Non-suicidal self-injury (NSSI) in childhood is not well documented, especially among youth with pediatric bipolar disorder (PBD). The current study evaluated prevalence and correlates of NSSI, and its impact on intervention response, in a randomized trial of Child- and Family-Focused Cognitive-Behavioral Therapy (CFF-CBT) versus Treatment As Usual (TAU), adjunctive to pharmacotherapy. This study included 72 children ages 7–13 (58% male) with PBD. NSSI and correlates were assessed at baseline; mood and psychiatric severity were measured longitudinally. NSSI was common: 31% endorsed NSSI behaviors; 10% reported thoughts of NSSI, in the absence of behaviors. Children engaging in NSSI reported higher depression, psychosis, suicidality, and hopelessness; lower self-esteem; and reduced family help-seeking in univariate analyses. In a multivariate logistic regression, high child depression and psychosis, and low family help-seeking, remained significantly associated with baseline NSSI. In mixed-effects regression models, presence of NSSI at baseline did not influence the response of depressive symptoms to treatment. Children who endorsed NSSI experienced steeper response trajectories for psychiatric severity, regardless of treatment group. Youth who denied NSSI showed poorer response to TAU for manic symptoms; mania trajectories in CFF-CBT were similar across youth. Thus, NSSI in PBD is common and associated with impairment. As children might engage in NSSI for different reasons, the function of NSSI should be considered in treatment. Since children without NSSI fared worse in TAU, it may be important to ensure that youth with PBD receive structured, intensive interventions. CFF-CBT was efficacious regardless of NSSI, and thus shows promise for high-risk children with PBD. 相似文献

When Extremists Win: Cultural Transmission Via Iterated Learning When Populations Are Heterogeneous 下载免费PDF全文
Danielle J. Navarro Amy Perfors Arthur Kary Scott D. Brown Chris Donkin 《Cognitive Science》2018,42(7):2108-2149
How does the process of information transmission affect the cultural or linguistic products that emerge? This question is often studied experimentally and computationally via iterated learning, a procedure in which participants learn from previous participants in a chain. Iterated learning is a powerful tool because, when all participants share the same priors, the stationary distributions of the iterated learning chains reveal those priors. In many situations, however, it is unreasonable to assume that all participants share the same prior beliefs. We present four simulation studies and one experiment demonstrating that when the population of learners is heterogeneous, the behavior of an iterated learning chain can be unpredictable and is often systematically distorted by the learners with the most extreme biases. This results in group‐level outcomes that reflect neither the behavior of any individuals within the population nor the overall population average. We discuss implications for the use of iterated learning as a methodological tool as well as for the processes that might have shaped cultural and linguistic evolution in the real world. 相似文献

The goals of the current study were to describe parents’ emotion socialization patterns and to assess relations between parents’ emotion-related beliefs and socialization behaviors during conversations with their children. Participants were 125 parents and their 9- and 10-year-old children from three ethnic groups in the southeastern United States. Parents reported beliefs about children’s emotions. Parents and children were videotaped playing a board game to evoke emotion-related conversations, which were then coded for parents’ labeling, teaching, and encouragement of emotion. Parents used less labeling and teaching for positive than negative emotions, and greater encouragement for positive than negative emotions. Parents with stronger beliefs about the value of positive emotions engaged in less labeling of positive emotions, less teaching of all emotions, and less encouragement of negative emotions. Parents with stronger beliefs about the value of negative emotions engaged in more encouragement of negative emotions. Parents with stronger beliefs that all emotions are dangerous engaged in less labeling of negative emotions. The results of this study have potential clinical implications in helping clients to understand the foundational structures of their behaviors and how both beliefs and behaviors are distinct, yet interrelated constructs. 相似文献

This study extends the over-scheduling hypothesis literature by focusing on affluent adolescents and exploring relations between psychosocial adjustment and reasons for organized activity (OA) involvement rather than focusing solely on time spent in OAs. Variable- and person-centered analyses were used to evaluate associations between intensity of OA participation and reasons for involvement, perceived parental pressure, and adjustment (depressive symptoms, anxiety symptoms, life satisfaction) in a sample of 10th graders (N = 122) from affluent communities. When adolescents’ perceptions of parental pressure were controlled for in analyses, more intensely involved youth reported lower levels of depressive symptoms. “For Fun” was the most highly rated reason for involvement and was linked to lower levels of perceived parental pressure, but was unrelated to all indicators of adjustment. Conversely, involvement in OAs “for Parents” was linked to more perceived parental pressure and lower levels of life satisfaction. Two OA participant profiles emerged in person-centered analyses: (1) primarily intrinsic reasons (high Fun, moderate Future, low Parents) and (2) intrinsic and extrinsic reasons (high Fun, high Future, high Parents) for involvement. OA participation simultaneously motivated by extrinsic and intrinsic reasons was linked to fewer psychosocial benefits than intrinsically motivated OA involvement. 相似文献

Background: High rates of stress-related problems in college students and low utilization of treatment options demonstrate the need for effective stress-reducing interventions that can be self-regulated. This study compared the effect of brief paced-breathing with biofeedback and exercise interventions on heart rate variability, state anxiety and affect. Methods: Students (n?=?32) with high levels of perceived stress completed three 10-min interventions on separate days: paced-breathing with biofeedback (Biofeedback), a self-paced walk (Exercise), and an attention control condition of quiet studying (Quiet Study). Anxiety and affect were measured before (Pre), immediately after (Post0) and 15 mins after (Post15) the intervention. Heart rate variability was measured pre- and post-intervention using electrocardiogram. Results: Biofeedback reduced anxiety more than the exercise condition (Pre to Post0: Biofeedback d?=??0.48, Exercise d?=??0.13). Secondly, Exercise temporarily increased energy (Pre to Post0: d?=?0.67), whereas Biofeedback temporarily increased calmness (Pre to Post0: d?=?0.51). All conditions significantly increased total heart rate variability (p?.05). Conclusions: Biofeedback and Exercise interventions improved emotional states in high-stress college students, but the type of change observed (i.e. energizing, calming or anxiety reducing) depended upon the condition. 相似文献

Behavioral Variability in the Play of Children With Autism and Their Typically Developing Peers 下载免费PDF全文

Invariable or repetitive behavior is a defining feature of autism and can limit a child's exposure to varying consequences and subsequent learning opportunities. We compared the variability in play material selection between 30 children with autism and 30 typically developing children, aged 2‐8 years, across three different activities: selecting paper outfits to dress dolls, selecting beads to place on a string, and choosing marker colors for coloring shapes. Selections of materials could be varied or identical to previous selections within the session. Although there was some overlap between the two groups, children with autism were more likely to respond invariably than typically developing children. Two‐year‐old children in both groups tended to display invariable play material selection, but variability increased across increasing age groups for typical children and remained relatively stable across increasing age groups for children with autism. Implications regarding the divergence in variable behavior across children with autism and typically developing children as a function of age are discussed.

The changing milieu of research—increasingly global, interdisciplinary and collaborative—prompts greater emphasis on cultural context and upon partnership with international scholars and diverse community groups. Ethics training, however, tends to ignore the cross-cultural challenges of making ethical choices. This paper confronts those challenges by presenting a new curricular model developed by an international team. It examines ethics across a very broad range of situations, using case studies and employing the perspectives of social science, humanities and the sciences. The course has been developed and taught in a highly collaborative way, involving researchers and students at Zhejiang University, the Indian Institute of Technology, Bombay and Brown University. The article presents the curricular modules of the course, learning outcomes, an assessment framework developed for the project, and a discussion of evaluation findings. 相似文献

Many theorists posit that religiousness/spirituality (RS) may change after trauma. However, empirical findings regarding RS following trauma are inconclusive. The present study examined the relationship between potentially traumatic events (PTEs) and current RS by considering the cumulative effect of PTEs and multiple dimensions of RS. In our sample of 245 undergraduates (60% female, 79% White), there were no differences in RS between participants who did and did not have PTEs. When analysed as a continuous variable, the number of PTEs was positively correlated with many RS dimensions (i.e., daily spiritual experiences, religious strain, religious comfort, provident and challenging God images, belief in God) but not all (i.e., organised religious involvement, belief in afterlife, benevolent God image). These results suggest that PTEs relate distinctly to different aspects of RS and that examining multiple dimensions of RS may be a more informative way of studying this association. 相似文献
