Four studies on how past and current suicidality relate even when "everything but the kitchen sink" is covaried

T. E. Joiner's (2004, in press) theory of suicidal behavior suggests that past suicidal behavior plays an important role in future suicidality. However, the mechanism by which this risk is transferred and the causal implications have not been well studied. The current study provides evaluation of the nature and limits of this relationship across 4 populations, with varying degrees of suicidal behavior. Across settings, age groups, and impairment levels, the association between past suicidal behavior and current suicidal symptoms held, even when controlling for strong covariates like hopelessness and symptoms of various Axis I and II syndromes. Results provide additional support for the importance of past suicidality as a substantive risk factor for later suicidal behavior.     

Inertial eigenvalues, rod density, and rod diameter in length perception by dynamic touch

Four experiments addressed the relevance of the eigenvaluesI _k of the inertia tensor for perceiving length by dynamic touch. Experiments 1–2 focused on the consequences of limiting variation in the minimum eigenvalueI ₃. Both revealed that perceived length is a function ofI _k . Whether the contribution ofI ₃ is detected, however, depends on the range of values that characterize a particular object set. Experiments 3–4 considered the relationship between an independent index of a rod’s diameter, which does not affectI _k , and actual manipulation of a rod’s diameter, which does affectI _k . Whereas the former appeared as satisfaction of implicit instructions to alter reports of perceived length, the latter entailed actual differences in perceived length in accordance withI _k . Results are discussed with respect to the links among actual length, perceived length, andI _k , as well as, in particular, how these links guarantee that perceived length is in the range of actual lengths.     

The Air Pollution Experience and Physical Aggression1

Sixty undergraduate males delivered electric shocks to a confederate as punishment for making errors on a learning task. Half did so after being exposed to an aggressive model, whereas the other half did so without being exposed. Shocks were delivered from a room whose atmosphere was either unpolluted or contaminated by a moderately unpleasant odor (ethyl mercoptan) or an extremely obnoxious stench (ammonium sulfide). As hypothesized, the moderately unpleasant pollutant facilitated higher levels of aggression than either the extremely obnoxious one or the absence of pollution. However, contrary to a second hypothesis, pollution facilitated aggression only in the model's absence. The confirmation of the first hypothesis was interpreted as supporting and extending the affect-aggression model from heat research. It was speculated that disconfirmation of the second hypothesis resulted either from a ceiling effect or from malodor distracting attention away from the aggressive cues of the model. The methodological, theoretical, and applied implications of research on air pollution were discussed.     

Combining whole-school and targeted programs for the reduction of bullying victimization: A randomized,effectiveness trial

Despite the extensive evaluation of school-based interventions for bullying, victimization remains a significant problem in schools. Bullying victimization is significantly predicted by contextual (school-related) factors. As a consequence whole-school programs have been commonly used to prevent and reduce bullying victimization. Evidence also points to individual risk factors (such as emotional distress) in predicting victimization, yet programs to prevent bullying victimization by changing these individual risks are far less developed. Few studies have approximated “real-world” implementation conditions in their trials. The current effectiveness trial evaluated the combination of a whole-school program designed to prevent bullying perpetration and victimization together with a targeted intervention for at-risk students, teaching them individual and dyadic strategies to reduce their anxiety and manage victimization, allowing schools some latitude to implement programs as they typically would. Students from Grades 3 and 4 (N = 8,732) across 135 schools were randomly assigned to one of four conditions: combined intervention; whole-school intervention only; individual intervention only; and care as usual. Victimization decreased significantly and similarly across all four conditions at 12 and 24 months following baseline. Similar reductions and failure to discriminate conditions were found on other key constructs: anxiety; bullying perpetration; and depression. Possible reasons for the failure to demonstrate victimization prevention differences and lessons learned from this large, effectiveness trial are considered.     

The Role of Network Support and Interference in Women's Perception of Romantic,Friend, and Parental Relationships

This study examined the association between support/interference from the best friend and closest parent to women's (a) satisfaction with the parent–daughter relationship, (b) satisfaction with the friendship, and (c) love for the romantic partner. The respondents (n = 162 females; 84% Caucasian, 1% Asian American, 10% Hispanic, 4% African American, and 1% Multiracial) completed a questionnaire packet to assess each of the factors. Results revealed that romantic love was unrelated to friend support, friend interference, or parental interference, but positively related to parental support. Parent support was a significant correlate of parent satisfaction, and a similar pattern emerged between friend support/friendship satisfaction. Further, best friend support moderated the relationship between friend interference and friendship satisfaction, such that interference was negatively related to satisfaction in low support conditions. Overall, the results suggested that network reactions to romance played a limited role in romantic affection, but were more strongly associated with network satisfaction.     

Religious Perspectives on the Use of Psychopharmaceuticals as an Enhancement Technology

The use of psychopharmaceuticals as an enhancement technology has been the focus of attention in the bioethics literature. However, there has been little examination of the challenges that this practice creates for religious traditions that place importance on questions of being, authenticity, and identity. We asked expert commentators from six major world religions to consider the issues raised by psychopharmaceuticals as an enhancement technology. These commentaries reveal that in assessing the appropriate place of medical therapies, religious traditions, like secular perspectives, rely upon ideas about health and disease and about normal human behavior. But unlike secular perspectives, faith traditions explicitly concern themselves with ways in which medicine should or should not be used to live a “good life”.     

Relating Kindergarten Attention to Subsequent Developmental Pathways of Classroom Engagement in Elementary School

We examine the relationship between children's kindergarten attention skills and developmental patterns of classroom engagement throughout elementary school in disadvantaged urban neighbourhoods. Kindergarten measures include teacher ratings of classroom behavior, direct assessments of number knowledge and receptive vocabulary, and parent-reported family characteristics. From grades 1 through 6, teachers also rated children's classroom engagement. Semi-parametric mixture modeling generated three distinct trajectories of classroom engagement (n?=?1369, 50% boys). Higher levels of kindergarten attention were proportionately associated with greater chances of belonging to better classroom engagement trajectories compared to the lowest classroom engagement trajectory. In fact, improvements in kindergarten attention reliably increased the likelihood of belonging to more productive classroom engagement trajectories throughout elementary school, above and beyond confounding child and family factors. Measuring the development of classroom productivity is pertinent because such dispositions represent precursors to mental health, task-orientation, and persistence in high school and workplace behavior in adulthood.     

Measurement issues in health-related quality of life: Challenges for health psychology

Abstract

Quality of life assessment is a central element of clinical trials and related forms of evaluative research. Early efforts to establish appropriate methods of measuring quality of life drew on psychometric principles and emphasised the need for validated measures. However, it is increasingly clear that, whilst still a central requirement of quality of life measures, validity needs to be emphasised alongside a number of other essential properties that have become clearer as the field has developed. Moreover formal psychometric methodology has to be adapted to take account of the specific needs of evaluative research. Research is beginning to develop more appropriate methods of outcome assessment in this area. Further lines of research are suggested to examine psychometric with other approaches to measurement of health-related quality of life.     

The Establishment of Core Competencies for Canadian Genetic Counsellors: Validation of Practice Based Competencies

Numerous groups of health professionals have undertaken the task of defining core competencies for their profession. The goal of establishing core competencies is to have a defined standard for such professional needs as practice guidelines, training curricula, certification, continuing competency and re-entry to practice. In 2006, the Canadian Association of Genetic Counsellors (CAGC) recognized the need for uniform practice standards for the profession in Canada, given the rapid progress of genetic knowledge and technologies, the expanding practice of genetic counsellors and the increasing demand for services. We report here the process by which the CAGC Practice Based Competencies were developed and then validated via two survey cycles, the first within the CAGC membership, and the second with feedback from external stakeholders. These competencies were formally approved in 2012 and describe the integrated skills, attitudes and judgment that genetic counsellors in Canada require in order to perform the services and duties that fall within the practice of the profession responsibly, safely, effectively and ethically.
