    Suicide is a serious social issue and is often treated using psychological interventions. The current systematic review and meta-analysis aimed to investigate the effectiveness of self-esteem-related interventions on suicidal behaviors. A systematic literature search for randomized controlled trials (RCTs) including a self-esteem component was conducted on 29 May 2021 and updated on 4 April 2022. In total, 12 studies were included in the systematic review and five studies were included in the meta-analysis. Small effect sizes were found for suicidal ideation at post intervention [g = -0.24, 95% CI (-0.48, 0.00)] and a 3-month follow-up [g = -0.36, 95% CI (-0.62, -0.11)]. However, these results should be interpreted cautiously due to the limited number of included studies and varied sample population. In conclusion, the current review suggests that future intervention studies should incorporate self-esteem enhancement in the treatment of suicidal behaviors, especially for suicidal ideation.

    AIMS: We explored the use of pulverized medication as a new method to prevent intentional drug overdose. METHODS: This case study presents data obtained from the medical records of two female patients, aged 19 and 27 years, who presented with schizophrenia and neurodevelopmental disorder, respectively. Both patients provided written informed consent. Medication was administered to the two patients in powdered form, as opposed to in tablet form, in an attempt to prevent intentional drug overdose. RESULTS: This administration method successfully prevented intentional drug overdose for 3 and 5 years in each case, respectively. However, case-control or prospective cohort studies are needed to rule out biases, including cognitive bias. CONCLUSION: Pulverizing medication is a simple and effective means of preventing intentional drug overdose by restricting access to the means of suicide, regardless of the type of mental disorder.

    BACKGROUND: Social anxiety disorder (SAD) develops in the early teens and is a common disorder among university students. Understanding the predictive factors of SAD comorbid with major depressive episode (MDE) is important for student mental health care. The aim of this study was to identify the personality traits that predict SAD with MDE by analyzing longitudinal data of Japanese university students. METHODS: In this retrospective study, Japanese university students who visited the health care center of Hokkaido University for the first time were divided into the following four groups: "Control" (n = 43), "MDE" (n = 16), "SAD" (n = 28), and "SAD with MDE" (n = 61) based on the Patient Health Questionnaire-9 (PHQ-9), the Liebowitz Social Anxiety Scale, and core anxiety symptoms for SAD in the Mini International Neuropsychiatric Interview during screening. Predictors for SAD with MDE were identified by a four-group comparison of the Temperament and Character Inventory and PHQ-9 data previously obtained at the enrollment using analysis of variance and post-hoc tests. RESULTS: Upon comparing the four groups using analysis of variance, there were significant differences in the baseline PHQ-9 summary score, Harm-Avoidance (HA), and Self-Directedness (SD). According to results of the post-hoc test, all three showed a significant difference between the "Control" and "SAD with MDE." Furthermore, there was a significant difference in HA scores between "SAD" and "Control." In all the groups, the mean time from enrollment to the first visit to the center was >2 years. CONCLUSION: A higher HA score at baseline is a predictor of SAD with or without MDE. Higher PHQ-9 summary and lower SD scores at baseline are predictive factors of SAD with MDE.

    AIM: To enable early identification of university students at high risk for suicide, we examined personality as a predictive factor for major depressive episodes and suicide-related ideation. METHODS: From 2011 to 2013, we administered the Patient Health Questionnaire-9 (PHQ-9) and the Temperament and Character Inventory (TCI) to 1,997 university students at enrollment (T1). We previously conducted a study using the same data set; this is a re-analysis of the dataset. To prevent contamination of data, participants diagnosed with a depressive episode were excluded at T1. Three years after enrollment (T2), we re-administered the PHQ-9 to the same students. We statistically compared TCI scores at T1 among depressive episode groups and suicide-related ideation groups. Two-way ANOVA and Cochran-Armitage trend tests were used to analyze the relationships between personality traits, depressive episodes, and suicide-related ideation. RESULTS: The PHQ-9 summary scores at baseline (T1) were 3.0 (±2.7), with female students scoring 4.6 (±2.9) and male students 2.9 (±2.6, p = 0.025). The major depressive episode group at T2 had lower self-directedness (SD) scores at T1 than the non-depressive episode control group. The suicide-related ideation (SI) group at T2 also had higher harm avoidance (HA), lower SD, and lower cooperativeness (C) scores than the non-SI group at T1. The Cochran-Armitage trend tests revealed significant associations between character configurations composed of SD and C, and both depressive episodes at T2 and SI at T2. CONCLUSION: The temperament feature of high HA at baseline and character configurations of low SD and low C at baseline are the most contributory predictors for the novel development of depressive episodes and SI among Japanese university students.

    Abstract Background Previous studies reported that subjective well-being in adulthood correlates with perceived parental bonding in childhood as well as personality traits. However, whether personality traits mediate the effect of perceived parental bonding on well-being or not has not been reported to date. In this study, we hypothesized that ‘parental care and overprotection’ in childhood affect ‘well-being’ in adulthood through various ‘personality traits’, and analyzed this using structural equation modeling. Methods A total of 402 adult volunteers from the community provided responses to the following questionnaires: 1) Parental Bonding Instrument, 2) Temperament and Character Inventory, and 3) The Subjective Well-being Inventory. Two structural equation models were designed and the maximum likelihood estimation method was used for covariance structure analysis. Results Parental care in childhood directly increased well-being in adulthood and indirectly increased it through personality traits (harm avoidance, reward dependence, and self-directedness). Parental overprotection in childhood had no direct effect on well-being in adulthood but decreased well-being in adulthood indirectly through personality traits (harm avoidance, reward dependence, and self-directedness) and increased it through one personality trait (self-transcendence). Conclusions This study showed that the influences of perceived parental bonding on well-being in adulthood are mediated by self-directedness, harm avoidance, reward dependence, and self-transcendence among the seven personality dimensions evaluated by the Temperament and Character Inventory.

    A 40-year-old man presented with generalised dissociative amnesia. At 2 weeks after onset, N-isopropyl-[123I] p-iodoamphetamine-single-photon emission CT imaging of the brain revealed hypoperfusion in the right medial temporal area. Organic brain damage was ruled out. His inability to recall information was attributed to psychological stress related to his employment. Consistent with this diagnosis, his generalised dissociative amnesia lasted 6 years and 10 months; however, he recovered from amnesia naturally on starting a new job. Perfusion of his right medial temporal area also returned to normal levels. Longitudinal reports for generalised dissociative amnesia with natural recovery are exceedingly rare. It is important to confirm whether dissociative amnesia and cerebral blood flow recover in parallel, even in cases where dissociative amnesia is long-lasting.

    自殺企図時には患者が過量服薬をしている例が多く、本邦の救命センターで受け入れる自殺企図患者の半数近くが過量服薬をしていたこと、過量服薬の反復企図例が多いことが繰り返し報告されており、また過量服薬は自殺完遂の強力なリスク因子である。本稿では既報の研究報告の網羅的な文献レビューを行い、主に本邦において過量服薬の予防介入のためにこれまでに試行されてきた対処法を概観し、国内外の研究報告の結果を交え、その有効性と限界について考察した。結果、過量服薬後の入院中の精神医学的治療介入、入院後12ヵ月のフォローアップ型の心理社会的介入、市販薬の法規制については量的なエビデンスが確認された。そのほかにも背景因子を考慮すると、従来推奨されている一般的な精神医学的治療、心理社会的介入、過量服薬の手段へのアクセスの制限、ゲートキーパーの教育研修による予防効果には期待できると考えられた。(著者抄録)

    Background: Patients with schizophrenia or bipolar disorder have a high risk of developing type 2 diabetes. Aims: To identify predictive factors for hyperglycaemic progression in individuals with schizophrenia or bipolar disorder and to determine whether hyperglycaemic progression rates differ among antipsychotics in regular clinical practice. Method: We recruited 1166 patients who initially had normal or prediabetic glucose levels for a nationwide, multisite, l-year prospective cohort study to determine predictive factors for hyperglycaemic progression. We also examined whether hyperglycaemic progression varied among patients receiving monotherapy with the six most frequently used antipsychotics. Results: High baseline serum triglycerides and coexisting hypertension significantly predicted hyperglycaemic progression. The six most frequently used antipsychotics did not significantly differ in their associated hyperglycaemic progression rates over the 1-year observation period. Conclusions: Clinicians should carefully evaluate baseline serum triglycerides and coexisting hypertension and perform strict longitudinal monitoring irrespective of the antipsychotic used.

    BACKGROUND: Suicide has been a leading cause of death among young adult populations in Japan. The aim of this study was to predict major depressive episodes (MDEs) and suicide-related ideation among university students using the Patient Health Questionnaire-9 (PHQ-9) and the Temperament and Character Inventory (TCI). METHODS: The subjects were 2194 university students who completed the PHQ-9 and TCI in the 1st year (T1) and the PHQ-9 in the 4th year (T2) of university. Multiple logistic regression analysis was performed to predict MDEs and suicide-related ideation at T2. Moreover, recursive partitioning analyses were conducted to reveal the future risk of MDEs and suicide-related ideation. RESULTS: The multiple logistic regression analyses of MDEs and suicide-related ideation at T2 revealed that depressive episodes, suicide-related ideation, and low self-directedness(SD) scores at T1 were significant predictors. The area under the curve of the model for MDEs was 0.858 and that for suicide-related ideation was 0.741. The recursive partitioning analyses revealed that a PHQ-9 summary score ≥15 at T1 predicted a high risk of MDEs at T2 and that both a PHQ-9 summary score ≥5 and a PHQ-9 #9 score ≥1 predicted a high risk of suicide-related ideation at T2. CONCLUSIONS: MDEs, suicide-related ideation, and low SD scores are significant predictors of future MDEs and suicide-related ideation.

    In Japan, there are currently no reliable rating scales for the evaluation of subjective cognitive impairment in patients with bipolar disorder. We studied the relationship between the Japanese version of the Cognitive Complaints in Bipolar Disorder Rating Assessment (COBRA) and objective cognitive assessments in patients with bipolar disorder. We further assessed the reliability and validity of the COBRA. Forty-one patients, aged 16-64, in a remission period of bipolar disorder were recruited from Hokkaido University Hospital in Sapporo, Japan. The COBRA (Japanese version) and Frankfurt Complaint Questionnaire (FCQ), the gold standard in subjective cognitive assessment, were administered. A battery of neuropsychological tests was employed to measure objective cognitive impairment. Correlations among the COBRA, FCQ, and neuropsychological tests were determined using Spearman's correlation coefficient. The Japanese version of the COBRA had high internal consistency, good retest reliability, and concurrent validity as indicated by a strong correlation with the FCQ. A significant correlation was also observed between the COBRA and objective cognitive measurements of processing speed. These findings are the first to demonstrate that the Japanese version of the COBRA may be clinically useful as a subjective cognitive impairment rating scale in Japanese patients with bipolar disorder.

    Background Suicide rates are vastly higher in Japan than in many other countries, although the associations between affective temperaments and suicide-related ideations in the general adult population remain unclear. Therefore, we aimed to elucidate these associations in the present study. Methods We analyzed data from 638 Japanese volunteers who completed both the Patient Health Questionnaire (PHQ-9) and the Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Auto-questionnaire (TEMPS-A). Participants were then divided into three groups based on PHQ-9 summary scores and responses to the suicide-related ideation item: non-depressive control group (NC; N = 469), depressive symptoms without suicide-related ideations group (non-SI; N = 135), and depressive symptoms with suicide-related ideations group (SI; N = 34). The depressive symptoms were defined for PHQ-9 summary scores >= 5, and the suicide-related ideations were defined for PHQ-9 #9 score >= 1. We then compared TEMPS-A scores among the groups using Kruskal-Wallis tests. Then the 95% confidence intervals of differences in TEMPS-A subscale scores between the NC and non-SI groups, or between NC and SI groups, were calculated. Results Participants of the SI group exhibited significantly higher scores on the depressive, irritable, and anxious temperament subscales than those of the non-SI group. Similarly, women of the SI group exhibited significantly higher scores of the depressive and irritable temperament subscales than women of the non-SI group, while men of the SI group exhibited significantly higher depressive temperament scores than those of the non-SI group. Among all participants and only men, cyclothymic subscale scores were higher in those of the SI group than the non-SI group (not significant), although the 95% confidence intervals did not overlap. Limitations The cross-sectional study design was the main limitation. Conclusions Depressive, irritable, and anxious temperaments are significant risk factors for suicide-related ideations in the Japanese general adult population. Furthermore, irritable temperament in women and depressive temperament in men are associated with suicide-related ideations.

    BACKGROUND: Previous studies have shown the interaction between heredity and childhood stress or life events on the pathogenesis of a major depressive disorder (MDD). In this study, we tested our hypothesis that childhood abuse, affective temperaments, and adult stressful life events interact and influence the diagnosis of MDD. PATIENTS AND METHODS: A total of 170 healthy controls and 98 MDD patients were studied using the following self-administered questionnaire surveys: the Patient Health Questionnaire-9 (PHQ-9), the Life Experiences Survey, the Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Autoquestionnaire, and the Child Abuse and Trauma Scale (CATS). The data were analyzed with univariate analysis, multivariable analysis, and structural equation modeling. RESULTS: The neglect scores of the CATS indirectly predicted the diagnosis of MDD through cyclothymic and anxious temperament scores of the Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Autoquestionnaire in the structural equation modeling. Two temperaments - cyclothymic and anxious - directly predicted the diagnosis of MDD. The validity of this result was supported by the results of the stepwise multivariate logistic regression analysis as follows: three factors - neglect, cyclothymic, and anxious temperaments - were significant predictors of MDD. Neglect and the total CATS scores were also predictors of remission vs treatment-resistance in MDD patients independently of depressive symptoms. LIMITATIONS: The sample size was small for the comparison between the remission and treatment-resistant groups in MDD patients in multivariable analysis. CONCLUSION: This study suggests that childhood abuse, especially neglect, indirectly predicted the diagnosis of MDD through increased affective temperaments. The important role as a mediator of affective temperaments in the effect of childhood abuse on MDD was suggested.

In this study, we tested our hypothesis that childhood abuse, affective temperaments, and adult stressful life events interact and influence the diagnosis of MDD.Patients and methods: A total of 170 healthy controls and 98 MDD patients were studied using the following self-administered questionnaire surveys: the Patient Health Questionnaire-9 (PHQ-9), the Life Experiences Survey, the Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Autoquestionnaire, and the Child Abuse and Trauma Scale (CATS). The data were analyzed with univariate analysis, multivariable analysis, and structural equation modeling.Results: The neglect scores of the CATS indirectly predicted the diagnosis of MDD through cyclothymic and anxious temperament scores of the Temperament Evaluation of the Memphis, Pisa, Paris, and San Diego Autoquestionnaire in the structural equation modeling. Two temperaments - cyclothymic and anxious - directly predicted the diagnosis of MDD. The validity of this result was supported by the results of the stepwise multivariate logistic regression analysis as follows: three factors - neglect, cyclothymic, and anxious temperaments - were significant predictors of MDD. Neglect and the total CATS scores were also predictors of remission vs treatment-resistance in MDD patients independently of depressive symptoms.Limitations: The sample size was small for the comparison between the remission and treatment-resistant groups in MDD patients in multivariable analysis.Conclusion: This study suggests that childhood abuse, especially neglect, indirectly predicted the diagnosis of MDD through increased affective temperaments. The important role as a mediator of affective temperaments in the effect of childhood abuse on MDD was suggested.

    Objectives: To examine the relationship between level of insight and various subjective experiences for patients with schizophrenia. Materials and methods:Seventy-four patients with schizophrenia who were discharged from our hospital were evaluated. The level of insight into their illness and various subjective experiences were evaluated at discharge. We used the Scale to Assess Unawareness of Mental Disorder (SUMD) for evaluation of insight. In addition, five different rating scales were used to evaluate subjective experiences: Subjective Experience of Deficits in Schizophrenia (SEDS), Subjective Well-being under Neuroleptic drug treatment Short form (SWNS), Schizophrenia Quality of Life Scale (SQLS), Beck Depression Inventory (BDI), and the Drug Attitude Inventory (DAI)-30. Results: The SWNS and the scores for awareness of mental disorder and awareness of the social consequences of mental disorder on SUMD showed a weak positive correlation. The DAI-30 showed a significant negative correlation with most general items on SUMD and a negative correlation between the subscale scores for the awareness and attribution of past symptoms. SEDS, SWNS, SQLS, and the BDI significantly correlated with the subscale scores for awareness of current symptoms on SUMD, and weakly correlated with the subscale scores for attribution of current negative symptoms. Conclusion: Awareness of subjective distress was related to awareness of having a mental disorder. Feeling subjective distress was related to awareness of current symptoms, as well as to the ability to attribute current negative symptoms to a mental disorder. Positive attitudes toward medication correlated with better general insight into the illness. © 2014 Kako et al.

    Over 10 years have passed since the Japanese term for "schizophrenia" was changed from "seishin-bunretsu-byo" to "togo-shiccho-sho" in 2002. An awareness survey targeting doctors suggested that notification of the diagnosis has been encouraged since the Japanese name for schizophrenia was changed. However, no heuristic surveys targeting patients themselves have clarified an increased notification rate, and no multicenter studies of the notification rates have been conducted in recent years. This study targeted schizophrenia patients and their attending physicians to investigate the status of notification of the diagnosis at five medical facilities in Hokkaido, Japan. Questionnaires were distributed to the attending physicians of a total of 869 patients; in addition, the patients themselves filled out questionnaires. Questionnaires were collected from 858 physicians, and valid responses were recovered from 529 patients. This study investigated the status of notification of the diagnosis and compared the attributes of patients who were notified (notified group) with those of patients who were not notified (un-notified group). The results of the survey of attending physicians regarding notification of the diagnosis of schizophrenia indicated that a total of 65.0% patients had been notified, with 63.1% of patients being notified that they had "togo-shiccho-sho" and 2.0% of patients being notified that they had "seishin-bunretsu-byo." Physicians were unsure whether patients had been notified in 18.4% of cases. On excluding these cases, the results indicated that over 79.6% of patients had been notified that they had either "togo-shiccho-sho" or "seishin-bunretsu-byo." The patient questionnaire results regarding patients' awareness of the name of their disease showed that 55.2% answered "togo-shiccho-sho," 3.2% answered "seishin-bunretsu-byo," 9.5% answered the name of another disease, 17.4% answered that they did not know the name of their disease, and 14.7% answered that they knew the name of their disease but did not include any specific details. On excluding these unspecified answers, 68.5% of patients were aware that they had either "togo-shiccho-sho" or "seishin-bunretsu-byo." Comparison of the notified with the un-notified group revealed that the period from treatment initiation in the notified group was shorter than that in the un-notified group, and the mean age of the notified group at the time of the survey was lower than that of the un-notified group. Furthermore, significantly more patients started treatment before 2002, when the Japanese name for schizophrenia was changed, in the un-notified group. The results of this study suggested that the change of the Japanese name of schizophrenia to "togo-shiccho-sho" and historical background resulted in more active notification of the diagnosis.

    Background: The suicide risk among young adults is related to multiple factors; therefore, it is difficult to predict and prevent suicidal behavior. Aim: We conducted the present study to reveal the most important factors relating to suicidal ideation in Japanese university students with major depressive episodes (MDEs) of major depressive disorder (MDD). Methods: The subjects were 30 Japanese university students who had MDEs of MDD, and were aged between 18 and 26 years old. They were divided into two groups - without suicide risk group (n= 15), and with suicide risk group (n= 15) - based on the results of the Mini - International Neuropsychiatric Interview. Additionally, healthy controls were recruited from the same population (n= 15). All subjects completed the self- assessment scales including the Beck Depression Inventory 2nd edition (BDI-II), the Beck Hopelessness Scale (BHS), Rosenberg's Self-Esteem Scale (RSES), and SF-36v2 (TM) (The Medical Outcomes Study 36-item short-form health survey version 2), and they were all administered a battery of neuropsychological tests. Results: The RSES score of the suicide risk group was significantly lower than the RSES score of the without suicide risk group, whereas the BDI-II score and the BHS score were not - significantly different between the two groups. The mean social functioning score on the SF-36v2 of the with suicide risk group was significantly lower than that of the without suicide risk group. Conclusion: The individual's self- esteem and social functioning may play an important role in suicide risk among young adults with MDEs of MDD.

    Quality of life (QOL) has been reported to be impaired in patients with major depressive disorder (MDD), even after remission according to symptom rating scales. Although a relationship between QOL and neurocognitive dysfunction has been reported during depressive episodes, little is known about this relationship in remitted MDD patients. The aim of the present study was to investigate the relationship between QOL and neurocognitive dysfunction in patients with remitted MDD while controlling for confounding factors. Forty-three remitted MDD patients were assessed with neuropsychological tests and QOL, which was measured by a short-form 36-item health survey. The neurocognitive performances of the patients were compared with those of 43 healthy controls. We next evaluated the relationships between neurocognitive impairments, clinical factors, and QOL. Remitted MDD patients had poorer neurocognitive performances than healthy controls for psychomotor speed, attention, and verbal memory. Residual depressive symptoms were strongly associated with QOL. Delayed verbal recall was associated with general health perceptions, which are part of the QOL assessment, even after the effects of the residual depressive symptoms were considered. The results may indicate that clinicians should try to detect neurocognitive dysfunctions that may interfere with QOL using neurocognitive assessments in their daily practice. © 2013 Elsevier Ireland Ltd.

    OBJECTIVE: The aim of our study was to reveal the personality traits of individuals with major and other depressive episodes among the young adult population. Furthermore, character traits of individuals with ideas of suicide or self-harm were also investigated in this study. METHODS: The subjects of this study were 1421 university students who completed the Patient Health Questionnaire (PHQ-9) and the Temperament and Character Inventory (TCI). The subjects were divided into three separate groups: the major depressive episode group (N = 41), the other depressive episode group (N = 97), and the non-depressive controls (N = 1283). This separation was achieved using the PHQ-9 algorithm diagnosis. We compared the TCI scores using an analysis of variance. Moreover, the Cochran-Armitage trend test was used to determine the diagnosis, ideas of suicide or self-harm, and analysis of character profiles. RESULTS: The major depressive episode group had significantly higher HA (P < 0.001), lower RD (P < 0.001), lower SD (P < 0.001), and lower C (P < 0.001) scores than non-depressive controls. The other depressive episode group had significantly higher HA scores (P < 0.001) and lower SD scores (P < 0.001) than non-depressive controls. The Cochran-Armitage trend test revealed that the prevalence of depressive episodes decreased as the character profiles matured (χ(2)(trend) = 57.2, P < 0.0001). The same tendency was observed in individuals who had ideas of suicide or self-harm (χ(2)(trend) = 49.3, P < 0.0001). CONCLUSION: High HA and low SD scores were common personality traits among young adults with major depressive episodes. Furthermore, the immaturity of character profiles was clearly associated with depressive episodes and ideas of suicide or self-harm.

    We report a case in which selegiline, an irreversible monoamine oxidase B (MAO-B) inhibitor, greatly improved depressive symptoms in an adult with stage 5 treatment-resistant major depressive disorder. Four antidepressants and four augmentation therapies had previously been ineffective or intolerable, and electroconvulsive therapy had only a temporary effect. After 20 weeks of treatment with selegiline (10 mg/day), the patient's score on the 17-item Hamilton Depression Rating Scale (HDRS) had decreased from 19 to 4 points. [18F]-Fluorodeoxyglucose positron emission tomography (FDG-PET) showed increased glucose metabolism in the bilateral basal ganglia after initiating selegiline treatment blood dopamine levels were also increased after selegiline treatment. These results raise the possibility that selegiline enhances dopaminergic neural transmission in treatment-resistant depression, thus leading to an improvement in depressive symptoms. © 2013 Kitaichi et al.

    Objective: The aims of this study were to investigate the personality traits of suicide completers using the Temperament and Character Inventory (TCI) scale. Methods: Newly enrolled students who enrolled at Hokkaido University in 1999-2002 and 2004-2007 completed the TCI. Among these students, twenty subjects (2 females and 18 males) later completed suicide. We compared the TCI scales of these subjects with those of 60 (6 females and 54 males) well-matched controls. The controls were matched for age, gender, university department and year of enrollment in the university. Because the number of females was too small, the statistical analyses for the TCI subscales and logistic regression analysis were performed only with the 18 males. Results: A univariate analysis of seven personality dimensions on the TCI revealed higher scores of harm avoidance (HA) in subjects with suicide completion (P=0.034). Analysis of the male subjects showed that suicide completers had higher scores for anticipatory worry (HA1 P=0.007) and fear of uncertainty (HA2, P=0.036) and lower scores for spiritual acceptance (ST3, P=0.038) than did the controls. A multivariate analysis, which was performed to adjust confounding factors, demonstrated significantly higher scores for HA1 among suicide completers (P=0.01, OR=1.32). Conclusions: These results suggest that higher HA scores may predict suicide completion. (C) 2013 Elsevier Inc. All rights reserved.

    To evaluate neurocognitive functions of patients with social anxiety disorder (SAD) without comorbidity using neuropsychological assessments and to investigate the relation between neurocognitive functions and clinical severity of SAD, this study assessed 30 SAD patients (10 female, 20 male) without comorbidity and 30 healthy subjects matched on gender, education level, and age. The neuropsychological assessment consisted of the Wisconsin card sorting test (WCST), the continuous performance test, the trail-making test, the word fluency test, and the auditory verbal learning test. On the WCST, patients showed lower performance than healthy controls did. The Liebowitz Social Anxiety Scale score correlated significantly with the numbers of perseverative errors of the WCST, although the State anxiety score of State-Trait Anxiety Inventory and the Beck Depression Inventory - Second Edition score showed no correlation with neuropsychological test scores. Results show that the executive functioning of patients with SAD was low and that the low functioning correlates with the SAD symptom severity. © 2013 Elsevier Ireland Ltd.

    うつ病に対する行動活性化療法(behavioral activation;BA)の治療効果には数多くの報告がある。今回,我々は反復性うつ病性障害の30代男性にBAを導入した。些細な負荷から症状が再燃し,行動を起こすことに躊躇する傾向がみられたが,粘り強くBAを継続した。その結果,抑うつ症状が改善し,さらには自己効力感の向上も認められた。これらはBAの特徴であるACTIONモデルに基づいた行動から得られた成功体験や達成経験によるものと考えられる。BAの適応の1つに「自己効力感を高めたい時」がある。今後も抑うつ症状が遷延するうつ病に対するBAの適応や有効性についてさらなる知見の蓄積が期待される。(著者抄録)

    2002年に「精神分裂病」から「統合失調症」へと呼称が変更されてから10年以上が経過した.呼称変更後に病名告知が促進されていることは,医師に対する意識調査で示唆されているが,患者自身に対する実態調査では告知率の増加は明らかにされておらず,近年は多施設による告知率の調査も実施されていない.本研究では,北海道内の5つの医療機関において統合失調症患者とその主治医を対象として病名告知状況に関する調査を行った.対象患者全869名に対して主治医に対する調査票と患者に対する質問票により調査を行った.主治医から調査票を回収できたのは858名,患者への質問票を回収でき有効回答として利用できたのは529名であった.病名告知状況を調査するとともに,病名告知群と未告知群の背景を比較した.主治医調査票による病名告知状況の結果は,「統合失調症」と告知している患者が63.1%,「精神分裂病」と告知している患者が2.0%であり,合わせて65.0%であった.告知されているかどうか不明と主治医が回答した患者は18.4%であり,これを除外すると,「統合失調症」もしくは「精神分裂病」と告知している患者は79.6%に上った.患者質問票による病名の認識状況の結果は,「統合失調症」と回答した患者が55.2%,「精神分裂病」3.2%,その他の病名を答えた患者9.5%,病名を知らないと答えた患者17.4%,病名は知っていると回答したものの具体的には記載しなかった患者が14.7%であった.未記載の患者を除外すると,「統合失調症」もしくは「精神分裂病」と認識している患者は68.5%であった.病名告知群と未告知群との比較では,告知群は治療開始からの期間がより短く,調査時年齢もより低かった.治療開始時期が呼称変更された2002年より前の症例は未告知群で有意に多かった.この結果から,「統合失調症」への呼称変更や時代背景の変化により,病名告知がより積極的に行われるようになってきたことが示唆された.(著者抄録)

    三環系抗うつ薬からSSRIへ置換した後、様々な神経認知機能が改善し、職場に適応するなど社会機能回復を認めた大うつ病性障害(MDD)の1例(53歳男性)について報告した。本例のように、抑うつ症状改善後、社会機能障害をきたしてはじめて認知機能障害が疑われるMDD症例は少なくないが、認知機能検査を施行することで、臨床場面では検出困難な軽微な認知機能障害を検出することが可能であると思われた。障害の要因については、疾病そのものの経過や症状レベル、薬剤の影響など様々な側面を考慮する必要があるが、MDDの維持療法を行う際には、認知機能を考慮しながら薬剤変更を試みることには価値があると考えられた。

    修正型電気けいれん療法(m-ECT)後の早期再燃予防の目的でバルプロ酸(VPA)を追加投与した反復性うつ病性障害の1例(49歳男性)について報告した。m-ECT後には早期に再燃する可能性が高く、確実な維持療法を行うことが課題となっている。本症例では職場復帰に伴う病状の不安定さはみられたが、m-ECT後の早期に抑うつ症状の再燃は認められず、VPAの併用療法が再燃予防に有効であった可能性が考えられた。

    医療観察法入院における妄想性障害被害型の症例(40歳代男性)の治療経過について報告した。本症例は持続的な追跡妄想を主症状とし、まったく病識を欠いていたため未治療期間が長く、治療導入が困難であった。しかし、傷害事件を契機として医療観察法入院処遇へと導入され、医療観察法入院の枠組みの中で治療導入し、一定の治療効果が得られた。薬物療法としてはアリピプラゾルを選択し、妄想症状の軽減や病識の獲得などの効果が認められた。以上より、このような妄想性障害に対して医療観察法の入院による治療には一定の効果が期待できることが示唆された。

    自殺者がうつ病に罹患している割合は高く、うつ病治療は自殺予防という観点からも重要であると考えられるが、一方で抗うつ薬による自殺惹起の可能性も報告されている。そこで今回われわれは、当院受診後に自殺既遂に至ったうつ病症例18例について後方視的に調査した。その結果、平均年齢は男性が47.1歳、女性が61.4歳であり男性の方が有意に低かった。さらに初診時における自殺念慮の有無により分類したところ、自殺念慮を表出しなかった症例の方が早期に自殺既遂に至っていた。また、治療的介入について症例対照研究を行い、自殺念慮群において入院症例数が多く、抗うつ薬投与量も有意に多いという結果を得た。本研究では抗うつ薬による自殺惹起の可能性は確認できず、むしろ自殺念慮の表出がないことなどによる病状の過小評価に注意が必要であると考えられた。自殺念慮の表出と自殺既遂との関係についてさらに詳しく調査する必要があると思われた。(著者抄録)

    電気けいれん療法electroconvulsive therapy(ECT)は,大うつ病性障害に対する有効率が80〜90%とも言われている.しかし同時に再燃率も高く,一年後には約半数が再燃するという報告もある.そこで今回われわれは,電気けいれん療法後の維持療法に関して,カルテ調査に基づく後方視的な検討を行った.その結果,電気けいれん療法の反応率は極めて高いものであったが,同時に再燃率は6ヵ月後に51.4%に及んだ.また,ECTの施行理由,使用したECT装置,副作用などについても比較検討した.ECT後の維持療法に関して,非再燃例でsodium valproate(VPA)や高用量のmilnacipranが使用されている例があった.現在までのところ,ECT後の維持療法は確立されておらず,これらの薬剤の再燃予防効果が期待されるため,今後更なる調査が必要であると思われる(著者抄録)
