This study used structural equation modeling to examine the relationship between multiple sources of social support (e.g., partner, family, and friends), optimism, and well-being among mothers of children with ASD. Social support was examined as a mediator and moderator of the optimism-maternal well-being relationship. Moreover, the role of optimism as a mediator of the social support-maternal well-being relationship was also evaluated. Results revealed that family support was associated with increased optimism that, in turn, predicted higher levels of positive maternal outcomes and lower levels of negative maternal outcomes. In addition, partner and friend support were directly associated with maternal outcomes. Implications for the development of interventions directed at increasing the quality of social support networks are discussed.

Although it is well accepted that parents greatly impact infant development, it is less clear which factors impact change in quantity and quality of parenting across infancy. This longitudinal study (N = 120 families) investigated how infant temperament and marital adjustment related to trajectories of mother and father involvement and sensitivity across infancy using multilevel models. Parental involvement (caregiving and play), infant temperament (surgency, negative affectivity, regulation), and marital adjustment were assessed from questionnaires when the infant was 3, 5, 7, 12, 14, and 20 months of age; parental sensitivity was coded from two episodes of the Still‐Face Paradigm in early infancy (3, 5, and 7 months). On average, mothers showed higher levels of caregiving, play, and sensitivity than fathers. Mother caregiving, play, and sensitivity increased over time. Father caregiving and play also increased over time, whereas sensitivity did not change with age. Happier marriages were related to increased play for both mothers and fathers. Infant surgency was also significantly related to caregiving, play, and sensitivity trajectories for mothers but not fathers. Findings are discussed in relation to parenting roles and family dynamics.

This study examined the extent to which infant and parent response trajectories during the Still-Face-Paradigm (SFP) in early infancy predicted later infant-mother and infant-father attachment. Families (n = 135) participated in the SFP when infants were 3, 5, and 7 months and the Strange Situation when infants were 12 (mothers) and 14 months (fathers). Multilevel models showed that parent sensitivity assessed during the SFP was related to infants’ affective and behavioral response trajectories during the SFP, and that sensitivity and infant response trajectories predicted attachment. Results from the present study support the notion that parent and infant responses in the SFP with mothers and fathers during Bowlby’s Attachment in the Making phase provide insight into the developing parent-child attachment relationship.

The present study investigated temporal associations between putative emotion regulation strategies and negative affect in 20-month-old toddlers. Toddlers’ parent-focused, self-distraction, and toy-focused strategies, as well as negative affect, were rated on a second-by-second basis during laboratory parent-toddler interactions. Longitudinal mixed-effects models were conducted to determine the degree to which behavioral strategy use predicts subsequent negative affect and negative affect predicts subsequent strategy use. Results with mother-toddler and father-toddler dyads indicated that parent-focused strategies with an unresponsive parent were followed by increases in negative affect, whereas toy-focused strategies were followed by decreases in negative affect. Results also indicated that toddler negative affect serves to regulate behavioral strategy use within both parent contexts.

The ability to effectively regulate emotions is a critical component of early socio-emotional development. This longitudinal study examined the developmental trajectories of emotion regulation in a sample of 3-, 5-, and 7-month-olds during an interaction with mothers and fathers. Infants’ negative affect and use of behavioral strategies, including distraction, self-soothing, and high intensity motor behaviors were rated during the still-face episode of the Still-Face Paradigm. Longitudinal mixed-effects models were tested to determine whether strategies were followed by an increase or decrease in negative affect. Results from mother-infant and father-infant dyads indicated that focusing attention away from the unresponsive parent and engaging in self-soothing behaviors were associated with a subsequent decline in negative affect and the strength of these temporal associations were stable across infancy. In contrast, high-intensity motor behaviors were followed by an increase in negative affect and this effect declined over time. No significant effects were found for the behavioral strategy of looking at the parent. Results underscore the importance of considering infant age and the social partner when studying the effectiveness of emotion regulatory strategies in early infancy.
