Structures of Personality and Their Relevance to Psychopathology: II. Further Articulation of a Comprehensive Unified Trait Structure

ABSTRACT There is increasing agreement that the current categorical system of personality disorders (PDs) in the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition (DSM‐IV; American Psychiatric Association, 2000) should be replaced by a trait dimensional scheme in DSM‐V. In particular, the consensus appears to be converging on a hierarchical Big Four model. The broad factors that form the apex of this hierarchy are essentially maladaptive variants of the Big Five traits of normal personality, minus Openness. We argue that this Big Four model is incomplete, however, in that it fails to model characteristics related to the “odd or eccentric” Cluster A PDs adequately. We report the results of three studies that examine these odd, eccentric characteristics in relation to basic dimensions of normal and abnormal personality. The results of these studies establish the existence of an Oddity factor that is (a) broader than the Cluster A traits and (b) distinct from Openness and the other Big Five dimensions. Consequently, its addition yields an alternative five‐factor model of personality pathology (considering only abnormal traits) and an expanded, integrated Big Six taxonomy that subsumes both normal and abnormal personality characteristics.     

Resolving ambiguity: a psycholinguistic approach to understanding prosody processing in high-functioning autism

Individuals with autism exhibit significant impairments in prosody production, yet there is a paucity of research on prosody comprehension in this population. The current study adapted a psycholinguistic paradigm to examine whether individuals with autism are able to use prosody to resolve syntactically ambiguous sentences. Participants were 21 adolescents with high-functioning autism (HFA), and 22 typically developing controls matched on age, IQ, receptive language, and gender. The HFA group was significantly less likely to use prosody to disambiguate syntax, but scored comparably to controls when syntax alone or both prosody and syntax indicated the correct response. These findings indicate that adolescents with HFA have difficulty using prosody to disambiguate syntax in comparison to typically developing controls, even when matched on chronological age, IQ, and receptive language. The implications of these findings for how individuals with autism process language are discussed.     

Engaging African Americans in Therapy: Integrating a Public Policy and Family Therapy Perspective

The field of marriage and family therapy faces a growing imperative to reach historically underserved populations. African Americans are a prime example of a minority group in the United States that continues to be underserved by the current mental health system. We integrate Andersen’s (1995, Journal of Health and Social behavior, 36, 1–10) public policy model of health service use with Fox et al. (1995, Journal of Health Care for the Poor and Underserved, 6, 434–468) revision of the rural de facto mental health services model (Regier and Goldberg, 1978, Archives of General Psychiatry, 35, 685–693) to develop a more inclusive and culturally sensitive framework that captures salient factors influencing African Americans’ entry into and engagement in therapy. Recommendations for overcoming barriers and suggestions for future research are presented.     

Can organisational safety climate and occupational stress predict work-related driver fatigue?

Road crashes are a significant cause of work-related injury and death. Driver fatigue is thought to cause 20–30% of fatal crashes. The current study utilised a survey to examine the relationship between safety climate, occupational stress and work-related driver fatigue. Drivers (n = 219) from two government organisations responded to items from the job-related tension scale [Kahn, R. L., Wolfe, D. M., Quinn, R. P., & Snoek, J. D. (1964). Organisational stress: Studies in role conflict and ambiguity. Malabar, FL: Krieger Publishing], safety climate questionnaire [Glendon, A., & Litherland, D. (2001). Safety climate factors, group differences and safety behaviour in road construction. Safety Science, 39, 157–188] and purpose-designed items on fatigue-related behaviour. Outcome measures were current self-reported, fatigue-related behaviour and self-reported ‘near (crash) misses’ during the previous 6 months. Together, occupational stress and safety climate predicted fatigue-related behaviour, accounting for 29% of the variance over and above that explained by control variables. Further, logistic regression revealed occupational stress and safety climate to be significant predictors of fatigue-related near misses. Safety climate emerged as a stronger predictor of both fatigue-related behaviour and near misses than occupational stress. Results suggest that organisations can play a part in improving the safety-related behaviours of their workforce through attention to safety climate and occupational stress.     

Friend or Foe? Differential Use of the Self‐Based Heuristic as a Function of Relationship Satisfaction

ABSTRACT We report two studies investigating whether relationship satisfaction differentially influences the use of the "self-based heuristic" (SBH) or the degree to which an individual's own characteristics contribute to ratings of another's personality. Individuals rated themselves, a friend, and a person with whom they have experienced significant conflict (a "foe"); ratings were made on measures of the Big Five and trait affectivity. Replicating previous research, judges made greater use of the SBH when rating trait affectivity than when rating the Big Five. In addition, individuals were more likely to utilize the SBH when rating friends than when rating foes. Further, relationship satisfaction made significant independent contributions in accounting for the variance in trait ratings of others. These findings extend our understanding of the mechanisms involved with person perception beyond observable trait-related information.     

Self-discrepancy and chronic social self-consciousness: Unique and interactive effects of gender and real–ought discrepancy

Drawing on theories of self-discrepancy and self-focused attention, two studies tested the associations between self-discrepancy and chronic social self-consciousness (CSSC), a trait-like view of the self as a social object. In Study 1, hierarchical regression analyses demonstrated that real/own-ought/other discrepancy was uniquely associated with CSSC independent of impression management, neuroticism, and real/own-ideal/own discrepancy among women but not men. In Study 2, the unique relation between real/own-ought/other discrepancy and CSSC was replicated in a larger sample of women after controlling several robust competing variables including the importance of physical appearance. Discussion considers real/own-ought/other discrepancy as a unique psychological predictor of taking a chronic view of the self as a social object among women.     

Psychometric Analysis and Tentative Shortening of Survey of Personal Beliefs

The Survey of Personal Beliefs (SPB) is a frequently used measure of irrational beliefs, but can display less than ideal psychometric properties. In the first study of the present project, the five subscales of the SPB correlated as expected with higher levels of perfectionism, shame, and guilt. A confirmatory factor analysis, nevertheless, revealed that these subscales did not adequately describe responding on the SPB, and internal reliability for some subscales was poor. An abbreviated 12-item version of the SPB was more reliable than the subscales and generally as valid as the full 50-item instrument. With a second data set, the shortened version of the SPB was more consistent than the full 50-item scale in correlating positively with at least some measures of maladjustment that included depression, anxiety, neuroticism, and alexithymia. Future researchers may want to utilize the shorter 12-item version of the SPB as a more convenient and psychometrically acceptable measure of irrational beliefs.     

Is optimal vision required for the successful execution of an interceptive task?

The importance of optimal visual function in demanding interceptive tasks is far from established. The aim of the study was to determine whether induced myopic blur and hence sub-optimal visual function would give rise to a detrimental effect on performance in the execution of an interceptive task. The batting performance of grade level cricket players was assessed facing a bowling machine whilst wearing contact lenses of four different refractive conditions (plano (nil), +1.00, +2.00 and +3.00D over-refraction), inducing increasing amounts of myopic blur. Performance for each condition was assessed based both on the shot quality against each delivery judged by a qualified cricket coach blind to each condition, along with an evaluation of the quality of ball-bat contact for each delivery. No significant change was found in batting performance with the introduction of +1.00 and +2.00D of induced myopic blur. A +3.00D over-correction was required before any significant decrease in batting performance was detected, demonstrating that batters needed to be essentially legally blind (as simulated through the use of the +3.00D over-refraction) before there was any significant measurable decrement in batting performance. We concluded that optimal visual correction is not necessarily required for optimal performance in a demanding interceptive task, and that the human perceptual-motor system is capable of compensating for marked alterations in input.
