Maruya S, Tamakoshi K, Hirose M, Takahashi Y, Yamada A, Kato N. Modification of the association between nausea and vomiting of pregnancy and anxiety by personality trait during early pregnancy: A longitudinal study of Japanese pregnant women. Jpn J Nurs Sci 2024; 21:e12565. [PMID: 37789679 DOI: 10.1111/jjns.12565] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/05/2023] [Revised: 08/31/2023] [Accepted: 09/04/2023] [Indexed: 10/05/2023]
Abstract
AIM This study aimed to elucidate whether personality traits modify the relationship between nausea and vomiting of pregnancy (NVP) and anxiety, stratified by three pregnancy periods: 5-8 weeks, 9-12 weeks, and 13-20 weeks. METHODS This longitudinal study was conducted from August 2018 to February 2019 at a perinatal outpatient unit in a general hospital. We included 153 pregnant women aged ≥20 years and under 20 weeks of gestation at their first prenatal visit. They completed the Index of Nausea, Vomiting, and Retching, and the State-Trait Anxiety Inventory (STAI) to measure anxiety in terms of both trait (STAI-T) and state anxiety (STAI-S), and retook them at follow-up checkups for a maximum of three times. RESULTS Using longitudinal data until 20 weeks' gestation, changes in NVP and trait anxiety were significantly associated with changes in state anxiety independently, with trait anxiety being more strongly involved than the change in NVP. This tendency was pronounced in the high-trait anxiety group with STAI-T scores of ≥45. Cross-sectional analyses by gestational week showed similar results in the low-trait anxiety group (STAI-T < 45). In the high-trait anxiety group, only trait anxiety was significantly associated with state anxiety up to 12 weeks gestation. However, only NVP was significantly associated with state anxiety after 13 weeks. CONCLUSIONS Pregnant women who tend to be anxious temperamentally may have other factors that cause anxiety besides nausea immediately after the discovery of pregnancy. Understanding personality traits may help reduce anxiety in pregnant women.

Convolutional neural networks for classifying healthy individuals practicing or not practicing meditation according to the EEG data. Vavilovskii Zhurnal Genet Selektsii 2023; 27:851-858. [PMID: 38213699 PMCID: PMC10777293 DOI: 10.18699/vjgb-23-98] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/11/2023] [Revised: 09/10/2023] [Accepted: 09/13/2023] [Indexed: 01/13/2024] Open
Abstract
The development of objective methods for assessing stress levels is an important task of applied neuroscience. Analysis of EEG recorded as part of a behavioral self-control program can serve as the basis for the development of test methods that allow classifying people by stress level. It is well known that participation in meditation practices leads to the development of skills of voluntary self-control over the individual's mental state due to an increased concentration of attention to themselves. As a consequence of meditation practices, participants can reduce overall anxiety and stress levels. The aim of our study was to develop, train and test a convolutional neural network capable of classifying individuals into groups of practitioners and non-practitioners of meditation by analysis of eventrelated brain potentials recorded during stop-signal paradigm. Four non-deep convolutional network architectures were developed, trained and tested on samples of 100 people (51 meditators and 49 non-meditators). Subsequently, all structures were additionally tested on an independent sample of 25 people. It was found that a structure using a one-dimensional convolutional layer combining the layer and a two-layer fully connected network showed the best performance in simulation tests. However, this model was often subject to overfitting due to the limitation of the display size of the data set. The phenomenon of overfitting was mitigated by changing the structure and scale of the model, initialization network parameters, regularization, random deactivation (dropout) and hyperparameters of cross-validation screening. The resulting model showed 82 % accuracy in classifying people into subgroups. The use of such models can be expected to be effective in assessing stress levels and inclination to anxiety and depression disorders in other groups of subjects.

The impact of negative and positive affectivity on the relationship between work-related psychological factors and work engagement in Japanese workers: a comparison of psychological distress. BMC Psychol 2023; 11:219.

Abstract
BACKGROUND A previous study has shown that Japanese individuals generally exhibit behavior that suppresses the expression of positive emotions, which are strongly affected by affectivity traits. In the present study, to clarify the relationship between affectivity traits and work engagement (WE) or work-related psychosocial factors among Japanese workers, we compared it to the association between psychological distress and these same factors. METHODS A total of 1,000 full-time Japanese regular workers responded to an online survey that measured demographic variables, negative and positive affectivity, job demands and resources, WE, and psychological distress. A hierarchical multiple regression analysis was conducted separately, which used WE and psychological distress as dependent variables. RESULTS The proportion of variance explained by negative and positive affectivity was lower for WE than for psychological distress. However, the proportion of variance defined by job demands and resources was higher for WE than for psychological distress. The proportion of variance explained by all variables for negative and positive affectivity and job demands and resources, and their interactions was approximately equal for WE and psychological distress. CONCLUSION These results emphasize when researchers aim to evaluate the change of psychosocial factors in the workplace, such as improving the workplace environment among Japanese workers, it might be beneficial to measure positive indicators in addition to negative indicators. Furthermore, enriching job resources would be effective in improving WE and alleviating psychological distress.

Abstract
Affective states and traits have been associated with different measures of perceptual stability during binocular rivalry. Diverging approaches to measuring perceptual stability as well as to examination of the role of affective variables have contributed to an inconclusive pattern of findings. Here, we studied the influence of affective traits, such as depressiveness and trait anxiety, and states, which were manipulated with a musical mood induction paradigm, on different measures of perceptual stability (dominance ratios and phase durations) during binocular rivalry. Fifty healthy participants reported alternations in two conditions: a biased perception condition with an unequal probability of perceiving stimuli, using an upright versus a tilted face with a neutral expression, and a control condition with equal chances of perceiving stimuli, using Gabors of different orientations. Baseline positive state affect significantly predicted longer phase durations whereas affective traits did not yield any such effect. Furthermore, in an exploratory analysis, induced negative affect attenuated stimulus related bias in predominance ratios. Overall, we found a strong correlation between both measures of perceptual stability (phase durations and dominance ratios). Our findings thus question the distinction between different measures of perceptual stability during binocular rivalry and highlight the role of affective states in its formation.

Abstract
A growing number of studies have found that the gut microbiota is involved in a variety of psychological processes and neuropsychiatric disorders, which include mood and anxiety disorders. Consumption of dairy products may contain bioactive compounds and probiotic bacteria with various therapeutic benefits. The aim of the study was to investigate possible associations between the frequency of consumption of different types of dairy products and the state of anxiety in university students. The subjects were 311 Azorean university students, 231 women and 80 men, with an average age of 20.5 years. Subjects completed a quantitative questionnaire on the frequency of dairy product consumption and a short version of the Spielberger State-Trait Anxiety Inventory (STAI) test. Among dairy products, semi-skimmed milk was the most commonly consumed, followed by cheese (ripened), drinking yogurt, skim milk, and set yogurt, while fresh cheese, whole milk, and dairy ice cream were the least common. Discriminant analysis showed that consumption of fermented products (yogurt and cheese) was significantly higher (P < 0.05) in the group with low anxiety level (score <40 in STAI test) than in the group with higher anxiety level (score ≥ 40). In this analysis, 62.4% of the initially grouped cases were correctly classified according to the frequency of fermented products consumption. No correlations were found between anxiety and unfermented dairy products. The results indicate that the consumption of fermented dairy products has a positive effect on reducing anxiety in young Azorean university students.

Abstract
This study aimed to assess the efficacy of a text messaging intervention that offered pregnancy and childbirth support. Participants included 39 primigravid women who were less than 12 weeks pregnant. Text messages were sent twice weekly to the intervention group from week 13 of pregnancy until childbirth. Outcome measures were anxiety levels, lifestyle in the month before birth, pre-birth weight, pregnancy complications, delivery complications, birth weight, thoughts regarding the text messages, and the frequency of viewing of the text messages. For the item "I engage in body stretching," the average value in the intervention group was significantly higher than that in the control group. For the item "I have regular bowel movements," the average value in the intervention group was significantly lower. Most participants reported that the intervention was at least somewhat useful. This study indicates that text messaging intervention is practical and can be used to support numerous pregnant women simultaneously at a relatively low cost. Since this is a study pilot trial, large-scale studies are necessary to improve the method and allow for the generalization of the results.

Abstract
BACKGROUND Exploring etiological clues to adolescent depression, especially in female adolescents, might be helpful to improve the social environment of female adolescents. The aim at this study is to explore psycho-social factors of female adolescents with high depressive symptomatology and gender differences in depressive symptoms among Chinese adolescents. METHOD We examined 4100 adolescents from Wuhan city and Jianli county via a cross-sectional study. Depressive symptomatology was screened through the Chinese version of Center for Epidemiology Studies Depression Scale. Multivariate logistic regression was performed to explore the factors related to high depressive symptomatology in female and male adolescents, respectively. RESULTS The prevalence of high depressive symptomatology in female and male were 38.9 and 30.2% respectively. The psycho-social factors of high depressive symptomatology in female adolescents were age (Adjusted odds ratio [aOR] = 1.201, 95% confidence interval [CI], 1.076 ~ 1.341), single parent family (aOR = 2.004, 95%CI, 1.448 ~ 2.772) and fathers' education level (compared to primary school and below, [Junior middle school, aOR = 0.641, 95%CI, 0.439 ~ 0.934; Senior middle school, aOR = 0.603, 95%CI, 0.410 ~ 0.888; College degree and above, aOR = 0.639, 95%CI, 0.437 ~ 0.936]). CONCLUSION Fathers' education level was associated with high depressive symptomatology in female adolescents. Female adolescents whose father with primary school education or below deserves more attention. Further epidemiologic researches need to be conducted to explore the different risk factors between female and male adolescents in China.

Abstract
Purpose The Tampa Scale for Kinesiophobia (TSK) has been used worldwide as a measure of kinesiophobia, but its factor structure in older Japanese adults after lumbar surgery is unknown. The purpose of this study was to fill this research gap by identifying the factors that comprise TSK in older Japanese adults after lumbar surgery. Patients and Methods Participants were older Japanese adults who had undergone surgery for lumbar spinal stenosis. Clinicodemographic data, TSK, intensity of low back pain and leg pain, dysesthesia (using an 11-point numerical rating scale), and HRQOL (using the EQ-5D-5L) were collected. After supplementing the missing values by the multiple assignment method, the hypothetical model of TSK was developed by categorical exploratory factor analysis (weighted least squares method, promax rotation). Confirmatory factor analysis (WLSMV method, promax rotation) was used to compare the hypothetical model and the traditional one-factor and two-factor models. Furthermore, we confirmed the relationship between factors extracted from the hypothetical model and HRQOL, pain, and dysesthesia. Results Questionnaires were mailed to 302 individuals, and responses were obtained from 211 (72.4±4.2 years [range: 65–88]; 115 men and 96 women; 804±343.1 [380–1531] days after surgery; 137 who had undergone decompression and fixation surgery, 74 who had undergone decompression surgery) (response rate: 69.9%). The hypothesized model consisted of “somatic focus,” “activity avoidance,” and “efficacy of physical activities,” all of which were highly consistent. The fit of the hypothetical model was slightly inferior to that of the traditional two-factor model, but the hypothetical model met the criteria for fit. Somatic focus in the hypothetical model was significantly associated with HRQOL, pain, and dysesthesia. Conclusion In older Japanese adults after lumbar surgery, the goodness of fit of the TSK model was maintained by adding efficacy of physical activities as a third factor to the traditional two factors.

Abstract
Determining what factors influence the psychological well-being of undergraduate university students may provide valuable information to inform the development of intervention programs and targeted learning activities. The objective of this study was to investigate the correlation between psychological well-being in university students and their self-reported learning styles and methodologies, social skills, emotional intelligence, anxiety, empathy and self-concept. The final sample consisted of 149 Spanish university students, with an average age of 21.59 years (SD = 4.64). Psychological well-being dimensions, along with learning style and methodology preferences, social skills, level of social responsibility, emotional intelligence, state and trait anxiety, empathy and levels of self-concept were measured using a series of validated self-report scales. The results indicate that the total variance explained by the university students' psychological well-being factors were as follows: i) self-acceptance dimension (R2 = 0.586, F(6,99) = 23.335, p < 0.001); ii) positive relationships dimension (R2 = 0.520, F(6,99) = 17.874, p < 0.001); iii) autonomy dimension (R2 = 0.313, F(4,101) = 11.525, p < 0.001); iv) environmental mastery dimension (R2 = 0.489, F(4,101) = 24.139, p < 0.001); v) personal growth dimension (R2 = 0.354, F(4,101) = 13.838, p < 0.001); and vi) purpose-in-life dimension (R2 = 0.439, F(4,101) = 19.786, p < 0.001). The study findings may be used to inform new educational policies and interventions aimed at improving the psychological well-being of university students in the international context.

Abstract
Using appropriate stimuli to evoke emotions is especially important for researching emotion. Psychologists have provided several standardized affective stimulus databases-such as the International Affective Picture System (IAPS) and the Nencki Affective Picture System (NAPS) as visual stimulus databases, as well as the International Affective Digitized Sounds (IADS) and the Montreal Affective Voices as auditory stimulus databases for emotional experiments. However, considering the limitations of the existing auditory stimulus database studies, research using auditory stimuli is relatively limited compared with the studies using visual stimuli. First, the number of sample sounds is limited, making it difficult to equate across emotional conditions and semantic categories. Second, some artificially created materials (music or human voice) may fail to accurately drive the intended emotional processes. Our principal aim was to expand existing auditory affective sample database to sufficiently cover natural sounds. We asked 207 participants to rate 935 sounds (including the sounds from the IADS-2) using the Self-Assessment Manikin (SAM) and three basic-emotion rating scales. The results showed that emotions in sounds can be distinguished on the affective rating scales, and the stability of the evaluations of sounds revealed that we have successfully provided a larger corpus of natural, emotionally evocative auditory stimuli, covering a wide range of semantic categories. Our expanded, standardized sound sample database may promote a wide range of research in auditory systems and the possible interactions with other sensory modalities, encouraging direct reliable comparisons of outcomes from different researchers in the field of psychology.

Abstract
Abstract. To investigate the effect of response alternatives/scoring procedures on the measurement properties of the Center for Epidemiologic Studies Depression Scale (CES-D) which has the four response alternatives, a polytomous item response theory (IRT) model was applied to the responses of 2,061 workers and university students (1,640 males, 421 females). Test information functions derived from the polytomous IRT analyses on the CES-D data with various scoring procedures indicated that: (1) the CES-D with its standard (0-1-2-3) scoring procedure should be useful for screening to detect subjects with “at high-risk” of depression if the θ point showing the highest information corresponds to the cut-off point, because of its extremely higher information; (2) the CES-D with the 0-1-1-2 scoring procedure could cover wider range of depressive severity, suggesting that this scoring procedure might be useful in cases where more exhaustive discrimination in symptomatology is of interest; and (3) the revised version of CES-D with replacing original positive items into negatively revised items outperformed the original version. These findings have never been demonstrated by the classical test theory analyses, and thus the utility of this kind of psychometric testing should be warranted to further investigation for the standard measures of psychological assessment.

Resilience and depression/anxiety symptoms in multiple sclerosis and neuromyelitis optica spectrum disorder. Mult Scler Relat Disord 2018; 25:309-315. [PMID: 30176401 DOI: 10.1016/j.msard.2018.08.023] [Citation(s) in RCA: 19] [Impact Index Per Article: 3.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/15/2017] [Revised: 07/27/2018] [Accepted: 08/23/2018] [Indexed: 12/30/2022]
Abstract
BACKGROUND Depression and anxiety are common in multiple sclerosis (MS) and recently, studies on these symptoms in neuromyelitis optica spectrum disorder (NMOSD) are increasing. Previous studies suggest that these symptoms have negative effects on the quality of life. Resilience has garnered more interest as one of the protective factors that works to prevent psychiatric symptoms in past decades. There exist a few studies, however, regarding the effects of resilience on these psychiatric symptoms in MS/NMOSD. OBJECTIVE The aim of this study was to clarify the relationships between resilience, psychiatric symptoms, and QOL in patients with MS/NMOSD. METHOD Seventy-seven patients with MS/NMOSD participated in this study. They completed several questionnaires (Beck Depression Inventory-Second edition, Hospital Anxiety and Depression Scale, the Japanese version of the Resilience scale [RS], and Japanese version of Multiple Sclerosis Quality of Life-54). We also collected demographic and clinical data including age, sex, physical disability level (measured with the Expanded Disability Status Scale [EDSS]), and disease duration of the participants. RESULTS The EDSS scores showed significant negative correlations with QOL, unlike disease duration, which did not correlate with either the psychiatric symptoms or QOL. Additionally, there was no significant correlation between RS scores and EDSS scores or disease duration. We also found that resilience showed a significant negative correlation with psychiatric symptoms, and positive correlation with QOL. CONCLUSION These results suggest that resilience may serve to prevent or reduce depression/anxiety symptoms and maintain the QOL regardless of the physical disability level.

Abstract
Objectives: To test the psychometric properties of an adapted Arabic version of the state trait anxiety-form Y (STAI-Y) in Saudi adult dental patients. Methods: In this cross-sectional study, the published Arabic version of the STAI-Y was evaluated by 2 experienced bilingual professionals for its compatibility with Saudi culture and revised prior to testing. Three hundred and eighty-seven patients attending dental clinics for treatment at the Faculty of Dentistry Hospital, King Abdullah University, Jeddah, Kingdom of Saudi Arabia, participated in the study. The Arabic version of the modified dental anxiety scale (MDAS) and visual analogue scale (VAS) ratings of anxiety were used to assess the concurrent criterion validity. Results: The Arabic version of the STAI-Y had high internal consistency reliability (Cronbach’s alpha: 0.989) for state and trait subscales. Factor analysis indicated unidimensionality of the scale. Correlations between STAI-Y scores and both MDAS and VAS scores indicated strong concurrent criterion validity. Discriminant validity was supported by the findings that higher anxiety levels were present among females as opposed to males, younger individuals as compared to older individuals, and patients who do not visit the dentist unless they have a need as opposed to more frequent visitors to the dental office. Conclusion: The Arabic version of the STAI-Y has an adequate internal consistency reliability, generally similar to that reported in the international literature, suggesting it is appropriate for assessing dental anxiety in Arabic speaking populations.

Abstract
PURPOSE Research in the area of cultural response pattern on questionnaires in the oncological setting and direct cross-cultural comparisons are lacking. This study examined response pattern in the reporting of depressive symptoms in Chinese and US women with breast cancer. We hypothesized that Chinese women are less likely to endorse positive affect items compared to their US counterparts. Additionally, we explored cultural differences in the association between positive affect and QOL. METHODS Secondary analyses of baseline assessments of two mind-body intervention studies for women with breast cancer undergoing radiotherapy in the USA (N = 62) and China (N = 97) are presented. All participants completed measures of depressive symptoms (CES-D) and cancer-specific QOL (FACT-B). We examined cultural differences on positive and negative affect items on the CES-D. RESULTS Controlling for demographic factors, ANCOVA revealed a significant cultural difference in positive (F = 7.99, p = 0.005) but not negative affect (p = 0.82) with Chinese women reporting lower positive affect compared to US women (Chinese = 6.97 vs. US = 8.31). There was also a significant cultural difference (F = 3.94, p = 0.03) in the association between positive affect and QOL so that lower positive affect was more strongly associated with worse emotional well-being in Chinese (beta = 0.57, p < 0.0001) than US women (beta = 0.35, p < 0.01). CONCLUSIONS Chinese women reported lower positive affect compared to US women and lower levels of positive affect were more strongly associated with worse QOL. Special attention is needed when examining mental health in different cultures to ascertain effective delivery of clinical services to those in need.

Abstract
It has long been believed that personality traits vary by geographicallocation, but few studies have examined the worldwide distribution of personality profiles. Using the five-factor model of personality—a comprehensive and apparently universal trait structure—we conducted secondary analyses of data from 36 cultures. Distance from the equator and mean temperature were not meaningfully related to personality factors. However, cluster analysis showed that geographically proximatecultures often have similar profiles, and multidimensional scaling showed a clear contrast of European and American cultures with Asian and African cultures. The former were higher in extraversion and openness to experience and lower in agreeableness. A second dimension reflected differences in psychological adjustment. Observed differences between cultures may be the result of differences in gene pools or in features of culture; acculturation studies and the analyses of other natural experiments are needed to understand the origins of geographical differences in personality traits.

Abstract
This article reports a study that documents United States–Japan differences in emotion regulation and demonstrates that those differences are entirely accounted for by individual differences in personality. These findings raise questions about studies that merely document cross-national differences in a psychological variable yet attribute the source of the observed differences to cultural variables without empirical justification to do so. Such differences may be accounted for by aggregate differences in personality.

Abstract
BACKGROUND Oral health disparities exist in the USA. However, little is known of the relationship between oral health disparity and citizenship. The aims of this study were: (i) to describe the differences in self-rated oral health (SROH) between adult American citizens and non-citizens (>20 years of age); and (ii) to test whether factors such as frequency of dentist visits and socio-economic status (SES) are differently associated with SROH in these two groups. METHODS The data used in this study were drawn from the National Health and Nutrition Examination Survey conducted in 2011-2012. Weighted logistic regression models were used to detect the strengths of the association between a series of predictors and SROH. RESULTS More non-citizens (59.54%) than their citizen peers (26.24%) rated their oral health as fair/bad. All factors analysed in this study were differently associated with SROH based on citizenship. More specifically, natural characteristics, such as ethnicity and age, were significantly associated with SROH among non-citizens, and SES was significantly associated with American citizens. Among non-citizens, Hispanic, Non-Hispanic Black and Asian subjects were more likely than Non-Hispanic White subjects to report their oral health as being 'good'. Family poverty level, education and the frequency of dentist visits were significantly associated with SROH among citizens. CONCLUSION The findings of this study indicate that American immigrants report their oral health across most dimensions as being worse than do American citizens. Each explanatory factor may have a different strength of association with SROH in immigrants and citizens, which implies that different steps should be taken within these groups to reduce disparities in oral health.

Abstract
In this article, we describe how cross-cultural research methodologies have evolved, with each phase of research addressing limitations of a previous one. We describe briefly the three previous phases and argue for embarking on a fourth phase that empirically establishes linkages between the active cultural ingredients hypothesized to cause between-country differences and the observed differences themselves. We discuss theoretical considerations and possible empirical methods to establish such linkages, and urge researchers to seriously consider incorporating these kinds of linkage studies in their programs of research.

Abstract
A disturbed beta-endorphin system can be a part of the post-traumatic stress disorder (PTSD) and depression allostasis. Study subjects (N=392) included those with PTSD and/or (stress-induced) depression, and healthy controls with and without traumas. The aim of the study was to examine the network of relations centered around plasma beta-endorphin. The network included anxiety (as a personality trait), traumatic events, pain, aggressiveness, depressive symptoms, and three clusters of PTSD symptoms: intrusions, avoidance, and hyperarousal. Beta-endorphin was represented by individual mean from 13 time points (BEmean), reflecting the total amount of the peripherally secreted hormone, and the coefficient of variation (BEvar), calculated as the ratio of standard deviation to the mean, reflecting the hormone׳s dynamics. BEvar correlated with all other variables, BEmean had no correlations. Structural equation modeling (SEM) was used to examine all interrelations (including their directions) of BEvar and the state/trait variables in the context of their entirety. The model revealed that hyperarousal and anxiety were the only direct agents of peripheral beta-endorphin fluctuations, mediating the effects of other variables. Traumatic events and intrusions act on BEvar via hyperarousal, while depressive symptoms, avoidance, and pain act via anxiety. Hyperarousal should be emphasized as the main agent not only because its effect on BEvar is larger than that of anxiety, but also because it increases anxiety itself (via avoidance and pain). All influences on BEvar are positive and they indicate long-term (sensitizing) effects (as opposed to direct stimulation, for example, by acute pain, anger, etc.). Relations apart from beta-endorphin are also discussed.

Abstract
BACKGROUND The judgment of the approachability of others based on their facial appearance often precedes social interaction. Whether we ultimately approach or avoid others may depend on such judgments. METHOD We used functional magnetic resonance imaging to determine the neural basis for such approachability judgments and the relationship between these judgments and trait anxiety. Participants viewed ambiguous (i.e. neutral) or relatively unambiguous (i.e. angry, happy) faces, assessing either the approachability or the sex of the person depicted. RESULTS Neutral faces elicited more inconsistent responses within participants only during approachability judgment, suggesting ambiguous property as signals. The contrast pertaining to the interaction between task and face valence demonstrated activation in several areas, such that the left amygdala and medial, middle and inferior frontal gyri were responsive to angry faces when subjects were asked to recognize the sex (implicit task) and to neutral faces when required to discern the approachability (explicit task). Moreover, the blood oxygenation level-dependent change within the left amygdala in response to neutral faces during the judgment of approachability was positively correlated with participant trait anxiety. CONCLUSIONS These findings extend a proposed model of social cognition by highlighting the functional engagement of the amygdala in approachability judgments, which underlie an individual's sensitivity to ambiguous sources of probable threat.

Abstract
OBJECTIVES Using subsequent all-cause mortality as a yardstick for retrospective health, this study assessed the comparability of self-rated health (SRH) between non-Hispanic whites and Hispanics. METHODS Based on longitudinal data from 6,870 white and 886 Hispanic respondents aged between 51 and 61 in the 1992 Health and Retirement Study, we related SRH in 1992 to risk of mortality in the 1992-2008 period. Logit models were used to predict white-Hispanic differences in reporting fair or poor SRH. Survival curves and cox proportional hazard models were estimated to assess whether and the extent to which the SRH-mortality association differs between non-Hispanic whites and Hispanics. RESULTS Hispanic respondents reported worse SRH than whites at the baseline, yet they had similar risk of mortality as whites in the 1992-2008 period. Overall, Hispanics rated their health more pessimistically than whites. This was especially the case for Hispanics who rated their health fair or poor at the baseline, whereas their presumed health conditions, as reflected by subsequent risk of mortality, should be considerably better than their white counterparts. DISCUSSION Health disparities between whites and Hispanics aged between 51 and 61 will be overestimated if the assessment has been solely based on differences in SRH between the two groups. Findings from this study call for caution in relying on SRH to quantify and explain health disparities between non-Hispanic whites and Hispanics in the United States.

Abstract
The purpose of the present study was to investigate the effect of chronic stress on the first-night effect in terms of autonomic nervous system activity and anxiety. Participants (N = 11; M age = 20.3 yr., SD = 0.47) included six with high stress (High stress group) and five with low stress (Low stress group), for whom all EEG data were available from three consecutive nights. Heart rate variability was calculated using the MemCalc method. The ratio of low to high frequency of heart rate variability before sleep onset in the High stress group on the first night indicated significantly higher activities than the ratio before sleep onset in the Low stress group. No significant difference in sleep latency was found between the two groups. However, the High stress group was more aware of anxiety than was the Low stress group, and the former estimated more subjective difficulty in falling asleep. These results suggest that measuring LF/HF before sleep may constitute a new way to assess chronic stress.

Abstract
BACKGROUND The OAV questionnaire has been developed to integrate research on altered states of consciousness (ASC). It measures three primary and one secondary dimensions of ASC that are hypothesized to be invariant across ASC induction methods. The OAV rating scale has been in use for more than 20 years and applied internationally in a broad range of research fields, yet its factorial structure has never been tested by structural equation modeling techniques and its psychometric properties have never been examined in large samples of experimentally induced ASC. METHODOLOGY/PRINCIPAL FINDINGS The present study conducted a psychometric evaluation of the OAV in a sample of psilocybin (n = 327), ketamine (n = 162), and MDMA (n = 102) induced ASC that was obtained by pooling data from 43 experimental studies. The factorial structure was examined by confirmatory factor analysis, exploratory structural equation modeling, hierarchical item clustering (ICLUST), and multiple indicators multiple causes (MIMIC) modeling. The originally proposed model did not fit the data well even if zero-constraints on non-target factor loadings and residual correlations were relaxed. Furthermore, ICLUST suggested that the "oceanic boundlessness" and "visionary restructuralization" factors could be combined on a high level of the construct hierarchy. However, because these factors were multidimensional, we extracted and examined 11 new lower order factors. MIMIC modeling indicated that these factors were highly measurement invariant across drugs, settings, questionnaire versions, and sexes. The new factors were also demonstrated to have improved homogeneities, satisfactory reliabilities, discriminant and convergent validities, and to differentiate well among the three drug groups. CONCLUSIONS/SIGNIFICANCE The original scales of the OAV were shown to be multidimensional constructs. Eleven new lower order scales were constructed and demonstrated to have desirable psychometric properties. The new lower order scales are most likely better suited to assess drug induced ASC.

Abstract
Country and ethnic group differences on adjustment have been demonstrated numerous times, and the source of these differences has been typically interpreted as cultural. We report two studies in which country (Study 1) and ethnic group (Study 2) differences on depression, anxiety, optimism versus pessimism, well-being, and self-esteem are mediated by dispositional traits. These findings provide an alternative explanation for previously reported country and ethnic group differences on these variables and encourage researchers to consider multiple sources, including traits, in their models and studies.

Abstract
OBJECTIVES We investigated differences between foreign- and U.S.-born Asian Americans in self-rating their physical and mental health. In particular, we tested whether the foreign-born respondents underreport the extreme categories of the scale as compared with U.S.-born respondents. METHODS We analyzed data from the National Latino and Asian American Study to examine whether immigrants are less likely to use the extreme ends of the 5-category self-rated health scales than their U.S.-born counterparts. We used propensity score matching to derive groups of U.S.- and foreign-born Asian Americans who share similar demographic and health characteristics. We defined propensity scores as predicted probabilities of being U.S. born, given individual background characteristics. The propensity score framework allowed us to make descriptive comparisons of self-rated health responses controlling for background characteristics. We used log-linear symmetry models to examine cross-tabulations of self-rated physical and mental health reports in matched pairs by the 2 (extreme and nonextreme) and 5 ("excellent," "very good," "good," "fair," and "poor") categories. RESULTS Controlling for background characteristics, we found no evidence that foreign-born Asian Americans are less likely to endorse extreme categories in self-rated physical or mental health than U.S.-born Asian Americans, as well as no evidence of imbalances in endorsement of any particular self-rated health category between the 2 groups. CONCLUSIONS Controlling for demographic and health characteristics, we find no systematic differences between foreign- and U.S.-born Asian Americans in reporting self-rated physical and mental health on the 5-category scales from "excellent" to "poor."

Abstract
The Chinese version of Scale for Suicide Ideation (SSI; Beck, Kovacs, & Weissman, 1979) was examined with high school students (n = 292) in rural China. Results indicated that the SSI had high internal reliability and high item-total correlations. The SSI was highly correlated with measures of trait anxiety, hopelessness, and favorable attitude towards suicide. These findings indicated that the Chinese version of the SSI has excellent psychometric properties for measuring suicidal ideation in Chinese populations.

Abstract
A modified CES-D was administered to a community sample of 176 European Americans (EA), 209 Native Hawaiians (NH), and 357 Japanese Americans (JA), yielding measures of depression, positive affect, depressed affect, somatic disturbance, and disturbed interpersonal relations. Positive affect was lower in JA relative to EA, consistent with findings among Native Japanese, a pattern attributed to cultural variation in emotion regulation. NH reported lower positive affect than EA, accompanied by elevated negative affect and somatic disturbance, suggesting generally higher levels of depressive symptoms. The three ethnic groups varied in mental health care usage with differing associations between depressive symptoms and experiences of stressful life events. Taken together, these results suggest ethnic variation in depressive symptoms may arise from differing cultural beliefs.

Abstract
BACKGROUND The State-Trait Anxiety Inventory form Y is a brief self-rating scale for the assessment of state and trait anxiety. The aim of the current preliminary study was to assess the psychometric properties of its Greek translation. MATERIALS AND METHODS 121 healthy volunteers 27.22 +/- 10.61 years old, and 22 depressed patients 29.48 +/- 9.28 years old entered the study. In 20 of them the instrument was re-applied 1-2 days later. Translation and Back Translation was made. The clinical diagnosis was reached with the SCAN v.2.0 and the IPDE. The Symptoms Rating Scale for Depression and Anxiety (SRSDA) and the EPQ were applied for cross-validation purposes. The Statistical Analysis included the Pearson Correlation Coefficient and the calculation of Cronbach's alpha. RESULTS The State score for healthy subjects was 34.30 +/- 10.79 and the Trait score was 36.07 +/- 10.47. The respected scores for the depressed patients were 56.22 +/- 8.86 and 53.83 +/- 10.87. Both State and Trait scores followed the normal distribution in control subjects. Cronbach's alpha was 0.93 for the State and 0.92 for the Trait subscale. The Pearson Correlation Coefficient between State and Trait subscales was 0.79. Both subscales correlated fairly with the anxiety subscale of the SRSDA. Test-retest reliability was excellent, with Pearson coefficient being between 0.75 and 0.98 for individual items and equal to 0.96 for State and 0.98 for Trait. CONCLUSION The current study provided preliminary evidence concerning the reliability and the validity of the Greek translation of the STAI-form Y. Its properties are generally similar to those reported in the international literature, but further research is necessary.

Abstract
This article provides a critical review of the literature on research with self-report measures of depression and anxiety in East Asia. Three trends are noteworthy. First, research on depression and anxiety in East Asia has relied heavily on the use of a limited number of translated instruments. Second, available research suggests that the Asian language versions of these instruments are reliable and valid for use with Asian populations. Third, some subpopulations in East Asia have been studied extensively with respect to depression and anxiety, but there are many regions of Asia where little research literature is available outside of those published in native language journals. The review concludes with recommendations for future research.

Abstract
To examine manifestations of depressive symptomatology among undergraduate students in East Asia, North and South America, responses to the Center for Epidemiologic Studies Depression Scale (CES-D) were compared across Japanese (n = 310), Anglo-American (n = 377), Native American (n = 353), and Argentinean (n = 110) undergraduate students. Japanese reported a significantly higher level of low positive affect, leading to significantly higher total CES-D scores, whereas their negative symptoms score was comparable to scores of Anglo-Americans and Argentineans. Although Native Americans were more likely to endorse negative symptoms, their low positive affect score was comparable to those of Argentineans. Argentineans appear to suffer less from depressive symptoms. Results from a Differential Item Functioning analysis, using Anglo-Americans as the reference group, indicated that: (1) the manifestation of depressive symptoms seemed to be similar for Anglo-Americans and Argentineans, except for low positive affect; (2) Native Americans tended to favor somatic symptoms over affective (depressive) symptoms; (3) responses to positive affect questions could possibly be biased not only for Japanese but also for people in North America; i.e., the expression of positive affect might be enhanced in North American culture, while inhibited in Japanese culture.

Abstract
Little is known about the relationship between olfactory hallucinations and olfactory sensitivity in psychiatric populations. However, in healthy subjects, a 'psychotic-like' feature, namely magical ideation, has been linked to deviant olfactory experiences. We thus assessed olfactory sensitivity, magical ideation and deviant olfactory experiences in 42 healthy subjects (21 Germans and 21 age- and gender-matched Japanese). The results show that: (1) Germans had significantly higher magical ideation scores and a higher frequency of deviant olfactory experiences than Japanese, and more Germans than Japanese reported having had deviant olfactory experiences at least once in their lives; (2) in Germans, the occurrence of deviant olfactory experiences was correlated with higher magical ideation scores; and (3) there was no relationship between olfactory sensitivity (olfactory thresholds) and either deviant olfactory experiences or magical ideation, respectively. We conclude that: (1) the lack of deviant olfactory experiences in Japanese may best be explained by cultural differences in the response attitude towards questionnaires requiring self-disclosure; (2) the positive relationship between magical ideation and deviant olfactory experiences strengthens the supposed link between 'psychotic-like' features in healthy populations and real hallucinations of psychiatric patients; and (3) the absence of a relationship between olfactory sensitivity and deviant olfactory experiences suggests that their anatomical-functional correlates within temporo-limbic regions may differ.

Abstract
To examine variations in the manifestation of depressive symptomatology across racial/ethnic groups, analyses of differential item functioning (DIF) on the Center for Epidemiologic Studies Depression Scale (CES-D) were separately conducted for representative samples of young adults in the following groups: African-Americans (n = 434), Hispanics born in the US (n = 493), and Hispanics born outside the US (n = 395). Non-Hispanic whites (n = 463) were employed as the reference group in all analyses. The effects of gender and age were controlled. DIF analyses indicated that: (1) about half of the CES-D items functioned differently among non-Hispanic whites compared to each of the other racial/ethnic groups; (2) the manifestation of symptoms seemed to be similar for both Hispanic groups, except for low positive affect; (3) African-Americans tended to favor somatic symptoms over affective (depressive) symptoms; (4) Immigrant Hispanics appeared to inhibit the expression of positive affect, and thus more high scorers on the total CES-D were observed within this subgroup. In contrast, no differences were observed when only negative items were considered. The use of positive affect items might artifactually induce spurious differences among people who were born outside the United States or North America.

Abstract
The factor structure and internal consistency of the Japanese adaptation of the State-Trait Anxiety Inventory Form Y (STAI-JY) were examined for 218 Japanese clinical outpatients (86 males, 132 females) with psychiatric and/or psychosomatic complaints. An initial principal-component analysis revealed that the first three components were considered to reflect the "overall anxiety" component, the "presence-absence of anxiety (positive-negative)" component, and the "state-trait anxiety" component. The component related to presence or absence of anxiety was larger than the state-trait anxiety component. Factors followed by an oblique (promax) rotation were labeled "Anxiety-absent" and "Anxiety-present" factors for a two-factor structure, and "Anxiety-present," "Anxiety-absent/state," and "Anxiety-absent/trait" factors for a three-factor structure that was suggested by the scree test. The internal consistencies for both the state and trait anxiety subscales of the STAI-JY were at a satisfactory level, whereas slightly higher Cronbach's as were obtained from separate calculation for anxiety-present and anxiety-absent items. Similarities and differences in the factor structure of the STAI-JY were discussed in comparison with those reported earlier for the general population in Japan and for individuals in Western countries.
