In this article we review the literature on attachment patterns in institutionalized children and then perform a meta-analysis on data from 10 attachment studies involving 399 children in institutional settings. We computed the overall attachment distribution of secure, insecure, and disorganized rates and explored the effect of a set of moderating variables (i.e., country of institutionalization, attachment assessment procedure, age at entry, and age at assessment). To overcome bias related to the small number of studies, we conducted both classical and Bayesian meta-analysis and obtained comparable results. Distribution of children's attachment patterns was: 18% secure, 28% insecure, and 54% disorganized/cannot classify. Compared to their family-reared peers, children living in an institution were found to be at greater risk for insecure and disorganized attachment, with a similar medium effect size for both distributions (d = 0.77 and d = 0.76, respectively). The following moderating variables were associated with insecure attachment: representational assessment procedures (d = 0.63) and Eastern European countries of origin (d = 1.13). Moderators for disorganized attachment were: Eastern European countries of origin (d = 1.12), age at institution entry before the first birthday (d = 0.93), and age at assessment under three years of age (d = 0.91). Implications for child development and policies are discussed. 相似文献

Parenting programs in high-income countries have been shown to reduce the risk of child maltreatment. However, there is limited evidence of their effectiveness in low- and middle-income countries. The objective of this study was to examine the initial effects of a parenting program in reducing the risk of child maltreatment in highly-deprived and vulnerable communities in Cape Town, South Africa. Low-income parents (N = 68) with children aged three to eight years were randomly assigned to either a group-based parenting program or a wait-list control group. Observational and parent-report assessments were taken at baseline and at immediate post-test after the intervention was delivered. Primary outcomes were parent-report and observational assessments of harsh parenting, positive parenting, and child behavior problems. Secondary outcomes were parent-report assessments of parental depression, parenting stress, and social support. Results indicated moderate treatment effects for increased frequency of parent-report of positive parenting (d = 0.63) and observational assessments of parent-child play (d = 0.57). Observational assessments also found moderate negative treatment effects for less frequent positive child behavior (d = −0.56). This study is the first randomized controlled trial design to rigorously test the effectiveness of a parenting program on reducing the risk of child maltreatment in sub-Saharan Africa using both observational and self-report assessments. Results provide preliminary evidence of effectiveness of reducing the risk of child maltreatment by improving positive parenting behavior. Further development is required to strengthen program components regarding child behavior management and nonviolent discipline strategies. Future research would benefit from a larger trial with sufficient power to determine program effectiveness. 相似文献

We reviewed nine studies in which children's cortisol levels at center daycare were assessed. Our first hypothesis, concerning intraindividual differences in cortisol levels across home and daycare settings, was also tested in a meta-analysis. Our main finding was that at daycare children display higher cortisol levels compared to the home setting. Diurnal patterns revealed significant increases from morning to afternoon, but at daycare only. The combined effect size for seven pertinent studies (n = 303) was r = .18 (CI .06–.29, p = .003). We examined all papers on possible associations between cortisol levels and quality of care, and the influences of age, gender, and children's temperament. Age appeared to be the most significant moderator of this relation. It was shown that the effect of daycare attendance on cortisol excretion was especially notable in children younger than 36 months. We speculate that children in center daycare show elevated cortisol levels because of their stressful interactions in a group setting. 相似文献

This three-phase study, part of a larger study conducted by the Midwest Child Care Research Consortium (MCCRC), investigated the characteristics of child care providers in inclusive and non-inclusive center-based classrooms and family child care homes, the observed quality of care in a subset of these programs, and families’ perceptions of quality and satisfaction with child care services. A telephone survey of 2022 randomly selected Midwestern providers, 36% of whom provided inclusive services, revealed that inclusive providers rated themselves higher on most quality-related indicators. Inclusion status was related to observed quality in family childcare homes (n = 132), with non-inclusive homes higher, while trends in the opposite direction were observed in preschool center-based classrooms (n = 112) but not in infant/toddler center-based classrooms (n = 105). Six percent of the 1325 parents surveyed reported parenting a child with a disability. These parents indicated less income, and more frequent changes in child care settings than other families, and reported the quality of their children's child care as good, particularly if center-based. Improved access to inclusive child care services and enhanced training opportunities related to serving children with disabilities and inclusion, especially for family child care providers, is recommended. 相似文献

This meta-analysis (29 studies, k = 33, N = 4158) examined the longitudinal development of the relationship between performance self-efficacy and transfer before and after training. A specific focus was on training programs that afforded varying degrees of computer-supported collaborative learning (CSCL). Consistent with social cognitive theory, results suggested positive population correlation estimates between self-efficacy and transfer before (ρ = 0.31) and after (ρ = 0.39) training, and thus a small but positive increase. Three boundary conditions were estimated. First, effect sizes were higher in trainings with rather than without computer support. Second, effect sizes were higher in trainings without rather than with collaboration. Third, time lag had marginal effects. These findings are discussed in terms of their implications for theories of complex social and computer-mediated learning environments and their practical significance for scaffolding technology-enhanced learning and interaction. 相似文献

The present paper analyzes the impact of blended learning (BL) on the academic achievement of higher education students. A meta-analysis (k = 51 effect sizes) was conducted to perform a statistical synthesis of studies contrasting student performance in BL conditions with traditional classroom instruction. We include disciplines and instructors’ end-of-course evaluation method as moderating variables. The results show that BL demonstrates a small summary effect (g+ = 0.385, p < 0.001) compared to traditional teaching methods A significantly higher mean effect size was found in STEM disciplines (g+ = 0.496) compared to that of non-STEM disciplines (g+ = 0.210). Nevertheless, the weighted mean effect sizes reveal no significant differences regarding of end-of-course assessment methods, namely one-moment and multiple-component assessment. The finding confirms that BL is significantly associated with greater learning performance of STEM-disciplined students than with traditional classroom practice. Accordingly, discussion concerning the findings and implications for future research are elaborated. 相似文献

This study reports adolescent expectancy-value motivation, and its relation to fitness knowledge and psychomotor skill learning in physical education. Students (N = 854) from 12 middle schools provided data on expectancy-value motivation, fitness knowledge and psychomotor skill learning. Results from dependent t-test and MANOVA indicated that 8th grade students rated task values significantly lower than 6th grade while their expectancy beliefs did not significantly differ. Students gained sizable fitness knowledge (d = 0.58, p < 0.05) and badminton skill (d = 1.40, p < 0.05). Multiple regression analyses revealed that expectancy-value motivation did not significantly predict learning in fitness knowledge or psychomotor skills. These findings suggest that expectancy-value motivation might predict engagement and performance, but not necessarily learning achievement in physical education. 相似文献

The purpose of this study was to compare the effects of different types of questioning interventions on students' reading comprehension. Fourth-grade students (n = 246) were identified as struggling, average, or good readers and assigned randomly within school to one of three questioning interventions: two inferential conditions (Causal or General) or one literal condition (“Who, What, Where, When” or W-questioning). Teachers delivered the interventions for 20–30 min, 2–4 times per week, for 8–10 weeks. All readers made reliable pre- to posttest comprehension gains as measured by story recall (ps < .001 to .04). Differential effects for intervention were found between two subgroups of struggling comprehenders—elaborators and paraphrasers. Elaborators benefited more than paraphrasers from Causal questioning (d = .86) whereas paraphrasers benefited more than elaborators from General questioning (d = 1.46). These findings suggest that identifying subgroups is important in developing and evaluating the effectiveness of reading comprehension interventions. 相似文献

This study used a large-scale cluster randomized longitudinal experiment (N = 719; 35 schools) to investigate the effects of online mathematics mini-games on primary school students’ multiplicative reasoning ability. The experiment included four conditions: playing at school, integrated in a lesson (Eschool), playing at home without attention at school (Ehome), playing at home with debriefing at school (Ehome-school) and, in the control group, playing at school mini-games on other mathematics topics (C). The mini-games were played in Grade 2 and Grade 3 (32 mini-games in total). Using tests at the end of each grade, effects on three aspects of multiplicative reasoning ability were measured: knowledge of multiplicative number facts, skills in multiplicative operations, and insight in multiplicative number relations and properties of multiplicative operations. Through path analyses it was found that the mini-games were most effective in the Ehome-school condition, where both students’ skills and their insight were positively affected as compared to the control group (significant ds ranging from 0.22 to 0.29). In the Eschool condition, an effect was only found for insight in Grade 2 (d = 0.35), while in the Ehome condition no significant effects were found. Students’ gameplay behavior (time and effort put in the games) was in some cases, but not always, related to their learning outcomes. 相似文献

Hitting children for disciplinary purposes (i.e., spanking or corporal punishment [CP]) is a strong risk factor for child physical abuse and is highly prevalent in the U.S. Yet, little is currently known about the relevant attitudes, beliefs, or training needs of key professionals who often advise parents regarding child discipline strategies. A survey of the American Professional Society on the Abuse of Children (APSAC) membership, comprised of mental health professionals, physicians, child welfare professionals, and other professionals in the child maltreatment field, was conducted to assess attitudes, beliefs, perceived norms, training needs, and motivations to change norms regarding CP (N = 571, response rate = 51%). Most respondents agreed that spanking is a bad disciplinary technique (82%), is harmful for children (74%), and leads to negative outcomes (M = 3.0, SD = 0.6) more frequently than positive outcomes (M = 2.1, SD = 0.6; t = 20.8; p < 0.0001) for children. Professionals reported perceiving that their colleagues’ level of endorsement of CP (M = 2.4, SD = 1.0) was higher than their own (M = 1.9, SD = 1.0; t(568) = −10.7, p <0.0001) though still below the midpoint. Professionals reported high levels of preparedness to effectively advise parents on non-physical child discipline strategies, but reported perceiving lower levels of preparedness amongst their colleagues. They reported highly valuing giving such advice to parents and being very motivated to participate in activities designed to change social norms regarding CP. Most APSAC members are poised to change these norms and, in doing so, to help reduce rates of child physical abuse in the U.S. 相似文献

A major hypothesis of asset-building is that early access to savings accounts leads to continued and improved educational and economic outcomes over time. This study asks whether or not young adults (ages 18–22) in 2007, particularly among lower income households, are significantly more likely to own savings accounts and to accumulate more savings when they have access to savings accounts at banking institutions as adolescents (ages 13–17) in 2002. We investigate this question using longitudinal data (low-to-moderate income sample [LMI; N = 530]; low-income sample [LI; N = 354]) from the Panel Study of Income Dynamics and its supplements. Results from propensity score weighting and bivariate probit estimates support this hypothesis. Asset-building policies that extend early access to savings accounts may improve savings outcomes for young people from lower income households, which hopefully affords them with the economic resources needed to lead productive and satisfying lives. 相似文献

Two recently published meta-analyses (Huang, 2012, Hulleman et al., 2010) have focused on the association between achievement goals and achievement outcomes. These meta-analyses differed to some extent, e.g., regarding the identified moderators. The present meta-analysis serves to clarify those heterogeneous findings by considering more studies through 2011 and by considering more moderators. Our literature search identified 180 publications (N = 81 947). Analyses (using random effects models) revealed small but significant associations between achievement goals and achievement outcomes (r = −.12 to r = .13; all ps < .01; global performance goals: r = .01, p > .05). The results of the present moderator analyses differed from those of the previous meta-analyses. For example, in contrast to Huang (2012), we were able to find several moderators of the association between performance-approach goals and academic achievement. The results have several important implications, especially regarding the assessment of achievement goals. 相似文献

The objective of the present study was to determine whether it is possible to design a video game that could help students improve their executive function skill of shifting between competing tasks and the conditions under which playing the game would lead to improvements on cognitive tests of shifting. College students played a custom video game, Alien Game, which required the executive function skill of shifting between competing tasks. When students played for 2 h over 4 sessions they developed significantly better performance on cognitive shifting tests compared to a control group that played a different game (d = 0.62), but not when they played for 1 h over 2 sessions. Students who played Alien Game at a high level of challenge (i.e., reaching a high level in the game) developed significantly better performance on cognitive shifting tests compared to controls when they played for 2 h (Experiment 1, d = 1.44), but not when they played for 1 h (Experiment 2). Experiment 3 replicated the results of Experiment 1 using an inactive control group, showing that playing Alien Game for 2 h resulted in significant improvements in shifting skills (d = 0.78). Results show the effectiveness of playing a custom-made game that focuses on a specific executive function skill for sufficient time at an appropriate level of challenge. Results support the specific transfer of general skills theory, in which practice of a cognitive skill in a game context transferred to performance on the same skill in a non-game context. 相似文献

This study assessed the relationship between parental punishment and depression as well as quality of life in children with primary monosymptomatic nocturnal enuresis (PMNE). A consecutive sample of 65 children (7–13 years) with PMNE and 40 healthy children, selected as controls (Group III), were included in the study. The children with PMNE were further sub-classified into two groups: Group I, which included children who received parental punishment for enuresis and Group II, which comprised children who were not punished for bedwetting. Depression and health-related quality of life (HRQL) were assessed among the three groups. The number of wet nights per week was significantly increased in Group I compared with Group II (P < .001). In addition, the severity of depressive symptoms increased in Group I as compared to the other two groups (P < .001). Similarly, the psychosocial HRQL lower in Group compared to the control group (Group III) (P < .001). Prior parental discipline, including corporal punishment (B = 0.55, P = .008), as well as the frequency (B = 0.73, P < .001) and duration of punishment (B = 0.33, P = .02) were strong predictors of increased depressive symptom severity. It was also found that prior punishment (B = −0.42, P = .01) and the frequency (B = −0.62, P < .001) and duration of punishment (B = −0.34, P = .02) were strong predictors for poor psychosocial HRQL. Overall, parental punishment has a poor outcome in children with PMNE. 相似文献

This study examined whether peer support was related to psychosocial outcomes for college women serving as youth mentors in the Young Women Leaders Program (YWLP), a service-learning mentoring program. The outcomes assessed were college students’ ethnocultural empathy and their sense of competence, relatedness, and autonomy. Data included questionnaires completed by YWLP mentors (YWLP; n = 227) and college women with (CS; n = 230) and without (no CS; n = 105) alternative community service involvement. Results showed that YWLP mentors’ level of perceived peer support was associated with stronger outcomes in autonomy as compared to the CS group and in ethnocultural empathy as compared to both comparison groups. These findings extend the literature on effective support for college service-learning participants. 相似文献

ObjectiveThe sexually abused–sexual abuser hypothesis states there is a specific relationship between sexual abuse history and sexual offending, such that individuals who experience sexual abuse are significantly more likely to later engage in sexual offenses. Therefore, samples of adult sex offenders should contain a disproportionate number of individuals who have experienced sexual abuse, but not necessarily other types of abuse, compared with samples of other types of offenders.MethodsWe compared rates of sexual and other forms of abuse reported in 17 studies, involving 1,037 sex offenders and 1,762 non-sex offenders. We also examined the prevalence of different forms of abuse in 15 studies that compared adult sex offenders against adults (n = 962) and against children (n = 1,334), to determine if the sexually abused–sexual abuser association is even more specific to individuals who sexually offend against children.ResultsWe observed a higher prevalence of sexual abuse history among adult sex offenders than among non-sex offenders (Odds Ratio = 3.36, 95% confidence intervals of 2.23–4.82). The two groups did not significantly differ with regard to physical abuse history (OR = 1.50, 95% CI = 0.88–2.56). There was a significantly lower prevalence of sexual abuse history among sex offenders against adults compared to sex offenders against children (OR = 0.51, 95% CI = 0.35–0.74), whereas the opposite was found for physical abuse (OR = 1.43, 95% CI = 1.02–2.02).ConclusionThere is support for the sexually abused–sexual abuser hypothesis, in that sex offenders are more likely to have been sexually abused than non-sex offenders, but not more likely to have been physically abused. We discuss potential mechanisms for the relationship between sexual abuse history and sexual offending, including the possibility that a third factor might account for the relationship.Practice implicationsThe most obvious implications of these findings is that the prevention of sexual abuse of children, either through prevention programs directly targeting children or through treatment programs targeting individuals who are likely to sexually offend against children (e.g., known sex offenders against extra-familial boys), may eventually reduce the number of sex offenders. This implication is dependent, however, on a causal role of childhood sexual abuse, and on the effectiveness of prevention and treatment practices. 相似文献

The purpose of this study was to identify the extent to which intrinsic student factors such as cognitive learning style, learning strategies, motivation and statistics anxiety, as well as certain demographic factors, predict performance on a research design and analysis course (RDAIIA) in the Department of Psychology at the University of the Witwatersrand, South Africa, with a view to developing future interventions for improving student performance. Using a sample of eighty students, it was established that the factors most predictive of RDA performance were secondary school performance (p < 0.0001) and age (p = 0.0106). Excluding demographic factors, self-efficacy (p < 0.0001), help-seeking (p = 0.0531) and a reflective learning style (p = 0.0071) were also found to be predictive. Performance also differed between students who had completed Mathematics on the higher grade in secondary school and those who had completed standard grade (p = 0.016). These findings present both possible directions and substantial challenges for future performance-intervention strategies. 相似文献

Many children involved with the child welfare system witness parental domestic violence. The association between children's domestic violence exposure and child welfare involvement may be influenced by certain socio-cultural factors; however, minimal research has examined this relationship. The current study compares domestic violence experiences and case outcomes among Latinas who are legal immigrants (n = 39), unauthorized immigrants (n = 77), naturalized citizens (n = 30), and US-born citizen mothers (n = 383) reported for child maltreatment. This analysis used data from the second round of the National Survey of Child and Adolescent Well-being. Mothers were asked about whether they experienced domestic violence during the past year. In addition, data were collected to assess if (a) domestic violence was the primary abuse type reported and, if so, (b) the maltreatment allegation was substantiated. Results show that naturalized citizens, legal residents, and unauthorized immigrants did not differ from US-born citizens in self-reports of domestic violence; approximately 33% of mothers reported experiences of domestic violence within the past year. Yet, unauthorized immigrants were 3.76 times more likely than US-born citizens to have cases with allegations of domestic violence as the primary abuse type. Despite higher rates of alleged domestic violence, unauthorized citizens were not more likely than US-born citizens to have these cases substantiated for domestic violence (F(2.26, 153.99) = 0.709, p = .510). Findings highlight that domestic violence is not accurately accounted for in families with unauthorized immigrant mothers. We recommend child welfare workers are trained to properly assess and fulfill the needs of immigrant families, particularly as it relates to domestic violence. 相似文献

In this study, we investigated the effects of teaching critical-thinking principles on university students’ epistemological beliefs, whether these effects had any relation to the teaching approaches, and whether there was any significant interaction effect between teaching approach and students’ epistemological beliefs. One hundred and eight undergraduates were randomly assigned to three different 65-min instructional interventions, namely, General, Infusion, and Immersion approaches. Statistical analyses of the data using a Repeated Measures ANOVA showed a statistically significant higher post-assessment performance, F (1, 105) = 19.769, p = .00. The main effect related to the intervention was also significant, F (2, 105) = 3.995, p = .021, but there was no significant interaction between intervention and epistemological beliefs. Post hoc comparisons revealed that students assigned to the Infusion strategy outperformed those assigned to the General approach on epistemological change. 相似文献
