Hope as a Predictor of Interpersonal Suicide Risk

The current study hypothesized that (1) hope would negatively predict burdensomeness, thwarted belongingness, and acquired capability to enact lethal injury; (2) hope would negatively predict suicidal ideation; and (3) the interpersonal suicide risk factors would predict suicidal ideation. Results indicated that hope negatively predicted burdensomeness and thwarted belongingness, but positively predicted acquired capability to enact suicide. Contrary to our second hypothesis, hope did not predict suicidal ideation, but interpersonal risk factors for suicide predicted suicidal ideation. Results are discussed in terms of implications for hope theory and Joiner's (2005) interpersonal risk factors for suicide, and for clinical practice.     

A longitudinal study of pain sensitivity and blood pressure in adolescent boys: results from a 5-year follow-up.

A growing literature has observed a significant reduction in pain sensitivity among hypertensive animals and humans. It is uncertain whether a reduced sensitivity to pain can be observed in nonnotensive individuals who go on to develop high blood pressure. Blood pressure (BP) was reassessed in one hundred fifteen 19-year-old boys initially tested at age 14, when they were also presented with a pain stimulus (mechanical finger pressure). Hierarchical regression analyses indicated that information regarding pain tolerance improved prediction of changes in systolic and diastolic blood pressure beyond that afforded by differences in BP at age 14, parental history of hypertension, and body mass index. These analyses suggest that pain sensitivity may be associated with physiological processes involved in the development of sustained high blood pressure.     

When a Lot of Knowledge Is a Dangerous Thing The Debilitating Effects of Plan Complexity on Verbal Fluency

Three experiments examined the relationships among plan complexity, access to planned actions, and verbal fluency while pursuing a persuasion goal. Consistent with theoretical expectations, complex planners were less fluent than less complex planners under high access conditions. Persons whose access was raised were less fluent than those whose access was not raised. A second experiment showed that reduced fluency was not induced by lowering of self-confidence. The third experiment replicated the findings of the second experiment and demonstrated that the questioning procedure used to raise access in the first two experiments produced increases in plan complexity as suggested by theory. These findings are discussed in terms of their implications for the study of strategic communication.
