Professor Hissei Imai's research lab focuses on mental health and behavioral interventions in medical and community settings, with a strong emphasis on psychological resilience, health promotion, and support systems for healthcare workers and patients. The lab investigates factors influencing mental well-being during public health crises—such as pandemics—and explores how self-efficacy, trust, and perceived protection can improve health behaviors and reduce depression. Key research directions include psychological therapy effectiveness, mental health support for frontline workers, and identifying modifiable factors that enhance patient engagement and social functioning in clinical populations.

Some factors have conflicting effects because they increase both motivation and hesitation. Giving workers the feeling that they are being protected by the national and local government and hospital is especially valuable because it increases their motivation and lowers their hesitation to work.
The future of the novel coronavirus (COVID-19) is still unclear. The outbreak emerged in Wuhan, China in December 2019 and spread to other regions in China, as well as cities in other countries. It is forecasted that outbreaks in major cities globally could be inevitable without large-scale intervention.1 An increasing number of health professionals will encounter infected patients. The medical works in Wuhan are already facing overwhelming pressure, overwork, frustration2 and they need timely m
The evidence in this review was often imprecise. The superiority of either therapy over the other is uncertain due to the low and very low quality of the evidence with regard to short-term efficacy and treatment acceptability, and no data were available regarding adverse effects.The sensitivity analysis and investigation of the sources of heterogeneity indicated three possible influential factors: quality control of psychological therapies, the length of intervention, and the individual modality
The efficacy of azapirones is uncertain due to the lack of meta-analysable data for the primary outcome and low-quality evidence for secondary efficacy outcomes. A small amount of moderate-quality evidence suggested that the acceptability of azapirones for panic disorder was lower than for placebo. However, only trials of one azapirone (namely buspirone) were included in this review; this, combined with the small sample size, limits our conclusions. If further research is to be conducted, studie
We evaluated the associations of risk perception, self-efficacy, and trust with two health promotion behaviors (food habits and exercise) and depressive mood. Diabetic patients aged between 40 and 64 ( n = 1195) were included in the analyses. Risk perception worsened behavioral changes in terms of food habits and depression, whereas self-efficacy and trust improved food habits, exercise, and depression; trust improved exercise and depression. In conclusion, self-efficacy and trust appear to be m
A sizable percentage of community clinic patients experienced Hikikomori. The "current" Hikikomori state corresponded with low clinic attendance and social function; "support from clinical staff" may increase visit regularity; no factors consistently improved social functioning. Further multi-site study is warranted to examine the generalizability of the findings from the current single-center study.

Ipsative imputation appears to be a valid imputation method and can be used to impute data in studies using the 15-item Geriatric Depression Scale, if the percentage of its missing items is 20% or less.
