Most of what we know about sexual abuse comes from efforts to examine female children victimized by men. Although some researchers have identified similarities between male and female victims of sexual abuse, few studies have examined gender-specific factors associated with sexual health practices among homeless adolescents. The aim of this study was to explore how gender and history of sexual abuse influence cognitive-perceptual and behavioral factors associated with sexual health practices of homeless adolescents. This study was a secondary analysis of data collected for a cross-sectional study of the sexual health practices of homeless adolescents. The sample consisted of 414 youths (104 males who reported sexual abuse and 124 who did not; and 95 females who reported sexual abuse and 75 who did not; 16 did not provide these data). Homeless adolescent females with a history of sexual abuse scored higher (indicating a shorter perspective) on a measure of future time perspective than females with no sexual abuse. Males who reported no sexual abuse scored higher than abused females on perceived health status and higher than abused males on assertive communication. With respect to perceived health status, males who reported no sexual abuse scored significantly higher than females who reported sexual abuse (p = .04). Males with no sexual abuse had significantly higher assertive communication scores than did males who had experienced sexual abuse (p = .015). We found that male and female abuse victims differ in terms of their cognitive-perceptual and behavioral factors associated with sexual health practices. Early identification of those who have been abused is critical so that interventions can be developed. Effective short-term interventions are needed for the adolescent victims of Child Sexual Abuse (CSA), particularly those who are homeless and prone to further sexual victimization. 相似文献

This paper describes a 7.5 year retrospective study of all patients discharged from inpatient forensic services to forensic community team (FCT) follow-up from the Auckland Regional Forensic Psychiatry Service. Patients' files were studied for clinical, criminal, and risk data, type of service delivered, and final level of function achieved in the community. Rearrest, re-hospitalization, and reimprisonment data were obtained from clinical, court, and prison records.105 patients were included. The most common diagnosis was a psychotic disorder, and index offending behaviour was typically violent. The median period of inpatient stay was 36 months and mean subsequent FCT follow-up 21.7 months (SD 17.8). The majority of patients were from Maori and Pacific Island ethnic groups. At the end of the study, half were in independent living, half were in some form of employment, and 19% were readmitted to a forensic hospital.One patient was rearrested but not reimprisoned whilst under forensic community team care. However, 9 of the 48 who were discharged to general mental health services were rearrested and 5 reimprisoned. Only two offences were as serious as the original index offence.Broad based assertive, mandated, and committed forensic rehabilitation can achieve high quality outcomes. These levels of function may not be sustained under less assertive care. 相似文献

Social discounting 总被引:1,自引:0,他引:1
The amount of money a person was willing to forgo in order to give 75 dollars to another person decreased as a hyperbolic function of the perceived social distance between them. Similar hyperbolic functions have previously been shown to describe both time and probability discounting. 相似文献

The use of structural equation modeling in cross-cultural personality research has become a popular method for testing measurement invariance. In this report, we present an example of testing measurement invariance using the Sense of Coherence Scale of Antonovsky (1993) in 3 ethnic groups: Chinese, Japanese, and Whites. In a series of increasingly restrictive constraints on the measurement models of the 3 groups, we demonstrate how to assess differences among the groups. We also provide an example of construct validation. 相似文献

Correlation Weights in Multiple Regression 总被引:1,自引:0,他引:1
A general theory on the use of correlation weights in linear prediction has yet to be proposed. In this paper we take initial
steps in developing such a theory by describing the conditions under which correlation weights perform well in population
regression models. Using OLS weights as a comparison, we define cases in which the two weighting systems yield maximally correlated
composites and when they yield minimally similar weights. We then derive the least squares weights (for any set of predictors)
that yield the largest drop in R
2 (the coefficient of determination) when switching to correlation weights. Our findings suggest that two characteristics of
a model/data combination are especially important in determining the effectiveness of correlation weights: (1) the condition
number of the predictor correlation matrix, R
xx
, and (2) the orientation of the correlation weights to the latent vectors of R

Abstract Two experiments studied memory for the appearance of a Danish 20 kroner coin. The coin bears the portrait of Queen Margrethe II in profile, facing to the right. Previous studies have examined memory for British coins, which similarly bear a right-facing portrait of Queen Elizabeth II. They have revealed the occurrence of a mnemonic illusion, in that British people tend to believe the portrait faces left. This finding has been attributed to the occurrence of a joint coin-stamp schema. British stamps bear a left-facing profile of the Queen, and it is possible that information from the stamp predominates in the formation of the schema. In the case of Denmark, however, stamps bear a full-face portrait of the Queen. Nevertheless, the present experiments showed that the Coin Head Illusion is also found in Denmark. That is, the number of participants recalling the Queen's head as facing to the right was significantly below even the chance level of 50%. Further, this result occurred both for residents of Denmark and for visitors to Denmark. These findings suggest that the bias underlying the Coin Head Illusion may be a more general one than that envisaged by the joint coin-stamp schema hypothesis. 相似文献

Four experiments were conducted to provide further support for a dual-process approach to conjunction errors in recognition memory over a single-process approach. In Experiments 1, 2a, and 2b study words were repeated once (2 presentations) or several times (8 or 16 presentations), and a response signal delay (RSD) was manipulated (short vs long). Short RSD groups produced lower hit rates but higher conjunction error rates compared to long RSD groups. Repetition effects on conjunction errors occurred for short RSD but not long RSD groups. In Experiment 3, additional judgements on new items were solicited to show that the “null” effects for long RSD groups in the earlier experiments were, in fact, illusory. Together, the experiments provide evidence for recollection-based rejections of conjunction lures and support a dual-process theory of recognition memory over a single-process model. 相似文献

The literature on mental toughness is characterized by a general lack of conceptual clarity and consensus as to its definition, as well as a general failure to operationalize the construct in a consistent manner. This study addressed two fundamental issues surrounding mental toughness: how can it be defined? and what are the essential attributes required to be a mentally tough performer? Ten international performers participated in either a focus group or one-toone interviews, from which a definition of mental toughness and the attributes of the ideal mentally tough performer emerged. The resulting definition emphasized both general and specific dimensions, while the 12 attributes covered self-belief, desire/motivation, dealing with pressure and anxiety, focus (performance-related), focus (lifestyle-related), and pain/hardship factors. 相似文献

A considerable amount of research has demonstrated the value of imagined contact in reducing social prejudice. The current study investigated the efficacy of imagined intergroup contact in improving attitudes towards male homosexuals on both explicit and implicit measures. Eighty-five heterosexual undergraduate students were randomly allocated to one of three conditions: imagined interaction, prime control or unrelated imagery control. Overall, no significant differences were found between the imagery conditions for either the explicit or implicit attitude measures, even when controlling for prior contact. Accordingly, the present findings, unlike those of Turner et al. (Journal of Personality and Social Psychology 93: 369–388, 2007b) and (Group Processes & Intergroup Relations 10: 427–441, 2007a), do not offer support for the effectiveness of indirect contact in reducing prejudice toward male homosexuals. Some explanations for the inconsistency of findings are discussed. 相似文献

The influences of different action-outcome scenarios on children's evaluative judgments and inferences of outcome intentionality were assessed. One hundred forty-five kindergartners, 2nd graders, and 4th graders heard 4 stories about child actors who engaged in 1 action or 3 equifinal actions and caused a positive or negative outcome. The stories made no mention of the actors' anticipated outcome so that we could assess the children's inferences of whether the actors wanted and had tried to cause the outcome. Children also rated their liking for the actors and the actors' morality. Children's moral and liking judgments were not significantly differentiated by action condition. However, actors who caused positive outcomes received favorable liking and moral judgments, and actors who caused negative outcomes received neutral liking and moral judgments. Children's intentionality inferences varied by the actors' actions and were moderated by outcome valence. The authors discuss children's apparent use of the valence rule when inferring intentionality and their reluctance to judge harshly actors who cause negative outcomes when not privy to the actors' intentions. 相似文献
