Assessing normal and abnormal personality functioning: strengths and weaknesses of self-report, observer, and performance-based methods

Assessing personality characteristics; distinguishing the boundaries between normal and abnormal functioning; identifying impairment in the domains of work, interpersonal relationships, and emotional state due to maladaptive personality traits; and translating these findings into effective, appropriate treatment interventions is a complicated endeavor. Valid, reliable conclusions about an individual's personality functioning and adjustment cannot be reached unless one has accurate information about that person's patterns of behavior, cognitions, emotions, and interpersonal relationships. I discuss strengths and weaknesses of assessment approaches utilizing explicit assessment methods, such as self-report measures and clinical interviews; information obtained from knowledgeable observers; and performance-based, implicit assessment methods such as the Rorschach Comprehensive System (Exner, 2003). In contrast to explicit methods of assessment, implicit methods can provide salient information about a personality construct whether or not individuals have accurately conceptualized that construct, have weighed how the construct describes them, are self-aware, and are willing to openly provide information relevant to that construct. I propose that the accuracy of conclusions about an individual's personality style, problems in adjustment, and treatment needs may be improved if conclusion are based on a multimethod assessment approach that incorporates information gathered using explicit assessment methods, information provided by significant others, and data from performance-based or implicit measures of personality.     

Clarification and elaboration on evidence-based practice in psychology

Responds to comments by D. C. Wendt and B. D. Slife, P. H. Hunsberger, and R. B. Stuart and S. O. Lilienfeld regarding the report by the APA Presidential Task Force on Evidence-Based Practice entitled Evidence-based practice in psychology. The goal of the task force was to create a scheme that would suggest how evidence should be used to design and offer services that will benefit patients and to assure the public and the health care system that psychologists are providing evidence-based services. There were and will continue to be many scientific and philosophical issues inherent in any such enterprise, and agreement by all psychologists with every aspect of EBPP may not be possible. Nevertheless, the APA's EBPP policy and the report that accompanied it are remarkably inclusive of various perspectives while remaining unambiguous about the need to use evidence in a way that leads to effective services. What is needed at this point are clinically relevant evidence and investigations of how such evidence can be used to best benefit those served by psychological interventions.     

Mental extrapolation in patterns constructed from memory

Finke and Pinker (1982, 1983) showed subjects an array of dots followed by an arrow in a blank field, and asked them to determine whether the arrow pointed to any of the previously seen dots. Response times were linearly related to the distance between the arrow and the nearest dot, suggesting that subjects spontaneously used an internal scanning or extrapolation process to perform the task. We replicate and extend this finding by varying the retention interval, and by employing a paradigm in which subjects’ eyes are closed and the arrows are described to them using a coordinate scheme. We also show that subjects are unable to predict the form of the data when the task simply is described to them. Results suggest that mental scanning along a straight path can be performed on images reconstructed from memory, and that it does not depend on the ongoing perception of a continuous surface, on physical eye movements, or on demand characteristics.     

Feedback during exposure to inescapable shocks and subsequent shock-escape performance

In two experiments, we assessed the ability of a feedback stimulus during helplessness training to reduce the performance deficits common to inescapable shock. In each experiment, four groups of rats were exposed to either escapable shock (E), inescapable shock with a feedback stimulus following shock termination (Y-FS), inescapable shock with no feedback stimulus (Y-NFS), or no shock (N). The feedback stimulus eliminated the interference effects of inescapable shock when tested with an FR-3 lever press escape task (Experiment 1) or on an FR-1 task with a 3-s delay between the response and shock termination (Experiment 2). These results suggest that stress-induced biochemical changes may mediate the interference effects seen in inescapably shocked rats.     

A DEVELOPMENTAL DEFICIT IN LOCALIZING OBJECTS FROM VISION

Abstract— We describe a college student, A. H., with a developmental deficit in determining the location of objects from vision. The deficit is selective in that (a) localization from auditory or tactile information is intact, (b) A H reports the identity of mislocalized objects accurately, (c) visual localization errors preserve certain parameters of the target location, and (d) visual localization is severely impaired under certain stimulus conditions, but nearly intact under other conditions. These results bear on the representation and processing of location information in the visual system, and also have implications for understanding developmental dyslexia.     

The original MMPI and Colligan Norms revisited

Norms developed by Colligan, Osborne, Swenson, and Offord (1983) and others at the Mayo Clinic for the MMPI overcome criticisms that the MMPI is not useful in 2003 and representative. This study ascertained the classification of MMPI profiles of clinicians. Mayo Clinic norms are warranted in view of the similar classifications made using both methods based on the same MMPI data.     

Pavlovian processes do mediate control of the “advance” response strategy

Two parallel experiments used pigeons in a transfer of control design to determine the basis of the transfer of the use of the “advance strategy” across successive discriminations (W. K. Honig & H. Lindsay, Learning and Motivation, 1975, 6, 157–178). Pigeons were first trained under instrumental contingencies to use an “advance” response to maximize their exposure to S^D and minimize their exposure to S^Δ. Then orthogonal stimuli (key lights in Experiment 1 and diffuse illuminations in Experiment 2) were independently established through separate discriminative Pavlovian procedures as CS+ and CS? or as CS^o's. Later in special tests, it was demonstrated that the associative values of the Pavlovian CS's were a major factor governing the use of the advance strategy: only pigeons exposed to $\text{CS+}\text{CS?}$ used the advance response to regulate their exposure to either CS. Although these experiments showed that the necessary and sufficient conditions for utilization of the advance strategy are the Pavlovian associative values of the discriminative stimuli, opportunity for differential “operant” responding during the discriminative stimuli seems to be a contributor to the optimal use of the advance response across successive discriminations.     

Introduction

This issue of Clinical Child and Family Psychology Review, Children Exposed to Domestic Violence: Current Status and Research Directions, addresses the current status of our knowledge as well as critical research needs in the area of children exposed to domestic violence. Although much has been learned in recent years about children exposed to violence, significant research gaps remain, the identification of which may help to build a more complete and rigorous science base in this area. This journal issue represents the distillation of a 3-day workshop on children exposed to violence, held in July of 2002, that identified what is known about children exposed to violence and what this information tells us about future research directions. Although many federal agencies have supported some research in this area, there is a need for more targeted attention on the topic, particularly with regard to measurement, sampling, and interventions/services. The papers in this issue were selected with these themes in mind. Although no single issue could cover the entire field, we intend to offer a representative sample of where we are and where we need to go with the hope of stimulating additional thought, collaboration, and research in this important area.     

A Study of Panic Attacks in University Students of Iran

This study examined the parameters of panic, fear, and avoidance among university students in Iran. Data were collected from 347 students using Farsi translations of the Panic Attack Questionnaire, Beck Depression Inventory, Taylor Manifest Anxiety Scale, State-Trait Anxiety Inventory, and Anxiety Sensitivity Index. Thirty-eight percent of participants reported panic attacks in the past year and 21.4% reported panic attacks in the past 4 weeks when prompted by a broad definition of panic. Men and those with unexpected panic reported greater panic severity whereas women with panic attacks reported greater situational fear and avoidance. Panickers who satisfied DSM-III-R panic disorder (PD) criteria reported greater lifestyle restriction and general psychopathology. The findings provide tentative support for cross-cultural similarity in panic phenomenology and the validity of DSM-III-R PD criteria among university students in Iran. The results are discussed by reference to nonclinical panic research and general themes of Iranian culture.
