Identification of risk- and preventive factors predicting child maltreatment in pregnant women with psychosocial problems
Family support, particularly from the maternal grandmother, plays a crucial role in enhancing parenting skills of women with psychosocial difficulties. Assessing these factors and integrating them into public support initiatives could contribute to the prevention of child maltreatment
An international comparison study between public opinion in the UK and Japan regarding capital punishment and the use of an insanity defense
An international comparison e-survey was done regarding public opinions toward capital punishment and insanity defense. • Japanese citizens are affirmative to capital punishment compared to the UK citizen while the majority of both are. • Insanity defense are hardly acceptable in Japan, because of cultural background. Capital punishment represents a pivotal approach to addressing crimes. Although numerous nations, including the UK, have abolished…
Association of SLC6A3 variants with treatment-resistant schizophrenia
The overall results suggest that ( i ) SLC6A3 could be involved in responsiveness to antipsychotic medication and ( ii ) genetic variants modulating brain DA levels may be related to the classification of TRS and non-TRS
A pilot trial of an online guided self-help cognitive behavioral therapy program for bulimia nervosa and binge eating disorder in Japanese patients
BACKGROUND: The purpose of this study was to develop an internet-based Guided Self-Help CBT (iGSH-CBT) for Bulimia Nervosa (BN) / Binge Eating Disorder (BED) for Japanese patients and to test its feasibility. METHODS: A single-arm feasibility study. After baseline assessment, patients underwent a 16-week iGSH-CBT program, our Japanese adaption of the European-based Salut BN program. During the treatment period, weekly email support from trained c…
Identifying factors associated with criminal responsibility by analyzing court trial verdicts
The criminal responsibility of offenders with mental disorders is a key issue in forensic psychiatry. Japan's implementation of the Medical Treatment and Supervision Act and Lay Judge Act in the early 2000s raised public awareness of this issue. To determine how criminal court judges in Japan assess the criminal responsibility of offenders, we examined 453 district court verdicts that mention psychiatric evidence. We extracted elements from each …
Patterns in Psychiatrists’ Prescription of Valproate for Female Patients of Childbearing Age With Bipolar Disorder in Japan
Most psychiatrists frequently or sometimes prescribe valproate for women of childbearing age in Japan
White Matter Features Associated With Autistic Traits in Obsessive-Compulsive Disorder
Obsessive-compulsive disorder (OCD) is among the most debilitating psychiatric disorders. Comorbid autism spectrum disorder (ASD) or autistic traits may impair treatment response in OCD. To identify possible neurostructural deficits underlying autistic traits, we performed white matter tractography on diffusion tensor images (DTI) and assessed autistic trait severity using the Autism-Spectrum Quotient (AQ) in 33 OCD patients. Correlations between…
Psychological Distress Symptoms Associated With Life Events in Patients With Bipolar Disorder
Stressful life events, although less serious than traumatic experiences, affect the clinical course of patients with bipolar disorder. We previously found that bipolarity in patients with major depression is related to the severity of psychological distress symptoms associated with onset-related events. Here, we investigated whether, and to what extent, bipolar patients perceive stressful events as psychological distress symptoms, specifically, i…
Increased Subjective Distaste and Altered Insula Activity to Umami Tastant in Patients with Bulimia Nervosa
The aim of this study was to examine differences in brain neural activation in response to monosodium glutamate (MSG), the representative component of umami, between patients with bulimia nervosa (BN) and healthy women (HW) controls. We analyzed brain activity after ingestion of an MSG solution using functional magnetic resonance imaging (fMRI) in a group of women with BN ( n = 18) and a group of HW participants ( n = 18). Both groups also provid…
Cognitive-Behavioral Therapy for Obsessive–Compulsive Disorder with and without Autism Spectrum Disorder
Cognitive behavioral therapy (CBT) is an effective treatment for obsessive-compulsive disorder (OCD) and is also applicable to patients with both OCD and autism spectrum disorder (ASD). However, previous studies have reported that CBT for patients with both OCD and ASD might be less effective than for patients with OCD alone. In addition, there is no evidence as to why autistic traits might be risk factors. Therefore, we investigated whether como…
How parents suspected of child maltreatment change their cognition and behavior
Although considerable efforts have been made to improve relationships between professionals and parents suspected of child maltreatment, little research has been conducted to examine the ways in which parents escalate their negative cognition and behavior involving professionals. This study developed a model of parents' negative reinforcement of their cognitive behavior and the factors influencing reductions in this reinforcement. Interview data …
