AbstractIn intervention studies having multiple outcomes, researchers often use a series of univariate tests (e.g., ANOVAs) to assess group mean differences. Previous research found that this approach properly controls Type I error and generally provides greater power compared to MANOVA, especially under realistic effect size and correlation combinations. However, when group differences are assessed for a specific outcome, these procedures are strictly univariate and do not consider the outcome correlations, which may be problematic with missing outcome data. Linear mixed or multivariate multilevel models (MVMMs), implemented with maximum likelihood estimation, present an alternative analysis option where outcome correlations are taken into account when specific group mean differences are estimated. In this study, we use simulation methods to compare the performance of separate independent samples t tests estimated with ordinary least squares and analogous t tests from MVMMs to assess two-group mean differences with multiple outcomes under small sample and missingness conditions. Study results indicated that a MVMM implemented with restricted maximum likelihood estimation combined with the Kenward–Roger correction had the best performance. Therefore, for intervention studies with small N and normally distributed multivariate outcomes, the Kenward–Roger procedure is recommended over traditional methods and conventional MVMM analyses, particularly with incomplete data. 相似文献

ABSTRACTChildren across the world report similar spiritual experiences. Empirical studies suggest that most resonate with the children’s traditions; a finding which should, in theory, afford them a safe spiritual space. However, a number of factors can situate them in a less certain place. The paper uses the metaphors of trees imbued with different shades of light, from the vivid, shimmering and opaque to the invisible, to illustrate the types of spiritual spaces in which children find themselves. Their location is shaped in part by connection or disconnection with traditions, alongside wider cultural forces. Three navigation tools are used to show how children may move between these spaces: the spiritual experience and its relationship with traditions; the influences of multidisciplinary approaches; and children’s perceptions of their experiences. The paper concludes that these metaphors and tools may be a useful way to understand the spiritual spaces in which children find themselves. 相似文献

Past studies found that, for preschoolers, a story specifying a situational cause and behavioural consequence is a better cue to fear and disgust than is the facial expression of those two emotions, but the facial expressions used were static. Two studies (Study 1: N = 68, 36–68 months; Study 2: N = 72, 49–90 months) tested whether this effect could be reversed when the expressions were dynamic and included facial, postural, and vocal cues. Children freely labelled emotions in three conditions: story, still face, and dynamic expression. Story remained a better cue than still face or dynamic expression for fear and disgust and also for the later emerging emotions of embarrassment and pride. 相似文献

Attentional problems are commonly reported as a feature of the behavioural profile in both Williams syndrome (WS) and Down's syndrome (DS). Recent studies have begun to investigate these impairments empirically, acknowledging the need for an approach that considers cross‐syndrome comparisons and developmental changes across the different component functions of attention. The present study assessed children with WS and DS using a new preschool attention battery (ECAB: early childhood attention battery), designed to be suitable for mental age 3–6 years including groups with developmental disorders. The ECAB has the advantage of giving an individual profile of attentional abilities for each child, covering different components of attention. In relation to test norms for their mental age, both groups showed a profile of strengths and weaknesses in the attention domain. Both syndrome groups performed relatively well on tests of sustained attention and poorly on aspects of selective attention and attentional control (executive function). The DS group showed a specific strength in auditory sustained attention, whilst the WS group showed a particular deficit in visuo‐spatial response control. There was also evidence for considerable differences in the developmental trajectory of these abilities across the two groups. The results provide evidence for syndrome‐specific patterns of impairment, and distinct profiles of strengths and weaknesses that may be useful in understanding the nature of everyday attention difficulties in these groups and tailoring interventions to meet these needs. 相似文献

This article introduces a new battery of attention tests for typically developing and atypically developing children with a mental age of 3–6 years. In the light of adult and child studies supporting a model of distinct networks for specific attentional operations, tests in the current battery were selected with the aim of measuring functions of selective attention, sustained attention and attentional control (executive function). Normative data were collected from 154 typically developing children aged 3–6 years and examined using exploratory factor analysis to determine latent constructs underlying test performance. This analysis suggested increasing differentiation of attention functions over the age range, with support for the hypothesized three‐factor model only after 4½ years of age. Additional analyses supported the validity of the new attention battery with respect to (1) parent/teacher report measures of everyday attention behaviour and (2) later performance on the Test of Everyday Attention for Children (TEA‐Ch), a battery designed for children aged 6–16 years. The results show the developing differentiation of attention functions and support the ecological and predictive validity of the battery as providing early performance‐based measures of attention and an attention ‘profile’ for each individual child, which may aid characterization and remediation of neurodevelopmental disorders. 相似文献
