Risk Factors for Adolescent Suicide and Suicidal Behavior: Mental and Substance Abuse Disorders,Family Environmental Factors,and Life Stress

This review focuses on psychopathologic risk factors for adolescent suicide and suicidal behavior, namely, affective, disruptive, substance abuse, psychotic, and personality disorders. The interaction of psychopathology with age and gender is discussed. The role of family environmental risk factors and stress events in suicide and suicidal behavior, both alone, and in interaction with psychopathology are reviewed. Research reviewed will include psychological; autopsy studies, longitudinal studies examining predictors of suicide, and epidemiologic studies of suicide attempts.     

Sexual Orientation in Adolescents Who Commit Suicide

It has been suggested that there is a strong relationship between suicidal behavior and homosexuality in adolescence. It has been further suggested that it is due to the stigmatization and feelings of isolation that are experienced by many gay adolescents. Much of the literature that has given support to these hypotheses has been conducted on uncontrolled nonrepresentative samples and its generalizability is open to question. An opportunity to examine the relationship in an unselected sample arose in a case control, psychological autopsy study of 120 of 170 consecutive suicides under age 20 and 147 community age, sex, and ethnic matched controls living in the Greater New York City area. Homosexuality was defined as having had homosexual experiences or having declared a homosexual orientation. Three teenagers and no controls met these criteria. The difference was not significant. The circumstances of death were examined and are described. In no instance did suicide directly follow an episode of stigmatization. All three suicides had evidence of significant psychiatric disorder before death. In spite of opportunities for biased reporting, it is concluded that this study finds no evidence that suicide is a common characteristic of gay youth, or that when suicide does occur among gay teenagers, that it is a direct consequence of stigmatization or lack of support.     

Research in Adolescent Suicide: Implications for Training,Service Delivery,and Public Policy

Four domains of research in adolescent suicide are reviewed: (1) the role of psychopathology, (2) family history of psychopathology, (3) mental health treatments, and (4) firearms in the home. Based on the extant literature, recommendations are made for changes in training, service delivery, and public policy. Among the recommendations for training professionals are: an emphasis on diagnostic proficiency, skill and attentiveness in the assessment of the entire family unit, and assessment of the availability of firearms in the home. With respect to changes in service delivery, we recommend treatment of the entire family system, and treatment of psychiatric and substance abuse problems in the same setting, and we show the need for a continuum of intensity of care from inpatient to outpatient. With respect to policy changes, we recommended parity of mental and physical health insurance coverage, screening for psychiatrically at-risk youngsters in schools and physicians' offices, providing funding to support a continuum of care between inpatient and outpatient, and gun control laws to restrict access to handguns. We believe that these changes can result in a substantial reduction in the adolescent suicide rate.     

Age-related increase in top-down activation of visual features

Previous research suggests that, during visual search and discrimination tasks, older adults place greater emphasis than younger adults on top-down attention. This experiment investigated the relative contribution of target activation and distractor inhibition to this age difference. Younger and older adults performed a singleton discrimination task in which either an E or an R target (colour singleton) was present among distractor letters. Relative to a baseline condition in which the colours of the targets and distractors remained constant, an age-related slowing of performance was evident when either the colour of the target or that of the distractors varied across trials. The age-related slowing was more pronounced in response to target colour variation, suggesting that older adults place relatively greater emphasis on the top-down activation of target features.     

Facial Affect Recognition and Psychopathy: A Signal Detection Theory Perspective

Though emotional processing deficits are often conceptualized as a core feature of psychopathy, the common assessment of these deficits using the percentage correct (or hit rate) on affect recognition tasks may not provide a full or accurate picture of facial affect recognition in psychopathic individuals. Signal detection theory (SDT) provides a more informative statistical approach by providing independent measures of perceptual sensitivity (d’) and willingness to report perceiving a signal or response criterion (c). The current study employed signal detection methods to test the predictions of the integrated emotion systems and hostile attribution bias perspectives, two theoretical perspectives that make specific predictions regarding facial affect recognition. These perspectives were tested in a sample of 280 adult male incarcerated offenders who were assessed for psychopathy using the Psychopathy Checklist-Revised and who completed a novel test of facial affect recognition presenting 324 digital morphs of faces reflecting systematic combinations of pixels from neutral and affective face images (displaying six different types of emotion) as expressed by four different actors. The findings were generally not consistent with either of these perspectives. Psychopathy was negatively associated with d` for anger. Results also indicated an effect of psychopathy on response criterion for fear and effects of psychopathy on response criterion for anger and surprise that were evident only for some actors. The implications of these findings are considered through the lenses of several theoretical perspectives, and theoretical and methodological limitations of the current study are considered.

     

Divergent effects of different positive emotions on moral judgment

Positive emotions are often treated as relatively similar in their cognitive-behavioral effects, and as having unambiguously beneficial consequences. For example, Valdesolo and DeSteno (2006) reported that a humorous video made people more prone to choose a utilitarian solution to a moral dilemma. They attributed this finding to increased positive affect. To determine whether such results actually stem in general from positive affect or from other more specific properties of humor, we conducted an experiment with moral dilemmas presented during an interleaved emotion-induction procedure involving mirth and another positive emotion, elevation. Mirth increased permissiveness for deontological violations, whereas elevation had the opposite effect. Furthermore, affective valence had no apparent independent influence on these judgments. Our results suggest that mirth and elevation have distinct cognitive consequences whose properties reflect their respective social functions, not their shared positive valence.     

God and Country: The Partisan Psychology of the Presidency,Religion, and Nation

Overt love of God and country have seemingly been prerequisites to be president in the United States in recent decades, if not always. Indeed, the 2008 presidential race was replete with campaign messages showcasing such perspectives—that Barack Obama and John McCain were religiously faithful and deeply patriotic. Scholarship demonstrates the potential political power of explicit appeals to America and Christianity; however, little research has examined (a) citizens' perceptions of candidates' ties to faith and nation and (b) how these impressions may be related to electoral attitudes and intended vote. We address this gap, measuring both explicit and implicit indicators of the Christian‐ness and American‐ness of Obama and McCain. We expected and found that both explicit and—in a final‐entry regression position—implicit perceptions of these traits related to voters' overall candidate attitudes and intended vote choice and that they were connected significantly more strongly for our sample of self‐described Republicans than Democrats. Results illuminate these partisan differences and raise questions about their implications for U.S. presidential politics in years to come.
