Effects of irritable bowel syndrome and related cognitive-behavioral and occupational stress factors on the productivity and abdominal symptoms of Japanese workers
OBJECTIVES: This longitudinal study aimed to examine the effects of irritable bowel syndrome (IBS) and related cognitive-behavioral and occupational stress factors on the productivity and abdominal symptoms of Japanese workers. METHODS: An online survey was conducted from October 5 to October 20, 2023 (Time 1), targeting workers aged 20–49 years who were not self-employed or business owners and who worked more than 30 h per week. Data from 1,062 …
Work-related problems and the psychosocial characteristics of individuals with irritable bowel syndrome
BACKGROUND: Irritable bowel syndrome (IBS) is a common, functional gastrointestinal disorder. Because IBS often develops and worsens with stress, it requires treatment from both physical and mental perspectives. Recent years have seen increasing reports of its impact on the daily performance and productivity of workers with IBS, leading to sick leaves and lower quality of life. Therefore, this narrative review aimed to summarize the work and psyc…
Change in Alcohol Use during the Prolonged Covid-19 Pandemic and Its Psychosocial Factors
This study investigated changes in alcohol use and its related psychosocial factors during the COVID-19 pandemic in Japan. Two online surveys were completed by participants between 15 and 20 June 2021 (phase 1) and 13 and 30 May 2022 (phase 2). A total of 9614 individuals participated in both phases (46% women, mean age = 50.0 ± 13.1 years) and a repeated three-way analysis of variance and multinomial logistic regression analysis were conducted. …
Validity and reliability of the Japanese versions of cognitive and behavioral scales for irritable bowel syndrome
BACKGROUND: The Cognitive Scale for Functional Bowel Disorders (CS-FBD) and Irritable Bowel Syndrome-Behavioral Responses Questionnaire (IBS-BRQ) are a useful measures to assess cognitive-behavioral aspects in individuals with IBS. This study aimed to confirm the reliability and validity of the Japanese versions of the CS-FBD (CS-FBD-J) and IBS-BRQ (IBS-BRQ-J). METHODS: Participants comprised 192 students and 22 outpatients diagnosed with irritab…
Descriptive review of internet-based cognitive behavior therapy on anxiety-related problems in children under the circumstances of Covid-19
Effects of Electrocardiographic Monitoring Education on Nurses’ Confidence and Psychological Stress
We aimed to investigate the association between nurses' electrocardiographic (ECG) monitoring education and their confidence and psychological stress regarding ECG monitoring. In 2019, a web-based cross-sectional study was conducted among Japanese nurses. A multivariable logistic regression analysis was performed to evaluate the effects of education on nurses' confidence and psychological stress regarding ECG monitoring. In total, 1652 nurses wer…
Cognitive–behavioral therapy for management of mental health and stress-related disorders
Cognitive–behavioral therapy (CBT) helps individuals to eliminate avoidant and safety-seeking behaviors that prevent self-correction of faulty beliefs, thereby facilitating stress management to reduce stress-related disorders and enhance mental health. The present review evaluated the effectiveness of CBT in stressful conditions among clinical and general populations, and identified recent advances in CBT-related techniques. A search of the liter…
Cognitive behavioral treatment for irritable bowel syndrome
Irritable bowel syndrome (IBS) is a gastrointestinal psychosomatic disorder that often develops and worsens with stress. Hence, it is important to treat it from both, its physical and mental aspects. We reviewed recent research on cognitive-behavioral therapy (CBT)—one of the most widely studied psychological treatments for IBS—since it focuses on addressing the cognitions and behaviors associated with IBS symptoms, and combines diverse content, …
Effects of Interoceptive Sensibility on Mental Health during the Coronavirus Disease 2019 Pandemic
The current coronavirus disease 2019 pandemic has been reported to influence interoceptive sensibility. This study focused on adaptive and maladaptive aspects of interoceptive sensibility and examined how each aspect of interoceptive sensibility affects depression, anxiety, and somatization symptoms under the mild lockdown in Japan, which was not enforceable and a non-punitive lockdown. We used data from 10,672 participants who lived in prefectur…
Alcohol Use and Its Related Psychosocial Effects during the Prolonged Covid-19 Pandemic in Japan
We conducted a large-scale survey in the Japanese population, about one year after the initial declaration of the state of emergency, to investigate alcohol use under the prolonged coronavirus disease 2019 (COVID-19) pandemic and its related psychosocial and demographic characteristics. The survey was conducted online between 15 and 20 June 2021. A total of 11,427 participants were included in the analysis (48.5% female, 48.82 ± 13.30 years, rang…

Altered Gamma-Band Activity as a Potential Biomarker for the Recurrence of Major Depressive Disorder
Background: The neurophysiological mechanisms of cognitive reactivity, the primary vulnerability factor of major depressive disorder (MDD) recurrence, remain unclear in individuals with recovered MDD (rMDD). Because gamma-band responses (GBRs) can be used to measure cognitive processing, they may also be useful for elucidating the mechanisms underlying cognitive reactivity. Identifying these mechanisms may permit the development of an index for p…
Effect of prolonged stress on the adrenal hormones of individuals with irritable bowel syndrome
BACKGROUND: The purpose of this study was to investigate the effect of prolonged stress on the salivary adrenal hormones (cortisol, dehydroepiandrosterone [DHEA], DHEA-sulfate [DHEA-S]) of individuals with irritable bowel syndrome (IBS). METHODS: The participants were female college students, including 10 with IBS and 16 without IBS (control group), who were scheduled for a 2-week teaching practice at a kindergarten. Participants were asked to co…
Anger tendency may be associated with duration of illness in panic disorder
BACKGROUND: Several studies have reported an increased tendency towards anger in patients with panic disorder (PD). If this propensity for anger arises from the pathological process of PD, it may be associated with the duration of the illness. The present study therefore examined the relationship between duration of PD and the personality tendency to experience anger in PD patients. METHODS: Participants were 413 patients (132 men and 281 women; …
The effects of attention retraining on depressive mood and cortisol responses to depression‐related stimuli 1
Although it has been reported that attentional bias at an early stage is found in depression, no study has investigated the effects of modification of attentional bias at an early stage on depressive mood and cortisol response to a stressor. Therefore, this study tested the hypotheses that the modification of attentional bias at an early stage would reduce depressive mood and cortisol response. Fifty‐three participants were allocated alternately …
Family Dysfunction Differentially Affects Alcohol and Methamphetamine Dependence
We investigated the differential influence of family dysfunction on alcohol and methamphetamine dependence in Japan using the Addiction Severity Index (ASI), a useful instrument that multilaterally measures the severity of substance dependence. The participants in this study were 321 male patients with alcohol dependence and 68 male patients with methamphetamine dependence. We conducted semi-structured interviews with each patient using the ASI, …
Effect of day-to-day variations in adrenal cortex hormone levels on abdominal symptoms
INTRODUCTION: The hypothalamic-pituitary-adrenal axis is known to be related to abdominal symptoms, and the relationship between abdominal pain and cortisol secretory patterns has been previously investigated using a cross-sectional approach. Here, we investigated the effect of day-to-day variations in salivary cortisol and dehydroepiandrosterone-sulfate levels on abdominal symptoms in healthy individuals. METHODS: Eleven college students (4 male…
Relationship between cognitive appraisals of symptoms and negative mood for subtypes of irritable bowel syndrome
BACKGROUND: The onset and course of irritable bowel syndrome (IBS) are strongly influenced by psychological factors, and treatment often includes cognitive-behavioral therapy. We conducted a study of the relationships between cognitive appraisal of IBS symptoms and negative mood for the subtypes of IBS. METHOD: The participants were 1087 college students who completed a set of questionnaires that included the Rome II Modular Questionnaire, Self-r…
