Temperament and character in patients with borderline personality disorder taking gender and comorbidity into account

This study examined correlations of borderline personality disorder (BPD) symptoms with scales from Cloninger's psychobiological model taking gender and psychiatric comorbidity into consideration. Inpatients with BPD (n = 202) were compared to several control groups including psychiatrically healthy persons (n = 327), subjects with affective disorders (n = 46), alcohol use disorders (n = 47), cluster C personality disorders (n = 23) and antisocial personality disorder (n = 25). The results indicate that only males with BPD presented an 'explosive' temperament suggested by Cloninger, with simultaneously high levels of novelty seeking and harm avoidance. In contrast, women with BPD were characterized by high levels of harm avoidance, but not novelty seeking. Regarding temperament and character dimensions our analyses suggest that patients with BPD could be characterized, in particular, by a combination of high harm avoidance and very low self-directedness. The specific temperament configuration of BPD postulated by Cloninger's psychobiological model could only partially be supported. The results provide support for the importance of controlling for gender effects when investigating the applicability of dimensional models with respect to personality disorders.     

Temperament, character, and quality of life in patients with schizophrenia and their first-degree relatives

The aim of this study was to investigate the associations between the temperament, character dimensions, and quality of life (QOL) of patients with schizophrenia; their first-degree, nonaffected relatives; and healthy control subjects. One hundred twenty patients, the same number of first-degree relatives, and the same number of control subjects were assessed using the Temperament and Character Inventory and the Quality of Life Enjoyment and Satisfaction Questionnaire. Patients were also assessed using the Positive and Negative Syndrome Scale. Patients and relatives had a significantly lower QOL than control subjects, controlled for temperament and character dimensions. Patients scored significantly higher than control subjects in harm avoidance and self-transcendence and lower in novelty seeking and self-directedness. First-degree relatives had lower results for novelty seeking and scored higher on self-transcendence than control subjects. Harm avoidance, self-directedness, and self-transcendence were the dimensions of Temperament and Character Inventory shown to be the most significant predictors of QOL. Psychopathology and age were also significant predictors of QOL. Our understanding of an individual patient's QOL must include personality evaluation.     

Temperament and character in persons with borderline personality disorder

High comorbidity, suicidal ideation, difficult temperament, and character are key symptoms of persons with borderline personality disorder (BPD). We investigated 478 persons, 40 of whom had a BPD according SCID-II, self-rating. Participants were examined with a semistructured interview and several self-rating questionnaires in their households. Taking the high comorbidity of persons with BPD into account, we compared the BPD group with four control groups with different axis 1 or personality disorders and one nonclinical group. Persons with BPD showed high comorbidity with affective, anxiety, and alcohol use disorders. With respect to suicidality, 75% reported that they wish to be dead at least sometimes, and about one-third said that they had already attempted suicide. Regarding temperament and character dimensions, our analyses revealed higher novelty seeking for persons with BPD compared to participants without BPD, although this difference was primarily attributable to males with BPD. Additionally, participants with BPD reported higher harm avoidance compared to control groups, while this was more distinctive for females. Finally, we found that persons with BPD had very low levels of self-directedness. This effect was independent from gender and was found in all group comparisons. Therapy of BPD should take into account high comorbidity and suicidality of patients. Moreover, our results show that low self-directedness seems to be specific for persons with BPD. Therefore, therapy must address those deficits by focusing on skills training as well as on aspects of maturation.     

Bulimic family dynamics: role of parents' personality--a controlled study with the Temperament and Character Inventory

The numbers of studies on the familial environment and personality of bulimic women have increased in recent years and results have revealed interesting features. In this study, we evaluated the temperament and character traits of patients with bulimia nervosa (BN) and their mothers and fathers, and we analyzed the correlation of temperament and character traits among members of these bulimic families. Finally, we tested the ability of the Temperament and Character Inventory (TCI) to discriminate between normal controls and bulimic subjects, their parents, and their families. Using the TCI, temperament and character features of 28 bulimic patients and their parents (23 fathers and 28 mothers) were analyzed and then compared with a control group of 29 women and their 27 fathers and 29 mothers. Data suggest that both temperament and character factors are involved in BN. Bulimic individuals were high in harm avoidance and low in self-directedness. Their mothers were distinguished by low self-directedness. The fathers were low in persistence. Harm avoidance of bulimic women positively correlated with harm avoidance and negatively with self-directedness of their mothers. The bulimic family had low self-directedness as a common denominator observed in all family members. The observation that both temperament and character have important roles in the etiopathogenesis of bulimia nervosa has important treatment ramifications. The TCI was useful in discriminating between normal controls and bulimic subjects, their parents, and the whole family.     

Borderline personality disorder in major depression: symptomatology,temperament, character,differential drug response,and 6-month outcome

Among 183 depressed patients participating in a randomized long-term treatment trial of fluoxetine and nortriptyline, 30 patients had borderline personality disorder (BPD), 53 had other personality disorders (OPD), and 100 had no personality disorders (NPD). The borderline depressed patients had earlier age of onset of their depressions, more chronic depressions, more alcohol and cannabis comorbidity, and were more likely to have histories of suicide attempts and of self-mutilation. On self-report, patients with BPD and OPD reported more phobic symptoms, greater interpersonal sensitivity, and more paranoid ideation. Uniquely, BPD patients were more angry than OPD patients. BPD patients had high novelty seeking, high harm avoidance, low self-directedness, and low cooperativeness. Depressed patients with BPD did poorly in the short term if treated with nortriptyline rather than fluoxetine. After 6 months, those with BPD had a favorable outcome in regard to depressive symptoms, social adjustment, and even improvement in the character measure of self-directedness. Those with the poorest outcome were those with OPD.     

Anorectic family dynamics: temperament and character data

Modern psychobiologic research conceptualizes personality as a complex adaptive system involving a bidirectional interaction between heritable neurobiologic dispositions (temperament) and social learning (character). In this study, we evaluated temperament and character traits of patients with anorexia nervosa and their mothers and fathers, and we analyzed the correlation of temperament and character traits among family members in anorectic families. Finally, we tested the ability of the Temperament and Character Inventory (TCI) to discriminate between normal controls and anorectic subjects, their parents, and their families. Temperament and character features of 50 restricter anorectic patients and their parents (23 fathers and 25 mothers) were analyzed and then compared with a control group of 60 women and their 20 fathers and 20 mothers using the TCI. Data suggest that both temperament and character factors are involved in anorexia nervosa (AN). Anorectic individuals were high in harm avoidance (HA), low in novelty seeking (NS), and high in persistence (P) ("obsessive temperament type"). Their character was remarkable for low self-directedness (SD). Their mothers were distinguished by low SD. The fathers were high in HA, but also low in P, and high in reward dependence (RD). Again, they were low in SD. The anorectic family had low SD as a common denominator observed in all family members. This finding indicates that the psychopathology of AN extends beyond obsessiveness, but combines obsessiveness with low character development. None of the above temperament and character profiles is pathognomic of restricter anorectics. The observation that both temperament and character have an important role in the etiopathogenesis of AN has important treatment ramifications. The TCI was useful in discriminating between normal controls and anorectic subjects, their parents, and the whole anorectic family.     

Temperament and character as schizophrenia-related endophenotypes in non-psychotic siblings

BACKGROUND: Quantitative endophenotypes are needed to better understand the pathogenesis of schizophrenia. The psychobiological model of temperament and character suggests that personality traits are heritable and regulated by brain systems influencing schizophrenia susceptibility. Thus, measures of temperament and character may serve as schizophrenia-related endophenotypes in individuals with schizophrenia and their non-psychotic siblings. METHODS: Individuals with schizophrenia (n=35), their non-psychotic siblings (n=34), controls (n=63), and their siblings (n=56) participated in a study of the clinical, neurocognitive and neuromorphological characteristics of schizophrenia. A mixed-model approach assessed group differences on the Temperament and Character Inventory (TCI). Neurocognitive deficits and psychopathology were correlated with the TCI. Configurations of TCI domains were examined using a generalized linear model. RESULTS: Individuals with schizophrenia and their non-psychotic siblings had higher harm avoidance than controls and their siblings. Individuals with schizophrenia had lower self-directedness and cooperativeness, and higher self-transcendence than their non-psychotic siblings, controls, and the siblings of controls. Neurocognition was not related to temperament and character in individuals with schizophrenia or either control group. In non-psychotic siblings, self-directedness and cooperativeness were correlated with working memory and crystallized IQ. CONCLUSION: Evidence supports harm avoidance as a schizophrenia-related endophenotype. An increased risk of schizophrenia may be associated with asociality (configured as high harm avoidance and low reward dependence), schizotypy (configured as low self-directedness, low cooperativeness, and high self-transcendence), and neurocognitive deficits (poor executive functioning, working/episodic memory, attention, and low IQ). The non-psychotic siblings demonstrated features of a mature character profile including strong crystallized IQ, which may confer protection against psychopathology.     

Genetic and environmental bases of the interplay between magical ideation and personality

Sub-threshold psychotic symptoms are quite commonly present in general population. Among these, Magical Ideation (MI) has been proved to be a valid predictor of psychosis. However, the genetic and environmental influences on the interplay between MI and personality have not fully been explored. A total of 534 adult twins from the population-based Italian Twin Register were assessed for MI using the MI Scale (MIS) and for personality with the temperament and character inventory (TCI). A Multivariate Cholesky model was applied with Mx statistical program. The best-fitting model showed that additive genetic and unshared environmental factors explain approximately the same proportion of variance in MI, whereas a less strong genetic influence on personality traits emerged. Relevant correlations between MI and specific personality traits (novelty seeking, cooperativeness, self-directedness, self-transcendence) were found, suggesting shared influences for MI and these traits. Both genetic and environmental factors explained these correlations, with genetic factors playing a predominant role. Moderate-to-substantial genetic effects on MI and personality were found. Shared genetic and environmental effects underlie the phenotypic correlation between MI (psychosis-proneness) and personality traits, i.e. self-directedness (negative association) and self-transcendence (positive association), potentially representing predictive markers of psychosis liability related to schizotypy and personality.     

Adolescent attachment styles and their relation to the temperament and character traits of personality in a general population.

Attachment styles as well as personality traits in adolescents and adults have been found to be associated with their health outcomes and with their personality pathology. In this cross-sectional exploratory study, we study the relationship between attachment styles that derive from our data employing the items of Feeney et al. (1994) self-report attachment style questionnaire (ASQ), and personality traits given by the junior version of Cloninger et al. (1993) self-report temperament and character inventory (TCI), in a sample of 426 adolescents (54% females) from a general population. The secure attachment style was correlated significantly negatively with the personality trait harm avoidance (HA), but significantly positively with the personality traits novelty seeking (NS), reward dependence (RD), cooperativeness (CO) and self-transcendence (ST). The preoccupied (anxious/ambivalent) attachment style was correlated significantly positively with HA and NS, but significantly negatively with self-directedness (SD). The fearful-avoidant category was correlated significantly negatively with NS. Our five-factor solution of the attachment styles and their relation to the TCI point towards a need for a modification of the two-axis, four-category attachment model of Bartholomew (1990) and Bartholomew and Horowitz (1991), with their category dismissing-avoidant replaced by the two categories defined here as dismissing relations (correlated significantly negatively with CO) and dismissing others (correlated significantly negatively with RD and significantly positively with SD).     

Personality in schizophrenia assessed with the Temperament and Character Inventory (TCI)

The Temperament and Character Inventory (TCI) is a well-established self-report questionnaire measuring four temperament and three character dimensions. However, surprisingly few studies have used it to examine the personality of patients with schizophrenia, and none in Japan. Moreover, possible gender differences in personality among patients with schizophrenia have not been well documented. We administered the TCI to 86 Japanese patients with schizophrenia and 115 age- and gender-matched healthy controls to characterize personality traits in patients with schizophrenia and to examine their relationships with clinical variables, particularly gender and symptoms. Compared with controls, patients demonstrated significantly lower novelty seeking, reward dependence, self-directedness and cooperativeness, and higher harm avoidance and self-transcendence. Male patients showed even more pronounced personality alteration than female patients when both of them were compared with healthy people. Personality dimensions were moderately correlated with symptom dimensions assessed by the Positive and Negative Syndrome Scale (PANSS). These results, together with prior findings in several other countries, suggest that schizophrenia patients have a unique personality profile which appears to be present across cultures and that the greater alteration of personality in schizophrenia males might be related to their poorer social and community functioning.     

Personality traits and schizophrenia: evidence from a case-control study and meta-analysis

Personality is considered to be an important aspect of schizophrenia, primarily because it may influence patients' symptoms and social functioning. Specific personality traits are related to schizophrenia. The Temperament and Character Inventory (TCI) measures four traits of temperament - novelty seeking (NS), harm avoidance (HA), reward dependence (RD) and persistence (PS) - and three traits of character - self-directedness (SD), cooperativeness (CO) and self-transcendence (ST). We investigated associations between schizophrenia and personality traits using the TCI in a Japanese case-control sample (99 patients and 179 controls). Patients with schizophrenia scored higher on HA and ST and lower on NS, RD, SD and CO compared with controls in our case-control sample. We then performed a meta-analysis of samples from the published literature and our sample (384 patients and 656 controls). We found no evidence of heterogeneity among studies, except for NS in the overall population. Possible associations between personality traits (HA, RD, PS, SD, CO and ST) and schizophrenia were revealed. The effect sizes (Hedges' g) of the temperament traits were 0.98 for HA, -0.43 for RD and -0.23 for PS, and those of the character traits were -0.96 for SD, -0.47 for CO and 0.61 for ST. These findings suggest that patients with schizophrenia have a unique temperament and character profile compared with the general population.     

Interrelations between temperament, character, and parental rearing among delinquent adolescents: a cross-validation

We performed a cross-validation of results from investigations in juvenile delinquents in Russia and Germany concerning relationships of personality characteristics in terms of temperament and character with parental rearing. Both studies used the Temperament and Character Inventory (TCI) based on Cloninger's psychobiological theory, and the Own Memories on Parenting (Egna Minnen Betr?ffande Uppfostran-Swedish [EMBU]) questionnaire on parental rearing based on Perris' vulnerability model. The inter-relatedness of parental rearing, temperament, and character traits in socially normally integrated adolescents, as well as in delinquent adolescents, implying direct and indirect pathways from personality and parental rearing to delinquency, could be cross-validated. Differences between delinquents and socially normally integrated adolescents are rather based on different levels of expressions of various temperament traits, harm avoidance and novelty seeking in particular, and the character trait self-directedness, as well as on parental rearing behavior (predominantly parental rejection and emotional warmth) than on different structures within related developmental processes.     

Temperament and character traits in patients with bipolar disorder and associations with comorbid alcoholism or anxiety disorders

Temperament and character traits may determine differences in clinical presentations and outcome of bipolar disorder. We compared personality traits in bipolar patients and healthy individuals using the Temperament and Character Inventory (TCI) and sought to verify whether comorbidity with alcoholism or anxiety disorders is associated with specific personality traits. Seventy-three DSM-IV bipolar patients were compared to 63 healthy individuals using the TCI. In a second step, the bipolar sample was subgrouped according to the presence of psychiatric comorbidity (alcoholism, n=10; anxiety disorders; n=23; alcoholism plus anxiety disorders, n=21; no comorbidity, n=19). Bipolar patients scored statistically higher than the healthy individuals on novelty seeking, harm avoidance and self-transcendence and lower on self-directedness and cooperativeness. Bipolar patients with only comorbid alcoholism scored statistically lower than bipolar patients without any comorbidity on persistence. Bipolar patients with only comorbid anxiety disorders scored statistically higher on harm avoidance and lower on self-directedness than bipolar patients without any comorbidity. Limitations of this study include the cross-sectional design and the small sample size, specifically in the analysis of the subgroups. However, our results suggest that bipolar patients exhibit a different personality structure than healthy individuals and that presence of psychiatric comorbidity in bipolar disorder is associated with specific personality traits. These findings suggest that personality, at least to some extent, mediates the comorbidity phenomena in bipolar disorder.     

Temperament and character factors in Korean children with seizure disorders

Although the organic and psychosocial consequences of seizure disorders are thought to affect temperament and character patterns, these patterns in children with seizure disorders have not yet been investigated. We therefore investigated temperament and character patterns in Korean children with seizure disorders and their associations with seizure-related variables. The Korean version of the Junior Temperament and Character Inventory was used to assess temperament and character factors of 65 children with seizure disorders (32 boys, 33 girls; mean age, 10.6 +/- 1.8 years) and 65 healthy controls matched for age and sex. Children with seizure disorders showed higher harm avoidance, and lower persistence, self-directedness, and cooperativeness than controls. In children with seizure disorders, character factors such as self-directedness, cooperativeness, and self-transcendence were significantly associated with seizure type, and cooperativeness was correlated with seizure severity. Novelty seeking and self-directedness were correlated with paternal educational level and parental economic status, respectively. These findings suggest that children with seizure disorders have distinctive temperament and character patterns, with seizure type being the most influential factor modulating character patterns.     

Influence of temperament and character on resilience

Objective

The purpose of this study was to examine the influence of temperament and character on resilience.

Methods

A total of 4355 participants completed two questionnaires: the Conner–Davison Resilience Scale (CD-RISC) and the Temperament and Character Inventory-Revised Short (TCI-RS). We used Pearson's correlations to evaluate the correlation between the dimensions of the TCI and the CD-RISC. To determine the most influential TCI dimension with respect to the CD-RISC, a backward multiple regression analysis was performed.

Results

The resilience of both men and women was positively correlated with persistence, self-directedness, and cooperativeness. Conversely, harm avoidance was negatively correlated with resilience. In addition, reward dependence in men and self-transcendence in women were positively correlated with resilience. In the multiple regression analysis, persistence, self-directedness, and harm avoidance significantly predicted resilience after adjusting for age and gender.

Conclusion

This results show that social support is affected by personality, which consists of both temperament and character. High persistence and self-directedness as well as low harm avoidance are found to contribute to a better stress response.     

The influence of personality traits and emotional and behavioral problems on repetitive nonsuicidal self-injury in a school sample

BackgroundNonsuicidal self-injury (NSSI) is highly prevalent among adolescents and associated with various mental health problems and suicidality. Previous studies have found that certain personality traits are related to NSSI behavior, however only few studies examined personality traits in adolescents with NSSI. Our study aimed to assess the relationship between personality traits and emotional and behavioral problems in predicting repetitive NSSI among adolescents from a school sample.MethodsFour hundred and forty-seven students (M = 14.95 years, SD = 0.74, 52% male) completed self-report measures on NSSI, personality traits, and emotional and behavioral problems.ResultsThe past year prevalence of occasional and repetitive NSSI was 4.9% and 6.3% respectively. Repetitive NSSI was significantly associated with female gender, higher levels of age, novelty seeking, harm avoidance, self-transcendence, antisocial behavior, and positive self and lower levels of persistence and self-directedness in univariate analyses. However, multivariate logistic regression analyses indicated that only high levels of antisocial behavior and low levels of self-directedness significantly predicted repetitive NSSI.ConclusionsThe association between a lack of self-directedness and NSSI emphasizes the significance of targeting self-directedness in psychotherapy by strengthening self-awareness, affect tolerance and emotion regulation, as well as establishing and pursuing long-term goals.     

Temperament and character inventory (TCI) personality profile in metamphetamine abusers: a controlled study.

We applied the temperament and character inventory (TCI) personality questionnaire in 41 inpatients dependent on metamphetamine, and 35 controls. Novelty seeking, harm avoidance and self-transcendence were significantly higher, and persistence, self-directedness and cooperativeness were significantly lower in the patients than in the healthy volunteers. The detected differences may be important for prevention and treatment.     

Exploring personality clusters among parents of ED subjects. Relationship with parents' psychopathology,attachment, and family dynamics

Background

Eating disorders are some of the most difficult mental disorders to treat and manage. Family interacts with genetic dispositions and other pathogenic factors, and may influence the outburst, development and outcome of EDs. The present study explores with a cluster analysis the personality traits of parents of ED subjects.

Methods

One-hundred-eight mothers and 104 fathers were tested with Temperament Character Inventory (TCI), Eating Disorder Inventory-2 (EDI-2), State–Trait Anger Expression Inventory (STAX), Family Assessment Device (FAD), Attachment Style Questionnaire (ASQ), Symptom Questionnaire (SQ), Psychological Well-Being scales (PWB). The cluster distribution of parents based on personality traits was explored. Parents' clusters TCI scores were compared as regards personality, psychopathology, attachment and family features. Cross distribution of temperament and character clusters in mothers and fathers, among couples and ED diagnoses of the daughters was explored.

Results

Two clusters of mothers and fathers were identified with temperament clustering. Character traits led to two mothers and three fathers clusters. Mothers temperament cluster 1 (MTC1) correspond to a explosive/adventurous profile, MTC2 to a cautious/passive-dependent profile. Fathers temperament cluster 1 (FTC1) was explosive/methodic, FTC2 was independent/methodic. Character clustering distinguished very immature mothers (MCC1) and majority (65%) of character mature mothers with low self-transcendence (MCC2). A third of fathers was severely immature (FCC1), a third impaired as regards relationships (poor cooperativeness and self-transcendence; FCC2), and one third character mature fathers with low self-transcendence (FCC3). Each cluster evidences specific psychopathology and attachment characteristics. FTC1 was more frequently associated with character immaturity. No significant clusters' cross correlation was found in parental couples.

Conclusion

Parents' clusters analyze in depth the univocal picture of prototypical mothers and fathers of EDs. Parents not disturbed as regards personality traits are not exceptions. Since EDs are multifactor disorders family dynamics related to parents' personality may be very relevant or even marginal in their pathogenesis. Conversely, parenting may be negatively influenced by relatively marginal personality malfunctions of parents. The clustering approach to the complexity of personality-related dynamics of ED families improves the picture of ED parents. Psychoeducational, counseling and psychotherapeutic family interventions should consider the specific underlying personality of parents.     

Personality and attempted suicide. Analysis of anger, aggression and impulsivity

Suicide is one of the leading causes of death worldwide, mortality from suicide being approximately 2%. Attempted suicide appears to be a major risk factor for suicide completion. Anger, aggression and impulsivity are personality traits associated with suicide attempt. In this study we analysed a part of a previously reported sample in order to test anger, impulsivity and temperament/character scales as predictors of aggression and self-aggression in suicide attempters and to compare anger- and aggression-related traits between impulsive and premeditated suicide attempts as well as between violent and non-violent suicide methods.One-hundred-eleven consecutively admitted inpatients with a lifetime history of attempted suicide were assessed for anger (State-Trait Anger Expression Inventory, STAXI), aggression (Questionnaire for Measuring Factors of Aggression, FAF) and temperament/character (Temperament and Character Inventory, TCI).Higher aggression scores, as measured by FAF, were predicted by being male, meeting criteria for borderline personality disorder and having higher angry temperament scores as assessed by STAXI; low cooperativeness was also associated with aggression but not after controlling for STAXI scales. TCI dimensions associated with self-aggression were high harm avoidance, high impulsivity and low self-directedness; state anger, inwardly directed anger and inhibition of aggression were also predictors of self-aggression.In conclusion, impulsivity and harm avoidance have emerged as temperament dimensions independently associated with self-aggressive tendencies in personality. Such interactions could explain the correlation between temperament and suicidality but further research is needed. Anger and self-directedness appear to have some effects on suicide attempt.     

Cloninger's temperament and character dimensions of personality in patients with major depressive disorder

In this present study, we examined the relationship between the Cloninger's dimensional psychobiologic model of personality and depression in an outpatient population with major depressive disorder. Eighty-one depressed outpatients (67 women, 14 men) and 51 healthy controls (35 women, 16 men) filled out the Turkish version of the Temperament and Character Inventory (TCI). Depression severity was evaluated by using the 17-item Hamilton Depression Rating Scale and the 21-item Beck Depression Inventory. Depressed patients exhibited statistically significant higher scores for harm avoidance and lower scores for self-directedness compared to healthy controls. Sentimentality (RD1) and dependence (RD4) subscale scores of reward dependence and spiritual acceptance (ST3) subscale of self-transcendence were significantly higher; attachment (RD3) subscale of reward dependence, responsibility (SD1), purposefulness (SD2), resourcefulness (SD3), and congruent second nature (SD5) subscales of self-directedness were significantly lower in the depressed group. In the depressed patient group, main effects of sex were significant for reward dependence and cooperativeness; the scores of both dimensions were higher for women. The Beck Inventory was positively correlated with harm avoidance and negatively correlated with novelty seeking and self-directedness dimensions (P < .05). The duration of depression (16.33 ± 20.18 months) or the mean onset age of depression (28.68 ± 8.11 years) did not show significant correlations with TCI scales. This study confirms the relationship between harm avoidance and depression and suggests a relationship between self-directedness and depression.
