Temperament and Happiness in Children in India

The relation between temperament and happiness was assessed in a sample of 441 children aged 7–14 years drawn from a population in Northern India. Parents assessed their children’s happiness and rated their children’s temperament using the Emotionality, Activity, and Sociability Temperament Survey (EAS). Children self-reported their own happiness using a single-item measure, the Oxford Happiness Scale Short Form, and the Subjective Happiness Scale. Parents’ temperament ratings conformed to the four factor structure proposed by Buss and Plomin (Temperament: early developing personality traits. Lawrence Erlbaum Associates, Hillsdale, 1984): Emotionality, Activity, Sociability, and Shyness. Temperament accounted for between 4 and 11% of the variance in children’s happiness depending on the measures. Children who were more social and active, and less shy, were happier. This result parallels the well-established relation between happiness and personality in adults and is similar to recent research on happiness and temperament in children; temperament traits akin to extraversion were positively associated with happiness. However, despite that neuroticism and its temperament counterpart are strongly and consistently linked to happiness in adults, the relation between happiness and the temperament trait associated with neuroticism (i.e., Emotionality) was weak. This suggests that the relations between temperament and happiness in children may not completely generalize across cultures.     

Spirituality,Religiousness, and Happiness in Children Aged 8–12 Years

The relation between spirituality and happiness was assessed in 320 children aged 8–12 from public and private (i.e., faith-based) schools. Children rated their own spirituality using the Spiritual Well-Being Questionnaire and 11 items selected and modified from the Brief Multidimensional Measurement of Religiousness/Spirituality which reflected the children’s practices and beliefs. Children’s happiness was assessed using self-reports based on the Oxford Happiness Scale short form, the Subjective Happiness Scale, and a single-item measure. Parents also rated their children’s happiness. Children and parents rated the children’s temperament using the emotionality, activity, and sociability temperament survey. Children’s spirituality, but not their religious practices (e.g., attending church, praying, and meditating), was strongly linked to their happiness. Children who were more spiritual were happier. Spirituality accounted for between 3 and 26% of the unique variance in children’s happiness depending on the measures. Temperament was also a predictor of happiness, but spirituality remained a significant predictor of happiness even after removing the variance associated with temperament. The personal (i.e., meaning and value in one’s own life) and communal (quality and depth of inter-personal relationships) domains of spirituality were particularly good predictors of children’s happiness. These results parallel studies of adult happiness and suggest strategies to enhance happiness in children.     

Spanish adaptation of the EAS Temperament Survey for the assessment of child temperament

Better understanding of child temperament is essential, as it may predict subsequent development of psychopathology. Questionnaires which have been adapted to Spanish population include a rather restricted age range. The Emotionality Sociability and Activity (EAS) Temperament Survey has been widely used in child temperament genetic research. A Spanish version of the scale was administered to a sample of 229 mothers and to their children at 18 and 42 months of age. Its psychometric features were examined. Results showed accuracy indices akin to that obtained in prior studies. Findings suggest a three-factor structure for the assessment of temperament.     

The Emotionality Activity Sociability Temperament Survey: Factor analysis and temporal stability in a longitudinal cohort

We investigated Buss and Plomin’s Emotionality Activity Sociability (EAS) Temperament Survey for Children, used to assess temperament. Temperament is believed to comprise stable traits that change little over time. We examined stability of EAS temperament in the Avon Longitudinal Study of Parents and Children, in which 7429 mothers completed the EAS when their children were 3, 5 and 6 years old. Factor analysis was conducted at each time point, and stability over time was assessed using correlation and mixed effects regression modelling, accounting for differences within and between individuals. A four-factor model provided the best fit, with 19–20 of the 20 items loading onto the dimensions predicted by Buss and Plomin. Test–retest correlations ranged from 0.52–0.64 (3–5 years), 0.59–0.74 (5–6 years) and 0.46–0.58 (3–6 years). Mixed effects regression modelling suggested good stability over time: differences between, rather than within, individuals accounted for between 69% and 82% of the variance. This study demonstrates the stability of temperament over time, a vital pre-requisite to investigating childhood temperament as a predictor of outcomes.     

The contribution of temperament,popularity, and physical appearance to children’s happiness

The relation between the happiness of 9–12 year old children and their temperament, popularity, and physical appearance was examined. Participants included 432 children and their parents and teachers. Happiness in children was assessed using a self-rating scale, parents’ ratings, teachers’ ratings, and the Happiness and Satisfaction Subscale of the Piers-Harris Children’s Self-Concept Scale 2 (Piers-Harris 2) [Piers, E. V., & Herzberg, D. S. (2002). Manual for the Piers-Harris Children’s Self-Concept Scale, 2nd ed. Los Angeles: Western Psychological Services]. Estimates of children’s temperament, popularity, and physical appearance included parents’ ratings, individual items on the Piers-Harris 2, and three domain scales from the Piers-Harris 2: the Freedom From Anxiety Subscale, Popularity Subscale, and Physical Appearance and Attributes Subscale. Children’s happiness was correlated with and predicted by ratings of their temperament, popularity, and appearance. Demographic variables did not account for appreciable variance in children’s happiness. The results parallel the common finding that internal factors (e.g., personality), but not external factors (e.g., demographics), predict adults’ happiness.     

The Role of Emotion in Parent-Child Relationships: Children’s Emotionality,Maternal Meta-Emotion,and Children’s Attachment Security

This study was intended to examine the relationship among children’s emotionality, parental meta-emotion, and parent–child attachment. The sample consisted of 546 5th and 6th grade children and their mothers. The test instruments used in this study were the Emotionality subscale of the EAS Temperament Survey (mothers’ ratings only), the Parental Meta-Emotion Survey (mothers’ ratings only) and the Attachment Security Scale (children’s ratings only). Our results showed that maternal meta-emotion (emotion coaching plus emotion dismissing) was associated with children’s attachment security vis-à-vis their mothers. Mothers who tended to adopt an emotion-coaching philosophy were more likely to achieve secure parent–child attachments, as reported by their children. Children whose mothers tended to adopt an emotion-dismissing philosophy reported lower levels of attachment security. There were no direct or indirect effects of children’s emotionality on their attachment security. Parental meta-emotion, but not children’s emotionality, was significantly associated with children’s attachment security. The results indicate the importance of parenting factors in determining the parent–child relationship. Parental education programs that focus on parental attitudes and practices related to emotion should be advocated.     

Genetic and environmental determinants of temperament: a comparative study based on Polish and German samples

This study of 1555 adult mono‐ and dizygotic twins reared together estimates the heritability of temperament traits in a Polish and a German sample. We test whether the etiology of temperament traits differs between the two cultures and between different temperament traits. We assessed temperament traits with the Formal Characteristics of Behaviour–Temperament Inventory (FCB‐TI), the Pavlovian Temperament Survey (PTS), the Revised Dimensions of Temperament Survey (DOTS‐R), and the Emotionality–Activity–Sociability Temperament Survey (EAS‐TS). Taking error of measurement into account, genetic sources of variance explained about 50% of the variance of temperament traits. We found neither reliable cultural differences nor robust differences in the etiology of the traits. However, the four questionnaires differed systematically with respect to the proportion of genetic and environmental influences on their scales. Copyright © 2002 John Wiley & Sons, Ltd.     

The Contribution of Social Relationships to Children’s Happiness

The association between happiness and social relationships was examined in 9- to 12-year-old children. Participants included 432 children and their parents. Children’s happiness was assessed using self-rating scales, parent’s ratings, and the Happiness and Satisfaction Subscale from the Piers-Harris Children’s Self-Concept Scale, Second Edition (Piers and Herzberg 2002). Children’s social relations were assessed with items from the Piers-Harris scale and questionnaires given to the children and their parents. These items were grouped into two positive (i.e., family and friends) and two negative categories (i.e., negative relations with peers and behaving badly toward others). Variance in children’s happiness was partially accounted for by positive social interactions involving the family (e.g., children agreeing that they are important members of their family) and friends (e.g., parents reporting that their children visit with friends more frequently). Negative social interactions also explained variance in children’s happiness including negative relations with peers (e.g., children agreeing that they feel left out of things) and behaving badly toward others (e.g., children agreeing that they are often mean to other people, and they cause trouble for their family). Demographic variables related to the family (i.e., number of siblings, age of parents, and marital status of parents) were only weakly, or not at all, associated with children’s happiness. The results parallel findings from the literature involving adults and adolescents; social relationships are significant correlates and predictors of happiness.     

Temperament in adults--reliability, stability, and factor structure of the EAS Temperament Survey

We assessed the factor structure and psychometric properties of the Emotionality, Activity, and Sociability (EAS) Temperament Survey (Buss & Plomin, 1984) for adults using a longitudinal sample of adult women. The stability estimates of the EAS instrument were assessed over a period of 3 years. The results indicated an acceptable fit for the basic theoretical EAS model, implying that the scale is functioning satisfactory. However, the results also suggest that the measure could be improved. Across time, latent stability factors explained within-scale covariances. Both latent stability factors and time-specific factors accounted for cross-sectional covariances between subscales. Additional research is warranted to guide the further development of the EAS model.     

How Are Traits Related to Problem Behavior in Preschoolers? Similarities and Contrasts Between Temperament and Personality

The lack of empirical research relating temperament models and personality hinders conceptual integration and holds back research linking childhood traits to problem behavior or maladjustment. This study evaluates, within a sample of 443 preschoolers, the relationships between children’s maladaptation and traits measured by three temperament models (Thomas and Chess, Buss and Plomin, and Rothbart), and a Five-Factor based personality model. Adequate reliabilities and expected factor structures are demonstrated for most scales. A joint principal component analysis combining 28 temperament and 18 personality scales indicates a six-factor model, distinguishing Sociability, Activity, Conscientiousness, Disagreeableness, Emotionality, and Sensitivity. Regression analyses reveal that although single temperament and personality scales explain from 23% to 37% of problem behavior variance, the six components explain from 41% to 49% and provide a clearer differentiation among CBCL-problem scales. This age-specific taxonomy refines and corroborates conclusions based on narrative reviews and furnishes a more balanced view of trait–maladjustment relationships.

Social Development of Preschool Children in Croatia: Contributions of Child Temperament, Maternal Life Satisfaction and Rearing Practices

We conducted the present study to examine the relationship of maternal characteristics (estimated happiness and life satisfaction, and child-rearing practices) and children’s temperament to conduct problems and prosocial behavior of preschool children in Croatia. Participants were mothers of 258 children (mean age 61.62 months), who gave their estimations on the Satisfaction with Life Scale, the Subjective Happiness Scale, the Parental Behaviour Questionnaire, the EAS Temperament Survey and the Strengths and Difficulties Questionnaire. After analyzing correlations between all the variables included in research, we conducted two hierarchical regression analyses with implementation of predictor variables in 4 stages (socio-demographic variables; mothers’ estimated happiness and life satisfaction; child temperament; mothers’ parenting). In the final step of regression significant predictors of preschoolers’ conduct problems were children’s age, temperamental emotionality and activity, and mothers’ punishment and inductive reasoning. When predicting children’s prosocial behavior, significant predictors were mothers’ inductive reasoning and warmth, and children’s age and temperamental shyness.     

Toddlers’ Temperament Profiles: Stability and Relations to Negative and Positive Parenting

This study investigated the type and stability of temperament profiles in toddlers, and relations of profile probability to negative and positive parenting trajectories. Mothers (N = 96) rated their child’s (41 girls and 54 boys) Sociability, Anger Proneness, and Activity Level four times during 1 year. The assessment of parenting included both maternal self-reports and observational measures. Latent profile analysis indicated three child temperament profiles: a well-adjusted ‘typical’ profile, an ‘expressive’ profile with heightened externalizing problems, and a ‘fearful’ profile with heightened internalizing problems. Although toddlers’ profile classifications were highly stable across 1 year, individual differences in (changes in) toddlers’ temperament profile probability occurred. We identified negative and positive parenting as environmental mechanisms that were related to the development of temperament profiles over time. These results support the notion that, in addition to having a genetic base, temperament is subject to maturation and experience over time.     

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.     

The genetics and evolution of the general factor of personality

Three studies tested the hypothesis that a general factor of personality (GFP) underlies diverse individual differences including altruism, the Big Five factors of Openness, Conscientiousness, Extraversion, Agreeableness, and Emotional Stability, and the EAS temperament traits of Emotional Stability, Activity, and Sociability. In Study 1, 214 university students completed 36 personality scales. In Study 2, 322 pairs of monozygotic (MZ) and dizygotic (DZ) twins completed 29 5-point rating scales plus questionnaires. In Study 3, 575 pairs of 2- to 9-year-old Korean twins were rated by their mothers on 25 temperament scales. Factor analyses revealed a hierarchical organization with GFP at the apex and the Big Five and/or EAS temperament scales intermediate. The twin data show GFP has an early age of onset with 50% of the variance attributable to non-additive (dominance) genetic influence and 50% to unique, non-shared environmental influence. We discuss a life history matrix encompassing brain size, maturational speed, and longevity, plus emotional intelligence and the personality disorders, and suggest natural selection acted directionally to endow people with more cooperative and less contentious personalities than their archaic ancestors, or nearest living relatives, the chimpanzees.     

Analyse de la structure factorielle du questionnaire de tempérament EAS (version parents) auprès de deux échantillons d’enfants âgés de deux à cinq ans et de six à neuf ans

IntroductionThe EAS temperament survey (Buss & Plomin, 1984) allows the measurement of four heritable and relatively stable dimensions of temperament, that is, Activity, Emotionality, Sociability and Shyness.ObjectiveA French translation of this tool has been validated with children aged from 6 to 12 years (Gasman et al., 2002), our goal is to extend the validation process to a group of younger children.MethodThe temperament of 350 children aged from 2 to 5 years and of 290 children aged from 6 and 9 years was assessed by the EAS and DOTS-R questionnaires (parental ratings).ResultsMulti-group confirmatory factor analysis allowed to confirm the measurement invariance and the structural invariance of the EAS (four-factor model) on both samples and showed that the scale scores are good approximations of the factor scores. Furthermore, there were no significant sex differences in temperament scores and we found that older children were on average less active and more emotional compared to younger ones. Finally, internal consistency and convergent validity of each scale were fairly satisfying.ConclusionThe EAS (parental ratings) can thus be used from the age of 2 years, facilitating the study of temperament development during childhood.     

Persistent pursuit of need-satisfying goals leads to increased happiness: A 6-month experimental longitudinal study

University-based community members (N = 181) participated in a four-wave, 6-month longitudinal experiment designed to increase treatment participants’ happiness levels. Participants were randomly assigned to set goals either to improve their life circumstances (comparison condition) or to increase their feelings of autonomy, competence, or relatedness in life (treatment conditions). We hypothesized that sustained gains in happiness would be observed only in the three treatment conditions, and that even these gains would last only when there was continuing goal engagement. Results supported these predictions and the sustainable happiness model on which they were based (Lyubomirsky et al. in Rev Gen Psychol 9:111–131, 2005). Furthermore, participants with initial positive attitudes regarding happiness change obtained larger benefits. We conclude that maintained happiness gains are possible, but that they require both “a will and a proper way” (Lyubomirsky et al. in Becoming happier takes both a will and a proper way: two experimental longitudinal interventions to boost well-being, 2009).     

The Formal Characteristics of Behaviour—Temperament Inventory (FCB—TI): Validity studies

A psychometric study has been conducted with the aim of testing the validity of the Formal Characteristics of Behaviour—Temperament Inventory (FCB—TI). FCB—TI has been constructed to measure six temperament traits according to the Regulative Theory of Temperament (RTT): Briskness, Perseverance (referring to the temporal aspect of behavior), Sensory Sensitivity, Emotional Reactivity, Endurance, and Activity (referring to the energetic characteristics of behaviour). These traits have been compared with other temperament as well as personality dimensions. The following measures were used: PTS, EAS—TS, DOTS—R, EPQ—R, SSS—V, 16PF, and NEO-FFI. The study was conducted on samples consisting of over 1500 subjects with satisfactory balanced gender ratio (about 50 per cent), and with a broad range of age (from 15 to 77 years), representing a variety of professions and educational levels. The correlational and factor analytic findings are presented; these show high theoretical validity of the FCB—TI scales, except the Sensory Sensitivity scale. In the discussion some conclusions concerning the revision of the structure of temperament have been suggested.     

The Lexical Stroop Sort (LSS) picture-word task: a computerized task for assessing the relationship between language and executive functioning in school-aged children

The relationship between language development and executive function (EF) in children is not well understood. The Lexical Stroop Sort (LSS) task is a computerized EF task created for the purpose of examining the relationship between school-aged children’s oral language development and EF. To validate this new measure, a diverse sample of school-aged children completed standardized oral language assessments, the LSS task, and the widely used Dimensional Change Card Sort (DCCS; Zelazo, 2006) task. Both EF tasks require children to sort stimuli into categories based on predetermined rules. While the DCCS largely relies on visual stimuli, the LSS employs children’s phonological loop to access their semantic knowledge base. Accuracy and reaction times were recorded for both tasks. Children’s scores on the LSS task were correlated with their scores on the DCCS task, and a similar pattern of relationships emerged between children’s vocabulary and the two EF tasks, thus providing convergent validity for the LSS. However, children’s phonological awareness was associated with their scores on the LSS, but not with those on the DCCS. In addition, a mediation model was used to elucidate the predictive relationship between phonological awareness and children’s performance on the LSS task, with children’s vocabulary fully mediating this relationship. The use of this newly created and validated LSS task with different populations, such as preschoolers and bilinguals, is also discussed.     

Peer Victimization and Aggression: Moderation by Individual Differences in Salivary Cortiol and Alpha-Amylase

This research examined whether variations in salivary measures of the hypothalamic-pituitary-adrenal axis (cortisol) and autonomic nervous system (alpha amylase [sAA]) contribute to individual differences in the association between peer victimization and aggression. Children (N = 132; M age = 9.46 years, SD = 0.33) completed a measure of peer victimization, teachers rated children’s aggression, and children’s saliva was collected prior to, and following, participation in a laboratory-based peer-oriented social challenge task. Children rated their level of frustration at the end of the task. Results revealed that victimization interacted with cortisol and sAA measured in anticipation of the task to predict aggression; the victimization × cortisol contribution to aggression was partly mediated by children’s self-reported frustration level. Victimization also was associated with heightened frustration in girls with high task-related sAA reactivity. Task-related sAA reactivity was associated with heightened aggression, but only for girls. These findings suggest that associations between peer victimization and aggression are moderated by variation in the activity of the major components of the psychobiology of stress; results are discussed in relation to theoretical models of individual differences in biological sensitivity to context.     

Intergenerational Transmission of Parenting Style and Personality: Direct Influence or Mediation?

In order to examine the relationships between parenting styles and personality traits over generations, a cross-sectional questionnaire study was conducted for fathers and mothers of school-age children of grades 5–9. The parenting styles measured by the Parental Bonding Instrument (PBI) and the personality traits measured by the Temperament and Character Inventory (TCI) were correlated within and between the consecutive generations (the grandparents and the parents for the PBI and the parents and the children for the TCI). A series of structural equation modeling showed that (1) while the parenting styles were transmitted directly from the grandparents to the parents, it was partly mediated by the fathers’ Co-operativeness (C) but not so for the mothers, (2) while the personality traits were transmitted directly from the parents to the children, it was only the fathers’ parenting styles that mediated C, and (3) the parents’ parenting styles had independent effects upon the children’s personality traits.
