Research has shown that neighborhoods play a role in the etiology of violence. However, few adolescent relationship aggression (ARA) studies have objective measures of violent neighborhoods. Drawing on a nationally representative sample of youth, this study examines the association between ARA and local levels of violent crime (measured using geocoded Uniform Crime Report data from each of the youths’ residential neighborhoods). Study analyses are based on survey data from 723 youth (ages 10–18) in current or recent dating relationships (351 males and 372 females) in the Survey on Teen Relationships and Intimate Violence (STRiV), a national representative household panel survey exploring interpersonal violence and related aggression among adolescents. About 19% of the sample reported ARA victimization in their most recent dating relationship (ARA perpetration was 17%). Neighborhood violent crime in the study (males living in 86.9 and females 99.8) was slightly lower than the national average of 100. With a broad national sample, 40% non-Whites, hypotheses guided by theories of neighborhood influence were tested. The study did not find an association between neighborhood violent crime and ARA victimization and perpetration, controlling for key demographic factors. The results, for a broad range of high- and low-crime neighborhoods, suggest that neighborhood violence does not seem to affect individual rates of ARA. The results suggest the ARA victimization and perpetration are perhaps ubiquitous and found both in low and high violent crime neighborhoods, suggesting that addressing local violent crime rates alone does not seem to be a path to also reducing ARA.  相似文献

Penile plethysmography (PPG) is an objective measure of male sexual arousal in response to the presentation of a series of erotic and neutral stimuli. This measure is now widely recognized as the most reliable means of objectively measuring male sexual arousal to specific stimuli. Many clinicians and researchers consider PPG to be a vital contribution to the assessment and treatment of adult men with paraphilic interests and men who have committed sex crimes. PPG contributes to the clinical assessment of paraphilic interests, appraisal of risk of recidivism, and provides an objective measurement of changes in sexual arousal in response to treatment. There is strong support for the utility of PPG within clinical and legal contexts. This article addresses ways in which PPG has been utilized in the courts as part of expert clinical opinion. History of its use, details regarding admissibility in court, and case law are explored within the legal systems of Canada, the UK and the USA. Support for the inclusion of PPG as expert evidence is provided and judicial misunderstandings on the rationale for PPG use and its clinical utility in forensic assessments are discussed.  相似文献

The purpose of this content analysis was to illustrate trends related to the use of the term adverse childhood experiences (ACEs), or terms related to the 10 components of ACEs, within 140 peer-reviewed articles published in 22 journals affiliated with the American Counseling Association (ACA) and the American School Counselor Association (ASCA) between 1998 and 2018. Of the 9,120 articles published in the 22 ACA- and ASCA-affiliated journals in that time, only three articles (0.03%) explicitly mentioned the term adverse childhood experiences in the title, abstract, or keywords. Authors of 93 journal articles mentioned terms related to the original 10 categories of ACEs 104 times (1.0% of all published articles). The need for consistent language across research and practice is highlighted. Implications include ways that the counseling field may benefit from an increased clarity and focus around ACEs.  相似文献

This study assessed change in self-reported Big Five personality traits. We conducted a coordinated integrative data analysis using data from 16 longitudinal samples, comprising a total sample of over 60 000 participants. We coordinated models across multiple datasets and fit identical multi-level growth models to assess and compare the extent of trait change over time. Quadratic change was assessed in a subset of samples with four or more measurement occasions. Across studies, the linear trajectory models revealed declines in conscientiousness, extraversion, and openness. Non-linear models suggested late-life increases in neuroticism. Meta-analytic summaries indicated that the fixed effects of personality change are somewhat heterogeneous and that the variability in trait change is partially explained by sample age, country of origin, and personality measurement method. We also found mixed evidence for predictors of change, specifically for sex and baseline age. This study demonstrates the importance of coordinated conceptual replications for accelerating the accumulation of robust and reliable findings in the lifespan developmental psychological sciences. © 2020 European Association of Personality Psychology  相似文献

ABSTRACT

Active duty military service members endure a unique constellation of stressors while deployed or at home. Yet, assessment of protective factors against these stressors among active duty service members represents an under studied area. The present study advances the assessment of protective factors through the psychometric evaluation of the Coping Self-Efficacy Scale (CSES) in a clinical sample of military service members in mental health or substance abuse treatment (n = 200). Cross-sectional data were drawn from military medical records and a supplemental self-report questionnaire. Data extracted included demographic (e.g., sex, age), military characteristics (e.g., rank, years in service), physical health and mental health (e.g., anxiety, depression), and coping self-efficacy. Findings suggest a 3-factor (i.e., problem-focused coping, thought-stopping, and getting social support) CSES structure with acceptable internal consistency. Further, there were small-to-moderate associations with physical and mental health outcomes, providing evidence of construct validity. There were few significant associations with military-related characteristics. Finally, controlling for covariates, thought-stopping beliefs explained unique variance in suicide-related behaviors. Together, findings support the use of the CSES to measure coping-related beliefs in military service members. Recommendations are offered for future research and practice with active duty service members.  相似文献

Matrix training is a teaching strategy designed to facilitate generative responding through a process termed recombinative generalization. A skill that has yet to be addressed with matrix training is tacting time increments. Given the two‐component features of time telling (i.e., hours and minutes) and the numerous teaching targets, matrix training was implemented for such behavior with two adults with developmental disabilities. This study used a 12 × 12 matrix that consisted of 144 time increments. Participants were taught 12 time increments, and probes were conducted to assess the remaining 132 untrained time increments. The participants responded correctly to approximately 50% of the untrained time increments during the post‐assessment phase. Limitations and future research are discussed.  相似文献

English‐monolingual children develop a shape bias early in language acquisition, such that they more often generalize a novel label based on shape than other features. Spanish‐monolingual children, however, do not show this bias to the same extent (Hahn & Cantrell, 2012). Studying children who are simultaneously learning both Spanish and English presents a unique opportunity to further investigate how this word‐learning bias develops. Thus, we asked how Spanish–English bilingual children (Mage = 21.31 months) perform in a novel‐noun generalization (NNG) task, specifically examining how past language experience (i.e. language exposure and vocabulary size) and present language context (i.e. whether the NNG task was conducted in Spanish or English) influence the strength of the shape bias. Participants completed the NNG task either entirely in English (N = 16) or entirely in Spanish (N = 16), as well as language understanding tasks in both English and Spanish to ensure that they understood what the experimenter was asking them to do. Parents completed a language exposure survey and vocabulary checklists in Spanish and English. There was a significant interaction between condition and choice type: Bilingual children in the English condition showed a shape bias in the NNG task, but bilingual children in the Spanish condition showed no reliable biases. No measures of past language experience were related to NNG task performance. These results suggest that when learning new words, bilingual children are attuned to the regularities of the present language context, and prior language experiences may play a more secondary role.  相似文献

There is a fair amount of support for the premise that parents construct their child-related values from the ethnic cultural models that are available to them. There are also indications that personal experiences play a role in the construction of values. However, this latter influence has not been well-researched. We reconstructed the child-related values of a sample of Mexican American and Puerto Rican parents of young children with disability to describe parent-held values and to examine the extent to which having a child with a disability impacted on these values. Analysis of parental ratings and of their narratives indicated substantial consistency across gender, civil status, and country of origin. Disability appeared to have a small and diffused impact on the values. Ratings differed significantly on the basis of the language of interview, and the definitions that parents offered also showed an effect of interaction with the Anglo American culture. However, an in-depth examination of these differences indicated that they were mostly restricted to labeling. The basic values of parents remained fairly consistent. This finding has substantial implications for research and practice. Equivalence of meaning should not be assumed across populations.  相似文献
