(要約)
AimsThis study aimed to explore the profiles and impact of affective temperaments, together with social and clinical backgrounds, including affective symptoms, in patients with alcohol use disorder (AUD).MethodsThis study included 314 low-risk drinkers and 257 patients with AUD. To assess affective temperament, we used the short version of the temperament evaluation of Memphis, Pisa, Paris, and San Diego. To evaluate depressive and mixed symptoms, the quick inventory of depressive symptomatology self-report Japanese version and 12-item questionnaire for the quantitative assessment of the depressive mixed state were used. We compared the profiles of affective temperaments as well as social and clinical backgrounds, including affective symptoms, between the two groups and further performed logistic regression analyses to explore the factors contributing to AUD.ResultsOur analysis showed higher cyclothymic, hyperthymic, and irritable temperament scores and lower depressive temperament scores in patients with AUD than that in nonclinical drinkers. Regarding other social and clinical backgrounds, patients with AUD were less educated and employed and more experienced depressive and mixed symptoms. Logistic regression analysis identified hyperthymic temperament as a positive contributor and depressive temperament as a negative contributor to AUD.ConclusionsOur findings indicated potential bipolarity in patients with AUD, as manifested by a more hyperthymic temperament in contrast to less depressive temperament. Despite their self-perceived adaptive temperament profiles, patients showed poorer social outcomes and more affective symptoms. This gap may be partly explained by a lack of insight unique to AUD psychology, which potentially disturbs problem recognition.

(要約)
This study aimed to examine potential cognitive impairments in patients with alcohol use disorder (AUD), and explore the factors affecting them. We recruited 97 inpatients with AUD, showing superficially normal cognitive function (mini-mental state examination score ≥24) for this study. We assessed cognitive function after a 4-week post-abstinence period using the Brief Assessment of Cognition in Schizophrenia-Japanese version (BACS-J). Relationships between BACS-J subcategory/composite raw scores and Z-scores (deviation from standard data in healthy Japanese) and background factors such as age, sex, education, smoking status, mini-mental state examination score, body mass index, systolic blood pressure, severity of depression, alcohol consumption, and laboratory findings were analyzed. Multiple regression analysis showed that the age (p < 0.001) and total bilirubin level (p = 0.014) were worsening factors for the BACS-J composite raw score, whereas education (p < 0.001) was a protective factor. An inverse correlation was apparent between the age and the composite Z-score of the BACS-J (r = -0.431, p < 0.001). Receiver operating characteristic (ROC) analysis identified 53 years as the cutoff age for predicting more than -2SD cognitive decline from the normal standard, with a high negative predictive value (95%). Patients with AUD aged ≥53 years showed more pronounced impairments in verbal memory, working memory, verbal fluency, and attention than those younger than 53 years (p < 0.05). These findings clearly demonstrate accelerated age-related cognitive decline in patients with AUD, especially those aged ≥53 years, suggesting the necessity of early intervention in patients with AUD to prevent progressive cognitive impairment and preserve their quality of life.

(要約)
This study was conducted to investigate the relationship between symptoms of gambling problems, gambling behaviours, and cognitive distortions among a university student population in Japan ages 20 to 29ears. We aimed to address the gap in knowledge of gambling disorders and treatment for this population. Data were obtained from 1471 Japanese undergraduate students from 19 universities in Japan. Descriptive statistics and hierarchical multivariate regression analysis were used to investigate whether the factors of gambling cognitive distortions would have predictive effects on gambling disorder symptoms. Results indicated that 5.1% of the participants are classifiable as probable disordered gamblers. The bias of the gambling type to pachinko and pachislot was unique to gamblers in Japan. Of the students sampled, 342 self-reported gambling symptoms via the South Oaks Gambling Screen. Hierarchical multivariate regression analysis indicated that one domain of gambling cognitive distortions was associated significantly with gambling symptoms among the 342 symptomatic participants: gambling expectancy ( = 0.19, p < .05). The multivariate model explained 47% of the variance in the gambling symptoms. This study successfully contributed to the sparse research on university student gambling in Japan. Specifically, our results indicated a statistically significant relationship between gambling cognitive distortions and gambling disorder symptoms. These results can inform the development of preventive education and treatment for university students with gambling disorder in Japan. The report also describes needs for future research of university students with gambling disorder.

(要約)
Conventional categorical criteria have limitations in assessing the prevalence and severity of depressive mixed state (DMX). Thus, we have developed a new scale for screening and quantification of DMX and examined the symptomatological structure and severity of DMX in individuals with major depressive episode (MDE). Subjects were 154 patients with MDE (57 males and 97 females; age 13-83 years). Our original Japanese version of the self-administered 12-item questionnaire to assess DMX (DMX-12), together with the Quick Inventory of Depressive Symptomatology Self-Report Japanese version (QIDS-SR-J) and global assessment of functioning, were administered to each participant. The symptomatological structure of the DMX-12 was examined by exploratory factor analysis. Multiple regression analyses were used to analyze factors contributing to the DMX-12 scale. The relationships of this scale with categorical diagnoses (mixed depression by Benazzi and mixed features by DSM-5) were also investigated. A three-factor model of the DMX-12 was extracted from exploratory factor analysis, namely, "spontaneous instability", "vulnerable responsiveness", and "disruptive emotion/behavior". Multiple regression analyses revealed that age was negatively correlated with total DMX-12 score, while bipolarity and the QIDS-SR-J score were positively correlated. A higher score on the disruptive emotion/behavior subscale was observed in patients with mixed depression and mixed features. The DMX-12 seems to be useful for screening DMX in conjunction with conventional categorical diagnoses. Severely depressed younger subjects with potential bipolarity are more likely to develop DMX. The disruptive emotion/behavior subscale of the DMX-12 may be the most helpful in distinguishing patients with DMX from non-mixed patients.

(要約)
This study aims to examine the effects of multidimensional attitudes towards ambiguity on subclinical depression and anxiety in healthy individuals. Attitudes Towards Ambiguity Scale, consisting of four clusters (enjoyment, anxiety, exclusion, and noninterference), Self-Rating Depression Scale, and State-Trait Anxiety Inventory-trait version were administered to 1019 Japanese volunteers. The result of a regression analysis suggested that the score of Attitudes Towards Ambiguity Scale-enjoyment factor significantly contributed to the Self-Rating Depression Scale score while that of Attitudes Towards Ambiguity Scale-anxiety factor significantly contributed to the State-Trait Anxiety Inventory-trait score. Among attitudes toward ambiguity, enjoyment may have protective effects against subclinical depression whereas anxiety can enhance anxiety-trait in nonclinical individuals.

(要約)
Multi-dimensional structure of the Attitudes Towards Ambiguity Scale (ATAS: original Japanese version) and its relationship with the Acceptance and Action Questionnaire (AAQ) were investigated. We administered the ATAS and the Japanese version of the AAQ to 1019 Japanese healthy volunteers (513 females and 506 males; age range 18-78 years). Trial of exploratory factor analysis extracted four distinct clusters (Enjoyment; α = .83, Anxiety; α = .75, Exclusion; α = .75, and Noninterference; α = .65) from the ATAS item pool, suggestive of diversity in cognitive/ emotional/ behavioral responses to ambiguity. Confirmative factor analysis showed similar goodness in fit indices between the new four-factor model in the present study and the original five-factor model in our previous study (Nishimura 2007). Considering interpretability by using large number of representative samples with general population in the present study, we adopted the four-factor model. The ATAS Anxiety subscale was negatively correlated with the AAQ willingness subscale ( = -.39, < .001), while the ATAS Enjoyment subscale was positively correlated with the AAQ Action subscale ( = .40, < .001). It is thus suggested that one who enjoys ambiguous situations can adopt two distinct attitudes: Excluding ambiguity from active resolution, or not interfering with ambiguity due to good tolerance of this experience, which can lead to positive and flexible commitments in life. In contrast, one who tends to be anxious about ambiguity may be characterized by exclusion-based attitudes due to intolerance of ambiguity, leading to lowered acceptance of their feelings and of the reality of circumstances. Cognitive/emotional attitudes towards ambiguity may affect acceptance of inner experience and active commitment to reality.

(要約)
The present study aimed to investigate differences in personality traits among male-to-female (MtF), female-to-male (FtM) gender identity disorder (GID) subjects and non-transsexual male (M) and female (F) controls. Subjects were 72 MtF and 187 FtM GID subjects without psychiatric comorbidities together with 184 male and 159 female non-transsexual controls. Personality traits were assessed using a short version of the Temperament and Character Inventory (TCI-125). Group comparisons were made by two-way ANOVA. Statistical significances were observed as follows: 1) lower novelty seeking in FtM than in M or MtF, 2) higher reward dependence in FtM than in M, 3) higher cooperativeness in FtM than in M or MtF, 4) the highest self-transcendence in MtF among all the groups. The highest self-transcendence in MtF subjects may reflect their vulnerable identity and constrained adaptation to society as the minority. Nevertheless, higher reward dependence and cooperativeness in FtM subjects can be related to more determined motivation for the treatments of GID and might promise better social functioning and adjustment than MtF subjects.

(要約)
The Ruminative Responses Scale, a measure of depressive rumination, contains two subscales: Brooding and Reflection. Treynor, Gonzalez, and Nolen-Hoeksema (2003) proposed that Brooding is maladaptive and Reflection is adaptive. This article examined the relationships among Brooding, Reflection, and previous depression in two samples of Japanese undergraduates, who were non-depressed at the time of their participation. Based on answers to a self-report measure, participants were divided into a formerly depressed group, who had experienced an episode that met the criteria for major depression, and a never-depressed group. Logistic regression analyses were conducted with Brooding, Reflection, and current depression as the independent variables and past depression as the dependent variable. Brooding had consistent positive associations with past depression. The relationship between Reflection and past depression was not significant for one sample, but was statistically significant and positive in the second sample. In the second sample, Brooding and Reflection both were related with past depression after controlling for worry.

(要約)
The Ruminative Responses Scale (RRS) is a measure of depressive rumination which has two subscales: Brooding and Reflection. This article examines the longitudinal predictions for depression and the test-retest reliability of the Brooding and Reflection of the Japanese RRS. Japanese university students (N = 378) completed the RRS, the Center for Epidemiologic Studies Depression Scale (CES-D), and the Inventory to Diagnose Depression, Lifetime Version (IDDL) which was modified to assess symptoms experienced in the 8-wk. follow-up period. The standardized betas of the initial Brooding and Reflection subscales for the IDDL scores were significant and positive after controlling for baseline CES-D scores, but those for the CES-D scores at Time 2 were not significant. Longitudinal predictions of Brooding were partially consistent with those of other language versions (significant in almost all studies); however, longitudinal predictions of Reflection were not consistent with those of other language versions (negative in previous studies). The test-retest correlations of both subscales were similar to those obtained in Western countries.

The aim of this article was to review the researches on abnormal psychology for depression, and to figure out how to develop the researches in the future. Recently, depression has become a major social problem. Especially, relapse prevention is the most important factor of the depression care. There, we reviewed the researches on abnormal psychology referring the relapse prevention of depression by focusing on the researchers who are active on this field. The main topics of the present article were below: the emotional processing theory by John D. Teasdale, the first person who has focused on the relapse prevention of depression, 2) the researches that substantiate the theory, and the distinguishing phenomenon related to the relapse, 3) the researches on the effect and mechanism of MBCT that is developed for the relapse prevention of depression, and 4) the research trend of Ed Watkins and Jutta Joormann who lead the recent growth of the abnormal psychology on the depression, and the relations between their theory and the MBCT. At the last, the future directions of the researches on the relapse prevention on depression were discussed. Furthermore, it was noted that the perspective which was necessary to understand the mindfulness was beneficial when think of emotion regulation too.
