Reliability of personality disorder symptoms and personality traits in substance-dependent inpatients

The authors compared the internal consistency, 1-year temporal stability, and self-informant agreement of ratings of personality trait (NEO Five-Factor Inventory; NEO-FFI; P. T. Costa & R. R. McCrae, 1992) and personality disorder symptom severity (Structured Clinical Interview for DSM-III-R Personality Disorders Questionnaire; SCID-II-Q; R. L. Spitzer, J. B. W. Williams, M. Gibbon, & M. First, 1990) in 131 substance-dependent inpatients. Internal consistency coefficients were acceptable to very good for most NEO-FFI and SCID-II-Q scales, and temporal stability correlations were significant for all measures. Agreement between patient and informant ratings was more modest. Substance abuse and depression symptom severity moderated the temporal stability and self-informant agreement of several personality trait and disorder ratings. The authors did not find that the five factors were more reliable than the Axis II symptoms. Issues related to the reliability of personality assessment in multiply diagnosed patients are discussed.     

A scale for measuring students' anti-intellectualism.

Two studies were conducted which report the development and testing of the Student Anti-Intellectualism Scale, designed as a measure of anti-intellectual attitudes in students enrolled in higher education. The first study analyzed an initial 25-item scale to assess internal consistency and factorial structure. The second study examining a final version of the scale was conducted to test reliability and factorial structure, in addition to assessing evidence of construct validity. The second study also assessed temporal stability and social desirability response set. The studies indicated the scale had a fundamentally unidimensional structure and considerable internal consistency and also provided support for the validity of the anti-intellectualism constrict. Anti-intellectualism is discussed in the context of personality theory, and suggestions are offered with reference to establishing anti-intellectualism as a trait relative to the five-factor model of personality.     

The hierarchy of consistency: A review and model of longitudinal findings on adult individual differences in intelligence,personality and self-opinion

When viewed in the aggregate, studies of the longitudinal consistency of intelligence, personality traits and self-opinion (self-esteem, life satisfaction etc.) show a hierarchy of consistency. Uncorrected retest coefficients over periods of 6 months to 50 yr are analyzed as the product of period-free reliability (R) and the true stability of the construct (sⁿ, where s is the coefficient of annual stability and n the number of years of the retest interval). The annual stabilities of intelligence, personality traits and self-opinions are estimated as 0.99, 0.98 and 0.94, respectively. While intelligence and personality may be regarded as relatively stable characteristics over the length of the adult lifespan, self-opinion has little stability over periods of more than 10 yr. The hierarchy of consistency should be taken into account in causal models of human development. Although self-opinion is not a longitudinally-stable characteristics, it may still be predicted over long periods of time by higher-order constructs such as personality traits and intelligence.     

Intraperson Consistency in Financial Risk Tolerance Assessment: Temporal Stability,Relationship to Total Score,and Effect on Criterion-related Validity

Purpose  

In assessing financial risk tolerance it is common practice to compute an overall score but not the intraperson variability across test items (because the latter is believed to be just error variance). We analyzed (1) the stability of intraperson variability, (2) its correlation to the total score, (3) its moderating effect on validity coefficients, and (4) its relation to internal consistency reliability and test–retest reliability.     

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.     

The Self-Perception Profile for Children: further evidence for its factor structure, reliability, and validity

This article presents further evidence for the psychometric qualities of the Self-Perception Profile for Children (SPPC), a widely used questionnaire for assessing self-esteem in youths. The SPPC was administered to a large sample of Dutch school children (N=1143) in order to study its factor structure, reliability (internal consistency and test–retest stability), and validity. Results showed that the hypothesized factor structure of the SPPC representing five specific domains of self-esteem (i.e. scholastic competence, social acceptance, athletic competence, physical appearance, and behavioral conduct) provided a reasonable fit for the data. Furthermore, the reliability of the scale appeared to be satisfactory with good internal consistency and test–retest stability. Finally, evidence was also obtained for the validity of the SPPC. More specifically, the scale correlated in a theoretically meaningful way with child-, parent-, and teacher-reports of psychopathology and personality. Altogether, the current findings confirm the notion that the SPPC is a reliable and valid self-report measure for assessing children's self-esteem.     

Prevalence of Type D personality and factorial and temporal stability of the DS14 after myocardial infarction in a Swedish population

This study examined the prevalence of Type D personality and the temporal stability, internal consistency, and construct validity of the DS14 at three time points after myocardial infarction. The prevalence was 14.0% during hospitalization, 25.1% at 1 month, and 19.2% at 12 months. A total of 6.1% of the patients were classified as Type D personality at all three assessments, whereas 68.4% were stable non‐Type D and 25.6% changed between personality classifications. The DS14 had stable structural validity, but low temporal stability over time, especially from hospitalization to the 1‐month and 12‐month follow‐ups (κ = 0.365 and 0.397, respectively).     

A review and analysis of research on the test–retest reliability of professional judgment

This paper analyzes existing research on the test–retest reliability of human judgment, i.e. the extent to which a judge makes identical judgments when presented with identical stimuli on two occasions. Only research involving professional judges who make experimental judgments in a reasonable analog of their everyday experience is included. Studies of both internal consistency reliability and temporal stability reliability are analyzed (where the former refers to the inclusion of repeat stimuli in the same experimental session, and the latter refers to the repeating of the experimental task from a few days to several months later). It is found that (1) the test–retest reliability literature is concentrated in four substantive judgment areas (medicine/psychology, meteorology, human resources management, and business), (2) the literature is extremely variable in terms of research approach/design, the determinants or correlates of test–retest reliability that have been studied, and the quality of the execution and analysis, and (3) mean test–retest reliability differs across both substantive judgment areas and the internal consistency versus temporal stability distinction. An inescapable conclusion from the analysis is that our knowledge of this fundamental property of human judgment is quite meager. Therefore, the paper concludes with suggestions about future research that would address test–retest reliability more systematically. Copyright © 2000 John Wiley & Sons, Ltd.     

Appreciation of Beauty and Excellence: Relationship with Personality,Prosociality and Well-Being

Appreciation of beauty and excellence (ABE) is one of the least studied character strengths. Therefore, this study aims at advancing the knowledge in this area by (1) developing a scale that measures the three categories of appreciation (i.e., beauty, moral excellence, and non-moral excellence), (2) assessing many of its psychometric properties, and (3) examining the relationship of ABE with personality, prosociality, and well-being. In Study 1, we create and assess an initial set of items measuring ABE. In Study 2, we examine the dimensionality of ABE, and test the internal consistency and validity of the scale. Moreover, we assess the relationships between ABE and personality, prosociality and well-being. In Study 3, we test the temporal stability of the scale. Results revealed that a three-dimensional model of ABE showed the best fit to the data. The scale showed good validity (construct, factorial, incremental) and reliability (internal and temporal). Finally, ABE yielded positive associations with prosociality and well-being, and demonstrated to be more than a linear combination of the Big Five factors of personality.     

French adaptation of the Mini-IPIP: A short measure of the Big Five

IntroductionThe Big Five, or the Five-Factor Model (FFM) of personality, is the dominant model in trait psychology. Instruments to assess personality traits are usually long and not available in French. The Mini-International Personality Item Pool (Mini-IPIP) is a brief measure evaluating personality traits according to the Big Five model with promising psychometric properties.ObjectiveThe main purposes of this study were to develop and validate a French adaptation of the Mini-International Personality Item Pool.MethodIn Study 1, adaptation procedures that led to the translation of the French version as well as steps to maximize equivalence are described, in addition to internal consistency, temporal stability, and factor structure within a sample of 139 participants. In study 2, confirmatory factor analysis was carried out with a sample of 1308 participants, and convergent validity was explored with several pertinent constructs.ResultsInternal consistency and test-retest correlations over a four-week period suggest adequate reliability, with coefficients respectively ranging from .64 to .81 and .74 to .89. Exploratory factor analysis suggested a sharply delineated structure. In Study 2, confirmatory factor analyzes revealed a five-factor solution consistent with the Big Five model, and convergent validity with several constructs was detailed.ConclusionOverall, results pointed to a satisfactory equivalence between the original and the adapted instrument. The satisfactory indices of reliability and validity of the Mini-IPIP warrant the use of the French adaptation of the Mini-IPIP.     

Depressive personality: reliability, validity, and relation to dysthymia

The reliability and validity of Schneider's (1958) construct of depressive personality was evaluated in a sample of 177 outpatients, who were administered structured diagnostic and family history interviews, an extensive battery of inventories, and a 6-month follow-up assessment. The criteria for depressive personality had moderate to good interrater reliability, internal consistency, and test-retest stability, and the assessment of depressive personality traits was not influenced by patients' clinical states. In addition, preliminary support for the convergent and discriminant validity of the depressive personality construct was obtained. Although there were significant relations between the depressive personality and Diagnostic and Statistical Manual of Mental Disorders (3rd ed. and rev. 3rd ed.; American Psychiatric Association, 1980, 1987) diagnoses of dysthymia, the depressive personality was not entirely subsumed by existing mood disorders.

Uncovering personality structure with the Inventory of Personality Organization: An exploration of factor structure with a Portuguese sample

IntroductionThe Inventory of Personality Organization (IPO) is a self-report measure intended to assess the severity of personality disturbance according to Otto F. Kernberg's model.ObjectiveTo study factor structure and psychometric properties of the Portuguese version of IPO (IPO-Pt).MethodTwo independent samples of 586 individuals each were used for exploratory and confirmatory factor analyses. Different models were compared in terms of reliability and validity.ResultsA three-factor solution resulted, comprising dimensions labeled as Instability of Self, Instability of Others, and Psychosis. Internal consistency and temporal stability yielded acceptable to excellent results. Correlations with measures of self-concept coherence, emotion dysregulation, psychoticism, symptom severity, and personality disturbance were as expected, and sensitivity to clinical status was confirmed.ConclusionIPO-Pt shows encouraging psychometric qualities and its latent structure resonates with important aspects of Kernberg's model, previous findings, and the DSM-5 level of personality functioning scale.

The stability of adult personality varies across age: Evidence from a two-year longitudinal sample of adult New Zealanders

We model developmental patterns in the stability of Big-Six personality markers over a two-year period in a multi-cohort panel study of adult New Zealanders (n = 3910). Structural Equation Models testing patterns of linear, quadratic and cubic effects identified considerable variation in the stability of most aspects of personality across the adult age range (20–80 years). Agreeableness showed a slight linear decrease in consistency with increasing age. Extraversion, Conscientiousness, Neuroticism, Openness to Experience, and Honesty–Humility exhibited quadratic ‘inverted U’ patterns of rank-order stability. Unlike Agreeableness, the two-year consistency of these other personality dimensions increased from young adulthood towards middle age, then decreased as people progressed toward old age. Implications for personality research and emerging trends are discussed.     

Battered Woman Syndrome Questionnaire (BWSQ) Subscales: Development,Reliability, and Validity

ABSTRACT

The current study describes the development and evaluation of the reliability and validity of four components of a comprehensive assessment designed for the purpose of identifying women who manifest symptoms due to an intimate partner violence (IPV) relationship: The Battered Woman Syndrome Questionnaire (BWSQ). More specifically, the purpose of this study was to evaluate the factor structure, validity, temporal stability and internal consistency of four instruments for measuring current functioning of IPV survivors; (a) Interpersonal relationship (BWSQ-IR), (b) Sexual Dysfunction (BWSQ-SD), (c) Body Image (BWSQ-BI), and (d) Post-Traumatic Stress Checklist (BWSQ-PTSC). Overall, results indicate the BWSQ subscales have good temporal stability and internal consistency. Exploratory factor analysis of the four subscales indicate that each has a unidimensional factor structure. Internal consistency was high for each of the subscales. A two-way mixed effects model, intraclass correlation was used to demonstrate a high degree of test-retest reliability. Convergent and discriminant validity was demonstrated by comparing each subscale with the Revised Adult Attachment Scale (AAS), the Derogatis Interview of Sexual Functioning – Sexual Response (DISF-SR), the Objectified Body Consciousness Scale (OBCS) and the Trauma Symptom Inventory (TSI). The four instruments demonstrate sound psychometric properties as standalone measures as well as subscales of the BWSQ.     

A Serbian Version of Modified and Revised Experiences in Close Relationships Scale (SM–ECR–R)

We present details about the validation of the Serbian version of the Experiences in Close Relationships–Revised questionnaire modified to measure attachment in close relationships in general (SM–ECR–R). Its psychometric features were examined with 2 samples of students (N = 719 and N = 91) and 1 group of employed adults (N = 259). The results obtained in the student sample were equivalent to those obtained in validation studies worldwide, whereas in the more heterogeneous sample of employed adults, internal consistency of both avoidance and anxiety was lower and their intercorrelation was higher. Test–retest reliability was satisfactory, and relations with measures of attachment, empathy, and personality structure were meaningful. The results support the SM–ECR–R as a reliable and valid research instrument, but its internal structure and consistency might vary in different samples, depending on age, education, gender, and culture.
