Parental Subjective Disaster Experiences and Behavioral Problems in Children Born After the Great East Japan Earthquake
This study examined associations of parents' subjective perceptions of disaster-related harm from the Great East Japan Earthquake (GEJE) with their mental health and with emotional and behavioral problems in their children born post-disaster. Participants included 218 parents (207 mothers, 11 fathers) and 219 children born post-GEJE, residing in affected areas. Parents served as proxy reporters, completing measures assessing their disaster-relate…
Association between caregiving time of young carers and depressive symptoms in emerging adulthood
Young carers (YCs), defined as children or adolescents with substantial caregiving responsibilities for family members, face increased mental health risks, particularly depression. However, the mechanisms underlying this association remain unclear due to limited quantitative research. Emerging adulthood is a psychologically vulnerable period involving key life decisions, when the mental health effects of early caregiving may become more apparent.…
Mediating Effects of Trait Anxiety and State Anxiety on the Effects of Physical Activity on Depressive Symptoms
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
Roles of childhood maltreatment, personality traits, and life stress in the prediction of severe premenstrual symptoms
BACKGROUND: About 3% to 8% of women of fertile age are thought to have premenstrual dysphoric disorder (PMDD), which is regarded as a serious form of premenstrual syndrome (PMS), although the details of this common condition remain unclear. The aim of this study was to analyze the interrelations of childhood maltreatment, personality traits, and life stress in the etiology of PMS/PMDD. METHODS: A total of 240 adult female volunteers from a commun…
Long Working Hours Indirectly Affect Psychosomatic Stress Responses via Complete Mediation by Irregular Mealtimes and Shortened Sleep Duration
Long working hours do not affect mental health directly; however, shortened sleep duration and irregular mealtimes mediate the effect of long working hours on psychosomatic stress responses and depressive symptoms
Effects of the Interaction between Affective Temperaments and BIS/BAS on Depressive Symptoms in Individuals with Major Depressive Disorder
Depressive symptoms (DepS) associated with major depressive disorder (MDD) are influenced by affective temperaments (ATs), behavioral inhibition system (BIS), and behavioral activation system (BAS). However, the effect of interactions between ATs and BIS/BAS on DepS in MDD remains poorly understood. Herein, we aimed to investigate the effects of these interactions. The Temperament Evaluation of Memphis, Pisa, Paris, and San Diego Auto-questionnai…
Cognitive complaints mediate the influence of sleep disturbance and state anxiety on subjective well-being and ill-being in adult community volunteers
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
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
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…
Mediating Roles of Cognitive Complaints on Relationships between Insomnia, State Anxiety, and Presenteeism in Japanese Adult Workers
Complaints of cognitive functions (CCFs), defined as subjective cognitive dysfunction, affect social function; additionally, for workers, this condition is an important factor in presenteeism and mediates the effect of depressive symptoms on presenteeism. This study aimed to investigate whether CCFs mediate the relationships among insomnia, state anxiety (SA), and presenteeism. Participants were 471 Japanese adult workers evaluated using the Athe…
Personality traits mediate the association between perceived parental bonding and well-being in adult volunteers from the community
BACKGROUND: Previous studies reported that subjective well-being in adulthood correlates with perceived parental bonding in childhood as well as personality traits. However, whether personality traits mediate the effect of perceived parental bonding on well-being or not has not been reported to date. In this study, we hypothesized that 'parental care and overprotection' in childhood affect 'well-being' in adulthood through various 'personality tr…
Associations between the depressive symptoms, subjective cognitive function, and presenteeism of Japanese adult workers
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
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
