Posttraumatic stress disorder (PTSD) is assumed to be an equivalent syndrome regardless of the type of traumatic event that precipitated it. However, the Diagnostic and Statistical Manual of Mental Disorders (4th ed.; DSM-IV; American Psychiatric Association, 1994) and previous research suggest that the clinical presentation of PTSD varies by trauma type. This study compared PTSD symptom profiles in three types of civilian trauma: sexual assault (n = 86), motor vehicle accident (n = 162), and sudden loss of a loved one (n = 185). Groups differed in overall PTSD severity and displayed distinct PTSD symptom patterns. Results suggest that different trauma types lead to unique variants of the PTSD syndrome, which may result from different etiological factors and may require different treatment approaches.
Moderate correlations were found between PTSD symptom severity, substance use, and adverse health outcomes. Mediational analyses indicated that substance use behaviors, especially alcohol and drug use, mediated the relationship between PTSD and health outcomes.
Walla Walla onions were irradiated with doses of 0.1, 0.3, 1.0, 2.0 and 3.0 kGy of gamma rays; 0.1, 1.0, 2.0, 3.0 and 5.0 kGy of electron beams; or 0.44 × 104 1.32 × 104, 3.52 × 104, 7.33 × 104 and 19.1 × 104 erg/mm± of UV. The onions were stored up to four weeks at 20–25 C. UV irradiated onions exhibited the greatest percentage of marketable onions and reduction in postharvest rots. Sprouting was obsened with control, UV and electron beam irradiated onions but not with gamma irradiated onions. Effect of gamma, electron beams and UV on pH, moisture, ascorbic acid and color were not significant. Onions became soft with the high dose of gamma radiation (3.0 kGy). Total sugar content was not affected by UV and electron beam but tended to be greatest at the 1.0 kGy gamma radiation. The effect of the radiation on the onion sensory scores was not clearly indicated except that 3.0 kGy gamma ray irradiated onions had the lowest firmness score.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
