Personality dimensions associated with depressive personality disorder.

Depressive personality disorder (DPD) is a historically important construct that requires empirical attention. This study compares 26 subjects with this disorder to 20 non-DPD subjects who have similar histories of longstanding early-onset depression on three personality measures, the Tridimensional Personality Questionnaire (TPQ), NEO-Five Factor Inventory, and Defense Style Questionnaire (DSQ). The samples were demographically similar and had similar rates of comorbid depression and dysthymia. They differed in that DPD subjects scored significantly higher on Harm Avoidance and Neuroticism, and significantly lower on Novelty Seeking, Extroversion, and Adaptive defense mechanisms. Implications for clinical care and nosology are discussed.

Continuity of axes I and II: toward a unified model of personality, personality disorders, and clinical disorders.

In the current standard psychiatric nomenclature, the DSM-IV-TR (APA, 2000), mental disorders are divided into two groups: Clinical Disorders (CDs) and Personality Disorders (PDs), and CD and PD diagnoses are recorded on two separate axes (Axes I and II, respectively). This article considers evidence regarding putative bases for distinguishing between CDs and PDs, and finds that these constructs are more similar than distinct. Links between the domains may be better understood by focusing on how personality connects CDs and PDs. This perspective underlines the need to work toward a more unified model of personality, PDs, and CDs in research and in future editions of the DSM.

Relationships between self-regulation and personality scores of persons with Down syndrome.

This study examined the associations of self-regulation (scores on self-assertion and self control) with personality traits for 76 persons with Down syndrome. Analysis shows self-assertion scores were correlated with scores for all personality traits. The correlations were significant with Emotionality and Playfulness for people with Down syndrome but not for those without Down syndrome (n=40). Self-control scores significantly correlated with scores on controlling and attachment for both groups. Emotionality was related to scores on self-control for students without Down syndrome but not for those with Down syndrome.

Relationship between the basic personality inventory and the NEO-Personality Inventory in a nonpatient sample.

The relation between psychopathology measured by Jackson's 1989 Basic Personality Inventory and personality dimensions measured by Costa and McCrae's 1985 NEO-Personality Inventory was investigated in a nonpatient sample of 457 female subjects. The results contribute to the validation of both instruments and agree with the relevant findings reported in the literature. They also provide support for the cross-cultural invariance of these instruments.

Investigating the relationship between the Millon Adolescent Personality Inventory and the Personality Inventory for Children with a sample of learning disabled adolescents.

The present study involved a preliminary evaluation of the correlations between subscales on the Personality Inventory for Children and the Millon Adolescent Personality Inventory with 25 learning disabled adolescents. Analysis yielded a number of significant correlations between these two scales, using the Personality Inventory for Children as the anchor scale, and showed that these adolescents as a group scored within clinically acceptable ranges on both diagnostic scales. Both scales need further psychometric and clinical investigation, and as such, the limitations of the study and the research needed are addressed, including the need for more multitrait, multimethod studies.

Personality characteristics in heroin addicts and nonaddicted prisoners using the Edwards Personality Preference Schedule.

The present study compares the self-reported personality characteristics of heroin addict and nonaddict prisoners using the Edwards Personality Preference Schedule (EPPS) which was corrected for social desirability. Seventy pairs of addicted and nonaddicted criminal offenders were matched for age, education, intelligence, and home environment. The addicted offenders were identified by the pattern of their response to the EPPS as reflected by the significant multivariate results. In addition, significant univariate differences consistent with those previously reported were found. Addicted criminals had stronger succorance, heterosexuality, and aggression needs and less abasement and endurance needs than nonaddicted offenders. Age, educational achievment, intelligence,and home environment had little influence on the prisoners' response to this self-report personality inventory.

[Validation of the French version of the Raine Schizotypal Personality Disorder Questionnaire--categorial and dimensional approach to schizotypal personality traits in a normal student population].

Most of existing self-report measures of schizotypal personality assess only few of the nine traits of Schizotypal Personality Disorder (SPD) according to DSM III-R or DSM IV. The Raine's Schizotypal Personality Questionnaire (SPQ) is one of the most widely used questionnaire for SPD diagnosis. This well adapted tool for screening SPD in large samples from general population allows simple and quick evaluations by the mean of 74 items and nine sub-scales exploring DSM IV criteria of the trouble. With the original sample of American students, Raine found SPQ to have high internal reliability (0.91) and reported cutoffs for the top and the bottom ten percents of SPQ scores at respectively 41/74 and 12/74. We reported here the validation study of the French version of the SPQ in a sample of 232 students (males: n = 107; females: n = 125; mean age: 21.17 +/- 1.47; mean educational level: 13.36 +/- 1.06). The French version has high internal reliability (SPQ total: Cronbach's alpha = 0.91; SPQ nine subscales: Cronbach's alpha = 0.57 to 0.76). The ten percent high and low cutoff scores on the distribution of SPQ scores are respectively 40/74 and 7/74 for the total sample. However, gender differences are observed: 38/74 and 9/74 for females; 42/74 and 6/74 for males. A Principal Component Analysis (PCA) confirms the high internal reliability. Moreover, PCA evidences a three-factor model of schizotypy reflecting "positive or cognitive-perceptual", "negative or social-interpersonal", and "disorganization" latent factors. These results replicate previous works on the topic with the same instrument.

Examining the relationship between clinical concepts of personality disorder and dimensional measures of normal personality.

Psychiatric epidemiologists acknowledge the value of combining psychometric and clinical diagnostic approaches. However, in the description of personality disorders, the approaches have developed independently of one another. In two recent studies, the Socialization scale of the California Psychological Inventory and the E and N scales of the Eysenck Personality Inventory were found to be compatible with broad clinical concepts of personality disorder. It is suggested that these scales could be employed in epidemiological studies as screening tests.

[Bipolar patients in remission: personality disorders and changes in personality].

81 remitted patients with bipolar affective disorder were examined 20 months after the last discharge from hospital, for personality disorders and other personality deviations, which could be important for their way of coping. There was a high frequency of narcissistic, histrionic and borderline traits and, especially in the bipolar schizoaffective subgroup, of schizoid and related traits. Patients with few former episodes seemed to be "syntonic". Bipolar patients with a longer duration of illness showed an increasing resignative and subdepressive change of feelings and attitudes, whereas the schizoaffective patients in the long term showed a hypomanic alteration. The personality changes of bipolar patients occur during the "free intervals" and are mediated by social interaction, whereas the alteration of some bipolar schizo-affective seems to be caused directly by their illness.

The International Personality Disorder Examination. The World Health Organization/Alcohol, Drug Abuse, and Mental Health Administration international pilot study of personality disorders.

BACKGROUND: One of the aims of the World Health Organization/Alcohol, Drug Abuse, and Mental Health Administration joint program on psychiatric diagnosis and classification is the development and standardization of diagnostic assessment instruments for use in clinical research worldwide. The International Personality Disorder Examination (IPDE) is a semistructured clinical interview compatible with the International Classification of Diseases, Tenth Revision, and the DMS-III-R classification systems. This is the first report of the results of a field trial to investigate the feasibility of using the IPDE to assess personality disorders worldwide. METHODS: The IPDE was administered by 58 psychiatrists and clinical psychologists to 716 patients enrolled in clinical facilities at 14 participating centers in 11 countries in North America, Europe, Africa, and Asia. To determine interrater reliability, 141 of the IPDEs (20%) were independently rated by a silent observer. To determine temporal stability, 243 patients (34%) were reexamined after an average interval of 6 months. RESULTS: The IPDE proved acceptable to clinicians and demonstrated an interrater reliability and temporal stability roughly similar to instruments used to diagnose the psychoses, mood, anxiety, and substance use disorders. CONCLUSION: It is possible to assess personality disorders with reasonably good reliability in different nations, languages, and cultures using a semistructured clinical interview that experienced clinicians find relevant, meaningful, and user-friendly.

Anxiety and depressive disorders and the five-factor model of personality: a higher- and lower-order personality trait investigation in a community sample.

We describe in detail normal personality traits in persons with psychiatrist-ascertained anxiety and depressive disorders in a general population sample. We investigated Revised NEO Personality Inventory traits in 731 community subjects examined by psychiatrists with the Schedules for Clinical Assessment in Neuropsychiatry. All of the lifetime disorders of interest (simple phobia, social phobia, agoraphobia, panic disorder, obsessive-compulsive disorder (OCD), generalized anxiety disorder, major depressive disorder (MDD), and dysthymia) were associated with high neuroticism. Social phobia, agoraphobia, and dysthymia were associated with low extraversion, and OCD was associated with high openness to experience. In addition, lower-order facets of extraversion (E), openness (O), agreeableness (A), and conscientiousness (C) were associated with certain disorders (specifically, low assertiveness (E) and high openness to feelings (O) with MDD, low trust (A) with social phobia and agoraphobia, low self-discipline (C) with several of the disorders, and low competence and achievement striving (C) with social phobia). Neuroticism in particular was related to acuity of disorder. Longitudinal study is necessary to differentiate state versus pathoplastic effects.

Personality traits in treated Wilson's disease determined by means of the Karolinska Scales of Personality (KSP).

OBJECTIVE: The aim was to elucidate the personality traits of patients with treated Wilsons disease (WD) in comparison to healthy volunteers. METHOD: Twenty-five WD patients, ten females and 15 males, with a mean age of 35.2 +/- 8.3 years completed the Karolinska Scales of Personality (KSP), a self-report inventory comprising 15 separate scales. The results were compared to a control series comprising 200 men and 200 women drawn from the general population. RESULTS: The patients with treated WD scored significantly lower than the healthy controls on aggressivity-hostility-related scales and the scale measuring Psychic Anxiety. Patients with predominantly hepatic symptoms had the lowest aggressivity-related scores and patients with predominantly neurological symptoms had the lowest Irritability, Guilt and Detachment scores and the highest Impulsiveness and Muscular Tension scores. Both groups scored low on the Somatic Anxiety scale. CONCLUSION: The present results illustrate that patients with treated WD have significant deviations in personality traits, especially in aggressivity-hostility-related scales and Psychic Anxiety, compared to healthy controls when investigated by means of a self-report inventory, the KSP. The deviations were not related to age, age at onset or duration of the disease.

The Personal Acquaintance Measure: a tool for appraising one's acquaintance with any person.

The authors developed and evaluated the psychometric properties of the 18-item Personal Acquaintance Measure (PAM) and investigated how the PAM relates to self- other agreement in personality ratings. Results support that 6 factors represent the PAM (Duration, Frequency of Interaction, Knowledge of Goals, Physical Intimacy, Self-Disclosure, Social Network Familiarity), which showed evidence of internal consistency, test-retest reliability over 3 weeks, sensitivity to known group differences, discriminant validity from socially desirable responding, and convergent validity with other relationship inventories. Results also show that the PAM positively predicted self-other agreement. The authors discuss the implications of these findings for the PAM and research in person perception, although this measure may also be used in other research areas.

Personality in its natural habitat: manifestations and implicit folk theories of personality in daily life.

To examine the expression of personality in its natural habitat, the authors tracked 96 participants over 2 days using the Electronically Activated Recorder (EAR), which samples snippets of ambient sounds in participants' immediate environments. Participants' Big Five scores were correlated with EAR-derived information on their daily social interactions, locations, activities, moods, and language use; these quotidian manifestations were generally consistent with the trait definitions and (except for Openness) often gender specific. To identify implicit folk theories about daily manifestations of personality, the authors correlated the EAR-derived information with impressions of participants based on their EAR sounds; judges' implicit folk theories were generally accurate (especially for Extraversion) and also partially gender specific. The findings point to the importance of naturalistic observation studies on how personality is expressed and perceived in the natural stream of everyday behavior.

A cognitive-affective system theory of personality: reconceptualizing situations, dispositions, dynamics, and invariance in personality structure.

A theory was proposed to reconcile paradoxical findings on the invariance of personality and the variability of behavior across situations. For this purpose, individuals were assumed to differ in (a) the accessibility of cognitive-affective mediating units (such as encodings, expectancies and beliefs, affects, and goals) and (b) the organization of relationships through which these units interact with each other and with psychological features of situations. The theory accounts for individual differences in predictable patterns of variability across situations (e.g., if A then she X, but if B then she Y), as well as for overall average levels of behavior, as essential expressions or behavioral signatures of the same underlying personality system. Situations, personality dispositions, dynamics, and structure were reconceptualized from this perspective.

Evaluation of DSM-IV personality disorder criteria as assessed by the structured clinical interview for DSM-IV personality disorders.

The primary objective of this research was to investigate the psychometric and diagnostic efficiency properties of DSM-IV personality disorder (PD) criteria as assessed by the Structured Clinical Interview for DSM-IV Personality Disorders (SCID-II). Logistic regression analyses were also employed to identify discriminating and nondiscriminating diagnostic criteria within specific PD categories. Results based on a community sample of 149 psychotropic medication-free persons, 58% of whom had at least one PD as determined from the SCID-II, suggest problems with the assessment and/or conceptualization of some PD categories, most notably obsessive-compulsive PD. For many PD concepts, diagnostic criteria were identified that either detracted from the overall internal consistency and diagnostic efficiency of their associated PD criteria set or failed to uniquely discriminate individuals with specific PDs from those without. Most of these findings cannot be clearly attributed to limitations associated with the method used to assess PD criteria.

Does delivery matter? Users' perceptions of the significance of trust in the delivery of the Personal Advisor Service in the New Deal for Disabled Persons.

PURPOSE: In the context of welfare pluralism where government in the UK has been contracting a number of public services out to a range of private and voluntary sector organisations, the aim of this study is to explore the extent to which decisions to become involved in employment support programmes are affected by the users' perceptions of those delivering the service. METHOD: A qualitative design involving two focus groups of fourteen participants was employed to examine the attitudes and perceptions of participants in the government's New Deal for Disabled Persons. The study sample was purposefully selected from client records of Shaw Trust a national charity for disabled persons, one of the organisations who have been contracted by the government to provide this service. RESULTS: Two distinct but related themes of disillusionment with the government and the importance of trust emerged from the focus groups. Overall, the data suggests that the identity of those delivering the service significantly influences the decision to participate. As Shaw Trust is a voluntary organisation promoting the rights of disabled persons they were deemed to be trustworthy. The users were sceptical about the government's commitment to improving the lives of disabled people and were reluctant to engage with the state. CONCLUSIONS: Making the transition from dependency on disability benefits to paid employment is a quantum leap. For many the decision to put themselves forward for voluntary support schemes is affected by the extent to which they believe they can trust the agency delivering the service. It is imperative that the government listen to the service users who have been involved in these projects and learn from their experiences.
