Objectives

Projection effects have been shown to bias respondent perceptions of peer delinquency, but network data required to measure peer delinquency directly are unavailable in most existing datasets. Some researchers have therefore attempted to adjust perceived peer behavior measures for bias via latent variable modeling techniques. The present study tested whether such adjustments render perceived peer coefficients equal to direct peer coefficients, using original data collected from 538 young adults (269 dyads).

Methods

After first replicating projection effects in our own data and examining the degree to which measures of personal, perceived peer, and direct peer violence represent empirically distinct constructs, we compared coefficients derived from two alternative models of personal violence. The first model included an error-adjusted latent measure of perceived peer violence as a predictor, whereas the second substituted a latent measure of directly-assessed, peer-reported violence.

Results

Results suggest that personal, perceived peer, and direct peer measures each reflect fundamentally separate constructs, but call into question whether latent variable techniques used by prior researchers to correct for respondent bias are capable of rendering perceived peer coefficients equal to direct peer coefficients.

Conclusions

Research cannot bypass the collection of direct peer delinquency measures via latent variable modeling adjustments to perceived peer measures, nor should models of deviance view perceived peer and direct peer measures as alternative measures of the same underlying construct. Rather, theories of peer influence should elaborate and test models that simultaneously include both peer measures and, further, should attempt to identify those factors that account for currently unexplained variance in perceptions of peer behavior.  相似文献

This study examined relations among stressors, perceived social competence, attributional style, and depressive symptoms in young urban schoolchildren. Data were collected from 85 5- to 11-year-olds, mostly African American, who attended a public elementary school in a low-income urban area. Social competence was examined as a potential mediator, and attributional style was examined as a potential moderator of the relation between stressful life events and depressive symptoms. Separate analyses were conducted by age and gender. For older children and girls, main effects were found for stressful life events as predictors of depressive symptoms. Mediational analyses indicated that perceived peer acceptance served as a mediator of the relation between stressful life events and depressive symptoms for girls. In addition, attributional style moderated the relation between stressors and depressive symptoms in the older children. Together, findings suggest that significant relations exist among stressful life events, social and cognitive processes, and depressive symptoms in young urban children and that these relations are influenced by gender and development.  相似文献

Psychopathic traits are associated with violent, aggressive behaviors and recidivism in adulthood. To increase positive treatment outcomes, it is arguably beneficial to identify and treat psychopathy as early as possible. Furthermore, because research shows that the effectiveness of behavior modification is likely to be affected by the social information-processing patterns of aggressive children, it is important to understand the relationship between conduct-disordered traits and social cognitions. The results of this study showed that callous/unemotional traits in a community-based sample of behavior-disordered youth (57 male, 19 female; 10-19 years of age; 63% African American) significantly predicted values in obtaining a tangible reward and getting into trouble or being punished. However, callous/unemotional traits, impulsivity/conduct problems, and narcissism failed to predict positive expectations regarding receiving a tangible reward, reducing aversive treatment, and demonstration of dominance. Implications for these results are presented.  相似文献

Indicator systems to report on concepts such as sustainability and progress have become a key policy response by governments to concerns over environmental degradation and social and economic instability. When developed by a national bureau, public service imperatives suggest that concepts such as ‘sustainability’ and ‘progress’ should be addressed without offending the ideology of political actors. We offer a case study of the Australian Bureau of Statistics (ABS) Measures of Australia's Progress (MAP) indicator system. The ABS has chosen to avoid offering a clear definition of what progress means, or a conceptual framework linked to a definition to explain the selection of indicators. ‘Progress’, however, is a socially defined, normative concept. Such concepts cannot be understood without reference to cultural and political processes. By seeking to avoid a perception of cultural or political bias the ABS has limited MAP's capacity to measure progress. We conclude with suggestions on how MAP might be improved.  相似文献

In recent years, there has been increased research focus on dating violence, producing important information for reducing these violent relationships. Yet Institutional Review Boards (IRBs) are often hesitant to approve research on dating violence, citing emotional distress of participants as a possible risk of participation. However, no known research has examined the reactions of research participants to questions about dating violence. The current study examined the reactions among college students to completing a self-report measure on dating violence. Results showed that participants reported numerous positive experiences as a result of their research participation, with only mildly increased negative emotional reactions evident for some. Findings are discussed in relation to IRB proposals and appropriate informed consent for research participants.  相似文献

The present study investigates how visitation from parents impacts youths’ mental health in the first two months of incarceration in a secure juvenile facility. A diverse sample of 276 male, newly incarcerated serious adolescent offenders (14–17 years) was interviewed over a 60-day period. Results indicate that youth who receive visits from parents report more rapid declines in depressive symptoms over time compared to youth who do not receive parental visits. Moreover, these effects are cumulative, such that the greater number of visits from parents, the greater the decrease in depressive symptoms. Importantly, the protective effect of receiving parental visits during incarceration exists regardless of the quality of the parent–adolescent relationship. Policy changes that facilitate visitation may be key for easing adjustment during the initial period of incarceration.  相似文献
