Children of depressed mothers show substantial social impairment, which increases their risk for developing depression. Theory of mind understanding forms the basis of social functioning, and is impaired in children of currently depressed mothers. Models of risk emphasize that a history of any maternal depression confers risk to later psychopathology. Therefore, we tested a novel model of the impact of lifetime maternal depression on children’s false belief understanding that accounts for three primary factors that scaffold this understanding: maternal mental state talk, and children’s executive functioning and language abilities. Children aged 41–48 months with a maternal lifetime history of major depressive disorder (MDD; n = 19) performed significantly more poorly on the false belief battery compared to those without (n = 44). Further, lower levels of mental state talk, child executive functioning, and child language ability were significantly associated with poorer false belief scores. However, the relation between maternal MDD and children’s false belief performance was not mediated by any of these factors. These results indicate that maternal depression predicts poorer false belief understanding independently of other crucial scaffolding variables, and may be a social cognitive mechanism underlying the intergenerational transmission of depression.  相似文献

This article summarizes the four articles in the Social Development quartet focused on positive affect regulation in youth. Each article in the quartet shows that parents’ socialization of youth positive affect (e.g., encouraging, enhancing, savoring, or dampening responses) is associated with youth positive affect regulation and depressive symptoms. Further, three of the studies provide novel evidence for an indirect relationship whereby parental socialization predicts youth depressive symptoms through youth positive affect regulation. The studies include samples of youth across mid‐childhood and adolescence (7–18‐year‐olds) from three countries (the United States, Belgium, and India), and utilize several methods of assessing youth positive affect regulation or parental socialization (parent‐reported surveys, youth‐reported surveys, coded parent–child discussions). This integrative article also identifies several ways in which the study of youth positive affect regulation can be advanced. We address the conceptualization of positive affect regulation and the socialization of children's positive affect, constraints on the adaptiveness of upregulating positive emotions, methodological directions, potential moderated effects based on child characteristics such as sex or temperament, and the importance of studying outcomes beyond depression.  相似文献

This paper presents an analysis of components of successful social work evaluation research practice. Among the key obstacles to successful evaluations of social work intervention are the impoverished knowledge base on which many social work interventions are based, the isolation of researchers and practitioners in the conduct of evaluations, and during research implementation failure to cope with the changing field context. To remedy this situation social work needs to invest in university and social agency partnerships focussed on knowledge building for the profession. In such partnerships the traditional roles of the researcher and the practitioner are altered so that shared responsibility for knowledge development is possible. In addition, to deal with changing field contexts the research team needs to be continuously engaged in problem solving and redesign. An initial example of such a partnership is described together with a case study illustrating implementation of a multi-site field experiment evaluation.  相似文献

Direct scribing is a technique that transforms oral discourse into written text, basically by typing oral material verbatim . It was developed in practice with youth in child welfare care and adapted for research data collection. The technique flattens the power imbalance in the interview situation and between oral speech and written text, supports self-reflection, democratizes the ownership of written material, is potentially empowering, and is an efficient means to produce high-quality text. The origins in practice are reviewed and a research application is discussed in detail. Thirty youths aged 18/19 from child welfare constructed self-narratives about how they conceptualized and managed the adolescent transition, and collaborated with the researcher in analysing the narrative as a story. Each interview was direct scribed and printed copy given to the participant. Participants were introduced to direct scribing by completing a questionnaire presented on a note-book computer, and some took part in a gender-specific group discussion as a final data-collection event, which was audio-taped and transcribed. The value of direct scribing and self-narrative in this research project and possibilities for other applications are discussed.  相似文献

This study aimed to support the theory of popularity contagion, which posits that popularity spreads among friends spontaneously and regardless of behavioral changes. Peer nominations of status and behavior were collected annually between 6th and 12th grades from a total of 1062 adolescents. Longitudinal hypotheses were mostly supported using path analyses, showing (1) that individual popularity could be predicted by friends’ popularity levels over time, even when controlling for stability of individual popularity; (2) that this prediction was not accounted for by behavioral contagion of aggressive or prosocial behaviors; and (3) that individual social preference generally could not be predicted by friends’ preference levels over time. Implications, limitations, and directions for future research are discussed.  相似文献

This discussion paper suggests that there is possibly a divergence of opinion taking place within the field of child and family social work and that the stated positions are influencing how practitioners identify and deal with risks and opportunities afforded by the Internet and social media. The suggested divergence is examined and the conclusion drawn is that what is taking place mirrors the fact that the introduction of any new technology inevitably brings with it division and debate. In seeking to understand the reaction to digital technology, consideration is given to a series of wider social discourses on childhood and risk, which includes the controversial notion that the profession is a harbinger of moral panic and that the management of risk has been broadened from child protection to child safety. The discussion paper concludes by calling for child and family social work practitioners to have a balanced debate that needs to be informed not only by current research but also by an open and honest discussion about personal use and an acknowledgement that there will be difficult moral and ethical questions to work through.  相似文献

This study investigated developmental trajectories for prosocial behavior for a sample followed from the age of 10–18 and examined possible adjustment outcomes associated with membership in different trajectory groups. Participants were 136 boys and 148 girls, their teachers, and their parents (19.4 percent African‐American, 2.4 percent Asian, 51.9 percent Caucasian, 19.5 percent Hispanic, and 5.8 percent other). Teachers rated children's prosocial behavior yearly in grades 4–12. At the end of the 12th grade year, teachers, parents, and participants reported externalizing behaviors and participants reported internalizing symptoms, narcissism, and features of borderline personality disorder. Results suggested that prosocial behavior remained stable from middle childhood through late adolescence. Group‐based mixture modeling revealed three prosocial trajectory groups: low (18.7 percent), medium (52.8 percent), and high (29.6 percent). Membership in the high prosocial trajectory group predicted lower levels of externalizing behavior as compared with the low prosocial trajectory group, and for girls, lower levels of internalizing symptoms. Membership in the medium prosocial trajectory group also predicted being lower on externalizing behaviors. Membership in the high prosocial trajectory group predicted lower levels of borderline personality features for girls only.  相似文献
