There is growing evidence that psychopathic traits are stable across the adolescent developmental period. Yet, no previous studies have examined the longitudinal course of these traits across adolescence. In this study, we examined joint developmental trajectories of grandiose-manipulative traits, callous-unemotional traits, and impulsive-irresponsible behavior and how these trajectories were related to changes in parental behavior and delinquency over time. Participants were 1,068 adolescents from a community sample, who were followed annually over 4 years. Overall, our results showed that a four-class latent class growth model best represented the developmental pattern of adolescent psychopathic traits. Although the majority of adolescents showed low or moderate initial levels that also decreased over time, there was a small group of adolescents who, despite significant decreases in two out of three dimensions, still maintained relatively high levels on all three dimensions. We also found that parental behavior and delinquency developed differently for the groups over time, with the high-decreasing group engaging in more delinquent behavior over time and experiencing more negative parental behavior than any other group. In sum, our findings suggest that there is a group of adolescents at particular risk for negative development.  相似文献

Two different types of ruminative coping, depressive rumination and grief rumination, negatively influence bereavement outcome. Although grief-specific rumination is likely to be relevant in the bereavement context no internationally validated scale to measure grief rumination exists. Therefore, the current contribution aims to validate the Utrecht Grief Rumination Scale (UGRS), a scale developed to measure grief-specific rumination, in an English sample. Psychometric properties of the English UGRS were compared with those in a Dutch sample. 204 British adults (89 % women, 11 % men), bereaved on average 16 months ago, and 316 Dutch adults (88 % women, 12 % men), bereaved on average 12 months ago, filled out online questionnaires. Different types of rumination (grief rumination, brooding, reflection, trait rumination) and symptoms of psychopathology (anxiety, depression, complicated grief) were measured. A correlated five factor model provided the best fit for the UGRS. Multi-group comparisons showed that the factor structures of the English and Dutch version of the UGRS were highly similar across language groups. The UGRS showed excellent reliability. Results further supported the construct, convergent, divergent and concurrent validity of the English UGRS. The psychometric properties of the Dutch UGRS corroborated these findings. The UGRS appears a valid instrument to assess grief-specific rumination in international research and may have potential applicability as a clinical instrument to assess rumination in individuals with problematic grief.  相似文献

Abstract: The common practice of giving (comparing, rejecting and inferring) explanations of phenomena is at the root of articulate learning, including the enterprises we collect under the noun ‘science’. The way that practice privileges a single item from the myriad relevant to any phenomenon tells us something about articulateness itself.  相似文献

Until relatively recently, most psychologists have had limited professional involvement with older adults. With the baby boomers starting to turn 65 years old in 2011, sheer numbers of older adults will continue to increase. About 1 in 5 older adults has a mental disorder, such as dementia. Their needs for mental and behavioral health services are not now adequately met, and the decade ahead will require an approximate doubling of the current level of psychologists' time with older adults. Public policy in the coming decade will face tensions between cost containment and facilitation of integrated models of care. Most older adults who access mental health services do so in primary care settings, where interdisciplinary, collaborative models of care have been found to be quite effective. To meet the needs of the aging population, psychologists need to increase awareness of competencies for geropsychology practice and knowledge regarding dementia diagnosis, screening, and services. Opportunities for psychological practice are anticipated to grow in primary care, dementia and family caregiving services, decision-making-capacity evaluation, and end-of-life care. Aging is an aspect of diversity that can be integrated into psychology education across levels of training. Policy advocacy for geropsychology clinical services, education, and research remains critical. Psychologists have much to offer an aging society.  相似文献

Previous research has developed multiple indices to detect instances of insufficient effort responding (IER; Huang et al., 2015, 0.1037/a0038510). Although these techniques are largely successful, conflation between effort and insufficient effort leads to unnecessary data removal, thus warranting investigation into IER prevention strategies such as warning statements. For example, Brühlmann et al. (2020, 10.1016/j.metip.2020.100022) reported that close to 60% of participants were flagged for IER on at least one IER detection index. The current study used positive, negative, and no warning statements in two samples (MTurk and university participant pool) to examine their impact on two types of IER. Results do not support the use of warning statements to reduce IER covertly, overtly, or overall. Although slightly more university participants were flagged for IER for two of five IER indices, the remaining three indices did not differ between samples. This finding represents an important contribution to survey research literature by directly comparing samples on a variety of IER indices. Implications for survey research necessitate the examination of additional prevention strategies and sample differences in IER.  相似文献

This study included 212 women and 38 men students from nine women's studies classes and 101 women and 35 men from nine non-women's studies classes. At pretesting and posttesting students completed the Performance Self-Esteem Scale (PSES) and measures of their educational and job certainty and motivation. Comparison students were similar to women's studies students in having a woman teacher and having an interest in the women's studies curriculum. At posttesting women's studies students showed greater gains in PSES scores ( p < .01) and in job motivation and job certainty ( p < .01) than did the comparison students. The results support the value of women's studies for men as well as women students.  相似文献

This article explores affect, colonial privilege, and the cultural politics of national commemoration in Aotearoa New Zealand. Based on focus-group interviews around two major national days, we examine means through which feelings and emotions are deployed in ways that enable the reproduction of social advantage. Situating affect within patterns of relationship, four interrelated affective-discursive practices are explored. In relation to Waitangi Day, agents tend to work under the rubric of anger and confusion. For Anzac Day, being grateful and moved shapes the interaction, although participants often indicate preferences towards “having a day off.” Given the colonial context in which these practices circulate, analysis observes the associated freedom and ease by which affective-discursive privilege is (re)produced. Often incongruent and rarely challenged, privilege allows associated actors to do what they want, when they want, however they want. This affective climate authorizes the ongoing reproduction of, and justification for, membership to a higher-status ethnic group of which unearned opportunities and entitlements remain its everyday, expected currency.  相似文献

Over the past decade, US states have responded to federal inaction on comprehensive immigration reform by increasing their output of immigrant policies, both beneficial and restrictive. Although there is a growing empirical literature focused on predicting such activity by states, less is known, especially on a broad scale, about the state-level consequences associated with the policy tone states adopt toward immigrants. To better understand the consequences of restrictive immigrant policies, we created a restrictive score for each state year between 2005 and 2014 and employed linear regression with panel-corrected standard errors to investigate effects on immigrant-related demographics, economic factors, and political participation. We found that states with higher restrictive policy tones do experience reductions in the number of foreign-born residents, including Hispanics and those with limited English proficiency, a goal of many state legislators who favor restrictive policies. States with restrictive policy tones showed reductions in unemployment and poverty rates as well, which are also professed goals for restrictive policy activity. Mediation analyses suggested that the effects of restrictive policy scores on economic conditions are indirect, being exerted through the percentage of a state’s population that is foreign born. Finally, though much attention is focused on the expected increase in Latino political clout, restrictive policy tone was not predictive of increased voter registration or voting in states that pass these types of policies. If anti-immigrant policies are inducing those who oppose these policies to mobilize politically, it must be in an arena outside of voting.  相似文献
