DSM-5 personality traits and DSM-IV personality disorders

Two issues pertinent to the Diagnostic and Statistical Manual of Mental Disorders (5th ed.; DSM-5) proposal for personality pathology, the recovery of DSM-IV personality disorders (PDs) by proposed DSM-5 traits and the validity of the proposed DSM-5 hybrid model, which incorporates both personality pathology symptoms and maladaptive traits, were evaluated in a large undergraduate sample (N = 808). Proposed DSM-5 traits as assessed with the Personality Inventory for DSM-5 explained a substantial proportion of variance in DSM-IV PDs as assessed with the Personality Diagnostic Questionnaire-4+, and trait indicators of the 6 proposed DSM-5 PDs were mostly specific to those disorders with some exceptions. Regression analyses support the DSM-5 hybrid model in that pathological traits, and an indicator of general personality pathology severity provided incremental information about PDs. Findings are discussed in the context of broader issues around the proposed DSM-5 model of personality disorders.     

Do agreeableness and neuroticism explain age differences in the tendency to forgive others?

Previous research has shown that age is positively related to a dispositional tendency to forgive others. The present investigation tested the hypothesis that agreeableness and neuroticism partially mediate the association between age and forgivingness. Data from two representative cross-sectional samples of adults were used to test this hypothesis. Results from Study 1 (N = 962, age range: 19-84 years) support the hypothesis, indicating that agreeableness and neuroticism explained, in part, age differences in tendencies to forgive. Study 2 (N = 451, age range: 20-83 years) replicated and extended the results by including transgression occurrences as a third mediator. The results showed that agreeableness and neuroticism explain the association between age and the tendency to forgive others over and above the effect of transgression occurrences.     

Coming to terms: quantifying the benefits of linguistic coordination

Sharing a public language facilitates particularly efficient forms of joint perception and action by giving interlocutors refined tools for directing attention and aligning conceptual models and action. We hypothesized that interlocutors who flexibly align their linguistic practices and converge on a shared language will improve their cooperative performance on joint tasks. To test this prediction, we employed a novel experimental design, in which pairs of participants cooperated linguistically to solve a perceptual task. We found that dyad members generally showed a high propensity to adapt to each other's linguistic practices. However, although general linguistic alignment did not have a positive effect on performance, the alignment of particular task-relevant vocabularies strongly correlated with collective performance. In other words, the more dyad members selectively aligned linguistic tools fit for the task, the better they performed. Our work thus uncovers the interplay between social dynamics and sensitivity to task affordances in successful cooperation.     

The Hierarchical Structure and Construct Validity of the PID‐5 Trait Measure in Adolescence

The DSM‐5 may be the first edition that enables a developmental perspective on personality disorders because of its proposal to include a trait assessment in the Axis II section. The current study explores the reliability, structure, and construct validity of the Personality Inventory for DSM‐5 (PID‐5; Krueger, Derringer, Markon, Watson, & Skodol, 2012) in adolescents, a measure that assesses the proposed DSM‐5 traits. A community sample of Flemish adolescents (N = 434; 44.7% male) provided self‐reports on the PID‐5 and the Dimensional Personality Symptom Itempool (DIPSI; De Clercq, De Fruyt, Van Leeuwen, & Mervielde, 2006). Results indicate an acceptable reliability for the majority of the PID‐5 facets and a tendency toward structural convergence of the adolescent PID‐5 structure with the adult proposal. Convergent validity with age‐specific facets of personality pathology was generally supported, but discriminant validity appeared to be low. Beyond the findings that support the applicability of the PID‐5 in adolescents, developmental issues may be responsible for specific differences in the adolescent PID‐5 structure, the rather poor discriminant validity of the PID‐5, and the lower reliability of a small number of PID‐5 facets. These results indicate that further research on the validity of the PID‐5 in younger age groups is required.     

IQ and Scores on the Mini-Mental State Examination (MMSE): Controlling for Effort and Education Among Geriatric Inpatients

ABSTRACT

The Mini-Mental State Examination (MMSE) and the Peabody Picture Vocabulary Test, Third Edition (PPVT-III) were administered to 76 Extended Care Center inpatients of a Veterans Affairs Medical Center, 56 of whom did not carry a diagnosis associated with brain impairment, and 20 of whom had a diagnosis associated with degenerative or cerebrovascular conditions. MMSE and PPVT-III scores, the latter of which estimates verbal IQ, were significantly correlated in both groups, even when controlling for the effects of education. This correlation was attenuated, but remained significant, in the face of varying levels of patient effort. The findings of this study support earlier findings, which also suggest that interpretation of “impaired” performance on the MMSE for those with IQ scores below 90 should be interpreted with caution. Average MMSE scores for Wechsler IQ classifications are provided.     

The reminiscence bump in older adults' life story transitions

Older adults' memories of events that occurred in adolescence and early adulthood are over-represented compared to other lifetime periods. Prior research on this reminiscence bump has focused on qualities of individual memories. The present study used a novel interview method to examine the potential role played by mental representations of extended lifetime periods. Older adults provided oral life stories, and they divided their transcribed narratives into “chapters”. Participants' ages at chapter beginnings and endings showed pronounced reminiscence bumps. The results are consistent with the idea that personal episodes occurring near the boundaries of extended lifetime periods receive preferential processing that enhances long-term memory.     

Consuming experience: Why affective forecasters overestimate comparative value

The hedonic value of an outcome can be influenced by the alternatives to which it is compared, which is why people expect to be happier with outcomes that maximize comparative value (e.g., the best of several mediocre alternatives) than with outcomes that maximize absolute value (e.g., the worst of several excellent alternatives). The results of five experiments suggest that affective forecasters overestimate the importance of comparative value because forecasters do not realize that comparison requires cognitive resources, and that experiences consume more cognitive resources than do forecasts. In other words, because forecasters overestimate the extent to which they will be able to think about what they did not get while experiencing what they got.     

Optimizing subjective measures of consciousness

Dienes and Seth (2010) conclude that confidence ratings and post-decision wagering are two comparable and recommendable measures of conscious experience. In a recently submitted paper, we have however found that both methods are problematic and seem less suited to measure consciousness than a direct introspective measure.Here, we discuss the methodology and conclusions put forward by Dienes and Seth, and why we think the two experiments end up with so different recommendations.     

Proactive coping,gratitude, and posttraumatic stress disorder in college women

Abstract

This study investigated relationships among proactive coping, positive emotions, and posttraumatic stress disorder (PTSD) symptom severity for 182 undergraduate women with trauma histories. Participants were administered the Life Events Checklist (LEC), PTSD Checklist, Proactive Coping Inventory, Proactive Attitude Scale, General Perceived Self-Efficacy Scale, and measures of posttrauma gratitude and emotional growth. An Exploratory Factor Analysis (EFA) with proactive coping, proactive attitude, and self-efficacy items indicated a one-factor solution. The proactive coping style factor and posttrauma gratitude were independently negatively associated with current PTSD symptom level, above and beyond the effects of trauma severity, trauma history, and time elapsed since the trauma. The implications of these results for future research and understanding of the development of PTSD and its treatment are discussed.
