To investigate the cognitive characteristics that affect the emotional and functional distress caused by tinnitus and to decide and test the model to explain their relations, 167 patients with tinnitus, who visited Samsung Medical Center, Seoul, Korea between March 2001 and May 2002 were recruited. To examine their features related to tinnitus, the following scales were administered; Tinnitus-related basic questionnaire including dysfunctional beliefs, Tinnitus Handicap Inventory, State-Trait Anxiety Inventory, Anxious Thought and Tendencies, Self-Consciousness Scale, and modified 'catastrophic thought' from Coping Strategies Questionnaire. The results showed that the duration of experiencing tinnitus was 4.7 +/-7.1 yr, those who com-plained of hearing one sound were the most common (45.5%), and hearing sounds similarly described to whistling were the most common (22.5%). Also, there were significant correlations among tinnitus features, cognitive characteristics, and distresses from tinnitus. As a result of testing the model, Normed fit index, Incremental fit index, Tucker-Lewis index, and Comparative fit index were over .90, indicating that it is a good model, and Root mean square error of approximation showed a reasonable fit. Also, the direct effects of the trait or severity of tinnitus on distress did not appear to be significant, thus it appeared to be affecting indirectly through the cognitive characteristics. This result shows that cognitive interventions can be important for the psychological adaptations of tinnitus patients.

Although the currently available literature has provided some empirical support for a tripartite model of child and adolescent anxiety and depression, one of the limitations of these studies was that they have been conducted in America, primarily with Caucasians. In order to make this model more applicable to diverse ethnic and cultural groups, this study used a tripartite model for child and adolescent anxiety and depression in Korea, using confirmatory factor analysis with logically selected items from the Revised Children's Manifest Anxiety Scale (RCMAS), as well as the Children's Depression Inventory (CDI). The results indicated that the model fit of a threefactor model was superior to one- and two-factor models. In addition, the findings of discriminant analysis demonstrated that the correct classification rate with three factors of the tripartite model was superior to the classification rate achievable using CDI and RCMAS. In a departure from Clark and Watson's hypothesis, however, the correlations of three factors were significantly higher than had been expected. The results are discussed on the basis of cultural background.

The prevalence of postnatal depression (PND) was reported to be 6.8% in an obstetric setting in Singapore. Since primary care physicians are the healthcare clinicians most likely to interact with postnatal mothers in Singapore, they are in the best position to screen for PND and help new mothers. PND affects the well-being of the mother, her baby and those around her. If left untreated, depression can result in lasting adverse outcomes such as unfavourable parenting practices, impaired mother-infant bonding, impaired intellectual and emotional development of the infant, maternal suicide, and even infanticide. The Edinburgh Postnatal Depression Scale and the Patient Health Questionnaire-2 are effective screening tools that can be easily used in primary care settings for screening at-risk mothers. Herein, we discuss the management options available in primary care settings, as well as share some local resources available to mothers and the benefits of timely intervention.

Depression is an important comorbidity of asthma. However, little information is available about depression and its potential impact on asthma control in Korean adult asthma patients. We aimed to estimate the prevalence and risk factors for depression in Korean adults with persistent asthma. The 127 non-elderly (20-64 yr) and 75 elderly (> or =65 yr) patients with asthma were recruited. Demographic and clinical data were extracted, and the patients completed the Asthma Specific Quality of Life (AQOL) questionnaire and asthma control test (ACT). Depression status was defined using the Korean version of the Patient Health Questionnaire-9 (PHQ-9). Depression was more prevalent in non-elderly (18.9%) than in elderly patients with asthma (13.3%). Patients with depression were significantly younger, had lower economic status, shorter disease duration, poorer asthma control, and worse AQOL scores (P<0.05). Within the non-elderly group, younger age and shorter disease duration were significantly associated with depression (P<0.05). Within the elderly group, a higher body mass index and current smoking status were significantly associated with depression (P<0.05). The PHQ-9 score was significantly correlated with worse ACT and AQOL scores in both groups. In conclusion, depression is strongly associated with poor asthma control and quality of life in Korean adult asthma patients. Our results provide important clues that used to target modifiable factors which contribute to development of depression in asthma patients.

INTRODUCTIONGiven that past research on drinking problems has focused primarily on younger samples, the present study sought to examine the prevalence and correlates of alcohol use among the elderly in Singapore.

MATERIALS AND METHODSData were extracted from the Well-being of the Singapore Elderly (WiSE) study, a cross-sectional, epidemiological survey conducted among a nationally representative sample of Singapore residents (n = 2565) aged 60 years and above. Variables assessed include drinking problems, depression and anxiety symptoms, obesity, smoking status, chronic physical disorders and disability.

RESULTSThe weighted prevalence of drinking problems (CAGE score ≥2) in our sample was 4.2%. Male sex, Indian ethnicity, and being divorced or separated were associated with a significantly higher likelihood of drinking problems. Participants with drinking problems were also more likely to have subthreshold depression. There were no significant differences in disability among those with drinking problems, those without drinking problems and non-drinkers, after adjusting for demographic variables.

CONCLUSIONOur findings contribute to the body of research that indicates an association between drinking problems and depressive symptoms among the elderly. Thus, screening for depressive symptoms in the elderly with drinking problems may be useful in identifying such comorbidities in order to aid treatment planning.

This study was conducted to investigate the association between the chronic obstructive pulmonary disease (COPD) assessment test (CAT) and depression in COPD patients. The Korean versions of the CAT and patient health questionnaire-9 (PHQ-9) were used to assess COPD symptoms and depressive disorder, respectively. In total, 803 patients with COPD were enrolled from 32 hospitals and the prevalence of depression was 23.8%. The CAT score correlated well with the PHQ-9 score (r=0.631; P<0.001) and was significantly associated with the presence of depression (beta+/-standard error, 0.452+/-0.020; P<0.001). There was a tendency toward increasing severity of depression in patients with higher CAT scores. By assessment groups based on the 2011 Global Initiative for Chronic Obstructive Lung Disease guidelines, the prevalence of depression was affected more by current symptoms than by airway limitation. The area under the receiver operating characteristic curve for the CAT was 0.849 for predicting depression, and CAT scores > or =21 had the highest accuracy rate (80.6%). Among the eight CAT items, energy score showed the best correlation and highest power of discrimination. CAT scores are significantly associated with the presence of depression and have good performance for predicting depression in COPD patients.

PURPOSE: Our purpose was to investigate psychological problems and clinical outcomes in children with psychogenic non-epileptic seizures (PNES). MATERIALS AND METHODS: We retrospectively reviewed the data of 25 patients who were diagnosed with PNES between 2006 and 2012. RESULTS: Twenty-five children with PNES, aged 8 to 19 years (mean 13.82), were referred to psychiatrists for psychiatric assessment. On their initial visit, 72% of patients had comorbid psychological problems, including depression, anxiety, conduct disorder, adjustment disorder, Attention Deficit Hyperactivity Disorder, schizophrenia, and bipolar disorder. Among these, depression was the most frequent (36%). Predisposing and triggering factors included familial distress (40%), social distress (24%), and specific events (20%). The following treatment was advised based on the results of the initial psychological assessment: 3 patients regularly visited psychiatric clinic to assess their clinical status without treatment, nine underwent psychotherapy, and 13 received a combination of psychotherapy and psychopharmacological therapy. At the mean follow-up of 31.5 months after diagnosis, 20 patients (80%) were event-free at follow-up, three (12%) showed reduced frequency, and two (8%) experienced persistent symptoms. CONCLUSION: The outcomes of PNES in children are much better than those in adults, despite a high rate of psychological comorbidities.

INTRODUCTIONElevated levels of psychopathology have been described in various groups of obese patients. This study aimed to describe the presence of depressive and binge eating symptoms in patients presented for clinical weight management at a general hospital in Singapore, as well as their health-related quality of life (HRQOL). Correlations between these symptoms and other demographic and clinical variables were also sought.

MATERIALS AND METHODSPatients presented at a clinical weight management programme were asked to complete the Beck Depression Inventory (BDI), Binge Eating Scale (BES) and the Short Form-36 (SF-36). Clinical and demographic data were also collected.

RESULTSOf the group, 17.1% reported moderate or severe binge eating symptoms and 9.7% reported moderate or severe depressive symptoms. HRQOL, mostly in physical health domains, was lower in this sample compared to local norms. Within the group, binge eating and depressive symptoms, but not increasing obesity, predicted poorer HRQOL.

CONCLUSIONSPsychological symptoms are significantly present in patients presented for clinical weight management and these contribute to poorer quality of life. Addressing these symptoms will improve the overall well-beings of these patients and the total benefits gained will exceed the benefits of weight loss per se.

PURPOSE: The aim of this study was to develop and test an explanatory model for sleep disorders in people with cancer. A hypothetical model was constructed on the basis of a review of previous studies, literature, and sleep models, and 10 latent variables were used to construct a hypothetical model. METHODS: Data were collected from April 19 to June 25, 2010, using self-report questionnaires. The sample was 291 outpatients with cancer who visited the oncology cancer center at a university hospital. Collected data were analyzed using SPSS Win 15.0 program for descriptive statistics and correlation analysis and AMOS 7.0 program for covariance structural analysis. RESULTS: It appeared that overall fit index was good as chi2/df=1.162, GFI=.969, AGFI=.944, SRMR=.052, NFI=.881, NNFI=.969, CFI=.980, RMSEA=.024, CN=337 in the modified model. The explanatory power of this model for sleep disorders in people with cancer was 62%. Further, sleep disorders were influenced directly by cancer symptom experience, dysfunctional beliefs and attitudes about sleep, and past sleep pattern. CONCLUSION: Findings suggest that nurses should assess past sleep pattern and consider the development of a comprehensive nursing intervention program to minimize the cancer symptom experience, dysfunctional beliefs and attitudes about sleep, and thus, reduce sleep disorders in people with cancer.

This study investigated gender differences in symptom profiles of major depressive disorder (MDD) in the Korean general population. Data were pooled from the series of nationwide Korean Epidemiologic Catchment Area surveys conducted in 2001, 2006 and 2011, respectively. Of the 18,807 participants, 507 (397 women and 110 men) were diagnosed with MDD within the prior 12 months. In agreement with previous studies, women with MDD appeared to be more vulnerable to experiencing atypical depressive episodes defined as depression with two or more symptoms of fatigue, increased appetite and hypersomnia (P < 0.001). In terms of individual symptoms, female gender was significantly related with higher prevalence of fatigue (P = 0.008), hypersomnia (P = 0.001), noticeable psychomotor retardation (P = 0.029) and suicidal attempts (P = 0.016) with adjustment for birth cohort effect, partner status, and employment status. In the same analysis, men with MDD appeared more vulnerable to decreased libido than women (P = 0.009). This is the first report to demonstrate gender differences in symptomatology of MDD in the general Korean population, and the results are comparable to previous investigations from western societies. Assumingly, the intercultural similarity in female preponderance to atypical depression might reflect the common biological construct underlying the gender difference in mechanism of MDD. In clinical settings, gender differences of MDD should be carefully considered, because these features could be related with treatment response and drug side effects.
