Research has consistently shown that drinking to alleviate negative emotional states predicts alcohol use and relapse among clients with co-occurring disorders including depressive and posttraumatic stress disorders. However, studies examining the mediating role of drinking motives in persons with severe mental illness (SMI) are few. The current survey of 116 community mental health clients (51.7% men; 47.4% women) diagnosed with either a schizophrenia spectrum disorder (41, 35.3%) or major mood disorder (75, 64.7%) tested the hypothesis that convivial drinking and drinking to cope with negative emotions would mediate posttraumatic stress symptoms (PSS-I) and alcohol consumption (QF). A series of path models revealed that convivial drinking fully mediated hyper-arousal symptoms and alcohol consumption, and negative coping fully mediated total posttraumatic stress symptoms, avoidance and hyper-arousal symptoms and alcohol consumption. The results support an emotional distress reduction model of alcohol use in people with severe mental illness, and highlight the need to assess specific drinking motives and target them in cognitive-behavioral treatment approaches. The cross sectional design employed limits cause-effect inferences regarding mediation, and highlights the need for longitudinal designs to sort out causal pathways among symptoms, drinking motives and alcohol consumption in clients with SMI. © 2011 Elsevier Ltd.

This study presents a single-Doppler radar analysis combined with cloud photography of the LaGrange, Wyoming, tornado on 5 June 2009 in an attempt to relate the radar-observed hook echo, weak-echo hole (WEH), and rotational couplet to the visual characteristics of the tornado. The tornado was rated EF2. The circulation at low levels went through two intensification periods based on azimuthal shear measurements. The first intensification was followed by the appearance of a brief funnel cloud. The second intensification was coincident with the appearance of a second funnel cloud that remained in contact with the ground until the tornado dissipated. A deep WEH rapidly formed within the hook echo after damaging wind was identified at the ground and before the appearance of a funnel cloud. The echo pattern through the hook echo on 5 June undergoes a dramatic evolution. Initially, the minimum radar reflectivities are near the surface (15 dBZ) and theWEH does not suggest a tapered structure near the ground. Subsequently, higher reflectivities appear at low levels when the funnel cloud makes contact with the ground. During one analysis time, the increase of the echo within the WEH at low levels results in a couplet of high/low radar reflectivity in the vertical. This increase in echo at low levels is believed to be associated with lofted debris although none was visibly apparent until the last analysis time. The WEH was nominally wider than the visible funnel cloud. The dataset provides the first detailed analysis of the double-ring structure within a hook echo that has been reported in several studies. The inner high-reflectivity region is believed to be a result of lofted debris. At higher-elevation angles, a small secondary WEH formed within the first WEH when debris was lofted and centrifuged. A feature noted in past studies showing high-resolution vertical cross sections of single-Doppler velocity normal to the radar beam is an intense rotational couplet of negative and positive values in the lowest few hundred meters. This couplet was also evident in the analysis of the LaGrange tornado. The couplet was asymmetric with stronger negative velocities owing to the motion of the tornado toward the radar. The damaging wind observed by radar extended well beyond the condensation funnel in the lowest few hundred meters. However, another couplet indicating strong rotation was also noted aloft in a number of volume scans. The decrease in rotational velocities between the low-and upper-level couplets may be related to air being forced radially outward from the tornado center at a location above the intense inflow. © 2011 American Meteorological Society.

A ground-based velocity track display (GBVTD) analysis of the LaGrange, Wyoming, tornado on 5 June 2009 during the Second Verification of the Origins of Rotation in Tornadoes Experiment (VORTEX2) is photogrammetrically combined with a series of pictures of the funnel cloud. This analysis reveals the relationship between the vertical velocity, radial and tangential velocities, perturbation pressure, vertical vorticity, and angular momentum with the visual features of the tornado. An intense axial downdraft was evident and was supported by a downward-directed perturbation pressure gradient. The radial inflow at low levels was weak and difficult to retrieve owing to a combination of centrifuging of hydrometeors/debris in the intense circulation and the inability of the radar beam to fully resolve the flow. The tornado was weakening during the analysis period, which was supported by angular momentum being advected out of the tornado. The availability of a dual-Doppler wind synthesis for this tornadic event provided a unique opportunity to assess the assumptions in the GBVTD methodology. The analysis suggests that the simplified GBVTD equations that have been applied in past studies of tornadoes are not appropriate in the present case. The most accurate retrieval of the radial velocities requires that a higher-order term that is typically neglected be retained. A quantitative assessment of the impact of centrifuging of hydrometeors on the synthesized wind field was attempted. The results suggest that the radial and vertical velocity profile near and within the tornado core can be significantly altered for tornadoes (EF2) that are accompanied by a small radius of maximum wind and relatively weaker low-level inflow. ©2012 American Meteorological Society.

Data from interviews with 276 community mental health clients diagnosed with a severe mental illness were used to examine the association between clients' subjective distress from sudden loss of a close friend or loved one and PTSD symptoms. Over three-quarters of these clients reported sudden losses in their lives, and regression analysis showed that distress related to sudden losses accounted for significant and unique variance in PTSD symptoms when all other sources of traumatic distress were controlled. Practitioners should routinely assess interpersonal losses among clients with SMI and offer brief interventions specifically aimed at helping clients cope with such losses. © 2011 Springer Science+Business Media, LLC.

A compelling body of literature suggests that negative appraisal may be associated with adverse reactions to traumatic stress. However, very few studies have examined how appraisal influences posttraumatic adaptation in people with serious mental illness (SMI) despite evidence of disproportionately high prevalence rates of trauma exposure and Posttraumatic Stress Disorder (PTSD) in this population. The purpose of this article is to provide a critical analysis of the theoretical and empirical literature on cognitive appraisal and psychological adaptation to traumatic stress with a specific focus on individuals diagnosed with SMI. It will be argued that appraisal is a key correlate that may partially account for higher rates of PTSD in people diagnosed with major mood and schizophrenia-spectrum disorders, meriting special consideration for future research. © The Author(s) 2011.
