Computerized adaptive personality assessment: an illustration with the Absorption scale

This article introduces the theory behind and applications of adaptive personality assessment based on the item response theory. Two adaptive testing strategies were compared: (a) fixed test length and (b) clinical decision. Real-data simulations, based on the item responses from 1,000 subjects who had previously taken the 34-item Absorption scale (Tellegen, 1982) by means of paper-and-pencil format, were used to illustrate these strategies. Results suggest that computerized adaptive personality assessment works impressively well. With the fixed-test-length strategy, a 50% savings in administered items was achieved with little loss of measurement precision. In the clinical-decision testing strategy, individuals who were extreme on the Absorption trait were identified with perfect accuracy using, on average, 25% of the available items. The implications of these results for personality research and assessment are discussed.     

Computerized adaptive assessment of personality disorder: introducing the CAT-PD project

Assessment of personality disorders (PD) has been hindered by reliance on the problematic categorical model embodied in the most recent Diagnostic and Statistical Model of Mental Disorders (DSM), lack of consensus among alternative dimensional models, and inefficient measurement methods. This article describes the rationale for and early results from a multiyear study funded by the National Institute of Mental Health that was designed to develop an integrative and comprehensive model and efficient measure of PD trait dimensions. To accomplish these goals, we are in the midst of a 5-phase project to develop and validate the model and measure. The results of Phase 1 of the project--which was focused on developing the PD traits to be assessed and the initial item pool--resulted in a candidate list of 59 PD traits and an initial item pool of 2,589 items. Data collection and structural analyses in community and patient samples will inform the ultimate structure of the measure, and computerized adaptive testing will permit efficient measurement of the resultant traits. The resultant Computerized Adaptive Test of Personality Disorder (CAT-PD) will be well positioned as a measure of the proposed DSM-5 PD traits. Implications for both applied and basic personality research are discussed.     

On the renaissance of personality assessment and personality theory

Both personality assessment and personality theory have experienced a significant decline in the past two or three decades, giving way to alternate professional interests by some, and being attacked as both empirically unsupportable and devoid of conceptual merit by others. Several tangible signs suggest that a resurrection is underway owing to position reversals by former critics, the changing character of patient populations, refinements in personality-oriented psychometric techniques, the refurbishing of analytic, interpersonal, and learning theories of personality, and the central role assigned personality disorders in the multiaxial format of the DSM-III. Looking toward the future, the paper proposes a series of comprehensive and parallel diagnostic criteria for the personality disorders to be included in either DSM-IIIR or DSM-IV.     

Developments in research in personality assessment

Progress in personality research requires an adequate data analysis link between concepts of what people are like and observations of how they are likely to behave. Advances in computer technology have strengthened this link but also have made it necessary for investigators to be wary of lack of selectivity and trivialization in their research designs.     

Adolescent bullying and personality: An adaptive approach

From an evolutionary perspective, bullying behavior may be viewed as adaptive in nature. Moreover, as bullies may utilize both prosocial and aggressive means to achieve desired goals, they likely exhibit specific personality traits that allow for this bistrategic approach to survival. Therefore, after accounting for general aggression levels, bullying should be negatively associated with personality traits such as fairness and modesty (Honesty-Humility), but unrelated to traits such as forgiveness and tolerance (Agreeableness). Additionally, the intentional nature of the behavior suggests that bullying should be positively associated with instrumental, but not reactive, aggression. A sample of 310 adolescents completed measures of bullying, personality, and instrumental/reactive aggression. Results supported the hypotheses and are interpreted from an adaptive perspective.     

Cognitive processes and computerized personality assessment

Several implications of the cognitive viewpoint on personality are tested and the predictive validity of cognitive processing variables is assessed with judgements of parents and friends as a criterion measure. Free recall of items was related to cognitive schemas but reaction time during score recall was not. Ease of faking as well as response latency during faking were not related to cognitive schemas. Intra-individual analysis revealed a consistent non-linear relationship between response latency and item score in all conditions of the experiment. Although some cognitive process variables were correlated with the criterion measures, adding these variables to item scores did not always increase the predictive validity.     

The representation of four personality disorders by the schedule for nonadaptive and adaptive personality dimensional model of personality

This study examined the relationships of the Schedule for Nonadaptive and Adaptive Personality (SNAP) model of personality to 4 targeted personality disorders (PDs) in a large multisite sample of patients. Data were examined from 529 patients, who were assigned 1 of 5 primary diagnoses: borderline, schizotypal, avoidant, and obsessive-compulsive PDs and major depression without PD. Patients were administered the SNAP questionnaire and results were compared among diagnostic groups and between patient groups and nonclinical norms. Results indicated that the dimensions of the model appear to have considerable promise in differentiating normal from abnormal personality, particularly in the propensity of individuals with PDs to manifest negative affects and interpersonal detachment. Furthermore, the model appeared to successfully distinguish specific PDs, a property that represents a particular challenge for dimensional models of personality.     

Behavioral assessment of personality disorders

This article examines the definition of personality disorders (PDs) from a functional analytical framework and discusses the potential utility of such a framework to account for behavioral tendencies associated with PD pathology. Also reviewed are specific behavioral assessment methods that can be employed in the assessment of PDs, and how information derived from these assessments may be linked to specific intervention strategies.     

Evidence-based assessment of personality disorders

The purpose of this article is to provide a foundation for the development of evidence-based guidelines for the assessment of personality disorders, focusing in particular on integrated assessment strategies. The general strategy recommended herein is to first administer a self-report inventory to alert oneself to the potential presence of particular maladaptive personality traits followed by a semistructured interview to verify their presence. This strategy is guided by the existing research that suggests particular strengths of self-report inventories and semistructured interviews relative to unstructured clinical interviews. However, the authors also consider research that suggests that further improvements to the existing instruments can be made. The authors emphasize, in particular, a consideration of age of onset, distortions in self-perception and presentation, gender bias, culture and ethnicity, and personality change.     

Tackling ethical dilemmas in personality assessment.

This is a useful and thought-provoking special series about ethical issues in personality assessment. All of the articles in this special series are discussed. Some common themes and guidelines emerge from the articles. Given the complexity of many ethical dilemmas, it is important to follow a decision-making model. Several models are presented in this series. One must learn the rules and common ethical dilemmas that occur in the setting one is in. Current ethical problems should be used to prevent similar problems in the future. It is important to consult with other professionals before acting. Finally, work should be done to increase exposure of psychologists to common ethical problems in the field of personality assessment.     

The future of Rorschach in personality assessment

This article considers the Rorschach and its prospects for the next century in the context of two broad issues in psychology, as well as some test specific challenges confronting those interested in the Rorschach and its applications. The broad issues are the matters of personality as a topic of study in psychology, and the relation of findings about personality to treatment planning. The specific issues concern the definition of the Rorschach, research about the test stimuli, and the expansion of information concerning the interpretive usefulness of some structural variables that are poorly conceptualized or for which interpretation may be overly generalized. Some recommendations concerning collaborative research efforts are also offered.     

Religion,personality, and clinical assessment

Religion is an integral part of every person's life and occupies a central place in every personality. Viewing religion as referring to that which is of primary importance in one's life, one sees it as performing an integrative function, consolidating and ordering all of the inputs to personality, and giving consistency to one's behavior. Thus, an understanding of the individual and an assessment of his religion are necessary for a complete understanding of his problems.     

Facial asymmetry is negatively related to assertive personality but unrelated to dominant personality in men

Fluctuating asymmetry (FA) is a putative indicator of development instability in humans and other species, and some literature supports a women’s preference for low degree of FA in opposite sex (e.g., symmetrical face). Also some personality traits associated to social status (e.g., dominance and assertiveness) are attractive to women due to direct and indirect benefits associated to high status. The aim of this work was to study the relationship between facial FA and dominant and assertive personalities. We found a negative correlation between facial FA and assertive personality but not between facial FA and dominant personality. Moreover, we found a positive correlation between assertive and dominant personality. Our results suggest that a low facial FA and assertive personality can be related to be advertising desirable traits and high status in men in order to be more attractive to women. This study supports the evidence shown by previous works which shows that a low facial FA is related with socially desirable and attractive aspects of personality.
