This study used the Multidimensional Personality Questionnaire (MPQ; A. Tellegen, in press) to identify personality-based subtypes of posttraumatic response. Cluster analyses of MPQs completed by combat veterans revealed subgroups that differed on measures relating to the externalization versus internalization of distress. The MPQ profile of the externalizing cluster was defined by low Constraint and Harmavoidance coupled with high Alienation and Aggression. Individuals in this cluster also had histories of delinquency and high rates of substance-related disorder. In comparison, the MPQ profile of the internalizing cluster was characterized by lower Positive Emotionality, Alienation, and Aggression and higher Constraint, and individuals in this cluster showed high rates of depressive disorder. These findings suggest that dispositions toward externalizing versus internalizing psychopathology may account for heterogeneity in the expression of posttraumatic responses, including patterns of comorbidity.

An examination of the relationships between health behaviors (preventive and risk-related), physician-diagnosed medical problems, role-functioning impairment because of physical morbidity, and post-traumatic stress disorder was conducted on a large cohort of consecutive treatment-seeking cases (N = 826) presenting to an outpatient Veterans Affairs post-traumatic stress disorder clinic. Results revealed that the sample rates of several medical conditions were markedly elevated when compared with general population rates for men of comparable age. The rates of smoking and other behavioral risk variables were greater than rates among men in the general population. Moreover, the majority of the sample did not engage in preventive health behaviors such as exercise and medical screening at levels consistent with health care guidelines. Physical role functioning indices of the SF-36 reveal greater role-functioning impairment because of physical morbidity in this psychiatric sample relative to the age adjusted general population norms. The health care implications of these data are discussed, as are areas for future research.

Planning is essential to creating safe schools and it is required by the Federal No Child Left Behind legislation (U.S. Department of Education, 2004) and implemented via district local education action plans. The implementation of these plans involves continuous monitoring and reevaluation of information pertinent to each campus. As such, this process is facilitated by the availability of measures that are simple to administer, inexpensive, and whose psychometric properties have been evaluated. The California School Climate and Safety Survey (CSCSS), originally developed by M.J. Furlong, R. Morrison, and S. Boles (1991), was specifically developed for these purposes. The CSCSS is a student self‐report questionnaire created to measure general school climate and personal safety‐related experiences. In this article, we present the results of an evaluation of the CSCSS including exploratory and confirmatory factor analyses. These analyses reduced the original CSCSS research version from 102 items to 54 items. The psychometric properties of this CSCSS‐SF (Short Form) are presented. © 2005 Wiley Periodicals, Inc.

This study examined 24-hr levels of ambulatory heart rate (HR) and blood pressure (BP) in 2 groups of male veterans: 19 with chronic posttraumatic stress disorder (PTSD) and 17 who never met criteria for PTSD. The relationships between diagnostic status, basal cardiovascular activity, and cardiovascular reactivity to stress were examined. Hierarchical linear modeling analyses revealed that the PTSD group had higher resting HR than the non-PTSD group. Moreover, the PTSD group showed greater BP reactivity during times of affective distress than the non-PTSD group. The health care implications of these findings are discussed, as are directions for future research.
