We examined a new structured interview of parent?Cchild conflict that assesses parent and child perceptions of behavioral conflict about daily life topics (e.g., doing chores, homework), and whether discrepancies exist on beliefs about these topics. In a sample of 100 parents and children ages 10 to 17?years (M?=?13.5?years, 52 males, 57?% African-American), informants could reliably distinguish between perceived behavioral conflicts and perceived discrepant beliefs about topics. These scores were also significantly related to questionnaire reports of parent?Cchild conflict. Parent and child questionnaire reports did not significantly differ, yet on the structured interview, parents reported significantly greater levels of perceived conflict and discrepant beliefs relative to child reports. Additionally, structured interview reports of conflict demonstrated incremental validity by relating to child self-reports of delinquent behaviors, when accounting for questionnaire conflict reports. The findings have implications for increasing understanding of the links between parent?Cchild conflict and psychosocial outcomes.  相似文献

We examined self-reported and parent-reported adolescent social anxiety symptoms and objective baseline measures of psychophysiological flexibility in 62 families. Measures completed by 31 adolescents referred for a clinical screening evaluation for social anxiety were compared to an age- and gender-matched community control sample of 31 adolescents (total sample: age range 14 to 17?years; 22 boys and 40 girls; M?=?15.32?years; SD?=?1.1). Clinic referred adolescents reported significantly fewer social anxiety symptoms than parents reported about adolescents. Further, for all adolescents, self-reported social anxiety symptoms exhibited low correspondence with objective psychophysiological measures. Yet, both measures uniquely discriminated between adolescents on whether they were clinic referred for a social anxiety screening. Further, adolescent self-reported social anxiety symptoms exhibited high levels of internal consistency and convergent validity. Findings indicate that researchers and practitioners should refrain from using disagreements between adolescent self-reports and other measures (e.g., parent report, objective measures) as indicators of the veracity of adolescent self-reports.  相似文献

In decision making, people can focus on decisional outcomes (outcome focus), but they can also focus on gaining knowledge about the decisional domain (learning focus). Furthermore, people differ in the strength of their epistemic needs—their preference for developing a rich and accurate understanding of the world. We invoke the regulatory fit theory to predict that higher epistemic needs better fit a learning focus than lower epistemic needs, resulting in a greater increase in valuation of the chosen option when a learning rather than an outcome focus is induced. This general hypothesis was tested and supported in three studies, each focusing on a different proxy to epistemic needs. Thus, individuals experienced greater value when they had lower expertise (Study 1), higher need for assessment (Study 2), and higher need for cognition (Study 3) when a learning rather than an outcome focus was induced. Implications for work on epistemic needs, regulatory fit theory, and decision‐making practice are discussed. Copyright © 2011 John Wiley & Sons, Ltd.  相似文献

Mother's open-ended questions and elaborative statements during reminiscing were analysed for their content (child agency, co-agency, non-social, and social context) in three cultural contexts. Participants were 115 mothers and their 4-year-old children: 35 dyads from Berlin, Germany, 42 from Stockholm, Sweden, and 38 from Tallinn, Estonia. Across samples the most prominent content was talk about non-social context followed by co-agency and child agency. Tallinn mothers asked the children to talk about themselves, and Berlin mothers asked the children to talk about themselves together with other people, more frequently than they talked about these contents themselves. The content was related to the cultural orientations of mothers assessed through questionnaires: the Berlin mothers whose independence/ interdependence ratio was higher talked less about other people and asked the children fewer questions about other people; the Stockholm mothers with a higher independence/interdependence ratio talked more about child agency. In Tallinn both correlations existed on a trend level. The results are discussed in the light of common conversational practices and mothers' orientation to independence and interdependence in these cultural contexts.  相似文献

In the present study, we investigated the functional characteristics of task sets that were never applied before and were formed only on the basis of instructions. We tested if such task sets could elicit a task-rule congruency effect, which implies the automatic activation of responses in the context of another task. To this end, a novel procedure was developed that revealed instruction-based task-rule congruency effects in 2 experiments. Although the effect seems quite general (Experiment 1), it still necessitates the formation of a task set, as it cannot be induced by the mere maintenance of instructions in declarative working memory (Experiment 2). We conclude that a task set representing only key features of an upcoming task can be formed on the basis of instructions alone to such a degree that it can automatically trigger a response tendency in another task. Implications of our results for the impact of instructions on performance in general and for the occurrence of task-rule congruency effects in particular are discussed.

In a sample of 200 individuals diagnosed with body dysmorphic disorder (BDD), we utilized the interpersonal-psychological theory for suicide as a framework to examine BDD behaviors that might be associated with suicide risk, insofar as they might increase the acquired capability for suicide. We predicted that physically painful BDD behaviors (e.g., cosmetic surgery, restrictive eating) would be associated with suicide attempts but not suicide-related ideation because these behaviors increase capability for, but not thoughts about, suicide. Our hypothesis was partially confirmed, as BDD-related restrictive food intake was associated with suicide attempts (but not suicide-related ideation) even after controlling for numerous covariates.  相似文献

A long-debated question in the philosophy of health, and contingent disciplines, is the extent to which wise clinical practice ("clinical wisdom") is, or could be, compatible with empirically validated medicine ("evidence-based medicine"--EBM). Here we respond to Baum-Baicker and Sisti, who not only suggest that these two types of knowledge are divided due to their differing sources, but also that EBM can sometimes even hurt wise clinical practice. We argue that the distinction between EBM and clinical wisdom is poorly defined, unsupported by the methodology employed, and ultimately incorrect; crucial differences exist, we argue, not in the source of a particular piece of clinical knowledge, but in its dependability. In light of this subtle but fundamental revision, we explain how clinical wisdom and EBM are--by necessity--complementary, rather than in conflict. We elaborate on how recognizing this relationship can have far-reaching implications for the domains of clinical practice, medical education, and health policy.  相似文献

A neurobiological account of cognitive vulnerability for recurrent depression is presented based on recent developments of resting state neural networks. We propose that alterations in the interplay between task positive (TP) and task negative (TN) elements of the Default Mode Network (DMN) act as a neurobiological risk factor for recurrent depression mediated by cognitive mechanisms. In the framework, depression is characterized by an imbalance between TN-TP components leading to an overpowering of TP by TN activity. The TN-TP imbalance is associated with a dysfunctional internally-focused cognitive style as well as a failure to attenuate TN activity in the transition from rest to task. Thus we propose the TN-TP imbalance as overarching neural mechanism involved in crucial cognitive risk factors for recurrent depression, namely rumination, impaired attentional control, and cognitive reactivity. During remission the TN-TP imbalance persists predisposing to vulnerability of recurrent depression. Empirical data to support this model is reviewed. Finally, we specify how this framework can guide future research efforts.  相似文献

Social stress has been related to both physiological and psychological responses. The recovery of stress is influenced by the way environmental information is processed, i.e., what information is attended to and how it is interpreted. The present study investigated the effect of attention modification training on physiological stress recovery following induced stress. A group of applicants preparing for a job interview were randomly allocated to an attention training condition versus a control condition. Afterwards, they were asked to give an artificial job interview to a real life jury while being videotaped. Participants in both conditions showed decreased heart rate variability during the job interview, which indicates an overall physiological stress response. However, during a 30-minute follow-up period after the training, indices of heart rate variability showed improved stress recovery only in the attention training condition. Attentional training is proposed as a promising strategy to prevent enduring stress reactions.  相似文献
