Professor Bong-Jin Hahm's research lab focuses on the intersection of mental health and chronic illness, particularly in oncology and dermatology populations. The lab investigates psychological distress, depression, and suicidal ideation in patients with cancer and acne, with an emphasis on screening tools, risk factors, and the impact of psychiatric symptoms on quality of life and disease progression. Research also explores biological and behavioral factors—such as circadian rhythms and chronotype—that may influence mental health outcomes in chronic disease settings.

Abstract 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
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.
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
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.
Poor sleep quality increases risk of CINV in patients with breast cancer. Sleep problems should be assessed and considered in the management of CINV.
Treating psychological distress and enhancing EWB and PWB can be high impact intervention targets throughout the cancer trajectory.
Neoadjuvant chemotherapy, that is, the administration of chemotherapy before surgery, has been commonly used for locally advanced breast cancer to improve the surgical outcomes and increase the opportunity for breast-conserving therapy. Women with breast cancer often receive an anthracycline-based regimen as the neoadjuvant chemotherapy, which is associated with a high risk of emesis. Despite the development of novel antiemetics, chemotherapy-induced nausea and vomiting (CINV) has been commonly
