Maternal Anxiety and Toddler Inhibited Temperament Predict Maternal Socialization of Worry

Assessing anxiety problems in a community sample during toddlerhood: The impact of child temperament and maternal intrusiveness

Previous research indicates that child temperament and maternal behaviors are related to internalizing behaviors in children. We assessed whether maternal intrusiveness (MI) observed at 10-months would moderate the impact of temperamental fear and the impact of inhibitory control (IC) at 24 months on anxiety problems at 36 months. A mother-child interaction task was coded for MI. Behavioral tasks were given to assess children's IC. Parents completed questionnaires about their children's temperamental fear and anxiety problems. Results showed that greater temperamental fear reported at 24 months predicted greater anxiety problems reported at 36 months, regardless of MI levels. Lower levels of IC at 24 months predicted more anxiety problems reported at 36 months when children experienced greater MI. These findings illustrate the importance of examining both intrinsic and extrinsic factors, independently and interactively, that contribute to children's anxiety problems in toddlerhood.

IQ, parent- and self-reports of child anxiety and salivary cortisol in a sample of children with autism spectrum disorder

This study examined the relation between IQ, parent-reported child anxiety, and salivary cortisol levels in youth with autism spectrum disorder (ASD) with a wide range of intellectual abilities using a prospective design. Results showed that IQ at time 1 (T1) positively predicted parent-reports of child anxiety at time 2 (T2); however, IQ at T1 negatively predicted cortisol levels from saliva samples taken at a research laboratory at T2. Parent reports of child anxiety at T1 and T2 were not associated with cortisol levels at T2. Implications for the assessment of anxiety in youth with ASD are discussed.

Maternal Worry Socialization and Toddler Inhibited Temperament: Transactional Associations and Stability across Time

Caregiver socialization of child emotions has consequences for both typical development and anxiety risk, with caregivers' non-supportive responses to worry perhaps especially salient to children's anxiety development. Children, in turn, impact the caregiving environment they receive through their temperament. We investigated transactional relations between maternal non-supportive responses to child worry (mother-reported) and two differently-measured child inhibited temperament indices (i.e., mother-perceived child inhibition to novelty, laboratory-observed child dysregulated fear) in a sample of 136 predominantly non-Hispanic, White mother-toddler dyads. Worry socialization and mother-reported inhibition to novelty were measured at each of three time points (toddler age 2, 3, 4 years), and dysregulated fear was measured at ages 2 and 3. Constructs showed stability across time, with effect sizes ranging from medium to large. Child inhibited temperament measures positively correlated within time point at ages 2 and 3, and laboratory-observed child dysregulated fear predicted mothers' later perceptions of their children's inhibition to novelty. At toddler age 2, mothers of children showing more dysregulated fear reported responding more non-supportively to worry. However, when controlling for one another, more mother-perceived child inhibition to novelty and less laboratory-observed child dysregulated fear at age 3 predicted mothers' greater non-supportive worry responses at child age 4. There was an indirect effect across time, such that children's greater laboratory-observed dysregulated fear predicted their mothers' heightened perceptions of inhibited temperament, which in turn predicted mothers' greater non-supportive worry responses. Findings lend support to anxiety-relevant construct stability in toddlerhood, as well as child-elicited, rather than parent-elicited, associations across time.

Parent-to-Child Anxiety Transmission Through Dyadic Social Dynamics: A Dynamic Developmental Model

The intergenerational transmission of psychopathology is one of the strongest known risk factors for childhood disorder and may be a malleable target for prevention and intervention. Anxious parents have distinct parenting profiles that impact socioemotional development, and these parenting effects may result in broad alterations to the biological and cognitive functioning of their children. Better understanding the functional mechanisms by which parental risk is passed on to children can provide (1) novel markers of risk for socioemotional difficulties, (2) specific targets for intervention, and (3) behavioral and biological indices of treatment response. We propose a developmental model in which dyadic social dynamics serve as a key conduit in parent-to-child transmission of anxiety. Dyadic social dynamics capture the moment-to-moment interactions between parent and child that occur on a daily basis. In shaping the developmental trajectory from familial risk to actual symptoms, dyadic processes act on mechanisms of risk that are evident prior to, and in the absence of, any eventual disorder onset. First, we discuss dyadic synchrony or the moment-to-moment coordination between parent and child within different levels of analysis, including neural, autonomic, behavioral, and emotional processes. Second, we discuss how overt emotion modeling of distress is observed and internalized by children and later reflected in their own behavior. Thus, unlike synchrony, this is a more sequential process that cuts across levels of analysis. We also discuss maladaptive cognitive and affective processing that is often evident with increases in child anxiety symptoms. Finally, we discuss additional moderators (e.g., parent sex, child fearful temperament) that may impact dyadic processes. Our model is proposed as a conceptual framework for testing hypotheses regarding dynamic processes that may ultimately guide novel treatment approaches aimed at intervening on dyadically linked biobehavioral mechanisms before symptom onset.

Bidirectional effects of toddler temperament and maternal overprotection on maternal and child anxiety symptoms across preschool

INTRODUCTION

Existing research highlights interactions among child temperament, parents' own anxiety symptoms, and parenting in predicting increased risk for anxiety symptom development. Theoretical models of child-elicited effects on parents have proposed that parents' behaviors are likely not independent of children's temperament; fearful children likely elicit more protective responses from parents and these parenting behaviors reinforces child anxiety and parents' own anxiety.

METHOD

The current study tests this model and examines whether there are bidirectional influences between early fearful temperament (i.e., dysregulated fear [DF]), maternal overprotection, and subsequent trajectories of maternal and child anxiety symptoms across early childhood. A total of 166 children and mothers participated in a multimethod, longitudinal study of temperament risk from 2 to 6 years.

RESULTS

Results largely support our hypotheses, replicating and extending the prior literature. DF was associated with more maternal overprotective behavior, subsequent child anxiety symptoms, and maternal anxiety symptoms. Moreover, there were indirect (mediated) associations through maternal overprotective behavior and both child and mother anxiety symptoms.

CONCLUSION

Results support the hypothesis that intergenerational transmission of anxiety was meditated through maternal behaviors and that the child-driven temperament effects are central to trajectories of child and maternal anxiety trajectories.
