Problematic cost-utility analysis of interventions for behavior problems in children and adolescents.

Cost-utility analyses are slowly becoming part of randomized control trials evaluating physical and mental health treatments and (preventive) interventions in child and adolescent development. The British National Institute of Health and Care Excellence, for example, insists on the use of gains in Quality Adjusted Life Years (QALYs) to compute the "value for money" of interventions. But what counts as a gain in quality of life? For one of the most widely used instruments, the EuroQol 5 Dimensions scale (EQ-5D), QALYs are estimated by healthy individuals who provide utility scores for specific health states, assuming that the best life is a life without self-experienced problems in five domains: mobility, self-care, usual activities, pain/discomfort, and anxiety/depression. The worst imaginable outcome is defined as "a lot of problems" in each of these five domains. The impact of the individual's problems on the social network is not weighted, and important social-developmental domains (externalizing problems, social competence) are missing. Current cost-utility computations based on EQ-5D favor physical health over mental health, and they rely on adult weights for child and adolescent quality of life. Thus, a level playing field is absent, and developmental expertise is sorely missing.

Effectiveness of an attachment-based intervention for the assessment of parenting capacities in maltreating families: A randomized controlled trial.

Even though Parenting Capacity Assessments (PCAs) are essential for child protection services to support placement decisions for maltreating families, presently no evidence-based PCA protocols are available. In this randomized controlled trial, we tested the quality of an attachment-based PCA protocol based on Video-feedback Intervention to promote Positive Parenting and Sensitive Discipline (VIPP-SD). We recruited 56 parent-child dyads (Mage children = 3.48 years) in Dutch family residential clinics that conduct PCAs to support placement decisions. After pretest, families were randomized to receive the Regular Assessment Procedure (RAP) (n = 28), or an additional assessment based on VIPP-SD (n = 28). An immediate post-test and a 10-month follow-up were conducted. Multilevel models showed that therapists felt equally confident about their recommendations regarding child placement for both groups and that they equally often modified their initial placement recommendations. Moreover, children in the VIPP-SD group did not show fewer behavior problems and did not experience recurring child maltreatment less often than children in the RAP group. Thus, we found no evidence that PCAs incorporating the VIPP-SD protocol outperformed PCAs as usual. We discuss possible explanations why in the current study VIPP-SD did not seem to add to the quality of the RAP.

A pesar de que las Evaluaciones de Capacidad de Crianza (PCA) son esenciales para los servicios de protección al niño para apoyar las decisiones de dónde colocarlo por razones de familias maltratadoras, en el presente no se encuentran disponibles ningún protocolo PCA basado en la evidencia. En este ensayo controlado al azar, pusimos a prueba la calidad de un protocolo PCA basado en la afectividad para lo cual nos basamos en la Intervención de Video Informativo para promover una Crianza Positiva y Disciplina Sensible (VIPP-SD). Reclutamos 56 díadas de progenitor-niño (edad promedio de los niños = 3.48 años) en clínicas residenciales de familias holandesas que utilizan las PCA para apoyar las decisiones de dónde colocar. Después del pre-examen, las familias fueron asignadas al azar para recibir el Procedimiento de Evaluación Regular (RAP) (n = 28), o una evaluación adicional basada en VIPP-SD (n = 28). Se llevaron a cabo un examen posterior inmediato y un seguimiento a los 10 meses. Los modelos de niveles múltiples mostraron que los terapeutas se sintieron igualmente confiados acerca de sus recomendaciones con respecto a dónde colocar al niño en ambos grupos y que ellos igualmente modificaron a menudo su recomendación inicial de dónde colocarlo. Es más, los niños en el grupo VIPP-SD no mostraron menos problemas de conducta y no experimentaron maltrato infantil recurrente menos a menudo que los niños en el grupo RAP. Por tanto, no encontramos evidencia de que las PCA que incorporan el protocolo VIPP-SD tuvieran mejores resultados que las PCA en su forma usual. Discutimos posibles explicaciones de por qué en el presente estudio los VIPP-SD no parecieron agregar nada a la calidad de RAP.

Contexte: Des interventions favorables et ciblées pour les familles sont nécessaires afin d'optimiser l'ajustement parental et la relation parent-bébé conformément à un diagnostic précédant de risque neurodéveloppemental pour les bébés. Buts: Le but de cette revue systématique était de déterminer l'efficacité des interventions pour l'amélioration de l'ajustement psychologique et le bien-être pour les parents ayant un bébé ayant été diagnostiqué comme ayant ou étant à risque d'avoir un trouble neurodéveloppemental. Méthodes: La stratégie de recherche du Cochrane Review Group a été suivie avec une recherche des essais contrôlés du Registre Cochrane Central, de PubMed, CINAHL, PsycINFO, et Embase entre juillet et décembre 2017. La qualité méthodologique des articles inclus a été évaluée au moyen de l'échelle de la base de données de preuve de physiothérapie (PEDro Physiotherapy Evidence Database) par deux évaluateurs indépendants. Résultats: Douze études ont rempli les critères d'inclusion. Un petit nombre d'essais de grande qualité ont révélé une efficacité modérée à importante de la réduction chez les parents de symptômes psychologiques indésirables de trauma et de stress des parents. Des améliorations importantes dans les symptômes de dépression et d'anxiété ont émergé lors de follow up post intervention à plus long terme (6 mois-8 ans). Conclusions: On constate un soutien prometteur pour l'efficacité de certaines interventions à réduire les symptômes psychologiques de mésadaptation chez les parents avec des bébés diagnostiqués comme étant à risque d'un trouble neurodéveloppemental. D'autres ECR de qualité d'intervention psychologiques portant sur les conditions plus grandes de risque neurodéveloppemental sont nécessaires.

Annual Research Review: Umbrella synthesis of meta-analyses on child maltreatment antecedents and interventions: differential susceptibility perspective on risk and resilience.

Child maltreatment in the family context is a prevalent and pervasive phenomenon in many modern societies. The global perpetration of child abuse and neglect stands in stark contrast to its almost universal condemnation as exemplified in the United Nation's Convention on the Rights of the Child. Much work has been devoted to the task of prevention, yet a grand synthesis of the literature is missing. Focusing on two core elements of prevention, that is, antecedents for maltreatment and the effectiveness of (preventative) interventions, we performed an umbrella review of meta-analyses published between January 1, 2014, and December 17, 2018. Meta-analyses were systematically collected, assessed, and integrated following a uniform approach to allow their comparison across domains. From this analysis of thousands of studies including almost 1.5 million participants, the following risk factors were derived: parental experience of maltreatment in his or her own childhood (d = .47), low socioeconomic status of the family (d = .34), dependent and aggressive parental personality (d = .45), intimate partner violence (d = .41), and higher baseline autonomic nervous system activity (d = .24). The effect size for autonomic stress reactivity was not significant (d = -.10). The umbrella review of interventions to prevent or reduce child maltreatment showed modest intervention effectiveness (d = .23 for interventions targeting child abuse potential or families with self-reported maltreatment and d = .27 for officially reported child maltreatment cases). Despite numerous studies on child maltreatment, some large gaps in our knowledge of antecedents exist. Neurobiological antecedents should receive more research investment. Differential susceptibility theory may shed more light on questions aimed at breaking the intergenerational transmission of maltreatment and on the modest (preventive) intervention effects. In combination with family-based interaction-focused interventions, large-scale socioeconomic experiments such as cash transfer trials and experiments with vouchers to move to a lower-poverty area might be tested to prevent or reduce child maltreatment. Prevalence, antecedents, and preventive interventions of prenatal maltreatment deserve continuing scientific, clinical, and policy attention.

Physical and psychosocial development of Mapuche and nonindigenous Chilean toddlers: A modest role of ethnicity.

Mapuche represents the largest indigenous group in Chile amounting to nearly 10% of the total population. In a longitudinal cohort of 12,398 children, we analyzed the role of ethnicity in physical and psychosocial development of Mapuche and nonindigenous Chilean toddlers (age 2.5 years), taking into account sociodemographic and caregiver characteristics. As indicated by our univariate analysis, the Mapuche developmental niche was characterized by lower income, lower maternal education, poorer quality of the home environment, longer breastfeeding, and higher parental stress. Physical development showed higher body mass index. Mapuche children showed less externalizing problems. We then analyzed the incremental contribution of ethnicity in a series of hierarchical regressions with the second wave of developmental measurements (age 4.5 years) as outcome variables, showing a significant but modest incremental contribution of ethnicity to the prediction of children's development between 2.5 and 4.5 years of age. Controlling for environmental variables, Mapuche showed less externalizing and internalizing, behavior problems. Socioeconomic status, quality of the home environment, and parenting stress were stronger predictors of socioemotional development than ethnicity per se.

DIAGNOSTIC USE OF CRITTENDEN'S ATTACHMENT MEASURES IN FAMILY COURT IS NOT BEYOND A REASONABLE DOUBT.

We express serious doubt and cautioning regarding Spieker and Crittenden's (2010) claim that attachment measures associated with the dynamic-maturational model of attachment and adaptation (DMM; Crittenden, 2016) can be used for court decision-making. We demonstrate, using Crittenden's and coworkers' (e.g., Spieker & Crittenden, 2010) own data, that such measures have (a) insufficient reliability for use in individual diagnosis and (b) cannot retrodict maltreatment with sufficient sensitivity or specificity for court use. Just as atypical forms of attachment are sometimes observed among children reared adequately, typical (secure or mildly insecure) forms of attachment are sometimes observed among maltreated children and among children of caregivers struggling with psychopathology or socioeconomic adversity. The stakes are high, so it is imperative that court decisions accord with the rule of law. Certainty beyond a reasonable doubt is required, and DMM measures do not meet that requirement.

Preventing enduring behavioural problems in young children through early psychological intervention (Healthy Start, Happy Start): study protocol for a randomized controlled trial.

BACKGROUND: Behavioural problems are common in early childhood, and can result in enduring costs to the individual and society, including an increased risk of mental and physical illness, criminality, educational failure and drug and alcohol misuse. Most previous research has examined the impact of interventions targeting older children when difficulties are more established and harder to change, and have rarely included fathers. We are conducting a trial of a psychological intervention delivered to families with very young children, engaging both parents where possible. METHODS: This study is a two-arm, parallel group, researcher-blind, randomized controlled trial, to test the clinical effectiveness and cost-effectiveness of a parenting intervention, Video Feedback Intervention to Promote Positive Parenting and Sensitive Discipline (VIPP-SD) for parents of young children (12-36 months) at risk of behavioural difficulties. VIPP-SD is an evidence-based parenting intervention developed at Leiden University in the Netherlands which uses a video-feedback approach to support parents, particularly by enhancing parental sensitivity and sensitive discipline in caring for children. The trial will involve 300 families, who will be randomly allocated into either an intervention group, who will receive the video-feedback intervention (n = 150), or a control group, who will receive treatment as usual (n = 150). The trial will evaluate whether VIPP-SD, compared to treatment as usual, leads to lower levels of behavioural problems in young children who are at high risk of developing these difficulties. Assessments will be conducted at baseline, and 5 and 24 months post-randomization. The primary outcome measure is a modified version of the Preschool Parental Account of Child Symptoms (Pre-PACS), a structured clinical interview of behavioural symptoms. Secondary outcomes include caregiver-reported behavioural difficulties, parenting behaviours, parental sensitivity, parental mood and anxiety and parental relationship adjustment. An economic evaluation will also be carried out to assess the cost-effectiveness of the intervention compared to treatment as usual. DISCUSSION: If shown to be effective, the intervention could be delivered widely to parents and caregivers of young children at risk of behavioural problems as part of community based services. TRIAL REGISTRATION: ISRCTN Registry: ISRCTN58327365 . Registered 19 March 2015.

The neural correlates of dealing with social exclusion in childhood.

Observing social exclusion can be a distressing experience for children that can be followed by concerns for self-inclusion (self-concerns), as well as prosocial behavior to help others in distress (other-concerns). Indeed, behavioral studies have shown that observed social exclusion elicits prosocial compensating behavior in children, but motivations for the compensation of social exclusion are not well understood. To distinguish between self-concerns and other-concerns when observing social exclusion in childhood, participants (aged 7-10) played a four-player Prosocial Cyberball Game in which they could toss a ball to three other players. When one player was excluded by the two other players, the participant could compensate for this exclusion by tossing the ball more often to the excluded player. Using a three-sample replication (N = 18, N = 27, and N = 26) and meta-analysis design, we demonstrated consistent prosocial compensating behavior in children in response to observing social exclusion. On a neural level, we found activity in reward and salience related areas (striatum and dorsal anterior cingulate cortex (dACC)) when participants experienced inclusion, and activity in social perception related areas (orbitofrontal cortex) when participants experienced exclusion. In contrast, no condition specific neural effects were observed for prosocial compensating behavior. These findings suggest that in childhood observed social exclusion is associated with stronger neural activity for self-concern. This study aims to overcome some of the issues of replicability in developmental psychology and neuroscience by using a replication and meta-analysis design, showing consistent prosocial compensating behavior to the excluded player, and replicable neural correlates of experiencing exclusion and inclusion during middle childhood.

Splitting hair for cortisol? Associations of socio-economic status, ethnicity, hair color, gender and other child characteristics with hair cortisol and cortisone.

The aim of this study was to examine associations of SES and ethnicity with hair cortisol and cortisone and to identify potential child and family characteristics that can assist in choosing covariates and potential confounders for analyses involving hair cortisol and cortisone concentrations. Hair samples were collected in 2484 6-year-old children from the Generation R Study, a prospective cohort in Rotterdam, the Netherlands. Measurements for cortisol and cortisone were used as the outcome in regression analyses. Predictors were SES, ethnicity, hair color and child characteristics such as birthweight, gestational age at birth, BMI, disease, allergy, and medication use. Lower family income, more children to be supported by this income, higher BMI and darker hair color were associated with higher hair cortisol and cortisone levels. Boys also showed higher levels. Ethnicity (Dutch and North European descent) was related to lower levels. High amounts of sun in the month of hair collection was related to higher levels of cortisone only. More recent hair washing was related to lower levels of cortisol and cortisone. Gestational age at birth, birth weight, age, medication use, hair washing frequency, educational level of the mother, marital status of the mother, disease and allergy were not associated with cortisol or cortisone levels. Our results serve as a starting point for choosing covariates and confounders in studies of substantive predictors or outcomes. Gender, BMI, income, the number of persons in a household, ethnicity, hair color and recency of hair washing are strongly suggested to take into account.

From foundling homes to day care: a historical review of childcare in Chile.

This article discusses significant changes in childcare policy and practice in Chile. We distinguish four specific periods of childcare history: child abandonment and the creation of foundling homes in the 19th century; efforts to reduce infant mortality and the creation of the health care system in the first half of the 20th century; an increasing focus on inequality and poverty and the consequences for child development in the second half of the 20th century; and, finally, the current focus on children's social and emotional development. It is concluded that, although Chile has achieved infant mortality and malnutrition rates comparable to those of developed countries, the country bears the mark of a history of inequality and is still unable to fully guarantee the health of children from the poorest sectors of society. Recent initiatives seek to improve this situation and put a strong emphasis on the psychosocial condition of children and their families.

From foundling homes to day care: a historical review of childcare in Chile / Desde la casa de expósitos a las salas cuna: revisión histórica del cuidado infantil en Chile / Desde a casa de crianças expostas para a creche: revisão histórica da puericultura no Chile

This article discusses significant changes in childcare policy and practice in Chile. We distinguish four specific periods of childcare history: child abandonment and the creation of foundling homes in the 19th century; efforts to reduce infant mortality and the creation of the health care system in the first half of the 20th century; an increasing focus on inequality and poverty and the consequences for child development in the second half of the 20th century; and, finally, the current focus on children’s social and emotional development. It is concluded that, although Chile has achieved infant mortality and malnutrition rates comparable to those of developed countries, the country bears the mark of a history of inequality and is still unable to fully guarantee the health of children from the poorest sectors of society.

El artículo discute cambios significativos en políticas y prácticas del cuidado infantil en Chile. Se distinguen cuatro períodos históricos en los cuidados infantiles con las siguientes características: abandono infantil y la creación de la casa de expósitos en el siglo XIX; esfuerzos por disminuir la mortalidad infantil y la introducción de un sistema de salud en la primera mitad del siglo XX; un incremento en la atención de la desigualdad y la pobreza y sus consecuencias para el desarrollo infantil en la segunda mitad del siglo XX; y finalmente, una focalización en el desarrollo socioemocional de los niños. Se concluye que, aunque Chile ha alcanzado niveles de mortalidad infantil y desnutrición comparables a países desarrollados, todavía queda la marca de una historia de desigualdades que no permite garantizar completamente la salud de los niños más pobres. Recientes iniciativas tratan de mejorar esta situación y ponen un fuerte énfasis en las condiciones psicosociales de los niños y sus familias.

O artigo discute as mudanças significativas nas políticas e práticas sobre cuidado infantil, no Chile. Quatro períodos históricos foram estabelecidos, levando em consideração as seguintes características: abandono da criança e a criação de casas de crianças expostas no século XIX; esforços para reduzir a mortalidade infantil e a implementação de sistemas de cuidados de saúde na primeira metade do século XX; maior atenção à desigualdade e à pobreza, bem como as consequências que estas ações trouxeram para o desenvolvimento das crianças, na segunda metade do século XX; e, finalmente, a ênfase no desenvolvimento socioemocional das crianças. Conclui-se que, embora o Chile tenha alcançado taxas de mortalidade infantil e de desnutrição comparáveis às dos países desenvolvidos, há, ainda, indicadores históricos de desigualdade, que resultam na redução das garantias de acesso à saúde pública das crianças mais pobres. Iniciativas recentes procuram melhorar a situação e colocar a ênfase sobre as condições psicossociais de crianças e suas famílias.

Predicting ethnic minority children's vocabulary from socioeconomic status, maternal language and home reading input: different pathways for host and ethnic language.

When bilingual children enter formal reading education, host language proficiency becomes increasingly important. This study investigated the relation between socioeconomic status (SES), maternal language use, reading input, and vocabulary in a sample of 111 six-year-old children of first- and second-generation Turkish immigrant parents in the Netherlands. Mothers reported on their language use with the child, frequency of reading by both parents, and availability of children's books in the ethnic and the host language. Children's Dutch and Turkish vocabulary were tested during a home visit. SES was related to maternal language use and to host language reading input. Reading input mediated the relation between SES and host language vocabulary and between maternal language use and host language vocabulary, whereas only maternal language use was related to ethnic language vocabulary. During transition to formal reading education, one should be aware that children from low-SES families receive less host language reading input.

One doll fits all: validation of the Leiden Infant Simulator Sensitivity Assessment (LISSA).

Children vary hugely in how demanding of their caregivers they are. This creates differences in demands on parents during observation, making the comparison of sensitivity between parents difficult. It would therefore be of interest to create standard situations in which all caregivers are faced with the same level of demand. This study developed an ecologically valid but standardized setting using an infant simulator with interactive features, the Leiden Infant Simulator Sensitivity Assessment (LISSA). The infant simulator resembles a real infant in appearance and it produces crying sounds that are life-like. The simulator begins with fussing and progresses to more intense crying in case of no care or inappropriate care. It responds by being calm again if appropriate care is given. One hundred and eighty-one female participants took care of the infant simulator for two evenings and in a 30 min lab session with increasing competing demands. Sensitive parenting behavior during the lab session was coded with the Ainsworth Sensitivity Scale. Sensitivity ratings covered the whole range of the scale (1-9), and were stable across settings (free play, competing demands). Sensitivity was related to an increase of positive affect during caretaking, and insensitivity was related to intended harsh caregiving response during a computerized cry paradigm. Sensitivity was unrelated to social desirability and self-reported quality of care given to the infant simulator. We discuss the potentials of the infant simulator for research on sensitive parenting, for preventive interventions, and for clinical practices.

Socioeconomic status and parenting in ethnic minority families: testing a minority family stress model.

According to the family stress model (Conger & Donnellan, 2007), low socioeconomic status (SES) predicts less-than-optimal parenting through family stress. Minority families generally come from lower SES backgrounds than majority families, and may experience additional stressors associated with their minority status, such as acculturation stress. The primary goal of this study was to test a minority family stress model with a general family stress pathway, as well as a pathway specific to ethnic minority families. The sample consisted of 107 Turkish-Dutch mothers and their 5- to 6-year-old children, and positive parenting was observed during a 7-min problem-solving task. In addition, mothers reported their daily hassles, psychological distress, and acculturation stress. The relation between SES and positive parenting was partially mediated by both general maternal psychological stress and maternal acculturation stress. Our study contributes to the argument that stressors specific to minority status should be considered in addition to more general demographic and family stressors in understanding parenting behavior in ethnic minority families.

Is elevated risk of child maltreatment in immigrant families associated with socioeconomic status? Evidence from three sources.

In this study we tested whether children from Dutch-immigrant families are at increased risk for maltreatment, and if so, what factors could explain this risk. Three data sources from the second Netherlands Prevalence Study of Maltreatment of Youth (NPM-2010) were used to answer these questions. First, 1127 professionals from various occupational branches (sentinels) were asked to report each child (including some background information on the child and family) for whom they suspected child maltreatment during a period of three months. Second, we included the 2010 data from the Dutch Child Protective Services and third, 1759 high school students aged 11-17 years filled out a questionnaire on their experiences of maltreatment in the past year. We found that children from traditional immigrant families with a relatively long migration history in the Netherlands (Turkish, Moroccan, Surinamese, and Antillean) and from nontraditional immigrant families (African [except Morocco], Eastern European, Central Asian, and South and Central American; often refugees) were at increased risk for child maltreatment compared to native Dutch families. However, in the professionals' and CPS data this risk disappeared for the traditional immigrant families after correction for educational level of the parents and for step-parenthood. Within the group of families with low education or step-parents, the risk for child maltreatment was similar for traditional immigrant families as for native Dutch families. Nontraditional families remained at increased risk after correction for sociodemographic and family factors. In conclusion, we found that children from both traditional and nontraditional immigrant families are at increased risk for maltreatment as compared to children from native Dutch families. For the traditional immigrants this risk could partially be explained by socioeconomic status. This implies that socioeconomic factors should be taken into account when outlining policies to fight child maltreatment.

Sensitive parenting as a cross-cultural ideal: sensitivity beliefs of Dutch, Moroccan, and Turkish mothers in the Netherlands.

The primary goal of this study is to test the hypothesis that beliefs about the ideal sensitive mother are similar across Dutch, Moroccan, and Turkish mothers living in the Netherlands. A total of 75 mothers with at least one child between the ages of six months and six years described their views about the ideal sensitive mother using the Maternal Behavior Q-Sort (Pederson, Moran, & Bento, 1999 ). These views were highly similar within and across cultural and socio-economic groups. Nevertheless, family income fully mediated the relationship between ethnic background and sensitivity beliefs; income of minority mothers was lower which was in turn predictive of a lower sensitivity belief score. Our findings suggest that the main behavioral markers of sensitivity are valued by mothers from different cultural backgrounds. The role of socio-economic status in sensitivity beliefs is consistent with the Family Stress Model.

Maternal sensitivity to infants in various settings predicts harsh discipline in toddlerhood.

In a longitudinal study with 73 mothers and their second-born child, stability and main-level differences between measures of maternal sensitivity across settings and over time were examined. Furthermore, the predictability of harsh discipline by these different maternal sensitivity measures was studied. Maternal sensitivity was assessed at three and six months during bathing, free play on mother's lap and the baseline and reunion episode of the Still Face Paradigm (SFP; Tronick, Als, Adamson, Wise, & Brazelton, 1978 ). Harsh discipline was observed during three home visits in the second year of life. Results showed a single underlying factor for all maternal sensitivity settings at both time points and significant stability over time. Harsh discipline was predicted by maternal sensitivity at three months, which was fully mediated by maternal sensitivity at six months. Early failure to respond appropriately to infant signals is an important indicator of risk for future harsh parenting.

Elevated child maltreatment rates in immigrant families and the role of socioeconomic differences.

Are immigrant families at elevated risk for child maltreatment, and if so, what role do socioeconomic and family composition factors play? In a national prevalence study on child maltreatment in the Netherlands, child maltreatment cases were reported by 1,121 professionals from various occupational branches. Maltreating families were compared to a national representative family sample on immigrant status and parental educational level and family composition factors. The authors differentiated between traditional immigrant families who immigrated as labor migrants from Turkey, Morocco, Suriname, and the Antillean Islands, and nontraditional immigrant families who more recently immigrated from countries with severe economic hardships or political turmoil (refugees). Traditional immigrant and nontraditional immigrant families were both significantly overrepresented among maltreating families, but this overrepresentation disappeared for the traditional immigrants after correction for educational level of the parents. Nontraditional immigrant families, however, remained at increased risk for child maltreatment even after correction for educational level. It is proposed that interventions to prevent child maltreatment in immigrant families should focus on decreasing socioeconomic risks associated with low levels of education.

Attachment security and disorganization in maltreating and high-risk families: a series of meta-analyses.

The current meta-analytic study examined the differential impact of maltreatment and various socioeconomic risks on attachment security and disorganization. Fifty-five studies with 4,792 children were traced, yielding 59 samples with nonmaltreated high-risk children (n = 4,336) and 10 samples with maltreated children (n = 456). We tested whether proportions of secure versus insecure (avoidant, resistant, and disorganized) and organized versus disorganized attachments varied as a function of risks. Results showed that children living under high-risk conditions (including maltreatment studies) showed fewer secure (d = 0.67) and more disorganized (d = 0.77) attachments than children living in low-risk families. Large effects sizes were found for the set of maltreatment studies: maltreated children were less secure (d = 2.10) and more disorganized (d = 2.19) than other high-risk children (d = 0.48 and d = 0.48, respectively). However, children exposed to five socioeconomic risks (k = 8 studies, d = 1.20) were not significantly less likely to be disorganized than maltreated children. Overall, these meta-analyses show the destructive impact of maltreatment for attachment security as well as disorganization, but the accumulation of socioeconomic risks appears to have a similar impact on attachment disorganization.

Social development from infancy to adolescence: longitudinal and concurrent factors in an adoption sample.

In the present longitudinal study, early adopted children (N = 160) were followed from infancy to adolescence to assess the influence of previous and concurrent factors on the children's social development. This study allowed for more conclusive evidence of the influence of early and concurrent rearing experiences and temperament on adolescents' social development, independent of shared genetic factors between children and parents. Results showed that social development and temperament were stable over time and that both previous and current parental sensitivity were important in predicting social development in adolescence. Quality of the early parent-child relationship was indirectly associated with social development in adolescence through the influence on social development in middle childhood. Maternal sensitivity in middle childhood and in adolescence partly buffered the negative effects of difficult temperament on social development in adolescence. Adaptation emerged as the product of both developmental history and current circumstances.
