Intrusive parenting has been positively associated with child anxiety, although examinations of this relationship to date have been largely confined to middle to upper middle class families and have rarely used longitudinal designs. With several leading interventions for child anxiety emphasizing the reduction of parental intrusiveness, it is critical to determine whether the links between parental intrusiveness and child anxiety broadly apply to families of all financial means, and whether parental intrusiveness prospectively predicts the development of child anxiety. This study employed latent growth curve analysis to evaluate the interactive effects of maternal intrusiveness and financial means on the developmental trajectory of child anxiety from 1st grade to age 15 in 1,121 children (50.7 % male) and their parents from the NICHD SECCYD. The overall model was found to provide good fit, revealing that early maternal intrusiveness and financial means did not impact individual trajectories of change in child anxiety, which were stable from 1st to 5th grade, and then decrease from 5th grade to age 15. Cross-sectional analyses also examined whether family financial means moderated contemporaneous relationships between maternal intrusiveness and child anxiety in 3rd and 5th grades. The relationship between maternal intrusiveness and child anxiety was moderated by family financial means for 1st graders, with stronger links found among children of lower family financial means, but not for 3rd and 5th graders. Neither maternal intrusiveness nor financial means in 1st grade predicted subsequent changes in anxiety across childhood. Findings help elucidate for whom and when maternal intrusiveness has the greatest link with child anxiety and can inform targeted treatment efforts.  相似文献

At present, it is not clear whether the current definition of separation anxiety disorder (SAD) is the optimal classification of developmentally inappropriate, severe, and interfering separation anxiety in youth. Much remains to be learned about the relative contributions of individual SAD symptoms for informing diagnosis. Two-parameter logistic Item Response Theory analyses were conducted on the eight core SAD symptoms in an outpatient anxiety sample of treatment-seeking children (N?=?359, 59.3 % female, M Age?=?11.2) and their parents to determine the diagnostic utility of each of these symptoms. Analyses considered values of item threshold, which characterize the SAD severity level at which each symptom has a 50 % chance of being endorsed, and item discrimination, which characterize how well each symptom distinguishes individuals with higher and lower levels of SAD. Distress related to separation and fear of being alone without major attachment figures showed the strongest discrimination properties and the lowest thresholds for being endorsed. In contrast, worry about harm befalling attachment figures showed the poorest discrimination properties, and nightmares about separation showed the highest threshold for being endorsed. Distress related to separation demonstrated crossing differential item functioning associated with age—at lower separation anxiety levels excessive fear at separation was more likely to be endorsed for children ≥9 years, whereas at higher levels this symptom was more likely to be endorsed by children <9 years. Implications are discussed for optimizing the taxonomy of SAD in youth.  相似文献

In this article we explore how assumptions about human nature may influence the ways one might try to promote ethical behavior in organizations. We summarize two common views of human nature in organizational research—Homo economicus and Homo heuristicus. We then extend these views by putting forward a third view of human nature initially proposed by Emile Durkheim—Homo duplex—which describes human beings as moving back and forth between a lower (individual) and higher (collective) level. We suggest that the Homo duplex view is uniquely equipped to account for variables of interest to organizational scholars because of its attention to a fundamental tension: People in organizations can be both selfish and groupish, and the balance between those tendencies influences the ethical profile of the organization in complex ways. We end with a discussion of the theoretical implications of the Homo duplex view for behavioral ethics researchers.  相似文献

There is limited research into the realities of science blogging, how science bloggers themselves view their activity and what bloggers can achieve. The ‘badscience’ blogs analysed here show a number of interesting developments, with significant implications for understandings of science blogging and scientific cultures more broadly. A functioning and diverse online community (with offline elements) has been constructed, with a number of non-professional and anonymous members and with boundary work being used to establish a recognisable outgroup. The community has developed distinct norms alongside a type of distributed authority and has negotiated the authority, anonymity and varying status of many community members in some interesting and novel ways. Activist norms and initiatives have been actioned, with some prominent community campaigns and action. There are questions about what science blogging—both in the UK and internationally—may be able to achieve in future and about the fragility of the ‘badscience’ community. Some of the highly optimistic hopes which have been associated with science blogging have not been realised. Nonetheless, the small group of bloggers focused on here have produced significant achievements with limited resources, especially when one considers this in the context of community values as opposed to some of the expectations attached to science blogging within scientific cultures more broadly. While the impacts of this science blogging community remain uncertain, the novel and potentially significant practices analysed here do merit serious consideration.  相似文献

This paper explores household pre‐purchase practices and their mediation by information and communications technologies (ICTs), specifically online grocery shopping. Drawing on practice theory, the impacts of ICTs on household grocery shopping behavior are conceptualized, and the concept of “front‐loading” is introduced. Emerging themes generated from 31 semi‐structured interviews conducted via Skype with Turkish consumers focusing on their experiences of online grocery practices are presented. To this end, the contribution of this paper is twofold. First, an understanding of the domestication of online grocery shopping and its affect on the dynamics of household decision making, information sharing, and responsibilities of tasks before the actual act of online shopping is developed. Second, how such pre‐purchase practices undertaken by consumers act as a catalyst of change at the industry level is appraised. Copyright © 2014 John Wiley & Sons, Ltd.  相似文献

Processing multiple complex features to create cohesive representations of objects is an essential aspect of both the visual and auditory systems. It is currently unclear whether these processes are entirely modality specific or whether there are amodal processes that contribute to complex object processing in both vision and audition. We investigated this using a dual-stream target detection task in which two concurrent streams of novel visual or auditory stimuli were presented. We manipulated the degree to which each stream taxed processing conjunctions of complex features. In two experiments, we found that concurrent visual tasks that both taxed conjunctive processing strongly interfered with each other but that concurrent auditory and visual tasks that both taxed conjunctive processing did not. These results suggest that resources for processing conjunctions of complex features within vision and audition are modality specific.  相似文献

Standard written emotional disclosure (WED) about stress, which is private and unguided, yields small health benefits. The effect of providing individualized guidance to writers may enhance WED, but has not been tested. This trial of computer-based WED compared two novel therapist-guided forms of WED – advance guidance (before sessions) and real-time guidance (during sessions, through instant messaging) – to both standard WED and control writing; it also tested Big 5 personality traits as moderators of guided WED. Young adult participants (n = 163) with unresolved stressful experiences were randomized to conditions, had three, 30-min computer-based writing sessions, and were reassessed six weeks later. Contrary to hypotheses, real-time guidance WED had poorer outcomes than the other conditions on several measures, and advance guidance WED also showed some poorer outcomes. Moderator analyses revealed that participants with low baseline agreeableness, low extraversion, or high conscientiousness had relatively poor responses to guidance. We conclude that providing guidance for WED, especially in real-time, may interfere with emotional processing of unresolved stress, particularly for people whose personalities have poor fit with this interactive form of WED.  相似文献

The use of psychotropic medications in youth has significantly increased in recent years. Moreover, the use of multiple medications, or polypharmacy, has seen a corresponding increase. The use of medications is largely based on diagnostic impressions and the targeted symptom. However, due to the dearth of applied research with severely troubled youth, there is very little “evidence base” to guide this practice. The Survey of Adolescent Treatment Experience study surveyed youth, currently placed in residential care, on their impressions of medication effectiveness on a wide-range of symptom categories. Youth report only mediocre effectiveness in their medication across a range of symptom questions. Approximately one third of youth indicated that they felt positive about taking medications. On average, slightly less than 50 % of youth reported benefits from medications across symptom categories. It is argued that these findings should inform the efforts toward individualized treatment models.  相似文献
