Abstract
Background and aims The main aim of this study was to analyze and describe the clinical characteristics and shared personality traits in different impulsivity-compulsivity spectrum disorders: substance use disorders (SUD), gambling disorder (GD), and bulimia nervosa (BN). The specific aims were to compare personality differences among individuals with pure SUD, BN with and without SUD, and GD with and without SUD. In addition, we assessed the differential predictive capacity of clinical and personality variables in relation to diagnostic subtype. Methods The sample comprised 998 subjects diagnosed according to DSM-IV-TR criteria: 101 patients were diagnosed with SUD, 482 with GD, 359 with BN, 11 with GD + SUD, and 45 patients with BN + SUD. Various assessment instruments were administered, as well as other clinical measures, to evaluate their predictive capacity. Results Marked differences in personality traits were observed between groups. Novelty seeking, harm avoidance, self-directedness, cooperation, and self-transcendence best differentiated the groups. Notably, novelty seeking was significantly higher in the two dual pathology subgroups. Patients with dual pathology showed the most dysfunctional personality profiles. Discussion and conclusion Our results indicate the existence of shared dysfunctional personality traits among the groups studied, especially in novelty seeking and self-directedness.

Abstract
Although suggested as an important contributor to the development and maintenance of eating disorders, temperament has not previously been studied adopting a meta-analytical approach. We therefore pooled data (N = 14 studies; N = 3315 cases, N = 3395 controls) on Cloninger's temperament traits (novelty seeking, harm avoidance, reward dependence and persistence) in anorexia nervosa (AN), bulimia nervosa (BN), binge eating disorder (BED) and eating disorders not otherwise specified. Persistence was significantly higher than in the controls in all eating disorders except for BED the highest levels being observed in AN. Correspondingly, the highest effect sizes for harm avoidance were seen in AN. Novelty seeking was significantly elevated relative to the controls only in BN. Harm avoidance was significantly lower, and reward dependence was significantly higher in individuals who had recovered from AN than in those who remained ill. Future studies with a longitudinal design are needed to explore the temporal relationships between eating disorders and temperament traits.

Abstract
OBJECTIVES The aims of this study were the following: to identify perceptions of patients with anorexia nervosa (AN) and their siblings regarding differential experiences within and external to the family including sibling interactions, parental treatment, relationships with peers and events that are unique to each sibling; (2) to compare how patients and their siblings perceive eating disorder symptoms, parental affection/control, social support and stigma; and (3) to test associations with family functioning for patients with AN and their siblings. METHOD A total of 26 patients paired with their siblings were recruited from an Eating Disorder Program and administered standardized instruments measuring different experiences within and external to the family, the impact of eating disorder behaviours, stigma, social support and family functioning. RESULTS Patients rated high on the differential experience of jealousy in contrast to their siblings. Patients scored higher than their siblings on eating symptoms, whereas siblings scored higher on social support. The impact of AN on the family, stigma towards the individual and family, and social support accounted for 37% of the variance in family functioning from the sibling perspective after controlling for age and gender. Of these variables, impact of AN on the family made the largest contribution. DISCUSSION Family-based and sibling-based interventions that aim to reduce the effects of the illness on the sibling relationship and the family are recommended.

Abstract
This article reports on a meta-analysis of Cloninger's temperament dimensions (novelty seeking, harm avoidance, reward dependence, and persistence) in individuals with lifetime psychiatric disorders compared with controls and on interdisorder comparisons between these disorders. Nine disorders from 75 studies were included in the meta-analyses. The most consistent feature was elevated harm avoidance: compared with the controls, harm avoidance was higher in all diagnostic groups studied except for those with alcohol use disorders. The increase in effect sizes in harm avoidance scores varied from a very large (d = 2.66) in social phobia to a small effect (effect size, d = 0.29) in alcohol use disorders. In other dimensions, differences between cases and controls were relatively small. However, in pairwise comparisons, notable differences also in other dimensions emerged: in novelty seeking, the lowest scores were in social phobia (d = -0.87) and the highest in bulimia nervosa (d = 0.33); in reward dependence, the lowest scores were in schizophrenia (d = -0.36) and the highest in social phobia (d = 0.12); and in persistence, the lowest scores were in social phobia (d = -0.30) and the highest in anorexia nervosa (d = 0.49). The provided data should be taken into account in the future studies on suggestive vulnerability markers for psychiatric morbidity.

Abstract
OBJECTIVE The role of perceived non-shared environmental influences and personality traits in the risk of developing bulimia nervosa (BN) was compared in 40 women with BN and their non-eating disordered sisters. METHODS The two sisters were compared for (a) eating pathology, (b) perceived non-shared environmental factors (differential family relationships, developmental teasing, traumatic experiences), (c) personality traits (impulsivity, affective instability, narcissism), and (d) psychopathology (anxiety, depression). RESULTS Specific perceived non-shared risk factors (e.g. perceptions of teasing), nonspecific non-shared risk factors (e.g. insecure paternal attachment) and personality traits (e.g. narcissism) distinguished women with BN from sisters. In the final logistic regression, insecure paternal attachment predicted the risk for BN, while trends were apparent for narcissism and developmental teasing after controlling for psychopathology. CONCLUSIONS Our correlational cross-sectional design does not allow for investigation of direction of effects. However, it is an important first step in identifying possible perceived non-shared environmental influences and personality traits that may constitute vulnerability factors predisposing individuals to the development of BN. Findings are discussed in the light of existing models of risk factors for the etiology of BN.

The dynamic relationship of parental personality traits with the personality and psychopathology traits of anorectic and bulimic daughters. Compr Psychiatry 2009; 50:232-9. [PMID: 19374967 DOI: 10.1016/j.comppsych.2008.07.010] [Citation(s) in RCA: 30] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 05/07/2008] [Revised: 07/28/2008] [Accepted: 07/30/2008] [Indexed: 01/08/2023] Open
Abstract
OBJECTIVE Parenting and family dynamics influence the emergence, development, and maintenance of eating disorders (EDs). Although family interventions are relevant for therapeutic programs, knowledge of the relationship between parental personality traits and the eating psychopathology of daughters is scarce. This study explored the personality and psychopathology of women with EDs and correlated them with parental personality traits. METHOD The personality and eating psychopathology traits of 38 restricter anorectics, 30 bingeing/purging anorectics, 37 bulimics, and their parents' personality traits (87 fathers and 97 mothers) were measured with the Temperament and Character Inventory, the Clinical Global Impression Scale, the Eating Disorders Inventory-2, and the Beck Depression Inventory. The results were compared with matched controls (54 women, 50 fathers, 54 mothers). Personality and psychopathology were correlated with multiple regression. RESULTS Women with ED displayed high harm avoidance and low self-directedness, whereas restricter anorectic women had high persistence. Low persistence was common in fathers of daughters across all EDs. Fathers of restricter anorectics were highly harm avoidant. Fathers of both anorectic subtypes and mothers of bulimic women displayed low self-directedness. Parental personality traits were linearly correlated with their daughter's personality and psychopathology, but the correlation differed among EDs. CONCLUSION Parents of eating-disordered participants displayed personality characteristics that differed from controls and, among ED subgroups, these differences were related to their daughter's personality and psychopathology. The linear correlation did not fully explain the relationship of the parental personality traits to the presence of their daughter's ED, suggesting that a more complex personality-based family dynamic is involved. A Temperament and Character Inventory profile of the entire family may be used in the planning of family treatment.

Abstract
Recent advances in personality theory indicate that there are distinct constructs that dispose individuals to rash action and risky behavior, as opposed to one broad trait of impulsivity. Two are emotion based, two represent deficits in conscientiousness, and one is sensation seeking. Previous studies of impulsivity and its relationship to bulimia nervosa have yielded mixed findings. The authors applied this advance in personality theory to the study of bulimia nervosa (BN) to test the hypothesis that the emotion-based disposition of negative urgency (the tendency to act rashly when distressed) relates most strongly to BN symptoms. A meta-analysis of 50 articles indicated the following. Negative urgency had by far the largest effect size (weighted r=.38), followed by sensation seeking (weighted r=.16); lack of planning (weighted r=.16) and lack of persistence (weighted r=.08). Methodological moderators of the effect of distinct traits on BN symptoms were the use of scales that precisely measured one construct as opposed to general impulsivity scales that measured several constructs, clinical vs. non-clinical samples, and whether or not the personality scale was translated from its original language or not. Negative urgency appears especially important for BN; more broadly, researchers should consider the role of emotion-based dispositions to rash acts in their risk theories.

Abstract
OBJECTIVES To investigate the differential profile of early family life events associated with lifetime anorexia nervosa (AN), bulimia nervosa (BN), and major depression (MD). METHOD Only data from the monozygotic twins (n = 622) were examined from a community sample of female twins who had participated in three waves of data collection. Eating disorder and MD diagnoses were ascertained from the Eating Disorder Examination at Wave 3 and interview at Wave 2 respectively. Early family events were ascertained from self-report measures at Waves 1 and 3. Two case control designs were used, including a comparison of women: (1) who had lifetime AN, BN, MD, and controls, and (2) twin pairs discordant for either AN, BN, or MD (where the unaffected cotwin formed the control group). RESULTS Across the two types of designs, compared to controls, both AN and BN were associated with more comments from the family about weight and shape when growing up. AN was uniquely associated with higher levels of paternal protection while BN was associated with higher levels of parental expectations. CONCLUSION While some overlap among early life events was indicated, especially related to parental conflict and criticism, there was evidence to support some degree of nonoverlap among life events associated with AN, BN, and MD.

Abstract
OBJECTIVE The objective of the study was to assess the predictive value of personality profiles to classify individuals with bulimia nervosa (BN), pathological gambling (PG), and a nonpsychiatric comparison group while controlling for sex. METHODS The sample comprised 270 BN (241 women, 29 men), 429 PG (42 women, 387 men), and 96 comparison (nonpsychiatric) subjects (35 women, 61 men). All patients were consecutively admitted to our Psychiatry Department and were diagnosed according to the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, Text Revision criteria. We administered the Temperament and Character Inventory-Revised as well as other clinical indices. Multinomial and binary logistic regression models adjusted for age and stratified by sex were used to assess the predictive value of personality in relation to group status. RESULTS In comparison to controls, high Novelty Seeking (P < .001) was specifically associated with a diagnosis of PG. Independently of sex, low Self-Directedness was associated with both BN (P < .001) and PG (P < .001). Some sex-specific differences were also observed; namely, women with BN and PG displayed higher Harm Avoidance and Cooperativeness than control women, whereas men with PG reported higher Reward Dependence and Persistence than control men. CONCLUSIONS Our results suggested that, whereas there are some shared personality traits between BN and PG when compared with healthy controls, there are also some sex- and diagnostic-specific personality traits that weigh against the consideration of BN as an impulse control disorder.

Abstract
In recent years a number of studies of personality have been performed in subjects with Eating Disorders (EDs) to investigate the clinical differences between controls and ED patients and among EDs subtypes, and its role in the development and course of symptoms. The Tridimensional Personality Questionnaire (TPQ) and the Temperament and Character Inventory (TCI) have been widely used at this purpose, allowing the description of specific temperament and character profiles for EDs. High Harm Avoidance (HA) and low Self-Directedness (SD) are shared by all EDs. Slight differences on some facets have been found among ED subgroups. Nevertheless, HA is influenced by mood and both high HA and low SD are personality traits shared by many mental disorders, whose specificity is rather low. Restrictor anorectics are characterized by high Persistence (P) and a relatively higher SD, and bulimics by higher Novelty Seeking (NS) and the lowest SD, while binge/purging and purging anorectics share some traits with anorexia and some with bulimia. Though current data justify the discrimination among anorexia subtypes, they are not in contrast with the thesis of a continuum in ED personality traits. Since some personality traits display a prognostic value with regard to therapy and clinical outcome, further studies are needed on treatments and prognostic factors in EDs. Moreover, studies attempting to define the neurobiological and genetic correlates of temperament should be supported by clinical pharmacological trials.

Abstract
The goal of the current study was to examine the relationship between core beliefs and a history of eating disorders using a retrospective design. Sixty-three university students completed self-report measures assessing current depressive symptoms. They also completed a semistructured interview assessing current and past histories of eating disorders. The presence of core beliefs was identified through an examination of participants’ life stories. Core beliefs were associated with past histories of both anorexia and bulimia nervosa, even after controlling for current depressive symptoms and eating disorders. Further analyses revealed that core beliefs centering around themes of disconnection and rejection, other-directedness, and overvigilance and inhibition were associated with past histories of anorexia nervosa, whereas core beliefs centering around themes of disconnection and rejection, impaired limits, and overvigilance and inhibition were associated with past histories of bulimia nervosa. These findings provide preliminary support for recent theoretical models highlighting the potential importance of core beliefs in the etiology of eating disorders.

Abstract
Scale scores on the Tridimensional Personality Questionnaire (TPQ)-novelty seeking (NS), harm avoidance (HA), and reward dependence (RD)-can predict response to antidepressants. This study examined 89 patients with Bipolar Disorder (I, II) or Major Depressive Disorder, both with recurrent winter seasonal pattern. The TPQ was administered while the patients were depressed, following 10-14 days of bright light therapy (30 min, 10,000 lux) and after spontaneous springtime remission. The Structured Interview Guide for the Hamilton Depression Rating Scale-Seasonal Affective Disorder Version (SIGH-SAD) assessed the severity of depression. At baseline, there were no significant differences between diagnostic subgroups or responders and non-responders on the TPQ or SIGH-SAD scales, though baseline RD scores were significantly higher in women than men. Furthermore, neither severity of depression nor magnitude of post-treatment clinical improvement was significantly correlated with baseline TPQ scores. Only HA scores decreased after treatment, with responders showing the greatest effect. HA scores also decreased from the baseline to springtime assessments for the group as a whole, with no difference between responders and non-responders. This is the first study to demonstrate that HA is state- rather than trait-dependent in seasonal affective disorder. The TPQ dimensions of temperament do not predict response to light therapy.

Abstract
OBJECTIVE Nonshared environmental influences are experiences that are unique to siblings reared in the same family. We review studies highlighting the importance of nonshared factors for the development of eating disorders and suggest areas for future research. METHODS Findings from behavioral genetic studies of eating disorders as well as methodological issues are reviewed. RESULTS Twin studies suggest that approximately 17%-46% of the variance in both anorexia nervosa (AN) and bulimia nervosa (BN) can be accounted for by nonshared environmental factors. Studies directly examining these influences are scarce, although initial data indicate that differential paternal relationships, body weight teasing, peer group experiences, and life events may account for the development of eating pathology in one sibling versus another. DISCUSSION Additional research is needed to identify specific nonshared environmental influences on eating disorders such as differential parental and sibling treatment, disparate peer group characteristics, and differential experience of life events such as physical and sexual abuse.

Abstract
Bulimia nervosa is a common eating disorder in adolescent women. Biological, psychological, and social factors are implicated in onset and important in treatment. Diagnosis of the syndrome, but not its subtypes, can be made well using the DSM-IV system. Screening tools, laboratory findings, and physical findings can be helpful in making the diagnosis. Comorbid disorders include affective disorders, addictive disorders, anxiety disorders, personality disorders, and anorexia nervosa. The etiology of bulimia nervosa is complex, with biologic, psychological, social, and family factors, which likely differ somewhat from patient to patient. Treatment, accordingly, should be comprehensive, individualized, and multifaceted. Many patients respond well to the use of an antidepressant, and cognitive-behavioral therapy is a useful approach for many patients. Combining these two treatments seems to be a good strategy. Environmental and family issues also need to be addressed. Many patients are treated insufficiently. More research on bulimia nervosa specific to adolescence is needed.

Abstract
A distinctive personality type, characterized by introversion, inflexibility, and low novelty seeking, has been suggested to be associated with Parkinson's disease. To test the hypothesis that Parkinson's disease is associated with a specific dopamine-related personality type, the personality structures of 61 unmedicated Parkinson's disease patients and 45 healthy controls were examined. Additionally, in 47 Parkinson's disease patients, the dopaminergic function in the brain was directly measured with 6-[(18)F]fluoro-l-dopa ((18)F-dopa) positron emission tomography (PET) with MRI coregistration. The novelty-seeking personality score, supposedly associated with the parkinsonian personality, was slightly lower in the Parkinson's disease group compared with controls, but it did not have a significant relationship with (18)F-dopa uptake in any of the brain regions studied (r = -0.12 to 0.11, P > 0.15). The harm-avoidance personality score, associated with anxiety and depression, was clearly increased in patients with Parkinson's disease and it had a paradoxical, highly significant positive correlation with the (18)F-dopa uptake in the right caudate nucleus (r = 0.53, P = 0.04, Bonferroni corrected for 220 comparisons). Although the results of this study are not in disagreement with the concept of low-novelty-seeking personality type in Parkinson's disease, the personality type does not seem to be dopamine dependent. The correlation between the personality trait of harm avoidance and (18)F-dopa may reflect a specific feedback circuitry of neurotransmitters that is associated with negative emotionality in Parkinson's disease.
