12, and CD-RISC according to depressive symptom-related difficulty. Therefore, it is required not only to evaluate depressive symptoms in patients with depression, but also the depressive symptom-related difficulty to understand these differences.

Objectives The purpose of this study was to investigate the relationships among circadian types, depressive mood and internet addiction and to identify the mediating effect of depressive mood between circadian types and internet addiction in Korean College Students. Methods A total of 2632 participants completed questionnaires, which included the Korean translation of the Composite Scale of Morningness (CSM), the Patient Health Questionnaire (PHQ-9), and the Korean version of the Internet Addiction Test (KIAT). Statistical analyses were done using correlation analysis, analysis of covariance and multiple linear regression. Results The CSM score was negatively associated with the PHQ-9 score (r = -0.226, p < 0.001) and the KIAT score (r = -0.218, p < 0.001). The eveningness group showed higher scores in depressive mood and internet addiction than the morningness group (p < 0.001). Depressive mood showed a partial mediating effect between circadian types and internet addiction (${\beta}=0.255$, p < 0.001). Conclusions Internet addiction was associated with circadian types and depressive mood. These results suggest that depression and circadian rhythm management would contribute to the prevention of internet addiction.

Objectives: The purpose of this study was to examine the association between depression and poor oral health in Korean elderly using Korean version of the Patient Health Questionnaire-9 (PHQ-9) for assessment of depressive symptoms. Methods: This study used the data from Korean National Health and Nutrition Examination Survey (KNHANES VI-2). The study included 1,454 elderly Korean aged over 65. Variables included demographic characteristics (gender, age), socioeconomic factor (income, education), systemic diseases, oral health related factor (tooth brush, dental products), health related factor (alcohol drinking, smoking), and depression. Logistic regression analysis was used as sequential models. Effects were quantified as odds ratios (OR) and 95% confidence intervals (CI). Results: From frequency analysis, being female, primary school or less, non-alcohol drinking, poor oral health were significantly related to depression. In the multiple logistic regression model, depression was significantly associated with poor oral health (OR=1.96, CI=1.15-3.53) after adjustment for other covariates including demographic characteristics, socioeconomic factor, systemic diseases, oral health related factor, and health related factor (OR=1.91, CI=1.13-3.27). Conclusions: Depression had an influence on the poor oral health after adjustment as confounding variable in the elderly. It should be focused on the health promotion for the elderly vulnerable to depression and poor oral health. The development of the mental health and oral health should be established.

This study was conducted from April 2020 to June of the same year to identify the working skills, quality of life and depression on occupational therapists working at medical institutions in Gwangju, Jeollabuk-do and Jeollanam-do. Each function was evaluated using the WAI(Work Ability Index), the Korean version of WHOQOL and PHQ-9(Patient Health Questionnaire-9 Korean version) to evaluate the working ability, quality of life and depression level of depression. Studies have shown mo statistically significant differences in all areas of work capability, quality of life, or depression, depending on general characteristics. The correlation between work tretment worker's work ability, quality of life and depression showed a positive correlation between work ability and quality of life and a strong nehative correlation between quality of life and depression. This is a tesult of improved working ability, which improves the quality of life and lowers the level of depression if there is a positive change in the quality of life. It is hoped that research will be conducted considering the work ability and quality of life of occupational therapists who play an important role in rehabilitation and ways to reduce depression.

Objectives : Type D personality was originally introduced to study the role of personality in predicting outcomes of heart disease. However, researches showed that other medical conditions are also affected by this personality. The purpose of this study was to evaluate the relationship between type D personality and somatic symptom complaints in depressive patients. Methods : Eighty-two individuals diagnosed with depressive disorder were included. Type D personality was measured with DS14. Patient Health Questionnaire(PHQ) 9 and 15 were used to measure depression severity and somatization tendencies. For alexithymia, TAS-20 was used. Student T-test and linear regression analysis were performed. The best regression model was determined by stepwise variable selection. Results : More than half of the subjects(56%) complained at least medium degree somatic symptoms according to PHQ-15 criteria. Two-thirds of the subjects were classified as Type D personality(63.4%). The mean PHQ-15 score of the Type D individuals was significantly higher than the remaining subjects(PHQ-15 mean=12.7, $p=8.2{\times}10^{-7}$). The best regression model included age, PHQ-9 score and NA subscale score as predictor variables. Among these, only the coefficients of age($p=1.5{\times}10^{-3}$) and NA score($p=1.5{\times}10^{-7}$) were found to be statistically significant. Conclusions : The result showed that Type D personality was one of the strong predictors of somatic complaints among depressive individuals. The finding that negative affectivity rather than social inhibition was more closely associated with somatization tendencies does not fully agree with the traditional explanation that inability to express negative emotion predispose the individuals to somatic symptoms. The finding that alexithymia was not shown to be a significant predictors also substantiated this discrepancy. However, it might be possible that the high correlation between NA and SI subscore(r=0.65) and between NA and TAS-20 score(r=0.44) hid the additional effects of social inhibition and alexithymia. Further research with a larger sample would be needed to investigate the effects of the latter two components over and above the effect of negative affectivity on the somatic complaints in depressive patients.

Purpose : This study examined the effect of a home visit cognitive training program that uses a tablet-based digital recognition rehabilitation application, Brain Doctor, on local elderly people's cognitive function and depression. Methods : This study featured 20 elderly people living in Busan Metropolitan City, South Korea, who received a voucher for a home visit service to prevent dementia. The subjects were evenly divided into an intervention group provided with Brain Doctor and a control group provided with a conventional cognitive training program. Korean version of Mini Mental State Examination (MMSE-K) and Korean version of Montreal Cognitive Assessment (K-MoCA) were used to assess cognitive function in each group. Patient Health Questionnaire-9 (PHQ-9) was used to evaluate the depression levels. Results : The intervention group showed a significant change in cognitive function and depression after the intervention (p<.05). There was a statistically significant change in cognitive function and depression between the intervention and control groups (p<.05). Conclusion : This study confirmed that Brain Doctor had a positive effect on the cognitive function and depression of elderly people in the local community. It is expected to become a useful home visit program for dementia prevention in the future.

Objectives : The purpose of this study was to investigate the characteristics of psychosocial factors related to functional dyspepsia(FD) and their effects on quality of life(QOL) in firefighters. Methods : This study examined data collected from 1,217 firefighters. We measured psychological symptoms by Patient Health Questionnaire-9(PHQ-9), Generalized Anxiety Disorder questionnaire(GAD-7), Korean Occupational Stress Scale(KOSS), Ways of Coping checklist(WCCL), Rosenberg's Self-Esteem Scale(RSES) and World Health Organization Quality of Life Scale abbreviated version(WHOQOL-BREF). Chi-square test, independent t-test, Pearson's correlation test, logistic regression analysis, and hierarchical regression analysis were used as statistical analysis methods. Results : For the group with FD, the male participants showed significantly higher frequency(p=0.006) compared to the female participants. The group with FD had higher scores for depressive symptoms(p<.001), anxiety (p<.001), and occupational stress(p<.001), and did lower scores for self-esteem(p=.008), quality of life(p<.001) than those without FD. The FD risk was higher in the following KOSS subcategories: job demand(OR 1.94, 95% CI : 1.29-2.93), lack of reward(OR 2.47, 95% CI : 1.61-3.81), and occupational climate(OR 1.51, 95% CI : 1.01-2.24). In the hierarchical regression analysis, QOL was best predicted by depressive symptoms, self-esteem, and occupational stress. Three predictive variables above accounts for 42.0% variance explained of total variance. Conclusions : The psychosocial factors showed significant effects on FD, and predictive variables for QOL were identified based on regression analysis. The results suggest that the psychiatric approach should be accompanied with medical approach in future FD assessment.

Objectives : This study aimed to explore the association between depression and perceived stress, viral anxiety, reassurance-seeking behavior, and poor sleep quality among the general population in Bangladesh, with self-efficacy as a possible mediator. Methods : Data on stress and anxiety during the pandemic in Bangladesh were collected through an online survey from September 16, 2021 to October 4, 2021. Viral anxiety and depression were measured using the Bangla version of Stress and Anxiety to Viral Epidemic-6 (SAVE-6) and Patient Health Questionnaire-9 (PHQ-9), respectively. Self-efficacy was measured by the General Self-efficacy (GSE) scale. Reassurance-seeking behavior related to the coronavirus disease 2019 infection was measured by the Coronavirus Reassurance-Seeking Behaviors Scale (CRBS). Results : The CRBS showed a significant correlation with SAVE-6 (r=0.281, p<0.001) and PHQ-9 (r=0.227, p<0.001). People with higher anxiety, reassurance-seeking behavior, and poor sleep quality had lower self-efficacy, which led to depression. In contrast, perceived stress increased self-efficacy. The psychological factors impacted depression directly as well as indirectly, and self-efficacy mediated the association. Conclusions : Viral anxiety, reassurance-seeking behavior, perceived stress, and poor sleep quality have a close correlation with depression both directly and indirectly. Self-efficacy can be a mediating factor in the association between psychological distress and depression. Viral anxiety, reassurance-seeking behavior, and poor sleep quality reduce self-efficacy. On the other hand, perceived stress can strengthen self-efficacy.
