Predictive and concurrent validity of the Suicidal Ideation Questionnaire among American Indian adolescents

Suicide is currently the second leading cause of death for ages 15–24 years; reports indicate that 6–8% of American teens have attempted suicide. Rates of suicide and suicide attempts are at least as high, if not higher, for American Indian adolescents and young adults. The Suicidal Ideation Questionnaire (Junior High School Version) (SIQ-JR) could be used to identify young people who may be at risk for attempting suicide, since this questionnaire focuses on suicidal ideation, a major risk factor for suicide attempt. However, little is known about the predictive validity of the SIQ-JR, particularly in American Indian adolescent populations. A suicide attempt cluster at an American Indian boarding school provided the unique opportunity to examine the performance of the SIQ-JR in a group of American Indian high school students who had taken the SIQ-JR approximately 2 months prior to the outbreak of attempts. The SIQ-JR proved to be an excellent predictor of future suicide attempts when compared to other measures of distress: anxiety, depression, and alcohol use. The SIQ-JR is an effective screener for suicide risk in this American Indian adolescent population.     

Category knowledge in Alzheimer's disease: normal organization and a general retrieval deficit.

Three hypotheses that could account for deficits in the retrieval of category information in Alzheimer's disease (AD) were evaluated: abnormal organization, class- or category-specific vulnerability, and limitation by general factors, such as decreased processing speed. Relative to 18 elderly control subjects, 18 patients with AD produced fewer items in a category fluency task and had longer reaction times in a category decision task. The pattern of performance across categories on both tasks was normal in the AD group: The same categories elicited the most (or fastest) responses in both the control group and the AD group. AD patients showed normal performance in ranking of category exemplars by typicality. There was no evidence for differential accessibility by category or by class of information (animate vs. inanimate). The authors conclude that a general factor or factors limit(s) retrievability equally across all categories.     

Perceived self-efficacy and language differences

The relationship between language differences and perceived self-efficacy was examined for two different classes (ns = 89 and 66) of a linguistically diverse nursing student population. Sherer, et al.'s General Self-efficacy Scale was factor analyzed, producing two factors (subscales) labeled Tendency to Avoid/Give Up and Tendency to Persist. Students who were nonprimary speakers of English were more likely to avoid difficult tasks or give up because they believed they would fail than those students who were primary speakers of English. There were no significant differences between the groups on Tendency to Persist. Also, students' class level in the program was not related to self-efficacy.     

Individual differences in trajectories of emotion regulation processes: the effects of maternal depressive symptomatology and children's physiological regulation

Trajectories of emotion regulation processes were examined in a community sample of 269 children across the ages of 4 to 7 using hierarchical linear modeling. Maternal depressive symptomatology (Symptom Checklist-90) and children's physiological reactivity (respiratory sinus arrhythmia [RSA]) and vagal regulation (Delta RSA) were explored as predictors of individual differences in trajectories of emotion regulation and negativity (mother-reported Emotion Regulation Checklist; A. M. Shields & D. Cicchetti, 1997). In addition, the authors explored whether children's physiological regulation would moderate the effect of maternal depressive symptomatology on children's emotion regulation trajectories. Results indicated that over time, emotion regulation increased whereas negativity decreased, though considerable individual variability in the pattern of change was observed. Greater maternal depressive symptomatology was associated with less steep emotion regulation trajectories. There was a significant Maternal Depressive Symptomatology x Baseline RSA x Age interaction predicting emotion regulation trajectories. Overall, it appears that the development of emotion regulation over time is compromised when mothers report greater depressive symptomatology. There is also evidence that children's capacity for physiological regulation can buffer some of the adverse consequences associated with maternal depressive symptomatology.     

Posttraumatic stress disorder symptoms, physiological reactivity, alcohol problems, and aggression among military veterans

This study examined the association between posttraumatic stress disorder (PTSD) symptomatology and aggressive behavior among a sample of male Vietnam veterans (N = 1,328). Results indicated that the hyperarousal PTSD symptom cluster evidenced the strongest positive association with aggression at the bivariate level when compared with the other PTSD symptom clusters. When the PTSD symptom clusters were examined together as predictors, hyperarousal symptoms evidenced a significant positive relationship with aggression, and avoidance/numbing symptoms were negatively associated with aggression. Examination of potential mediators indicated that hyperarousal symptoms were directly associated with aggression and indirectly related to aggression via alcohol problems. Reexperiencing symptoms were associated with aggression only indirectly and through their positive association with physiological reactivity and negative association with alcohol problems. Study results highlight the complexity of the relationship between PTSD symptoms and aggression, and suggest possible mechanisms explaining this association.     

Beliefs in Equality for Women and Men as Related to Economic Factors in Central and Eastern Europe and the United States

Do economic indicators predict the general level of support for gender equality? This question was investigated in a sample of countries in Central and Eastern Europe, a region that has been undergoing rapid economic changes since the early 1990s. In this overall sample of male and female college students from ten countries, including the United States as a comparison, the predicted association between stronger beliefs in gender role egalitarianism and positive economic factors was generally supported. Also, consistent with other research, women were more in support of gender equality than men were. There was no support for a predicted trend in less support for gender equality over the time period of the present study.     

Psychometric analyses of the Clinician-Administered PTSD Scale (CAPS)--Bosnian translation

Methods for assessing psychological distress in culturally diverse populations are not firmly established. This study was designed to examine the psychometric properties of the Bosnian translation of the Clinician-Administered PTSD Scale (CAPS; D. D. Blake, F. W. Weathers, L. M. Nagy, D. Kaloupek, G. Klauminzer, D. Charney, et al., 1995) in a Bosnian refugee sample. The authors interviewed 115 help-seeking Bosnian refugees with the CAPS-Bosnian translation to examine its internal consistency and convergent validity, and to provide an assessment of its factor structure. This study demonstrated optimal fit with a 2-factor model of posttraumatic stress disorder (PTSD); the authors also found high reliability with a coefficient alpha of 0.92 and strong convergent validity with instruments measuring depression, anxiety, and levels of psychosocial functioning. Future directions for the assessment of PTSD in cross-cultural populations are discussed.     

University socialization and the acceptance of anti‐egalitarian ideology: The underlying role of extrinsic life goals

Past research suggests that students in social science often become more egalitarian while students in business and economics show a trend in the opposite direction. Using a cross‐sectional study in which we compared first and third year students from different academic environments, we wanted to explore these issues and to test whether life goals may account for potential ideological differences among them. Psychology and economics students at first and third year of their respective academic group completed both the Aspiration index and social dominance orientation scale. Consistent with the socialization hypothesis, economics students reported higher levels of social dominance orientation than psychology students but only at the third year of study. A similar pattern of results was observed for extrinsic life goals (but no differences were found for intrinsic life goals). Importantly, the interaction between academic year and academic major on social dominance orientation was mediated by the measure of extrinsic life goals.     

Constructing the Conditions of and Environments for Interdisciplinary Research on Perception and Action

This paper suggests ways in which art processes may contribute to the interdisciplinary study of perception and action and the relationships between body, person, and environment. Artists-turned-architects Arakawa and Gins serve as the most advanced example of an interdisciplinary research project in terms of coordinating material processes with contemporary findings, methods, and orientations from across the arts, humanities, and hard and soft sciences. In the first section of the paper, I discuss Arakawa and Gins's Reversible Destiny Lofts at Mitaka as an example of their procedural approach to long-term sustainable experimental environments. In the second section, the tactics through which Arakawa and Gins have repositioned art for the nonart purposes and common research goals are posited. Finally, I briefly outline the disciplinary positions and research values needed in order to move toward a more inclusive and interdisciplinary research practice.
