Despite the well‐established links between couple relationship quality and healthy family functioning, and burgeoning evidence from the international intervention field, there is little or no evidence of the efficacy of couples‐based interventions from the United Kingdom (U.K.). This study explored whether the Parents as Partners (PasP) program, a group‐based intervention developed in the United States, brought about the same benefits in the U.K. The evaluation is based on 97 couples with children from communities with high levels of need, recruited to PasP because they are at high risk for parent and child psychopathology. Both mothers and fathers completed self‐report questionnaires assessing parents’ psychological distress, parenting stress, couple relationship quality and conflict, fathers’ involvement in child care and, importantly, children's adjustment. Multilevel modeling analysis comparing parents’ responses pre‐ and postintervention not only showed substantial improvements for both parents on multiple measures of couple relationship quality, but also improvements in parent and child psychopathology. Analyses also indicated most substantial benefits for couples displaying poorest functioning at baseline. The findings provide initial evidence for the successful implementation of PasP, an American‐origin program, in the U.K., and add support for the concept of the couple relationship as a resource by which to strengthen families.  相似文献

The current study examined the outcome of presenting multiple secondary targets in learning trials for individuals with autism spectrum disorder. We compared conditions in which (a) a secondary target was presented in the antecedent and consequence of trials, (b) two secondary targets were presented in the consequence of trials, (c) one secondary target was presented in the consequence of each trial, and (d) no additional targets were presented trials. The participants acquired the majority of secondary targets. Presenting one or multiple secondary targets per trial, regardless of the location of these secondary targets, increased the efficiency of instruction in comparison to a condition with no secondary target.  相似文献

We replicated Fritz, Iwata, Hammond, and Bloom (2013) by evaluating the efficacy of an experimental methodology to identify precursors to aggression displayed by an adolescent with autism spectrum disorder. Using their trial‐based precursor analysis, we identified seven precursors to aggression. Next, we compared the outcomes of separate precursor and aggression functional analyses and showed that both precursors and aggression were multiply controlled by the same variables.  相似文献

The paper argues that knowledge is not closed under logical inference. The argument proceeds from the openness of evidential support and the dependence of empirical knowledge on evidence, to the conclusion that knowledge is open. Without attempting to provide a full-fledged theory of evidence, we show that on the modest assumption that evidence cannot support both a proposition and its negation, or, alternatively, that information that reduces the probability of a proposition cannot constitute evidence for its truth, the relation of evidential support is not closed under known entailment. Therefore the evidence-for relation is deductively open regardless of whether evidence is probabilistic or not. Given even a weak dependence of empirical knowledge on evidence, we argue that empirical knowledge is also open. On this basis, we also respond to the strongest argument in support of knowledge closure (Hawthorne 2004a). Finally, we present a number of significant benefits of our position, namely, offering a unified explanation for a range of epistemological puzzles.  相似文献

The present study aimed to examine how changes in positive and negative affect and their interaction predict changes in felt age in a longitudinal design of two waves drawn from the Health and Retirement Study (HRS). Participants (n = 4174) at an average age of 67.97 completed the 2008 and 2012 left behind questionnaire of the HRS. Our results showed that an increase in positive affect and a decrease in negative affect from Wave 1 to Wave 2 predicted an accelerated decrease in felt age. There was an interaction effect showing that for those with an increase in negative affect, a higher change in positive affect predicted reduced odds for accelerated increase in felt age. To conclude, improving favorable change in the combination between positive and negative affect might in turn relate to the individual’s self-perceptions of aging, in the second half of life.  相似文献

In a randomised wait list-controlled trial with repeated measures pre-, post- and follow-up design, participants (N = 109) with a current self-reported diagnosis of an anxiety disorder and/or depression, took part in an internet-based study. After completing a three-week gratitude diary returning participants had lower scores on measures of depression, anxiety, stress and perceived sleep difficulties and higher scores on a measure of subjective well-being than immediately pre-intervention. At three-week follow-up depression and sleep scores for returning participants were no longer significantly different from pre-intervention, however, improvements for subjective well-being and stress at post-intervention were maintained. At follow-up anxiety scores had not only been maintained but had improved significantly beyond post-intervention results. Intention to treat analyses were conducted and provided support for most completer results. Differences between the two sets of analyses are discussed below. This trial provides support for the use of gratitude diaries as an intervention with distressed populations.  相似文献

Dostoevskij’s underground parody of confession paradoxically recovers an Orthodox morality by constructing an unorthodox model of authority and authorship. The authenticity and authority of underground discourse are both contingent on self-conscious parody, which also mediates Orthodox community or sobornost’. This essay critically reconsiders ethical, aesthetic and cultural dimensions of the self-conscious interpolation of literary and religious discourses in Dostoevskij’s Notes from Underground. Arguing with and against Bakhtinian readings, it re-examines the underground narrator’s secularized, Romanticized sensibilities, cynical critique of humanism, sacrilegious modes of laughter, usurpation of authority, internalization of dialogue, literary stylization and parody, aesthetic and moral self-critique, and, finally, insistence on “a new word.”  相似文献

A brief motivational intervention with 117 homeless adolescents was evaluated using a randomized design and 3-month follow-up. The intervention was designed to raise youths' concerns about their substance use, support harm reduction, and encourage greater service utilization at a collaborating agency. The study was designed to strengthen initial promising results of an earlier study (P. L. Peterson, J. S. Baer, E. A. Wells, J. A. Ginzler, & S. B. Garrett, 2006). Several modifications in the clinical protocol were included to enhance engagement with the intervention. Analyses revealed no significant benefits for intervention participants when homeless youths' substance use rates were compared with those of control participants. Service utilization during the intervention period increased for those receiving the intervention but returned to baseline levels at follow-up. Participants reported overall reductions in substance use over time. Differences between sampling methods for the current and previous study are discussed, as are the limitations of brief interventions with this population. Future research needs to elucidate mechanisms of change and service engagement for highly vulnerable youth.  相似文献

The present study investigated the pathways between attention problems and depressive symptoms, particularly the role of academic incompetence, among a community sample of urban African American children. Results supported the hypothesized path models from inattention to depressive symptoms for girls and boys. Academic performance in the spring of first grade mediated the relationship between inattention in fall of first grade and depressive symptoms in spring of 3rd grade. The effects held when controlling for conduct problems and academic competence in first grade suggesting the path was specific to attention problems rather than a more general externalizing or school readiness pathway. Implications for designing interventions and prevention strategies for children with attention problems and depressive symptoms are discussed.  相似文献
