About the Lab
Professor Bong-Jin Hahm's research lab focuses on mental health disparities, particularly the prevalence, correlates, and treatment of psychiatric disorders in specific populations such as Korean adults, cancer patients, and medical students. The lab investigates psychological distress, depression, and suicidal ideation in clinical and high-stress populations, with an emphasis on screening tools, risk factors, and barriers to care. Research also explores the psychiatric side effects of medical treatments, such as isotretinoin therapy in acne patients, highlighting the intersection of physical and mental health.

15The objective was to estimate the prevalence and correlates of psychiatric disorders in a nationwide sample of Korean adults. Face-to-face interviews were conducted with the Korean version of Composite International Diagnostic Interview 2.1/DSM-IV (N = 6275, response rate 79.8%). The lifetime and 12-month prevalences for all types of DSM-IV disorders were 33.5% and 20.6%, respectively. Those of specific disorders were as follows: 17.2% and 7.1% for alcohol use disorder, 11.2% and 7.4% for nicoti
The distress thermometer (DT), a one-item measure for distress, provides a means for rapidly and effectively screening psychological distress in cancer patients. In this pilot study, a screening efficacy of the DT was investigated in a mixed cohort of 108 Korean cancer patients. Participants completed the DT, the problem list (PL), and the Hospital Anxiety and Depression Scale (HADS), and answered questions regarding supportive needs and their degree of satisfaction with several aspects of care.
This study demonstrated that Korean medical students experience depression frequently. It also highlighted the possible risk factors of MDD among medical students and pervasive association of depression with poor functioning.
Oral isotretinoin is a highly effective agent for the treatment of moderate to severe acne, but ever since oral isotretinoin was introduced as a modality for acne, the relationship between oral isotretinoin therapy and psychiatric problems, especially depression, has been controversial. The purposes of this study were to know the acute effects of oral isotretinoin therapy on psychiatric symptoms and to investigate the relationships among them, which have not been reported in the published work.
OBJECTIVES: Depression is more frequently experienced and induces more severe consequences in medical students than in the general population. However, treatment rates for depression in medical students are still low. In this study, the authors investigated factors that affect treatment for depression and dispositions towards treating depression among South Korean medical students. METHODS: A nationwide, cross-sectional survey was administered to medical students attending all 41 medical schools
Despite a relatively high rate of suicide associated with cancer, this issue has not been explored in Korean patients. This study investigates the prevalence and factors related to 'the desire for hastened death' (DHD) in Korean cancer patients. A cross-sectional survey using standardised measures, including the Schedule of Attitudes toward Hastened Death and the Hospital Anxiety and Depression Scale, was performed with 131 patients with different types of cancer. 13.7% of the participants exper
Disruption of circadian rhythms, which frequently occurs during night shift work, may be associated with cancer progression. The effect of chronotype (preference for behaviors such as sleep, work, or exercise to occur at particular times of day, with an associated difference in circadian physiology) and alignment of bedtime (preferred vs. habitual), however, have not yet been studied in the context of cancer progression in women with breast cancer. Chronotype and alignment of actual bedtime with
BACKGROUND: Doctor-patient communication is a crucial aspect of patient care. This study explored the communication experience of patients in a cancer consultation over the course of the cancer continuum. METHODS: In-depth interviews with seven breast cancer patients were carried out. RESULTS: Themes related to communication experiences across the five phases of cancer consultation, from diagnosis to recurrence, were identified. The most salient issue is that patients also perceived cancer as 'a
Depression is related to a higher initial level of DD and its faster rate change which in turn, predicted end-semester fatigue, identifying one of the possible pathways through which depression impacts the functioning and health of affected students.
OBJECTIVE: Risk factors for chemotherapy-induced nausea and vomiting (CINV) include older age, female sex, alcohol consumption, and a history of motion sickness. Although gastrointestinal symptoms are found to be related with sleep and mood in other conditions, little is known about their effects on CINV. METHODS: This prospective observational study recruited patients with early-stage breast cancer who had recovered from surgery before receiving a first cycle of anthracycline and cyclophosphami
