There is growing interest in the role of psychosocial stress in health disparities. Identifying which social stressors are most important to community residents is critical for accurately incorporating stressor exposures into health research. Using a community‐academic partnered approach, we designed a multi‐community study across the five boroughs of New York City to characterize resident perceptions of key neighborhood stressors. We conducted 14 community focus groups; two to three in each borough, with one adolescent group and one Spanish‐speaking group per borough. We then used systematic content analysis and participant ranking data to describe prominent neighborhood stressors and identify dominant themes. Three inter‐related themes regarding the social and structural sources of stressful experiences were most commonly identified across neighborhoods: (1) physical disorder and perceived neglect, (2) harassment by police and perceived safety and (3) gentrification and racial discrimination. Our findings suggest that multiple sources of distress, including social, political, physical and economic factors, should be considered when investigating health effects of community stressor exposures and psychological distress. Community expertise is essential for comprehensively characterizing the range of neighborhood stressors that may be implicated in psychosocial exposure pathways.  相似文献

We sought to document that the extent to which different ethnic groups are perceived as embodying the American identity is more strongly linked to antiminority policy attitudes and acculturation ideologies among majority‐group members (European Americans) than among minority‐group members (Asian Americans or Latino/as). Participants rated 13 attributes of the American identity as they pertain to different ethnic groups and reported their endorsement of policy attitudes and acculturation ideologies. We found a relative consensus across ethnic groups regarding defining components of the American identity. However, European Americans were perceived as more prototypical of this American identity than ethnic minorities, especially by European American raters. Moreover, for European Americans but not for ethnic minorities, relative ingroup prototypicality was related to antiminority policy attitudes and acculturation ideologies. These findings suggest that for European Americans, perceptions of ethnic group prototypicality fulfill an instrumental function linked to preserving their group interests and limiting the rights afforded to ethnic minorities.  相似文献

Groups 4 Health (G4H) is a group psychotherapy program that targets social group disconnection. An emerging evidence base supports its efficacy in reducing loneliness, depression, and social anxiety. However, to date there has been no formal analysis of its acceptability to clients and therapists, nor an investigation of its feasibility for wider implementation. This input from end users is crucial to ensure the program’s wider suitability and to contribute to its improvement. This study drew data from three clinical trials, including 266 G4H clients and 68 G4H therapists. From the Phase III trial only, additional data were available from 90 clients in a dose-controlled cognitive-behavioral therapy (CBT) comparison group, and focus groups/interviews with 6 therapists and 13 clients. Client satisfaction was high, with all average ratings >7/10, significantly exceeding the CBT comparison group. Therapist satisfaction with each module was >5/7. Retention was >80%. Homework completion was high, with <10% of clients saying that they had not attempted the homework. Therapists and clients both emphasized the benefits arising from G4H, and the contribution of the group context itself as a vehicle to achieve positive outcomes.  相似文献

Generalized anxiety disorder (GAD) is a common and debilitating condition. Effective treatments exist, but they are time- and resource-intensive. This study tested the initial efficacy and acceptability of a novel treatment protocol designed to increase efficiency: acceptance and commitment therapy (ACT) taught in groups and through an adjunctive mobile app. Participants were 21 individuals with GAD who received six weeks of 2-hour group ACT sessions as well as access to an adjunctive ACT mobile app. Significant improvements occurred in worry, anxiety, social functioning, and depression as well as relevant processes (psychological inflexibility, anxiety-related cognitive fusion). In-the-moment improvements were also observed in symptoms and ACT processes immediately after completing mobile app sessions. Treatment was perceived as credible and acceptable overall. However, rates of reliable and clinically significant change were low, and app usage did not correlate with change in worry. Overall, this study suggests that an efficient, brief ACT group intervention combined with a mobile app may lead to improvements in GAD but may not be sufficient for clinically significant change. A detailed overview of the treatment is included, and guidance for clinicians interested in implementing this protocol is discussed.  相似文献

集体自恋是将自恋延伸到群体水平的一个经典构念, 目前被界定为对于“自身所属群体是卓越的并值得优待, 却未充分被他者承认”的信念。现有研究发现它对群际敌对性有较强解释力, 因为集体自恋者对内群体形象、地位或身份所受威胁高度敏感, 容易高估威胁和怀疑外群体, 而缺乏自我价值感及控制感是集体自恋的重要根源。鉴于现有研究一般都预设了集体自恋的脆弱性和消极性, 而集体自恋的属性不必然如此, 未来研究应在充分厘清集体自恋内涵及结构的基础上探索其消极与积极后效, 揭示其多元成因及干预方法, 并推进跨文化研究。  相似文献

IntroductionAssuming that motivation is the key to initiate and sustain beneficial health behaviors, the aim of this systematic review was to analyze the effects of school-based physical activity interventions on a variety of motivational outcomes towards PA in school-aged children and adolescents.MethodsA comprehensive literature search was carried out in six electronic databases to identify randomized controlled trials and quasi-experimental trials examining the effects of PA interventions implemented during the regular school day, e.g., during physical education lessons or lunch breaks. Primary outcomes of interest were students' motivation, basic psychological needs, goal orientation, enjoyment, and motivational teaching climate in physical education. Meta-analyses were conducted for these outcomes using Comprehensive Meta-analysis software. Secondarily, intervention effects on students' PA behaviors were examined and the findings summarized narratively. Methodological quality of studies was evaluated using the Cochrane Collaboration's tool for assessing risk of bias for randomized trials; certainty of evidence on outcome level was evaluated using the GRADE approach.ResultsIn total, 57 studies carried out between 2001 and 2018 were included in this review. Sixteen individual meta-analyses were performed and revealed significant pooled effects for the outcomes enjoyment (g = 0.310), perceived autonomy (g = 0.152), identified regulation (g = 0.378), intrinsic motivation (g = 0.419), self-determination index (g = 0.672), task/mastery climate (g = 0.254), ego/performance climate (g = −0.438), autonomy supportive climate (g = 0.262), task goal orientation (g = 1.370), ego goal orientation (g = −0.188). The narrative data synthesis indicated an increase in students' PA behavior. The overall risk of bias was high across all studies and certainty of evidence of meta-analyzed outcomes ranged from very low to moderate. Moderate certainty of evidence was found for ego/performance climate and ego goal orientation. Conclusions: Meta-analyses suggest that school-based PA interventions may be effective in increasing a variety of motivational outcomes. However, the certainty of evidence was limited in the majority of outcomes. Further research is needed to identify effective intervention strategies that increase students’ motivation towards PA.  相似文献

Teachers play a pivotal role in the educational discourse around collective narratives, and especially the other's narrative. The study assumed that members of groups entangled in a conflict approach the different modules of the other's narrative distinctively. Jewish and Palestinian teachers, Israeli citizens, answered questionnaires dealing with the narrative of the other, readiness for interethnic contact, negative between‐group emotions and preferences for resolutions of the Israeli–Palestinian (I–P) conflict. Positive weighing of the other's narrative among Jewish teachers correlated with high levels of readiness for interethnic contact and low levels of negative between‐group emotions, across the various modules of the Palestinian narrative. Preferences for a peaceful resolution of the I–P conflict and rejection of a violent one were noted in two of the modules. Among Palestinian teachers, positive weighing of the other's collective narrative was exclusively noted for the Israeli narrative of the Holocaust, and this stance negatively related to negative between‐group emotions and preference for a violent solution of the I–P conflict, and positively related to readiness for interethnic contact and preference of a peaceful resolution of the conflict. Practical implications of these findings for peace education are discussed.  相似文献

The Good Behavior Game (GBG) is a classwide group contingency shown to reduce disruptive student behavior. We examined the feasibility of training young students to lead the GBG in one first‐grade and three kindergarten classes. We also examined teacher preference for teacher‐led GBG, student‐led GBG, or no GBG using a concurrent chains procedure. We successfully trained students in all classes to lead the GBG, and the GBG reduced disruptive behavior regardless of who implemented it. Preference for who implemented the game varied across teachers. Results of this study suggest that students as young as kindergarten age can be trained to implement the GBG and that teacher preference should be taken into account when determining how classwide interventions are to be implemented.  相似文献

Few interventions focus on teaching social skills to adolescents with autism spectrum disorder (ASD) and intellectual disabilities (ID) that are consistently used during interactions with peers ( Carter et al., 2014). The present study evaluated the effects of video‐based group instruction (VGI) on the acquisition of social perception skills of five adolescents with ASD or ID in a public school setting. Social perception involves observing affective behaviors of others, discriminating relevant environmental stimuli, and differentially reinforcing the affective behavior of another person. Typically developing peers supported VGI implementation as social partners for participants. A multiple probe design across behaviors demonstrated the effectiveness of VGI for teaching social perception skills. Four of five participants acquired and maintained the targeted social perception skills, and we observed some transfer to a nontreatment setting. Results of this study suggest VGI may support the acquisition of social perception among adolescents with ASD or ID.  相似文献
