The nature of aggressive boys' behaviour is examined. Pre-selected matched pairs of aggressive and control boys were observed in a naturalistic setting which facilitated comparison of the way in which recorded behaviours affected their respective peer relationships. A continuous commentary describing the child's interactions with others was recorded simultaneously with the child's speech during school play. These data were transcribed and coded according to activity, social participation, neighbours, and interactions. Individual behavioural items were grouped on the basis of their functional similarity. Marked differences were found between the two groups on certain categories, giving a clear indication of specific deficiencies in the behavioural repertoire of the aggressive boys. 相似文献

To evaluate how constant the form of agonistic interactions in the event of environmental changes is, a group of 11 stumptailed macaques, formed shortly before the start of the study, was observed under the following spatial conditions: in 10 and 18 m2 cages, and in a 50,000 m2 woodland. Results showed that the frequency of agonistic interactions was little affected by spatial density; however, the number of participants involved in aggressive interactions increased in the cage. Formal biting, which presumably acts as a regulator of social tension, was less frequent in the park. Patterning of agonistic interactions was little affected by spatial density. Such “robustness” makes the form of aggression liable to be used as a potentially useful parameter in interspecific comparisons. 相似文献

Be a Mom is a self-guided web-based intervention, grounded in cognitive behavioral therapy, delivered to postpartum women to prevent persistent postpartum depression [PPD] symptoms. We aimed to evaluate Be a Mom in terms of its preliminary efficacy, feasibility, and acceptability. A pilot randomized, two-arm controlled trial was conducted. Eligible women (presenting PPD risk-factors and/or early-onset PPD symptoms) were enrolled in the study and were randomly assigned to the intervention (Be a Mom) or to the waiting-list control group. Participants in both groups completed baseline (T1) and postintervention (T2) assessments. The 194 women presenting risk factors/early-onset PPD symptoms were allocated to the intervention (n = 98) or to the control (n = 96) group. A significant Time × Group interaction effect was found for both depressive and anxiety symptoms, with women in the intervention group presenting a larger decrease in symptoms from T1 to T2 (p < .05). Less than half of the women (41.8%) completed Be a Mom. Most women (71.4%) would use Be a Mom again if needed. Results provide preliminary evidence of the Be a Mom’s efficacy, acceptability and feasibility, although further research is needed to establish Be a Mom as a selective/indicative preventive intervention for persistent PPD. 相似文献

Three-generation households that include parents and grandparents raising children together have become increasingly common in China. This study examined the relations among depressive symptoms, parenting stress, and caregiver–child relationships in the mother–grandmother dyadic context. Participants were mothers and grandmothers from 136 three-generation households. Results from Actor–Partner Interdependence Mediation Modeling indicated that mothers’ depressive symptoms were indirectly related to mother–child conflict/closeness through own parenting stress; grandmothers’ depressive symptoms were indirectly related to grandmother–child conflict through own parenting stress. Mothers’ depressive symptoms were indirectly related to grandmothers’ conflict with children through grandmothers’ parenting stress, and grandmothers’ depressive symptoms were indirectly related to mothers’ conflict/closeness with children through mothers’ parenting stress. The relation between mothers’ parenting stress and mother–child closeness was stronger than the relation between grandmothers’ parenting stress and grandmother–child closeness. Findings highlight the implications of using a family system perspective and the dyadic approach in understanding and improving family functioning in Chinese three-generation households. 相似文献

The factor structure of the Heterosexist Harassment, Rejection, and Discrimination Scale (HHRDS) was examined in lesbian, gay, bisexual, transgender, and queer (LGBTQ) people of colour. Two hundred participants completed a survey with the HHRDS and several mental health scales. A confirmatory factor analysis suggested the original HHRDS structure fit the data poorly. Exploratory factor analyses found a different 2-factor structure, consisting of harassment/rejection and family discrimination. Convergent validity analyses demonstrated that family discrimination had the largest association with depression and anxiety, indicating that family discrimination may be particularly salient among LGBTQ people of colour. This study supports the use of the HHRDS in racially/ethnically diverse samples, but with a slightly different factor structure. Examining discriminatory experiences from family members is an important direction for future research in LGBTQ people of colour. 相似文献

Previous work from our laboratory showed that intermittently re-exposing rats to reinforcement for lever pressing in a training (A) context, while eliminating lever pressing in a second (B) context, increased ABA renewal of lever pressing relative to rats that experienced only Context B during response elimination. In the current study, we replicated these procedures while assessing renewal in the presence of a novel context (i.e., ABC renewal). Unlike the findings described above, renewal was reduced in the group that experienced re-exposure to Context A during lever-press elimination relative to rats that experienced only Context B. These findings suggest that alternating between contexts associated with reinforcement and extinction during treatment reduces the probability that organisms will respond in novel contexts. These outcomes may be the result of discrimination and/or generalization processes. Moreover, this training procedure may offer a potential mitigation strategy for ABC renewal. 相似文献

There is high variability in efficacy for interventions for youth with disruptive behavior problems (DBP). Despite evidence of the unique correlates and critical consequences of girls’ DBP, there is a dearth of research examining treatment efficacy for girls. This meta-analysis of 167 unique effect sizes from 29 studies (28,483 youth, 50% female; median age: 14) suggests that existing treatments have a medium positive effect on DBP (g = .33). For both boys and girls, the most effective interventions included (a) multimodal or group format, (b) cognitive skills or family systems interventions, and (c) length-intensive programs for (d) younger children. Boys demonstrated significantly greater treatment gains from group format interventions compared to girls, which is particularly important given that the group program format was the most prevalent format for boys and girls, with 14 studies involving 10,433 youth encompassing this category. This is the first meta-analysis to examine the effect of program characteristics in a sample of programs selected to be specifically inclusive of girls. Given that girls are underrepresented in intervention research on DBP, findings are discussed in terms of gender-responsive considerations and elucidating how key aspects of program structure can support more effective intervention outcomes for youth. 相似文献

Young Black gay/bisexual men (YBGBM) are a highly marginalized population across multiple health outcomes. Most research on YBGBM health has focused on HIV/sexual health, but there is a demonstrable need for research examining racism and psychosocial functioning among this population. Racialized Sexual Discrimination (RSD), also known as sexual racism, is an important but under-investigated phenomenon that may have implications for the psychological health and well-being of YBGBM. This paper provides an overview of empirical research on RSD as experienced by gay/bisexual men of color in online partner-seeking venues. First, the researchers discuss how racialized experiences are a documented online phenomenon, with a variety of manifestations, and identify the potential effects that this phenomenon may have on the psychosocial health of YBGBM, and gay/bisexual men of color as a whole. Second, the researchers synthesize the RSD literature with a broader literature examining psychological well-being across race and sexual orientation. Third, the researchers present a theoretically grounded conceptual model detailing the pathways between RSD and psychological well-being using a stress and coping framework. The paper concludes with recommendations for future research on this topic, including scale development and hypothesis testing. 相似文献

The intersectionality of race/ethnicity and socioeconomic status (SES) in predicting social and emotional (SE) skills was examined for 81,950 6th–8th graders. At low levels of SES, White students tended to have the lower SE scores. However, as SES increased, they tended to have higher scores relative to minority groups. Across SES levels, Asian students showed higher Academic Discipline and Self-Regulation scores. The SES and SE skill relationship was less pronounced for underserved minority groups. This may be among the first reports where a measure of SE skills has documented different relationships with SES as a function of race/ethnicity. Possible explanations for these findings, as well as implications for designing culturally responsive programs that focus on SE skills, are discussed. 相似文献
