  • Mediating Effects of Trait Anxiety and State Anxiety on the Effects of Physical Activity on Depressive Symptoms

    Open Access•Masayuki Kikkawa, Akiyoshi Shimura et al.•ARTICLE•International Journal of…•2023

    The present study suggests that an optimal physical activity time exists for depressive symptoms. The path model demonstrated an association between the three factors of optimal physical activity time, trait anxiety, and depressive symptoms, and the effect was fully mediated by trait anxiety

  • Cognitive complaints mediate the influence of sleep disturbance and state anxiety on subjective well-being and ill-being in adult community volunteers

    Open Access•Kuniyoshi Toyoshima, Masahiko Ichiki et al.•ARTICLE•BMC Public Health•2022

    This study suggests that CCs mediate the associations of sleep disturbance and state anxiety with SWB and SIB, respectively, in adult community volunteers. To address SWB and SIB associated with sleep disturbance and state anxiety, evaluating CCs may be useful in public mental health. Our findings will encourage health care workers to assess CCs more systematically. Future studies may need to target CCs to develop interventions for SWB and SIB

  • Subjective cognitive impairment and presenteeism mediate the associations of rumination with subjective well-being and ill-being in Japanese adult workers from the community

    Open Access•Kuniyoshi Toyoshima, Masahiko Ichiki et al.•ARTICLE•BioPsychoSocial Medicine•2021

    BACKGROUND: In recent years, the roles of rumination, subjective cognitive impairment (SCI), and presenteeism have been emphasized in occupational mental health. However, associations between rumination, SCI, presenteeism, and psychological well-being are not fully understood. We hypothesized that SCI and presenteeism mediate the associations between rumination and subjective well-being (SWB) and subjective ill-being (SIB). Hence, we investigated…

  • Associations of Cognitive Complaints and Depressive Symptoms with Health-Related Quality of Life and Perceived Overall Health in Japanese Adult Volunteers

    Open Access•Kuniyoshi Toyoshima, Takeshi Inoue et al.•ARTICLE•International Journal of…•2021

    Cognitive complaints, defined as perceived cognitive dysfunction in daily living, are associated with depressive symptoms. The associations of cognitive complaints and depressive symptoms with health-related quality of life (HRQoL) and perceived overall health in Japanese adults remains unknown. To investigate these relationships, we evaluated a convenience sample of 525 Japanese adult volunteers (Mage: 41.3 ± 11.7; 238 male and 287 female). We u…

  • Associations between the depressive symptoms, subjective cognitive function, and presenteeism of Japanese adult workers

    Open Access•Kuniyoshi Toyoshima, Takeshi Inoue et al.•ARTICLE•BioPsychoSocial Medicine•2020

    BACKGROUND: Presenteeism has attracted much attention in the research into mental health. However, how cognitive complaints and depressive symptoms affect presenteeism remains unknown. Therefore, this study examined the correlation between subjective cognitive impairment, depressive symptoms, and work limitations. METHODS: We collected data from 477 adult workers in Japan. We evaluated subjective cognitive function using the Cognitive Complaints …

  • Combined Effects of Parenting in Childhood and Resilience on Work Stress in Nonclinical Adult Workers From the Community

    Open Access•Hiroto Sameshima, Akiyoshi Shimura et al.•ARTICLE•Frontiers in Psychiatry•2020

    In this study, we showed that perceived parental bonding affects resilience, and that both factors affect the stress response and perceived job stressors. These findings suggest that parental bonding and resilience are major individual factors affecting work stress, and should be noted when considering industrial hygiene measures for individual workers
