Internal consistency (N = 172) and convergent validity (N = 73) of a Swedish translation of the Clinician-Administered PTSD Scale-Diagnostic Version (CAPS-DX) were evaluated with violence victims with posttraumatic stress disorder (PTSD). The CAPS-DX evidenced a promising internal consistency, and significant correlations (Pearson product-moment) with the PTSD Symptom Scale Self-Report version (PSS-SR) and the Impact of Event Scale-Revised (IES-R). Additionally, each subscale of the CAPS-DX (intrusion, avoidance/numbing, and arousal) was significantly correlated with the corresponding subscales of the PSS-SR and the IES-R. Results of the present study are discussed in the context of internal consistencies and convergent validity coefficients of the CAPS with other PTSD symptom measures in previous studies.

Posttraumatic stress disorder (PTSD) has been estimated to affect up to 18% of returning Operation Iraqi Freedom (OIF) veterans. Soldiers need to maintain constant vigilance to deal with unpredictable threats, and an unprecedented number of soldiers are surviving serious wounds. These risk factors are significant for development of PTSD; therefore, early and efficient intervention options must be identified and presented in a form acceptable to military personnel. This case report presents the results of treatment utilizing virtual reality exposure (VRE) therapy (virtual Iraq) to treat an OIF veteran with PTSD. Following brief VRE treatment, the veteran demonstrated improvement in PTSD symptoms as indicated by clinically and statistically significant changes in scores on the Clinician Administered PTSD Scale (CAPS; Blake et al., 1990) and the PTSD Symptom Scale Self-Report (PSS-SR; Foa, Riggs, Dancu, & Rothbaum, 1993). These results indicate preliminary promise for this treatment.

A novel capillary zone electrophoresis (CZE) method was developed for an improved separation and size characterization of pristine gold nanoparticles (AuNP) using uncoated fused-silica capillaries with UV-Vis detection at 520 nm. To avoid colloid aggregation and/or adsorption during runs, poly(sodium 4-styrenesulfonate) (PSS) was added (1%, w/v) in the running buffer (CAPS 10 mM, pH 11). This polyelectrolyte conferred an enhanced stabilization to AuNP, both steric and electrostatic, exalting at the same time their differences in electrophoretic mobility. Resolution was further and successfully improved through a stepwise field strength gradient by the application of 25 kV for the first 5 min and then 10 kV. Migration times varied linearly with particles diameters showing relative standard deviations better than 1% for daily experiments and 3% for interday experiments. A comparison with the size distribution obtained by transmission electron microscopy (TEM) allowed assessing that the electrophoretic profile can reasonably be considered as representative of the effective size heterogeneity of each colloid. Finally, the practical utility of the proposed method was demonstrated by measuring the core diameter of a gold colloid sample produced by chemical synthesis which was in good agreement with the value obtained by TEM measurements.
