Patterns of mother-infant interaction and attachment: A cluster-analytic approach

This study examined stability and change in patterns of mother-infant interaction between 5 and 10 months and their relation to attachment security at 18 months. Cluster analysis was used to identify patterns of dyadic interaction. There was significant, but not substantial, stability in cluster membership from 5 to 10 months. For females, being in the most optimal cluster at 5 months related to subsequent attachment security, regardless of the 10-month pattern of interaction. For males, who were significantly more likely to be insecure than females, insecure attachment was predicted by negative change from 5 to 10 months (moving from a more optimal to a less optimal cluster).     

Maternal regulation of infant reactivity from 2 to 6 months

Previous research has investigated the effect of maternal soothing behaviors on reducing infant reactivity but not the differential effects of specific maternal behaviors on infant stress responses. The present study investigated maternal regulation of 2- and 6-month-olds' responses to an inoculation and found a significant decline with age in both the intensity and duration of infants' crying. Maternal affection and touching decreased from 2 to 6 months, whereas maternal vocalizing and distraction behaviors increased. At both ages, the combination of maternal holding/rocking and vocalizing was associated with decreases in all levels of infant reactivity. Neither strategy alone, however, was found to be effective. Feeding/ pacifying behaviors were effective only when initial distress was at a low or moderate level, which suggests that the effectiveness of maternal regulatory behaviors may depend on the intensity of infants' crying.     

Infant temperament and maternal parenting self-efficacy predict child weight outcomes

Relationships between infant negative reactivity and self-regulation, parenting self-efficacy, and child weight outcomes were examined. Greater observed negative reactivity predicted more child weight gain when mothers had lower parenting self-efficacy. Lower mother-reported self-regulation predicted a greater child weight status. Results highlight potential early risk/protective factors.     

Heterogeneity in Maltreated and Non‐maltreated Preschool Children's Inhibitory Control: The Interplay Between Parenting Quality and Child Temperament

This study examined the contribution of child temperament, parenting, and their interaction on inhibitory control development in a sample of maltreated and non‐maltreated preschool children. One hundred and eighteen mother–child dyads were drawn from predominantly low‐income, rural communities. Dyads participated in a laboratory session in which maternal warm autonomy support, warm guidance, and strict/hostile control were observationally coded during a joint teaching task. Independent assessments of children's inhibitory control were obtained, and observers rated children's temperament. After relevant covariates, including income, maternal education, and child age and IQ were controlled for, there were no differences between the maltreatment and non‐maltreatment groups in either children's inhibitory control or mothers' behaviours in the laboratory session. Even after much of the variance in children's inhibitory control was accounted for from the covariates, children's temperamental negativity moderated the effects of warm autonomy support on inhibitory control in both maltreatment and non‐maltreatment groups. Temperamentally negative children whose mothers displayed more warm autonomy support showed greater inhibitory control, at levels on par with low‐negative children. Findings suggest that heterogeneity in children's self‐regulation may be due in part to individual differences in sensitivity to caregiver support for children's independence, even among those exposed to maltreatment.

Estimation of nonlinear mixed-effects continuous-time models using the continuous-discrete extended Kalman filter

Many intensive longitudinal measurements are collected at irregularly spaced time intervals, and involve complex, possibly nonlinear and heterogeneous patterns of change. Effective modelling of such change processes requires continuous-time differential equation models that may be nonlinear and include mixed effects in the parameters. One approach of fitting such models is to define random effect variables as additional latent variables in a stochastic differential equation (SDE) model of choice, and use estimation algorithms designed for fitting SDE models, such as the continuous-discrete extended Kalman filter (CDEKF) approach implemented in the dynr R package, to estimate the random effect variables as latent variables. However, this approach's efficacy and identification constraints in handling mixed-effects SDE models have not been investigated. In the current study, we analytically inspect the identification constraints of using the CDEKF approach to fit nonlinear mixed-effects SDE models; extend a published model of emotions to a nonlinear mixed-effects SDE model as an example, and fit it to a set of irregularly spaced ecological momentary assessment data; and evaluate the feasibility of the proposed approach to fit the model through a Monte Carlo simulation study. Results show that the proposed approach produces reasonable parameter and standard error estimates when some identification constraint is met. We address the effects of sample size, process noise variance, and data spacing conditions on estimation results.     

Mother parity as a main and moderating influence on early mother-infant interaction

This study investigated main and moderating effects of mother parity on maternal attitudes and behaviors. In a sample of 87 mothers with 5-month-old infants, relations between determinants of parenting (maternal personality, marital quality, infant negative emotionality) and maternal behavior and attitudes (sensitivity, self-efficacy, mother-reported infant temperament) were examined as a function of parity. Results revealed both main and moderating effects of parity. Multiparous mothers reported higher self-efficacy, whereas primiparous mothers reported more of an increase in marital ambivalence following the baby's birth. The relations of self-efficacy, sensitivity, and mother-reported infant temperament to a laboratory measure of infant crying all differed by parity. In addition, for primiparous mothers, negative personality traits related to reported infant temperament, and for multiparous mothers, marital ambivalence and maternal sensitivity appeared to reflect a compensatory process. These results suggest that parity contributes to explaining how differing family systems influence development during infancy.     

Temperamental surgency and emotion regulation as predictors of childhood social competence

The primary aims of the current study were to longitudinally examine the direct relationship between children's temperamental surgency and social behaviors as well as the moderating role of children's emotion regulation. A total of 90 4.5-year-old children participated in a laboratory visit where children's temperamental surgency was rated by experimenters and children's emotion regulation abilities were assessed. The summer before entry into first grade, children's social behaviors with unfamiliar peers were observed in the laboratory and mothers completed a questionnaire about children's social behaviors. Supporting our hypotheses, results revealed that children high in temperamental surgency developed more negative peer behaviors, whereas children low in temperamental surgency were more likely to develop behavioral wariness with peers. Emotion regulatory behaviors were found to moderate the relation between temperamental surgency and aggression, where high-surgent children who showed high levels of social support seeking were less likely to be rated by their mothers as high in aggression. Furthermore, results revealed that low-surgent children who showed high levels of distraction/self-soothing were more likely to show behavioral wariness around unfamiliar peers, whereas high-surgent children who used more distraction/self-soothing behaviors were rated by their mothers as lower in social competence.     

Development of approach and inhibition in the first year: parallel findings from motor behavior,temperament ratings and directional cardiac response

A group of 139 infants was observed at 6 and 12 months. Approach and inhibition were measured via latencies to touch low– and high–intensity objects, directional cardiac response to low– and high–intensity sounds and maternal ratings of positive and fearful emotionality. Inhibition showed considerable increases in all three domains from 6 to 12 months. Also reflecting increases in inhibitory processes, correlations between individual infants’ responses to low– and high–intensity sounds were significantly smaller at 12 than at 6 months. Limited cross–domain validity was obtained linking large cardiac decelerations, low latencies to reach for toys and high ratings of positive emotionality. These findings are consistent with previous reports documenting relatively greater gains in inhibition than approach during the second half of the first year. Modest cross–domain consistency indicates separate mechanisms may moderate approach and inhibition in the three different realms.
