Article: The factor structure of the Chinese version of the Temperament and Character Inventory: Factorial robustness and association with age and gender.
[show abstract] [hide abstract]
ABSTRACT: OBJECTIVE: To examine the factor structure of the 144-item Chinese version of the Temperament and Character Inventory (TCI) and its association with age and gender in a large non-clinical population. METHOD: We recruited 1966 non-clinical participants in China who completed the TCI Chinese version. They were randomly divided into two independent samples. One sample (n=983) was used for exploratory factor analysis (EFA), and the other (n=983) for confirmatory factor analysis (CFA). RESULTS: An EFA suggested a four-factor structure for temperament domains and a three-factor structure for character domains. This was confirmed by a CFA. Women showed significantly higher scores on harm avoidance, reward dependence, co-operativeness, and self-transcendence than men. Age affected every subscale expect for reward dependence. CONCLUSION: The factor structure of the Chinese TCI was similar to the original factor structure, with some differences reflecting the culture of a Chinese population.Comprehensive psychiatry 12/2012; · 2.08 Impact Factor -

Article: Intergenerational Transmission of Parenting Style and Personality: Direct Influence or Mediation?
[show abstract] [hide abstract]
ABSTRACT: In order to examine the relationships between parenting styles and personality traits over generations, a cross-sectional questionnaire study was conducted for fathers and mothers of school-age children of grades 5–9. The parenting styles measured by the Parental Bonding Instrument (PBI) and the personality traits measured by the Temperament and Character Inventory (TCI) were correlated within and between the consecutive generations (the grandparents and the parents for the PBI and the parents and the children for the TCI). A series of structural equation modeling showed that (1) while the parenting styles were transmitted directly from the grandparents to the parents, it was partly mediated by the fathers’ Co-operativeness (C) but not so for the mothers, (2) while the personality traits were transmitted directly from the parents to the children, it was only the fathers’ parenting styles that mediated C, and (3) the parents’ parenting styles had independent effects upon the children’s personality traits.Journal of Child and Family Studies 04/2012; 18(5):541-556. · 1.12 Impact Factor -
Article: The Effect of Interpersonal Touch During Childhood on Adult Attachment and Depression: A Neglected Area of Family and Developmental Psychology?
[show abstract] [hide abstract]
ABSTRACT: Interpersonal touch has been little studied empirically as an indicator of parent- and peer-child intimacy. Undergraduate students (n=390) were studied using a questionnaire survey regarding the frequencies of interpersonal touch by father, mother, same-sex peers, and opposite-sex peers during preschool ages, grades 1–3, grades 4–6, and grades 7–9, as well as their current attachment style to a romantic partner and current depression. A path model indicated that current depression was influenced significantly by poorer self- and other-images as well as by fewer parental interpersonal touches throughout childhood. Other-image was influenced by early (up to grade 3) parental interpersonal touch. Our findings suggest that a lower frequency of parental touching during childhood influences the development of depression and contributes to a poorer image of an individual’s romantic partner during later adolescence and early adulthood.Journal of Child and Family Studies 04/2012; 19(1):109-117. · 1.12 Impact Factor -
Article: Influence of the municipal merger on local government employees' stress response in Japan.
[show abstract] [hide abstract]
ABSTRACT: In Japan, mergers of cities, towns, and villages have occurred rapidly as a result of the Special Law on the Merger of Municipalities, enacted in 2005. These mergers may impact civil servants' psychological adjustment. We developed the Municipal Merger Stress Questionnaire (MMSQ) to measure the impact of the municipal mergers and collected responses from 570 employees who had experienced a municipal merger (Study 1). We examined the relationships among the impact of municipal merger, Stress Responses, Self-concept (self-esteem and interpersonal dependency), and Social Support (Study 2). Two factors (Increased Workload and Worthlessness) were derived from the MMSQ in Study 1. Additionally, a structural equation model showed that the impact of the loss of value of their job (Worthlessness) related to the psychological stress responses, while job discretion did not differentiate an entire stress situation in Study 2. The result implies that psychological aspects of interventions focused on worthlessness are required to maintain good mental health of public servants at workplaces.Industrial Health 02/2012; 50(2):132-41. · 0.94 Impact Factor -
Article: Narcissism: Its function in modulating self-conscious emotions.
[show abstract] [hide abstract]
ABSTRACT: This study focused on the functional aspects of narcissism in regulating self-conscious emotions (guilt, shame, hubristic pride, and achievement-oriented pride) as well as two other attribution styles (externalization and detachment). The authors investigated Japanese university students (N = 452) with regard to their self-conscious emotions using the Test of Self-Conscious Affect-3 (TOSCA-3) and their narcissistic personality using the short version of Narcissistic Personality Inventory (NPI-S). Structural equation modeling was used for the analysis. The authors found that narcissism led individuals to feel achievement-oriented pride, hubristic pride, externalization, and detachment, but inhibited feelings of shame. It did not have a significant effect on guilt. Shame-proneness prompted hubristic pride and externalization. Guilt-proneness inclined an individual toward achievement-oriented pride, but deterred externalization. In this article, the authors present and interpret these results in detail and then discuss how they can be utilized in psychotherapy.Bulletin of the Menninger Clinic 01/2012; 76(3):211-34. · 0.72 Impact Factor -
Article: Effects of temperament and character profiles on state and trait depression and anxiety: a prospective study of a Japanese youth population.
[show abstract] [hide abstract]
ABSTRACT: Objective. To examine the effects of temperament and character profiles on state and trait depression and anxiety in a Japanese youth population. Method. Japanese university students were solicited for participation in a two-wave study, with assessments performed at Time 1 (T1) and Time 2 (T2), separated by a five-month interval. A total of 184 students completed the Japanese version of the temperament and character inventory (TCI) at T1 and the Hospital Anxiety and Depression Scale (HADS) at T1 and T2. We posited two latent variables, trait depression and anxiety, composed of the T1 and T2 HADS depression and anxiety scores, respectively. We also posited that temperament domain traits would predict character domain traits, and that all the personality traits would be linked to trait depression and anxiety and also predict T2 depression and anxiety. Results. Structural regression modeling showed that (1) only high Novelty Seeking predicted T2 Anxiety score, (2) trait depression and anxiety were linked to high harm avoidance and low self-directedness, and (3) trait depression was linked to high self-transcendence whereas trait anxiety was linked to low reward dependence, persistence, and cooperativeness. Conclusion. The characteristic associations between TCI subscales and depression and anxiety were limited to the trait rather than state aspects of depression and anxiety.Depression research and treatment 01/2012; 2012:604684. -
Article: Psychometric properties of the Japanese version of the Clinical Outcomes in Routine Evaluation-Outcome Measure.
[show abstract] [hide abstract]
ABSTRACT: This study examined the reliability and validity of the Japanese version of the Clinical Outcomes in Routine Evaluation-Outcome Measure (CORE-OM), a standardized, brief, but comprehensive outcome measurement. The target population consisted of 1684 Japanese company employees, hospital staff, and university students. A confirmatory factor analysis proved that our data fit the factor structure of the original CORE-OM. We also examined its internal consistency, test-retest reliability, convergent validity, and sensitivity in discriminating between clinical and nonclinical samples. After demonstrating these results, we discuss how the Japanese version of the CORE-OM can be used both in clinical and research settings.Comprehensive psychiatry 11/2011; 53(5):600-8. · 2.08 Impact Factor -
Article: Effects of self-esteem on state and trait components of interpersonal dependency and depression in the workplace.
[show abstract] [hide abstract]
ABSTRACT: This longitudinal study was undertaken to clarify the relationships among self-esteem, interpersonal dependency, and depression, focusing on a trait and state component of interpersonal dependency and depression. In a sample of 466 working people, self-esteem, interpersonal dependency, job stressor, and depression were assessed at 2 points of time. A structural equation model (SEM) was created to differentiate the trait component of interpersonal dependency, depression and the state component of interpersonal dependency, depression. The model revealed that self-esteem influenced trait interpersonal dependency and trait depression but not state interpersonal dependency or depression. Setting a latent variable as a trait component to differentiate trait and state in interpersonal dependency and depression in SEM was found to be effective both statistically and clinically.Journal of Clinical Psychology 06/2011; 67(9):918-26. · 2.12 Impact Factor -
Article: Self-conscious affects: their adaptive Functions and relationship to depressive mood.
[show abstract] [hide abstract]
ABSTRACT: This study used a structural equation model to examine the influence of resilience on the four self-conscious affects (guilt-proneness, shame-proneness, externalization, and detachment) assessed in the Test of Self-Conscious Affect-3 (TOSCA-3) and their impact on depressive mood. Our subject population consisted of 447 Japanese university students. The first analysis explored which TOSCA-3 affects help an individual adapt to stressful situations. The concept of "resilience" was used as an indicator to evaluate the adaptive functions. We based this on the assumption that an individual with higher resilience is able to use more adaptive affects. In the second analysis, taking the above relationship between resilience and the self-conscious affects into consideration, we examined how those variables as well as a negative life event are related to depressive mood. To assess the resilience level and depressive mood, we adopted the Resilience Scale (RS) and Self-rating Depressive Scale (SDS), respectively. The first analysis showed that the more resilient an individual was, the more prone they were to "detachment" and the less "shame" they experienced. The level of resilience did not have a significant effect on "guilt" or "externalization." In the second analysis we found that "resilience" had a direct inverse effect on depressive mood that was also mediated by "shame" and "detachment." We discuss how the particular self-conscious affects comprising each adaptive function are related to depressive mood.American journal of psychotherapy 01/2011; 65(1):27-46. -
Article: The effects of temperament and character on symptoms of depression in a chinese nonclinical population.
[show abstract] [hide abstract]
ABSTRACT: Objective. To examine the relations between personality traits and syndromes of depression in a nonclinical Chinese population. Method. We recruited 469 nonclinical participants in China. They completed the Chinese version temperament and character inventory (TCI) and self-rating depression scale (SDS). A structural equation model was used to rate the relation between seven TCI scales and the three SDS subscale scores (based on Shafer's meta-analysis of the SDS items factor analyses). This was based on the assumption that the three depression subscales would be predicted by the temperament and character subscales, whereas the character subscales would be predicted by the temperament subscales. Results. The positive symptoms scores were predicted by low self-directedness (SD), cooperativeness (C), reward dependence (RD), and persistence (P) as well as older age. The negative symptoms scores were predicted only by an older age. The somatic symptoms scores were predicted by high SD. Conclusion. Syndromes of depression are differentially associated with temperament and character patterns. It was mainly the positive symptoms scores that were predicted by the TCI scores. The effects of harm avoidance (HA) on the positive symptoms scores could be mediated by low SD and C.Depression research and treatment 01/2011; 2011:198591. -

Article: The Relationship of Temperament and Character Dimensions to Perceived Parenting Styles in Childhood: A Study of a Japanese University Student Population
[show abstract] [hide abstract]
ABSTRACT: To examine the association between perceived parenting styles in childhood and temperament and character dimensions in adolescence and early adulthood, 836 college students in Japan were assessed using the Temperament and Character Inventory (TCI) and the Parental Bonding Questionnaire (PBI). A path analysis revealed that Novelty Seeking and Harm Avoidance were associated with low Self-Directedness and low Cooperativeness; Novelty Seeking, Reward Dependence, and Persistence were associated with Self-Transcendence; and Reward Dependence was associated with Cooperativeness. It also showed that Perceived Parenting (parents' high Care and low Overprotection) was associated with low Harm Avoidance and high Persistence, and was directly associated with Self-Directedness, Cooperativeness, and low Self-Transcendence. These findings suggest that perceived parenting styles are more associated with character dimensions than temperament dimensions. This link was direct or indirect via temperament dimensions.01/2011; 411:9-14. -
Article: Effects of child abuse history on borderline personality traits, negative life events, and depression: a study among a university student population in Japan.
[show abstract] [hide abstract]
ABSTRACT: To simultaneously examine the impact of childhood abuse history on borderline personality traits, negative life events, and depression, undergraduate students (N=243) were studied by questionnaire surveys with one week intervals. Neglect and emotional abuse as well as sexual maltreatment predicted borderline personality traits and baseline depression. Baseline depression as well as the impact of negative life events occurring the week prior predicted depression a week later. However, after considering the baseline depression level, child abuse history failed to predict the follow-up depression level. Borderline personality traits did not moderate these findings. Childhood emotional and sexual abuse history may influence depression and borderline personality traits.Psychiatry Research 12/2010; 180(2-3):120-5. · 2.52 Impact Factor -
Article: Understanding externalizing behavior from children's personality and parenting characteristics.
[show abstract] [hide abstract]
ABSTRACT: A total of 946 Japanese children in the 5th to 9th grades and their parents were studied in order to investigate the extent to which parenting characteristics (measured by the Parental Bonding Instrument) and the personality of the child (measured by the junior version of the Temperament and Character Inventory) would be associated with the two aspects of the externalizing problems--aggression and delinquency--of the child (measured by the Child Behavior Checklist). A series of regression analyses demonstrated that (1) aggressive children were higher in Novelty Seeking, and delinquent children were higher in Novelty Seeking and lower in Harm Avoidance, and (2) both aggressive and delinquent children were characterised by low maternal care, paternal over-protection, and low maternal overprotection. A structural equation model confirmed these findings except for the link between the two externalizing behaviour scores and the maternal care. Moreover, it was suggested that Novelty seeking of the child would be predicted by low parental care and low paternal and high maternal overprotection. The children's aggression and delinquency could, to some extent, be explainable by their temperament patterns and parental characteristics.Psychiatry Research 12/2009; 175(1-2):142-7. · 2.52 Impact Factor -
Article: The Test of Self-Conscious Affect-3 in Japanese university students.
[show abstract] [hide abstract]
ABSTRACT: The psychometric properties of the Japanese Test of Self-Conscious Affect-3 (TOSCA-3), a self-report measure of self-conscious emotions, were examined in Japanese university students. Confirmatory factor analyses showed good fits of the theory-driven model for 6 emotions to the data. The subscales of the TOSCA-3 showed moderate correlations and internal consistency. Only the Shame subscale was greater among younger students, but women had higher shame and guilt than men. Social desirability moderately influenced some subscales. Test-retest reliability was good for shame and guilt. Time 1 shame predicted time 2 depression a week later. The Japanese version of the TOSCA-3 is a reliable and valid measure of self-conscious emotions among a Japanese population.The Journal of nervous and mental disease 07/2009; 197(6):458-60. · 1.77 Impact Factor
