Disclosure ▪ No financial disclosures or conflicts of interest

Objectives ▪ Review literature on selected risk factors for childhood anxiety: temperament, parenting, & gender ▪ Present results from a study examining the roles of children’s temperamental self-regulatory abilities (effortful control), caregiving experiences (maternal intrusiveness), & gender in the translation of early temperamental risk (behavioral inhibition) to anxiety in mid-childhood ▪ Discuss conclusions regarding risk and resilience in early childhood & potential clinical implications

Temperament ▪ Constitutionally-based individual differences in reactivity & self-regulation [9] ▪ Results from a confluence of genetic & early environmental factors [9, 12] ▪ Reactivity ▪ Physiological, emotional, & behavioral responsivity to change [9] ▪ Individual differences apparent shortly after birth [10]

▪ Self-Regulation ▪ Modulation of reactivity via executive control of attention & behavior [9] ▪ Emerges toward end of 1st year, develops gradually through preschool years & beyond [11]

Temperamental Reactivity & Anxiety ▪ Behavioral Inhibition (BI) ▪ Form of reactivity – fear, hypervigilance, & withdrawal in response to novelty [15, 16]

▪ ~15% of typically-developing children [15] ▪ Moderately stable, ~50% continuity [22, 23]

▪ Behavioral Inhibition & Anxiety ▪ Many common features [17] ▪ Regarded as independent constructs [1] ▪ BI is a risk factor for clinically significant anxiety in childhood & adolescence [17-20]

Temperamental Self-Regulation & Anxiety ▪ Effortful Control (EC) ▪ Active & voluntary recruitment of higher order cognitive processes to modulate reactivity [9] ▪ Attentional Control ▪ Inhibitory Control

▪ EC plays an essential role in Emotion Regulation ▪ Developmental progression: Passive, other-dependent strategies  active, autonomous strategies [24, 25] ▪ Passive Coping (e.g., comfort-seeking) – reinforces fear & avoidance [15, 28, 29] ▪ Active Coping (e.g., self-distraction) – dependent on EC [25-27]

▪ EC is linked with positive social-emotional outcomes [13, 14, 27, 30] ▪ Negatively linked with anxiety [15]

Reactivity, Self-Regulation, & Anxiety ▪ BI may shape the development of effortful control ▪ Attentional rigidity [17, 31, 32] ▪ Withdrawal & avoidance – reduced opportunity to self-regulate [15, 33]

▪ BI children who learn to modulate via EC may be protected from anxiety ▪ Hypothesis 1: Partial Mediation Effortful Control

Environmental Influences ▪ Caregiving environment may impact translation of BI to anxiety [7] ▪ Parents play a primary role in socialization & development of emotion regulation [34, 35] ▪ Parenting may also contribute to ineffective emotion regulation [24]

▪ ‘Parental Control’ is linked with child anxiety ▪ Broad construct, inconsistently defined ▪ Maternal Intrusiveness (MI) – excessive interference, redirection, & structuring; imposition of mother’s agenda despite child signals

▪ Thought to reduce actual/perceived ability to self-regulate & master challenges [36, 48] ▪ Support in school-age child samples; findings are rare & inconsistent in early childhood [44-47]

Environmental Influences  ‘Goodness of Fit’ perspective [49] – MI may be a poor fit for BI children  In greater need of EC to regulate reactivity  MI may interfere with development & deployment of EC

Maternal Intrusiveness

▪ Hypothesis 2: Moderated Mediation ▪ Indirect pathway moderated by MI ▪ Mediating effect only in context of MI

 Child Care (CC)  Exposure to high quality, non-maternal CC may have a buffering role [7, 23, 50-52]  Explored effects of CC type & quality on indirect pathway – results not presented due to inconsistent fit to data

Gender, Temperament, & Anxiety ▪ Gender differences in temperament and anxiety ▪ Girls demonstrate greater BI, EC, & anxiety [10, 53-55]

▪ Gender differences in socialization of emotion regulation ▪ Parents’ differential reinforcement of inhibited/fearful behavior in girls & assertive behavior in boys [55-61]

Methods

Participants & Data Collection ▪ National Institute of Child Health and Human Development (NICHD) Study of Early Child Care and Youth Development (SECCYD) [62-64] ▪ Prospective, longitudinal study of developmental outcomes associated w/ child care ▪ Began in 1991, followed children from birth to age 15 ▪ Recruitment from hospitals over 10 month period from 10 sites across the U.S. ▪ 8,986 mothers recruited; 5,416 eligible & willing to be contacted; 3,015 randomly selected to be contacted; 1,525 reached by phone; 1,364 participated

▪ Enrolled children: 705 (52%) male; 659 (48%) female ▪ Wide range of ethnic, educational, & economic backgrounds ▪ Data collected from multiple informants, in multiple settings, using multiple methods

▪ Present study uses data from ages 6 months to approximately 6 years

Measures ▪ Temperament (6 months) ▪ Revised Infant Temperament Questionnaire, [65] Approach (reversed); mother-report (α = .75)

▪ Maternal Intrusiveness (15 & 24 months) ▪ Observations of mother-child interactions in semi-structured tasks – coded for MI; scores averaged & dichotomized as presence or absence of intrusiveness

▪ Effortful Control (54 months) ▪ Continuous Performance Test, [66] Hits Minus False Alarms ▪ Delay of Gratification Task,[67] Total Time Waited ▪ Children’s Behavior Questionnaire,[68] Attention Focusing (α = .74) & Inhibitory Control (α = .75); mother-report ▪ EC composite – averaged Z-scores

▪ Anxiety (Kindergarten) ▪ Child Behavior Checklist,[69] Anxiety Scale;[70] mother-report (α = .73)

◦ Also evidence for differential effects of MI on indirect pathway for boys & girls – results not presented here

Discussion ◦ Early BI emerged as a significant, but not clinically meaningful predictor of child anxiety ◦ More proximal intrinsic & extrinsic risk factors play more important roles

◦ Findings support the hypothesis that diminished/ineffective deployment of effortful control is one mechanism linking early BI to childhood anxiety, but only in the absence of intrusive parenting & only for girls ◦ First empirical support for this indirect pathway in early childhood ◦ Complements & extends recent similar finding in an older sample (aged 7-10) [72] ◦ Suggests circumstances under which this pathway is apparent

Discussion ◦ Apparent only for girls – may be due to socialization of emotion regulation ◦ Parents’ responses may disrupt BI-anxiety pathway in boys; less dependent on EC

◦ Disappeared in the context of MI – less intuitive ◦ Literature on child anxiety & parental control has focused mainly on school-age children & adolescents [36] ◦ Greater definitional specificity may be needed regarding MI/parental control in early childhood

◦ MI may not be a poor fit for BI children until later on ◦ Some degree of ‘intrusive’ behavior may facilitate exposure to developmentally appropriate experiences [16, 41, 76, 77]

◦ Potential clinical implications ◦ Interventions to develop EC may protect against anxiety for BI young girls ◦ Family-based interventions to reduce MI may not be appropriate for BI young children ◦ Additional research is needed
