Nonmaternal care hours and temperament predict infants’ proximity-seeking behavior and attachment subgroups

Using the NICHD Early Childcare dataset (N = 1281), this study examined whether infant temperament and the amount of time infants spend in nonmaternal care independently predict (1) the likelihood that they seek comfort from their mother when needed and (2) placement in a particular subgroup of infant-mother attachment patterns. Mothers reported the number of hours their infant spent in nonmaternal care each month and their infant's difficulty adapting to novel stimuli at 6 months. The degree to which 15-month-old infants seek comfort from their mother during reunion episodes in the Strange Situation was observed using two behavioral scales (“proximity seeking” and “contact maintaining”). Their average score forms the outcome variable of “proximity-seeking behavior.” The other outcome variables were the subgroups of infant-mother attachment patterns: two subgroups for insecure babies (resistant and avoidant) and four subgroups for secure babies (B1, B2, B3, and B4). Easy adaptability to novel stimuli and long hours of nonmaternal care independently predicted a low level of proximity-seeking behavior. These predictors also increased the likelihood of an insecure infant being classified as avoidant (vs. resistant). A secure infant with these same predictors was most likely to be classified as B1, followed by B2, and then B3, with B4 being the least likely classification. Although previous studies using the NICHD dataset found that hours of nonmaternal care had no main effect on infants’ attachment security (vs. insecurity), this study demonstrates that hours of nonmaternal care predict the subcategories of infant-mother attachment.     

Happy babies,chatty toddlers: Infant positive affect facilitates early expressive,but not receptive language

Eighty-three mother–infant dyads participated in this study. Positive affect (PA) broadly, along with fine-grained aspects of PA, was measured at 10 months of age. Language was measured at 14 months. Infant PA predicted expressive, but not receptive, language. The implications of these findings are discussed.     

Overt and relational forms of reactive aggression in adolescents: Relations with temperamental reactivity and self-regulation

This study examined whether overt and relational forms of reactive aggression were differentially related to adolescents’ temperament. Measures of adolescents’ temperament and aggression were completed by 670 adolescents (369 females), ages 10–17, and their mothers. Effortful control and fearfulness were inversely associated only with reactive–overt aggression, whereas frustration proneness was more strongly linked with reactive–relational aggression. Furthermore, amongst younger adolescents, effortful control had a larger association with reactive–overt aggression when fearfulness was low, whereas frustration proneness had a stronger relation to reactive–relational aggression when effortful control was high. The differential relations between the two forms of reactive aggression (i.e., overt and relational) and effortful control or fearfulness are discussed with respect to variations in the riskiness and the social competence required to implement these aggressive actions.     

Temperament,coping, and involuntary stress responses in preadolescent children: the moderating role of achievement goal orientation

Background and objectives: Developmental theorists posit that temperament contributes to preadolescent’s stress response styles. Findings from empirical studies, however, have yielded mixed results, thus indicating a need to consider moderators of this relation. Utilizing an analytic framework guided by resiliency theory [Zimmerman, M. A. (2013). Resiliency theory: A strengths-based approach to research and practice for adolescent health. Health Education &; Behavior, 40, 381–383], this study examined achievement goal orientation as a moderator of the relation between temperament and stress response styles.

Methods: 96 preadolescent–parent dyads (M_age?=?10.30 years, range?=?9–12 years) participated in the study. Preadolescents reported on their achievement goal orientation, coping and involuntary stress responses (ISRs) styles and a parent reported on children’s temperament.

Results: Multiple regressions revealed that effortful control positively predicted preadolescent’s predominant use of engagement coping and negatively predicted predominance of ISRs, but only for children with a predominant mastery goal orientation. For preadolescents with a predominant performance goal orientation, effortful control negatively predicted the predominant use of engagement coping and positively predicted predominance of ISRs. Negative affectivity and its interaction with goal orientation did not predict coping or ISR styles.

Conclusions: Findings suggest that a predominant mastery goal orientation may function as a promotive factor by enhancing the contribution of effortful control to engagement coping styles and buffering against unmanaged reactivity.     

Continuity of temperament from infancy to middle childhood

Continuity of temperament from 6 months (the IBQ) to 5.5 years (the CBQ) was explored in Finnish children (n = 231) within the theoretical framework deviced by Rothbart. Activity level, smiling and laughter, distress to limitations and fear showed significant differential homotypic and heterotypic continuity, while soothability and duration of orienting showed significant differential heterotypic continuity. On the level of latent superconstructs, infant positive and negative affectivity accounted for 4.6, 22.3, and 6.0% of the variance in childhood extraversion, effortful control and negative affectivity, respectively. Infant and childhood temperament clustered into profile types named “resilient”, “undercontrolled”, and “overcontrolled” mirroring ipsative continuity. These findings give empirical credence to Rothbart's theory by replicating and extending previous findings in significant ways.     

A longitudinal study of student-teacher relationship quality, difficult temperament, and risky behavior from childhood to early adolescence

This study examines the mediating role of student-teacher relationship quality (conflict and closeness) in grades 4, 5, and 6 on the relation between background characteristics, difficult temperament at age 4½ and risky behavior in 6th grade. The longitudinal sample of participants (N = 1156) was from the NICHD Study of Early Child Care and Youth Development. Structural equation modeling was used to estimate paths from (a) background characteristics to student-teacher relationship quality and risky behavior, (b) temperament to student-teacher relationship quality and risky behavior, and (c) student-teacher relationship quality to risky behavior. Findings indicate that students' family income, gender, receipt of special services, and more difficult temperament were associated with risky behavior. In addition, student-teacher conflict was a mediator. Students with more difficult temperaments were more likely to report risky behavior and to have conflict in their relationships with teachers. More conflict predicted more risky behavior. Closer student-teacher relationships were associated with less risky behavior. Results suggest negative relationships, specifically student-teacher relationships, may increase the risk that certain adolescents will engage in risky behavior.     

Teacher–child relationship,child withdrawal and aggression in the development of peer victimization

The study examined pre-kindergarten teacher–child relationship as a predictor of peer victimization up to first grade, assessed whether this role moderated risks from children's social withdrawal and/or aggression. Participants were 377 Australian children from 12 schools. Parent ratings of victimization in pre-kindergarten, kindergarten and first grade were used, as well as prekindergarten self-ratings of parenting. Teacher-ratings of conflict and closeness, child aggression and social withdrawal were collected in pre-kindergarten. Two-part growth curve analyses conjointly modeled the likelihood of being victimized and severity of victimization. Teacher–child conflict in prekindergarten predicted the likelihood of concurrent and first grade victimization; closeness in prekindergarten was protective of more severe victimization over time. Conflict also moderated the relationship between social withdrawal and growth in severity of victimization. Discussion focuses on elucidating the ‘invisible hand’ of the teacher in peer dynamics, and on interventions for reducing conflict and promoting closeness in the classroom.     

A longitudinal study of temperament continuity through IBQ,TBAQ and CBQ

The aim of this work was to study the continuity of temperament in a Spanish sample (n = 60), covering the developmental stages of infancy, toddlerhood and childhood. Temperamental dimensions showed, with few exceptions, as much homotypic as heterotypic continuity as was to be expected. At the level of latent superconstructs continuity, we found that Anger and Fear followed different developmental paths and showed continuity over all the periods evaluated. Positive Affect/Regulation superconstruct showed continuity from infancy to toddlerhood. From toddlerhood, Positive Affect/Regulation showed continuity with the superconstruct of Effortful Control but not with the superconstruct of Surgency/Extraversion. At an ipsative level, we found two groups of subjects, labeled ‘nonexpressive/controlled’ and ‘noncontrolled/expressive’. Generally, these results confirm the stability of temperament in the periods analyzed and underline the importance of toddlerhood as a transitional period in the maturity of self-regulatory capabilities shown in childhood.     

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.     

Risk-Taking Behavior as a Mediator of the Relationship between Children's Temperament and Injury Liability

The relationship between childhood temperament, risk-taking behavior and injury liability is investigated in a sample of 209 two- to nine-year-old children using parental report. Temperament was found to be significantly related to both risk-taking behavior and the number of injuries sustained; moreover, risk-taking behavior was a significant predictor of injuries. A mediational model was tested and risk-taking behavior was found to mediate the relationship between temperament and injury liability. The implications of these findings are discussed within the context of preventive actions.
