Sleep and Temperament: Maternal Perceptions of Temperament of Sleep-Disturbed Toddlers

Research findings: In order to assess the relations between sleep problems and temperament in infants, temperament ratings of 63 toddlers who presented with night waking problems were compared to those of 35 non-referred toddlers. An objective method to assess sleep patterns was used to validate the distinct sleep patterns of the two groups prior to the comparison of the temperament scales. Measures included: Toddler Temperament Questionnaire (TTQ) and the child's scales of the Parental Stress Index (PSI). On the TTQ, Night Wakers were rated as having lower sensory thresholds compared to the controls. Night Wakers were also rated as less adaptive than the controls. On the PSI, Night Wakers were rated as more distractible; less reinforcing; less adaptive and more demanding. Practice or policy: The results suggest that sleep disturbances in early childhood are closely associated with negative maternal perceptions of child temperament. It is proposed that early detection and treatment of sleep problems during early childhood may prevent some of the associated negative behavioral consequences.     

Maternal Interactions and Self-Reports Related to Attachment Classifications at 4.5 Years

Building on attachment theory and infancy research, this study examines relations between maternal style and attachment patterns in early childhood. Mothers of children classified as Secure at 4.5 years were rated higher than mothers of Insecure children on positive mood, meshing, enjoyment of child, and providing a relaxed home atmosphere. In a laboratory joint task, they had a higher frequency of monitoring, planning, and affirming and also received higher ratings for providing a sensitive framework. Compared with all other mothers, mothers of Avoidant children monitored less and planned less but reported themselves in a better light on 3 temperament scales as well as a depression scale. Mothers of Ambivalent children rated themselves as the most depressed and anxious and the least satisfied with their marriages. Their interactions at home were characterized by friction. Mothers of Controlling children rated themselves as least irritable and anxious, but in the laboratory they affirmed less, enjoyed the task less, and provided a less sensitive framework than all other mothers.     

Family Conflict and Children's Behavior Problems: The Moderating Role of Child Temperament

Child temperament was examined as a moderator of the link between family conflict and child behavior problems. Temperament assessed in early childhood was used to predict the relation between family conflict and externalizing behavior problems measured during the early elementary school years. For children with difficult temperament, a strong association between subsequent family conflict and behavioral adjustment was predicted; for children with easy or intermediate temperaments, low to moderate associations were predicted. These hypotheses were tested across 3 temperament groups (easy, intermediate, and difficult). Data were collected from 108 children and families participating in the Fullerton Longitudinal Study at ages 3 through 10 years. Consistent with the hypotheses, the data provided support for the moderating role of temperament in predicting the association between family conflict and child externalizing behavior problems. These findings suggest that temperamental difficultness operates as a vulnerability factor with respect to the development of children's behavior problems in families with high conflict.     

Applications of Temperament: A Review of Caregiver-Focused Temperament-Driven Interventions

Research Findings: Temperament, often defined in terms of reactive and regulatory tendencies, has been shown to predict child outcomes over and above other risk factors and represents a critical aspect of social-emotional development. The present article is a systematic review of temperament-based interventions targeting caregivers, wherein the aim is to inform caregivers about temperament in an effort to influence a variety of outcomes, such as goodness of fit, parenting stress, achievement, and behavior problems. In total, 13 randomized and nonrandomized trials were reviewed, with promising outcomes. Temperament-driven interventions have demonstrated the capacity to increase parental knowledge of temperament, reduce behavior problems, improve math and reading achievement, create more positive teacher–child relationships, and reduce numbers of medical visits. Caregivers report satisfaction with and usefulness of the interventions, which suggests promise for future application of temperament-based approaches. Temperament-driven interventions can be leveraged to improve multiple developmental outcomes, especially in early childhood, and are useful for both teachers and parents. Practice or Policy: Implications of temperament-based interventions for early childhood educators are discussed, as are limitations and future directions.     

Infant Care: Evaluation of Pre-Care Differences Hypotheses

189 infants/toddlers and their parents were visited in their homes 2 weeks before starting an out-of-home care arrangement and followed every two weeks until 6 months after care had begun (or its equivalent for parent care groups). At the beginning of the study infant/toddlers ranged in age from 2 to 30 months. In this report, hypotheses examining the role of pre-care family characteristics in determining child care use and later child adjustment were evaluated. Discriminant function analyses reliably separated care type and age of entry groups using pre-care family and infant characteristics as predictors. There were no significant differences in child behavior problems (externalizing and internalizing behavior) as a function of care arrangement type experienced. Mother's pre-care parent stress (PSI parent domain subscale: attachment to child) predicted anxious/withdrawn behavior 6 months later. Aggressive/destructive behavior was related independently to mother's health status and parent stress (PSI parent domain subscale: sense of competence) as measured before out-of- home care was begun. Difficult temperament infants had more behavior problems of all types.     

Minor Illnesses,Temperament, and Toddler Social Functioning

Research Findings: Minor illnesses, such as upper respiratory infections, stomachaches, and fevers, have been associated with children's decreased activity and increased irritability. This multi-method investigation of 110 day care–attending children examined whether experience with recurrent, minor illnesses and negative emotionality worked together to predict young children's social functioning. Minor illness experience was assessed via weekly health screenings conducted by nurses. Toddlers' negative emotionality and social behavior were assessed using mothers' and fathers' reports. The two dimensions of negative emotionality and minor illness experience operated in different ways to predict children's functioning. Toddlers rated as more temperamentally angry displayed less social competence, especially when they also experienced high proportions of minor illness. Temperamentally fearful children exhibited more externalizing problems when they experienced a higher frequency of illness, whereas fearfulness was not associated with externalizing problems for children who were not frequently ill. Practice or Policy: Children's frequent experience with minor illnesses combined with negative emotionality appears to place toddlers at a heightened risk for exhibiting behavior problems. These findings have implications for child and family well-being as well as interactions with child care providers and peers within child care settings. Interventions could be developed to target “at risk” children.     

A semantic differential investigation of children's attitudes toward three stigmatized groups

To test the assumption that negative attitudes toward various stigmatized groups are learned in early childhood, four scales of the semantic differential were employed to assess children's attitudes toward four groups (normals, crippled, retarded, and mentally ill) for both male and female third and sixth graders. The mentally ill were rated most negatively on both the Evaluation Scale and the Understandability Scale, but were rated comparable to normal people on Activity and Potency. Both the retarded and the crippled were rated less positively than normals on the Evaluation Scale, but not as negatively as the mentally ill. The retarded and the crippled were rated less Active and Potent than both normals and the mentally ill. No differences were found between the third and sixth graders on attitudes toward the three stigmatized groups. Implications for the “social labeling” theory of mental disorders are discussed.     

Infant Care: Evaluation of Pre-Care Differences Hypotheses

At the beginning of the study infant/toddlers ranged in age from 2 to 30 months. In this report, hypotheses examining the role of pre-care family characteristics in determining child care use and later child adjustment were evaluated.

Aggressive/destructive behavior was related independently to mother's health status and parent stress (PSI parent domain subscale: sense of competence) as measured before out-of- home care was begun. Difficult temperament infants had more behavior problems of all types.     

Can you teach me not to be angry? Relations between temperament and the emotion regulation strategy distraction in 2-year-olds

Little is known about toddlers’ acquisition of specific emotion regulation (ER) strategies, and how early ER is shaped by temperament. This study investigated if 24-month-old German toddlers, predominantly from families with high levels of parental education (N = 96, n = 49 male), learned the ER strategy distraction through observational learning, and its interaction with temperament. Increased use of distraction correlated with reduced negative affect. Use of distraction increased through observational learning. Highly active toddlers tended to use active playing activities to distract themselves in a frustrating situation, whereas toddlers with a less active temperament used calmer activities. Toddlers’ learning to apply distraction through observational learning was independent of a match between their own temperament and the model's actions.     

Investigations of Temperament at Three to Seven Years: The Children''s Behavior Questionnaire

This article reviews evidence on the reliability and validity of the Children's Behavior Questionnaire (CBQ), and presents CBQ data on the structure of temperament in childhood. The CBQ is a caregiver report measure designed to provide a detailed assessment of temperament in children 3 to 7 years of age. Individual differences are assessed on 15 primary temperament characteristics: Positive Anticipation, Smiling/Laughter, High Intensity Pleasure, Activity Level, Impulsivity, Shyness, Discomfort, Fear, Anger/Frustration, Sadness, Soothability, Inhibitory Control, Attentional Focusing, Low Intensity Pleasure, and Perceptual Sensitivity. Factor analyses of CBQ scales reliably recover a three-factor solution indicating three broad dimensions of temperament: Extraversion/Surgency, Negative Affectivity, and Effortful Control. This three-factor solution also appears to be reliably recovered in ratings of children in other cultures (e.g., China and Japan). Evidence for convergent validity derives from confirmation of hypothesized relations between temperament and socialization-relevant traits. In addition, parental agreement on CBQ ratings is substantial. The CBQ scales demonstrate adequate internal consistency, and may be used in studies requiring a highly differentiated yet integrated measure of temperament for children in this age range.     

Children's Temperament, Mothers' Discipline, and Security of Attachment: Multiple Pathways to Emerging Internalization

This study examined relations of temperamental fearfulness/anxiety proneness, attachment security, and maternal discipline with emerging internalization in 103 26–41-month-old toddlers. It was a further test of the model that proposed that child temperament (1) is an important underpinning of early internalization and (2) moderates the influence of socialization. All constructs were measured using multiple behavioral observations in several contexts at home and laboratory and parental reports. Fearfulness/anxiety was associated with several measures of internalization. There was also strong evidence of diverse pathways to internalization for children with different temperaments. For the relatively fearful/anxious children, maternal gentle discipline deemphasizing power, thus presumably resulting in an optimal, moderate level of anxious arousal, predicted internalization. For the relatively fearless children, however, security of attachment was associated with internalization. The findings are discussed within a framework proposing alternative pathways to internalization—one capitalizing on fear/anxiety and one building on positive, cooperative interpersonal set between the mother and child—with different pathways effective for children differing in temperament.     

Longitudinal and Concurrent Relations among Temperament, Ability Estimation, and Injury Proneness

This study examined longitudinal and concurrent relations between temperament, ability estimation, and injury proneness. Longitudinal assessments of Inhibitory Control were collected through a behavioral battery at toddler (33 months) and preschool ages (46 months). Parent-reported measures of Inhibitory Control and Extraversion also were obtained at those ages. At school age (76 months), children participated in a set of tasks to assess overestimation and underestimation of physical abilities. Parents provided reports of children's temperament and injury history at school age. Results showed that children who were high on Extraversion and low on Inhibitory Control as toddlers and preschoolers tended to overestimate their physical abilities and to have more unintentional injuries at age 6. Children low on Extraversion and high on Inhibitory Control tended to underestimate their physical abilities. Implications for injury prevention are discussed.     

At-risk toddlers and their mothers: the special case of physical handicap

Previous studies of school-aged children with physical handicaps indicate passivity, inhibition, and deficits in cognitive-linguistic functioning, sometimes interpreted as consequent to parent-child problems. The present study examined the functioning of toddlers with physical anomalies (but without CNS damage) in comparison to premature toddlers (who share deviant early experience but not deviant physical appearance) and to normal toddlers. 14 mother-child pairs in each group were videotaped at 9, 12, 18, and 24 months in a variety of semistructured situations. Both premature and handicapped toddlers performed more poorly in measures of social initiative, focused play, language production, and 2-year IQ. In addition, handicapped toddlers manifested increased distractibility, decreased compliance, and reluctance to separate from their mothers. Mothers of both prematures and handicapped toddlers were more initiating and less responsive than controls, while mothers of handicapped children were also more likely to both encourage and ignore their toddlers. Patterns previously reported for older children are therefore found here with toddlers. Maternal patterns are interpreted as supporting Bell's model of compensatory "lower-limit" effects.     

Temperament and Self-soothing Behavior in Children: Object Attachment, Thumbsucking, and Pacifier Use

Research Findings. Mothers of 4-, 6-, and 8-year-olds completed two questionnaires: (1) the Object Attachment Questionnaire, which was designed to provide information on children's attachments to soft objects, thumbsucking habits, and pacifier use, and (2) Rothbart's Children's Behavior Questionnaire (CBQ), which rated children on sixteen temperament dimensions. Discriminant function analysis showed that the best predictors for distinguishing between children who had never had an attachment to a soft object and children who had were: low intensity pleasure, impulsivity, approach/anticipation, attentional focusing, and sad- ness. Children with soft object attachments were rated higher (i.e. showed more) on all of these dimensions. None of the temperament dimensions distinguished between children who rarely sucked their thumbs and those who frequently did so, while children who had used a pacifier scored higher on two dimensions (activity level and approach/anticipation) than children who had not used a pacifier even though one was available. Results support the hypothesis that individual differences in temperament are associated with the development of attachment to objects. Practice. Children with attachments to soft objects and thumbs were not generally insecure or difficult to manage. The pattern of temperament differences, however, suggests strengths that teachers might make use of in the classroom as well as difficulties that might require staff intervention.     

Down Syndrome Temperament: The Stereotype at Middle Childhood and Adolescence

MOTHERS AND TEACHERS of 94 children (53 boys) with Down syndrome, between 8 and 14 years of age, rated the children on a temperament scale and provided an overall impression as to whether the child was difficult in comparison with other children. Maternal ratings on the Middle Childhood Questionnaire showed significant differences from standardization scores. Children with Down syndrome were given ratings as less active, more predictable, of more positive mood, less persistent, and more distractible. Some of these dimensions favour the amiable personality stereotype for the syndrome but low persistence was associated with maternal impressions of difficulty. There was little agreement between mothers and teachers regarding the individual children who were rated as being significantly easier or more difficult than other children. Results with a subgroup (n = 32) showed that externalizing behaviours were significantly related to both mother and teacher impressions of difficulty and that mothers also found intense, active, distractible behaviour difficult.     

Temperament and Craniofacial Variation in the First Two Years

High levels of circulating glucocorticoids in fetal animals are associated with inhibited development of the lateral processes of the maxilla, or upper jaw, as these bones grow toward midline union early in gestation. This inhibition can prevent fusion and lead to the formation of cleft palate. Mouse strains are differentially susceptible to this effect. These strains also differ in behavioral and physiological characteristics that are analogous to those we have observed in 2 temperamental groups of children, analogies that prompted the current study. Infant temperament was assessed using behavioral observation at 4 months, and the ratio of upper facial width (bizygomatic breadth across the cheekbones) to height of the head and face was measured at 14 and 21 months. High reactive 4-month-old infants, who are predisposed to becoming timid, inhibited toddlers, had smaller bizygomatic ratios (narrower faces) at both 14 and 21 months compared to their low reactive peers, who are predisposed to becoming outgoing, uninhibited children. Differences in facial width were modest though significant and not attributable to overall stature.     

Spanking and subsequent behavioral problems in toddlers: A propensity score-matched,prospective study in Japan

Harsh or frequent spanking in early childhood is an established risk factor for later childhood behavioral problems as well as mental disorder in adulthood in Western societies. However, few studies have been conducted in Asian populations, where corporal punishment is relatively accepted. Moreover, the impacts of occasional spanking on subsequent behavioral problems remain uncertain. This study sought to investigate prospectively the association between the frequency of spanking of toddlers and later behavioral problems in Japanese children using national birth cohort data. We used data from the Longitudinal Survey of Newborns in the 21st Century, a population-based birth cohort data set collected by the Japanese Ministry of Health, Labour, and Welfare (N = 29,182). Frequency of spanking (“never”, “sometimes” and “always”) and child behavioral problems were assessed via a caregiver questionnaire when the child was 3.5 years old and again at 5.5 years. Propensity score matching was used to examine the association between frequency of spanking and child behavioral problems, adjusting for parental socioeconomic status, child temperament and parenting behaviors. Compared to children who were never spanked, occasional spanking (“sometimes”) showed a higher number of behavioral problems (on a 6-point scale) (coefficient: 0.11, 95% CI: 0.07–0.15), and frequent spanking (“always”) showed an even larger number of behavioral problems compared with “sometimes” (coefficient: 0.08, 95% CI:0.01–0.16). Spanking of any self-reported frequency was associated with an increased risk for later behavioral problems in children.     

Early non-parental care and toddler behaviour problems: Links with temperamental negative affectivity and inhibitory control

This longitudinal study examined the link between multiple aspects of early non-parental care and internalizing and externalizing behaviour at 30 months of age. We also examined whether this link was mediated by children's inhibitory control and moderated by early temperamental negative affectivity. Participants were 193 mothers and their infants (91 girls; 79 firstborn). Negative affectivity was measured with a temperament questionnaire at 3 months of age. Information on non-parental care (i.e. centre-based care, number of hours, number of concurrent arrangements, long-term instability of care and age of entry) was obtained through monthly maternal interviews across the first year of life. At 30 months of age, toddlers’ inhibitory control was measured with observational tasks, and behaviour problem questionnaires were completed by the mothers and the caregivers. The mediation model was not supported. Greater observed inhibitory control, however, was related to less caregiver-reported internalizing and externalizing behaviour. Furthermore, negative affectivity moderated the effect of early non-parental care on behaviour problems. Non-parental care was unrelated to behaviour problems in toddlers who displayed low or mean levels of negative affectivity as infants. For infants high in negativity, however, centre-based care was associated with higher mother-rated internalizing and externalizing problems. In sum, the link between aspects of non-parental care during the first year of life and toddlers’ behaviour problems was not mediated through inhibitory control. Instead, inhibitory control and non-parental care, in conjunction with negative affectivity, appear to be two independent predictors of toddlers’ internalizing and externalizing behaviour.     

Sleep Tight,Act Right: Negative Affect,Sleep and Behavior Problems During Early Childhood

Temperamental negative affect and insufficient sleep have been independently associated with behavior problems during early childhood. However, it is unknown whether these factors interact to contribute to behavioral difficulties in young children. The current study examined the interactions between temperamental negative affect and both sleep onset time and sleep midpoint, assessed by actigraphy, in predicting externalizing and internalizing behaviors in a sample of 117 children (34–69 months of age). Children with high temperamental negative affect and either later sleep onset time or later sleep midpoint were more likely to exhibit externalizing and internalizing behaviors. These results emphasize the association between temperamental negative affect and behavioral difficulties, particularly for children with insufficient sleep.     

Preschool Temperament Assessment: A Quantitative Assessment of the Validity of Behavioral Style Questionnaire Data

Research Findings: Child temperament is an important construct, but its measurement has been marked by a number of weaknesses that have diminished the frequency with which it is assessed in practice. We address this problem by presenting the results of a quantitative construct validation study. We calculated validity indices by hypothesizing the magnitude of relationships between Behavioral Style Questionnaire (BSQ) subscales and criterion measures assessing student–teacher relationships, student characteristics related to teaching stress, and peer play interactions. We tested these hypotheses against the actual correlations observed in a sample of 44 children 40 to 68 months of age. These analyses indicated strong support for 4 of the BSQ subscales (Activity, Rhythmicity, Approach, and Adaptability) and moderate support for 1 subscale (Mood). However, new item generation and testing is recommended for 3 subscales (Intensity, Persistence, and Threshold), along with further construct definition work for the final subscale (Distractibility). Practice or Policy: These findings are particularly relevant for early childhood educators who wish to assess temperament yet are uncertain of the issues involved in its measurement. Results derived from the BSQ, viewed in context, can increase practitioners’ understandings of children's individual characteristics and guide the development of interventions to promote optimal early educational experiences for children.
