In a sample of 780 South African child victims of rape (girls under the age of 18 years; age M= 10.5 yr., SD=4.8), 10% did not qualify for antiretroviral prophylaxis because HIV status at presentation was positive and a further 34.1% did not qualify because the rape was reported more than 72 hours after the alleged offense. Regression analyses indicated that child rape victims who reported that they had been sexually active prior to the rape constitute a particularly high risk group for HIV infection and suggest primary and secondary prevention programs should be designed to decrease sexual activity among children and to encourage more immediate reporting of rape among younger children, children who are not sexually active, and children who are incestuously abused. 相似文献

Transitions in caregivers' use of paid home help: associations with stress appraisals and well-being
This study examines the associations between transitions in paid home care and stress appraisals and psychological well-being of family caregivers of dementia relatives. The sample consisted of 264 caregivers who completed up to 3 interviews during 1 year. Longitudinal analyses (i.e., generalized estimating equations) showed that the onset of paid home care was associated with increases in feelings of worry and strain and a worsening in positive affect. Ending paid home care was strongly associated with a decrease in depressive symptoms, whereas sustained use of paid home care was related to reduced overload. Several possible mechanisms for the complex relationship of paid home care and family caregivers' stress appraisals and well-being are discussed. 相似文献

H. Szechtman and E. Woody (2004) proposed that obsessive-compulsive disorder (OCD) is caused by a malfunctioning brain security motivation system. In the current article, the authors' review of the model suggests that it is limited in the following ways: (a) It is built on a selective review of the empirical literature, (b) it offers no explanation for many important OCD phenomena, (c) it fails to distinguish OCD from generalized anxiety disorder, (d) some of the model's predictions are ambiguous or unfalsifiable, and (e) other predictions are refuted by previously published research. Models proposing that OCD is caused by a single dysfunctional mechanism, such as the security motivation model, have difficulty explaining the complexity and heterogeneity of OCD. 相似文献

Results of an analogue functional analysis indicated that noncompliant vocal behavior exhibited by a young girl with autism was maintained by negative reinforcement. Follow-up analyses suggested that the immediate escape contingency assessed in the demand condition did not appear to maintain the behavior. Instead, noncompliant vocal behavior occurred in response to directive prompts. Nondirective prompts reduced noncompliant vocal behavior to near zero. 相似文献

Different emotional reactions to different groups: a sociofunctional threat-based approach to "prejudice" 总被引:1,自引:0,他引:1
The authors suggest that the traditional conception of prejudice--as a general attitude or evaluation--can problematically obscure the rich texturing of emotions that people feel toward different groups. Derived from a sociofunctional approach, the authors predicted that groups believed to pose qualitatively distinct threats to in-group resources or processes would evoke qualitatively distinct and functionally relevant emotional reactions. Participants' reactions to a range of social groups provided a data set unique in the scope of emotional reactions and threat beliefs explored. As predicted, different groups elicited different profiles of emotion and threat reactions, and this diversity was often masked by general measures of prejudice and threat. Moreover, threat and emotion profiles were associated with one another in the manner predicted: Specific classes of threat were linked to specific, functionally relevant emotions, and groups similar in the threat profiles they elicited were also similar in the emotion profiles they elicited. 相似文献

C. Sedikides, L. Gaertner, and Y. Toguchi (2003) maintained that the self-enhancement motivation (as defined by tendencies to view oneself in overly positive terms) is universal. The present article challenges their claim. A review of the literature revealed that many studies contradict their findings regarding the domain-specific nature of East Asian self-enhancement. It is argued that Sedikides et al. did not replicate past research because they did not measure self-enhancement in their studies. The present article provides a theoretical basis for understanding cross-cultural differences in self-enhancement and considers the question of universality by exploring 2 different conceptualizations of positive self-regard. 相似文献

Differential item functioning (DIF) analyses of the Beck Depression Inventory-II (BDI-II) were conducted on samples of 267 women with breast cancer and 294 women with clinical depression. Patterns of items in which there was significant and nonsignificant DIF were identified using statistical tests and measures of DIF effect size. At the most general level, 15 of 21 BDI-II items were associated with nontrivial DIF suggesting that the item responses of these samples do not reflect the same underlying construct. Factor analyses of the BDI-II using a psychometrically defensible method for item level factor analysis supported the conclusions from the DIF analyses. These findings suggest that researchers and practitioners should apply caution when interpreting self-report depression symptoms in breast cancer patients. 相似文献

This study examined the cross-sectional factorial invariance of anxiety sensitivity in an ethnically diverse sample of adolescents (n = 173; mean age 15.5 years) and young adults (n = 291; mean age 20.1 years). Research in adult and youth samples suggests that anxiety sensitivity is best understood as a hierarchical construct with several lower-order factors. Factor models based on previous research using both adult and youth samples were compared and a hierarchical model with three lower-order factors provided the best fit to the data. Results supported the hypothesis that the factor structure of the Anxiety Sensitivity Index was invariant across age and gender. The factor scores also demonstrated differential correlations with symptoms of anxiety and depression. Results are discussed with regard to construct validation and understanding the structure of anxiety sensitivity in youth. 相似文献

We examined the psychometric properties and factor structure of a Cambodian translation of the Anxiety Sensitivity Index (ASI) and an Augmented ASI (the ASI supplemented with a 9-item addendum that assesses additional Cambodian concerns about anxiety-related sensations). Both the ASI and the Augmented ASI distinguished among three diagnostic groups: highest score, PTSD with panic disorder (PP group); next, panic disorder without PTSD (P group); and then, other disorders than PTSD or panic disorder (O group). In the discriminant function analysis using the Augmented ASI, the best classificatory predictor (PP vs. P vs. O) was an Addendum item (“It scares me when I stand up and feel dizzy”). The principal component analysis (oblimin rotation) of the ASI yielded a 3-factor solution (I, Weak Heart Concerns; II, Control Concerns; III, Social Concerns) and of the Augmented ASI, a 4-factor solution (I, Weak Heart Concerns; II, Control Concerns; III, Wind Attack Concerns; IV, Social Concerns). The item clustering within the factor solution of both the ASI and Augmented ASI illustrates the role of cultural syndromes in generating fear of mental and bodily events. 相似文献

Visual working memory plays a central role in most models of visual search. However, a recent study showed that search efficiency
was not impaired when working memory was filled to capacity by a concurrent object memory task (Woodman, Vogel, & Luck, 2001).
Objects and locations may be stored in separate working memory subsystems, and it is plausible that visual search relies on
the spatial subsystem, but not on the object subsystem. In the present study, we sought to determine whether maintaining spatial
information in visual working memory impairs the efficiency of a concurrent visual search task. Visual search efficiency and
spatial memory accuracy were both impaired when the search and the memory tasks were performed concurrently, as compared with
when the tasks were performed separately. These findings suggest that common mechanisms are used to process information during
difficult visual search tasks and to maintain spatial information in working memory. 相似文献
