This study examined mother-child interactions and DNA methylation of the oxytocin receptor (OXTR) gene in the child, in relation with controlling-attachment behaviors at early preschool age. Maternal interactive behaviors were coded using the Emotional Availability Scales, and child attachment behaviors were assessed with the Separation-Reunion procedure and coded with the Preschool Attachment Rating Scales. DNA methylation data were captured from exon 3 of the OXTR. Results indicated that lower maternal sensitivity was associated with more controlling-caregiving behaviors, and that less maternal structuring was associated with more controlling-punitive behaviors. Hypomethylation of the OXTR gene was associated with greater maternal structuring behaviors, and with more child controlling-caregiving behaviors. The moderating role of the OXTR gene was examined in the association between interactive behaviors and child controlling behaviors, but no interaction effect was found. These results suggest that maternal interactive behaviors and OXTR methylation are independently associated with child controlling attachment. [ABSTRACT FROM AUTHOR]

Identity issues have been at the forefront in studies on determinants of youth violent radicalization. Identity uncertainty and identity fusion appear to be associated with quests for meaning, which may find some answers in extremist discourses and radical engagements. This process has been considered to be particularly important for second-generation migrants who have to negotiate multiple identities, sometimes in situations of social adversity. This paper aims to understand the relations between collective identity, social adversity (discrimination and exposure to violence), and sympathy for violent radicalization in College students in Quebec. This mixed-method study consisted of a large online survey conducted at eight colleges in Quebec. Multilevel analysis accounted for the clustered nature of data while generalized additive mixed models were used to study nonlinear relations. Results highlight the complex associations between collective identity and youth sympathy for violent radicalization. They confirm that negative public representations of minority communities may lead to more sympathy for violent radicalization. Although results suggest that strong enough identities can act as protective anchorages for youth, they also indicate that when collective identity becomes too central in personal identity this may accentuate othering processes and legitimize violence toward the out-group. These results have implications for prevention programs. They indicate that improving the public image of minority communities through mainstream media or the social media may increase youth public self-esteem and decrease their sympathy for violent radicalization. They also invite the education field to foster the development of strong plural identities.

Background: Discrepancies among studies suggest that the relation between social adversity and sympathy for violent radicalization (SVR) is multifaceted and may differ according to social context. This paper examines the role of depression, religiosity and social support in the relation between social adversity (i.e., discrimination and exposure to violence) and SVR among college students in Quebec, Canada., Methods: A total of 1894 students responded to an online questionnaire posted on the internet of eight colleges. Multilevel analyses were first conducted to account for the clustered nature of the data, followed by mediation and moderation analyses., Results: First generation migrants reported less SVR than second generation youth and non-immigrants. The mediating and/or moderating role of depression, religiosity and social support was examined through causal inference models. Depression mediated the relation between social adversity and SVR, with depression scores accounting for 47% and 25% of the total effect between discrimination and exposure to violence and SVR scores, respectively. Religiosity and social support moderated the association between social adversity and SVR., Conclusions: These results suggest that prevention programs should consider violent radicalization as a systemic issue which involves both minorities and the majority, although the specific balance between risk and protective factors may be influenced by local dynamics. They also question intervention measures targeting specifically migrants or ethno-cultural communities because of the risk of increasing profiling and stigmatization. Prevention programs should prioritize decreasing discrimination in colleges, as well as the provision of psychosocial support to depressed youth who experience social adversity., Competing Interests: Competing interestsThe authors declare that they have no competing interests., (© The Author(s). 2019.)

Our goal was to examine maternal mental health and associated stresses in a sample of high-risk immigrant mothers, and its association with child insecure attachment in the years following childbirth. Mothers and their child (Mage = 37 months) were recruited through a Health and Social Service organization in the Parc-Extension neighborhood in Montreal, Quebec. Mothers completed the Hopkins Symptoms Checklist (HSCL-25), the Multidimensional Scale of Perceived Social Support (MPSS) and a sociodemographic questionnaire that included questions on premature delivery and birth weight. Attachment behaviors were coded out of a videotaped free play sequence using the Preschool and Early School-Age Attachment Rating Scales (PARS). Analysis revealed high levels of clinical anxiety and depression, low social support and low attachment security. Significant mean differences and associations were found between anxiety, depression, social support, preterm delivery and child attachment. These results underscore the importance of screening for anxiety and depression early in the postnatal years, in order to prevent associated consequences such as child insecure attachment. Results also highlight the importance of building positive social networks, especially with immigrant populations.

Background: This article examines the association between immigration, poverty and family environment, and the emotional and behavioral problems reported by youth and their family receiving mental health (MH) services within a collaborative care model in a multiethnic neighborhood., Method: Participants in this study were 140 parent-child dyads that are part of an ongoing longitudinal project looking at the association between individual, familial, social and organizational factors, and outcomes of youth receiving MH services in local health and social service organizations in the Montreal area. Measures included in this study were collected at the initial phase of the longitudinal project (Time 0). Parents completed a sociodemographic questionnaire and the Family Environment Scale (FES), and both parents and children completed the Strength and Difficulties questionnaire (SDQ)., Results: Results suggest that the family environment, especially family conflicts, has a significant role in the MH problems of children seeking help in collaborative MH services. In this specific population, results also show a trend, but not a statistically significant association, between poverty or immigration and emotional and behavioral problems. They suggest as well that boys show more MH problems, although this could be a contamination effect (parents' perspective)., Conclusions: The results support the importance of interventions that not only target the child symptomatology but also address family dynamics, especially conflicts. Collaborative care models may be particularly well suited to allow for a coherent consideration of family environmental factors in youth mental health and to support primary care settings in addressing these issues.

This pilot study examined psychological, social and cultural risk factors for child insecure attachment in a sample of South Asian immigrant families experiencing high migration stress in Montreal, Canada. Thirty-three participants were recruited through a local Health and Social Service organization. Maternal anxiety and depression, social support, and national and religious sense of belonging were assessed. Child attachment behaviors were coded from a 15 min free play period. Results indicated that maternal depressive symptoms were related to lower child attachment security scores. Lower support from friends was related to greater child ambivalent attachment behaviors. A higher sense of belonging to the country of origin was related to greater child disorganized attachment behaviors. These findings suggest that migration stresses, which include maternal depression, lack of social support and the sense of belonging, are associated with child attachment, and these variables should be considered in the design of appropriate interventions.

Background: Efforts to understand the developmental pathways for disorganized attachment reflect the importance of disorganized attachment on the prediction of future psychopathology. The inconsistent findings on the prediction of disorganized attachment from the dopamine D4 receptor (DRD4) gene, birth weight, and maternal depression as well as the evidence supporting the contribution of early maternal care, suggest the importance of exploring a gene by environment model., Methods: Our sample is from the Maternal Adversity, Vulnerability, and Neurodevelopment project; consisting of 655 mother-child dyads. Birth weight was cross-referenced with normative data to calculate birth weight percentile. Infant DRD4 genotype was obtained with buccal swabs and categorized according to the presence of the 7-repeat allele. Maternal depression was assessed with the Center for Epidemiologic Studies Depression Scale at the prenatal, 6-, 12-, and 24-month assessments. Maternal attention was measured at 6-months using a videotaped session of a 20-min non-feeding interaction. Attachment was assessed at 36-months using the Strange Situation Procedure., Results: The presence of the DRD4 7-repeat allele was associated with less disorganized attachment, β=-1.11, OR=0.33, p=0.0008. Maternal looking away frequency showed significant interactions with maternal depression at the prenatal assessment, β=0.003, OR=1.003, p=0.023, and at 24 months, β=0.004, OR=1.004, p=0.021, as at both time points, women suffering from depression and with frequent looking away behavior had an increased probability of disorganized attachment in their child, while those with less looking away behavior had a decreased probability of disorganized attachment in their child at 36 months., Conclusions: Our models support the contribution of biological and multiple environmental factors in the complex prediction of disorganized attachment at 36 months., (Copyright © 2017 Elsevier Inc.

Despite empirical evidence on the numerous consequences associated with high migration stress and mental health problems during pregnancy, a psychosocial stress assessment is rarely done, leaving it largely unaddressed. This case illustration sheds light on the common multiple risk factors related to migration stress that have to be taken into consideration when addressing perinatal mental health, and highlights the importance of obstetric appointments as a unique opportunity to assess psychosocial stress and mobilize interdisciplinary interventions.

Disorganized attachment is an important early risk factor for socioemotional problems throughout childhood and into adulthood. Prevailing models of the etiology of disorganized attachment emphasize the role of highly dysfunctional parenting, to the exclusion of complex models examining the interplay of child and parental factors. Decades of research have established that extreme child birth weight may have long-term effects on developmental processes. These effects are typically negative, but this is not always the case. Recent studies have also identified the dopamine D4 receptor (DRD4) as a moderator of childrearing effects on the development of disorganized attachment. However, there are inconsistent findings concerning which variant of the polymorphism (seven-repeat long-form allele or non-seven-repeat short-form allele) is most likely to interact with caregiving in predicting disorganized versus organized attachment. In this study, we examined possible two- and three-way interactions and child DRD4 polymorphisms and birth weight and maternal caregiving at age 6 months in longitudinally predicting attachment disorganization at 36 months. Our sample is from the Maternal Adversity, Vulnerability and Neurodevelopment project, a sample of 650 mother-child dyads. Birth weight was cross-referenced with normative data to calculate birth weight percentile. Infant DRD4 was obtained with buccal swabs and categorized according to the presence of the putative allele seven repeat. Macroanalytic and microanalytic measures of maternal behavior were extracted from a videotaped session of 20 min of nonfeeding interaction followed by a 10-min divided attention maternal task at 6 months. Attachment was assessed at 36 months using the Strange Situation procedure, and categorized into disorganized attachment and others. The results indicated that a main effect for DRD4 and a two-way interaction of birth weight and 6-month maternal attention (frequency of maternal looking away behavior) and sensitivity predicted disorganized attachment in robust logistic regression models adjusted for social demographic covariates. Specifically, children in the midrange of birth weight were more likely to develop a disorganized attachment when exposed to less attentive maternal care. However, the association reversed with extreme birth weight (low and high). The DRD4 seven-repeat allele was associated with less disorganized attachment (protective), while non-seven-repeat children were more likely to be classified as disorganized attachment. The implications for understanding inconsistencies in the literature about which DRD4 genotype is the risk direction are also considered. Suggestions for intervention with families with infants at different levels of biological risk and caregiving risk are also discussed.

Background: Preterm children have been reported to be at higher risk to develop attachment insecurity., Aims: The present study aimed to investigate potential differences in attachment security between newborns who were sent to Neonatal Intensive Care Unit (NICU) and those who were not, in a population of full-term children., Study Design: Participants (162 mother-child dyads) were part of a longitudinal study (MAVAN). Twenty-three of these children received special care at birth (NICU group). Attachment security was assessed at 36 months with the Strange Situation Procedure. Socio-economic status (SES), birth weight, maternal mood, maternal sensitivity, mental/psychomotor developmental indexes, Apgar scores, presence of complications during delivery and infant general health were assessed., Results: In the No-NICU group, 55.4% of children were securely attached, 24.5% were insecure and 20.1% were disorganized. However, in the NICU group, 43.5% of children were securely attached, 8.7% were insecure and 47.8% were disorganized (χ(2)=9.0; p=.01). The only differences between the 2 groups were a lower Apgar, more respiratory infections and more visits to walk-in clinic/hospital (p's<.05) and a trend for lower SES and more ear infections in the NICU group. Logistic regressions revealed an odds ratio of 6.1 (p=.003) of developing a disorganized attachment after a stay in NICU, when controlling for these confounding variables., Conclusion: Newborns who were admitted to NICU have an odds ratio of about 6 to develop a disorganized attachment at 36 months. These preliminary results support the importance of supportive parental proximity and contact with the infant in the NICU and possible after-care., (Copyright © 2015.

In this article, we will evaluate the evidence concerning links between attachment and behavior problems in the middle childhood period. We will first provide a general introduction to the question of attachment and maladaptation in the middle childhood period, and then examine the recent empirical evidence with respect to both externalizing and internalizing profiles. We will conclude with a discussion of new directions in research on this issue including the search for possible mediators and moderators of attachment/behavior problem associations., (© 2015 Wiley Periodicals, Inc.)

Background: The current paper aimed to explore the effects of birth weight and the 7-repeat allele in Exon III of the dopamine D4 receptor (DRD4) gene on the development of disorganized attachment, a potential endophenotype of depression. Infants born with low birth weight have been shown to be at higher risk for later neurological impairments, psychological disorders or behavioural problems. The DRD4 gene is critical for the cognitive and emotional processes that are sub-served by neural circuits in the prefrontal cortex. This paper examined the main effect of birth weight and DRD4 on the development of disorganized attachment., Methods: Data was used from the Maternal Adversity, Vulnerability and Neurodevelopment (MAVAN) project. The sample consisted of 251 mother-child dyads with complete data. Attachment style was assessed using the modified separation-reunion procedure., Results: There was no main effect for birth weight on disorganized attachment, (b = -0.001, p = 0.998). There was, however, a main effect for the DRD4 7-repeat polymorphism on disorganized attachment (b = -1.120, p = 0.004)., Limitations: Compared to studies of similar design, the sample size in this study was relatively small. Additionally, a significant number of subjects did not have complete data., Conclusions: Children without the DRD4 7-repeat allele were more likely to have disorganized attachment than children with the DRD4 7-repeat allele. This indicates that the 7-repeate allele of the DRD4 gene may actually serve as a protective factor against disorganized attachment.

The development of sleep-wake regulation in infants depends upon brain maturation as well as various environmental factors. The aim of the present study was to evaluate sleep duration and quality as a function of child attachment to the mother. One hundred and thirty-four mother-child dyads enrolled in the Maternal Adversity, Vulnerability and Neurodevelopment (MAVAN) project were included in this study. Attachment was assessed with the Strange Situation procedure at 36 months and maternal sleep reports were collected at 6, 12, 24 and 36 months. Differences in sleep characteristics were assessed with mixed models with one factor (attachment group) and one repeated measure (age). Children classified as disorganized had a significantly lower duration of nocturnal sleep, went to bed later, signaled more awakenings, had shorter periods of uninterrupted sleep (only at 12 months) and had shorter periods of time in bed (only at 6 months) than children classified as secure and/or ambivalent (p < 0.05). This is the first study to show that children with insecure disorganized attachment present a distinct sleep pattern in comparison with those with secure or ambivalent attachment between 6 and 36 months of age. Sleep disturbances could exacerbate difficulties in these families that are already considered vulnerable.

The aim of this study was to investigate longitudinal associations between attachment at early school age and the development of externalizing symptoms in adolescence. The mediating roles of maternal helplessness and role reversal were also examined. Attachment classifications of 136 children (63 boys and 73 girls) and quality of mother-child interactions (role reversal) were observed at ages 5-6 using the separation-reunion procedure (Main & Cassidy, 1988). At age 13, externalizing problems reported by both the adolescent and the mother (Youth Self-Report; Achenbach, 1991), and caregiving helplessness reported by the mother (Caregiving Helplessness Questionnaire; George, Coulson, & Magana, 1997) were evaluated. Results indicated that children with disorganized attachment to their caregivers evidenced the most maladaptive patterns compared with children with secure attachment, displaying high externalizing symptoms and having mothers reporting more helplessness. Significant differences found among the disorganization subtypes indicated that the controlling-punitive subgroup had more maladaptive patterns across variables than did the behaviorally disorganized and controlling-caregiving subgroups. These findings support the idea that early attachment, mother-child interaction quality, and caregiving helplessness should be central themes in prevention and intervention programs with mother-child dyads.

This article describes a video-feedback intervention program with maltreating parents and their children aged 1 to 5 years using a case-study approach. The 8-week program is of interest to researchers and clinicians because it is the first short-term attachment-based intervention program to demonstrate efficacy in enhancing parental sensitivity, improving child attachment security, and reducing disorganized attachment for children and parents who have been reported for child abuse and/or neglect. We have previously described the theoretical and empirical basis of the intervention program and evidence for its efficacy. Details of program implementation and a case study are currently presented.

This study examined the longitudinal association between preschool attachment patterns, the development of anxiety and depression at preadolescence and the mediational role of self-esteem. Child-mother attachment classifications of 68 children (33 girls) were assessed between 3-4 years of age (M = 3.7 years, SD = 4.4 months) using the Separation-Reunion Procedure. At age 11-12 (M = 11.7 years, SD = 4.3 months), anxiety and depressive symptoms (Dominic Interactive Questionnaire), and self-esteem (Self-Perception Profile for Children) were also evaluated. Preadolescents who had shown disorganized attachment at preschool age scored higher on both anxiety and depression and lower on self-esteem than those who had shown secure and insecure-organized attachment strategies. Self-esteem was a partial mediator of the association between preschool disorganization and symptoms of preadolescent depression, but the model was not supported for anxiety. These findings support the idea that early attachment and self-esteem should be central themes in prevention programs with young children.
