不同发展阶段的习得性长时程突触增强对新学习的影响

在慢性实验条件下观察到大鼠由学习训练所产生的海马CA_3区习得性长时程突触增强,它的不同发展阶段对新学习任务的习得有不同的作用:(1)在它的形成阶段及巩固阶段对新学习均有易化作用,虽然两个阶段突触效应增强的程度都处于相同的高水平,但后者的易化作用相对要大些,提示这两个发展阶段突触的可塑性变化是有差异的;还有,新学习任务的训练并没有引起突触效应的进一步增强,表明突触效应的长时程增强有“饱和”现象。(2)在它消退后,对新学习任务的习得没有影响。上述结果提示学习的组织形式不同,可从突触机制上影响学习的效果,并进一步证明习得性长时程突触增强是学习和记忆的神经基础。     

Post-Adoption Services for High-Risk Families and Their Children: Preliminary Results of a State-Wide Intervention

Despite well-documented post-adoption needs of adoptive families, most states provide no or very limited post-adoption services. This study describes Right Turn® (RT), a state-wide program for strengthening adoptive families and preventing adoption dissolution. Results suggest: (a) RT is serving its targeted audience of adoptive families with challenging problems indicated by older adopted children with a history of multiple placements, extended time in social services systems, and a host of mental health challenges; and (b) adoption training, family support when navigating access to post-adoption services, and collaboration with adoption-competent therapists appeared to have helped improve program outcomes.

"爱情"与"友谊"概念表征的差异——基于字词联想的比较

运用字词联想法对大学生爱情和友谊概念表征的异同进行了初步探究.以"爱情"和"友谊"为靶词,让被试进行自由联想,之后对搜集到的11136个联想词进行内容分析,在前人研究的基础上最终编码为18个范畴.结果显示,爱情相对需要更多的理性与情感投入、经历更多的痛苦、肩负更多的责侄,容易联想到婚姻、家庭、命运缘分,而友谊较少牵扯.与爱情相比,友谊更易于转化为爱情,而经历过爱情的人很难再回归到友谊.这些结果与日常观念相符,为如何处理爱情和友谊的关系提供了实征指导.     

Homeless Adults’ Recovery Experiences in Housing First and Traditional Services Programs in Seven European Countries

Across Europe, as governments turn to housing-led strategies in attempts to reverse rising rates of homelessness, increasing numbers of Housing First (HF) programs are being implemented. As HF programs become more widespread, it is important to understand how service users experience them compared to the more prevalent traditional treatment-first approach to addressing long-term homelessness. Although there is a large body of research on service users’ experiences of Housing First compared to treatment-first in North American contexts, comparatively less is known about how these two categories of homeless services are experienced in the European context. In a correlational and cross-sectional study, part of a larger examination of homelessness in Europe, participants (n = 520) engaged with either HF (n = 245) or traditional services (TS; n = 275) programs in seven countries completed measures of their experiences of services (consumer choice, housing quality, and service satisfaction) and recovery (time in independent housing, psychiatric symptoms, and community integration). Across the seven countries, participants engaged with HF programs reported experiencing more consumer choice, better perceived housing quality, and more satisfaction with services than participants engaged in TS programs. Participants in HF programs also reported a greater proportion of time in independent accommodation, fewer psychiatric symptoms, and more community integration. Varying patterns of association between experiences of services and recovery outcomes were observed. Findings indicate HF consistently predicts greater recovery than TS across diverse sociopolitical and economic contexts. Implications of findings for configurations of homeless services and homeless services policy are discussed.     

Opinions of personality disorder experts regarding the DSM-IV personality disorders classification system

OBJECTIVE: To survey the opinions of personality disorder (PD) experts on possible revisions in the classification system for PDs in the DSM-V. METHOD: Four hundred members of two international associations, the Association for Research on Personality Disorders, and the International Society for the Study of Personality Disorders, were asked to take a 78-item web survey. RESULTS: Of the experts who completed the survey (N = 96), 74% felt that the DSM-IV's categorical system of PD diagnosis should be replaced. Eighty percent felt that PDs are better conceived of as personality dimensions or illness spectra, than as categories. The most frequently endorsed alternative system for PDs was a mixed system of categories and dimensions. Most experts preferred the PDs to remain on Axis II. Only 31.3% wanted the term, "Borderline Personality Disorder," retained in the DSM-V. CONCLUSIONS: A clear majority of the PD experts were dissatisfied with the current diagnostic system for PDs.     

Predictors of Cancer Worry in Unaffected Women from High Risk Breast Cancer Families: Risk Perception is not the Primary Issue

Some women at increased familial risk of breast cancer experience elevated levels of cancer-specific worry, which can possibly act as a barrier to screening, and may be a significant factor in decisions regarding risk-reducing surgery. The aim of this study was to comprehensively examine predictors of cancer-specific worry in high risk women and to test a model which proposes that perceived breast cancer risk mediates the impact of other factors on worry. 1,437 unaffected women from high risk breast cancer families completed questionnaires and interviews. Path analysis was used to test the model of potential predictors of cancer worry, including familial, personal and psychological variables, mediated via perceived cancer risk. Levels of cancer-specific worry were generally low despite an average perceived risk of 50.3%. The goodness-of-fit of the proposed model was poor, explaining only 9% of the variance for perceived risk and 10% of the variance for cancer specific worry. An alternative model of a direct relationship between all of the predictor variables and cancer worry, explained 24% of the variation in cancer worry. General anxiety, perceived risk, the stressful impact of recent cancer related events, a relative risk greater than 10, being closer in age to the youngest breast cancer diagnosis in family, and knowledge of personal mutation status, all independently contributed to cancer worry. Addressing general affective responses, experiences of recent cancer related events, in addition to education about personal risk, should be considered in counselling women with elevated cancer worry. Risk perception appears to act independently of other factors in its formulation and impact on cancer worry. Further research on the way in which women come to perceive their risk is indicated.

Parent training for children with pervasive developmental disorders: a multi‐site feasibility trial

The primary purpose of this study was to evaluate the feasibility of a structured, manual‐based parent training (PT) program designed to reduce noncompliant behavior and enhance adaptive behavior in children with Pervasive Developmental Disorders (PDD) who were taking medication for irritability, tantrums, aggression, and self‐injury. Children (N = 17, mean age 7.7 ± 2.6 years) with PDD were enrolled in a 24‐week structured PT protocol. Parental attendance to sessions (93%), satisfaction with the program (92%), and adherence to PT assignments (80%) were excellent. The program was adequately implemented with a mean treatment integrity rate of 94%. Parent‐reported rates of noncompliance were reduced by 39%; irritability was reduced by 34%; and daily living skills were enhanced by 19%. Parenting stress was also reduced by 14%. However, these results must be interpreted with caution because the study did not include a control group. The study supports feasibility of the PT program, which will be used in an randomized clinical trials (RCT). Copyright © 2007 John Wiley & Sons, Ltd.

Parent Involvement in School Conceptualizing Multiple Dimensions and Their Relations with Family and Demographic Risk Factors

Parent involvement (PI) in school is associated with more positive academic performance and social competence in children. However, there are inadequacies in current measures of PI and a need for a better understanding of predictors of PI. In this study, measures were obtained from a normative sample of 387 children in kindergarten and first grade from high-risk neighborhoods in 4 different sites. First, a confirmatory factor analysis of a theoretical factor model of PI identified 6 reliable multiple-reporter PI factors: Parent–Teacher Contact, Parent Involvement at School, Quality of Parent–Teacher Relationship, Teacher's Perception of the Parent, Parent Involvement at Home, and Parent Endorsement of School. Next, the relations among 3 specific family and demographic risk factors—parental education level, maternal depression, and single-parent status—and these 6 PI factors were examined using path analyses in structural equation modeling. Results indicated that the 3 risk factors were differentially associated with the 6 PI factors: Parental education was significantly associated with 4 PI outcomes, maternal depression was significantly associated with 5 PI outcomes, and single-parent status was significantly associated with 3 PI outcomes. No significant ethnic group differences between African American and Caucasian families were found in these relations.
