Prenatal origins of temperament: Fetal cardiac development & infant surgency,negative affectivity,and regulation/orienting

Temperament, i.e. individual differences in reactivity and self-regulation, emerges early in infancy; might temperament originate during fetal development? Mixed findings and methodological issues in the literature examining this consideration limit our understanding of the continuity between these fetal indices and infant temperament. The primary aims of the current study were to improve on published studies by (a) using standardized and well-accepted fetal cardiac (actocardiograph) and infant temperament measures (the Infant Behavior Questionnaire—Revised; IBQ-R) (b) expanding fetal assessments to include coupling (the cross correlation of heart rate with movement), and (c) examining a diverse sample to determine if findings of associations between fetal neurobehavior and infant temperament generalize beyond cohorts that are demographically well-resourced and predominantly white. Building on theory and empirical findings, we hypothesized that (1) FHR would be positively associated with Surgency and Negative Affectivity, (2) FHRV would be positively associated with Surgency, and Regulation/Orienting and inversely associated with Negative Affectivity, and (3) fetal coupling would be positively associated with Regulation/Orienting and Surgency and inversely associated with Negative Affectivity. We collected 20 min of fetal data (m gestational age = 34.42 weeks) and mothers completed the IBQ-R (n = 90 women; 60 % non-Caucasian race; 63 % Latina ethnicity). We found that FHR was positively associated with Negative Affectivity but not associated with Surgency (or Regulation/Orienting). FHRV was inversely associated with Surgency but not associated with Negative Affectivity or Regulation/Orienting. Coupling was positively associated with Regulation/Orienting and Surgency but not associated with Negative Affectivity. Our findings, from a more diverse sample and with established measures, provide further evidence that individual differences in reactivity and regulation can be identified in the in-utero period and show theory-based continuity to specific infant temperament constructs.     

The structure and stability of temperament from infancy to toddlerhood: a one-year prospective study

This study investigated the factor structure and longitudinal stability of temperament in a multi-informant (i.e., as reported by mothers and fathers), one-year prospective study from infancy (8-13 months) to toddlerhood (20-25 months). Confirmatory factor analyses (CFAs) replicate and extend earlier studies; in that evidence was found for a three-factor structure for both infant and toddler temperament, consisting of Surgency/Extraversion, Negative Affectivity and Effortful Control. There were, especially in toddlerhood, few differences between mother and father reports in average scores on the three temperament factors, which were in part related to differences in parental involvement between mothers and fathers. In addition, there were few differences between average scores for boys and girls on these temperament factors, with the exception that both mothers and fathers rated girls higher on Effortful Control, and fathers rated boys higher on Extraversion/Surgency, especially in toddlerhood. Finally, results showed that the three factors showed high relative, absolute, and structural stability over a one-year period. The implications of these findings for contemporary temperament research are discussed.     

Differences in infant temperament between Chile and the US

Temperament refers to individual differences in reactivity and self-regulation and is influenced by genetic and experiential variation and maturation. Temperament reflects biologically based individual differences that emerge in early life and remain relatively stable thereafter. Given the growing interest in cultural variation in infant temperament, this study examined the temperament of 12-month-old children in Chile and the US. The aims were to validate a version of the Infant Behavior Questionnaire – Revised – Very Short Form in Spanish for Chile and to compare Chilean and US infants’ temperament. For the first aim, 150 Chilean infants aged 10–15 months were assessed, and 73 US infants aged 10–15 months were examined for the second aim. The children’s parents completed a demographic questionnaire and the IBQ-R-VSF, which measures three dimensions of temperament: Surgency, Negative Affectivity, and Effortful Control. The reliability of each dimension for the Chilean sample was between 0.70 and 0.75, and significant differences between Chilean and US infants emerged. Parents of Chilean infants reported higher levels of Effortful Control, whereas US parents reported that their infants exhibited higher levels of Negative Affectivity. A relationship between parents’ higher educational level and infants’ higher levels of Surgency was found for both countries. No gender or age differences were observed for any of the three temperament dimensions. These results and their implications for cultural studies are discussed.     

Temperament and externalizing behavior: social preference and perceived acceptance as protective factors

The purpose of this study was to explore the role of social preference and perceived acceptance as moderators of the relation between child temperament and externalizing behavior. Participants included 399 children evaluated at pre-kindergarten and kindergarten assessments. Pre-kindergarten children characterized by high temperamental Surgency/Extraversion were more likely to exhibit hyperactivity and aggression in the kindergarten classroom. In addition, kindergarten perceived acceptance and social preference moderated the relation between pre-kindergarten Surgency/Extraversion and kindergarten hyperactivity for girls only. Girls who were characterized by high temperamental Surgency/Extraversion, high perceived acceptance, and low social preference were at risk for higher levels of teacher-reported and peer-nominated hyperactivity. In contrast, accurately high perceived acceptance was a protective factor for high temperamental Surgency/Extraversion. Findings are discussed in terms of risk and protective factors for externalizing behavior.     

The longitudinal associations between temperament and sleep during the first year of life

Temperament and sleep in infants are related but also distinct concepts. The longitudinal effects of temperament on sleep in infancy remain unclear, although this information is potentially important for the prevention and treatment of early sleep problems. We examined how various temperament features influence sleep development during the first year of life in a large birth cohort. This study comprised mother-infant dyads with complete longitudinal data on sleep, temperament and sociodemographic measurements at six and 12 months (N = 1436). We observed that higher infant Negative Affectivity was related to several sleep problems, and that many subscales of Negative Affectivity and Orienting/Regulation predicted worse sleep and deterioration in sleep problems from six to 12 months. Few associations between Surgency and sleep were found. Our findings highlight especially Negative Affectivity as a risk factor for persistent and increasing sleep problems, and also the specific importance of the fine-grained aspects of temperament in predicting infant sleep development.     

Validating the Children's Behavior Questionnaire in Dutch children: psychometric properties and a cross-cultural comparison of factor structures

In this article, we examined the factorial validity of the Dutch translation of the Children's Behavior Questionnaire (CBQ) and the Very Short Form scores. In addition, we conducted cross-cultural comparisons of temperament structure. In total, 353 parents of 6- to 8-year-olds completed the instrument. The original higher order factor structure of the different CBQ forms was generally replicated and represented the three broad dimensions of temperament: Surgency/Extraversion, Negative Affectivity, and Effortful Control. For the Standard Form, results demonstrated a relatively high degree of factor similarity of the Dutch sample with other cultures (e.g., China and Japan). The findings provide evidence for applicability of the CBQ in Western Europe as a promising instrument to comprehensively assess reactive and self-regulative temperamental dimensions in young children.     

East–west,collectivist-individualist: A cross-cultural examination of temperament in toddlers from Chile,Poland, South Korea,and the U.S.*

The present study examined toddler temperament across Chilean, South Korean, Polish, and U.S. samples, providing an opportunity to examine both collectivist-individualist and East–West contrasts. The effect of culture on the three factor and 18 dimension scores provided by the Early Childhood Behavior Questionnaire were investigated. Results provide evidence of cross-cultural differences between the four samples. Chilean toddlers scored significantly higher than U.S., Polish, and South Korean children on the overall factor of Negative Affectivity, as well as higher than the Polish and South Korean samples on the Surgency factor. South Korean toddlers scored significantly higher on the factor of Effortful Control, and two related dimensions, than U.S., Polish, or Chilean samples. Results are discussed in terms of the apparent roles of individualism/collectivism and East–West distinctions in shaping temperament development.     

Measurement of fine-grained aspects of toddler temperament: the early childhood behavior questionnaire

This article describes the development, reliability, and factor structure of a finely differentiated (18 dimensions) parent-report measure of temperament in 1.5- to 3-year-old children, using a cross-sectional sample (N=317) and a longitudinal sample of primary (N=104) and secondary (N=61) caregivers. Adequate internal consistency was demonstrated for all scales and moderate inter-rater reliability was evident for most scales. Longitudinal stability correlations were primarily large over 6- and 12-month spans and moderate to large from 18 to 36 months. Factor analysis revealed a three-factor structure of Surgency/Extraversion, Negative Affectivity, and Effortful Control. In both samples and for both primary and secondary caregivers, older children received higher scores for Attention Focusing, Discomfort, Inhibitory Control, and Positive Anticipation. Primary caregivers rated females higher in Fear, and lower in High-intensity Pleasure, than males; secondary caregivers rated females higher than males in several aspects of Effortful Control.     

Aggregate temperament scores from multiple countries: Associations with aggregate personality traits,cultural dimensions,and allelic frequency

Aggregate temperament scores were calculated across 17 studies for 18 countries. These scores were analyzed in relation to aggregate personality scores, cultural orientation, and allelic distribution reported in prior studies. Cross-culture patterns were largely consistent with those previously reported for personality: countries high on Surgency (SUR) were high on Extraversion, high Negative Affectivity (NEG) was consistent with Neuroticism, and Regulatory Capacity (RC) with Agreeableness. Regarding cultural orientation, aggregate SUR was associated with low Power Distance and Long-Term Orientation; NEG with low Individualism and high Masculinity and Uncertainty Avoidance; and RC with low Power Distance and Masculinity. Higher proportion of MAOA-uVNTR low expression alleles was associated with low SUR and low RC; and A118G G-form allele proportion with low RC.     

Positive mood effects on delay discounting

Delay discounting is the process by which the value of an expected reward decreases as the delay to obtaining that reward increases. Individuals with higher discounting rates tend to prefer smaller immediate rewards over larger delayed rewards. Previous research has indicated that personality can influence an individual's discounting rates, with higher levels of Extraversion predicting a preference for immediate gratification. The current study examined how this relationship would be influenced by situational mood inductions. While main effects were observed for both Extraversion and cognitive ability in the prediction of discounting rates, a significant interaction was also observed between Extraversion and positive affect. Extraverted individuals were more likely to prefer an immediate reward when first put in a positive mood. Extraverts thus appear particularly sensitive to impulsive, incentive-reward-driven behavior by temperament and by situational factors heightening positive affect.     

The Role of Temperament and Personality in Problem Behaviors of Children with ADHD

This study describes temperament, personality, and problem behaviors in children with Attention-Deficit Hyperactivity Disorder (ADHD) aged 6 to 14 years. It targets differences between an ADHD sample (N = 54; 43 boys) and a large community sample (N = 465; 393 boys) in means and variances, psychometric properties, and covariation between traits and internalizing and externalizing problems. Parents rated their children on Buss and Plomin’s and Rothbart’s temperament models, a child-oriented five-factor personality model and also on problem behavior. Relative to the comparison group, children with ADHD presented with a distinct trait profile exhibiting lower means on Effortful Control, Conscientiousness, Benevolence and Emotional Stability, higher means on Emotionality, Activity, and Negative Affect, but similar levels of Surgency, Shyness, and Extraversion. Striking similarities in variances, reliabilities and, in particular, of the covariation between trait and maladjustment variables corroborate the spectrum hypothesis and suggest that comparable processes regulate problem behavior in children with and without ADHD.     

Measuring child temperament: Validation of a 3‐item Temperament Measure and 13‐item Impulsivity Scale

A 3-item Temperament Measure and a 13-item Impulsivity Scale were tested against the 36-item Children's Behaviour Questionnaire (CBQ). Overall, 229 caregivers completed the CBQ and the 3-item Temperament Measure based on the traits of Surgency, Negative Affectivity and Effortful Control as measured by the CBQ. Their children completed the Impulsivity Scale. Psychometrics of the CBQ and the Impulsivity Scale were examined, which were considered good in terms of internal consistency and factorial structure. The three temperament items correlated with the average scores on the corresponding CBQ factors. Furthermore, Surgency was highly related to Impulsivity. Findings provide evidence for the applicability of the Impulsivity and Temperament Measures for research.     

The Children's Behavior Questionnaire very short scale: psychometric properties and development of a one-item temperament scale

Little research has been conducted on the psychometrics of the very short scale (36 items) of the Children's Behavior Questionnaire, and no one-item temperament scale has been tested for use in applied work. In this study, 237 United States caregivers completed a survey to define their child's behavioral patterns (i.e., Surgency, Negative Affectivity Effortful Control) using both scales. Psychometrics of the 36-item Children's Behavior Questionnaire were examined using classical test theory, principal factor analysis, and item response modeling. Classical test theory analysis demonstrated adequate internal consistency and factor analysis confirmed a three-factor structure. Potential improvements to the measure were identified using item response modeling. A one-item (three response categories) temperament scale was validated against the three temperament factors of the 36-item scale. The temperament response categories correlated with the temperament factors of the 36-item scale, as expected. The one-item temperament scale may be applicable for clinical use.     

The development of prudence in the face of varying future rewards

The choice to delay gratification, opting for a greater reward later instead of a smaller reward now, has been used as a measure of preschoolers' ability to make future-oriented decisions. The present studies investigated to what extent these choice tasks reflect children's ability to make choices in favour of their future self. In Experiment 1, preschoolers were presented with choices between a smaller immediate reward of one sticker and larger delayed rewards varying in amount from two to five stickers. Whereas 3-year-olds showed no increased tendency to choose the delayed option as quantity increased from two to five, 4-year-olds' future-oriented choices reflected the value of the delayed reward. In Experiment 2, preschoolers chose between immediate and delayed rewards that were equal in amount and varied between one and four stickers. Three-year-olds reliably chose the immediate reward and showed no differentiation among rewards, whereas 4-year-olds chose in a manner that suggested they were trying to satisfy both immediate and future desires. Together these results support the notion that future-oriented prudence reflects growth in concern for the future self.     

Individual differences in preschool children: temperament or personality?

Individual differences among adults have generally been conceptualized in terms of personality theory and traits. In contrast, individual differences among very young children (birth to kindergarten) have generally been conceptualized in terms of temperament theory and traits. The present study compares and contrasts measures of temperament and personality in a sample of preschool children. Temperament traits were assessed with a well‐established measure (the Rothbart CBQ), and a new preschool rating instrument was used to assess personality traits from the five‐factor framework (M5‐PS). Indeed, a key purpose of this study was to further the development of the M5‐PS. Data were gathered on 122 preschool children who were rated by their teachers. Significant correlations were found between the temperament trait Surgency and the personality trait Extraversion, between the temperament trait Negative Affect and the personality trait Neuroticism, and between the temperament trait Effortful Control and the personality trait Conscientiousness. The overall pattern of correlational data suggests that individual differences in preschool children can be adequately described using the five‐factor theory, and that this framework may effectively subsume traditional theories of temperament. Preliminary support for the reliability and validity of the M5‐PS is offered. Copyright © 2010 John Wiley & Sons, Ltd.     

Type D Personality: A Five-Factor Model Perspective

This study investigated the position of Type D (high Negative Affectivity and high Social Inhibition) within the Five-Factor Model (FFM) of personality. A sample of 155 healthy subjects were administered the Type D Scale and the NEO-FFI, assessing the FFM traits. Subjects also filled out the General Health Questionnaire and the Job Stress Survey. Negative Affectivity was positively correlated with Neuroticism (0.74) and negatively with Conscientiousness ( m 0.38), Agreeableness ( m 0.37), and Extraversion ( m 0.35). Social Inhibition was negatively correlated with Extraversion ( m 0.61) and Conscientiousness ( m 0.40) and positively with Neuroticism (0.50). Type D subjects reported more somatic distress ( p <0.0001), anxiety ( p <0.0001) and depression ( p <0.01) than non-Type D subjects. An alternative one-dimensional representation of the D-traits was suggested, conceptualized as a dimension ranging from neurotic introversion with relatively low conscientiousness to stable extraversion with relatively high conscientiousness. These findings are discussed in the light of the renewed interest in psychology for type versus dimensional representations of individual differences.     

Negative affectivity moderated by preterm birth predicted toddlers’ behavior problems

ObjectiveThe present study aimed to examine the predictive effect of temperament moderated by preterm childbirth on behavioral problems in toddlerhood.MethodThe sample comprised 100 toddlers of 18–36 months of chronological age and their mothers. They were divided into two groups: 50 toddlers born preterm and admitted to the Neonatal Intensive Care Unit (PT group), and 50 toddlers born full-term (FT group) and recruited from day-care centers. Mothers completed questionnaires about toddlers’ temperament and behavior. The Early Childhood Behavior Questionnaire was used to assess temperament, and the Child Behavior Checklist (CBCL 1¹/²–5) to evaluate the total, internalizing, and externalizing behavior problems. Multiple regression analysis was performed to examine the moderation effects of preterm childbirth and temperament factors after controlling for toddlers’ age and socioeconomic level.ResultsThere was a moderation effect between preterm childbirth and temperament. Temperament with more Negative Affectivity, moderated by preterm birth, and less Effortful Control explained the total, internalizing, and externalizing behavior problems.ConclusionThe findings contribute to a better understanding of the impact of preterm childbirth and the dispositional traits of temperament on behavioral problems of toddlers born preterm.     

Individual differences in preschoolers' physiological and verbal responses to videotaped angry interactions

Individual differences in selection of intensity of angry interactions and physiological and self-reported responses to interadult anger were examined in preschoolers (N=34). Children watched two videotaped angry interactions between adults, while their heart rates and skin conductance responses and levels were monitored; then they were interviewed. Before the second argument, children were given the perceived choice of watching an intense or mild angry exchange. Individual differences in responding to the angry interactions were found. Both (a) children with relatively higher externalizing behavior problems and (b) boys who chose to watch intense anger had lower tonic heart rates; 80% of boys with externalizing problems chose to watch intense anger. Further, children who chose to watch intense anger (a) exhibited lower declines in heart rates upon the presentation of the argument, (b) perceived the actors as more angry, and (c) reported lower amounts of distress during the argument than those who chose mild anger.     

A new approach to assessing optimism: the development of a german version of the positive and negative expectancies questionnaire (paneq-g)

This study describes the construction and validation of a German version of the Positive and Negative Expectancies Scale, PANEQ-G, which is based on the original English version of the PANEQ. The German version showed the same factor structure as the original, comprising the three subscales of Negative Affectivity/Pessimism, Positive Affectivity/Optimism, and Fighting Spirit. The reliability data for the new scale were acceptable, and the factor structure was confirmed by means of a confirmatory factor analysis in an independent sample. As expected, concurrent validation uncovered substantial correlations of the three established scales. Negative Affectivity/Pessimism was related to Neuroticism and Positive Affectivity/Optimism was related to Extraversion. Fighting Spirit, the third scale, was related to Self-Efficacy and Conscientiousness. The PANEQ-G provides a reliable and valid instrument that can be used in conjunction with the original PANEQ for cross-cultural studies on Optimism and Pessimism. It also offers a new third component, Fighting Spirit, which can enrich research in this area.
