This study examined the relationship between polyvictimization, psychological distress, and trauma symptoms in college men and women. Childhood victimization was common among participants. Regression analyses revealed that polyvictimization (i.e., high cumulative levels of victimization) is a better predictor of psychological distress and trauma symptoms than is any individual category of victimization (i.e., sexual, physical, peer/sibling, child maltreatment, witnessing/indirect, or property crime). Gender did not moderate the relation between victimization and distress and trauma symptoms. Implications for counselors are discussed. 相似文献

OBJECTIVE: There were three aims: (1). assess the prevalence of reported exposure to negative caregiver strategies in a community-based African-American population, (2). examine the sources of variation in caregiver parenting strategies, including demographic variables and child characteristics, (3). investigate whether mental disorders in young adulthood may differ based on reported degree of exposure to negative strategies. METHOD: The participants were 1197 African-Americans involved in a 1999-2001 young adult follow-up (age M=19.6, SD=.6) of an evaluation of school-based interventions in the Baltimore, MD metropolitan area. Measures included teacher-report of child aggression in first grade, parent-report of demographic variables in first and sixth grade, and young adult self-report of symptomatology, suicidal behaviors, and childhood caregiver discipline strategies. RESULTS: Fifty-four percent of the sample reported some use of physical discipline by caregivers. Lower family income and younger caregiver age, as well as teacher reports of child aggression, were related to reports of caregiver's high use of negative strategies. In addition, young adults who reported a high rate of negative caregiver strategies had a significantly increased risk for psychopathology and were over twice as likely to have experienced a history of suicidal ideation than those reporting low exposure.CONCLUSIONS: The results demonstrate the importance of examining variation in this population, with the poorest and the youngest using negative parenting strategies more frequently. In addition, the present study replicated previous findings of the link between negative caregiver discipline strategies and psychopathology. This association appears robust across diverse populations. The implications for preventive interventions are discussed. 相似文献

This study was conducted to examine factors associated with children's protective service workers' decision to remove sexually abused children from the family home. The decision to remove was analyzed relative to the following six factors: (1) nature of the abuse, (2) severity of abuse, (3) frequency of abuse (4) mothers' employment status, (5) mothers' compliance with a recommended treatment plan, and (6) mothers' belief of the victim. Discriminant function analysis revealed that the discriminant function containing mothers' compliance, mothers' belief, severity of abuse, mothers' employment status, and frequency of abuse, in order of importance of contribution, was significantly related to victims' removal from the home. 相似文献

Abstract Three modern views about the factors limiting oxygen uptake in healthy humans are set against the original (early 1920s) concept of A. V. Hill and colleagues. The majority view for most of the intervening time has been that cardiac output is the essential limiting function. Among recent research in support of this contention is that, in quadrupeds, pericardiectomy, which allows greater diastolic filling, elevates maximum oxygen uptake; however, the relevance to bipedal exercise can be questioned. In any case, algebraic analyses of model systems indicate that all identifiable stages on the oxygen transport pathway, from pulmonary diffusion to oxidative phosphorylation in skeletal muscle mitochondria, materially influence maximum uptake. Thus, if a high cardiac output is to be of benefit, all the other steps must function better too. Nevertheless, these two viewpoints concur that the limit to maximum oxygen uptake is somatic. In contrast, there are strong indications that at altitudes where oxygen availability is about half that at sea level, cerebral oxygenation is a limiting factor, and some recent experiments raise the possibility that it might be a substantial influence at sea level also. Clearly, consensus cannot yet be reached on the question posed in the title. 相似文献

ABSTRACTThere are well-known biological differences between women and men, especially in technical-coordinative variations that contribute to sex differences in performance of complex movements like the most important offensive action in volleyball, the spike jump. The aim of this study was to investigate sex-dependent performance and biomechanical characteristics in the volleyball spike jump. Thirty female and male sub-elite volleyball players were analysed while striking a stationary ball with maximal spike jump height. Twelve MX13 Vicon cameras with a cluster marker set, two AMTI force plates, surface EMG, and a Full-Body 3D model in Visual3D were used. Main findings include sex differences (P< .05) in jump height (pη2 = .73), approach [speed (pη2 = .61), step length], transition strategy [plant angle, neuromuscular activation (pη2 = .91), horizontal force maxima and impulses], acceleration distances [centre of mass displacement (pη2 = .21), minimal knee and hip angles], use of torso and arms [incline, angular velocity (pη2 = .23)]. Correlations support that the results cannot be explained fully by strength and power differences between sexes but represent the product of technical-coordinative variations. Their relevance is acknowledged for both sexes and numerous performance determinants displayed sex differences. The integration of such attributes into sex-specific training seems promising but its effect requires further investigation. 相似文献

There were two goals of the present study. The first was to create a scoring scheme by which 9-year-old Chinese children??s writing compositions could be rated to form a total score for writing quality. The second was to examine cognitive correlates of writing quality at age 9 from measures administered at ages 6?C9. Age 9 writing compositions were scored using a 7-element rubric; following confirmatory factor analyses, 5 of these elements were retained to represent overall writing quality for subsequent analyses. Measures of vocabulary knowledge, Chinese word dictation, phonological awareness, speed of processing, speeded naming, and handwriting fluency at ages 6?C9 were all significantly associated with the obtained overall writing quality measure even when the statistical effect of age was removed. With vocabulary knowledge, dictation skill, age, gender, and phonological awareness included in a regression equation, 35% of the variance in age 9 writing quality was explained. With the variables of speed of processing, speeded naming, and handwriting fluency additionally included as a block, 12% additional variance in the equation was explained. In addition to gender, overall unique correlates of writing quality were dictation, speed of processing, and handwriting fluency, underscoring the importance of both general automaticity and specific writing fluency for writing quality development in children. 相似文献
