Atypical reward processing, including abnormal reward responsivity and sensitivity to punishment, has long been implicated in the etiology of ADHD. However, little is known about how these facets of behavior interact with positive (e.g., warmth, praise) and negative (e.g., hostility, harsh discipline) parenting behavior in the early expression of ADHD symptoms in young children. Understanding the interplay between children’s reward processing and parenting may be crucial for identifying specific treatment targets in psychosocial interventions for ADHD, especially given that not all children benefit from contingency-based treatments (e.g., parent management training). The study consisted of a sample of kindergarten children (N?=?201, 55% male) and their parents, who completed questionnaires about their parenting practices, their child’s behaviors and participated in an observed parent-child play task in the laboratory. Children’s reward responsivity and sensitivity to punishment were positively associated with child ADHD symptoms. However, children with high reward responsivity had more symptoms of ADHD but only under conditions of low negative parenting (self-reported and observed) and high self-reported positive parenting, compared to children with low reward responsivity. Children with high sensitivity to punishment had more ADHD symptoms relative to children with low sensitivity to punishment, but only under conditions in which observed praise was infrequent. Results provide evidence that individual differences in sensitivity to reward/punishment may be an important of marker of risk for ADHD, but also highlights how children’s responses to positive and negative parenting behavior may vary by children’s sensitivities. Clinical and treatment implications are discussed.  相似文献

Since the September 11th attacks on the U.S., more than 2 million children have experienced parental deployment during their early years, with potentially lasting impact. When a parent is deployed, a number of factors may affect the well-being of the service member and his/her family. One parental factor—posttraumatic stress disorder or distress—might be particularly powerful in its effect on young children and the family system. We analyzed baseline data from an intervention development project which focused on supporting military families with very young children during post-deployment. The purpose of this research is to understand the relationships between parental mental health status, parenting stress, couple functioning, and young child well-being. The effects of mental health status of home-front and service member parents and the role of couple functioning on parent–child interactions and behavioral problems of young children were examined in a sample of military families during the post-deployment period. Findings suggest that service member posttraumatic stress symptoms are associated with higher parental report of child behavior problems. Higher quality of the couple relationship appears to lessen the impact of parental posttraumatic stress but is not related to parent perceptions of child behavior concerns. Implications for future research with military families are discussed.  相似文献

The current study aimed to develop and evaluate a measure of parenting knowledge, the Knowledge of Parenting Strategies Scale (KOPSS); specifically, to establish the scales internal reliability, ensure a clinically appropriate length, provide a community sample for future comparison, demonstrate adequate test–retest reliability and convergent validity, and to compare the scale to dysfunctional discipline styles. A total of n?=?865 parents were involved in the development and evaluation of the scale. In Study 1, data was collected from n?=?229 parents and Rasch analyses revealed seven items did not fit the measurement model. Study 2 involved a further sample of community families (n?=?346) and revealed the scale could be further shortened to 16 items. Study 3 revealed the scale has good test–retest reliability over a one-week period (r?=?.88, p?<?.001). Study 4 demonstrated convergent validity through a comparison to the Knowledge of Effective Parenting Scale (r?=?.583, p?=?.009). Study 5 utilised a sample of community families (n?=?190), revealing the scale was negatively correlated with hostile and lax discipline (r?=??.29, p?<?.001; r?=??.15, p?<?.05). Lastly, Study 6 showed scores on the KOPSS significantly improved following clinic-based and Internet-based Behavioural Parent Training. The KOPSS was found to be a valid and reliable measure of parenting knowledge of effective parenting strategies, which can be used to evaluate knowledge acquisition in parenting programs, and test the role of knowledge in behaviour change.  相似文献

Recent research has found that a strong family allocentrism relates to reduced adolescent depressive symptoms. Besides providing continuous support for this relation, this research extended the scope by exploring whether there was a U-shaped association between family allocentrism and depressive symptoms and testing the mediation effect of identity style among Italian adolescents (N?=?387, 183 boys, 204 girls, Mage?=?16.38 years). Result of hierarchical regression model showed that the association between family allocentrism and depressive symptoms was linear rather than U-shaped. More importantly, this linear relation was mediated by normative and diffuse-avoidant style. In sum, the current findings suggest that adolescents who are allocentric toward family tend to follow family members’ expectations to establish self-identity and deal with identity issues more proactively, and thus they are less likely to experience depressive symptoms. Moreover, there is no significant evidence that too much family allocentrism would lead to elevated depressive symptoms.  相似文献

Bi-ethnic adolescents of marriage migrant mothers in Korea are often encouraged to be “pure” Koreans for their adjustments and not given the opportunities to explore their ethnic identity or to learn about their mother’s culture of origin. Existing studies conducted with mono-ethnic minorities in other countries, however, do not support this belief. We tested a conceptual model on the role of ethnic socialization, ethnic identity and self-esteem on school adjustment among bi-ethnic adolescents in Korea based on social identity theory and theoretical models of ethnic socialization and ethnic identity. We used data from 2015 National Survey of Multicultural Families. The study sample consisted of 296 adolescents aged 9–18 who were born between Korean fathers and Vietnamese marriage migrant mothers. We used structural equation modeling to specifically examine the association between ethnic socialization in terms of parents’ linguistic socialization and adolescents’ school adjustment mediated by ethnic identity in the form of ethnic regard and self-esteem among bi-ethnic adolescents. The results verified the hypothesized model, showing positive relationships between linguistic socialization and ethnic regard, ethnic regard and self-esteem, self-esteem and school adjustment, and ethnic regard and school adjustment. Additionally, the results of bootstrapping test showed that the indirect effect of linguistic socialization on self-esteem through ethnic regard was significant. The indirect effect of ethnic regard on school adjustment through self-esteem was significant and the indirect effect of linguistic socialization on school adjustment via ethnic regard and self-esteem was also significant. These results shed light on the important role of ethnic identity fostered at home among bi-ethnic adolescents of marriage migrant mothers in Korea.  相似文献

The social-cognitive processing model suggests that a socially constrained environment may impede adjustment to a chronic illness. The present study primarily investigated the mediating psychological pathways through which social constraints on cancer-related disclosure, low optimism, disengagement-oriented coping, and brooding could be associated with low levels of psychosocial adjustment. One hundred twenty-five female breast cancer survivors participated in a cross-sectional study. Path analysis was used to examine the proposed model. Low optimism, increased social constraints, and higher levels of brooding appeared to be risk factors for poor psychosocial adjustment to breast cancer. Disengagement-oriented coping and brooding partially mediated the relationship between social constraints and adjustment. Brooding totally mediated the relationship between disengagement-oriented coping and adjustment. The current findings provide support for the value of the social-cognitive processing model among breast cancer survivors. The mapping of psychological pathways of adjustment to breast cancer may have useful clinical implications for better adjustment outcomes.  相似文献

It has been argued that some animals are moral subjects, that is, beings who are capable of behaving on the basis of moral motivations (Rowlands 2011, 2012, 2017). In this paper, we do not challenge this claim. Instead, we presuppose its plausibility in order to explore what ethical consequences follow from it. Using the capabilities approach (Nussbaum 2004, 2007), we argue that beings who are moral subjects are entitled to enjoy positive opportunities for the flourishing of their moral capabilities, and that the thwarting of these capabilities entails a harm that cannot be fully explained in terms of hedonistic welfare. We explore the implications of this idea for the assessment of current practices involving animals.  相似文献

As genomic sequencing becomes more widely available in clinical settings for diagnostic purposes, a number of genetic counseling issues are gaining precedence. The ability to manage these issues will be paramount as genetic and non-genetic healthcare professionals navigate the complexities of using genomic technologies to facilitate diagnosis and inform patient management. Counseling issues arising when counseling for diagnostic genomic sequencing were identified by four genetic counselors with 10 years of collective experience providing genetic counseling in this setting. These issues were discussed and refined at a meeting of genetic counselors working in clinical genomics settings in Melbourne, Australia. Emerging counseling issues, or variations of established counseling issues, were identified from the issues raised. Illustrative cases were selected where pre- and post-test genetic counseling was provided in clinical settings to individuals who received singleton or trio WES with targeted analysis. Counseling issues discussed in this paper include a reappraisal of how genetic counselors manage hope in the genomic era, informed consent for secondary use of genomic data, clinical reanalysis of genomic data, unexpected or unsolicited secondary findings, and trio sequencing. The authors seek to contribute to the evolving understanding of genetic counseling for diagnostic genomic sequencing through considering the applicability of existing genetic counseling competencies to managing emerging counseling issues and discussing genetic counseling practice implications.  相似文献

This paper explores patients’ views and experiences of undergoing treatment-focused BRCA1 and BRCA2 genetic testing (TFGT), either offered following triaging to clinical genetics (breast cancer) or as part of a mainstreamed care pathway in oncology (ovarian cancer). Drawing on 26 in-depth interviews with patients with breast or ovarian cancer who had undergone TFGT, this retrospective study examines patients’ views of genetic testing at this point in their care pathway, focusing on issues, such as initial response to the offer of testing, motivations for undergoing testing, and views on care pathways. Patients were amenable to the incorporation of TFGT at an early stage in their cancer care irrespective of (any) prior anticipation of having a genetic test or family history. While patients were glad to have been offered TFGT as part of their care, some questioned the logic of the test’s timing in relation to their cancer treatment. Crucially, patients appeared unable to disentangle the treatment role of TFGT from its preventative function for self and other family members, suggesting that some may undergo TFGT to obtain information for others rather than for self.  相似文献
