Comprehensive elucidation of resting-state functional connectivity in anorexia nervosa by a multicenter cross-sectional study.

BACKGROUND: Previous research on the changes in resting-state functional connectivity (rsFC) in anorexia nervosa (AN) has been limited by an insufficient sample size, which reduced the reliability of the results and made it difficult to set the whole brain as regions of interest (ROIs). METHODS: We analyzed functional magnetic resonance imaging data from 114 female AN patients and 135 healthy controls (HC) and obtained self-reported psychological scales, including eating disorder examination questionnaire 6.0. One hundred sixty-four cortical, subcortical, cerebellar, and network parcellation regions were considered as ROIs. We calculated the ROI-to-ROI rsFCs and performed group comparisons. RESULTS: Compared to HC, AN patients showed 12 stronger rsFCs mainly in regions containing dorsolateral prefrontal cortex (DLPFC), and 33 weaker rsFCs primarily in regions containing cerebellum, within temporal lobe, between posterior fusiform cortex and lateral part of visual network, and between anterior cingulate cortex (ACC) and thalamus (p < 0.01, false discovery rate [FDR] correction). Comparisons between AN subtypes showed that there were stronger rsFCs between right lingual gyrus and right supracalcarine cortex and between left temporal occipital fusiform cortex and medial part of visual network in the restricting type compared to the binge/purging type (p < 0.01, FDR correction). CONCLUSION: Stronger rsFCs in regions containing mainly DLPFC, and weaker rsFCs in regions containing primarily cerebellum, within temporal lobe, between posterior fusiform cortex and lateral part of visual network, and between ACC and thalamus, may represent categorical diagnostic markers discriminating AN patients from HC.

Psychometric Properties of the Japanese Translation of the Parent Overprotection Measure for Mother and Father Reports.

The Parent Overprotection Measure (POM) is a promising scale to measure parent overprotection toward a child from the parent's perspective. However, no Japanese translation of the scale has been developed, and whether the POM can be applied to a Japanese population is unknown. This study translated the POM into Japanese and examined its psychometric properties. Parents of 380 children aged 4 to 7 years (including 190 mothers and 190 fathers) completed online questionnaires. Exploratory and confirmatory factor analyses (CFA) indicated that the Japanese translation of the POM has a bi-factor structure, including one general factor (general overprotection) and two specific factors (care/attention and control/prevention). The measurement invariance of reports from mothers' and fathers' perspectives was confirmed by multiple group CFA. The McDonald's Omega was acceptable for all factors, but the general overprotection factor explained most scale variance. Pearson's correlation coefficients were more than .20 between the control/prevention factor and child anxiety symptoms in both mother and father reports. The correlation between the control/prevention factor and parent anxiety according to fathers' reports also exceeded .20. These results provided the factor structure and supported the reliability of the POM among a Japanese population; however, further investigation of the validity of the scale is needed.

Measurement of work-related psychological injury with depressive symptoms.

OBJECTIVE: This study aimed to measure the level of psychological injury caused by work-related stress as well as the severity of depression among workers. METHOD: First, we conducted an online survey and recruited 500 workers diagnosed with depression or adjustment disorder to investigate what type of stress they experienced within six months before onset. Second, we conducted another online survey and recruited 767 participants who experienced some form of work-related stress. All the participants were classified into four groups by whether or not they were diagnosed with depression and whether or not they quit their jobs due to work-related stress. We used the Impact of Event Scale-Revised (IES-R) to measure psychological injury caused by work-related stressful events and the Patient Health Questionnaire (PHQ)-9 to assess the severity of depression. RESULTS: In study 1, 62.4% of workers diagnosed with depression or adjustment disorder experienced work-related stress within six months before onset. In study 2, the IES-R mean scores were 40.7 (SD = 23.1) for Group A (workers with depression and quit their jobs) and 36.67 (SD = 23.4) for Group B (workers with depression but stayed at their jobs), with both exceeding the cut-off point (24/25) of PTSD (Post-Traumatic Stress Disorder), while the mean score of Group C (workers who did not have depression but quit their jobs because of work-related stress) was 20.74 (SD = 21.2), and it was 13.89 (SD = 17.4) for Group D (workers who had work-related stress but stayed at their jobs), with both of them below the cut-off point of PTSD. The total scores of IES-R of Group A and Group B were significantly higher than those of Group C and Group D(p < 0.001). There was a significant positive correlation between the scores of IES-R and PHQ-9 for all four groups (r = 0.708). CONCLUSIONS: This study suggests that it is necessary to measure not only depressive symptoms but also the level of psychological injury resulting from stressful events in the workplace to assess workers with depression.

The effects of a Journey of the Brave Counseling Program on anxiety, well-being, and life adjustment in Taiwanese children.

The purposes of the current study are two-fold. Study 1 aimed to examine the psychometric properties of the Spence Children's Anxiety Scale (SCAS) in a Taiwanese sample. Study 2 aimed to explore the immediate and follow-up effects of Journey of the Brave Counseling Program (JBCP) on children's' anxiety, well-being, and life adjustment. A review and suggestions were provided for future research and practitioners in educational and counseling fields as reference. In Study 1, the pilot study included 150 to 200 children between ages 11 and 12 in Taoyuan City. In Study 2, we conducted a pretest-posttest nonequivalent groups quasi-experimental design. The participants in this stage were 16 children in an elementary school in Taoyuan City, between ages 11 and 12. After obtaining consent forms from the participants' guardians, we randomly assigned these participants to an experimental group (N = 8) and a control group (N = 8). The experimental group received a 40-minute JBCP session weekly for ten weeks. The control group received a 40-minute career exploration small group counseling weekly for ten weeks. We administered the SCAS, Psychological Well-Being Scale, and School Life Adjustment Scale in the pretest, posttest, and follow-up test to measure change of anxiety, well-being, and life adjustment of the participants. In addition, the current study implemented some qualitative data, such as group progress notes, group member feedback questionnaires, and semi-structured interviews with participants' homeroom teachers as supplementary data to clarify the effects of the JBCP. In Study 1, we found that the SCAS had a good validity and reliability for Taiwanese children. The results of Study 2 indicated that the JBCP had immediate and follow-up effects on the separation anxiety in the experimental group. With the pretest impact eliminated, the immediate and follow-up effects on overall anxiety in the experimental group were better than those on the control group. However, even though the immediate and follow-up effects of the JBCP on the experimental group were better than the control group but were not significant. Besides, the group member feedback questionnaires and participants' homeroom teachers all indicated that the experimental group participants had positive attitude toward the JBCP, and they also positively improved their emotions and interpersonal relationships with others.

Cognitive behavior therapy for autistic adolescents, awareness and care for my autistic traits program: a multicenter randomized controlled trial.

BACKGROUND: Autistic people demonstrate focused interests, sensitivity to sensory stimulation, and, compared with the general population, differences in social communication and interaction. We examined whether a combination of the Awareness and Care for My Autistic Traits (ACAT) program and treatment-as-usual is more effective than only treatment-as-usual in increasing the understanding of autistic attributes, reducing treatment stigma, and improving mental health and social adaptation among autistic adolescents and their parents/guardians. METHODS: Forty-nine adolescents and their parents/guardians were randomly assigned to either a combination of ACAT and treatment-as-usual or only treatment-as-usual. The combined group received six weekly 100-minute ACAT sessions, while the treatment-as-usual group received no additional intervention. The primary outcome was the change in understanding of autistic attributes (Autism Knowledge Quiz-Child), administered from pre- to post-intervention. The secondary outcomes included the change in Autism Knowledge Quiz-Parent, reduced treatment stigma, and improved mental health and social adaptation among autistic adolescents and their parents/guardians. A primary outcome measure scale was scored by assessors who were blind to the group assignment. RESULTS: The combined group (both autistic adolescents and their parents/guardians) showed an increase in Autism Knowledge Quiz scores compared to those in the treatment-as-usual group. Autistic adolescents in the combined group also demonstrated a decrease in treatment-related stigma and an improvement in general mental health compared to those in the treatment-as-usual group, while there were no group differences in the change in social adaptation. For parents/guardians, there were no group differences in the change in treatment-related stigma, general mental health, adaptive skills, or attitudes toward their children. CONCLUSIONS: The ACAT program could be an effective treatment modality to increase the understanding of autistic attributes among both autistic adolescents and their parents/guardians. The ACAT program positively affects self-understanding, reduces treatment stigma, and stabilizes behavioral issues for autistic adolescents as a part of mental health measures, but it does not effectively reduce treatment barriers or improve mental health for parents/guardians. Further research should consider whether additional support for parents/guardians could be beneficial. TRIAL REGISTRATION: The study was registered in UMIN (UMIN000029851, 06/01/2018).

Guided parent-delivered cognitive behavioural therapy for Japanese children and parents: a single-arm uncontrolled study.

BACKGROUND: Guided parent-delivered cognitive behavioural therapy (GPD-CBT) is an effective low-intensity treatment for childhood anxiety disorder in Western countries and can increase access to evidence-based psychological therapies. AIM: This study aimed to examine its feasibility in a Japanese sample. METHOD: Twelve children with anxiety disorders and their parents participated in the study, and ten children and parents completed the program. Participants were assessed at pre-, post- and one-month follow-up using a diagnostic interview for anxiety disorders, self- and parent-report measures for anxiety, depression, parental behaviour, and parental anxiety. RESULTS: Four children (40% of completers) were free from their primary diagnoses immediately following the brief treatment, and seven children (70%) at the one-month follow-up. Changes in disorder severity, child and parent reported anxiety symptoms, and child reported depression symptoms were consistent with those found in Western trials of GPD-CBT and of Japanese trials of more intensive CBT for child anxiety disorders that involves both the child and the parent. Moderate increases were also found in child reported parental autonomy behaviours; however, there were only small changes in parent self-reported anxiety. CONCLUSION: These results support the potential of GPD-CBT to increase access to evidence-based treatments for anxiety disorders in Japanese children.

School-based cognitive behavioural intervention programme for addressing anxiety in 10- to 11-year-olds using short classroom activities in Japan: a quasi-experimental study.

BACKGROUND: Although several school-based cognitive behavioural intervention programmes have been developed in Japan to prevent and improve children's anxiety disorders, the substantial time required for their completion remains a problem. METHODS: A brief version of the cognitive behavioural programme called 'Journey of the Brave', developed for Japanese children was conducted among 90 children aged 10‒11 years using 20-min short classroom activities, and its effectiveness was examined. The children were divided into two groups: the intervention (n = 31) and control groups (n = 59). The control group did not attend any programme sessions and followed regular school curriculum. We conducted 14 weekly programme sessions and assessed children at pre-intervention, post-intervention, and 2-month follow-up (6 months after the beginning). The primary and secondary outcome measures were the Spence Children's Anxiety Scale (SCAS) to assess children's anxiety symptoms and the Strengths and Difficulties Questionnaire (SDQ) to measure behaviour problems, respectively. RESULTS: A statistically significant reduction in the SCAS score in the intervention group was found at 2-month follow-up compared with the control group. A significant reduction was also observed in the SDQ score. CONCLUSIONS: Our findings suggested that the 'Journey of the Brave' programme, which requires only 5 h of short classroom activities, demonstrates promising results compared with previous programmes. A larger randomised control trial would be desirable. TRIAL REGISTRATION: UMIN, UMIN000009021, Registered 10 March 2012.

Impact of post-COVID conditions on mental health: a cross-sectional study in Japan and Sweden.

BACKGROUND: Due to the coronavirus disease 2019 (COVID-19) pandemic, people have undermined their mental health. It has been reported that post-COVID conditions at a certain rate. However, information on the mental health of people with post-COVID conditions is limited. Thus, this study investigated the relationship between post-COVID conditions and mental health. METHODS: Design of the present study was an International and collaborative cross-sectional study in Japan and Sweden from March 18 to June 15, 2021. The analyzed data included 763 adults who participated in online surveys in Japan and Sweden and submitted complete data. In addition to demographic data including terms related to COVID-19, psychiatric symptoms such as depression, anxiety, and post-traumatic stress were measured by using the fear of COVID-19 scale (FCV-19S), Patient Health Questionnaire-9 (PHQ-9), General Anxiety Disorder-7 item (GAD-7), and Impact of Event Scale-Revised (IES-R). RESULTS: Of the 135 COVID-19 survivors among the 763 total participants, 37.0% (n = 50/135) had COVID-19-related sequelae. First, the results of the Bonferroni-corrected Mann Whitney U test showed that the group infected SARS-CoV-2 with post-COVID conditions scored significantly higher than those without one and the non-infected group on all clinical symptom scales (P ≤ .05). Next, there was a significant difference that incidence rates of clinical-significant psychiatric symptoms among each group from the results of the Chi-squared test (P ≤ .001). Finally, the results of the multivariate logistic model revealed that the risk of having more severe clinical symptoms were 2.44-3.48 times higher among participants with post-COVID conditions. CONCLUSION: The results showed that approximately half had some physical symptoms after COVID-19 and that post-COVID conditions may lead to the onset of mental disorders. TRIAL REGISTRATION: The ethics committee of Chiba University approved this cross-sectional study (approval number: 4129). However, as no medical intervention was conducted, a clinical trial registration was not necessary.

The mediating effect of symptoms of posttraumatic stress disorder and depression on the relationship between personality traits and quality of life in emergency service workers.

BACKGROUND: Emergency service workers are often exposed to fatalities during accidents or disasters. Therefore, they may be more prone to experiencing posttraumatic stress disorder (PTSD) and depression. It has been shown that these comorbid disorders are related to personality traits and quality of life (QOL). METHODS: We hypothesized that mental disorders, such as symptoms of PTSD and depression, mediate the relationship between personality traits, as measured on the 10-Item Personality Inventory (TIPI), and QOL, as measured on the MOS 36-item Short-Form Health Survey (SF-36). RESULTS: Participants were aged 23-61 years. Questionnaires were sent to 373 participants, 220 of whom returned responses. A direct effect was found between two subscales of the TIPI (Extraversion and Emotional stability) and mental component summary scores of the SF-36 (Extraversion: ß = 0.154, p < .001; Emotional stability: ß = 0.179, p < .001), which indicated partial mediation. A significant indirect effect was revealed between two personality traits and mental health summary scores (Extraversion: ß = 0.058, p < .001; Emotional stability: ß = 0.087, p < .001). We also found a direct effect of extraversion scores of the TIPI on role/social component summary scores of the SF-36 (ß = 0.084, p < .05). However, none of the 95% confidential intervals was significant, which indicated full mediation, and the indirect effect was significant (ß = 0.023, p < .01). Sensitivity analysis indicated that a direct effect between extraversion scores of the TIPI and role/social component summary scores of the SF-36 was significant, which indicated partial mediation. CONCLUSIONS: The findings of direct and indirect effects highlight the importance of identifying effective methods for protecting individuals from developing symptoms of PTSD and depression; moreover, they may help improve QOL. The capacity of dealing with incidents among emergency service workers may vary depending on their personality traits. Therefore, the screening of mental health states that includes a personality trait inventory may be valuable.

Effectiveness of Unguided Internet-Based Cognitive Behavioral Therapy and the Three Good Things Exercise for Insomnia: 3-Arm Randomized Controlled Trial.

BACKGROUND: The treatment of insomnia with sleep medication causes problems such as long-term use, dependence, and significant economic losses, including medical expenses. Evidence-based lifestyle guidance is required to improve insomnia symptoms not only in person but also in easy-to-use web-based formats. OBJECTIVE: This study aims to clarify whether unguided internet-based cognitive behavioral therapy (ICBT) or the Three Good Things (TGT) exercise, both administered as self-help internet interventions without email support, could improve insomnia symptoms compared with a waiting list control (WLC) group. METHODS: A 4-week program was implemented, and participants were randomly allocated to 1 of the 3 groups. The primary outcome measure was the Pittsburgh Sleep Questionnaire (PSQI) score at 4 weeks compared with baseline. RESULTS: Of the 21,394 individuals invited to participate, 312 (1.46%) met the eligibility criteria and were randomly assigned to 1 of the 3 groups. Of these 312 individuals, 270 (86.5%; ICBT 79/270, 29.3%; TGT 88/270, 32.6%; and WLC 103/270, 38.1%) completed a postintervention survey at 4 and 8 weeks. The adjusted mean changes of the primary outcome measure (PSQI) in the ICBT (-1.56, 95% CI -2.52 to -0.59; P<.001) and TGT (-1.15, 95% CI -2.08 to -0.23; P=.002) groups at 4 weeks from baseline showed a significant improvement compared with the WLC group. The adjusted mean changes in the secondary outcome measures of sleep onset latency, total sleep time, Athens Insomnia Scale score, and Patient Health Questionnaire-9 score at 4 weeks from baseline, as well as in the PSQI at 8 weeks from baseline, showed significant improvement for ICBT. Moreover, total sleep time, Athens Insomnia Scale, and Patient Health Questionnaire-9 scores at 4 weeks from baseline showed a significant improvement in the TGT group compared with the WLC group. CONCLUSIONS: A total of 4 weeks of unguided ICBT and TGT exercises improved insomnia.

The Screening Test for Aphasia and Dysarthria (STAD) for Patients with Neurological Communicative Disorders: A Large-Scale, Multicenter Validation Study in Japan.

INTRODUCTION: Evaluation of multiple domains, such as language, articulation, and cognitive function, is frequently required in neurological communicative disorders. The purpose of this study was to investigate the performance of a 10-min screening scale for estimating aphasia, dysarthria, and cognitive dysfunction using a multicenter, large-sized consecutive series. METHODS: We conducted a multicenter validation study that included 314 patients with brain injury between February 1 and June 31, 2018, from 20 medical centers across Japan. The Screening Test for Aphasia and Dysarthria (STAD) was developed in Japan in 2009, and a previous smaller-scale retrospective study established its high to moderate validity. All patients had undergone the STAD, and 212 of them underwent the Western Aphasia Battery or Assessment of Motor Speech for Dysarthria. The effect size on all 29 items and receiver operating curves of 3 sections of the STAD were analyzed based on external criteria, which were decided considering the clinical diagnosis of aphasia, dysarthria, and cognitive dysfunction. Correlations between the STAD and reference tests were calculated. RESULTS: The phi coefficients of 23 out of 29 items exceeded the moderate effect size of 0.3 toward the targeted disorder. Overall, there was a good balance between sensitivity (82-92%) and specificity (77-78%), with moderate to large positive and negative likelihood ratios (3.7-4.19 and 0.1-0.23). The Pearson's r between the verbal section and Western Aphasia Battery Aphasia Quotient, the articulation section and Assessment of Motor Speech for Dysarthria, and the nonverbal section and Western Aphasia Battery Nonlinguistic Skills were 0.89, 0.70, and 0.79, respectively. CONCLUSION: We demonstrated that the STAD has acceptable content and concurrent validity for the assessment of communicative function in patients with brain injury. This short screening tool can be useful in specific contexts, such as in early bedside investigations, to obtain a quick summary of communicative function prior to the administration of other tests, and in cases where more in-depth testing is not feasible.

Attention and Imagery in Cognitive-Behavioral Therapy for Chronic Pain: An Exploratory Study.

Cognitive-behavioral therapy (CBT) has been shown to have a small to medium effect on chronic pain, necessitating further research to identify which components of CBT work for which type of patient. Previously, we developed a high-intensity individual CBT protocol and conducted a single-arm, uncontrolled feasibility study for chronic pain. In the current study, we explored patients' experiences in CBT sessions, including tactile attention-shift training; memory work using the peak-end rule; mental practice of action using motor imagery rescripting; and video feedback, including mirror therapy. Fourteen patients with chronic pain completed 16 CBT sessions. The tactile attention-shift training was very helpful for two patients and somewhat helpful for five, memory work was helpful for nine, mental practice was very helpful for four and somewhat helpful for three, and visual feedback was very helpful for six patients. Effective methodologies for new chronic pain CBT components should be developed. [Journal of Psychosocial Nursing and Mental Health Services, 60(5), 45-54.].

The changes in spinal reciprocal inhibition during motor imagery in lower extremity.

Motor imagery (MI) is known to improve motor function through enhancement of motor cortex activity. Spinal reciprocal inhibition (RI) is modulated by motor cortex activity, and, therefore, MI may change RI. The aim of this study was to examine the changes in RI during MI involving the lower extremity. Spinal RI was measured from the tibialis anterior (TA) to the soleus (SOL). Eleven healthy adults participated in experiment 1. All participants performed the following three conditions, and RI was assessed during each condition: (1) resting condition; (2) MI of ankle dorsiflexion condition (MI-DF); and (3) MI of ankle plantarflexion condition (MI-PF). Twelve healthy adults participated in experiment 2. All participants performed the following two conditions, and RI was assessed before and after MI practice for 10 min: (1) resting condition and (2) MI-DF. The interval between the conditioning and test stimulus (inter-stimulus interval; ISI) was set at 0, 1, 2, or 3 ms and 20 ms. In experiment 1, RI during MI-PF was significantly decreased compared with that during resting with both stimulus intervals. RI during MI-DF showed no significant change compared with that during resting with both ISIs. In experiment 2, the difference between the rest condition and the MI-DF condition after the MI task with ISI of 20 ms was significantly higher than before the MI task. Our findings suggest that real-time changes in RI during MI involving the lower extremity may vary depending on the direction of motion and MI practice.

Specific temperament in patients with nevoid basal cell carcinoma syndrome.

BACKGROUND: Nevoid basal cell carcinoma syndrome (NBCCS) is a neurocutaneous disease, characterized by tumorigenesis and developmental anomalies due to aberrant sonic hedgehog (Shh) signaling. Patients with NBCCS typically appear calm and carefree, suggesting that a specific personality in these patients may be associated with an enhanced hedgehog pathway. Our study aimed to determine the personality type in these patients. METHODS: We enrolled 14 mentally normal patients with genetically confirmed NBCCS (seven males and seven females; mean age = 25.2 years) and 20 controls (10 males and 10 females; mean age = 27.9 years). The patients were assessed with the Japanese version of the Temperament and Character Inventory, based on the seven-dimensional model of temperament and character, and their clinical symptoms were evaluated. The amygdala volumes of six patients with NBCCS were measured using magnetic resonance imaging with image-processing software. RESULTS: Patients with NBCCS scored significantly lower on harm avoidance (0.89) than controls (1.00; P = 0.0084). Moreover, patients with NBCCS and developmental malformations such as rib anomalies, who may have experienced Shh signaling enhancement from the prenatal period, scored significantly lower on harm avoidance (0.80 [P = 0.0031]). The left amygdala volume was also significantly reduced in patients with NBCCS (P = 0.0426). CONCLUSIONS: Patients with NBCCS who experienced increased Shh signaling from the prenatal period showed significantly lower harm avoidance related to serotonin. The left amygdala volume was significantly reduced in these patients. Our results indicate that Shh signaling may influence the human personality.

Effectiveness of Videoconference-Delivered Cognitive Behavioral Therapy for Adults With Psychiatric Disorders: Systematic and Meta-Analytic Review.

BACKGROUND: Cognitive behavioral therapy (CBT) is the gold standard of psychotherapy for psychiatric disorders. However, the format of delivering CBT in person limits access to the intervention. The advancements in information and communication technology, especially the internet, present an opportunity for cognitive behavioral therapists to service patients or clients in remote areas through videoconferencing. Although many randomized controlled trials of videoconference-delivered cognitive behavioral therapy (VCBT) have already been conducted, the overall estimated effect size of VCBT for psychiatric disorders has not been examined by systematic reviews and meta-analyses. OBJECTIVE: This study attempts to evaluate the effectiveness of VCBT for psychiatric disorders through a systematic and meta-analytic review. METHODS: A systematic review and meta-analysis of studies in which VCBT was directly compared to control groups (such as treatment as usual, attention control, wait-list control, and other minimal supports) was carried out. To identify previous studies that meet our study objective, 2 independent reviewers undertook a systematic search through seven databases: MEDLINE (via PubMed), Web of Science, Science Direct, PsycINFO, CINAHL, LILACS, and SciELO. Other databases (ClinicalTrials.gov and Cochrane Central Resister of Controlled Trials) were also checked. All studies included in the review were assessed using the quality criteria of the Cochrane Collaboration. Statistical analysis was performed by using Cochrane Review Manager (RevMan, version 5.4.0). Standardized mean difference was used in major meta-analyses where a P value of .05 or less was the threshold for statistical significance. A heterogeneity test and the chi-square test were performed to assess the presence and extent of statistical heterogeneity with significance set at P<.10. Funnel plots were visually inspected to assess the risk of bias. Subgroup analyses were conducted for each disorder to estimate intervention effects. RESULTS: The systematic search resulted in 16 studies (total N=1745) that met the criteria for this study and were included in the review. There were 10 studies on depressive symptoms, 3 on chronic pain, 1 on generalized anxiety disorder, 1 on obsessive-compulsive disorder, and 1 on hypochondriasis. The quality and risk of bias was also assessed. Results showed a pooled effect size (Hedge g) post treatment of -0.49 (95% CI -0.68 to -0.29), indicating that VCBT is effective for clients with psychiatric disorders. Study quality did not affect outcomes. CONCLUSIONS: While the overall results indicate the effectiveness of VCBT, there are still only a limited number of studies on specific psychiatric and somatic conditions. Therefore, more randomized controlled trials are needed to establish the effectiveness of VCBT for different disorders.

Clinical Effectiveness and Cost-effectiveness of Videoconference-Based Integrated Cognitive Behavioral Therapy for Chronic Pain: Randomized Controlled Trial.

BACKGROUND: Cognitive behavioral therapy is known to improve the management of chronic pain. However, the components of this therapy are still being investigated and debated. OBJECTIVE: This study aimed to examine the effectiveness of an integrated cognitive behavioral therapy program with new components (attention-shift, memory work, video feedback, and image training) delivered via videoconferencing. METHODS: This study was unblinded and participants were recruited and assessed face-to-face in the outpatient department. We conducted a randomized controlled trial for chronic pain to compare 16 weekly videoconference-based cognitive behavioral therapy (vCBT) sessions provided by a therapist with treatment as usual (TAU). Thirty patients (age range, 22-75 years) with chronic pain were randomly assigned to either vCBT (n=15) or TAU (n=15). Patients were evaluated at week 1 (baseline), week 8 (midintervention), and week 16 (postintervention). The primary outcome was the change in pain intensity, which was recorded using the numerical rating scale at 16 weeks from the baseline. Secondary outcomes were pain severity and pain interference, which were assessed using the Brief Pain Inventory. Additionally, we evaluated disability, pain catastrophizing cognition, depression, anxiety, quality of life, and cost utility. RESULTS: In the eligibility assessment, 30 patients were eventually randomized and enrolled; finally, 15 patients in the vCBT and 14 patients in the TAU group were analyzed. Although no significant difference was found between the 2 groups in terms of changes in pain intensity by the numerical rating scale scores at week 16 from baseline (P=.36), there was a significant improvement in the comprehensive evaluation of pain by total score of Brief Pain Inventory (-1.43, 95% CI -2.49 to -0.37, df=24; P=.01). Further, significant improvement was seen in pain interference by using the Brief Pain Inventory (-9.42, 95% CI -14.47 to -4.36, df=25; P=.001) and in disability by using the Pain Disability Assessment Scale (-1.95, 95% CI -3.33 to -0.56, df=24; P=.008) compared with TAU. As for the Medical Economic Evaluation, the incremental cost-effectiveness ratio for 1 year was estimated at 2.9 million yen (about US $25,000) per quality-adjusted life year gained. CONCLUSIONS: The findings of our study suggest that integrated cognitive behavioral therapy delivered by videoconferencing in regular medical care may reduce pain interference but not pain intensity. Further, this treatment method may be cost-effective, although this needs to be further verified using a larger sample size.

Perception of and anxiety about COVID-19 infection and risk behaviors for spreading infection: an international comparison.

BACKGROUND: To control the spread of the new SARS-CoV-2 infection's disease (COVID-19), appropriate precautionary behaviors by the public should be promoted. There are international differences in public cognitive and behavioral pattern, attitudes toward information sources, and anxiety about COVID-19. Information about these differences could increase understanding of the patterns of epidemic-related anxiety and behavior, and would help optimize future policies for preventing the next wave of the epidemic. METHODS: To examine between-country differences in perception, attitude, and precautionary behaviors toward COVID-19, we conducted a cross-sectional study using an online questionnaire survey. Participants were adults who had been registered in Cross Marketing Group Inc. and living in the UK, Spain, or Japan. A total of 8,000 people stratified by age were recruited on a first-come, first-serve basis. Knowledge of and anxiety about COVID-19, the frequency of access and perceived credibility of several information sources, and the frequency of each precautionary behavior were examined on March 27-28, 2020, in Japan and April 17-21, 2020, in the UK and Spain. RESULTS: Knowledge, anxiety, and the frequency of precautionary behaviors were higher in the UK and Spain than in Japan. Participants with infected acquaintances were more concerned about COVID-19. However, participants in the UK rarely wore a medical mask. Participants in the UK and Spain were more eager to obtain information about COVID-19 than those in Japan. Participants in Spain tended not to trust official information and to believe specialists' comments instead. CONCLUSION: The rapidity of the spread of COVID-19, cultural background, and recent political situations seemed to contribute to the international differences here.

Preliminary examination of reliability and validity of the Japanese child anxiety impact scale-parent version in Japanese community sample.

The child anxiety impact scale-parent version (CAIS-P) is a useful measure to assess the impact of anxiety on a child's daily life; however, a Japanese version of the CAIS-P has not been developed, and whether the CAIS-P can be utilized in Eastern countries remains unascertained. The purpose of this study was to develop a Japanese version of the CAIS-P and examine its reliability and validity. Parents of 400 children (aged 7 to 15 years) from the Japanese community completed the CAIS-P. A confirmatory factor analysis indicated that the factor structure of the original CAIS-P, consisting of school activity, social activity, and home/family activity factors, provided a good fit for the Japanese version of the CAIS-P. Estimated Spearman's correlation coefficients showed moderate correlations between the total and factor scores of the CAIS-P, anxiety symptoms (Spence Child Anxiety Scale-parent version), and depressive symptoms (Child Depression Inventory). Furthermore, the item response theory model revealed that each factor of the CAIS-P is a high information reliable measure for children with high trait anxiety. These results provide support for the Japanese version of the CAIS-P's factorial validity, convergent validity, and reliability and its potential for application in child anxiety research in Japan.

Predictors of response to exposure and response prevention-based cognitive behavioral therapy for obsessive-compulsive disorder.

BACKGROUND: Cognitive behavioral therapy (CBT), which includes exposure and response prevention (ERP), is effective in improving symptoms of obsessive-compulsive disorder (OCD). However, whether poor cognitive functions and autism spectrum disorder (ASD) traits affect the therapeutic response of patients with OCD to ERP-based CBT remains unclear. This study aimed to identify factors predictive of the therapeutic response of Japanese patients with OCD to ERP-based CBT. METHODS: Forty-two Japanese outpatients with OCD were assessed using the Wechsler Adult Intelligence Scale-III (WAIS-III), Yale-Brown Obsessive-Compulsive Scale, Patient Health Questionnaire 9-item scale, and Autism Spectrum Quotient (AQ) at pre- and post-treatment. We used multiple regression analyses to estimate the effect on therapeutic response change. The treatment response change was set as a dependent variable in multiple regression analyses. RESULTS: Multiple regression analyses showed that among independent variables, communication as an AQ sub-scale and Letter Number Sequencing as a WAIS-III sub-test predict the therapeutic response to ERP-based CBT . CONCLUSIONS: Our results suggest that diminished working memory (Letter Number Sequencing), poor communication skill (AQ sub-scale) may undermine responsiveness to ERP-based CBT among patients with OCD.

Hemodynamic responses in prefrontal cortex and personality characteristics in patients with bulimic disorders: a near-infrared spectroscopy study.

PURPOSE: This study sought to identify the prefrontal cortex hemodynamic response that is dependent on cognitive performance in patients with bulimic disorders (BD), and investigate its association with personality characteristics. METHODS: Nineteen female patients with BD and 23 healthy women were recruited. Their personality characteristics related to eating disorders were examined using a self-reporting questionnaire, namely the eating disorder inventory-2 (EDI-2). Cerebral blood flow response in the prefrontal cortex during the digit span backward task (DSBT) was measured using near-infrared spectroscopy (NIRS). Change in oxygenated hemoglobin concentration (ΔoxyHb), obtained using NIRS, were used as an index of brain activity. Further, the relationship between prefrontal cortical activity and personality characteristics was investigated in patients with BD. RESULTS: The cognitive performance of patients with BD was significantly lower in the DSBT compared with healthy subjects. There was no difference between the groups in ΔoxyHb during the task. Task scores of patients with BD correlated with asceticism and perfectionism. Moreover, the asceticism score was negatively correlated with ΔoxyHb of the bilateral prefrontal cortex in patients with BD. CONCLUSION: The results suggest that cognitive performance and brain activity induced during DSBT might be affected by asceticism in BD patients. LEVEL OF EVIDENCE: III, case-control study.
