Trajectory and factors of radiation risk perception of students aged 10-12 years at the time of the Fukushima Daiichi Nuclear Power Station accident.

Various studies have investigated radiation risk perceptions after the accident at the Fukushima Daiichi Nuclear Power Station. However, student surveys are limited. This study aimed to investigate the perception of radiation risk among students aged 18-20 years who were in the 5th and 6th grades of elementary school at the time of the accident. We surveyed students in the Fukushima Prefecture and outside the prefecture. Out of all the data, 59% of the respondents were living in the Fukushima Prefecture at the time of the accident and 41% outside the prefecture. Trajectory analysis showed that changes in anxiety levels over time since 2011 could be divided into five classes: (a) the anxiety was the highest, and this tendency persisted. (b) High at the beginning, but decreased more quickly than class 1. (c) High at the beginning, but it diminished quickly. (d) Not high, but did not diminish easily in later years. (e) Low from the beginning, and persisted. Multinomial logistic analysis showed that among students living outside the prefecture at the time of the accident, a significantly higher proportion was in groups 4 and 5 than in group 2. A significant proportion of boys were present in groups 3, 4 and 5. A significant proportion of students whose current educational institutions were inside the prefecture were present in group 3. The level of anxiety was associated with the academic course, but not with subjective knowledge of radiation. In contrast, in the qualitative analysis of the free text, 31% considered 'knowledge about radiation' as the reason for the reduction in anxiety level. At the time of the investigation, most young people were not anxious about radiation. However, approximately 20% still had strong anxiety. We established that continuous risk communication is necessary. Furthermore, that stabilization and support related to life in general is important.

Mental Health Problems among Undergraduates in Fukushima, Tokyo, and Kyoto after the March 11 Tohoku Earthquake.

On March 11, 2011, the Great East Japan Earthquake devastated the Tohoku region, which led to a tsunami and a nuclear disaster. While these three disasters caused tremendous physical damage, their psychological impact remains unclear. The present study evaluated traumatic responses, internalizing (i.e., anxiety and depression), and externalizing (i.e., anger) symptoms among Japanese young people in the immediate aftermath and 2.5 years later. A total of 435 undergraduates were recruited from universities in three differentially exposed regions: Fukushima, Tokyo, and Kyoto. They completed a set of questionnaires retrospectively (i.e., September to December 2013) to measure their traumatic responses, anxiety and depressive symptoms, functional impairment, and anger immediately after the disaster and 2.5 years later. Participants in Tokyo had the highest level of traumatic response and internalizing symptoms immediately after the earthquake, whereas those in Fukushima had significantly higher levels of trait anger, anger-in (holding one's anger in), and anger-out (expressing one's anger externally). In Kyoto, the levels of anxiety and depression after 2.5 years were significantly higher than they were immediately after the disasters. In conclusion, anger symptoms were high among young people who lived at or near the center of the disasters, while anxiety and depression were high among those who lived far away from the disasters. These findings suggest the importance of providing mental health services to young people who did not live near the disaster area as well as to those living in the directly affected area.

Development and validation of the Japanese version of the Restorative Sleep Questionnaire in community samples.

OBJECTIVE: This study aimed to validate the Japanese version of the Restorative Sleep Questionnaire Weekly version (RSQ-W-J) and estimate the RSQ-W-J cut-off score to identify the degree of non-restorative sleep (NRS) that interferes with daytime function. METHODS: An online survey was conducted, and 513 participants (241 men, 272 women; mean age, 47.88 ± 16.66 years) completed the questionnaires. The RSQ-W-J, Multidimensional Fatigue Inventory, Athens Insomnia Scale, Patient Health Questionnaire-9, Epworth Sleepiness Scale, Sleep Debt Index, NRS and the degree of daytime dysfunction, and the diagnostic criteria for chronic insomnia were used as implementation scales. RESULTS: The RSQ-W-J was confirmed to have a single-factor structure. Both the Cronbach α coefficient and test-retest reliability of RSQ-W-J were high (α = 0.91; intraclass correlation coefficient [ICC]agreement = 0.85). The RSQ-W-J was significantly negatively correlated with the scales of fatigue, insomnia, depressive symptoms, daytime sleepiness, and sleep debt. In addition, the RSQ-W-J scores of the insomnia group, in which participants met the diagnostic criteria for chronic insomnia, NRS group, in which participants had NRS only, and sleep debt group, in which participants had sleep debt, were significantly lower than those in the normal sleep group. Furthermore, the insomnia group scored significantly lower than the sleep debt group. The RSQ-W-J cut-off score, which indicates whether or not NRS interferes with daytime function, was estimated to be 45.8 points. CONCLUSIONS: The RSQ-W-J was shown to be useful for comprehensively measuring the degree of restorative sleep.

Development and Validation of a Japanese-Language Questionnaire to Screen for Tension-Type Headaches and Migraines.

Introduction Migraine and tension-type headache (TTH) are chronic diseases associated with significant socioeconomic losses and social and psychological impact (current global prevalence: 10% and 38%, respectively). Thus, they require accurate identification and classification. In clinical practice, validated screening tools able to quickly determine migraine and TTH with high sensitivity and specificity help provide an objective and multifaceted understanding of patients' headache symptoms. However, no tool has been developed or validated yet in Japan to ask multifaceted questions about headache-related symptoms in order to identify migraine and TTH and understand these symptoms. This study aimed to develop a questionnaire for screening TTH and migraine. Methods The study was conducted from March to June 2022 at a medical institution in Osaka, Japan. The questionnaire - comprising 24 questions that were generated based on the 3rd edition of the International Classification of Headache Disorders - was used to screen for migraine and TTH, aiming for a deeper understanding of related symptoms. The participants were patients aged ≥18 years with at least one of the following diagnoses: migraine, TTH. The participants were asked to respond in writing or online. The inclusion criteria were age ≥18 years; headache patients attending a hospital; and diagnoses of at least one of the following: migraine, TTH. The informativeness and discriminating ability of the screening items were evaluated using the item response theory. Items with a calculated discrimination ≥1.35 (high or very high) were retained for screening purposes. Basic questions required to screen for primary headaches were retained, despite their limited computational discrimination power. Ultimately, nine and eight screening items were finalized for migraine and TTH, respectively. The previous neurologists' clinical diagnosis of each patient was used as the gold standard reference for calculating sensitivity, specificity, and positive and negative predictive values regarding the screening items. Cohen's kappa coefficients with 95% CIs were also calculated to determine the agreement between the neurologists' clinical diagnosis and the questionnaire results. Results The study population comprised 69 patients aged 19-89 years who were assisted at a hospital division specializing in headache medicine and diagnosed by neurologists. Of these, 22 patients had migraine, 30 had TTH, and 17 had migraine/TTH. Comparing the neurologists' clinical diagnosis with our screening questionnaire results, the sensitivity and specificity were 72.7% and 86.7% for migraine and 50.0% and 86.4% for TTH, respectively. Conclusions Our brief screening tool was highly specific for diagnosing migraine and TTH in individuals with headache symptoms but lacked sufficient sensitivity, especially for TTH. The high specificity for migraine and TTH suggests that the screening tool we developed in this study can correctly identify those who do not have migraine and TTH. The sensitivity was also relatively high for migraine, suggesting that the tool can correctly identify migraine-positive individuals. However, the sensitivity for TTH was low. This tool could help clinicians in providing detailed course assessment of migraine symptoms and TTH symptoms; however, the issue of low sensitivity for TTH needs to be addressed.

Associations Between Recipients' Feelings of Guilt for Donor and Depressive Symptoms Before Living Kidney Transplantation.

BACKGROUND: Recipient depression before kidney transplantation needs to be treated to reduce poor posttransplant outcomes. For recipients who receive living kidney transplantation, feelings of guilt for potential donors may be factors related to the presence of depressive symptoms. This study aimed to examine the association between recipients' feelings of guilt for the donor and depressive symptoms before living kidney transplantation. METHODS: Participants included 178 patients in Sapporo City General Hospital, Hokkaido, Japan, who completed a questionnaire before having living kidney transplantation from April 2009 to May 2016. Feelings of guilt for the donor, depressive symptoms using the Beck Depression Inventory-II (BDI-II), relationship to the donor, dialysis period, and socio-demographic characteristics were assessed via a questionnaire. Multivariate regression analyses were performed to examine the association between feelings of guilt for the donor and BDI-II score after multiple imputations. RESULTS: The results showed that feelings of guilt for donors were associated with depressive symptoms, especially cognitive factors. CONCLUSIONS: These findings indicate that medical staff needs to address recipients' feelings of guilt for donors before living kidney transplantation.

Cognitive profile of patients with burning mouth syndrome in the Japanese population.

The present study investigated which cognitive characteristics, including cancer phobia, self-efficacy, pain-related catastrophizing, and anxiety sensitivity, affect burning mouth syndrome (BMS) symptoms in the Japanese population. A total of 46 BMS patients (44 women and 2 men; mean age, 59.98 +/- 9.57 years; range, 30-79 years) completed a battery of questionnaires, including measures of pain severity, oral-related quality of life (QOL), stress-response, pain-related catastrophizing, self-efficacy, anxiety sensitivity, and tongue cancer phobia. The Pain Catastrophizing Scale (PCS), General Self-Efficacy Scale (GSES), and Anxiety Sensitivity Index (ASI) scores in the BMS patients were compared with the scores of Japanese healthy participants (PCS, n = 449; GSES, n = 278; ASI, n = 9603) reported in previous studies. Catastrophizing and anxiety sensitivity were significantly higher in the BMS patients than in the healthy subjects (P < 0.001). In BMS patients, catastrophizing was significantly correlated with pain severity, stress-response, psychological disability, social disability, and handicap. Cancer phobia was significantly correlated with psychological disability and handicap. Since catastrophizing showed a higher correlation with BMS symptoms than cancer phobia, catastrophizing might be a more significant cognitive factor affecting symptoms than cancer phobia in BMS patients in the Japanese population.

Characteristics and Gender Differences in the Medical Interview Skills of Japanese Medical Students.

Objective To examine the characteristics of the communication skills of medical students, we observed their performance during introductory medical interview training with simulated patients (SPs). Methods The subjects of the present study included fifth-year medical students (male, n=180, female, n=99) who were undergoing clinical training in Japan from 2012 to 2014. Each student was assigned to one of four 10-minute clinical scenarios, which was conducted with an SP. Three or four teachers observed and assessed the performance of each of the students. The overall performance was rated on a 10-point scale, and nine basic communication skills that were common to each of the scenarios were rated using a four-point scale. The students also assessed their own performance on these items. The SPs assessed the students' performance from a patient's perspective on four items. Results There were significant correlations between the teacher and student scores. However, the students tended to score themselves significantly lower than the teachers. The female students were rated significantly higher by the teachers on the following four items; 'eye contact and appropriate attitude,' 'nodding and back-channeling,' 'giving empathic verbal responses,' and 'acquisition of patient's psychosocial information.' However, the self-assessments of the female students were only significantly higher than the male students in one item, 'acquisition of patient's psychosocial information.' In contrast, self-assessments of the male students were significantly higher in two items; none of their items was scored higher by the teachers. There was no significant gender difference in the assessments made by the SPs. Conclusion There were significant gender differences in the communication skills of the medical students during introductory training, suggesting the possibility that there were gender-specific traits and gender-based differences in the students' degrees of readiness.

Short-term effect of back school based on cognitive behavioral therapy involving multidisciplinary collaboration.

ObjectivesThe purpose of this study was to develop a comprehensive back school program that included elements of CBT (Cognitive Behavioral Therapy), implement this through multidisciplinary collaboration, and ascertain its effectiveness as a pilot study. DesignThis school was implemented in the form of five 90-minute group sessions held every other week.MethodsParticipants comprised 7 chronic low back pain patients with poor improvement in the usual treatment. Practitioners were orthopaedic surgeon, physical therapist, and a clinical psychologist. This school contents were patient education, self-monitoring, back exercise, relaxation, stress management, cognitive restructuring, activity pacing, and exposure. ResultsFrom the Wilcoxon signed-rank test, each score of four scales or items (sense of control, PCS (pain catastrophizing), PASS-20 (escape/avoidance), FFD (finger-floor distance)) after this program significantly improved. Results of calculating the effect size, sense of control (d=0.55) is 'moderate', the PCS (d=1.12) and the PASS-20 (d=1.64) were 'large'.ConclusionsThis back school may be useful for physical function and psychological variables which much related to pain management and daily disabilities in patients with poor respond to standard orthopaedic treatment.

Effectiveness of cognitive behavioral therapy based on the pain sustainment/exacerbation model in patients with tension-type headache: a pilot study.

The purpose of this study was to carry out a program of Cognitive Behavioral Therapy (CBT) based on the pain sustainment/exacerbation model for tension-type headache (TTH) patients and to examine the effectiveness as a pilot study. The participants were 4 TTH patients who consulted the outpatient clinic of a university hospital. It consisted of 4 individualized sessions as CBT program (including psychological education, self-monitoring, relaxation technique, cognitive restricting and exposure), and a follow-up examination was carried out 1 month after its completion. The sessions, each of which was 60 minutes long, were executed at weekly intervals. As a result, the score of the Pain Catastrophizing Scale (PCS) decreased after program compared with before program in all patients. The score of escape/avoidance was also reduced at the post-program and follow-up (1 month later) compared with the score of pre-program in patients except Case 2, in whom the score was 0 throughout the study. The degree of the Headache Impact Test (HIT-6) improved by program and changed to "mild" or "none" in all participants. These findings show that in patients with TTH this short CBT program has effect on pain catastrophizing, escape/avoidance and daily disability.
