What works in school-based programs for child abuse prevention? The perspectives of young child abuse survivors

Previous research has shown that youth consider school-based child abuse prevention programs as one of the most important strategies for preventing child abuse and neglect. This study asked young child abuse survivors how school-based child abuse prevention programs should be shaped and what program components they perceive as essential. Semi-structured interviews were conducted with 13 Dutch young adults that were a victim of child abuse or neglect. A literature review that resulted in 12 potential program components was used to guide the interviews. All young adults agreed that school-based child abuse prevention programs are important and have positive effects on children’s awareness of child abuse. Teaching children that they are never to blame for child abuse occurrences was considered one of the most important components of school-based programs, next to teaching children how to escape from threatening situations and to find help, increasing children’s social–emotional skills, promoting child abuse related knowledge, recognizing risky situations, and increasing children’s self-esteem. Further, the participants found it important to provide children with aftercare when a school program has ended. Overall, young child abuse survivors have a strong view on what should be addressed in school-based child abuse prevention programs to effectively prevent child abuse.</p

Addressing Dependency in Meta-Analysis: A Companion to Assink and Wibbelink (2016)

This research note elaborates on addressing dependency in effect size data and serves as a companion to our tutorial on fitting three-level meta-analytic models in R (Assink and Wibbelink, 2016). We provide a description of effect size and standard error dependency, explain how both the multilevel and multivariate meta-analytic models handle these types of dependency, and discuss the role of alternative methods in addressing dependency in effect size data, including approximating a variance-covariance matrix and applying a cluster-robust inference method. These alternative methods are illustrated with example R code that builds upon the effect size dataset that we presented and analyzed in our tutorial. We conclude that more simulation studies are needed to provide clearer guidelines for modeling dependency in effect size data and urge statisticians to make the available technical literature further accessible to applied researchers

A Dose of Nature:Two three-level meta-analyses of the beneficial effects of exposure to nature on children's self-regulation

There is growing evidence that exposure to nature, as opposed to a built environment, is associated with better health. Specifically in children, more exposure to nature seems to be associated with better cognitive, affective, and behavioral self-regulation. Because studies are scattered over different scientific disciplines, it is difficult to create a coherent overview of empirical findings. We therefore conducted two meta-analyses on the effect of exposure to nature on self-regulation of schoolchildren (Mage = 7.84 years; SD = 2.46). Our 3-level meta-analyses showed small, but significant positive overall associations of nature with self-regulation in both correlational (15 studies, r = .10; p < .001) and (quasi-) experimental (16 studies, d = .15; p < .01) studies. Moderation analyses revealed no differential associations based on most sample or study characteristics. However, in correlational studies the type of instrument used to measure exposure to nature (index score of nature vs. parent-reported exposure) significantly moderated the association between nature and self-regulation. Stronger associations were found when exposure to nature was assessed via parent-reports than via an index such as by a normalized difference vegetation index (NDVI). Our findings suggest that nature may be a promising tool in stimulating children's self-regulation, and possibly preventing child psychopathology. However, our overview also shows that we are in need of more rigorous experimental studies, using theoretically based conceptualizations of nature, and validated measures of nature and its putative outcomes

Ramping Up Detention of Young Serious Offenders: A Safer Future?

When youth commit serious violent or sexual offenses, this often generates a call for more severe punishments and longer detention sentences. An important question is whether (long) detention sentences are effective in decreasing recidivism among serious young offenders. To estimate recidivism rates in serious young offenders and elucidate the link between sentencing (in terms of custodial vs. non-custodial and length of imprisonment) and recidivism, three multilevel meta-analyses were conducted. With a systematic literature search, 27 studies and four datasets were traced, involving N = 2,308 participants, yielding 90 effect sizes for overall recidivism, 24 for specifically violent recidivism, and 23 for the association between length of imprisonment and recidivism. The average weighted overall recidivism rate was 44.47% (95% confidence interval [CI]: 37.59–51.46%) over an average period of 8.68 years. The rate of violent recidivism was estimated at 30.49% (95% CI: 20.92–40.52%), over an average period of 11.45 years. Recidivism rates were higher when recidivism was defined as an arrest for any new offense rather than for a specific offense and in studies conducted in the United States versus European studies. Violent recidivism rates were higher in studies with longer follow-up periods. Based on the limited available studies, no difference in recidivism rates following custodial and non-custodial sentences were found, nor an association between length of imprisonment and recidivism. To increase rehabilitation chances for youth offenders, further research is warranted to better understand the impact of sentencing and to ascertain what is needed to make custodial and non-custodial sentences more effective

Children’s domain-specific self-evaluations and global self-worth:: A preregistered cross-cultural meta-analysis

Which domain-specific self-evaluations are most central to children’s global self-worth? And does this differ between countries with different levels of collectivism–individualism? We conducted a preregistered cross-cultural meta-analysis to address these questions. We included 141 independent samples (21 countries/regions, 584 cross-sectional effect sizes), totaling 33,120 participants in middle to late childhood, a critical age for self-worth development. Overall, global self-worth was most strongly correlated with self-evaluations in the domain of physical appearance (r = .64), followed by behavioral conduct, peer relations, academic competence, athletic competence, and parent relations (rs = .39 to .54). Global self-worth was equally strongly correlated with agentic and communal self-evaluations (r = .51 and .52, respectively). The strength of these associations did not vary significantly by country-level collectivism–individualism. These findings reveal the robust correlates of self-worth across cultures and raise important new questions about when and how culture shapes the development of children’s global self-worth

Risk factors for juvenile cybercrime: A meta-analytic review

So far, most meta-analyses and reviews on juvenile crime risk factors focused on risk factors for traditional crimes. It is unknown, though, whether these risk factors are also relevant for the explanation of cybercrime perpetration. This meta-analytic review aimed to identify risk factors for cyberstalking, hacking, and sexting perpetrated by juveniles. A literature search yielded 48 articles (24 for cyberstalking, 15 for sexting, and 10 for hacking) that produced 903 effect sizes (306 for cyberstalking, 61 for sexting, and 536 for hacking). The results showed similarities, but also differences in risk factors for the three types of cybercrime. Overall, peer factors were found to be important for all three types (deviant peers for cyberstalking and hacking and peer pressure for sexting). Besides, for cyberstalking, previous online and offline perpetration and victimization were significant risk factors. Other small but significant effects for multiple cybercrime types were found for dark personality traits (for cyberstalking and sexting) and high computer preoccupation (for cyberstalking and hacking). Implications for (preventive) intervention are discussed, as well as the need for future research

Long-term collateral effects of parent programs on child maltreatment proxies:Can administrative data provide useful insights?

Collecting child maltreatment data from participants is expensive and time-consuming, and often suffers from substantial attrition rates. Administrative population data may prove fruitful to overcome these barriers. The aim of this study was twofold: (1) to illustrate how administrative data may be used in evaluating long-term intervention effects; and (2) to examine collateral effects of three preventive early childhood interventions offered to families in the Netherlands (Supportive Parenting, VoorZorg, and Incredible Years). Using population data, four proxies of child maltreatment were assessed to examine collateral intervention effects: incidences of child protection orders, placements of children in residential care, crime victimization of children or their parents, and parental registrations as a crime suspect. The results revealed no significant differences between experimental and control conditions on any of these proxies, with very small effect sizes (ranging from Cramer's V = 0.01 to Cramer's V = 0.10). We conclude that the results do not provide support for collateral effects, but that studying other outcomes may provide this support. We further discuss that small sample sizes and low prevalences challenge studies using administrative data. Notwithstanding these limitations, we conclude that administrative data can strengthen the evidence base for collateral and direct intervention effects.</p

Components associated with the effect of home visiting programs on child maltreatment: A meta-analytic review

Background: Home visiting programs are widely endorsed for preventing child maltreatment. Yet, knowledge is lacking on what and how individual program components are related to the effectiveness of these programs. Objective: The aim of this meta-analysis was to increase this knowledge by summarizing findings on effects of home visiting programs on child maltreatment and by examining potential moderators of this effect, including a range of program components and delivery techniques. Methods: A literature search yielded 77 studies (N=48,761) examining the effectiveness of home visiting programs, producing 174 effect sizes. In total, 35 different program components and delivery techniques were coded. Results: A small but significant overall effect was found (d=0.135, 95 % CI (0.084, 0.187), p<0.001). Programs that focused on improving parental expectations of the child or parenthood in general (d = 0.308 for programs with this component versus d = 0.112 for programs without this component), programs targeting parental responsiveness or sensitivity to a child's needs (d = 0.238 versus d = 0.064), and programs using video-based feedback (d = 0.397 versus d = 0.124) yielded relatively larger effects. Providing practical and instrumental assistance was ne

Infrasound as a cue for seabird navigation

Seabirds are amongst the most mobile of all animal species and spend large amounts of their lives at sea. They cross vast areas of ocean that appear superficially featureless, and our understanding of the mechanisms that they use for navigation remains incomplete, especially in terms of available cues. In particular, several large-scale navigational tasks, such as homing across thousands of kilometers to breeding sites, are not fully explained by visual, olfactory or magnetic stimuli. Low-frequency inaudible sound, i.e., infrasound, is ubiquitous in the marine environment. The spatio-temporal consistency of some components of the infrasonic wavefield, and the sensitivity of certain bird species to infrasonic stimuli, suggests that infrasound may provide additional cues for seabirds to navigate, but this remains untested. Here, we propose a framework to explore the importance of infrasound for navigation. We present key concepts regarding the physics of infrasound and review the physiological mechanisms through which infrasound may be detected and used. Next, we propose three hypotheses detailing how seabirds could use information provided by different infrasound sources for navigation as an acoustic beacon, landmark, or gradient. Finally, we reflect on strengths and limitations of our proposed hypotheses, and discuss several directions for future work. In particular, we suggest that hypotheses may be best tested by combining conceptual models of navigation with empirical data on seabird movements and in-situ infrasound measurements
