The authors investigated prospectively assessed eating pathology (body image dissatisfaction and bulimia nervosa symptoms) among an ethnically and socioeconomically diverse sample of adolescent girls with attention-deficit/hyperactivity disorder-combined type (ADHD-C; n=93), ADHD-inattentive type (ADHD-I; n=47), and a comparison group (n=88). The sample, initially ages 6-12 years, participated in a 5-year longitudinal study (92% retention rate). After statistical control of relevant covariates, girls with ADHD-C at baseline showed more eating pathology at follow-up than did comparison girls; girls with ADHD-I were intermediate between these two groups. Baseline impulsivity symptoms, as opposed to hyperactivity and inattention, best predicted adolescent eating pathology. With statistical control of ADHD, baseline peer rejection and parent- child relationship problems also predicted adolescent eating pathology. The association between punitive parenting in childhood and pathological eating behaviors in adolescence was stronger for girls with ADHD than for comparison girls. Results are discussed in terms of the expansion of longitudinal research on ADHD to include female-relevant domains of impairment, such as eating pathology.  相似文献

DEBI, or the Diffusion of Effective Behavioral Interventions is the largest centralized effort to diffuse evidence-based prevention science to fight HIV/AIDS in the United States. DEBI seeks to ensure that the most effective science-based prevention interventions are widely implemented across the country in community-based organizations. Thus, this is a particularly timely juncture in which to critically reflect on the extent to which known principles of community collaboration have guided key processes associated with the DEBI rollout. We review the available evidence on how the dissemination of packaged interventions is necessary but not sufficient for ensuring the success of technology transfer. We consider additional principles that are vital for successful technology transfer, which were not central considerations in the rollout of the DEBI initiative. These issues are: (1) community perceptions of a top-down mode of dissemination; (2) the extent to which local innovations are being embraced, bolstered, or eliminated; and (3) contextual and methodological considerations that shape community preparedness. Consideration of these additional factors is necessary in order to effectively document, manage, and advance the science of dissemination and technology transfer in centralized prevention efforts within and outside of HIV/AIDS.  相似文献

Individuals with autism exhibit significant impairments in prosody production, yet there is a paucity of research on prosody comprehension in this population. The current study adapted a psycholinguistic paradigm to examine whether individuals with autism are able to use prosody to resolve syntactically ambiguous sentences. Participants were 21 adolescents with high-functioning autism (HFA), and 22 typically developing controls matched on age, IQ, receptive language, and gender. The HFA group was significantly less likely to use prosody to disambiguate syntax, but scored comparably to controls when syntax alone or both prosody and syntax indicated the correct response. These findings indicate that adolescents with HFA have difficulty using prosody to disambiguate syntax in comparison to typically developing controls, even when matched on chronological age, IQ, and receptive language. The implications of these findings for how individuals with autism process language are discussed.  相似文献

The paucity of investigative studies exploring the coming out process of families was the impetus for this case study with a six member family-of-choice. In-depth interviews highlight the complexities of negotiating family rules, journey with the family as they struggled with their new identity, and reveal how the reflexive process contributed to the family’s co-creation of new stories. The four themes that emerged (embracing gay identity, integrating as a family, building social networks, and social awakening), offer details of how the family reconfigured from the rubble of confusion to become more cohesive, awakened and empowered. Implications for clinical practice with families with gay members are addressed.  相似文献

Previous studies using an in vitro model of eyeblink classical conditioning in turtles suggest that increased numbers of synaptic AMPARs supports the acquisition and expression of conditioned responses (CRs). Brain-derived neurotrophic factor (BDNF) and its associated receptor tyrosine kinase, TrkB, is also required for acquisition of CRs. Bath application of BDNF alone induces synaptic delivery of GluR1- and GluR4-containing AMPARs that is blocked by coapplication of the receptor tyrosine kinase inhibitor K252a. The molecular mechanisms involved in BDNF-induced AMPAR trafficking remain largely unknown. The aim of this study was to determine whether BDNF-induced synaptic AMPAR incorporation utilizes similar cellular mechanisms as AMPAR trafficking that occurs during in vitro classical conditioning. Using pharmacological blockade and confocal imaging, the results show that synaptic delivery of GluR1 subunits during conditioning or BDNF application does not require activity of NMDARs but is mediated by extracellular signal-regulated kinase (ERK). In contrast, synaptic delivery of GluR4-containing AMPARs during both conditioning and BDNF application is NMDAR- as well as ERK-dependent. These findings indicate that BDNF application mimics AMPAR trafficking observed during conditioning by activation of some of the same intracellular signaling pathways and suggest that BDNF is a key signal transduction element in postsynaptic events that mediate conditioning.  相似文献

Risk factors for suicidal ideation and attempts have been shown to differ between African Americans and Whites across the lifespan. In the present study, risk factors for suicidality were examined separately by race/ethnicity in a population of 131 older adult patients considered vulnerable to suicide due to substance abuse and/or medical frailty. In adjusted analyses, social support was significantly associated with suicidality in African American patients, while younger age and the presence of an anxiety disorder were significantly associated with suicidality in White patients. The results suggest that race/ethnicity-specific risk profiles may improve the detection of suicidality in vulnerable populations.  相似文献

Previous studies have identified neuropsychological deficits in individuals with antisocial personality disorder and/or psychopathy. Few studies have examined neuropsychological functioning in individuals with borderline personality disorder (BPD), and no studies have yet investigated cognitive and emotional function in male prisoners with BPD. In this study, we compared the risky decision-making of 17 participants with a history of serious violent or sexual offenses and a diagnosis of DSM-IV BPD with that of 17 participants with similar offending histories but personality disorders other than BPD. Those with BPD exhibited altered processing of information about potential losses (punishment) when the probability of gains (reward) was high; they also increased their choice of risky options even in circumstances where this was clearly avoidable. These data suggest that individuals with a diagnosis of BPD and a history of serious offenses have problems integrating different reinforcement signals when choosing between risky actions, perhaps reflecting corticolimbic dysfunction as an underlying mechanism in BPD.  相似文献

The present study identifies a broad taxonomy of motives underlying the desire to regulate prejudice and assess the impact of motivation to regulate prejudice on levels of explicit and implicit prejudice. Using self-determination theory as the foundation, six forms of motivation to regulate prejudice are proposed. In Study 1 (N = 257), an exploratory factor analysis reveals evidence for the six proposed dimensions. In Study 2 (N = 198), the six-factor taxonomy of motivation to regulate prejudice is further validated using a confirmatory factor analysis, and construct validity is obtained. In Study 3 (N = 62), motivation to regulate prejudice is manipulated before participants complete the Implicit Association Test (IAT) and explicit measures of prejudice. Results reveal that those with highly self-determined regulation of prejudice demonstrate lower implicit and explicit prejudice than their less self-determined counterparts. Results are discussed in terms of an increased understanding of the motivation to control prejudice.  相似文献

Social organization of a species influences myriad facets of individuals’ behavior. Much research indicates that human social organization consists of males in large groups and females in smaller groups or interacting with individuals. This study analyzed the initial factors that produce greater preferences for groups by human male versus female infants. To this end, using a looking preference paradigm, fifty-nine 6–8-month-old infants viewed individual versus group images of actual children. On the basis of several controls, results demonstrated that male more than female infants are attracted to the complex level of stimulation provided by groups. Discussion centers on further identifying male versus female patterns of group interaction from a perceptual and cognitive standpoint.  相似文献

Workplace bullying in global organizations occurs for several reasons, including growing diversity, increased dispersion of employees in geographic locations, lack of experience of managers with new environments, and varying requirements. To gain insight into the bullying phenomenon, one must examine the characteristics of the bully, the target of bullying activities (e.g., the victim or the bullied), observers of the bullying (e.g., bystanders), and resulting changes in the organizational culture because of the bullying. One additional element to be assessed is the means by which bullying activities are embodied in an organization's culture (i.e., social/emotional contagion). This paper proposes a model of bullying in global organizations and examines the potential of social/emotional contagion developing in global organizations' cultures.  相似文献
