Trait impulsivity and callous-unemotional traits as predictors of inhibitory control and risky choices among high-risk adolescents

Trait impulsivity and callous-unemotional traits are associated with behavioural problems among high-risk adolescents. While both are known to influence behaviour, the nature of their expression in high-risk behaviours, particularly those related to inhibitory control, is not well understood. In the current, preliminary study, we examined whether and how these traits predicted deficits in behaviour driven by bottom-up, automatic versus deliberate, top-down inhibitory processes among high-risk adolescents. Two go/no-go task variants, emotional and non-emotional, were used to assess reactive response inhibition, and the Balloon Analogue Risk Task was used to assess the ability to resist deliberate risky choices. The results showed that the two types of self-reported trait measures were differentially associated with performance on the two types of behavioural inhibition tasks. Trait impulsivity predicted non-emotional inhibitory control whereas callous-unemotional traits predicted risky choices. The results also showed that the emotions task elicited slower reaction times and higher false alarm rates than did the letters task, and that participants had greater difficulty inhibiting responses to negatively than to positively valenced no-go stimuli. While preliminary, the results suggest that the interplay between trait impulsivity and callous-unemotional traits is an important determinant of inhibitory behaviour in this high-risk adolescents.     

REREADING STRATEGICALLY: THE INFLUENCES OF COMPREHENSION ABILITY AND A PRIOR READING ON THE MEMORY FOR EXPOSITORY TEXT

We examined the extent to which comprehenders read expository texts strategically after a prior reading and test. Sentence reading times and the memory for expository texts were examined across two readings. In Experiment 1, sentence reading times were facilitated during rereading to the extent that the information had been encoded from the initial reading. The memory data revealed that participants incorporated new information into their text representations. In particular, rereading improved the memory for causally important information. In Experiment 2, the pattern of results generalized to both good and poor readers except that the correlation between recall and importance was greater for the better readers. The results suggest that all participants reread strategically to some extent, but the better readers were able to use the incoming information to update their situation model.     

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.     

THE EVALUATION OF A SEXUAL ASSAULT SELF-DEFENSE AND RISK-REDUCTION PROGRAM FOR COLLEGE WOMEN: A PROSPECTIVE STUDY

The present study evaluated the efficacy of a sexual assault risk-reduction program that included a physical self-defense component for college women ( N = 500). Program group women significantly increased their protective behaviors over the 6-month follow-up period compared to the waiting-list control group. However, there were no significant differences between the two groups regarding rates of sexual victimization, assertive communication, or feelings of self-efficacy over the follow-up periods. Program group women who were victimized during the 3-month follow-up period evidenced less self-blame and greater offender blame for their assaults than control group women who were victimized following the program. Given that program women evidenced a greater awareness of sexual assault at the end of the study than control group women, the difficulty in addressing the impact of programming on rates of sexual victimization is discussed.     

Suicide across the Life Span: Pathways to Prevention

As reflected in a recent series of highly visible suicide awareness and prevention activities, the call for a comprehensive suicide prevention strategy has never been stronger, nor more unified. Using the framework provided by the transactional model of human development, the author illustrates the central implications that a developmental perspective has for suicide prevention, emphasizing the need to consider multiple pathways to prevention, to place renewed emphasis on prevention strategies that have their impact earlier in the life course and earlier in the course of mental disorder, and to collaborate with prevention specialists and advocates in related fields.
