The utility of somatic symptoms as indicators of depression and anxiety in military veterans with chronic obstructive pulmonary disease.

The interrelationship between medical illnesses and psychological distress has received increasing attention in the last several years. Partly at issue is the best way to diagnose mental health problems such as depression and anxiety in medical populations. Specifically, are somatic symptoms a valid indicator of depression and anxiety in a medical population? Furthermore, do anxiety and depression remain as distinct constructs for this population, or do they combine to represent general distress? We examine these issues using confirmatory factor analysis in a sample of 202 military veterans with chronic obstructive pulmonary disease. Results indicate best fit for a model of depression and anxiety for which the constructs remained separate rather than as combined indicators of general distress. Furthermore, in this model, somatic symptoms are retained as valid indicators of psychological distress for this sample.

Social isolation, impulsivity and depression as predictors of aggression in a psychiatric inpatient population.

Aggressive behavior among psychiatric inpatients remains an issue of concern for staff, families and patients themselves. At the present time, studies examining prediction of aggression among psychiatric inpatients have focused mainly on diagnostic or demographic risk factors. Unfortunately little is known about specific social functioning and personality risk factors that may help identify specific individuals at risk for aggressive behavior. Given that many individuals who have engaged in violent criminal behavior have been observed to experience a combination of social isolation, depression and impulsiveness, it is possible that this same combination of traits may function as a predictor of aggression among psychiatric inpatients. The current study examines whether psychiatric inpatients with a combination of social isolation, depression and impulsivity are significantly more likely to become aggressive than other psychiatric inpatients without that combination of factors. Results indicated that impulsivity functioned as a positive predictor of aggression, whereas depression acted as a protective factor. Perceived social support did not appear to relate strongly to aggression. Further, physicians' ratings of hostility were more predictive of aggressive incidents than were self-reports of hostility. Clinical implications of these findings are discussed.

An analysis of females convicted of sex crime in the state of Florida.

The phenomenon of female sex offenders has been poorly explored in the scientific literature. In particular, little exploration of possible subtypes of female offenders has been conducted. In the current study, 279 female sexual offenders convicted of a total of 940 separate criminal offenses were examined using hierarchical cluster analysis. Results indicated that female sexual offenders tended to engage in behaviors that fell within three distinct patterns differing according to perpetrator characteristics, victim age, and the use of force. These results suggest that female sexual offenders are a heterogeneous population and a more in-depth investigation may be necessary.

The influence of gender and ethnicity on judgments of culpability in a domestic violence scenario.

Using an experimental analog design, in this study we examined 503 European American, African American, and Latino undergraduate students' responses to a domestic violence scenario in which the ethnicity and gender of the perpetrator were manipulated. Results indicated that participants perceived perpetration of domestic assault significantly more criminal when committed by a man than when committed by a woman. That finding was robust across European Americans, African Americans, and Latinos and was expressed by both genders. Also, European American participants expressed significantly more criticism toward African American perpetrators of assault than they did toward European American and Latino perpetrators of the exact offense, suggestive of racial bias consistent with stereotypes about African Americans being excessively aggressive. Finally, Latino participants expressed significantly more sympathy toward women who assault their husbands than toward assaulting husbands. Implications of the findings are discussed.
