As research continues to document differences in the prevalence of mental health problems such as depression across racial/ethnic
groups, the issue of measurement equivalence becomes increasingly important to address. The Mood and Feelings Questionnaire
(MFQ) is a widely used screening tool for child and adolescent depression. This study applied a differential item functioning
(DIF) framework to data from a sample of 6th and 8th grade students in the Seattle Public School District (N = 3,593) to investigate the measurement equivalence of the MFQ. Several items in the MFQ were found to have DIF, but this
DIF was associated with negligible individual- or group-level impact. These results suggest that differences in MFQ scores
across groups are unlikely to be caused by measurement non-equivalence. 相似文献

For parents of infants and toddlers receiving a diagnosis of disability, a variety of responses may result. Yet, little is known about the specific ways families cope with the initial diagnosis. This qualitative study investigated 6 mothers' memories of their children's diagnoses. Mothers described their use of both palliative strategies (denying, questioning, and wishful thinking) and problem‐solving strategies (searching for information, seeking social support, reframing, and seeking spiritual support) to cope with their children's initial diagnoses. The results of this study may improve professionals' understanding of parents' need for information and support at the time of initial diagnosis. 相似文献

Excessive fear of movement-related pain (FMRP), and its associated avoidance behavior, is considered a major risk factor for disability in chronic musculoskeletal pain. The current study aimed to investigate whether engaging in safety behavior, conceptualized as an avoidance response, hampers the extinction of FMRP. In a differential conditioning paradigm, we used joystick movements as conditioned stimuli (CSs) and a painful electrocutaneous stimulus as the unconditioned stimulus (US). In the Safety group, participants received the opportunity to avoid the pain-US by pressing a safety button during the extinction phase, whereas in the Control group, this option was not included. In a subsequent test phase, this safety button was no longer available. In two experiments, results demonstrate successful acquisition and extinction. Retrospective FMRP ratings in both experiments revealed a return of fear of pain in the test phase in the Safety group, but not in the Control group. In Experiment 1, mean eyeblink startle reflex amplitudes partly corroborated the self-report findings on fear of pain. The present results suggest that performing safety behavior during cognitive-behavioral interventions, i.e., exposure, might increase the risk of a return of FMRP. 相似文献

In this paper I consider two accounts of scientific discovery, Robert Hudson’s and Peter Achinstein’s. I assess their relative
success and I show that while both approaches are similar in promising ways, and address experimental discoveries well, they
could address the concerns of the discovery sceptic more explicitly than they do. I also explore the implications of their
inability to address purely theoretical discoveries, such as those often made in mathematical physics. I do so by showing
that extending Hudson’s or Achinstein’s account to such cases can sometimes provide a misleading analysis about who ought
to be credited as a discoverer. In the final sections of the paper I work out some revisions to the Hudson/Achinstein account
by drawing from a so-called structural realist view of theory change. Finally, I show how such a modified account of discovery
can answer sceptical critics such as Musgrave or Woolgar without producing misleading analyses about who ought to receive
credit as a discoverer in cases from the mathematical sciences. I illustrate the usefulness of this approach by providing
an analysis of the case of the discovery of the Casimir effect. 相似文献

Purpose
This study investigated the relationship between self-reported stuttering severity ratings and educational attainment.Method
Participants were 147 adults seeking treatment for stuttering. At pretreatment assessment, each participant reported the highest educational level they had attained and rated their typical and worst stuttering severity on a 9-point scale for a range of speaking situations. These included: (1) talking with a family member, (2) talking with a familiar person, not a family member, (3) talking in a group of people, (4) talking with a stranger, (5) talking with an authority figure such as a work manager or teacher, (6) talking on the telephone, (7) ordering food or drink, and (8) giving their name and address.Results
There was a significant negative relationship between highest educational achievement and mean self-reported stuttering severity rating for the eight situations.Conclusions
Future research is needed to investigate how this result should be addressed in educational institutions.Educational objectives: The reader will be able to: (1) describe the negative effects of stuttering through childhood to adulthood; (2) identify some of the negative consequences associated with stuttering on peer and teacher relationships, and academic performance at school; and (3) summarise the relationship between stuttering severity and educational attainment. 相似文献147.

Executive functions (EFs; e.g. working memory, inhibitory control) are mediated by the prefrontal cortex and associated with optimal cognitive and socio‐emotional development. This study provides the first concurrent analysis of the relative contributions of maternal EF and caregiving to child EF. A group of children and their mothers (n = 62) completed age‐appropriate interaction (10, 24, 36 months) and EF tasks (child: 24, 36, and 48 months). Regression analyses revealed that by 36 months of age, maternal EF and negative caregiving behaviors accounted for unique variance in child EF, above and beyond maternal education and child verbal ability. These findings were confirmed when using an early child EF composite‐our most reliable measure of EF – and a similar pattern was found when controlling for stability in child EF. Furthermore, there was evidence that maternal EF had significant indirect effects on changes in child EF through maternal caregiving. At 24 months, EF was associated with maternal EF, but not negative caregiving behaviors. Taken together, these findings suggest that links between negative caregiving and child EF are increasingly manifested during early childhood. Although maternal EF and negative caregiving are related, they provide unique information about the development of child EF.

In many jurisdictions, police instruct a witness, before presenting a photo line‐up, that the suspect's appearance may be different in the photo than it was at the time of the crime. The experiments reported here examine the impact of this ‘appearance‐change instruction’ (ACI), exploring its effects with different crimes, perpetrators, line‐ups, and different phrasings of the ACI. The data indicate that the ACI increases witnesses' willingness to make a choice from a line‐up but does not increase accuracy. Copyright © 2013 John Wiley & Sons, Ltd. 相似文献
