RESUMO
Dr. John L. McNulty, born on January 25, 1955, in Bartlesville, Oklahoma, passed away on October 31, 2023, in Tulsa, Oklahoma, at the age of 68 years. Ever the pragmatist and always bringing a critical mindset to test use, Dr. McNulty coauthored seminal articles demonstrating the absence of predictive bias among African Americans. His commitment to diversity more recently focused on contemporary assessment with transgender and gender-diverse individuals. While Dr. McNulty's empirical work advanced the field of personality and psychopathology, his relationships with colleagues and mentees are his most lasting legacy. Dr. McNulty inspired many while he was here, and his memory will inspire many into the future. (PsycInfo Database Record (c) 2024 APA, all rights reserved).

This article describes the development, internal psychometric, and external validation studies on scales designed to measure the Personality Psychopathology Five (PSY-5) from MMPI-2 Restructured Form (MMPI-2-RF) items. Diverse and comprehensive data sets, representing various clinical and nonclinical populations, were classified into development and validation research samples. Item selection, retention, and exclusion procedures are detailed. The final set of PSY-5-RF scales contain 104 items, with no item overlap between scales (same as the original MMPI-2 PSY-5 scales), and no item overlap with the Demoralization scale. Internal consistency estimates are comparable to the longer MMPI-2 PSY-5 scales. Appropriate convergent and discriminant validity findings utilizing various self-report, collateral rating, and record review data are reported and discussed. A particular emphasis is offered for the unique aspects of the PSY-5 model: psychoticism and disconstraint. The findings are connected to the broader PSY-5 literature and the recommended review of systems (Harkness, Reynolds, & Lilienfeld, this issue) presented in this series of articles.

We outline a crisis in clinical description, in which atheoretical categorical descriptors, as in the Diagnostic and Statistical Manual of Mental Disorders (DSM), has turned focus away from the obvious: evolved major adaptive systems. Adaptive systems, at the core of a medical review of systems (ROS), allow models of pathology to be layered over an understanding of systems as they normally function. We argue that clinical psychology and psychiatry would develop more programmatically by incorporating 5 systems evolved for adaptation to the external environment: reality modeling for action, short-term danger detection, long-term cost-benefit projection, resource acquisition, and agenda protection. These systems, although not exhaustive, coincide with great historical issues in psychology, psychopathology, and individual differences. Readers of this journal should be interested in this approach because personality is seen as a relatively stable property of these systems. Thus, an essential starting point in ROS-based clinical description involves personality assessment. But this approach also places demands on scientist-practitioners to integrate across sciences. An ROS promotes theories that are (a) compositional, answering the question: What elements comprise the system?; (b) dynamic, answering: How do the elements and other systems interact?; and (c) developmental: How do systems change over time? The proposed ROS corresponds well with the National Institute of Mental Health's recent research domain criteria (RDoC) approach. We urge that in the RDoC approach, measurement variables should be treated as falsifiable and theory-laden markers, not unfalsifiable criteria. We argue that our proposed ROS promotes integration across sciences, rather than fostering the isolation of sciences allowed by atheoretical observation terms, as in the DSM.

The Personality Psychopathology-Five (PSY-5; Harkness & McNulty, 1994) is a model of individual differences relevant to adaptive functioning in both clinical and non-clinical populations. In this article, we review the development of the PSY-5 model (Harkness, 1992; Harkness & McNulty, 1994) and discuss the ways in which the PSY-5 model is related to and distinct from other 5-factor models. Using different methods and measures, the dimensions of the PSY-5 model have been constructively replicated (Lykken, 1968) by Tackett, Silberschmidt, Krueger, and Sponheim (2008) and by Watson, Clark, and Chmielewski (2008), and dimensions congruent with the PSY-5 have even been suggested for the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; Krueger et al., 2011). PSY-5 Scales can be scored from the Minnesota Multiphasic Personality Inventory-2 (MMPI-2; Butcher et al., 2001), the MMPI-Adolescent version (MMPI-A; Butcher et al., 1992), and the Restructured Form of the MMPI-2 (MMPI-2-RF; Ben-Porath & Tellegen, 2008). Because the largest body of research exists for the MMPI-2-based scales, we focus our review of the literature on the MMPI-2-based PSY-5 scales (Harkness, McNulty, & Ben-Porath, 1995), but we briefly cover the small, but growing, body of MMPI-A and MMPI-2-RF PSY-5 scales research. We show that the PSY-5 research literature includes a wide variety of psychometric methodologies as well as diverse samples and clinical problems. An integrative summary reprises the theory behind each PSY-5 construct and links it to the reviewed literature. Advantages and limitations of MMPI-2-based PSY-5 scales are discussed.

The short allele of the serotonin transporter gene (5-HTTLPR) is associated with greater negative emotionality. Given that emotion modulates pain, short allele carriers (s-carriers) may also demonstrate altered pain modulation. The present study used a well-validated emotional picture-viewing paradigm to modulate pain and the nociceptive flexion reflex (NFR, a measure of spinal nociception) in 144 healthy genotyped participants. As expected, pain/NFR responses were largest during unpleasant pictures and smallest during pleasant pictures. However, relative to l/l-carriers, s-carriers demonstrated greater pain inhibition during pleasant pictures and greater pain facilitation during unpleasant pictures. Neither emotional modulation of NFR nor NFR threshold was associated with 5-HTTLPR polymorphisms. Results also indicated that men who were s-carriers had a higher pain threshold and tolerance than other participants. Taken together, our results indicate 5-HTTLPR polymorphisms may influence pain modulation at the supraspinal (not spinal) level; however, the influence on pain sensitivity may be sex-specific.

The Minnesota Mutiphasic Personality Inventory-2 (MMPI-2)-based Personality Psychopathology-Five (PSY-5) scales provide an overview of personality individual differences. Several textbooks and a test report offer instruction on interpreting MMPI-2 PSY-5 scores. On the basis of an earlier item response theory article (S. V. Rouse, M. S. Finger, & J. N. Butcher, 1999), low scores on the PSY-5 Aggressiveness (AGGR) scale are not currently interpreted. Traditional statistical methods are supplemented with graphical, robust, and resistant methods in the study of 188 outpatient men and 287 outpatient women. With locally weighted regression smoothing, the AGGR scale appeared to bear approximately linear relationships to scales formed from therapist ratings of patients. Pearson correlations tested by t test for significance showed correspondence with robust bootstrapped tests. Low-cut subsamples of men and women at or below the 33rd normative percentile showed that resistant correlations with robust tests showed moderate convergence with traditional methods. Results clearly suggested that low AGGR scores on the PSY-5 should be interpreted as suggesting low aggressiveness and passive and submissive features. Resistant and robust analyses suggest that gradations of aggressiveness, even within a low AGGR score group, can be interpreted.

The author presents four essential Meehl lessons for personality assessment. First, Meehl's particular form of the integration of science and practice is described. Second, by outlining Meehl's Hedonic Capacity conjecture, Meehl's contribution to the inclusion of personality individual differences in generating the full clinical picture and in planning treatment is recognized. The third Meehl lesson is on the nature and importance of theory in test development and application programs. The fourth Meehl lesson is a more general epistemological lesson for psychology. Meehl's role in destroying the fantasy of an easy methodological formula for a scientific psychology is described. His program of taxometric research is shown to be an example of demanding greater material implications from theory. Meehl's corroboration index is described and contrasted with the p value of statistical significance testing.
