This study examines how substance use is associated with the health and safety of homeless youth using cross-sectional, self-report
data from 285 homeless adolescents. Path models were used to examine concurrent relationships between youth’s substance use
and multiple aspects of their health and safety, including measures of psychological distress, housing risk and instability,
and medical problems. Substance use was examined with both global (i.e., a composite of days of use across various drugs and
alcohol) and specific (i.e., rates of use of specific drugs, injection drug use) measures. After controlling for demographic
and historical variables, number of days of use was significantly related to psychological distress, whereas injection drug
use was significantly related to housing risk. Examination of specific drugs revealed relationships between psychological
distress and the use of alcohol, cocaine, and amphetamines, and a specific relationship between housing risk and the use of
heroin. None of the measures of substance use was significantly related to youth’s medical problems. Implications for interventions
with homeless adolescents are discussed. 相似文献

Using an ecological framework, the authors explore the reasons for peer discrimination and harassment reported by many Chinese American youth. They draw on longitudinal data collected on 120 first- and second-generation Chinese American students from two studies conducted in Boston and New York. Our analyses suggested that reasons for these experiences of harassment lay with the beliefs about academic ability, the students' immigrant status and language barriers, within-group conflicts, and their physical appearance that made them different from other ethnic minority or majority students. Implications and future research are also discussed. 相似文献

This chapter provides an overview of non family contexts that shape the development and adjustment of children and youth from immigrant families. It also describes the four chapters in this special issue that focus on peer, network, legal, and institutional contexts that influence the lives of immigrant parents and their children. Directions for future research on the social contexts of development in immigrant families are discussed. 相似文献

Fifteen children with high-functioning Autism Spectrum Disorder (ASD) and 15 children with typical development completed an attentional cuing task using peripheral cues (exogenous orienting) and central cues (endogenous orienting). Results showed that participants with ASD had impaired exogenous and intact endogenous orienting. The pattern of exogenous orienting was related to motor functioning. Individuals with ASD who had poor motor functioning displayed slowed exogenous orienting. However, individuals with ASD who had relatively good motor functioning showed typical levels of exogenous orienting when given a short time but decreased orienting when given a longer amount of time. These results suggest attention impairments in ASD may not be specific to social orienting and instead may represent a more general orienting impairment. 相似文献

The purpose of this study was to examine the occurrence of depression among adolescents attending family planning clinics, and to determine the relationship among depression, a history of sexual abuse, and other risk behaviors. The sample consisted of 279 minority females. Results of the study indicated that 40 adolescents (14.3%) scored at or above a raw score of 77 for depression based on the Reynolds Adolescent Depression Scale (RADS). This suggests that these adolescents should be identified for further evaluation. Results of the Stepwise Linear Regression indicated that a history of sexual abuse was the most potent factor in predicting depression. These findings highlight the importance of screening concurrently for depression and a history of sexual abuse in family planning and other healthcare settings. 相似文献

Genetic counseling is a communication process with two main functions: information provision and supportive counseling. The information transmission function may be compromised by disruptions that occur during counseling. At least two mediators are possible: (a) disruptions may interfere with memory by creating distractions and divided attention during encoding or (b) disruptions may degrade the flow of interaction which requires that participants engage in conversation repair rather than the task at hand. This study examined both alternatives in a group of parents (N=20 families, 40 individual parents) whose infant had received a newborn screening for cystic fibrosis (CF). Upon arrival at the hospital, each parent completed a questionnaire designed to assess his or her knowledge of CF. Their interaction with the genetic counselor was videotaped and coded for the presence of disruptions. Six weeks after the counseling, parents again completed the knowledge measure. The data showed a direct negative effect for disruptions during counseling on memory for CF-related risk information six weeks later. Disruptions also produced the anticipated effect on conversation, but counter to expectations, interruptions of conversation flow was positively associated with knowledge at time 2. 相似文献

Event-related brain potentials (ERPs) were recorded while participants read and made acceptability judgments about sentences containing three types of adjective sequences: (1) normal sequences--e.g., Jennifer rode a huge gray elephant; (2) reversed sequences that violate grammatical-semantic constraints on linear order--e.g., *Jennifer rode a gray huge elephant; and (3) contradictory sequences that violate lexical-semantic constraints on compositionality--e.g., *Jennifer rode a small huge elephant. Relative to the control condition, the second adjective elicited a reduced N400 and an enhanced P600 in both the reversal condition and the contradiction condition. We present several alternative accounts of these two effects, but favor an interpretation which treats them as reflecting semantic and syntactic aspects of a temporary reanalysis of the adjective order construction. Furthermore, relative to the control condition, the final noun elicited a robust N400 in the contradiction condition but not in the reversal condition. We suggest that this effect indexes the full registration of the lexical-semantic incompatibility of the two adjectives in the contradiction condition. Finally, we discuss how all of these findings fit into the broader context of recent ERP studies that have reported atypical N400s and robust P600s in response to certain types of semantic anomalies. 相似文献

Humor can reflect the healthy release of feelings during the counseling process, the type of emotional release that leads to significant therapeutic gains. It can also be a disturbing distraction, possibly causing early termination, if used inappropriately. Counselors need to exert particular caution before attempting to apply humor in working with a client from a culture different from the counselor's. This article explores the available literature and offers contributions on the subject from 4 “ethnically diverse” perspectives. Finally, a general approach based on existential theory is presented along with 5 general conditions to ascertain the appropriate use of humor. 相似文献

This paper offers a philosophical `history' of the nature of`public discourse' – a basic element of human rights. It beginswith Enlightenment views from Condorcet and Jefferson, turns to Dewey,and then to Habermas. Over a couple of centuries not only does thecentral character of discourse change but so too does the definition ofa public person. 相似文献
