Disruptive behavior disorders are prevalent in youth, yet most children with disruptive behavior do not have access to timely, effective treatment. Distance-delivered service (e.g., via telephone, Internet) can overcome several barriers to care. This study tested the effectiveness of a 12-week parent training program, Strongest Families? Parenting the Active Child, delivered via written material, skill-based videos, and telephone coaching sessions, as compared to usual care in reducing child externalizing behavior. Participants were 172 primary caregivers of a 6- to 12-year-old (29% girls; M age?=?8.5 years) recruited from community children’s mental health clinics. Participants were randomized to either Strongest Families? or usual care and completed measures of child externalizing behavior, parenting practices, parent distress, and intervention services consumed at baseline and 5-, 10-, 16-, and 22-months post-baseline. Growth curve analysis showed significant reductions in externalizing behavior in both conditions over time. Improvements were significantly greater at 10 months in the Strongest Families? condition (d =?0.43). At 22 months, however, the differences were not significant and small in magnitude (d =??0.05). The intervention decreased inconsistent discipline significantly more than usual care. Parents in both conditions showed significant reductions in distress. We also conducted a cost-effectiveness analysis to assess the value for money of the Strongest Families? program versus usual care. Distance parent training is a promising way to increase access to, and reduce costs associated with, mental health care for families with a child with disruptive behavior. 相似文献

Human and non‐human primates share the ability to extract adjacent dependencies and, under certain conditions, non‐adjacent dependencies (i.e., predictive relationships between elements that are separated by one or several intervening elements in a sequence). In this study, we explore the online extraction dynamics of non‐adjacent dependencies in humans and baboons using a serial reaction time task. Participants had to produce three‐target sequences containing deterministic relationships between the first and last target locations. In Experiment 1, participants from the two species could extract these non‐adjacent dependencies, but humans required less exposure than baboons. In Experiment 2, the data show for the first time in a non‐human primate species the successful generalization of sequential non‐adjacent dependencies over novel intervening items. These findings provide new evidence to further constrain current theories about the nature and the evolutionary origins of the learning mechanisms allowing the extraction of non‐adjacent dependencies. 相似文献

The literature provides solid documentation of the negative consequences of poor psychosocial functioning and behavioral problems in early childhood. Children facing economic disadvantage are at higher risk for poor socio-emotional development and problem behaviors, which draws attention to the need for prevention targeted at this risk group. The aim of our study was to analyze the impact of an evidence-based teacher-training program, the Incredible Years Teacher Classroom Management (IY-TCM), on the behavior of economically disadvantaged Portuguese children. Participants were 1030 children aged 3–6 years, from 65 preschool classrooms selected for their high percentage of children from economically disadvantaged backgrounds. The study followed an experimental randomized controlled between-group design, with pre- and post-intervention assessments. Teachers in the experimental group attended the IY-TCM program, implemented in six monthly workshops, and four sessions of individual in-class support. Children outcomes were evaluated with the Preschool and Kindergarten Behavior Scales—2nd Edition (Social Skills and Problem Behavior scales). After the intervention, preschoolers in the IY-TCM classrooms showed more improvements in their social skills and more decreases in problem behavior. Children with lower levels of social skills (high risk) at pre-intervention and those coming from families in economic need showed greater improvements in social skills, but these effects were not observed for problem behavior. Results support the growing evidence of the effectiveness of the IY-TCM as a stand-alone, non-adapted program in a Portuguese cultural context, which can play a protective role in children’s lives and thus bridge the gap between children coming from different economic backgrounds. 相似文献

Variant interpretation is a complex process, and classification may vary between sources. This study aimed to determine the practice of cancer genetic counselors regarding discrepancies in variant interpretation and to identify concerns when counseling these discrepancies. An electronic survey was sent to genetic counselors in the NSGC Cancer Special Interest Group. The vast majority of counselors (93%) had seen a variant interpretation discrepancy in practice. A large majority (96%) of respondents indicated that they conducted their own research on reported variants. Most respondents cited variant databases as the most common resource utilized in researching variants. Approximately 33% of counselors spent 45 min or more of extra time researching a discrepancy compared to researching a variant with a single classification. When asked how they approached counseling sessions involving variant interpretation discrepancies, the free responses emphasized that counselors considered family history, clinical information, and psychosocial concerns, showing that genetic counselors tailored the session to each individual. Discrepancies in variant interpretation are an ongoing concern for clinical cancer genetic counselors, as demonstrated by the fact that counselors desired further resources to aid in addressing these discrepancies, including a centralized database (89%), guidelines from a major organization (88%), continuing education about the issue (74%), and functional studies (58%). Additionally, most respondents reported that the ideal database would be owned by a non-profit organization (59%) and obtain information directly from laboratories (91%). This investigation was the first to address these discrepancies from a clinical point of view. The study demonstrates that discrepancies in variant interpretation are a concern for clinical cancer genetic counselors and outlines the need for additional support. 相似文献

Fibromyalgia (FM) is a chronic pain syndrome that includes debilitating symptoms such as widespread pain and tenderness, fatigue, and poor physical functioning. Research has shown FM patients’ choice of coping style and relationship quality with their spouse can impact their mental quality of life (QoL), but no known study has examined the protective nature of relationship quality and coping behaviors on both patient physical and mental QoL in the context of chronic pain. We examined 204 patients with FM on the (a) roles of coping styles and relationship quality on patient quality of life, and (b) moderating effect of relationship quality on the association between negative coping style and patient QoL. A series of multiple regressions found patients’ coping styles were not significantly associated with physical QoL, but were significantly associated with mental QoL. Patients’ relationship quality with their spouse was significantly associated with mental QoL, but not physical QoL and no significant interactions with negative coping style were found. Our results emphasize the importance of coping styles and relationship quality between patients and their spouses in the context of chronic pain. Clinicians can incorporate the patient’s relationship as part of a more holistic approach to care and improving outcomes. 相似文献

Numerous studies have established that the social context greatly affects adolescent risk taking. However, it remains unexplored whether adolescents' decision‐making behaviors change when they take risks that affect other individuals such as a parent. In the current study, we sought to investigate how the social context influences risky decisions when adolescents' behavior affects their family using a formalized risk‐taking model. Sixty‐three early adolescents (Mage = 13.3 years; 51% female) played a risk‐taking task twice, once during which they could make risky choices that only affected themselves and another during which their risky choices only affected their parent. Results showed that adolescents reporting high family conflict made more risky decisions when taking risks for their parent compared to themselves, whereas adolescents reporting low family conflict made fewer risky decisions when taking risks for their parent compared to themselves. These findings are the first to show that adolescents change their decision‐making behaviors when their risks affect their family and have important implications for current theories of adolescent risk taking. 相似文献

Physical processes manifest an objective order that science manages to discover. Commonly, it is considered that these processes obey the “laws of nature.” Bergson disputes this idea which ultimately constitutes a kind of Platonism. In contrast, he develops the idea that physical processes are a particular case of automatic behaviors. In this sense, they imply a motor memory immanent to matter, whose actions are triggered by some perceptions. This approach is obviously panpsychist. It gives matter a certain consciousness, even if the latter is different in nature from our consciousness. In some respects, this approach is similar to contemporary panpsychism because it claims that the psychic is a fundamental characteristic of nature, causally active. But it is also original because it does not constitute a theory of the origin of mind in nature. 相似文献

A network analysis approach to psychopathology regards symptoms as mutually interacting components of a multifaceted system (Borsboom & Cramer, 2013). Although several studies using this approach have examined comorbidity between disorders using cross-sectional samples, a direct application of the network analysis approach to intraindividual dynamic relations between symptoms in a complex, comorbid case has not been reported. The current article describes an intraindividual dynamic network analysis (IDNA) approach to understanding the psychopathology of an individual using dynamic (over time) lead-lag interrelations between symptoms. Multivariate time series data were utilized to create and examine an intraindividual, lag-1 network of the partial, day-to-day relations of symptoms in an individual with comorbid mood and anxiety disorders. Characteristics of the network, including centrality indices, stability, dynamic processes between symptoms, and their implications for clinical assessment are described. Additional clinical implications and future directions for IDNA, including the potential incremental validity of this assessment approach for empirically-based idiographic assessment and personalized treatment planning, are discussed. This person-specific IDNA approach may be especially useful in complex and comorbid cases. 相似文献

Many learners have difficulties with rational number tasks because they persistently rely on their natural number knowledge, which is not always applicable. Studies show that such a natural number bias can mislead not only children but also educated adults. It is still unclear whether and under what conditions mathematical expertise enables people to be completely unaffected by such a bias on tasks in which people with less expertise are clearly biased. We compared the performance of eighth‐grade students and expert mathematicians on the same set of algebraic expression problems that addressed the effect of arithmetic operations (multiplication and division). Using accuracy and response time measures, we found clear evidence for a natural number bias in students but no traces of a bias in experts. The data suggested that whereas students based their answers on their intuitions about natural numbers, expert mathematicians relied on their skilled intuitions about algebraic expressions. We conclude that it is possible for experts to be unaffected by the natural number bias on rational number tasks when they use strategies that do not involve natural numbers. 相似文献
