《大学生主观幸福感量表》的编制

根据国内外关于主观幸福感的文献和已有的研究经验,编制了大学生主观幸福感问卷。以往大多数研究认为,主观幸福感由生活满意度和情绪体验两个基本成分构成,本研究认为主观幸福感还应包括社会性行为和人际关系等成分。对376名大学生进行初测,通过探索性因素分析,表明大学生主观幸福感由自我满意、家庭满意、消极情绪、积极情绪、精力、生活满意、社会性行为和人际关系8个维度构成,共41个项目。对511名大学生施测41个项目的主观幸福感问卷,进行验证性因素分析,结果表明,上述结构是合理的。     

Culturally Sensitive AIDS Educational Videos for African American Audiences: Effects of Source, Message, Receiver, and Context

The importance of using culturally sensitive educational materials in HIV-related interventions with racial and ethnic minority groups is widely recognized. However, little empirical research has been conducted to assess the relative effectiveness of different techniques for creating culturally sensitive AIDS educational videos. Two field experiments with three samples of African American adults (N = 174, 173, and 143) were conducted to assess how source characteristics (race of communicator), message characteristics (multicultural message vs. culturally specific message), and audience characteristics (racial distrust and AIDS-related distrust) influence proximate (perceptions of the message's credibility and attractiveness) and distal (AIDS-related attitudes, beliefs, and behavioral intentions) output variables for AIDS educational videos. In Study 1, an AIDS video with a culturally specific message was rated as more credible, more attractive, and of higher quality than was a video with a multicultural message. The multicultural message was rated less favorably when delivered by a White announcer than when the announcer was Black. In Study 2, the same pattern was replicated with a second community sample and a campus-based sample. Study 2 also indicated that a multicultural message might be more effective if delivered in a culturally specific context, namely, after audience members watch a culturally specific video. Minimal changes were observed in distal outcome variables. It is argued that influencing proximate output variables is necessary, though not sufficient, for effecting long-term change in AIDS-related attitudes, beliefs, and behaviors.     

FDG-PET Analysis and Findings in Amnesia Resulting From Hypoxia

The assumptions underlying neuroimaging, and problems in its analysis and interpretation, are commonly underestimated in neuropsychology. The ways in which fluoro-deoxy-glucose (FDG) positron emission tomography (PET) data can be analysed are discussed. PET findings from four patients who had suffered severe amnesia, following episodes of acute hypoxia, are presented. These patients had shown evidence of medial temporal (hippocampal and parahippocampal) atrophy on MRI brain scans. The PET data were analysed in several different ways. The converging findings were that the patients showed bilateral thalamic hypometabolism, and there was also evidence of retrosplenial hypometabolism bilaterally. Cognitively, these patients performed most like other patients with medial temporal lesions, but the results indicate that structural lesions can have distal metabolic effects on structures elsewhere. These findings are interpreted in the light of neuroanatomical observations concerning parallel projections between medial temporal lobe structures and the thalamus, some of which pass via the retrosplenium.     

Australian lawyers' views on competency issues in older adults

Lawyers are often called upon by their older clients to draft contracts, make up wills or powers of attorney, or provide other forms of legal advice or service. With the increasing numbers of older people in the population, the numbers of older clients for legal practitioners is likely to increase. Older people are also at increased risk for impaired cognitive processes that can affect their ability to make reasoned judgements in civil contracts and other legal arrangements. Here we report on the results of a survey of 302 Australian solicitors as to their experience and practices in determining the capacity of older clients to make legal decisions. The responses, reflecting a 20.7% return rate, showed a wide range of experience in conducting capacity assessments, with a mean of 15.7 years (SD = 10.59). There was a very wide range of practices in determining capacity with no consensus. The most frequent form of questions older clients were asked related to personal and family history. Less than one-quarter asked for the rationale of the decision: the most appropriate form of question in the literature. The results suggest a need for further training of solicitors in the assessment of the capacity of older clients to make legal decisions.     

Health-Related Quality of Life in a Low-Socioeconomic Status Public Rental-Flat Population in Singapore

Health-related quality of life (HRQoL) is a well-established measure of health and general well-being. Socioeconomic status (SES) can affect HRQoL. We sought to determine whether there were differences in HRQoL between low versus higher area-SES flat communities in Singapore. Residents in two integrated public housing precincts comprising of rental-flat blocks (low area-SES neighborhood) and neighboring owner-occupied blocks (higher area-SES neighborhood) were asked to rate their self-perceived HRQoL using the EuroQol Group five dimensions (EQ-5D) instrument. The EQ-5D assesses HRQoL in five domains (mobility, self-care, usual activities, anxiety/mood and pain) and with a global visual analogue scale (EQ-VAS). We evaluated differences in HRQoL between the rental and owner-occupied neighborhoods, and factors associated with anxiety/depression in the rental-flat neighborhood using multivariate logistic regression. The participation rate was 89.1% (634/711). In the owner-occupied neighborhood, 56.7% (216/381) were in full health, compared with 54.2% (137/253) in the rental-flat population (OR = 0.90, 95%CI = 0.66–1.24, p = 0.568). Across the five domains, staying in a rental-flat neighborhood was independently associated with anxiety/depression (adjusted odds ratio [aOR] = 1.79, 95%CI = 1.10–2.92, p = 0.019). In the rental-flat population, having anxiety/depression was independently associated with minority ethnicity, problems with self –care, pain/discomfort, difficulty with healthcare costs, and not being on subsidized primary care (p < 0.05). There was no significant difference on the EQ-VAS between the two neighborhoods (p = 0.627). Staying in a low area-SES neighborhood was associated with more mental health problems. In the rental-flat population, self-reported anxiety/depression was associated with minority ethnicity, physical health problems, and financial disadvantage in healthcare.     

Automated respiratory sinus arrhythmia measurement: Demonstration using executive function assessment

Respiratory sinus arrhythmia (RSA) is a quantitative metric that reflects autonomic nervous system regulation and provides a physiological marker of attentional engagement that supports cognitive and affective regulatory processes. RSA can be added to executive function (EF) assessments with minimal participant burden because of the commercial availability of lightweight, wearable electrocardiogram (ECG) sensors. However, the inclusion of RSA data in large data collection efforts has been hindered by the time-intensive processing of RSA. In this study we evaluated the performance of an automated RSA-scoring method in the context of an EF study in preschool-aged children. The absolute differences in RSA across both scoring methods were small (mean RSA differences = –0.02–0.10), with little to no evidence of bias for the automated relative to the hand-scoring approach. Moreover, the relative rank-ordering of RSA across both scoring methods was strong (rs = .96–.99). Reliable changes in RSA from baseline to the EF task were highly similar across both scoring methods (96%–100% absolute agreement; Kappa = .83–1.0). On the basis of these findings, the automated RSA algorithm appears to be a suitable substitute for hand-scoring in the context of EF assessment.     

Self-injurious behavior: gene-brain-behavior relationships

This paper summarizes a conference held at the National Institute of Child Health and Human Development on December 6-7, 1999, on self-injurious behavior [SIB] in developmental disabilities. Twenty-six of the top researchers in the U.S. from this field representing 13 different disciplines discussed environmental mechanisms, epidemiology, behavioral and pharmacological intervention strategies, neurochemical substrates, genetic syndromes in which SIB is a prominent behavioral phenotype, neurobiological and neurodevelopmental factors affecting SIB in humans as well as a variety of animal models of SIB. Findings over the last decade, especially new discoveries since 1995, were emphasized. SIB is a rapidly growing area of scientific interest to both basic and applied researchers. In many respects it is a model for the study of gene-brain-behavior relationships in developmental disabilities.     

Does Duration of Deregulated Religious Markets Affect Church Attendance? Evidence from 26 Religious Markets in Europe and North America Between 1981 and 2006

This study tests the deregulation hypothesis of religious market theory in 26 European and Northern American countries by examining differences in religious involvement between and within countries. The deregulation hypothesis, which is assumed to be universally valid, predicts that religious involvement is higher in deregulated religious markets. Moreover, countries having deregulated religious markets for a longer period of time are supposed to have higher levels of involvement. Therefore, we test the duration hypothesis. This test is important, as it also has been argued that it may take time for deregulation to have an effect on religious involvement. Multilevel analysis on the stacked European and World Value Surveys of 1981, 1990, 2000, and 2006 show that deregulation fosters church attendance, but duration of deregulation does not increase church attendance. Although the deregulation hypothesis cannot be rejected, we find that modernization corrodes church attendance to a larger extent than deregulation can stimulate church attendance.     

Friends with benefits: the evolved psychology of same- and opposite-sex friendship

During human evolution, men and women faced distinct adaptive problems, including pregnancy, hunting, childcare, and warfare. Due to these sex-linked adaptive problems, natural selection would have favored psychological mechanisms that oriented men and women toward forming friendships with individuals possessing characteristics valuable for solving these problems. The current study explored sex-differentiated friend preferences and the psychological design features of same- and opposite-sex friendship in two tasks. In Task 1, participants (N = 121) categorized their same-sex friends (SSFs) and opposite-sex friends (OSFs) according to the functions these friends serve in their lives. In Task 2, participants designed their ideal SSFs and OSFs using limited budgets that forced them to make trade-offs between the characteristics they desire in their friends. In Task 1, men, more than women, reported maintaining SSFs for functions related to athleticism and status enhancement and OSFs for mating opportunities. In Task 2, both sexes prioritized agreeableness and dependability in their ideal SSFs, but men prioritized physical attractiveness in their OSFs, whereas women prioritized economic resources and physical prowess. These findings suggest that friend preferences may have evolved to solve ancestrally sex-linked adaptive problems, and that opposite-sex friendship may directly or indirectly serve mating functions.
