A Pilot Randomized Controlled Trial of the Alliance Project Gatekeeper Training for Suicide Prevention.

Gatekeeper trainings are an approach intended to increase help seeking for suicide prevention. However, little is known of gatekeeper training's function in increasing gatekeeper intent to intervene with those in distress. The current study utilized the theory of planned behavior as a guide to predict gatekeeper's intention to intervene over a six-month period in a pilot randomized controlled trial of the Alliance Project gatekeeper training. Results suggested that the Alliance Project, predicted the growth curve of trainees' intention to intervene better than a control training from pretest through six months. Attitudes toward completing gatekeeper behaviors and perceived behavioral control over gatekeeper behaviors approached significance in a less parsimonious model. These findings suggest the Alliance Project produces changes in gatekeeper's intent to intervene through three months' time.

The effect of health insurance coverage and the doctor-patient relationship on health care utilization in high poverty neighborhoods.

African Americans have higher rates of mortality than whites who are the same age and sex. We hypothesize that in low socioeconomic status neighborhoods, having health insurance coverage and a regular health care provider increases the likelihood of receiving diagnostic tests for cardiovascular disease and diabetes. We use data from a random two-stage cluster sample of 230 adults living in high poverty census tracts to examine the effects of insurance coverage and having a regular doctor on the likelihood receiving diagnostic tests for high cholesterol, high blood sugar, and blood pressure. We find that health insurance coverage increases the odds of having a regular health care provider (p < 0.05) and of receiving the diagnostic tests (p < 0.05). Having a regular doctor mediates the effect of insurance coverage on the likelihood of receiving the tests, especially when the participant can report the physician's name.

Grassland fires may favor native over introduced plants by reducing pathogen loads.

Grasslands have been lost and degraded in the United States since Euro-American settlement due to agriculture, development, introduced invasive species, and changes in fire regimes. Fire is frequently used in prairie restoration to control invasion by trees and shrubs, but may have additional consequences. For example, fire might reduce damage by herbivore and pathogen enemies by eliminating litter, which harbors eggs and spores. Less obviously, fire might influence enemy loads differently for native and introduced plant hosts. We used a controlled burn in a Willamette Valley (Oregon) prairie to examine these questions. We expected that, without fire, introduced host plants should have less damage than native host plants because the introduced species are likely to have left many of their enemies behind when they were transported to their new range (the enemy release hypothesis, or ERH). If the ERH holds, then fire, which should temporarily reduce enemies on all species, should give an advantage to the natives because they should see greater total reduction in damage by enemies. Prior to the burn, we censused herbivore and pathogen attack on eight plant species (five of nonnative origin: Bromus hordaceous, Cynosuros echinatus, Galium divaricatum, Schedonorus arundinaceus (= Festuca arundinacea), and Sherardia arvensis; and three natives: Danthonia californica, Epilobium minutum, and Lomatium nudicale). The same plots were monitored for two years post-fire. Prior to the burn, native plants had more kinds of damage and more pathogen damage than introduced plants, consistent with the ERH. Fire reduced pathogen damage relative to the controls more for the native than the introduced species, but the effects on herbivory were negligible. Pathogen attack was correlated with plant reproductive fitness, whereas herbivory was not. These results suggest that fire may be useful for promoting some native plants in prairies due to its negative effects on their pathogens.

Investigating health disparities through community-based participatory research: lessons learned from a process evaluation.

This article describes one university's efforts to partner with a local agency (the "Coalition") within a disadvantaged, predominantly African American neighborhood, to assist them with studying their community's health disparities and health care access. The final, mutually agreed-upon plan used a community-based participatory research approach, wherein university researchers prepared neighborhood volunteers and Coalition members to conduct face-to-face interviews with residents about their health and health care access. Subsequently, the Coalition surveyed 138 residents, and the agency now possesses extensive data about the nature and extent of health problems in their community. Lessons learned from these experiences are offered.

Psychometric properties of a suicide screen for adjudicated youth in residential care.

There is a need to efficiently and effectively screen adjudicated youth residing within the juvenile justice system for suicide proneness. Accordingly, in the current study, the psychometric properties of the Life Attitude Schedule: Short Form (LAS:S), a 24-item risk assessment for suicide proneness, were assessed using data from adjudicated youth residing in an alternative sentencing facility (n = 130). As predicted, statistically significant correlations were obtained between total LAS:S suicide proneness scores and reports of recent suicide ideation and hopelessness. Contrary to expectation, the previously reported 2-factor model for the LAS:S, with Factor 1 representing physical unhealthiness and Factor 2 representing psychological death, poorly fit the data. In adjudicated youth, we found that a single factor model derived from the 4 LAS:S subscales produced a better fit to the data than the 2-factor model. The death-related, self-related, injury-related, and negative health-related behaviors contained on the LAS:S shared common variance in these youth. A clinical implication is that practitioners can effectively use the total LAS:S score when screening adjudicated youth for suicide proneness.

Hurricane Katrina and mental health: a research note on Mississippi Gulf Coast residents.

Katrina was the most devastating and deadliest hurricane in recent U.S. history. The storm was particularly destructive for residents of the Mississippi Gulf Coast where sustained winds of 135 mph and a storm surge of 32 feet literally obliterated the built and modified environments. Limited research exists on the chronic (32 months) mental health impacts of survivors in this geographical area. Random-digit dialing telephone surveys were administered in Harrison and Hancock counties (Mississippi) in April and May 2008 and data were collected on a number of mental health outcomes. The results of the calculation of Oridinary Least Squares (OLS) regression models revealed that females, African Americans, and less-educated residents manifested the most severe mental health impacts. Most important, consistent findings for depression and Katrina-related psychological stress indicate that residents who were separated from family members, had maximum residential damage, and suffered severe financial problems remained significantly impacted 32 months after Katrina's landfall. A secondary stressor, in the form of having applications to the Mississippi State Grant Program denied or not processed also predicted personal depression. The implications of these findings are discussed.
