Positive and Negative Expectations of Hopelessness as Longitudinal Predictors of Depression,Suicidal Ideation,and Suicidal Behavior in High‐Risk Adolescents

The relationship between hopelessness and depression in predicting suicide‐related outcomes varies based on the anticipation of positive versus negative events. In this prospective study of adolescents at elevated risk for suicide, we used two Beck Hopelessness Scale subscales to assess the impact of positive and negative expectations in predicting depression, suicidal ideation, and suicidal behavior over a 2‐ to 4‐year period. In multivariate regressions controlling for depression, suicidal ideation, and negative‐expectation hopelessness, positive‐expectation hopelessness was the only significant predictor of depressive symptoms and suicidal behavior. Clinical interventions may benefit from bolstering positive expectations and building optimism.     

A Trait‐Interpersonal Analysis of Suicide Proneness Among Lesbian,Gay, and Bisexual Community Members

Suicide remains a concerning issue for lesbian, gay, and bisexual (LGB) persons. The integrated effects of five‐factor model personality traits and interpersonal‐psychological theory of suicide (IPTS) constructs on suicide proneness in a community sample of 336 LGB adults were examined. Results supported a model inclusive of all five‐factor model domains predicting IPTS constructs leading to suicide proneness. Effects of neuroticism and extraversion were both mediated by perceived burdensomeness and thwarted belongingness. Thwarted belongingness mediated the effect of agreeableness on suicide proneness. Identified mediation pathways build on existing trait‐interpersonal theory and may inform clinical services for sexual minority persons.     

Investigating Correlates of Suicide Among Male Youth: Questioning the Close Affinity Between Suicide Attempts and Deaths

This study was based on a sample of male high school students who completed National Longitudinal Adolescent Health Surveys in 1994, 1995, and 2001. We studied these students prospectively, comparing those who later died by suicide (n = 21) with those who were still living (n = 10,101). We employed chi‐square and analysis of variance tests for statistical significance between suicide decedents and living respondents. Results showed suicide decedents were more likely to have experienced the suicide loss of another family member, to have been expelled from school, to have engaged in more delinquent actions including fighting, and to have greater involvement with the criminal justice system. Although one might have expected suicide casualties to have exhibited a greater amount of suicidal thoughts, attempts, and higher incidences of suicidality among their friends, our analyses did not find that these factors were associated with actual suicides. Should these findings be replicated, this would point to a need to refine youth suicide risk assessments. Collecting life histories, as well as identifying patterns of delinquency and fighting, may serve as more potentially fruitful means for assessing genuine suicide risk than some traditional risk assessment methods.z     

Why Speciesism is Wrong: A Response to Kagan

In Animal Liberation I argued that we commonly ignore or discount the interests of sentient members of other species merely because they are not human, and that this bias in favour of members of our own species is, in important respects, parallel to the biases that lie behind racism and sexism. Shelly Kagan, in ‘What's Wrong With Speciesism’ misconstrues this argument, as well as the principle of equal consideration of interests, which I offer as an alternative to speciesism. Kagan also offers, as an alternative explanation of, and possible justification for, our discounting the interests of nonhuman animals, the suggestion that your interests count more if you are a member of a species whose typical adult members are persons. Although this view is not a form of speciesism, Kagan seems not to be aware of the fact that it is a view commonly defended by advocates of natural law ethics, on which there is already an extensive critical literature.

Temporal binding, binocular rivalry, and consciousness.

Cognitive functions like perception, memory, language, or consciousness are based on highly parallel and distributed information processing by the brain. One of the major unresolved questions is how information can be integrated and how coherent representational states can be established in the distributed neuronal systems subserving these functions. It has been suggested that this so-called "binding problem" may be solved in the temporal domain. The hypothesis is that synchronization of neuronal discharges can serve for the integration of distributed neurons into cell assemblies and that this process may underlie the selection of perceptually and behaviorally relevant information. As we intend to show here, this temporal binding hypothesis has implications for the search of the neural correlate of consciousness. We review experimental results, mainly obtained in the visual system, which support the notion of temporal binding. In particular, we discuss recent experiments on the neural mechanisms of binocular rivalry which suggest that appropriate synchronization among cortical neurons may be one of the necessary conditions for the buildup of perceptual states and awareness of sensory stimuli.     

The Application of Cognitive Therapy for Command Hallucinations

It has become increasingly recognized that cognitive therapy (CT) is an effective treatment for the positive symptoms of schizophrenia yet there are few cognitive therapists in North America who are specialized to work with this patient population. There is a need for further dissemination of CT for schizophrenia in order to increase its availability. A first step in dissemination is to become familiar with the cognitive theory and therapy model, as applied to schizophrenia. The purpose of the present paper is to demonstrate the applicability of CT for psychosis, using the example of command hallucinations. First, we summarize the cognitive theory of command hallucinations and present the stages of CT, using the example of “Joe,” a 24-year-old male with schizophrenia. The paper concludes with practical suggestions of how to enhance the effectiveness of CT for command hallucinations.
