Research ethics committees: a regional approach

Guidelines for Institutional Review Boards (IRBs) or research ethics committees exist at national and international levels. These guidelines are based on ethical principles and establish an internationally acceptable standard for the review and conduct of medical research. Having attained a multinational consensus about what these fundamental guidelines should be, IRBs are left to interpret the guidelines and devise their own means of implementing them. Individual and community values bear on the interpretation of the guidelines so different IRBs attain different levels of effectiveness. In the Caribbean and Pan American regions there are few IRBs. Obstacles to the establishment and function of IRBs are exacerbated in developing regions like these by differences in language, literacy, and local value systems; education, administrative expertise, facilities, and access to information are also limited. A regional IRB network might facilitate more uniform ethical review in developing countries, and simplify IRB procedures.

Spatial depth relationships in young children's drawings

Previous research suggests that young children do not attempt to represent depth relationships between objects in their drawings. The present study, however, showed that when both objects are visible and the children's attention is drawn to the depth relationship between them, most 5-, 6-, and 7-year-olds do attempt to portray this relationship.     

The Substance Abuse Counseling Needs of Women in the Criminal Justice System: A Needs Assessment Approach

The authors assessed the substance abuse counseling needs of women in the criminal justice system using interviews (n = 304) and surveys (n = 1,170). On the basis of the results, the authors call for gender‐specific treatment as well as family‐oriented support for women who are mothers.     

Striatal outcome processing in healthy aging

Functional MRI of young adults has implicated the striatum in the processing of rewarding and punishing events. To date, only two published experiments (Samanez-Larkin et al., 2007; Schott et al., 2007) have explored similar phenomena in older adults, with both studies emphasizing the anticipation of monetary outcomes. To better understand older participants’ striatal responses to delivered outcomes, we engaged 20 older adults and 13 younger adults in a card-guessing task that rewarded correct guesses with monetary gain and punished incorrect guesses with monetary loss. Overall, the older adults retained most of the typical features of the striatal response, so that activity in the caudate head showed reliable differentiation between rewards and punishments during the 6- to 9-sec postoutcome window. Comparison of the older and younger adults also pointed to some potential aging effects on outcome activity, including reductions in the magnitude and extent of striatal activation, and a trend for the older adults to show a decreased early punishment response. In sum, our data suggest that the signaling of outcome valence remains relatively stable into late adulthood, although more research is needed to understand some subtle changes that might occur across the life span.     

‘Faultless’ ignorance: Strengths and limitations of epistemic definitions of confabulation

There is no satisfactory account for the general phenomenon of confabulation, for the following reasons: (1) confabulation occurs in a number of pathological and non-pathological conditions; (2) impairments giving rise to confabulation are likely to have different neural bases; and (3) there is no unique theory explaining the aetiology of confabulations. An epistemic approach to defining confabulation could solve all of these issues, by focusing on the surface features of the phenomenon. However, existing epistemic accounts are unable to offer sufficient conditions for confabulation and tend to emphasise only its epistemic disadvantages. In this paper, we argue that a satisfactory epistemic account of confabulation should also acknowledge those features which are (potentially) epistemically advantageous. For example, confabulation may allow subjects to exercise some control over their own cognitive life which is instrumental to the construction or preservation of their sense of self.     

Effectiveness of a trauma/grief-focused group intervention: a qualitative study with war-exposed Bosnian adolescents

The effectiveness and impacts of a school-based, trauma/grief-focused group treatment program for war-exposed youth in Bosnia and Herzegovina were investigated using semistructured focus groups, conducted separately for students and their school counselor group leaders. Overall, students' and leaders' evaluations of the groups were generally positive. General themes of outcomes and impacts perceived by students and group leaders include: acquisition of coping skills and attitudes, willingness to advocate for peers, improved interpersonal relationships, negative impacts, general positive impacts, impacts in the schools, impacts on the group and logistics of the program, and broader impacts on the perception of mental health in the community. The broad positive impacts of this program suggest that trauma/grief-focused group treatment intervention programs targeting trauma-exposed youth may be effective on multiple levels with war-exposed youth and their communities.     

Robust dimensions of anxiety sensitivity: development and initial validation of the Anxiety Sensitivity Index-3

Accumulating evidence suggests that anxiety sensitivity (fear of arousal-related sensations) plays an important role in many clinical conditions, particularly anxiety disorders. Research has increasingly focused on how the basic dimensions of anxiety sensitivity are related to various forms of psychopathology. Such work has been hampered because the original measure--the Anxiety Sensitivity Index (ASI)--was not designed to be multidimensional. Subsequently developed multidimensional measures have unstable factor structures or measure only a subset of the most widely replicated factors. Therefore, the authors developed, via factor analysis of responses from U.S. and Canadian nonclinical participants (n=2,361), an 18-item measure, the ASI-3, which assesses the 3 factors best replicated in previous research: Physical, Cognitive, and Social Concerns. Factorial validity of the ASI-3 was supported by confirmatory factor analyses of 6 replication samples, including nonclinical samples from the United States and Canada, France, Mexico, the Netherlands, and Spain (n=4,494) and a clinical sample from the United States and Canada (n=390). The ASI-3 displayed generally good performance on other indices of reliability and validity, along with evidence of improved psychometric properties over the original ASI.
