Sibling relationships and school entry psychosocial functioning: Dual risk or differential susceptibility?

The aim of the present study was to test whether relations between temperament, sibling relationship quality, and problem behavior and social competence of children at school entry are in line with either of two competing models, dual risk and differential susceptibility. Our sample consisted of 977 Dutch mothers (Mean age 35.7 years) reporting about a target child at school entry. Regarding target children, mean age was 4.7 years, 48.1% were boys and 52.1% were older than their sibling. Mean age difference between siblings was 2.7 years. Using a cross-sectional design, mothers filled out online questionnaires concerning sibling relationship quality, temperament, problem behavior, and social competence of the target child. Path analysis was used to examine whether temperament moderated the link between sibling relationship quality and child psychosocial functioning. In line with differential susceptibility, results from moderation analyses indicate that among children low in effortful control (EC), sibling conflict was more strongly positively associated with internalizing and externalizing problems than among children high in EC, but sibling warmth also was more strongly positively related to social competence in children low in EC than in children high in EC. However, follow-up Region of Significance analyses shows that our findings are only consistent with weak differential susceptibility. No significant moderation effects were found for surgency or negative affect. Our findings suggest that low effortful control is a susceptibility marker concerning the link between sibling relationship quality and child functioning. Limitations, implications, and future directions are discussed. (PsycInfo Database Record (c) 2022 APA, all rights reserved).

Linking emotional reactivity "for better and for worse" to differential susceptibility to parenting among kindergartners.

This study used a combination of microlevel observation data and longitudinal questionnaire data to study the relationship between differential reactivity and differential susceptibility, guided by three questions: (a) Does a subset of children exist that is both more likely to respond with increasingly negative emotions to increasingly negative emotions of mothers and with increasingly positive emotions to increasingly positive emotions of mothers ("emotional reactivity")? (b) Is emotional reactivity associated with temperament markers and rearing environment? (c) Are children who show high emotional reactivity "for better and for worse" also more susceptible to parenting predicting child behavior across a year? A total of 144 Dutch children (45.3% girls) aged four to six participated. Latent profile analyses revealed a group of average reactive children (87%) and a group that was emotionally reactive "for better and for worse" (13%). Highly reactive children scored higher on surgency and received lower levels of negative parenting. Finally, associations of negative and positive parenting with externalizing and prosocial behavior were similar (and nonsignificant) for highly reactive children and average reactive children. The findings suggest that children who are emotionally reactive "for better and for worse" within parent-child interactions are not necessarily more susceptible to parenting on a developmental time scale.

Sensory processing sensitivity as a marker of differential susceptibility to parenting.

In this longitudinal multiinformant study negative emotionality and sensory processing sensitivity were compared as susceptibility markers among kindergartners. Participating children (N = 264, 52.9% boys) were Dutch kindergartners (Mage = 4.77, SD = 0.60), followed across three waves, spaced seven months apart. Results show that associations between parenting and child behavior did not depend on children's negative emotionality. Sensory processing sensitivity, however, interacted with both (changes in) negative and (changes in) positive parenting in predicting externalizing, but not prosocial, behavior. Depending on the interaction, vantage sensitivity and differential susceptibility models were supported. The findings suggest that sensory processing sensitivity may be a more proximal correlate of individual differences in susceptibility, compared with negative emotionality. (PsycINFO Database Record

Perception is key? Does perceptual sensitivity and parenting behavior predict children's reactivity to others' emotions?

When interacting with other people, both children's biological predispositions and past experiences play a role in how they will process and respond to social-emotional cues. Children may partly differ in their reactions to such cues because they differ in the threshold for perceiving such cues in general. Theoretically, perceptual sensitivity (i.e., the amount of detection of slight, low-intensity stimuli from the external environment independent of visual and auditory ability) might, therefore, provide us with specific information on individual differences in susceptibility to the environment. However, the temperament trait of perceptual sensitivity is highly understudied. In an experiment, we tested whether school-aged children's (N=521, 52.5% boys, Mage=9.72years, SD=1.51) motor (facial electromyography) and affective (self-report) reactivities to dynamic facial expressions and vocalizations is predicted by their (parent-reported) perceptual sensitivity. Our results indicate that children's perceptual sensitivity predicts their motor reactivity to both happy and angry expressions and vocalizations. In addition, perceptual sensitivity interacted with positive (but not negative) parenting behavior in predicting children's motor reactivity to these emotions. Our findings suggest that perceptual sensitivity might indeed provide us with information on individual differences in reactivity to social-emotional cues, both alone and in interaction with parenting behavior. Because perceptual sensitivity focuses specifically on whether children perceive cues from their environment, and not on whether these cues cause arousal and/or whether children are able to regulate this arousal, it should be considered that perceptual sensitivity lies at the root of such individual differences.

Children's differential susceptibility to parenting: An experimental test of "for better and for worse".

Differential susceptibility theory proposes that a subset of individuals exist who display enhanced susceptibility to both negative (risk-promoting) and positive (development-enhancing) environments. This experiment represents the first attempt to directly test this assumption by exposing children in the experimental group to both negative and positive feedback using puppet role-plays. It thereby serves as an empirical test as well as a methodological primer for testing differential susceptibility. Dutch children (N=190, 45.3% girls) between the ages of 4 and 6years participated. We examined whether negative and positive feedback would differentially affect changes in positive and negative affect, in prosocial and antisocial intentions and behavior, depending on children's negative emotionality. Results show that on hearing negative feedback, children in the experimental group increased in negative affect and decreased in positive affect more strongly than children in the control group. On hearing positive feedback, children in the experimental group tended to increase in positive affect and decrease in prosocial behavior. However, changes in response to negative or positive feedback did not depend on children's negative emotionality. Moreover, using reliable change scores, we found support for a subset of "vulnerable" children but not for a subset of "susceptible" children. The findings offer suggestions to guide future differential susceptibility experiments.

Differences in sensitivity to parenting depending on child temperament: A meta-analysis.

Several models of individual differences in environmental sensitivity postulate increased sensitivity of some individuals to either stressful (diathesis-stress), supportive (vantage sensitivity), or both environments (differential susceptibility). In this meta-analysis we examine whether children vary in sensitivity to parenting depending on their temperament, and if so, which model can best be used to describe this sensitivity pattern. We tested whether associations between negative parenting and negative or positive child adjustment as well as between positive parenting and positive or negative child adjustment would be stronger among children higher on putative sensitivity markers (difficult temperament, negative emotionality, surgency, and effortful control). Longitudinal studies with children up to 18 years (k = 105 samples from 84 studies, Nmean = 6,153) that reported on a parenting-by-temperament interaction predicting child adjustment were included. We found 235 independent effect sizes for associations between parenting and child adjustment. Results showed that children with a more difficult temperament (compared with those with a more easy temperament) were more vulnerable to negative parenting, but also profited more from positive parenting, supporting the differential susceptibility model. Differences in susceptibility were expressed in externalizing and internalizing problems and in social and cognitive competence. Support for differential susceptibility for negative emotionality was, however, only present when this trait was assessed during infancy. Surgency and effortful control did not consistently moderate associations between parenting and child adjustment, providing little support for differential susceptibility, diathesis-stress, or vantage sensitivity models. Finally, parenting-by-temperament interactions were more pronounced when parenting was assessed using observations compared to questionnaires. (PsycINFO Database Record

5-HTTLPR Expression Outside the Skin: An Experimental Test of the Emotional Reactivity Hypothesis in Children.

BACKGROUND: There is increasing evidence that variation in the promoter region of the serotonin transporter gene SLC6A4 (i.e., the 5-HTTLPR polymorphism) moderates the impact of environmental stressors on child psychopathology. Emotional reactivity -the intensity of an individual's response to other's emotions- has been put forward as a possible mechanism underlying these gene-by-environment interactions (i.e., G×E). Compared to children homozygous for the L-allele (LL-genotypes), children carrying an S-allele (SS/SL-genotypes), specifically when they have been frequently exposed to negative emotions in the family environment, might be more emotionally reactive and therefore more susceptible to affective environmental stressors. However, the association between 5-HTTLPR and emotional reactivity in children has not yet been empirically tested. Therefore, the goal of this study was to test this association in a large-scale experiment. METHODS: Children (N = 521, 52.5% boys, Mage = 9.72 years) were genotyped and randomly assigned to happy, angry or neutral dynamic facial expressions and vocalizations. Motor and affective emotional reactivity were assessed through children's self-reported negative and positive affect (n = 460) and facial electromyography activity (i.e., fEMG: the zygomaticus or "smile" muscle and the corrugator or "frown" muscle, n = 403). Parents reported on their negative and positive parenting behaviors. RESULTS: Children mimicked and experienced the emotion they were exposed to. However, neither motor reactivity nor affective reactivity to these emotions depended on children's 5-HTTLPR genotype: SS/SL-genotypes did not manifest any stronger response to emotional stimuli than LL-genotypes. This finding remained the same when taking the broader family environment into account, controlling for kinship, age, gender and genetic ancestry, and when including a tri-allelic factor. CONCLUSIONS: We found no evidence for an association between the 5-HTTLPR polymorphism and children's emotional reactivity. This finding is important, in discounting one potential underlying endophenotype of G×E between the 5-HTTLPR and affective environmental stressors.

Personality traits as potential susceptibility markers: differential susceptibility to support among parents.

In this study, we examined whether parents are differentially susceptible to support from their spouse and adolescent child depending on their personality traits, and whether differences in susceptibility to support among parents, in turn, are linked to the quality of support parents give to their children. Participants in this three-wave longitudinal study were 288 two-parent Dutch families with an adolescent child. Fathers were on average 43.9 years old (SD = 3.7 years), mothers were 41.7 years old (SD = 3.3 years), and adolescents (50% girls) were 14.5 years old (SD = 0.8 years). We found that the association between support from children toward their parents and subsequent support from parents toward their children was more pronounced for parents high on Openness, for better and for worse. Extraversion, Agreeableness, Conscientiousness, and Emotional Stability did not emerge as markers of differences in susceptibility. Also, parents did not differ in their susceptibility to support from their spouse, nor were differences in susceptibility found a year later when using data from a third wave. We found very modest support for differential susceptibility, only for Openness, and depending on the source of perceived support and on the timing of measurement.

My Child Redeems My Broken Dreams: On Parents Transferring Their Unfulfilled Ambitions onto Their Child.

From the early days of psychology, theorists have observed that parents sometimes transfer their own unfulfilled ambitions onto their child. We propose that parents are especially inclined to do so when they see their child as part of themselves, more so than as a separate individual. When parents see their child as part of themselves, their child's achievements may easily come to function as a surrogate for parents' own unfulfilled ambitions. In the present experiment, 73 parents (89% women, M age = 43 years) were randomly assigned to reflect on either their own or others' unfulfilled ambitions. Results showed that, when faced with their own unfulfilled ambitions, parents who see their child as part of themselves want their child to fulfill their unfulfilled ambitions. This study provides the first experimental evidence to suggest that parents may desire their child to redeem their broken dreams.

Longitudinal associations between mothers' and fathers' sense of competence and children's externalizing problems: the mediating role of parenting.

This longitudinal study examined the bidirectional associations between parents' sense of competence and children's externalizing problems, mediation of these associations by parenting behaviors, and differences between mothers and fathers concerning these associations. A sample of 551 families with children (49.9% girls; mean age = 7.83 years, SD = 1.08) participated. We found children's externalizing problems to predict parents' sense of competence 6 years later, both directly and, for mothers but not for fathers, indirectly through inept discipline. Parents' sense of competence did not predict children's externalizing problems, either directly or indirectly via parenting behaviors. Some differences were found between mothers and fathers in the associations between parenting behaviors and sense of competence.

Effects of early prevention programs on adult criminal offending: a meta-analysis.

This meta-analysis investigated the long term effects of prevention programs conducted during early and middle childhood on criminal offending during adulthood. The analyses included 3611 participants in 9 programs. The effect size for adult criminal offending was significant, but small in magnitude (OR=1.26; 95% CI=1.06-1.50, p=.011). The effects of the programs on positive outcomes (academic attainment and involvement in productive activity, such as being engaged in school or work) were somewhat larger and more consistent than effects on crime (OR=1.36, 95% CI=1.20-1.55, p<.001). Several participant and program characteristics moderated the effectiveness of (early) prevention. Children who were more at-risk and those from a lower SES benefited more. Shorter, but more intensive programs, and programs that focus on social and behavioral skills, rather than on academic skills or family support, tend to produce larger effects. Taken together, these results indicate that early prevention programs can help put children on a more positive developmental trajectory that is maintained into adulthood, but there is still no convincing evidence that they can prevent adult crime. Implications of the findings for research, policy and clinical practice are discussed.
