The interacting roles of testosterone and challenges to status in human male aggression

This paper reviews the literature on sex and cultural differences in physical aggression and argues that only through understanding the interactions among evolutionary predispositions, hormonal influences, and social/situational factors can we possibly make sense of the patterns of human aggression that we see around us. Specifically, it is proposed that the process of natural selection has shaped hormonal responses in males that are sensitive to situations involving challenges to status and/or competition with other males, and that these hormonal changes are essential ingredients of the aggressiveness that occurs in these situations. Models of aggression that focus only on situational and cognitive/emotional triggers of aggressive behavior and attempt to understand human aggression without any reference to biology are destined to be incomplete at best.     

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.     

Primary Care and Clinical Psychology: Assessment Strategies in Medical Settings

There is ample evidence regarding medical-psychological comorbidity to consider clinical psychology as a viable component of health care services in medical settings. Psychologists can become valuable assets to primary care physicians who treat a high number of primary psychiatric cases as well as medical cases with secondary psychological symptoms. Psychologists who function in hospital-based clinics as well as affiliates with primary care (PC) offices can provide empirically supported assessment services that can make treatment more effective and efficient. Multiple studies indicate high prevalence rates of psychiatric patients in PC settings using various instruments. This paper reviews selected assessment tools that have established diagnostic validity and reliability that can be both strategic for patient care and useful to reinforce psychologist collaboration with primary care physicians (PCP).
