Early intervention for inhibited young children: a randomized controlled trial comparing the Turtle Program and Cool Little Kids

Does intolerance of uncertainty predict child generalised anxiety? A longitudinal study

Intolerance of uncertainty (IU) is the tendency to find uncertainty distressing. IU is related to anxiety in adults and youth but it is unclear whether IU plays a maintenance or causal role, particularly across childhood. Our research examined whether: (1) IU is associated with generalised anxiety in preschool-aged children; (2) IU in preschool-aged children is associated with the trajectory of generalised anxiety into middle childhood; and (3) IU is associated with the trajectory of internalising symptoms and externalising symptoms over time. Parents completed questionnaires (child anxiety, IU, internalising and externalising symptoms) about their children at three timepoints when their child was: 3-4 years old (n = 180); 5-7 years old (n = 162); and 8-10 years old (n = 148). Those with higher IU had higher concurrent generalised anxiety, internalising and externalising symptoms at each measurement point. Preschoolers with higher IU, relative to lower IU, had, on average, higher generalised anxiety across childhood. Unexpectedly though, children who were higher in IU as preschoolers were more likely to show a decrease in generalised anxiety over time. These findings indicate that IU is a consistent correlate of generalised anxiety, internalising and externalising symptoms, but that it may not play a causal role in the onset of generalised anxiety in children.

Co-Changes and Mutual Influences of Fearful Temperament, Task Switching, and Maternal Intrusiveness in Early Childhood

This study employed latent change score models to examine the co-changes and mutual influences of fearful temperament, task switching, and maternal intrusiveness in early childhood. Participants included 335 children (171 boys, 164 girls; Mage = 3.09 years at baseline; 77.3% White, 14.0% Black, 8.4% multiracial, 0.3% Asian, 7.8% Hispanic) and their mothers. Higher levels of maternal intrusiveness at 36 months predicted a smaller increase in children's task switching between 36 and 48 months. Higher levels of task switching at 36 months predicted a larger decrease in fearful temperament. The changes between task switching and fearful temperament co-occurred; as the degree of task switching increased, fearful temperament decreased, or vice versa. Family-oriented interventions that reduce maternal intrusiveness may facilitate children's improvements in task switching, which is closely associated with the development of a fearful temperament.

Supporting parents to reduce children's anxiety: A meta-analysis of interventions and their theoretical components

Parent-focused interventions hold promise for reducing child anxiety, but their content varies greatly, and little is known on the intervention content. We estimated the effects of parent-focused interventions on child anxiety and the most effective combinations of theoretical components. We searched PsycINFO, Medline, and Web of Science in October 2022 for randomized trials on parent-focused interventions to reduce children's anxiety. We used robust variance estimation to estimate main effects and differential effects by individual theoretical components, and network meta-analysis to estimate the effects of clusters of components (preregistration: PROSPERO CRD42022362983). We identified 26 studies (k = 157, N = 4098). Parent-focused interventions had a significant medium effect on children's anxiety (d = -0.59; 95% CI [-0.92, -0.26]). Interventions used seven theoretically distinct components. No significant differential effects were found, but all clusters of components that produced significant effects contained a behavioral component. Adding cognitive and emotional components to behavioral components seemed beneficial. This meta-analysis highlights the potential of parent-focused interventions for children's anxiety, and of behavioral components in particular, but is limited by the very low certainty of evidence. More high-quality research is needed to understand the exact potential of parent-focused interventions on children's anxiety, and their most effective components.

Understanding the Development of Chronic Loneliness in Youth

Loneliness becomes more prevalent as youth transition from childhood into adolescence. A key underlying process may be the puberty-related increase in biological stress reactivity, which can alter social behavior and elicit conflict or social withdrawal ("fight-or-flight" behaviors) in some youth, but increased prosocial ("tend-and-befriend") responses in others. We propose an integrative theoretical model that identifies the social, personality, and biological characteristics underlying individual differences in social-behavioral responses to stress. This model posits a vicious cycle whereby youth who respond to stress with "fight-or-flight" tendencies develop increasing and chronic levels of loneliness across adolescence, whereas youth who display "tend-and-befriend" behaviors may be buffered from these consequences. Based on research supporting this model, we propose multiple intervention avenues for curtailing the prevalence of loneliness in adolescence by targeting key factors involved in its development: social relationships, personality, and stress-induced behavioral and biological changes.

Testing reciprocal associations between child anxiety and parenting across early interventions for inhibited preschoolers

BACKGROUND

Given the robust evidence base for the efficacy of evidence-based treatments targeting youth anxiety, researchers have advanced beyond efficacy outcome analysis to identify mechanisms of change and treatment directionality. Grounded in developmental transactional models, interventions for young children at risk for anxiety by virtue of behaviorally inhibited temperament often target parenting and child factors implicated in the early emergence and maintenance of anxiety. In particular, overcontrolling parenting moderates risk for anxiety among highly inhibited children, just as child inhibition has been shown to elicit overcontrolling parenting. Although longitudinal research has elucidated the temporal unfolding of factors that interact to place inhibited children at risk for anxiety, reciprocal transactions between these child and parent factors in the context of early interventions remain unknown.

METHOD

This study addresses these gaps by examining mechanisms of change and treatment directionality (i.e., parent-to-child vs. child-to-parent influences) within a randomized controlled trial comparing two interventions for inhibited preschoolers (N = 151): the multicomponent Turtle Program ('Turtle') and the parent-only Cool Little Kids program ('CLK'). Reciprocal relations between parent-reported child anxiety, observed parenting, and parent-reported accommodation of child anxiety were examined across four timepoints: pre-, mid-, and post-treatment, and one-year follow-up (NCT02308826).

RESULTS

Hypotheses were tested via latent curve models with structured residuals (LCM-SR) and latent change score (LCS) models. LCM-SR results were consistent with the child-to-parent influences found in previous research on cognitive behavioral therapy (CBT) for older anxious youth, but only emerged in Turtle. LCS analyses revealed bidirectional effects of changes in parent accommodation and child anxiety during and after intervention, but only in Turtle.

CONCLUSION

Our findings coincide with developmental transactional models, suggesting that the development of child anxiety may result from child-to-parent influences rather than the reverse, and highlight the importance of targeting parent and child factors simultaneously in early interventions for young, inhibited children.

Examining the Relations Between Children's Vagal Flexibility Across Social Stressor Tasks and Parent- and Clinician-Rated Anxiety Using Baseline Data from an Early Intervention for Inhibited Preschoolers

Early behavioral inhibition (BI) is a known risk factor for later anxiety disorder. Variability in children's parasympathetic nervous system (PNS) functioning may provide insight into the substantial heterogeneity in anxiety outcomes for children high in BI. However, gaps persist due to an over-reliance on static measures of functioning, which limits our ability to leverage PNS functioning to identify risk for anxiety. We address these gaps using baseline data from an early intervention study of inhibited preschoolers by characterizing vagal flexibility (VF), an index of non-linear change in PNS functioning, across social stressor tasks and by examining the associations between VF and anxiety. One hundred and fifty-one parents and their 3.5- to 5-year-old children were selected on the basis of BI to participate in an early intervention program (ClinicalTrials.gov registration: NCT02308826). A structural equation modeling framework was used to model children's VF across tasks designed to mimic exposure to novel social interactions and to test the predictive links between VF and anxiety. Children who showed less VF, characterized by less suppression and flatter recovery, were rated by both parents and clinicians as more anxious. Moreover, a multiple group model showed that children meeting diagnostic criteria for social anxiety disorder demonstrated significantly less VF across social stressor tasks. Among inhibited youth, reduced VF is a risk factor for anxiety and may reflect an individual's reduced capacity to actively cope with external demands. Study results contribute to our understanding of the regulatory processes underlying risk for anxiety in early childhood.

Comparison of behaviorally inhibited and typically developing children's play behaviors in the preschool classroom

Introduction

Behavioral inhibition (BI) is a temperamental trait characterized by a bias to respond with patterns of fearful or anxious behavior when faced with unfamiliar situations, objects, or people. It has been suggested that children who are inhibited may experience early peer difficulties. However, researchers have yet to systematically compare BI versus typically developing children's observed asocial and social behavior in familiar, naturalistic settings.

Method

We compared the in-school behaviors of 130 (M = 54 months, 52% female) highly inhibited preschoolers (identified using the parent-reported Behavioral Inhibition Questionnaire) to 145 (M = 53 months, 52% female) typically developing preschoolers. Both samples were observed on at least two different days for approximately 60 min. Observers used the Play Observation Scale to code children's behavior in 10-s blocks during free play. Teachers completed two measures of children's behavior in the classroom.

Results

Regression models with robust standard errors controlling for child sex, age, and weekly hours in school revealed that preschoolers identified as BI engaged in significantly more observed reticent and solitary behavior, and less social play and teacher interaction than the typically developing sample. Children with BI also initiated social interaction with their peers and teachers less often than their counterparts who were not inhibited. Teachers reported that children identified as BI were more asocial and less prosocial than their non-BI counterparts.

Discussion

Significantly, the findings indicated that inhibited children displayed more solitude in the context of familiar peers. Previous observational studies have indicated behavioral differences between BI and unfamiliar typical age-mates in novel laboratory settings. Children identified as BI did not receive fewer bids for social interaction than their typically developing peers, thereby suggesting that children who are inhibited have difficulty capitalizing on opportunities to engage in social interaction with familiar peers. These findings highlight the need for early intervention for children with BI to promote social engagement, given that the frequent expression of solitude in preschool has predicted such negative outcomes as peer rejection, negative self-regard, and anxiety during the elementary and middle school years.

Preliminary perceived intervention changes and engagement in an evidence-based program targeted at behavioral inhibition during early childhood, delivered in-person and online

Introduction

Behavioral inhibition during early childhood is one of the strongest risk factors for the development of later anxiety disorders. Recently developed in-person interventions that target both young children who are highly inhibited and their parents (e.g., the Turtle Program), have decreased children's anxiety and have increased social participation in the peer group. However, researchers have yet to examine the effects of intervention mode of delivery. In the present study, we compared the pre-to post-intervention changes in child and parenting functioning of families participating in the Turtle Program, delivered in-person and online with those changes made in families allocated to a waiting-list condition; compared session attendance, homework completion and satisfaction with the intervention outcomes of families involved in the Turtle Program, delivered in-person and online; and explored the predictive role of parenting and child factors in session attendance, homework completion and satisfaction with the outcomes of families involved in the Turtle Program, depending on the mode of delivery (in-person vs. online).

Method

Fifty-seven parents of highly inhibited preschoolers (3-5 years), with no diagnosis of selective mutism or developmental disorders, who were randomly allocated to waiting-list (n = 20), Turtle Program delivered in-person (n = 17) and online (n = 20) conditions completed the Portuguese versions of the Behavioral Inhibition Questionnaire, the Preschool Anxiety Scale, the Social Behavior and Competence Scale, the Modified Child-Rearing Practices Questionnaire at pre- and post-intervention assessment. Parents also completed the Preschool Shyness Study Satisfaction Survey at post-intervention assessment.

Results

Independent of intervention mode of delivery, generalized equation estimates revealed a reduction in children's total anxiety symptoms and an improvement in parental nurturing behaviors. Child anxiety and social competence at pre-assessment were the most prominent predictors of session attendance and satisfaction with post-intervention child and parenting outcomes.

Discussion

Overall, this study showed that parents in both intervention conditions perceived comparable positive changes in child functioning from pre- to post-intervention assessment and similar levels of session attendance, homework completion, and satisfaction. Significantly, however, perceived satisfaction with post-intervention child and parenting outcomes was higher, when children were reported to display higher SEL skills at baseline, independent of the intervention mode of delivery.

Annual Research Review: Developmental pathways linking early behavioral inhibition to later anxiety

Behavioral Inhibition is a temperament identified in the first years of life that enhances the risk for development of anxiety during late childhood and adolescence. Amongst children characterized with this temperament, only around 40 percent go on to develop anxiety disorders, meaning that more than half of these children do not. Over the past 20 years, research has documented within-child and socio-contextual factors that support differing developmental pathways. This review provides a historical perspective on the research documenting the origins of this temperament, its biological correlates, and the factors that enhance or mitigate risk for development of anxiety. We review as well, research findings from two longitudinal cohorts that have identified moderators of behavioral inhibition in understanding pathways to anxiety. Research on these moderators has led us to develop the Detection and Dual Control (DDC) framework to understand differing developmental trajectories among behaviorally inhibited children. In this review, we use this framework to explain why and how specific cognitive and socio-contextual factors influence differential pathways to anxiety versus resilience.

Behavioural inhibition and early neural processing of happy and angry faces interact to predict anxiety: a longitudinal ERP study

Limited prospective research has examined whether attention biases to emotion moderate associations between Behavioural Inhibition (BI) and anxiety in preschool-aged children. Furthermore, there has been an over-reliance on behavioral measures in previous studies. Accordingly, we assessed anxiety in a sample of preschool-aged children (3-4 years) at baseline, and again approximately 6 and 11 months later, after they started school. At baseline, children completed an assessment of BI and an EEG task where they were presented with angry, happy, and neutral faces. EEG analyses focused on ERPs (P1, P2, N2) associated with specific stages of attention allocation. Interactions between BI and emotion bias (ERP amplitude for emotional versus neutral faces) were found for N2 and P1. For N2, BI was significantly associated with higher overall anxiety when an angry bias was present. Interestingly for P1, BI was associated with higher overall anxiety when a happy bias was absent. Finally, interactions were found between linear time and happy and angry bias for P1, with a greater linear decrease in anxiety over time when biases were high. These results suggest that attention to emotional stimuli moderates the BI-anxiety relationship across early development.

Targeting risk factors for inhibited preschool children: An anxiety prevention program

OBJECTIVE

Children with a behaviorally inhibited temperament during early childhood have been shown to have an increased risk for developing anxiety disorders. This study evaluated the efficacy of an anxiety prevention program aimed at reducing the risk of anxiety in behaviorally inhibited preschool children.

METHOD

Participants were 86 children aged 41-57 months and their mothers. Children were selected if their mothers reported high levels of child behavioral inhibition on a screening measure. Participants were randomly allocated to a nine-session intervention or a waitlist control condition. Mothers and children both participated in the intervention.

RESULTS

At follow-up, the intervention group had significantly fewer clinician-rated child anxiety disorders and fewer mother-reported child anxiety symptoms than at baseline but this change was not significantly different to the change seen in the waitlist control group.

CONCLUSIONS

On average, across the course of the study, anxiety decreased in all children irrespective of group. A number of potential reasons for this are discussed along with implications for research and clinical practice.
