The relationship among three models of personality psychopathology: DSM-III-R personality disorder, TCI scores and DSQ defences.

BACKGROUND: Current systems of describing personality pathology have significant shortcomings. A polydiagnostic approach is used to study the relationship between psychological, psychoanalytical and psychopathological models of personality. METHODS: The subjects were 256 patients enrolled in treatment studies of major depression and bulimia nervosa. Subjects were assessed using the Temperament and Character Inventory (TCI), the Defense Style Questionnaire (DSQ) and the Structured Clinical Interview for DMS-III-R personality disorders (SCID-II). RESULTS: Subjects had high rates of DSM-III-R personality disorders with 52% having at least one personality disorder. Cluster A personality disorders were correlated with low reward dependence, high harm avoidance and low self-directedness and cooperativeness. Cluster B personality disorders were related to high novelty seeking and low self-directedness and cooperativeness. Cluster C personality disorders were correlated with high harm avoidance and low novelty seeking and low self-directedness. Immature defences were related to DSM-III-R personality symptoms, but individual defences were not related to personality clusters in a predictable way. Immature defences were strongly related to low self-directedness and cooperativeness. Both TCI self-directedness scores and immature defence scores were moderately predictive of the presence and number of personality disorders. CONCLUSION: A widely accepted clinical nosology (DSM-III-R personality disorders) rated using a clinical interview correlates reasonably predictably with two theoretical models derived from different paradigms and rated using self-reports. This might be seen as providing concurrent validity for all three models. However, serious methodological shortcomings confront studies of this type, including sample selection and measurement of personality dysfunction. One way to begin to resolve these problems is to study which personality measures are best related to treatment response and prognosis.     

High harm avoidance and low self-directedness in euthymic young adults with recurrent, early-onset depression

BACKGROUND: The personality dimensions of harm avoidance (HA) and self-directedness (SD), as measured by the Temperament and Character Inventory (TCI), have been widely associated with depression and there is preliminary evidence that they may represent trait markers for depression. However, many studies in this area are limited by the use of heterogeneous samples of depressed patients and by the confounding effect of depressed mood during personality testing. The current study compares TCI personality dimension scores in a group of euthymic young adults with recurrent early-onset major depressive disorder (RE-MDD) to well-matched euthymic controls. METHODS: Fifty-two young adults with a past history of RE-MDD were recruited from consecutive referrals to a psychiatric clinic at a university health service. Eighty nine controls were also recruited. Euthymia was established in patients by a score of less than 9 on the Hamilton Rating Scale for Depression (HRSD) and in controls by a Becks Depression Inventory (BDI) score of less than 10. All participants completed the TCI-125. RESULTS: Patients and controls were well matched in terms of sociodemographic profile. Euthymic RE-MDD patients scored significantly higher than controls on the temperament dimension of harm avoidance (HA; mean score 14.5 versus 7.8, p<0.0001) and significantly lower than controls on the character dimension of self-directedness (SD; mean score 14.1 versus 19.9, p<0.0001). Covariance analysis suggested that both HA and SD contributed independently to the familial risk of depression. LIMITATIONS: Subjects and controls all came from relatively affluent social backgrounds-these findings may not generalise to more socioeconomically diverse populations. The possibility of a 'scarring effect' of depressive episodes on self-reported personality dimension scores cannot be excluded. CONCLUSIONS: High HA and low SD represent trait markers for liability to recurrent major depressive disorder in young adults. Further research is needed to replicate these findings and to assess the contribution that the experience of depressive episodes makes to self-reported personality dimension scores.     

The temperament and character inventory in major depression

Patients admitted for pharmacological treatment of a non-bipolar major depressive episode completed the Temperament and Character Inventory (TCI) prior to and after at least 6 weeks of treatment. Treatment with various antidepressants resulted in a 43% reduction of symptomatology. Scores on the harm avoidance dimension before and after treatment appeared to be significantly higher as compared to Dutch normative data. TCI scores did not predict response to treatment or show a change during treatment. It is concluded that, in this group of patients, the personality dimension harm avoidance is a trait factor without predictive value for antidepressant responsiveness.     

Personality characteristics of women before and after recovery from an eating disorder

BACKGROUND: Previous studies of personality characteristics in women with eating disorders primarily have focused on women who are acutely ill. This study compares personality characteristics among women who are ill with eating disorders, recovered from eating disorders, and those without eating or other Axis I disorder pathology. METHOD: Female participants were assessed for personality characteristics using the Temperament and Character Inventory (TCI): 122 with anorexia nervosa (AN; 77 ill, 45 recovered), 279 with bulimia nervosa (BN; 194 ill, 85 recovered), 267 with lifetime histories of both anorexia and bulimia nervosa (AN + BN; 194 ill, 73 recovered), 63 with eating disorder not otherwise specified (EDNOS; 31 ill, 32 recovered), and 507 without eating or Axis I disorder pathology. RESULTS: Women ill with all types of eating disorders exhibited several TCI score differences from control women, particularly in the areas of novelty-seeking, harm avoidance, self-directedness, and cooperativeness. Interestingly, women recovered from eating disorders reported higher levels of harm avoidance and lower self-directedness and cooperativeness scores than did normal control women. CONCLUSIONS: Women with eating disorders in both the ill and recovered state show higher levels of harm avoidance and lower self-directedness and cooperativeness scores than normal control women. Although findings suggest that disturbances may be trait-related and contribute to the disorders' pathogenesis, additional research with more representative community controls, rather than our pre-screened, normal controls, is needed to confirm these impressions.     

The relationship of dysfunctional attitudes to personality in depressed patients.

AIM: To examine the relationship between dysfunctional attitudes and personality in depressed patients. METHOD: One hundred depressed patients completed both the Dysfunctional Attitudes Scale (DAS) and the Temperament and Character Inventory (TCI). RESULTS: Scores on the DAS correlated with duration of depression, age of onset of depression, age, harm avoidance and self-directedness. In a multiple regression analysis three measures explained 45% of the DAS score. These were duration of depression, reward dependence and self-directedness. In both the univariate analyses and multiple regression the strongest predictor of dysfunctional attitudes was the character dimension of self-directedness. CONCLUSION: The character dimension of self-directedness in the TCI which assesses an individuals' self-concept, relates highly with the dysfunctional attitudes score on the DAS. Given that the TCI assesses personality within a broader framework of a psychobiologic and developmental model, self-directedness may have a wider application as a measure of self-concept than the DAS.     

Temperament and character inventory dimensions as a predictor of response to antidepressant treatment in major depression

BACKGROUND: Cloninger's theory of personality, including 4 temperament dimensions and 3 character dimensions, is one of the most noteworthy theories in recent years. Several studies have explored temperament dimensions as a predictor of response to antidepressant treatments in major depression, but these have provided inconsistent results. The present study explored temperament as well as character dimensions, as measured by the Temperament and Character Inventory (TCI), as possible predictors of response to maprotiline, the most-widely prescribed antidepressant in Japan. METHODS: 86 consecutive patients with major depression underwent a 16-week open trial of maprotiline. They filled out the TCI at baseline, and were followed up at weeks 8 and 16 by using the Hamilton Rating Scale for Depression. RESULTS: Hierarchial logistic regression analyses demonstrated that response to maprotiline was significantly predicted by the cooperativeness score at the 8-week outcome assessment, and by the self-directedness score at the 16-week outcome assessment, after controlling the possible effects of clinical variables on the response. There was no evidence that either temperament dimensions or their 2-way interactions significantly predicted the response. LIMITATIONS: Large replication studies with other antidepressants are needed for generalizing the results in this study. CONCLUSIONS: The results in this study regarding temperament dimensions seem consistent with findings in previous studies, which are, as a whole, inconsistent with each other. It is suggested that character dimensions (particularly cooperativeness and self-directedness), rather than temperament dimensions, may be important predictors of response to antidepressants. Antidepressants may differ in the personality configurations that predict optimal responses.     

The association of major depressive episode and personality traits in patients with fibromyalgia

INTRODUCTION:

Personality traits have been associated with primary depression. However, it is not known whether this association takes place in the case of depression comorbid with fibromyalgia.

OBJECTIVE:

The authors investigated the association between a current major depressive episode and temperament traits (e.g., harm avoidance).

METHOD:

A sample of 69 adult female patients with fibromyalgia was assessed with the Temperament and Character Inventory. Psychiatric diagnoses were assessed with the Mini-International Neuropsychiatric Interview severity of depressive symptomatology with the Beck Depression Inventory, and anxiety symptomatology with the IDATE-state and pain intensity with a visual analog scale.

RESULTS:

A current major depressive episode was diagnosed in 28 (40.5%) of the patients. They presented higher levels of harm avoidance and lower levels of cooperativeness and self-directedness compared with non-depressed patients, which is consistent with the Temperament and Character Inventory profile of subjects with primary depression. However, in contrast to previous results in primary depression, no association between a major depressive episode and self-transcendence was found.

CONCLUSIONS:

The results highlight specific features of depression in fibromyalgia subjects and may prove important for enhancing the diagnosis and prognosis of depression in fibromyalgia patients.     

A possible association between the Val158Met polymorphism of the catechol-O-methyl transferase gene and the personality trait of harm avoidance in Japanese healthy subjects

Catechol-O-methyltransferase (COMT) is an enzyme that degrades various biogenic amines, which have been hypothesized to be associated with personality traits. We investigated a possible relationship between the COMT Val158Met polymorphism and personality traits assessed by the Temperament and Character Inventory (TCI) in 139 healthy subjects in a Japanese population. The number of Met alleles of the COMT Val/Met genotype tended to relate to harm avoidance (HA) scores parametrically, while no significant difference was observed between genotype groups in either novelty seeking, reward dependence, persistence, self-directedness, cooperativeness or self-transcendence. These results suggest that the Val/Met polymorphism of the COMT gene may play a role in HA in Japanese population.     

Bipolar disorder: I. Temperament and character

BACKGROUND: The nature of the relationship between personality and bipolar affective disorders is an important but unanswered question. METHODS: We have studied personality in bipolar patients by using the Temperament and Character Inventory (TCI). TCI were administered to 100 euthymic bipolar patients and 100 controls from the normal population. RESULTS: Bipolar patients were significantly higher in harm avoidance (HA) and lower in reward dependence (RD), self-directedness (SD), and cooperativeness (CO) than controls. Bipolar patients are more fatigable, less sentimental, more independent, less purposeful, less resourceful, less empathic, less helpful, less pure-hearted, and have less impulse control than controls. Bipolar II patients are more impulsive, more fatigable, less resourceful, and have less impulse control than bipolar I patients. LIMITATIONS: Our results are limited to euthymic bipolar patients and cannot be generalized to affective disorders. CONCLUSIONS: Even when clinically euthymic on lithium maintenance, bipolar patients continue to have a characteristic cognitive deficit. This is in agreement with cognitive theories about cognitive deficits in depression that are regarded as important vulnerability factors in mood disorders.     

Difference in Temperament and Character Inventory scores between depressed patients with bipolar II and unipolar major depressive disorders

Background

Although some core personality variables are known to be characteristic of unipolar or bipolar depression, few studies have compared the personality profile between these two disorders.

Methods

Temperament and Character Inventory (TCI) was employed to assess the personality of 36 depressed patients with bipolar II disorder (BPII), 90 patients with unipolar major depressive disorder (UP), and 306 healthy controls. The TCI was administered during the depressive episode in BPII and UP patients so that the results can be applied in a clinical setting.

Results

Significantly higher scores in harm avoidance (p < 0.0001) and lower scores in self-directedness (p < 0.0001) and cooperativeness (p < 0.05) were observed in both BPII and UP patients compared to controls. Lower novelty seeking in UP patients compared to BPII patients and controls was observed in females (p < 0.0001, p < 0.01, respectively). A significant difference in self-transcendence score was observed between BPII and UP patients in females (p < 0.0005), with higher scores in BPII (p = 0.009) and lower scores in UP (p = 0.046) patients compared to controls. A logistic regression model predicted BPII in depressed females based on novelty seeking and self-transcendence scores with a sensitivity of 89% and a specificity of 73%, but did not accurately predict BPII in males.

Limitations

Patients in our study were limited to those receiving outpatient treatments, and bipolar patients were limited to those with BPII.

Conclusions

Novelty seeking and self-transcendence scores of TCI might be useful in the differentiation of UP and BPII in female patients.     

Is interpersonal sensitivity specific to non-melancholic depressions?

Background: We investigated whether melancholic and non-melancholic Japanese depressive patients differed in regard to a personality feature, interpersonal sensitivity, as measured by the Interpersonal Sensitivity Measure (IPSM). Methods: In addition to 154 normal controls, 66 remitted melancholic patients and 55 remitted non-melancholic patients filled out the IPSM and two widely-used comprehensive personality inventories, the Temperament and Character Inventory (TCI) and the Munich Personality Test (MPT). The subdivision of patients was made according to three major symptom-based criteria for melancholia (those of RDC, DSM-III, DSM-IV). Results: Multivariate and post-hoc univariate analyses of variance revealed significant differences among the three groups in several personality dimensions after Bonferroni's adjustments of P values. While reported scores of both melancholic and non-melancholic patients deviated from normative scores on several personality dimensions, non-melancholic patients reported significantly higher scores on the total IPSM and the 'fragile inner-self' (a subscore of the IPSM) than did normal controls or melancholic depressives. The principal component analysis isolated two factors related to depressive disorders: one factor corresponding to the five IPSM scores; and the other corresponding to harm avoidance, neuroticism and frustration tolerance. The scores on the former factor differentiated non-melancholic depressives from melancholic depressives and normal controls. The scores on the latter factor differentiated both melancholic and non-melancholic depressives from normal controls. Limitations: Prospective studies in which depressive subjects are subdivided into melancholic and non-melancholic subjects will be required to see whether the personality deviations here related to depressive disorders strongly reflect the premorbid personality function. Conclusions: These results indicate that the IPSM scales (particularly, the fragile inner-self scale and the total IPSM scale) are relatively independent of all dimensions included in the two comprehensive personality inventories, and have a capability to describe personality differences between non-melancholic depression and melancholia.     

Personality dimensions harm avoidance and self-directedness predict the cortisol awakening response in military men

To account for individual differences in vulnerability for stress-related disorders, studies have examined the relationship between hypothalamic-pituitary-adrenal (HPA) axis functioning and personality. The present study examined the relationship between the free fraction of cortisol in saliva after awakening and personality as measured with Cloninger's Temperament and Character Inventory [Cloninger, C.R., Przybeck, T.R., Svrakic, D.M., Wetzel, R.D., 1994. The Temperament and Character Inventory (TCI): A Guide to its Development and Use. Washington University, Center for Psychobiology of Personality, St. Louis, MO] in 107 healthy male soldiers. Harm avoidance explained 9% of variance in cortisol levels after awakening (AUCG), and harm avoidance and self-directedness predicted 10% of variance in mean cortisol increase. The cortisol awakening response (CAR) was lower in participants with low scores on harm avoidance, and mean cortisol increase after awakening was higher in soldiers high on self-directedness and harm avoidance. These results show that the CAR is related to personality and that it can be used to examine individual differences in HPA (re)activity.     

Alexithymia and the temperament and character model of personality

OBJECTIVE: In our study we explored the associations between alexithymia (Toronto Alexithymia Scale 20, TAS-20) and the dimensions and subscales of Cloninger's theoretically based and empirically validated psychobiological model of personality to further clarify the relationship between alexithymia and personality traits. METHODS: Psychiatric in- and outpatients (n = 254) were investigated with the TAS-20, the Temperament and Character Inventory (TCI) and the Symptom Check List SCL-90-R to control for the severity of current psychopathology. Correlation and regression analyses were performed. RESULTS: The regression analysis identified the TCI dimensions low self-directedness (SD), low reward dependence (RD) and to a minor degree harm avoidance (HA) as independent predictors for alexithymia. At the level of subscales, interpersonal detachment (RD3), low resourcefulness (SD3), low responsibility and blaming (SD1) and shyness with strangers (HA3) were predictors for alexithymia. The degree of explained variance of the TAS-20 scores by the TCI dimensions and subscales ranged between 43 and 45% whereas the inclusion of the general severity index into the regression models accounted for an additional 5% of the variance. CONCLUSIONS: Alexithymia is best explained by a mixture across different dimensions and subscales within Cloninger's psychobiological model of personality. However, alexithymia is captured only partly by current concepts of personality, and additional contributing psychological and biological factors need to be identified to understand alexithymia more extensively.     

Prefrontal 5-HT2a receptor binding index,hopelessness and personality characteristics in attempted suicide

BACKGROUND: Depression, hopelessness, impaired problem solving capacities and deficient serotonergic functions have been identified as major causes of suicidal behaviour. In general, the relation between biological markers of attempted suicide and psychological functions has been investigated using indirect peripheral markers of, e.g. the serotonergic system. Recently, functional neuroimaging techniques with radioligands allow direct in vivo assessment of the neurobiological status of the central nervous system. METHODS: We studied the binding index of serotonin-(2a) (5-HT(2a)) receptors in the frontal cortex of attempted suicide patients (n=9) and normal controls (n=13) using [123I]5-I-R91150, a highly selective 5-HT(2a) receptor ligand. Moreover, we measured personality characteristics (using Cloninger's Temperament and Character Inventory) and levels of hopelessness (using Beck's Hopelessness Scale), and studied the association between 5-HT(2a) receptor binding index, hopelessness and these personality dimensions. RESULTS: When compared to normal controls, attempted suicide patients had a significantly lower binding potential of frontal 5-HT(2a) receptors, a higher level of hopelessness, a higher score on the temperament dimension harm avoidance and lower scores on the character dimensions self-directedness and cooperativeness. A significant correlation was found between harm avoidance, hopelessness and binding index in the population of patients that attempted suicide. LIMITATIONS: The limited number of patients and potential ingestion of psychotropic drugs may influence the results of the study. CONCLUSIONS: Lower central serotonergic function, hopelessness and harm avoidance are interrelated phenomena, which may increase the probability of the occurrence of attempted suicide.     

Stability of attachment‐related anxiety and avoidance and their relationships with the five‐factor model and the psychobiological model of personality

Objectives. The stability of attachment‐related anxiety and avoidance and their relationship with influential personality models are issues worth further investigation. Studying discriminant validity with respect to aspects of personality deemed as prevalently heritable, such as temperament, is particularly important. Our aims were to examine the stability of attachment dimensions and to study their relationship with psychological distress, the Big Five factors, and temperament and character dimensions. Methods. The Experiences in Close Relationships (ECR) questionnaire, the State‐Trait Anxiety Inventory (STAI), the Zung depression scale (ZDS), the Temperament and Character Inventory (TCI‐125), and the Big Five Questionnaire (BFQ) were administered to 222 undergraduate and graduate students. After 1 month, 115 participants completed again the ECR, the STAI, and the ZDS. Results. Attachment‐related anxiety was modestly correlated with depression and anxiety, while attachment‐related avoidance was modestly correlated with depression. The test–retest reliability of ECR scores was high. Changes in attachment‐related anxiety were not related to changes in depression or anxiety, and changes in attachment‐related avoidance were modestly correlated with changes in depression. In separate multiple regression models also including gender and age, attachment‐related anxiety was correlated with harm avoidance, reward dependence, low novelty seeking, low self‐directedness and low cooperativeness; low energy/extraversion and low emotional stability; attachment‐related avoidance was correlated with low reward dependence and tended to be correlated with low self‐directedness. Conclusions. These findings corroborate the reliability and the convergent and discriminant validity of the ECR, and support the notion that the attachment dimensions are only modestly related to psychological distress and are not redundant with constructs developed within influential personality models such as the five‐factor model and the psychobiological model.     

Eating disorders and eating problems among adolescents with type 1 diabetes: exploring relationships with temperament and character

OBJECTIVE: To determine temperament and character among adolescents with type 1 diabetes with and without disordered eating. METHOD: A clinical sample of 199 adolescents from multiple centers with a mean age of 14.1 (SD, 2.5) years were screened and diagnosed for eating disorders. Assessed were temperament and character as conceptualized by Cloninger, glycemic control, and depression. RESULTS: Adolescent patients with clinical eating disorders or subthreshold eating problems had significantly higher mean scores in harm avoidance and lower mean scores in self-directedness. Harm avoidance remained significant even after controlling for depressive pathology. DISCUSSION: This study is the first to show evidence that among youths (in particular, girls) with type 1 diabetes, there is an association between low self-directedness, high harm avoidance, and the presence of eating, weight, and shape pathology. For these particular youths, important implications for clinical practice are outlined.     

Stability of alexithymia and its relationships with the 'big five' factors, temperament, character, and attachment style

BACKGROUND: Controversy still exists concerning the stability of the alexithymia construct. Also, although alexithymia has been found to be related in a theoretically meaningful way to other personality constructs such as the 'Big Five' factors, few studies have investigated its relationship with influential constructs such as temperament and character, and attachment security. METHODS: Two hundred twenty-one undergraduate and graduate students were administered the Toronto Alexithymia Scale (TAS-20), the State-Trait Anxiety Inventory (STAI), the Zung Depression Scale (ZDS), the Temperament and Character Inventory (TCI-125), the Big Five Questionnaire (BFQ), and the Experiences in Close Relationships (ECR) questionnaire. After 1 month, 115 participants completed again the TAS-20, STAI, and ZDS. RESULTS: Alexithymia was only moderately correlated with depression and anxiety. Both the absolute and relative stability of TAS-20 total and subscale scores was high, and a negligible portion of their change over time was accounted for by changes in depression or anxiety. In separate multiple regression models including also gender, age, depression and anxiety, TAS-20 total and subscale scores were correlated with low energy/extraversion, low emotional stability, openness, low friendliness/agreeableness; harm avoidance, low self-directedness, low cooperativeness, low reward dependence; attachment-related avoidance and anxiety. CONCLUSIONS: Our findings lend support for both absolute and relative stability of alexithymia, corroborate an association between alexithymia and insecure attachment, and contribute to a coherent placing of alexithymia in the broader theoretical network of personality constructs.     

Dropout from brief psychotherapy in anorexia nervosa

BACKGROUND: Dropout from psychotherapy is an important issue that has received little systematic attention. This study investigated the phenomenon of dropout from brief psychotherapy for anorexia nervosa (AN). METHODS: 99 outpatients suffering from AN of the restrictor type (n = 53) or binge/purging type (n = 46) were evaluated. Their clinical and personal characteristics were recorded, and body mass index was calculated for participants. They were administered the Eating Disorder Inventory-II (EDI-II), the State-Trait Anger Expression Inventory (STAXI) and the Temperament and Character Inventory (TCI). RESULTS: Significant differences in some baseline psychopathologic (EDI-II, STAXI) and personality (TCI) variables emerged from the comparison between dropouts and completers. Patients who dropped out of the treatment showed higher levels of anger temperament, anger expression-in and expression-out and lower scores for the dimensions of character (low self-directedness and low cooperativeness). No differences were found between the two groups regarding sociodemographic and clinical variables. CONCLUSIONS: Dropout from brief psychotherapy seems to be related to either psychopathologic or personality aspects, such as the tendency to repress anger, which is encountered also in psychosomatic disorders, and the presence of more compromised dimensions of character, typical of subjects with personality disorders. This study of dropout from brief psychotherapy in AN provided interesting results that will need further confirmation. Possible implications for treatment are addressed.     

A multivariate analysis of 59 candidate genes in personality traits: the temperament and character inventory

Cloninger (Cloninger CR. Neurogenetic adaptive mechanisms in alcoholism. Science 1987: 236: 410-416) proposed three basic personality dimensions for temperament: novelty seeking, harm avoidance, and reward dependence. He suggested that novelty seeking primarily utilized dopamine pathways, harm avoidance utilized serotonin pathways, and reward dependence utilized norepinephrine pathways. Subsequently, one additional temperament dimension (persistence) and three character dimensions (cooperativeness, self-directedness, and self-transcendence) were added to form the temperament and character inventory (TCI). We have utilized a previously described multivariate analysis technique (Comings DE, Gade-Andavolu R, Gonzalez N et al. Comparison of the role of dopamine, serotonin, and noradrenergic genes in ADHD, ODD and conduct disorder. Multivariate regression analysis of 20 genes. Clin Genet 2000: 57: 178-196; Comings DD, Gade-Andavolu R, Gonzalez N et al. Multivariate analysis of associations of 42 genes in ADHD, ODD and conduct disorder. Clin Genet 2000: in press) to examine the relative role of 59 candidate genes in the seven TCI traits and test the hypothesis that specific personality traits were associated with specific genes. While there was some tendency for this to be true, a more important trend was the involvement of different ratios of functionally related groups of genes, and of different genotypes of the same genes, for different traits.     

Early maladaptive schemas,temperament and character traits in clinically depressed and previously depressed subjects

The Young Schema Questionnaire (YSQ) and the Temperament and Character Inventory (TCI) have been suggested as vulnerability markers for depression. One‐ hundred forty clinically depressed subjects(CD), previously depressed subjects(PD) and never depressed (ND) controls completed the YSQ, the TCI and the Beck Depression Inventory. Results showed that CD and PD differed significantly on early maladaptive schemas, temperament and character traits compared with ND. In accordance with previous research, higher levels of harm avoidance and lower levels of self‐directedness were found in CD and in recovered PD. Moreover, CD and PD showed substantial variability in the scores on the YSQ and the TCI when controlling for concurrent depression severity. In multiple regression analyses, YSQ domain scales of disconnection, impaired autonomy, restricted self‐expression and impaired limits emerged as significant predictors of depression severity. Likewise, as concerns TCI higher order scales, high harm avoidance, low self‐directedness and high persistence emerged as significant predictors of depression severity. Harm avoidance was positively related to several early maladaptive schemas (EMSs), whereas self‐directedness was negatively related to a majority of the EMSs. Our findings indicate the presence of maladaptive personality characteristics in CD and PD. Longitudinal studies are needed to establish their causal role in relation to first‐onset and recurrent depression. Copyright © 2009 John Wiley & Sons, Ltd. Key Practitioner Message: ? Early maladaptive schemas, high harm [correction made here after initial online publication] avoidance and low self‐directedness may be a part of vulnerability to depression. ? The finding of these personality characteristics in subjects recovered from depression indicates malfunctioning to some degree. ? Addressing such characteristics in therapy should be considered in order to prevent and treat depression from its relapsing and recurring course.
