Personality, attachment and sexuality related to dating relationship outcomes: contrasting three perspectives on personal attribute interaction.

Although people can bring personal attributes to their relationships that affect how satisfying and enduring those relationships are, it is more often personal attribute interaction that directly determines romantic relationship outcomes. In this study, three general perspectives on personal attribute interaction-similarity, complementarity and exchange perspectives-were contrasted empirically in their ability to predict dating relationship outcomes. Based on questionnaires completed by a sample of 44 heterosexual dating couples, feelings of relationship satisfaction were most closely associated with the interaction of socially valuable attributes, generally supporting the exchange perspective. Similarity of personal attributes was also connected with relationship satisfaction; however, this association was in the negative direction. That is, couples with dissimilar personality traits, attachment styles and sexual strategies were significantly more satisfied with their dating relationships. Complementarity of personal attributes had no link to satisfaction, but complementary couples experienced significantly higher ratings of relationship commitment, especially couples with complementary personalities. Discussion focused on the differences between personal attribute connections with romantic satisfaction and commitment and on the limitations of the present study.

A developmental perspective on personality disorders: lessons from research on normal personality development in childhood and adolescence.

Recent work on normal personality development in children and adolescents points to several conclusions that are relevant for understanding personality pathology. First, child temperament and adult personality traits share many features in common. Second, youths' individual differences can be described in terms of the Big Five personality traits observed in adults; an integrative taxonomy of individual differences in childhood and adolescence is articulated in this article. Third, personality is already moderately stable by the preschool years, but considerable personality change occurs well into the adult years. Taken together, these findings suggest that childhood personality functioning can and should be integrated into developmental research and applied work on personality disorders.

Sadistic personality disorder in sex offenders: relationship to antisocial personality disorder and sexual sadism.

To investigate the relationship of sadistic personality disorder (SPD), as defined in the appendix of DSM-III-R, to other personality disorders and to sexual sadism, 70 sex offenders (27 child molesters, 33 rapists, and 10 murderers) were assessed by the International Personality Disorder Examination. In 19 subjects (27.2%) from the total sample, SPD was diagnosed. The highest overlap appeared with borderline personality disorder (31.6%) and antisocial personality disorder (42.1%). However, in four cases SPD was the only personality disorder diagnosed. Factor analysis of the antisocial and sadistic criteria resulted in four major factors--one factor with high loadings on the sadistic criteria and the violent criteria of antisocial personality disorder, two factors with different forms of adult and juvenile aggression, and a fourth factor with high loadings on the antisocial criteria covering exploitative behavior. The results do not support SPD as a discrete disorder. Nevertheless, SPD may be seen as an important subdimension of antisocial personality disorder, distinct from more exploitative forms of antisocial behavior with less violence. Of those patients with SPD, 42.1% also had a DSM-III-R diagnosis of sexual sadism, which may be the most dangerous configuration.

Structure of personality disorders from the perspective of the Revised Neo Personality Inventory domain scales and the Psychopathology-5 Scales.

This study tested the generality and comprehensiveness of the five-factor model of personality as applied to the Personality Adjective Checklist's (Strack, 1987) personality disorder scales. A sample of 258 undergraduates (113 men and 145 women) completed the Personality Adjective Checklist, the Revised NEO Personality Inventory, and the Psychopathology-5 Scales for partial course credit. A combined principal axis analysis with varimax rotation was performed for nonoverlapping scales of the Personality Adjective Checklist, the Revised NEO Personality Inventory domain scales and the Psychopathology-5 scales. The results indicated four factors which were identified as Neuroticism, Extraversion, Disagreebleness, and Conscientiousness. Openness did not emerge as a separate factor. These results supported the comprehensiveness but not the generality of the five-factor model as applied to personality disorders.

Personal agency and personality in adolescence: silent voices and findings.

We discuss the studies reported in this special issue on the basis of a descriptive framework. We conclude that implicit assumptions-silent voices, as we call them-concerning the transactional influence between person and environment, and concerning the primacy of personal agency exist side by side. We find in the studies both a variable-centred and a person-centred approach, and show that the person-centred approach can complement the variable-centred approach in a fruitful manner. On the other hand, both approaches seem to lead to similar results in the studies reported in this special issue. As a rule, the approaches lead to characterization of categories of adolescents, and moreover they can both be seen as exemplifying transactional thinking in the psychology of adolescence. Personal agency and personality are systematically correlated with developmental outcomes, but there are no strong indications that personal agency and personality are important predictors of later developmental outcomes. Such indications are found to a greater extent as regards the influence of parenting and the quality of the parent-adolescent relationship. Finally, there is evidence that peers have their own specific significance in the exploration of developmental options.

Confirmatory factor analysis of DSM-IV criteria for borderline personality disorder: findings from the collaborative longitudinal personality disorders study.

OBJECTIVE: This study tested the factor structure of the DSM-IV criteria for borderline personality disorder by using confirmatory methods for the analysis of covariance structures in a large group from a multisite study. METHOD: A total of 668 primarily treatment-seeking subjects were reliably assessed for personality disorders by using the Diagnostic Interview for DSM-IV Personality Disorders. Associations among criteria for borderline personality disorder were examined. A confirmatory factor analysis was performed to test diagnosis as a unitary construct and to test an earlier-reported three-factor model comprising disturbed relatedness, behavioral dysregulation, and affective dysregulation. The three-factor model was subsequently tested by using a subset (N=498) of the study group that was reassessed 2 years later by independent evaluators who were blind to original diagnoses. RESULTS: Internal consistency of the borderline personality disorder diagnosis was adequate for both baseline and follow-up assessments. A confirmatory factor analysis model testing the borderline personality disorder diagnosis as a unitary construct provided good fit, and the three-factor model offered a significantly better fit for the baseline assessment. The three-factor model was replicated with the 2-year follow-up data. CONCLUSIONS: The diagnostic criteria for borderline personality disorder appear to reflect a statistically coherent construct. Three homogeneous components were supported empirically, lending conceptual clarity to different classes of the criteria for borderline personality disorder.

Factors associated with high use of public mental health services by persons with borderline personality disorder.

OBJECTIVE: The research presented here was a pilot study to identify clinical factors associated with high use (as opposed to lower use) of inpatient psychiatric services by persons with borderline personality disorder. METHODS: The initial sample was a random sample of English- and Spanish-speaking persons aged 18 to 60 years who had received at least one outpatient mental health service in the previous 90-day period and were enrolled in one of the participating mental health centers in King County, Washington. A random sample of persons who met selection criteria was randomly drawn; persons with high levels of use were oversampled to ensure adequate representation. Twenty-nine participants met full criteria for borderline personality disorder on the Personality Disorders Examination structured interview and completed all measures. Fifteen (52 percent) of these had a high level of use of inpatient services, and 14 did not. RESULTS: High use of inpatient psychiatric services was predicted by a history of parasuicide in the previous two years but not by the number or severity of parasuicides; by the presence and number of anxiety disorders but not by depression or psychotic or substance use disorders; and by poorer cognitive functioning. Life stressors, global functioning, and health service variables did not differentiate patients with high levels of service use from other patients with borderline personality disorder. CONCLUSIONS: Further research should explore these predictors of service use to determine whether they are replicated in larger samples, and treatments that target these variables should be evaluated.

Person, personality, self, and identity: a philosophically informed conceptual analysis.

Who is the person, or self, associated with personality disorder and its treatment? How are we to account for a self conceptualized in terms of schemas and representations, that at the same time--as self--scrutinizes these schemas and representations (as in cognitive therapy for personality disorders)? Five approaches to personhood are examined: metaphysical, empirical, transcendental, hermeneutical, and phenomenological. An elementary sense of selfhood is tied to all one's experiences and activities; this sense of self is experientially irreducible and conceptually connected to a primordial form of self-relatedness. After examining these issues, I formulate four provisional conclusions: (a) the separation between person and roles (functions, personality features) is a modern fiction--persons are not neutral bearers of roles and functions; (b) the concept of personality in DSM-IV refers to nonhomogeneous behaviors such as feelings, moods, inclinations, temperaments, and habits, and these behaviors differ with respect to their distance to the core self; (c) there exists an enormous variety of ways of self-relating and this variety may affect the contents of the core self under certain circumstances; and (d) the concept of person may be primitive; that is, irreducible and referring to a background of unity and integrity.

Co-occurrence of personality disorders in persons with kleptomania: a preliminary investigation.

This study was conducted to examine the co-occurrence of personality disorders in a group of persons with kleptomania. Twenty-eight subjects with DSM-IV kleptomania were administered the Structured Clinical Interview for DSM-III-R Personality Disorders and a semistructured interview to assess demographics and clinical characteristics. Twelve subjects with kleptomania (42.9%) met criteria for at least one personality disorder. The most common were: paranoid (n = 5; 17.9%), schizoid (n = 3; 10.7%), and borderline (n = 3; 10.7%). Subjects with kleptomania combined with personality disorders had an earlier age of onset of stealing behavior (13.4 +/- 5.6 years compared with 27.4 +/- 14.2 years in those who had kleptomania only; t = 3.225; df = 26; p = .006). Severity of kleptomania symptoms did not differ among the Axis II comorbidities. Persons with kleptomania appear to have a high prevalence of personality disorders. Further studies are needed to understand the relationship of kleptomania to personality.

Personality assessment based on the five-factor model of personality structure in patients with primary open-angle glaucoma.

PURPOSE: Several characteristic personality types have been reported for glaucoma patients in previous studies. However, none of the previous studies used a common structural theory of personality. In this study, we conducted a multicenter cross-sectional case-control study using the recently established five-factor model of personality structure. METHODS: Personality was evaluated using the Neuroticism Extraversion Openness Five-Factor Inventory (NEO-FFI), which is a questionnaire specifically designed to test the five-factor model of personality: neuroticism (N), extraversion (E), openness (O), agreeableness (A), and conscientiousness (C). Eligible questionnaires were obtained from 196 patients with primary open-angle glaucoma (POAG) (99 men, 97 women) and 223 reference subjects with no ocular disease except cataract (87 men, 136 women). The mean score of each NEO-FFI factor for POAG patients was compared to the scores for the reference subjects. RESULTS: Compared with the reference subjects, the mean N score was significantly higher (P = 0.013), the mean scores for A and C were significantly lower (P = 0.007 and P = 0.001, respectively), and the mean E score tended to be lower (P = 0.055) in male POAG patients. The mean E score was significantly lower (P = 0.023) in female POAG patients. CONCLUSIONS: Characteristic personality traits were noted in POAG patients, and a more significant relationship was found between personality and glaucoma in men than in women.

The relationship between DSM-III personality disorders and the five-factor model of personality.

Two hundred twenty-four first-degree relatives of patients with psychotic disorders were administered the Structured Interview for DSM-III Personality Disorders (SIDP) and completed a self-report instrument to assess dimensions of the five-factor model of personality. All of the DSM-III personality disorders were related to one or more dimensions of the five personality factors; however, the correlations were generally low. It seems that the five personality factors describe important features of DSM-III personality disorders, but are not sufficient to completely explain their characteristics. Future use of the five-factor model in conjunction with personality disorder diagnoses may provide useful information for clinical work and research purposes.

Personality disorders and personality variations in relatives of patients with bipolar affective disorders.

Family studies may elucidate etiological relationships between two psychopathological conditions. This study explored the prevalences of personality disorders (DSM-III-R) and the variation of personality traits measured by the Munich Personality Test (MPT) in first-degree relatives of patients with bipolar disorder in comparison to control families recruited in the general population. Although the overall prevalence of having any personality disorder did not distinguish both groups of relatives we found significantly more compulsive personality disorders among relatives of probands with bipolar disorder. Relatives of patients with bipolar disorder also revealed significantly higher mean scores of "rigidity' (MPT); other personality traits, including neuroticism and extraversion, did not distinguish both groups. The observed differences in personality features between both groups of relatives are not mediated by current or previous axis I disorders. Therefore, they may reflect overlap of etiological factors of familial origin.

The big seven model of personality and its relevance to personality pathology.

Proponents of the Big Seven model of personality have suggested that Positive Valence (PV) and Negative Valence (NV) are independent of the Big Five personality dimensions and may be particularly relevant to personality disorder. These hypotheses were tested with 403 undergraduates who completed a Big Seven measure and markers of the Big Five and personality pathology. Results revealed that PV and NV incrementally predicted personality pathology dimensions beyond those predicted by multiple markers of the Big Five. However, factor analyses suggested that PV and NV might be best understood as specific, maladaptive aspects of positive emotionality and low agreeableness, respectively, as opposed to independent factors of personality. Implications for the description of normal and abnormal personality are discussed.

Clinical study of the relation of borderline personality disorder to Briquet's syndrome (hysteria), somatization disorder, antisocial personality disorder, and substance abuse disorders.

OBJECTIVE: The criteria for borderline personality disorder seem to select patients with very high rates of Briquet's syndrome (hysteria), somatization disorder, antisocial personality disorder, and substance abuse disorders. This study was undertaken to determine whether systematic assessment of patients with borderline personality disorder would reveal characteristic features of that condition which would distinguish it from these other disorders. METHOD: Eighty-seven white female patients (75 in St. Louis and 12 in Milan, Italy) who had borderline personality disorder according to both the DSM-III-R criteria and the Revised Diagnostic Interview for Borderlines were further examined with the DSM-III-R Checklist and the Perley-Guze Hysteria Checklist to determine their patterns of psychiatric comorbidity. RESULTS: Every patient had at least one additional DSM diagnosis. Patients in St. Louis and Milan averaged five and four additional diagnoses, respectively. Eighty-four percent of the patients in St. Louis met criteria for either somatization disorder, Briquet's syndrome, antisocial personality disorder, or substance abuse disorders. Patterns of comorbidity for panic (51%), generalized anxiety disorder (55%), and major depression (87%) in St. Louis were consistent with those in other studies. CONCLUSIONS: The data indicate that the boundaries for the borderline condition are not specific and identify a high percentage of patients with these other disorders. Furthermore, the comorbidity profiles closely resemble the psychiatric profiles of patients with these disorders. If the borderline syndrome is meant to include all of these disorders, its usefulness as a diagnosis is limited. Until the fundamental features of borderline personality disorder that distinguish it from the others are identified, it is recommended that clinicians carefully assess patients for these other diagnoses. Efforts should be made to change the borderline personality disorder criteria by shifting away from overlap with the criteria for the other disorders.

Relationship of family history, antisocial personality disorder and personality traits in young men at risk for alcoholism.

Studies examining possible risk factors for the development of alcoholism have focused recently on a variety of personality factors, including those associated with risk-taking behaviors. Alcohol-seeking behavior leading to the abuse of alcohol may be associated with a variety of risk-taking behaviors that derive from certain personality traits. Further, there is evidence that personality traits are transmitted across generations. This study examined the relationship of a family history of alcoholism, antisocial personality disorder (ASP) and alcohol use to several personality traits including the Tri-dimensional Personality Questionnaire (TPQ) in a sample (N = 91) of nonalcoholic, young male volunteers. The men with ASP scored higher than the non-ASP men on the Novelty Seeking Scale of the TPQ, but not on the Harm Avoidance or Reward Dependence subscales. In addition, ASP men scored higher than non-ASP men on a measure of impulsivity and tended to score higher on measures of sensation seeking, psychopathy and monotony avoidance. A family history of alcoholism did not differentiate the young men on any of the childhood behavior problems, personality measures or alcohol-related variables.

Do homosexual persons use health care services more frequently than heterosexual persons: findings from a Dutch population survey.

Use of health care services has been suggested to be lower among homo- or bisexual persons than among heterosexual persons, due to a lack of trust in the health care system. However, population-based studies on differences in health care utilization according to sexual orientation are scarce. The purpose of the current study was to explore differences in health care utilization and confidence in health care between heterosexual, bisexual and homosexual persons. A survey of a random sample of patients of Dutch general practices (n = 9684) gathered data on socio-demographic variables, sexual orientation, health status, confidence in health care and health care utilization. Differences in health care utilization between homo- or bisexual persons and heterosexual persons were analyzed with logistic regression analysis, in which we statistically adjusted for socio-demographics and health status. Reported health was lower among homosexual men and women as compared to heterosexual persons. There were no sexual orientation-related differences in confidence in health care. Controlling for health status, it appeared that gay men more frequently used mental and somatic health care than heterosexual men, and that lesbian or bisexual women more frequently used mental health care than heterosexual women. We found a higher rate of health care use among homosexual and bisexual persons as compared to heterosexual persons, that could only be partly explained by differences in health status. To gain a better understanding of our findings, data on the predisposition to use health services among homosexual and bisexual men and women is needed.

Use of personal-indoor-outdoor sulfur concentrations to estimate the infiltration factor and outdoor exposure factor for individual homes and persons.

A study of personal, indoor, and outdoor exposure to PM2.5 and associated elements has been carried out for 37 residents of the Research Triangle Park area in North Carolina. Participants were selected from persons expected to be at elevated risk from exposure to particles, and included 29 persons with hypertension and 8 cardiac patients with implanted defibrillators. Participants were monitored for 7 consecutive days in each of four seasons. One goal of the study was to estimate the contribution of outdoor PM2.5 to indoor concentrations. This depends on the infiltration factor Finf, the fraction of outdoor PM2.5 remaining airborne after penetrating indoors. After confirming with our measurements the findings of previous studies that sulfur has few indoor sources, we estimated an average Finf for each house based on indoor/outdoor sulfur ratios. These estimates ranged from 0.26 to 0.87, with a median value of 0.55. Since these estimates apply only to particles of size similar to that of sulfur particles (0.06-0.5 microm diameter), and since larger particles (0.5-2.5 microm) have lower penetration rates and higher deposition rates, these estimates are likely to be higher than the true infiltration factors for PM2.5 as a whole. In summer when air conditioners were in use, the sulfur-based infiltration factor was at its lowest (averaging 0.50) for most homes, whereas the average Finf for the other three seasons was 0.62-0.63. Using the daily estimated infiltration factor for each house, we calculated the contribution of outdoor PM2.5 to indoor air concentrations. The indoor-generated contributions to indoor PM2.5 had a wider range (0-33 microg/m3) than the outdoor contributions (5-22 microg/m3). However, outdoor contributions exceeded the indoor-generated contributions in 27 of 36 homes. A second goal of the study was to determine the contribution of outdoor particles to personal exposure. This is determined by the "outdoor exposure factor" Fpex, the fraction of outdoor PM2.5 contributing to personal exposure. As with Finf, we estimated Fpex by the personal/outdoor sulfur ratios. The estimates ranged from 0.33 to 0.77 with a median value of 0.53. Outdoor air particles were less important for personal exposures than for indoor concentrations, with the median outdoor contribution to personal exposure just 49%. We regressed the outdoor contributions to personal exposures on measured outdoor PM2.5 at the central site. The regressions had R2 values ranging from 0.19 to 0.88 (median = 0.73). These values provide an indication of the extent of misclassification error in epidemiological estimates of the effect of outdoor particles on health.

Global, local, and graphical person-fit analysis using person-response functions.

Person-fit statistics test whether the likelihood of a respondent's complete vector of item scores on a test is low given the hypothesized item response theory model. This binary information may be insufficient for diagnosing the cause of a misfitting item-score vector. The authors propose a comprehensive methodology for person-fit analysis in the context of nonparametric item response theory. The methodology (a) includes H. Van der Flier's (1982) global person-fit statistic U3 to make the binary decision about fit or misfit of a person's item-score vector, (b) uses kernel smoothing (J. O. Ramsay, 1991) to estimate the person-response function for the misfitting item-score vectors, and (c) evaluates unexpected trends in the person-response function using a new local person-fit statistic (W. H. M. Emons, 2003). An empirical data example shows how to use the methodology for practical person-fit analysis.
