The purpose of this study was to assess ethnic differences in the negative symptom profile of 25 Anglo American and 26 Mexican American subjects with schizophrenia. Subjects were rated at the end of a 1-2-week medication washout period (time 1) and at discharge (time 2) with the Negative Symptoms Assessment (NSA), Brief Psychiatric Research Scale, (BPRS), the [Diagnostic and Statistical Manual of Mental Disorders (4th edition)] DSM-IV negative factor score and LAECA acculturation scale. Total NSA scores were significantly higher among Mexican Americans both at time 1 and time 2. Among the five subscales of the NSA, ethnic differences were significant only for the Cognition subscale at time 1. Results indicate no ethnic differences in core negative symptoms (alogia, avolition, flat affect), but do suggest that a cognition-related factor differs between Mexican American and Anglo American schizophrenic patients.
Much has been written about intimate violence and American Indians, but little empirical data are available. This study investigated the prevalence and characteristics of intimate violence among 104 members of a Southwestern American Indian tribe. A semistructured psychiatric interview and a measure of intimate violence were administered to 104 tribal community members from an overall study sample of 582. Both men and women reported high rates of lifetime (91%) and recent (31%) intimate violence; much of this behavior was interactive. However, female victims were more likely to require medical attention because of sustained injuries and to have their children involved with the violence than were male victims. For women in this study, forced sex was the only incident significantly associated with lifetime affective disorders and lifetime posttraumatic stress disorder. In this Southwestern American Indian community, intimate violence appears to be another variable in an environmental context that includes alcoholism, other psychiatric disorders, and traumatic events.
