Bij 2-5% van de lagere schoolkinderen blijven die klachten langere tijd aanslepen en is er sprake van een duidelijk negatieve stemming en verminderd plezier en interesse. Tijdens de adolescentie neemt dat aantal jongeren met een depressie in die mate toe dat tegen de jongvolwassenheid, 12-15% van de jongeren ooit langdurige en ernstige depressieve klachten heeft gehad (Copeland, Shanahan, Costello, & Angold, 2011). Depressieve klachten gaan gepaard met hopeloze gedachten over zichzelf (niet de moeite waard zijn), de omgeving (iedereen is tegen mij, niemand houdt van mij) en de toekomst (het zal nooit goed komen met mij) (de cognitieve triade: Beck, Rush, Shaw, & Emery, 1979). Dit leidt bij vele kinderen en jongeren tot onrust en agitatie. Dat kan zich uiten in ongehoorzaam, opstandig, agressief en dwingend gedrag en wordt vaak ten onrechte bestempeld als teken van externaliserende gedragsproblemen. Anderzijds leidt dit tot verminderde energie, concentratie-problemen, eetproblemen, en slaapproblemen. Depressieve klachten kunnen leiden tot absenteïsme op school en verlies van vrienden, en verhogen de kans op zelfverwondend gedrag en suïcide (bv., Baetens, Claes, Muehlenkamp, Grietens, & Onghena, 2012; Craig, 1998). Gegeven de ernstige impact van depressieve klachten op het dagdagelijkse leven en de verdere ontwikkeling van kinderen en jongeren, is het verrassend dat volwassenen in de omgeving van het kind zoals ouders en leerkrachten vaak onwetend zijn over depressieve klachten bij kinderen (Achenbach, McConaughy, & Howell, 1987). Vaak worden jongere kinderen dan ook eerder aangemeld voor een diagnostisch onderzoek omwille van de gerelateerde klachten zoals het moeilijke gedrag of het schools en sociaal uitvallen. Naarmate kinderen ouder worden en in de adolescentie komen, stijgt de kans op suïcidepogingen (bv.,

ANS activity includes multiple indices - respiratory sinus arrhythmia (RSA) is an index of parasympathetic nervous system activation (PNS) and electrodermal activity (EDA) is an index of sympathetic nervous system activation (SNS). Children (N = 103) completed Child Attachment Interviews and read vignettes describing situations aimed to activate attachment needs (NEED; e.g., getting hurt, which can elicit need for comfort or assistance) and help-seeking (HS; when children experience need and seek comfort from attachment figures), while SNS and PNS reactivity were monitored. Attachment was not associated with children's SNS or PNS reactivity during NEED, but attachment was associated with physiological reactivity during HS: Dismissing attachment was associated with greater SNS activation (higher EDA) and preoccupied attachment with PNS deactivation (lower RSA, greater vagal withdrawal) during HS.

Research paper thumbnail of Investigating the interplay between parenting dimensions and styles, and the association with adolescent outcomes

European Child & Adolescent Psychiatry, 2019

Investigating the interplay between parenting dimensions and styles, and the association with ado... more Investigating the interplay between parenting dimensions and styles, and the association with adolescent outcomes Research has indicated that a strictly dimensional or parental style approach does not capture the full complexity of parenting. To better understand this complexity, the current study combined these two approaches by using a novel statistical technique, i.e. subspace K-means clustering. Four objectives were addressed. First, the study tried to identify meaningful groups of parents in longitudinal adolescent reports on parenting behaviour. Second, the dimensional structure of every cluster was inspected to uncover differences in parenting between and within clusters. Third, the parenting styles were compared on several adolescent characteristics. Fourth, to examine the impact of change in parenting style over time, we looked at the cluster membership over time. Longitudinal questionnaire data were collected at three annual waves, with 1,116 adolescents (mean age = 13.79 years) at Wave 1. Based on five parenting dimensions (support and proactive, punitive, psychological and harsh control), subspace K-means clustering, analysed per wave separately, identified two clusters (authoritative and authoritarian parenting) in which parenting dimensions were interrelated differently. Authoritative parenting seemed to be beneficial for adolescent development (less externalising problem behaviour and higher self-concept). Longitudinal data revealed several parenting group trajectories which showed differential relations with adolescent outcomes. Change in membership from the authoritative cluster to the authoritarian cluster was associated with a decrease in self-concept and an increase in externalising problem behaviour, whereas changes from the authoritarian cluster to the authoritative cluster was associated with an increase in self-concept and a decrease in externalising problem behaviour.

However, little is known about the convergence of mother and child’s epigenetic patterns in families. Therefore, the current study investigated epigenetic covariance in mother–child dyads’ methylation levels regarding four stress-regulation related genes (5HTT, NR3C1, FKBP5, and BDNF). Covariance was tested in a general population sample, consisting of early adolescents (Mage = 11.63, SDage = 2.3) and mothers (N = 160 dyads). Results showed that mother and offspring 5HTT and NR3C1 methylation patterns correlated. Furthermore, when averaged across genes, methylation levels strongly correlated. These findings partially supported that child and parent methylation levels covary. It might be important to consider this covariance to understand maladaptive parent–child relationships.

In the current contribution, we will discuss a large body of research suggesting that stimulating these children’s attachment development is feasible for teachers and potentially a successful strategy to ensure that these children thrive better in the classroom and socially. The current overview discusses research and theory on RAD and RAD treatment and results in the formulation of specific recommendations for the successful management of children with RAD in the classroom.
