Severity Indices of Personality Problems (SIPP-118) in adolescents: reliability and validity

The Severity Indices of Personality Problems (SIPP-118; Verheul et al., 2008) is a self-report questionnaire focusing on core components of (mal)adaptive personality functioning. The SIPP-118 was developed and validated in an adult population. In adult populations, the 16 facets of the SIPP-118 fit into 5 higher order domains: self-control, identity integration, relational capacities, social concordance, and responsibility. In this study we present the 1st psychometric properties of the SIPP-118 in adolescents. We compared the SIPP-118 scores of a patient and a nonpatient sample of adolescents, and compared personality disordered and non-personality disordered adolescents. In addition, the relationship between scores on the SIPP-118 and other clinical instruments (Symptom Checklist-90-Revised; SCL-90-R; Derogatis, 1975; Dimensional Assessment of Personality Pathology-Basic Personality; DAPP-BQ; Livesley & Jackson, 2002) was investigated. The questionnaires were completed by 378 adolescent patients and 389 adolescents in the community. Facets appeared to be homogeneous, as alpha coefficients ranged from .62 to .89, indicating moderate to acceptable reliability. Also, more pathological SIPP-118 scores were found in the patient sample, and more specifically in the personality disordered sample, suggesting that the facet scores of the SIPP-118 can discriminate between various populations (divergent validity). Correlation with other clinical instruments was moderate to high (-.82 to .10). Taken together, the SIPP-118 seems to be a promising instrument measuring personality pathology in adolescents.     

Criterion-related validity of the three-factor model of psychopathy: personality, behavior, and adaptive functioning

The Psychopathy Checklist-Revised (PCL-R) has been conceptualized as indexing two distinct but correlated factors. Previous research has established that these factors demonstrate distinct patterns of relations with external criteria. However, more recent findings suggest that the PCL-R psychopathy construct may encompass three distinguishable factors, reflecting affective, interpersonal, and behavioral symptoms. Here, we evaluated the validity of this newer three-factor model of the PCL-R factors with reference to external criteria from the domains of personality, antisocial behavior; and adaptive functioning in a sample of 310 incarcerated offenders. The interpersonal factor was related to social dominance, low stress reactivity, and higher adaptive functioning; the affective factor was correlated with low social closeness and violent offending; and the behavioral factor was associated with negative emotionality, disinhibition, reactive aggression, and poor adaptive functioning. These findings provide support for the convergent and discriminant validity of these psychopathy facets.     

The psychometric properties of the Portuguese version of the Personality Inventory for DSM‐5

The DSM‐5 Section III proposes a hybrid dimensional‐categorical model of conceptualizing personality and its disorders that includes assessment of impairments in personality functioning (criterion A) and maladaptive personality traits (criterion B). The Personality Inventory for the DSM‐5 is a new dimensional tool, composed of 220 items organized into 25 facets that delineate five higher order domains of clinically relevant personality differences, and was developed to operationalize the DSM‐5 model of pathological personality traits. The current studies address the internal consistency (study 1), the test‐retest reliability (study 2) and the criterion validity (studies 3 and 4) of the Portuguese version of the PID‐5 in samples of native speaking psychology students. Results indicated good internal consistency reliabilities and good temporal stability reliabilities for the majority of the PID‐5 traits. The correlational pattern of the PID‐5 traits with two measures of personality was in accordance with theoretical expectations and showed its concurrent validity.     

Validation of Self-Report Impairment Measures for Section III Obsessive–Compulsive and Avoidant Personality Disorders

This study examined the validity of newly developed disorder-specific impairment scales (IS), modeled on the Level of Personality Functioning Scale, for obsessive–compulsive (OCPD) and avoidant (AvPD) personality disorders. The IS focused on content validity (items directly reflected the disorder-specific impairments listed in DSM-5 Section III) and severity of impairment. A community sample of 313 adults completed personality inventories indexing the DSM-5 Sections II and III diagnostic criteria for OCPD and AvPD, as well as measures of impairment in the domains of self- and interpersonal functioning. Results indicated that both impairment measures (for AvPD in particular) showed promise in their ability to measure disorder-specific impairment, demonstrating convergent validity with their respective Section II counterparts and discriminant validity with their noncorresponding Section II disorder and with each other. The pattern of relationships between scores on the IS and scores on external measures of personality functioning, however, did not indicate that it is useful to maintain a distinction between impairment in the self- and interpersonal domains, at least for AvPD and OCPD.     

Experimental manipulation of NEO-PI-R items.

Research assessing the relationship of the Five-factor model (FFM) of personality to personality disorder symptomatology has generally been consistent with theoretical expectations. Three exceptions, however, have been failures to confirm predicted associations of the NEO-Personality Inventory-Revised (NEO-PI-R) Conscientiousness scale with obsessive-compulsive personality disorder symptomatology, the NEO-PI-R Agreeableness scale with dependent symptomatology, and the NEO-PI-R Openness scale with schizotypal symptomatology. It was the hypothesis of this study that these findings might be due in part to a relative emphasis on adaptive rather than maladaptive variants of these domains of personality functioning within the NEO-PI-R. This hypothesis was tested by experimentally altering NEO-PI-R items to reverse their implications for maladaptiveness. The predicted correlations of the FFM were confirmed with the experimentally altered items in a sample of 86 adult psychiatric outpatients.     

Construct, concurrent and discriminant validity of Type D personality in the general population: associations with anxiety, depression, stress and cardiac output

The Type D personality, identified by high negative affectivity paired with high social inhibition, has been associated with a number of health-related outcomes in (mainly) cardiac populations. However, despite its prevalence in the health-related literature, how this personality construct fits within existing personality theory has not been directly tested. Using a sample of 134 healthy university students, this study examined the Type D personality in terms of two well-established personality traits; introversion and neuroticism. Construct, concurrent and discriminant validity of this personality type was established through examination of the associations between the Type D personality and psychometrically assessed anxiety, depression and stress, as well as measurement of resting cardiovascular function. Results showed that while the Type D personality was easily represented using alternative measures of both introversion and neuroticism, associations with anxiety, depression and stress were mainly accounted for by neuroticism. Conversely, however, associations with resting cardiac output were attributable to the negative affectivity-social inhibition synergy, explicit within the Type D construct. Consequently, both the construct and concurrent validity of this personality type were confirmed, with discriminant validity evident on examination of physiological indices of well-being.     

Establishing construct validity for Openness-to-Experience in middle childhood: Contributions from personality and temperament

Controversy exists over the validity of child Openness-to-Experience (OE). To establish construct validity for child OE, data were collected for 346 children (51% girls) aged 9-to-10-years (M = 9.92, SD = 0.83). Parents completed questionnaires about their children’s personality, temperament, and behavioral problems and competencies. Factor analyses of relevant personality and temperament facets revealed a robust OE factor made up of three facets: Intellect, Imagination, and Sensitivity. Evidence for convergent and discriminant validity was established via associations with other personality traits, and behavioral problems and competencies. Results underscore the importance of drawing from both temperament and personality literatures in attempts to establish construct validity for child trait domains as well as examining facet-level associations between OE and child behavior.     

Evolution, the Five-Factor Model, and Levels of Personality

ABSTRACT This article interprets the five-factor model as subsuming variation in normative, species-typical systems with adaptive functions in the human environment of evolutionary adaptedness. It is argued that the evolutionary logic of personality systems is apparent in the patterning of mean sex differences in personality. Personality systems are conceptualized as evolved motivational systems with an affective core. The evolved motive dispositions at the core of personality anchor a hierarchy of levels of cognitive and behavioral functioning aimed at attaining or avoiding the affective states central to these personality systems. Personality systems are seen as often in dynamic conflict within individuals and as highly compartmentalized in their functioning between settings. While variation in personality consists of a range of viable strategies for humans, extremes on these systems tend to be maladaptive, although in at least some cases individuals who approach the maladaptive extremes of individual variation may be viewed as engaging in high-risk evolutionary strategies. Within this wide range of viable strategies, personality variation functions as a resource environment for individuals in the sense that personality variation is evaluated according to the interests of the evaluator.     

Experimental Manipulation of NEO-PI-R Items

Research assessing the relationship of the Five-factor model (FFM) of personality to personality disorder symptomatology has generally been consistent with theoretical expectations. Three exceptions, however, have been failures to confirm predicted associations of the NEO-Personality Inventory-Revised (NEO-PI-R; Costa & McCrae, 1992b) Conscientiousness scale with obsessive-compulsive personality disorder symptomatology, the NEO-PI-R Agreeableness scale with dependent symptomatology, and the NEO-PI-R Openness scale with schizotypal symptomatology. It was the hypothesis of this study that these findings might be due in part to a relative emphasis on adaptive rather than maladaptive variants of these domains of personality functioning within the NEO-PI-R. This hypothesis was tested by experimentally altering NEO-PI-R items to reverse their implications for maladaptiveness. The predicted correlations of the FFM were confirmed with the experimentally altered items in a sample of 86 adult psychiatric outpatients.     

The Three Domains of Disgust Scale: factor structure, psychometric properties, and conceptual limitations

This investigation examined the measurement properties of the Three Domains of Disgust Scale (TDDS). Principal components analysis in Study 1 (n = 206) revealed three factors of Pathogen, Sexual, and Moral Disgust that demonstrated excellent reliability, including test-retest over 12 weeks. Confirmatory factor analyses in Study 2 (n = 406) supported the three factors. Supportive evidence for the validity of the Pathogen and Sexual Disgust subscales was found in Study 1 and Study 2 with strong associations with disgust/contamination and weak associations with negative affect. However, the validity of the Moral Disgust subscale was limited. Study 3 (n = 200) showed that the TDDS subscales differentially related to personality traits. Study 4 (n = 47) provided evidence for the validity of the TDDS subscales in relation to multiple indices of disgust/contamination aversion in a select sample. Study 5 (n = 70) further highlighted limitations of the Moral Disgust subscale given the lack of a theoretically consistent association with moral attitudes. Lastly, Study 6 (n = 178) showed that responses on the Moral Disgust scale were more intense when anger was the response option compared with when disgust was the response option. The implications of these findings for the assessment of disgust are discussed.     

An evaluation of evaluative personality terms: a comparison of the big seven and five-factor model in predicting psychopathology

Two personality models are compared regarding their relationship with personality disorder (PD) symptom counts and with lifetime Axis I diagnoses. These models share 5 similar domains, and the Big 7 model also includes 2 domains assessing self-evaluation: positive and negative valence. The Big 7 model accounted for more variance in PDs than the 5-factor model, primarily because of the association of negative valence with most PDs. Although low-positive valence was associated with most Axis I diagnoses, the 5-factor model generally accounted for more variance in Axis I diagnoses than the Big 7 model. Some predicted associations between self-evaluation and psychopathology were not found, and unanticipated associations emerged. These findings are discussed regarding the utility of evaluative terms in clinical assessment.     

The Big Five Personality Traits and the Life Course: A 45-Year Longitudinal Study

One hundred sixty-three men who have been followed prospectively for over 45 years were rated on a set of 25 personality traits at the end of their college careers and took the NEO-PI at approximately ages 67–68. The college traits were transformed, via a rating procedure, to scales assessing each of the Big Five dimensions and related to the NEO-PI. Three traits—Neuroticism, Extraversion, and Openness—exhibited significant correlations across the 45-year interval. Furthermore, the trait profiles remained relatively stable over that interval. Both sets of personality traits were related to a wide variety of life course variables representing the domains of global adult adjustment, career functioning/success, creativity, social relations, mental health, substance abuse, childhood characteristics, familial history of pathology, maturity of defenses, and political attitudes. Conscientiousness in college was the best predictor of what happened to the men in the future, whereas Neuroticism in late midlife was the best correlate of life course functioning across a variety of domains.     

Assessing Level of Personality Organization With the Psychodiagnostic Chart: A Validity Study

Heterogeneity within diagnostic types and comorbidity across diagnostic groups render a specific personality disorder anything but specific, leading researchers and clinicians to increasingly focus on the general severity of personality pathology. Personality pathology severity is reflected in one's level of personality organization (LPO) and research has demonstrated that LPO is a significant predictor of treatment response. This investigation examined the reliability and validity of the Psychodiagnostic Chart (PDC) in assessing the LPO dimension of the Psychodynamic Diagnostic Manual (PDM; PDM Task Force, 2006). Among a sample of 88 urban-dwelling women seeking primary medical care, the LPO dimension of the PDC received fair to good interrater reliability among 6 psychodynamic psychologists. Convergent validity was demonstrated with contrast analysis and individual correlations that yielded statistically significant associations between LPO scores and conceptually related psychodynamic variables (e.g., defensive functioning, object relations) and self-reported personality pathology scores. Support for discriminant validity was limited by the modest power associated with the sample size. Exploratory analyses examining LPO scores and measures of physical health and intimate partner violence were conducted. Our results supported the reliability, validity, and practical use of the LPO dimension of the PDC.     

The construction and initial validation of the Work Volition Scale

This study constructed an instrument measuring work volition for adult populations, defined as the perceived capacity to make occupational choices despite constraints. In Study 1, an exploratory factor analysis produced a 3-factor structure containing subscales assessing general volition, financial constraints, and structural constraints. The full Work Volition Scale (WVS) and three subscales demonstrated adequate to strong internal consistency. In Study 2, a confirmatory factor analysis replicated the factor structure from Study 1 with a new sample. The hypothesized factor structure of the WVS was a good fit to the data and was internally consistent. In Studies 2 and 3, work volition correlated in hypothesized directions with work locus of control, core self-evaluations, career barriers, career compromise, and adaptive personality traits, providing evidence of construct validity. Additionally, none of these correlations was large enough to indicate overlapping constructs. Finally, work volition added unique variance in the prediction of job satisfaction above and beyond the variance accounted for by work locus of control, core self-evaluations, and the big 5 personality traits, suggesting incremental validity of the construct. Research implications are discussed.     

Computerized adaptive personality testing: a review and illustration with the MMPI-2 Computerized Adaptive Version

Computerized adaptive testing in personality assessment can improve efficiency by significantly reducing the number of items administered to answer an assessment question. Two approaches have been explored for adaptive testing in computerized personality assessment: item response theory and the countdown method. In this article, the authors review the literature on each and report the results of an investigation designed to explore the utility, in terms of item and time savings, and validity, in terms of correlations with external criterion measures, of an expanded countdown method-based research version of the Minnesota Multiphasic Personality Inventory-2 (MMPI-2), the MMPI-2 Computerized Adaptive Version (MMPI-2-CA). Participants were 433 undergraduate college students (170 men and 263 women). Results indicated considerable item savings and corresponding time savings for the adaptive testing modalities compared with a conventional computerized MMPI-2 administration. Furthermore, computerized adaptive administration yielded comparable results to computerized conventional administration of the MMPI-2 in terms of both test scores and their validity. Future directions for computerized adaptive personality testing are discussed.
