The purposes of this study were to: (1) Assess child abuse professionals’ and nonprofessionals’ knowledge of scientific research findings that are relevant to forensic child sexual abuse (CSA) evaluations and (2) describe associations between child abuse professionals’ levels of research knowledge and their education and experience. An 18-item multiple-choice test was administered to 188 child abuse professionals and 457 nonprofessionals (undergraduate college students) in Brazil and the United States. The nonprofessionals’ average percent correct, M = 44%, was not significantly different than what would be expected for random guessing (45%). The professionals’ average percent correct, M = 55%, was higher than that of nonprofessionals and random guessing (both ps < .001). The average percent correct score for the US-sample psychologists, M = 76%, was higher than the average score of the other professionals, M = 51%, p < .001. Professionals’ educational level, as measured by the highest academic degree obtained, was positively associated with percent correct scores, Spearman's ρ = .46, p < .001. Controlling for educational attainment, professional experience, as measured by the total number of CSA evaluations performed, was weakly associated with percent correct scores, partial r = .15, p = .04. Percent correct scores were low for both nonprofessionals and professionals. Most of the participants in this study were uninformed or misinformed about scientific research findings that are important for conducting optimal forensic CSA evaluations and for making accurate judgments about the validity of sexual abuse allegations.  相似文献

Studies suggest prenatal cannabis exposure is associated with mood/behavioral problems in children. However, it is unclear if targeting modifiable domains like sleep behaviors would improve outcomes in exposed youth. Using a causal inference framework, the effect of changing sleep-hours on changing internalizing/externalizing problems in children was examined using the Adolescent Brain Cognitive Development™ study baseline (ages 9–10; collected during 2016–2018) and year-1 follow-up data (N = 9825; 4663 female; 5196 white). Average treatment effects (ATE) indicated that more sleep predicted less internalizing (ATE = −.34, SE = .08, p < .001) and externalizing (ATE = −.29, SE = .07, p < .001) problems over time. However, prenatal cannabis exposure moderated the ATE on internalizing (conditional-ATE = .91, SE = .39, p = .019), whereby participants with exposure (n = 605) did not show any effect of changing sleep-hours on mood (B = .09, SE = .24).  相似文献

This study developed three forms of computer-based multimedia, including Static Graphics (SG), Simple Learner-Pacing Animation (SLPA), and Full Learner-Pacing Animation (FLPA), to assist students in learning topographic measuring. The interactive design of FLPA allowed students to physically manipulate the virtual measuring mechanism, rather than passively observe dynamic or static images. The students were randomly assigned to different multimedia groups. The results of a one-way ANOVA analysis indicated that (1) there was a significant difference with a large effect size (f = .69) in mental effort ratings among three groups, and the post-hoc test indicated that FLPA imposed less cognitive load on students than did SG (p = .007); (2) the differences of practical performance scores among groups reached the statistic significant level with a large effect size (f = .76), and the post-hoc test indicated that FLPA fostered better learning outcomes than both SLPA and SG (p = .004 and p = .05, respectively); (3) the difference in instructional efficiency that was computed by the z-score combination of students’ mental effort ratings and practical performance scores among the three groups obtained the statistic significant level with a large effect size (f = .79), and the post-hoc test indicated that FLPA brought students higher instructional efficiency than those of both SLPA and SG (p = .01 and .005, respectively); (4) no significant effect was found in instructional time-spans between groups (p = .637). Overall, FLPA was recommended as the best multimedia form to facilitate topographic measurement learning. The implications of instructional multimedia design were discussed from the perspective of cognitive load theory.  相似文献

The associations between trajectories of child care quality from ages 2 to 4 years and children's cognitive performance at 4 years (= 250) were tested. Distinct quality trajectories were identified: low and high ascending Teaching and Interactions trajectory; low and high Provision for Learning trajectory. Membership in the high ascending Teaching and Interactions trajectory was associated with better numeracy (effect size [ES] = .39, confidence interval [CI] = .21–.66), receptive vocabulary (ES = .41, CI = .14–.68), and school readiness (ES = .32, CI = .06–.58). The results suggest that a pattern of increasing quality of teacher–child interactions during the preschool years, particularly with regard to supporting the development of language, has a moderate impact on children's cognitive development.  相似文献

Building on longitudinal findings of linkages between aspects of teachers' language during instruction and children's use of mnemonic strategies, this investigation was designed to examine experimentally the impact of instruction on memory development. First and second graders (= 54, Mage = 7 years) were randomly assigned to a science unit that varied only in teachers' use of memory‐relevant language. Pretest, posttest, and 1‐month follow‐up assessments revealed that although all participating children learned new information as a result of instruction, those exposed to memory rich teaching exhibited greater levels of strategic knowledge and engaged in more sophisticated strategy use in a memory task involving instructional content than did students exposed to low memory instruction. The findings provide support for a causal linkage between teachers' language and children's strategic efforts.  相似文献

The Language ENvironment Analysis system (LENA) records children’s language environment and provides an automatic estimate of adult–child conversational turn count (CTC). The present study compares LENA’s CTC estimate to manually coded CTC on a sample of 70 English-speaking infants recorded longitudinally at 6, 10, 14, 18, and 24 months of age. At each age, LENA’s CTC was significantly higher than manually coded CTC (all ps < .001, Cohen’s ds: 0.9–2.05), with the largest discrepancies between the two methods observed at younger ages. The Limits of Agreement Analyses confirm wide disagreements between the two methods, highlighting potential problems with automatic measurement of parent–infant verbal interaction. These findings suggest that future studies should validate LENA’s CTC estimates with manual coding.  相似文献

This study tested the impact of child‐directed language input on language development in Spanish–English bilingual infants (= 25, 11‐ and 14‐month‐olds from the Seattle metropolitan area), across languages and independently for each language, controlling for socioeconomic status. Language input was characterized by social interaction variables, defined in terms of speech style (“parentese” vs. standard speech) and social context (one‐on‐one vs. group). Correlations between parentese one‐on‐one and productive vocabulary at 24 months (= 18) were found across languages and in each language independently. Differences are highlighted between previously published monolingual samples, which used the same methods as the current study of bilingual infants. The results also suggest cultural effects on language input and language development in bilingual and bicultural infants.  相似文献

The present article reports results of a real‐world effectiveness trial conducted in Denmark with six thousand four hundred eighty‐three 3‐ to 6‐year‐olds designed to improve children's language and preliteracy skills. Children in 144 child cares were assigned to a control condition or one of three planned variations of a 20‐week storybook‐based intervention: a base intervention and two enhanced versions featuring extended professional development for educators or a home‐based program for parents. Pre‐ to posttest comparisons revealed a significant impact of all three interventions for preliteracy skills (= .21–.27) but not language skills (d = .04–.16), with little differentiation among the three variations. Fidelity, indexed by number of lessons delivered, was a significant predictor of most outcomes. Implications for real‐world research and practice are considered.  相似文献

ABSTRACT

The Powerful Tools for Caregivers (PTC) program is designed to help caregivers develop skills to improve their self-efficacy in caregiving. To demonstrate the effectiveness of the PTC program in Boise, Idaho, the program’s pre-survey (n = 277), end-of-program survey (n = 131), and 6-month follow-up post-survey data (n = 100) collected between 2011 and 2017 were analyzed in this study. The end-of-program survey data indicated that caregivers viewed the quality of the program to be excellent and that all of them felt more confident as a caregiver. Factor analysis and reliability testing on the pre-survey data confirmed that seven questions included in the pre- and 6-month follow-up post-survey instruments reliably measured a single factor named as caregiver confidence. A paired samples t-test on 76 complete sets of pre- and 6-month follow-up post-survey data on the seven questions revealed that caregivers improved their confidence in caregiving to a statistically significant level (p < .001, d = 45). Additional paired samples t-tests on each of the seven questions with the Bonferroni correction showed statistically significant improvements in three areas: making tough decisions (p < .001, d = .53), coping with emotions (p < .001, d = .54), and using stress-reducing activities (p < .007, d = .33). Caregivers experienced the greatest improvement in their confidence in making tough decisions. Despite these significant improvements, caregivers still struggled with finding ways to reduce stress and manage their emotions associated with caregiving as shown by the lowest pre- and 6-month follow-up post-survey scores. In addition to the study results, several considerations when synthesizing PTC research results are discussed.  相似文献

Interventions that train parents to share picture books with children are seen as a strategy for supporting child language development. We conducted meta-analyses using robust variance estimation modeling on results from 19 RCTs (Ntotal = 2,594; Mchildage = 1–6 years). Overall, book-sharing interventions had a small sized effect on both expressive language (= 0.41) and receptive language (= 0.26). They had a large effect on caregiver book-sharing competence (= 1.01). The impact of the intervention on child language was moderated by intervention dosage, with lower dosage associated with a minimal impact. Child age and caregiver education level were unrelated to child outcome. This review and meta-analysis confirms the promise of book-sharing interventions for enhancing and accelerating child language development.  相似文献

The self‐reference effect in memory is the advantage for information encoded about self, relative to other people. The early development of this effect was explored here using a concrete encoding paradigm. Trials comprised presentation of a self‐ or other‐image paired with a concrete object. In Study 1, 4‐ to 6‐year‐old children (= 53) were asked in each trial whether the child pictured would like the object. Recognition memory showed an advantage for self‐paired objects. Study 2 (= 55) replicated this finding in source memory. In Study 3 (= 56), participants simply indicated object location. Again, recognition and source memory showed an advantage for self‐paired items. These findings are discussed with reference to mechanisms that ensure information of potential self‐relevance is reliably encoded.  相似文献

This study conducted two meta-analyses to synthesize the association between children’s language skills and two broad-band dimensions of psychopathology: internalizing and externalizing. Pooled estimates across 139 samples (externalizing k = 105; internalizing k = 90) and 147,305 participants (age range: 2–17 years old; mean % males: 53.75; mean % White participants: 55.59; mean % minority participants: 43.12) indicated small but significant associations between child language skills and externalizing problems (Hedges’ g = .22) and between language skills and internalizing problems (Hedges’ g = .23). The association between language difficulties and externalizing problems was stronger amongst males and in children with low versus high sociodemographic risk. Implications of the results for theory and practice are discussed.  相似文献

Writing is a critical skill for success in all areas of life, but it is one of the least taught skills in school. Teachers consistently report being unprepared to teach writing. In this study, set in a Southern U.S. boomtown, teachers received two days of practice-based professional development for a ten-week implementation of self-regulated strategy development (SRSD), an evidence-based writing intervention, to support student persuasive and informational writing as well as performance on the state standardized writing exam. This multi-site cluster randomized controlled study evaluated the effectiveness of SRSD on student writing outcomes including prompt adherence, elements, and holistic quality. Multilevel modeling analysis was used to evaluate data from 418 fourth -grade students (256 treatment, 162 control) nested across 33 classes (n = 17 treatment taught by 8 departmentalized teachers; 16 control, 9 departmentalized teachers) within 11 schools randomly assigned to condition. Teachers implemented SRSD with high fidelity (M = 92%; range 91–100%). SRSD had a statistically significant and large effect on prompt adherence (p < .001; Hedges’ g = 1.87), elements (p < .001; Hedges’ g = 0.84) and holistic scores (p < .001; Hedges’ g = 0.87), while holding gender and pretest scores constant. Effects of SRSD on all writing measures were not significantly moderated by students’ gender, students’ pretest scores, or schools’ pretest scores. There were complications with teacher observations, especially related to technology. Limitations and future directions are discussed.  相似文献

One hundred elementary‐ and middle‐school students were administered the Universal Nonverbal Intelligence Test (UNIT; B.A. Bracken & R.S. McCallum, 1998) and the Leiter International Performance Scale‐Revised (Leiter‐R; G.H. Roid & L.J. Miller, 1997). Correlations between UNIT and Leiter‐R scores were statistically significant ( p < .001), ranging from .33 to .74. The UNIT Full Scale score was 5 points higher than the Leiter‐R Full Scale score, t = 4.73, p < .001. © 2006 Wiley Periodicals, Inc. Psychol Schs 43: 143–148, 2006.  相似文献

Two experiments examined the effects of a multimedia technology referred to as “Time Compressed Animated Delivery” (TCAD), on student learning in a junior-level reproductive physiology course. In experiment 1, participating students received one of two presentations of the same instructional material: TCAD and a lecture captured on video. At the completion of each presentation a test was administered and group mean test scores computed and compared. The results were statistically significant (df = 362, t = 10.623, p < 0.05), favoring the TCAD treatment group. The effect size estimate was 1.14. In experiment 2, student learning from three groups were compared on the same reproductive physiology unit used in experiment 1: (1) TCAD, (2) TCAD without the 3-D component, and (3) video-lecture. After removal of three poor functioning items, a one-way analysis of variance was computed. The results were statistically significant (df = 2, F = 2.351, p < 0.10). Results of post hoc comparisons showed that differences in mean test scores between the TCAD and control groups were statistically significant (p < 0.05). The effect size estimate was 0.25. These findings provide preliminary evidence for use of TCAD.  相似文献

The aim of this study was to build a structural model to explore the predictors of adjustment to aging (AtA) in a community-dwelling older population. A community-dwelling sample of 1,270 older adults aged between 75 and 102 years answered a questionnaire to determine sociodemographic (sex, age, professional and marital status, education, household, adult children, family's annual income, living setting, and self-reported spirituality), lifestyle, and health-related characteristics (perceived health, recent disease, medication, and leisure). Several instruments were used to assert psychological variables, namely AtA, sense of coherence, and subjective well-being. Structural equation modeling was used to explore a structural model of the self-reported AtA, encompassing all variables. Significant predictors are self-reported spirituality (β = .816, p < .001); perceived health (β = .455, p < .001); leisure (β = .322, p < .001); professional status (β = .283, p < .001); income (β = .230, p = .035); household (β = –.208, p = .007); sense of coherence (β = ?.202, p = .004); and adult children (β = .164, p = .011). The variables explain, respectively, 60.6% of the variability of AtA. Self-reported spirituality is the strongest predictor of AtA. Other predictors are perceived health, leisure, professional status, income, household, sense of coherence, and adult children. This study emphasizes the need for deepening the variables that influence older adults’ AtA—in particular, perceived health and further lifestyle-related characteristics—as being relevant for promoting aging well in later life, within a salutogenic context for health care.  相似文献

Despite being the most prevalent form of child maltreatment, the correlates and consequences of neglect are poorly understood, particularly during early adulthood. The present multi-wave, longitudinal study sought to address this gap in this literature by examining physical and emotional neglect in emerging adults in a diverse community sample. 580 adolescents (AgeMean = 18.25; AgeSD = 0.59; 58.3% female; 31% Hispanic, 28.9% Caucasian; 26.2% African-American; 13.9% other) completed self-report measures for child maltreatment at baseline, and measures for depression, posttraumatic stress disorder, generalized anxiety disorder, and substance use every year for three years. For our analyses, we used both variable-centered (mixed-level modeling) and person-centered (latent profile analysis) analyses to best understand a) how physical and emotional neglect relate to other forms of maltreatment and b) to determine physical and emotional neglect’s unique impact on prospective mental health functioning. Our person-centered analyses revealed that a three-profile model provided the best solution for our data (“No Trauma,” “Abuse”, and “Neglect”). In longitudinal analyses, the “the neglect” group had significantly elevated scores compared to the “no trauma” group on all outcomes except alcohol use (p < 0.01). Results from our variable-centered analyses showed comparable findings between physical and emotional neglect, with higher scores corresponding to elevated symptoms of depression, PTSD, illicit substance use, and cigarette use over time (p < 0.01). In conclusion, our results suggest that early neglect-exposure poses a risk for the subsequent development of internalizing symptoms and substance use behaviors among emerging adults.  相似文献

Childhood maltreatment is known to increase the risk of future psychiatric disorders. In the present study, we explored the impact of experienced maltreatment on the prevalence and comorbidity of psychiatric disorders in a high-risk population of adolescents in residential care units. We also studied the impact of poly-victimization. The participants of the study were adolescents in residential care units in Norway (n = 335, mean age 16.8 years, girls 58.5%). A diagnostic interview (Child and Adolescent Psychiatric Assessment Interview) was used, yielding information about previous maltreatment (witnessing violence, victim of family violence, community violence, sexual abuse) and DSM-IV diagnoses present in the last three months. Exposure to maltreatment was reported by 71%, and in this group, we found significantly more Asperger's syndrome (AS) (p = .041), conduct disorder (CD) (p = .049), major depressive disorder (MDD) (p = .001), dysthymia (p = .030), general anxiety disorder (GAD) (p < .001), and having attempted suicide (p = .006). We found significantly more comorbid disorders in the maltreated group. Poly-victimization was studied by constructing a scale comprised of witnessing violence, victim of family violence, victim of sexual abuse and household dysfunction. We found that poly-victimization was associated with significantly increased risk of MDD, GAD, AS, CD, and having attempted suicide (p < .01). The complexity of the clinical outcomes revealed in this study suggest that longer-term treatment plans and follow-up by psychiatric services might be needed to a greater extend than for the rest of the child and adolescent population, and that trauma informed care is essential for adolescents in residential youth care.  相似文献

This study examined the relation of 3‐year core information‐processing abilities to lexical growth and development. The core abilities covered four domains—memory, representational competence (cross‐modal transfer), processing speed, and attention. Lexical proficiency was assessed at 3 and 13 years with the Peabody Picture Vocabulary Test (PPVT) and verbal fluency. The sample (= 128) consisted of 43 preterms (< 1750 g) and 85 full‐terms. Structural equation modeling indicated concurrent relations of toddler information processing and language proficiency and, independent of stability in language, direct predictive links between (a) 3‐year cross‐modal ability and 13‐year PPVT and (b) 3‐year processing speed and both 13‐year measures, PPVT and verbal fluency. Thus, toddler information processing was related to growth in lexical proficiency from 3 to 13 years.  相似文献

Using data from children in South Korea (= 145, Mage = 6.08), it was determined how low‐level language and cognitive skills (vocabulary, syntactic knowledge, and working memory) and high‐level cognitive skills (comprehension monitoring and theory of mind [ToM]) are related to listening comprehension and whether listening comprehension and word reading mediate the relations of language and cognitive skills to reading comprehension. Low‐level skills predicted comprehension monitoring and ToM, which in turn predicted listening comprehension. Vocabulary and syntactic knowledge were also directly related to listening comprehension, whereas working memory was indirectly related via comprehension monitoring and ToM. Listening comprehension and word reading completely mediated the relations of language and cognitive skills to reading comprehension.  相似文献
