This study estimated the excess suicidal mortality during the COVID-19 pandemic in Japan. A Poisson regression model was used to assess the association between unemployment rates, expenditure for alcohol, eating out, and suicide, from January 2008 to March 2020. The excess suicidal mortality was assessed by applying the identified model to data fro...
Article
Previous reports have suggested a cross-sectional association between autistic traits and psychotic experiences (PEs) in adolescents. However, while both autistic traits and PEs show sex-related differences, no studies have directly assessed whether such differences exist in the longitudinal association between autistic traits and PEs. Using a popu...

Background The importance of advance care planning for people with dementia has increased during the Coronavirus Disease 2019 Pandemic. However, family caregivers may have concerns about having conversations regarding advance care planning with their loved ones, which may hinder the initiation of such planning. This study investigated family caregi...
Article
Behavioral neuroscience has dealt with short‐term decision making but has not defined either daily or longer‐term life actions. The individual brain interacts with the society/world, but where that point of action is and how it interacts has never been an explicit scientific question. Here, we redefine value as an intrapersonal driver of medium‐ an...
Article
Background: Middle-aged adults may be the ideal target group for dementia-related stigma reduction interventions to encourage the utilization of services among those who may become family caregivers. Neighborhood social cohesion may diminish dementia-related stigma, particularly in terms of perceived public attitudes. The COVID-19 pandemic can fur...

Background Depression is highly prevalent and causes a heavy burden in adolescent life. Being praised for prosocial behavior might be a preventive factor because both being praised and prosocial behavior are protective against depression. Here, we investigated the longitudinal relationship between being praised for prosocial behavior and depressive...

Background Attention-deficit/hyperactivity disorder (ADHD) develops in early childhood and carries lifelong impact, but early identification and intervention ensure optimal clinical outcomes. Prolonged or excessive parenting stress may be a response to infant behavioral differences antecedent to developmental disorders such as ADHD, and therefore r...

Muscular strength, assessed by handgrip, is a risk indicator for psychiatric disorders, including psychosis. However, the biological mechanisms underlying this association remain unclear. Since advanced glycation end products (AGEs) play a key role in skeletal muscle underdevelopment and psychosis, we examined the role of AGEs in the longitudinal a...

Objectives: The neurodevelopmental delay hypothesis may explain the mechanism of nocturnal enuresis (NE), but whether the hypothesis holds in early adolescence remains unknown, considering NE frequency. Therefore, we aimed to identify whether the neurodevelopmental delays in infancy were associated with the frequency of NE in early adolescence. Met...

Purpose During the COVID-19 pandemic, adolescent carers in the UK may have experienced psychological distress due to increased caring burden and loss of a break from their caring role. This study investigated longitudinal association between adolescents’ caring status and mental health outcomes from 2018/2019 to February–March 2021. Methods The pa...

Background: Immigration has been shown to be associated with an increased risk for psychotic experiences, with similar effect sizes for first-generation and second-generation migration (i.e., children whose parents had migrated). However, this association varies by country, and by ethnic group at the within-country level, such that risk is greatest...
Article
Autistic traits are associated with psychotic experiences in adolescence; however, the mechanisms underlying this relationship are not well understood. Prior research indicates that bullying victimization increases the risk of psychotic experiences in general adolescent populations, and autistic youth are at higher risk of being bullied than their...
Article
Background Cross-sectional studies have suggested that the occurrence of psychotic experiences is associated with loneliness in the general adolescent population. However, there has been a scarcity of prospective longitudinal studies on this topic. Methods We investigated the longitudinal association between the presence of psychotic experiences a...

Background: Tokyo, the capital of Japan, is a densely populated city of >13 million people and thus at high risk of epidemic severe acute respiratory coronavirus 2 (SARS-CoV-2) infection. A serologic survey of anti–SARS-CoV-2 IgG would provide valuable data for assessing the city’s SARS-CoV-2 infection status. This cross-sectional study therefore e...

Birth order is a crucial environmental factor for child development. For example, later-born children are relatively unlikely to feel secure due to sibling competition or diluted parental resources. The positive effect of being earlier-born on cognitive intelligence is well-established. However, whether birth order is linked to social behavior rema...

Adolescents with high autistic traits are at increased risk of depression. Despite the importance of seeking help for early intervention, evidence on help-seeking intentions amongst this population is scarce. Using a population-based cohort in Japan, we examined adolescents’ help-seeking intentions and preferences by the level of autistic traits an...
Article
Aim Children with special health care needs (CSHCN) are those who require more care for their physical, developmental, or emotional differences than their typically developing peers. Among a wide range of burdens that caregivers of CSHCN experience, the mental burden of caregivers is still not well investigated. This study aimed at examining the re...

Purpose This paper aims to introduce Seikatsu Rinsho , a values-based approach to supporting recovery based on identifying service user values and aspirations that have been developed since 1958 in Japan where mental health services are still hospital-based and user involvement is not well-developed. This paper believes this will be of great implic...

Brain responses to sight and taste of foods have been examined to provide insights into neural substrates of ingestive behavior. Since the brain response to food images and taste stimuli are overlapped in neural circuits of eating behavior, each food cue would influence eating behavior in a partly similar manner. However, because few studies have e...

Introduction: For assessing personal values, the rating scale method may not adequately reflect the hierarchical structure of personal values and tends to be influenced by response style bias. The paired comparison method is considered a promising alternative approach, because it engages comparative judgment and may reduce response style biases. T...

Aim: The number of cancer patients with dementia has increased markedly in accordance with aging societies. Cancer patients might receive palliative and end-of-life care to maintain their quality of life; however, the impact of dementia on the quality of death is unexamined in this population. Consequently, we explored the impact of dementia on th...
