The Roots of Psychology (Book)

Individual scale characteristics and the inventory structure of the Personality Assessment Inventory (PAI; Morey, 1991) were examined by conducting internal consistency and factor analyses of item and scale score data from a large group (N = 301) of alcohol-dependent patients. Alpha coefficients, mean interitem correlations, and corrected item-total scale correlations for the sample paralleled values reported by Morey for a large clinical sample. Minor differences in the scale factor structure of the inventory from Morey's clinical sample were found. Overall, the findings support the use of the PAI in the assessment of personality and psychopathology of alcohol-dependent patients.     

Psychometric Properties and Norms for the Personality Assessment Inventory in Egg Donors and Gestational Carriers

Although psychological evaluations are an integral element of screening for third-party reproduction and the Personality Assessment Inventory (PAI) is commonly used for these evaluations, little is known about the psychometric properties or normative scores on the PAI among egg donors and carriers. We evaluated the PAI among 1,044 egg donors and gestational carriers from various fertility clinics across the United States. PAI scales were generally internally consistent in this population, although range restriction appeared to attenuate reliability on several scales. The PAI profiles of egg donors and carriers had elevated positive impression management and suppressed clinical scale scores relative to the community standardization sample, as would be expected given the contingencies of this assessment context. Scores were similar across egg donors and carriers and were similar whether the carrier or donor was known or not known to the prospective parents. Sample-specific norms are provided for the use of the PAI in this setting.     

Emergent Issues in Assessing Personality Pathology: Illustrations from Two Studies of Adolescent Personality and Related Pathology

As illustrated by two articles that each investigate personality pathology and its correlates in adolescents—Aelterman et al. (2010) on obsessive-compulsive personality disorder (OCPD) from a dimensional personality perspective, and Barry and Wallace (2010) on indicators of pathological and normative development of youth narcissism—this commentary discusses four important assessment issues that have become more salient as the field considers a shift, through proposed changes in the DSM, to an approach that incorporates trait dimensions as an important aspect of diagnosis: (1) the importance of using multiple information sources for valid personality/ PD assessment; (2) relations of personality traits to (mal)adaptivity in general and also with regard to (3) trait uni- versus bi-polarity; and (4) whether personality types have incremental predictive value beyond their component personality traits and related pathology. The article also discusses why research on childhood and adolescent personality/ PD is important in addressing these issues.     

Comparing Idiothetic, Ipsative, and Normative Indices of Consistency

ABSTRACT Lamiell's (1981) “idiothetic” index has been praised for raising significant conceptual and methodological issues, but Paunonen and Jackson (1986a) indicated that it might not provide any unique information The current study demonstrates that the unique value of the idiothetic index relative to the ipsative, normative, and normative-ipsative indices is dependent in part upon what information is collected and how it is analyzed Subjects completed inventories on three occasions that assessed seven dispositional variables Interindividual analyses indicated a high correlation between the idiothetic method and two of the other models, whereas intra-individual analyses indicated a much lower degree of correlation Intra-individual analyses indicated that the idiothetic method produced higher temporal stability coefficients The idiothetic index provides information not contained in a normative index and it may be more useful to personality researchers for the assessment of temporal stability and for the assessment of traits with extreme base rates     

Fear of Hypoglycemia in Parents of Young Children with Type 1 Diabetes Mellitus

The current study examined fear of hypoglycemia in 81 mothers and 64 fathers of young children with type 1 diabetes (T1DM) using the Hypoglycemia Fear Survey-Parents of Young Children (HFS-P-YC possible range = 26–130). Mothers and fathers completed the HFS-P-YC at enrollment and mothers completed it 2 weeks later. Families recorded daily blood glucose on a standardized meter for 2 weeks. Mothers’ mean total HFS-P-YC score was 75.0 (SD = 17.2) and fathers’ mean score was 66.5 (SD = 18.0). Mothers reported greater HFS-P-YC total and behavior subscale scores than fathers. Mothers’ HFS-P-YC scores were comparable to published HFS scores for mothers of preadolescents with T1DM and higher than adult patients with T1DM. The HFS-P-YC had good internal consistency and test–retest reliability in this sample. These findings suggest parents of young children with T1DM report a high level of fear of hypoglycemia. Additionally, the HFS-P-YC appears to be a reliable measure in this population.     

Use of structured self-report assessment to diagnose borderline personality disorder during major depressive episodes

Diagnosis of borderline personality disorder (BPD) during episodes of major depression (MDE), although clinically important, is complicated in several respects when using self-report methods. Structured interview data were used to select a group of patients with comorbid BPD (n=21) from a sample of outpatients presenting with MDE. This group was compared with a group of MDE patients without BPD (n=24) and with a group of community controls (n=20) using self-report data from the Personality Assessment Inventory (PAI), the revised Personality Diagnostic Questionnaire (PDQ), and the Beck Depression Inventory (BDI). Analyses revealed that the BPD group obtained significantly higher scores on PAI and PDQ scales measuring features of BPD and on the PAI Negative Impression Management scale. The severity and type of MDE symptoms reported on the PAI and BDI did not differentiate the clinical groups. These data show that useful information for the diagnosis of BPD during depressive episodes can be gathered from self-report assessment instruments like the PAI.     

An Examination of Information Quality as a Moderator of Accurate Personality Judgment

Information quality is an important moderator of the accuracy of personality judgment, and this article describes research focusing on how specific kinds of information are related to accuracy. In this study, 228 participants (159 female, 69 male; mean age = 23.43; 86.4% Caucasian) in unacquainted dyads were assigned to discuss thoughts and feelings, discuss behaviors, or engage in behaviors. Interactions lasted 25–30 min, and participants provided ratings of their partners and themselves following the interaction on the Big Five traits, ego‐control, and ego‐resiliency. Next, the amount of different types of information made available by each participant was objectively coded. The accuracy criterion, composed of self‐ and acquaintance ratings, was used to assess distinctive and normative accuracy using the Social Accuracy Model. Participants in the discussion conditions achieved higher distinctive accuracy than participants who engaged in behaviors, but normative accuracy did not differ across conditions. Information about specific behaviors and general behaviors were among the most consistent predictors of higher distinctive accuracy. Normative accuracy was more likely to decrease than increase when higher‐quality information was available. Verbal information about behaviors is the most useful for learning about how people are unique.     

Age-Related Differences in Identity Style: A Cross-Sectional Analysis

The Identity Style Inventory–Revised for a Sixth-Grade Reading Level (ISI-6G) was administered to samples of community college students (N = 99) and middle school and high school students (N = 320). Tests of between-groups differences indicated that the college sample had a significantly lower mean diffuse-avoidant score on the ISI-6G than the middle and high school sample. In terms of actual assignment to identity styles, college students were significantly more likely to be classified as informational or normative, while the younger students were more likely to be diffuse-avoidant. The mean ages of participants for each of the three identity styles were compared, and it was found that diffuse-avoidant participants had the lowest mean age (15.54 years), while individuals with an informational orientation had the highest mean age (17.20 years). Results suggest that, in general, identity style evolves with age and maturity and the general trajectory or progression involves movement away from a diffuse-avoidant orientation. Findings are discussed in terms of current knowledge of neurocognitive development during adolescence and early adulthood.     

The error statistical philosopher as normative naturalist

We argue for a naturalistic account for appraising scientific methods that carries non-trivial normative force. We develop our approach by comparison with Laudan’s (American Philosophical Quarterly 24:19–31, 1987, Philosophy of Science 57:20–33, 1990) “normative naturalism” based on correlating means (various scientific methods) with ends (e.g., reliability). We argue that such a meta-methodology based on means–ends correlations is unreliable and cannot achieve its normative goals. We suggest another approach for meta-methodology based on a conglomeration of tools and strategies (from statistical modeling, experimental design, and related fields) that affords forward looking procedures for learning from error and for controlling error. The resulting “error statistical” appraisal is empirical—methods are appraised by examining their capacities to control error. At the same time, this account is normative, in that the strategies that pass muster are claims about how actually to proceed in given contexts to reach reliable inferences from limited data.     

Concurrent validity of the Personality Assessment Inventory Borderline scales in patients seeking dialectical behavior therapy

The purpose of this study was to explore the usefulness of the Personality Assessment Inventory (PAI; Morey, 1991) Borderline full scale (BOR) and subscales in the assessment of patients being evaluated for dialectical behavior therapy (DBT; Linehan, 1993).We administered 67 patients both the PAI and the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; American Psychiatric Association, 1994) Structured Clinical Interview for Axis II disorders (SCID-II; First, Spitzer, Gibbon, Williams, & Benjamin, 1997). Point biserial correlations showed a significant relationship between the presence of borderline personality disorder (BPD) and scores on the BOR and Schizophrenia (SCZ) scales. A regression analysis showed that among the BOR subscales, those measuring identity disturbance, self-harming behavior, and negative relationships were significantly related to the total number of SCID-II BPD criteria. Diagnostic efficiency statistics between the BOR scale and the number of SCID-II BPD criteria indicated that a T score cutoff of 65 optimally differentiates patients who do and do not meet criteria for BPD. The relationship between BOR and SCID-II BPD demonstrates the concurrent validity of the PAI and shows its usefulness in this setting.     

Equity Sensitivity Revisited: Contrasting Unidimensional and Multidimensional Approaches

Purpose  Past research has shown little support for direct relationships between equity sensitivity and various equity-relevant criteria. Recent work by Davison and Bing (J Manag Issues 20: 131–150, 2008) suggests that equity sensitivity consists of separate input- and outcome-focus dimensions and that these dimensions are associated with such criteria in an interactive fashion. The current study extends this research by theoretically strengthening and empirically testing their two-dimensional model. Design/methodology/approach  We surveyed adults who were working at least 30 h a week at three time periods to temporally separate measurement of predictors and criteria (n = 172). Findings  Results provide support for the two-dimensional model. Input and outcome focus interacted to explain variance in individuals’ satisfaction and self-reported job performance even after controlling for demographic characteristics, personality, and social desirability. By contrast, the original ESI only significantly predicted one of 10 dependent variables. Implications  Whereas a ratio has been historically used as the basis for evaluating equity, employing independent dimensions and investigating their interaction seems more appropriate to assess individuals’ equity sensitivity. The current study suggests a multidimensional measure of equity sensitivity may better reflect the original theoretical underpinnings of the construct. Originality/value  The current study enhances our understanding of equity theory in general, and equity sensitivity in particular, by drawing attention to the multidimensional nature of the equity sensitivity construct. In particular, it extends the work of Davison and Bing (J Manag Issues 20: 131–150, 2008) by revisiting Huseman et al.’s (Acad Manag Rev 12: 222–234, 1987) original conceptualization of equity sensitivity. In doing so, we broaden its utility as a potential unique predictor of organizationally relevant criteria.     

Introduction to the special issue on the personality assessment inventory

This special issue of the Journal of Personality Assessment brings together 13 new research studies on the Personality Assessment Inventory (PAI; Morey, 1991) that should inform users and stimulate future empirical activity with this measure. In 4 articles, authors evaluate the validity scales and indexes of the PAI using both analog and criterion designs and samples from a variety of clinical and forensic settings. In a 5th article, the authors describe a novel approach to profile interpretation using two PAI negative distortion measures. The authors present applications of the PAI to new populations and problems including a German translation of the PAI and profile information for male batterers and victims of head injury. The authors of 2 studies extend research on the validity of the PAI for the assessment of borderline personality disorder. In the final 3 studies, the authors evaluate the validity of PAI measures of violence and aggression to predict subsequent aggressive behavior and institutional misconduct. Finally, the authors offer several suggestions for future research with the PAI.     

Abrasive personality disorder: Definition and diagnosis

This article advances a proposal for a newly identified type of personality disorder. While, like some of the other major personality disorders, the abrasive personality disorder (AbPD) shares some features with other Axis II disorders, it may however be considered as possessing sufficient idiosyncratic features as to warrant a separate classification. There are few documented discussions of this disorder within the historical confines of scientific psychology, however a good deal of attention is being focused currently in the popular press, under the rubric of “difficult people,” “control freaks,” and the like. The disorder is defined, its distinguishing characteristics delineated, with theoretical discussion provided. Some rudimentary assessment approaches are noted, with a call for research in this virgin territory.     

Do men with excessive alcohol consumption and social stability have an addictive personality?

The existence of an "addictive" personality has been extensively debated. The current study investigated personality in male individuals with excessive alcohol consumption (n=100) in comparison to a population-based control group (n=131). The individuals with excessive alcohol consumption were recruited by advertisements in a regional daily newspaper and controls from a population based Swedish Twin Registry. Personality was assessed by the Karolinska Scales of Personality (KSP). Comparisons were made with normative data. Furthermore, by using a multivariate projection-based approach (Principal Component Analysis; PCA), hidden structures of traits and possible relationships among the individuals with excessive consumption and the controls was investigated. The individuals with excessive alcohol consumption as well as the controls had mean values within the normative range in all scales of the KSP. Moreover, the PCA analysis revealed no systematic between-group separation. Taken together, this result demonstrates that male individuals with excessive alcohol consumption do not have a personality different from that of a general population, which supports the notion of no "addictive personality".     

Some supplementary methods for the analysis of WAIS-IV index scores in neuropsychological assessment

Objectives. To develop supplementary methods for the analysis of the Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) in neuropsychological assessment. Design and Methods. Psychometric. Results. The following methods are made available: (a) provision of traditional confidence intervals (CIs) on index scores, (b) expression of the endpoints of CIs as percentile ranks; (c) quantification of the number of abnormally low index scores exhibited by a case and accompanying estimate of the percentage of the normative population expected to exhibit at least this number of low scores; (d) quantification of the reliability and abnormality of index score deviations from an individual's index score mean (thereby offering an alternative to the pairwise approach to index score comparisons available in the WAIS-IV manual); (e) provision of CIs on an individual's deviation scores or pairwise difference scores, (f) estimation of the percentage of the normative population expected to exhibit at least as many abnormal deviations or abnormal pairwise differences as a case; and (g) calculation of a case's Mahalanobis distance index (MDI), thereby providing a multivariate estimate of the overall abnormality of an index score profile. With the exception of the MDI, all the methods can be applied using tables provided in this paper. However, for ease and speed of application, and to reduce the possibility of clerical error, all the methods have also been implemented in a computer program. Conclusions. The methods are useful for neuropsychological interpretation of the WAIS-IV.     

Examination of the reliability and validity of the personality assessment inventory

The reliability, discriminant validity, and construct validity of the Personality Assessment Inventory (PAI) — a multidimensional self-report measure of abnormal personality traits — were examined within the Australian context. Subjects included 151 normals, 30 alcoholics, and 30 schizophrenic patients. A subsample of 70 nonpsychiatric adults responded to the PAI items twice over a test-retest interval of 28 days. The resulting median retest coefficient was 0.7, indicating less than optimal stability. The median alpha (KR₂₁) coefficient was 0.8, suggesting somewhat narrow measurement scales. A significant multivariate main effect was obtained across groups after the effects of age and gender were removed. Multiple comparisons for each of the PAI scales revealed significant differences between the respective groups, as discussed. A higher-order scale factoring did not strongly support the purported PAI structure. In reanalyses of the correlation matrices included in the Professional Manual, the purported PAI factor structure was unable to be replicated for the standardization clinical sample (N=1246), and a confirmatory factor analysis using the normative (validation) correlational data (N=1000) revealed poor fit indices, raising further concerns about construct validity.     

Analysis of WAIS-IV index score scatter using significant deviation from the mean index score

The Wechsler Adult Intelligence Scale-Fourth Edition (WAIS-IV) does not include verbal IQ and performance IQ scores, as provided in previous editions of the scale; rather, this edition provides comparisons among four index scores, allowing analysis of an individual's WAIS-IV performance in more discrete domains of cognitive ability. To supplement the pairwise index score comparisons included in the WAIS-IV manuals, this article describes the use of the mean of the four index scores (the average index score) as a baseline for analyzing index score variability and as a method for identifying strengths and weaknesses within an individual's index score pattern. Davis's formula was used to calculate critical values for the identification of index scores with a statistically significant difference from the average index score. Subsequent analysis of the WAIS-IV normative sample indicates that variability in performance at the index score level is not uncommon in the general population. More than 70% of individuals in the normative sample have at least one index score that differs significantly from their mean index score. This variability in index score performance appears to have little relationship to age or gender, but it is strongly related to the full-scale IQ.     

Cognitive-Behavioral Therapy for Insomnia Co-Morbid with Hearing Impairment: A Randomized Controlled Trial

The purpose of the current study was to examine the effects of cognitive behavior therapy (CBT-I) for insomnia on patients with insomnia co-morbid with hearing impairment. A randomized controlled design was used with a 3-month follow-up. Thirty-two patients with insomnia co-morbid with hearing impairment were randomized to either CBT-I or a waitlist condition (WLC). The primary outcome was insomnia severity. Secondary outcomes were sleep diary parameters, dysfunction, anxiety, and depression. Compared to WLC, CBT-I resulted in lower insomnia severity at post-treatment and at follow-up (d = 1.18–1.56). Relative to WLC, CBT-I also led, at both assessment points, to reduced total wake time (d = 1.39) and increased sleep restoration (d = 1.03–1.07) and sleep quality (d = 0.91–1.16). Both groups increased their total sleep time, but no significant group difference emerged. Compared to WLC, CBT-I resulted in higher function (d = 0.81–0.96) and lower anxiety (d = 1.29–1.30) at both assessment points. Neither CBT-I nor WLC led to improvement on depression. Based on the Insomnia Severity Index, more CBT-I (53–77%) than WLC participants (0–7%) were treatment responders. Also, more CBT-I (24%) than WLC participants (0%) remitted. In patients with insomnia co-morbid with hearing impairment, CBT-I was effective in decreasing insomnia severity, subjective sleep parameters, dysfunction, and anxiety. These findings are in line with previous results on the effects of CBT-I in other medical conditions.     

Confirmatory Factor Analysis of the Behavioral and Emotional Rating Scale–2 (BERS-2) Parent and Youth Rating Scales

We confirmed the factor structure of the Behavioral and Emotional Rating Scale – 2nd Edition (BERS-2) with a normative parent and youth sample. The BERS-2, based on the Behavioral and Emotional Rating Scale (BERS), is a standardized instrument that assesses children's emotional and behavioral strengths. The original BERS was renormed to create a separate parent scale (Parent Rating Scale) and a youth self-report scale (Youth Rating Scale). In this study, we investigated whether the five-factor structure of the original BERS (i.e., interpersonal strengths, family involvement, intrapersonal strengths, school functioning, and affective strengths) could be replicated with normative parent and youth respondents. A total of 927 parents of students with and without disabilities and 1301 youth with and without disabilities volunteered to participate in the study. Confirmatory factor analysis was used to determine the extent to which the normative parent and youth data fit the original five-factor BERS structure. Results indicated that the five-factor structure demonstrated an acceptable fit with the normative parent and youth samples. Practical implications and future research ideas are discussed.     

Defending a Law of Peoples: Political Liberalism and Decent Peoples

In this paper I reconstruct and defend John Rawls' The Law of Peoples, including the distinction between liberal and decent peoples. A “decent people” is defined as a people who possesses a comprehensive doctrine and uses that doctrine as the ground of political legitimacy, while liberal peoples do not possess a comprehensive doctrine. I argue that liberal and decent peoples are bound by the same normative requirements with the qualification that decent peoples accept the same normative demands when they are reasonably interpreted and from their comprehensive doctrine, not from political liberalism. Normative standards for peoples appear in a law of peoples in two places: as internal constraints carried forward from political liberalism which regulate domestic affairs and as principles derived from a second original position that provide the normative ground for a society of peoples. This first source of normative standards was unfortunately obscured in Rawls' account. I use this model to defeat the claim that Rawls has accommodated decent peoples without sufficient warrant and to argue that all reasonable citizens of both liberal and decent peoples would accept the political authority of the state as legitimate. Although my reconstruction differs from Rawls on key points, such as modifying the idea of decency and rejecting a place for decent peoples within a second original position, overall I defend the theoretical completeness of political liberalism and show how a law of peoples provides reasonable principles of international justice. This paper explores theoretical ideas I introduced in embryonic form in a paper presented at the International Conference on Human Rights: Theoretical Foundations of Human Rights, 17–18 May, 2003, Mofid University (Qom, Iran). That paper, “Political Liberalism and Religious Freedom: Asymmetrical Tolerance for Minority Comprehensive Doctrines” (forthcoming in the Proceedings of the conference), addressed specific issues related to religious toleration, but left unexplored theoretical questions regarding the status of decent peoples. I wish to thank participants in the conference for their helpful feedback on my interpretation of Rawls' international political theory, especially Jack Donnelly, Michael Freeman, Stephen Macedo, Samuel Fleishacker, Omar Dahbour, Yasien Ali Mohamed, and Saladin Meckled-Garcia. In addition, I wish to offer my sincere appreciation to the Executive Committee of the Conference and especially to Sayyed Masoud Moosavi Karimi, Nasser Elahi, and Mohammad Habibi Modjandeh.
