Resilient, undercontrolled, and overcontrolled personality prototypes among persons with spinal cord injury

A sample of 199 persons with spinal cord injury (SCI) were assessed on Big Five personality dimensions using the NEO Five-Factor Inventory (NEO-FFI; Costa & McCrae, 1992) at admission to an inpatient medical rehabilitation program. A cluster analysis of the baseline NEO-FFI yielded 3 cluster prototypes that resemble resilient, undercontrolled, and overcontrolled prototypes identified in many previous studies of children and adult community samples. Compared with normative samples, this sample had significantly fewer resilient prototypes and significantly more overcontrolled and undercontrolled prototypes. Undercontrolled individuals were the modal prototype. The resilient and undercontrolled types were better adjusted than the overcontrolled types, showing lower levels of depression at admission and higher acceptance of disability at discharge. The resilient type at admission predicted the most effective reports of social problem-solving abilities at discharge and the overcontrolled type the least. We discuss the implications of these results for assessment and interventions in rehabilitation settings.     

Inclusion of theory-relevant moderators yield the same conclusions as Sedikides, Gaertner, and Vevea (2005): A meta-analytical reply to Heine, Kitayama, and Hamamura (2007)

Heine, Kitayama and Hamamura (2007) attributed the Sedikides, Gaertner and Vevea (2005) findings to the exclusion of six papers. We report a meta-analysis that includes those six papers. The Heine et al . conclusions are faulty, because of a misspecified meta-analysis that failed to consider two moderators central to the theory. First, some of their effect sizes originated from studies that did not empirically validate comparison dimensions. Inclusion of this moderator evidences pancultural self-enhancement: Westerners enhance more strongly on individualistic dimensions, Easterners on collectivistic dimensions. Second, some of their effect sizes were irrelevant to whether enhancement is correlated with dimension importance. Inclusion of this moderator evidences pancultural self-enhancement: Both Westerners and Easterners enhance on personally important dimensions. The Sedikides et al . conclusions are valid: Tactical self-enhancement is pancultural.     

A Case for Homogeneity of Personality at the Occupational Level

The forces of attraction–selection–attrition have been hypothesized to create homogeneity of personality within organizations, and vocational choice theory predicts that these forces lead to a ‘modal personality’ within given occupations. This study compared the homogeneity of a set of personality characteristics for 6582 incumbents from eight organizations in eight occupations. The results indicated that (1) the homogeneity hypothesis was supported both within organizations as well as within occupations; and (2) the homogeneity within occupations was higher than that found in organizations.     

Ethics Issues with Private Research Ethics Boards: A Breakout Session at the 2009 NCEHR National Conference

Research Ethics Boards (REBs) provide oversight for Canadians that research projects will comply with standards of ethics if the studies are carried out as described in the documents that have been approved. While REBs have traditionally been affiliated with institutions such as universities and hospitals, a number of factors - including the increased volume of research being conducted outside academic centres - have resulted in the establishment of some private or independent REBs. This, in turn, has raised concerns about the credibility of REBs in the private sector and their capacity to handle issues around conflict of interest. This Breakout Session was an opportunity to hear the perspectives of people associated with institutional and private REBs and examine perceived problems with boards in the private sector, scrutinize theoretical and structural differences between types of REBs, and look at whether or not there is room for both institutional and private boards in the Canadian research review landscape.     

A Brief History of Dissonance Theory

Prior to the construction of the theory of cognitive dissonance, the dominant view in American experimental psychology held that behavior, including verbal attitude statements, was learned and shaped by rewards and/or punishments. Dissonance theory took a surprisingly different view by stating that behaviors and reasons for engaging in them could be strengthened by minimizing the very rewards or threatened punishments that produced the behaviors. Many hundreds of experimental studies later, the main argument of dissonance theory is well supported, although researchers disagree about the necessary and sufficient conditions. The present paper traces the major lines of research, including contributions from around the world, and the major controversies among some of the researchers.     

Verbal intelligence and self-regulatory competencies: Joint predictors of boys’ aggression

Two studies examined the interactive effect of receptive verbal intelligence measured by the Peabody Picture Vocabulary Test and self-regulatory competencies measured in the delay of gratification paradigm on boys’ aggression. Study 1 participants (N = 98) were middle school, low-income boys primarily ethnic minority. Participants for Study 2 (N = 59) were drawn from a treatment camp for boys from low-income neighborhoods with behavioral adjustment problems. In both studies, the interaction between verbal intelligence and self-regulation was significant such that verbal intelligence was associated with lower aggression to a greater extent among boys who had effective self-regulatory skills than among those who had ineffective self-regulatory skills. The implications of these findings for interventions and for a theory of risk factors in aggression are discussed.
