Internationally adopted (IA) children have often experienced early adversity and are at risk for long‐term deficiencies in multiple developmental domains. This study examined the association between IA children's joint attention (JA) soon after arrival and later cognitive, communicative, and socioemotional competency 6 months’ postadoption. We expected a child's initial JA would positively predict later cognitive, communication, and social ability. IA children (n = 63) adopted from Eastern Europe were seen soon after their arrival into the United States to assess their JA. Their socioemotional competency, social communication, and cognitive abilities were measured at a follow‐up session 6 months’ postadoption. We found that higher order JA was positively associated with measures of social relatedness. Furthermore, individual hierarchical regressions of each measure of JA (higher order JA, initiating JA, responding to JA, and initiating behavior requests [BR]) considered with age‐at‐adoption showed that each measure was an independent and positive predictor of Mullen outcomes in the receptive and expressive language domains. These results suggest that JA may be a sensitive predictor of subsequent functioning in the social, communicative, and cognitive domains. Thus, assessing JA soon after arrival has the potential to identify at‐risk IA children, and interventions targeting JA may support those children in overcoming the negative impacts of early adversity.  相似文献

Three subdimensions of ODD symptoms have been proposed –angry/irritable (IR), argumentative/defiant (DF) and antagonism (AN). This study tested whether longitudinal symptom trajectories could be identified by these subdimensions. Group-based trajectory analysis was used to identify developmental trajectories of IR, DF and AN symptoms. Multi-group trajectory analysis was then used to identify how subdimension trajectories were linked together over time. Data were drawn from the Pittsburgh Girls Study (PGS; N = 2450), an urban community sample of girls between the ages of five--eight at baseline. We included five waves of annual data across ages five-13 to model trajectories. Three trajectories were identified for each ODD subdimension: DF and AN were characterized by high, medium and low severity groups; IR was characterized by low, medium stable, and high increasing groups. Multi-trajectory analysis confirmed these subdimensions were best linked together based on symptom severity. We did not identify girls’ trajectory groups that were characterized predominantly by a particular subdimension of ODD symptoms. Membership in more severe symptom groups was significantly associated with worse outcomes five years later. In childhood and early adolescence girls with high levels of ODD symptoms can be identified, and these youth are characterized by a persistently elevated profile of IR, DF and AN symptoms. Further studies in clinical samples are required to examine the ICD-10 proposal that ODD with irritability is a distinct or more severe form of ODD.  相似文献

The separate and combined efficacy of a social norms and a self-affirmation intervention to motivate decreased sugar-sweetened beverage (SSB) consumption was examined in 2 experiments. College students were randomly assigned to receive information about SSB consumption risks, norms, both, or neither. In addition, participants performed either a self-affirmation or control task. Self-affirmation only weakly affected SSB consumption intentions and behaviors. However, participants in Experiment 2 who received risks information, norms information, or both reported greater SSB reduction intentions than did those who received no information. Two weeks later, those who received both types of information reported more frequent behavior change preparations, and it appears this effect may have been partially mediated by the changes in intentions to reduce SSB consumption.  相似文献

Although managers and researchers put utmost importance on uncovering factors that affect effort and performance of sales representatives, they have largely overlooked a key factor. This research aims to remedy this neglect by shedding light on salesperson brand attachment. A qualitative study first examines the prevalence of attachment and uncovers several potential antecedents. Two follow-up empirical studies show that identification and psychological ownership are significant predictors of salesperson brand attachment. Informed by this research, managers can encourage brand attachment, with the end goal of increasing salesperson effort and ultimately performance, by increasing feelings of identification and psychological ownership among salespeople. This impact is particularly notable among brands with low market share, which are often a key concern of managers. The findings provide novel insights into how attachment affects sales representatives, as well as potential methods to cultivate such an attachment.  相似文献

Parent and teacher reports of symptoms of Attention Deficit Hyperactivity Disorder (ADHD) in children often differ from each other. These informant report differences may occur in systematic ways that vary by child socioeconomic status (SES) and race, but little is known about how SES and race together relate to parent and teacher report of ADHD symptoms in school-aged children. We examined the relationship between child SES, child race and parent and teacher reports of ADHD symptoms in two samples of school-aged Caucasian and African American children being evaluated for ADHD (N = 1056; N = 317). Multivariate regression was used to predict parent and teacher reports of ADHD symptoms from child SES, race, age, gender and interaction terms. The Wald test of parameter constraints was used to test the contrast between the predictors of interest and parent and teacher report of symptoms. In the second sample, we also examined observer report measures of ADHD symptoms during one-to-one testing and in the classroom. In both samples, lower SES was associated with higher levels of inattention symptoms, as reported by teachers, but not by parents. Lower SES was also associated with higher levels of hyperactivity/impulsivity symptoms, as reported by both teachers and parents. African American race was associated with higher levels of inattention and hyperactivity/impulsivity symptoms reported by teachers than reported by parents. Observer report measures showed a different pattern of associations with SES and race. Investigating how children’s SES and race influence cross-informant agreement on ratings of children’s behavior might lead to the development of better assessment practices and more accurate diagnoses for diverse child populations.  相似文献

Our longitudinal study contributes to the body of literature on depression in childhood by examining potential protective factors. We investigated the influence of maternal depressive symptoms on child depressive symptoms at early school age and its gender-specific moderation by children’s narrative representations of the maternal figure, over and above children’s own depressive symptoms at preschool age. Children’s narrative representations were assessed using the MacArthur Story Stem Battery in 170 preschool children (92 girls; 54.1?%) oversampled for internalizing symptoms. Children’s depressive symptoms were assessed at preschool age (Time 1; 4–6 years) and at early school age (Time 2; 6–8 years) by maternal report; mothers’ depressive symptoms were assessed at Time 1. The results showed that for boys, only their own depressive symptoms at Time 1 predicted their depressive symptoms at Time 2. For girls, maternal depressive symptoms were a significant risk factor for their own depressive symptoms at Time 2. Regarding this association, we also found a moderation effect: girls with more positive narrative representations of the maternal figure showed a reduced negative impact of maternal depressive symptoms on their own depressive symptoms at Time 2. This implies that clinical practice should screen a child for early depressive symptoms, especially if the mother displays depressive symptoms. Clinicians might also assess children’s inner working models, which can serve as a protective factor.  相似文献

Use of the Five Minute Speech Sample in parenting research has become increasingly widespread in recent years, raising important questions about how it maps onto other more established methods for assessing parent–child dynamics. Given the historical emphasis on direct observation as a gold standard in such assessment, our aim was to examine associations between the Five Minute Speech Sample and direct observational coding of parent–child interactions, and to evaluate the assumption that the Five Minute Speech Sample reflects moment-to-moment exchanges between parents and children. A systematic search of three databases conducted identified 25 relevant studies (total N?=?2945 child participants). These studies focused largely on four distinct systems for coding the Five Minute Speech Sample, and reported on distinct developmental periods ranging from infancy (17 months) through to adolescence (17 years). In 20 of 25 studies, the Five Minute Speech Sample was significantly associated with observations of parent–child interactions. These associations were apparent in all age groups examined, yet findings for fathers were somewhat more mixed than mothers. Available evidence suggests that the Five Minute Speech Sample holds strong potential as a brief but richly informative tool for indexing parent–child dynamics—particularly affective dimensions of the parent–child relationship—in both research and clinical contexts.  相似文献

Although counselors receive training in both diagnosis and cultural foundations of human behavior, little literature or research integrates these 2 areas in order to facilitate culturally sensitive diagnostic practices. The authors attempt to rectify that lack by providing a review of the literature on the controversies associated with traditional diagnosis of cultural groups that differ from the dominant culture. Practical guidelines for culturally sensitive diagnosis are provided.  相似文献

Zusammenfassung Der Beitrag beschäftigt sich mit den Chancen und Risiken von neuen Technologien und computervermittelter Kommunikation in der psychosozialen Versorgung. Es wird zunächst ein Überblick über die technischen Voraussetzungen sowie die gesetzlichen und ethischen Bedingungen gegeben, die den Rahmen für die Möglichkeiten und Grenzen setzen. Im Anschluss daran werden exemplarisch einige Ansätze vorgestellt, die bereits der Forderung nach Evaluation nachkommen. Dabei wird zwischen Offline- und Onlineangeboten unterschieden. Es wird diskutiert, wie zukünftige Entwicklungen für eine Optimierung der Versorgung genutzt werden können, beispielsweise im Rahmen von gestuften Behandlungskonzepten. Schließlich werden Perspektiven erörtert, die der Einsatz neuer Technologien für die Psychotherapieforschung eröffnet.  相似文献

Young children develop social and emotional competence through interactions with others in the two major contexts in which they spend time: home and preschool. This study examined whether parenting stress in the home context is related to the children's behaviour while in preschool. Previous research has suggested that parenting stress negatively influences parenting behaviour, which in turn has been shown to impact children's development. This study examined the direct relationship between parenting stress and children's behaviour in two types of preschool programmes: private day care centres and Head Start. Parenting stress was significantly related to teacher ratings of social competence, internalizing behaviours, and externalizing behaviours, and the effects of parenting behaviour do not appear to mediate this relationship. Parenting stress was most strongly related to children's social competence. Parents' reports of expectations for their child's behaviour appear to weakly moderate the relationship between externalizing behaviour and parenting stress. This study suggests that examination of a parent's level of stress, in addition to parenting practices, may be important in research and interventions with preschool children's behaviour and social competence.
