The involvement of anger in the psychological adjustment of current war veterans, particularly in conjunction with combat-related posttraumatic stress disorder (PTSD), warrants greater research focus than it has received. The present study concerns a brief anger measure, Dimensions of Anger Reactions (DAR), intended for use in large sample studies and as a screening tool. The concurrent validity, discriminant validity, and incremental validity of the instrument were examined in conjunction with behavioral health data for 3,528 treatment-seeking soldiers who had been in combat in Iraq and Afghanistan. Criterion indices included multiple self-rated measures of psychological distress (including PTSD, depression, and anxiety), functional difficulties (relationships, daily activities, work problems, and substance use), and violence risk. Concurrent validity was established by strong correlations with single anger items on 4 other scales, and discriminant validity was found against anxiety and depression measures. Pertinent to the construct of anger, the DAR was significantly associated with psychosocial functional difficulties and with several indices of harm to self and to others. Hierarchical regression performed on a self/others harm index found incremental validity for the DAR, controlling for age, education, military component, officer rank, combat exposure, PTSD, and depression. The ability to efficiently assess anger in at-risk military populations can provide an indicator of many undesirable behavioral health outcomes.

At least four conceptually distinct mechanisms may mediate relations between parasite-stress and cultural outcomes: genetic evolution, developmental plasticity, neurocognitive flexibility, and cultural transmission. These mechanisms may operate independently or in conjunction with one another. Rigorous research on specific mediating mechanisms is required to more completely articulate implications of parasite stress on human psychology and human culture. 相似文献

The exhibition of actions that are causally unnecessary to the outcomes with which they are associated is a core feature of human cultural behavior. To enter into the world(s) of their cultural in-group, children must learn to assimilate such unnecessary actions into their own behavioral repertoire. Past research has established the habitual tendency of children to adopt the redundant actions of adults demonstrated directly to them. Here we document how young children will do so even when such actions are modeled to a third person regardless of whether children are presented with the test apparatus by the demonstrating, and assumedly expert, adult or by the observing, and assumedly naive, adult (Experiment 1), whether or not children had opportunity to discover how the apparatus works prior to modeling (Experiment 1), and whether or not children's attention was drawn to the demonstration while they were otherwise occupied (Experiment 2). These results emphasize human children's readiness to acquire behavior that is in keeping with what others do, regardless of the apparent efficiency of the actions employed, and in so doing to participate in cultural learning. 相似文献

Varying risk factors for both incarceration and mental health diagnoses have been identified for female juveniles, highlighting the need for gender-specific assessments and treatment protocols. The purpose of this study is to determine how the prevalence rates of mental health symptoms differ in male and female juvenile offenders. It was hypothesized that the prevalence rates would be greater for females than males. This study found significant differences between males and females on several clinical scales. These findings are consistent with past studies that have identified differences in mental health symptoms between genders. 相似文献

Obesity not only increases risk for morbidity/mortality, but also impacts the quality of life of obese individuals. In the United States, black women have the highest prevalence of obesity of any other group with approximately 80% of black women over age 20 having a body mass index (BMI)????25?kg/m2. We aimed to examine the association between BMI and quality of life in this high risk population compared to this association in white women, using the Impact of Weight on Quality of Life (IWQOL)-Lite questionnaire. Data from 172 black women (mean BMI?=?35.7; age?=?40.5) and 171 white women (mean BMI?=?35.5; age?=?40.4) were collected between 2000 and 2010 analyzed in 2010. The mean IWQOL-Lite total score was 81.6 for black women compared to 66.9 for white women, a statistically significant difference. Hierarchical linear regression models revealed a significant BMI-by-race interaction indicating that the relationship between BMI and IWQOL-Lite score was moderated by race. Our findings suggest notable differences in weight-related quality of life in black and white women. At similar BMIs, black women consistently reported better quality of life than white women on all IWQOL-Lite subscales. The greatest difference in IWQOL-Lite scores between black and white women was seen in the self-esteem subscale. Additional research is needed to understand how to incorporate the weight perspectives of black women into weight management messages and interventions. 相似文献

Poor medication adherence is a leading cause of excessive cardiovascular morbidity among African Americans. Many adherence-promoting interventions have addressed economic barriers, improved the patient-provider relationship, simplified regimens, and used reminder systems; however, the problem of low adherence remains intractable. Meanwhile, positive psychological attributes that might serve to promote medication adherence have not been fully explored. To address this gap, we examined the association between happiness and medication adherence among low-income African Americans with hypertension treated in a safety-net setting. Data were obtained from the Alabama Collaboration for Cardiovascular Equality, 2007?C2008. Happiness was measured using the 4-item scale of Lyubomirsky and Lepper; low, moderate, and high happiness were defined by tertiles because of the non-normal distribution. Medication adherence was assessed with the Morisky Medication Adherence Scale. Associations were quantified with ordinal logistic regression. Our sample of 573 African Americans was 71.6?% female and had an average age?±?SD of 53.6?±?9.7?years and a median happiness score of 5.2. Compared to participants with low happiness, the odds (OR; 95?% CI) of being in a better medication adherence category were greater for those with moderate (1.53; 1.02?C2.27) and high (2.26; 1.52-3.37) happiness, after adjusting for age, sex, income, education, and difficulty paying for medical care. Within this cohort of low-income African Americans with hypertension, participants with greater happiness exhibited better medication adherence. Although one interpretation of our study is that more adherent patients are naturally happier, our findings raise the possibility that adding happiness-boosting components may increase the effectiveness of more traditional adherence interventions. 相似文献

A novelty preference method was used to examine memory processes in profoundly, severely, and moderately retarded persons. After viewing a photograph of a face for 30 seconds, subjects were shown the study face and a new one after intervals ranging up to 3 minutes. Data were obtained from 30 of 56 subjects with this method. Of the 30 subjects, 20 showed significant preference for looking at the new face in the test. Recognition memory as indexed by novel looking declined over the retention interval. Memory was stronger but decayed more rapidly for higher memorable (distinctive) faces. With refinement, the novelty preference method holds promise for the study of cognitive processes in nonverbal persons. But, since memory is being inferred from response preferences which reflect an induced motivational state, satiation, the relationship between this state and memory must be established. 相似文献

Two studies compared judgments about aggressive components of jealous reactions to the partner and to the rival, specifically, emotional (anger), cognitive (blame), and behavioral components. The first study randomly assigned 172 young women and men to two questionnaires on jealous reactions to mild (flirting) and serious (cheating) transgressions. One questionnaire assessed standards for appropriate behavior and perceptions of how people usually react. The second questionnaire asked people to report how they had reacted or, if not experienced with a sexual transgression, how they would react. The second study asked 113 people to imagine a situation in which they knew their partner had been sexually unfaithful. There were three major findings that were interpreted in the context of courtship, a time when attention is focused on the qualities of one's potential long-term partner. First, the jealous individual's anger and blame were focused more on the partner than the rival. Second, mean anger and blame scores given the partner were well matched. In contrast, the rival received more anger and blame than deemed appropriate and considerably more anger than blame. These data suggest that, in the context of courtship, a rival is not simply a competitor. Third, men were more inclined to think about aggressive action against the rival but women were more emotionally and behaviorally reactive to the rival. The latter result implies that, in the context of competition for an established romantic partner, a rival is more salient for women than for men. © 1993 Wiley-Liss, Inc. 相似文献
