Cross-cultural temperamental differences in infants, children, and adults in the United States of America and Finland

How do fathers' educational level contribute to children's school problems? Overparenting and children's gender and surgency in a moderated mediation model

This study aims to investigate (a) the mediating role of overparenting between father's educational level and children's school problems, and (b) the joint moderating role of children's gender and surgency in the indirect relationship between father's educational level and school problems. Participants were 203 school children, 96 boys (47.3%) and 107 girls (52.7%), aged 7-8 years (M = 92.42 months, SD = 3.52). Fathers reported their educational level, age and employment status and their children's gender and number of siblings, as well as their overparenting behaviors by Anticipatory Problem Solving (APS) scale. Teachers informed children's school problems by the Behavior Assessment System for Children (BASC T-2). Parents together informed their children's surgency levels by a subscale of Children's Behavior Questionnaire (CBQ). Results showed that, in girls, the father's educational level was negatively related to the child's school problems via overparenting behaviors, controlling the number of siblings and father's age and employment status. However, among boys, fathers' overparenting protect their shy sons from the risk of a low educational level for school problems. These findings highlight the relevance of considering the gender and surgency to a better understanding of the effects of contextual factors on children's outcomes.

Math anxiety and math motivation in online learning during stress: The role of fearful and avoidance temperament and implications for STEM education

Students' math motivation can predict engagement, achievement, and career interest in science, technology, engineering, and mathematics (STEM). However, it is not well understood how personality traits and math anxiety may be linked to different types or qualities of math motivation, particularly during high-stress times such as the COVID-19 pandemic. In this study, we examined how fearful or avoidant temperaments contribute to math anxiety and math motivations for college students during the COVID-19 pandemic. Ninety-six undergraduate students from a large public university were assessed on temperamental fear, math anxiety, and math motivation in an online math course. Results showed that higher levels of temperamental fear are directly linked to higher levels of math anxiety. In addition, temperamental fear is indirectly linked to higher levels of autonomous motivation (i.e., intrinsic motivation and identified regulation) and lower levels of controlled motivation (i.e., external regulation) through math anxiety. Results have implications for helping students at high risk for both high math anxiety and for low motivation to engage in math learning.

Modulation of dog-owner relationship and dog social and cognitive behavior by owner temperament and dog breed group

As companion dogs spend most of their lives with humans, the human-dog relationship and owner temperament may affect the dog behavior. In this study (n = 440), we investigated the relationship between the dog owner temperament (ATQ-R), owner-perceived dog-owner relationship (MDORS) and the dog behavior in three behavioral tests: the object-choice test, the unsolvable task, and the cylinder test. Dog owner temperament influenced the dog-owner relationship. Owners with high negative affectivity showed higher emotional closeness and perceived costs of their dog, whereas owners with high effortful control showed lower emotional closeness and perceived costs. Higher dog activity during the behavioral tests was also connected with owner-perceived lower emotional closeness. Furthermore, dog breed group modulated the connection between the owner temperament and dog behavior. Owner's high negative affectivity correlated with herding dogs' lower scores in the object choice test, while the behavior of primitive type dogs was unaffected by the owner temperament. Our results confirm that human characteristics are associated with the owner-reported dog-owner relationship, and owner temperament may have a modulatory effect on the dog social and cognitive behavior depending on the dog breed group, which should be investigated further.

Validation of the Arabic version of the 35-item TEMPS-M in a community sample of adults

BACKGROUND

To our knowledge, no brief version of the Temperament Evaluation in Memphis Pisa and San Diego (TEMPS-M) is available so far in the Arabic language, which might have resulted in limited research in this field from Arab countries. We aimed through this study to validate the 35-item TEMPS-M into the Arabic language in a sample of non-clinical Lebanese adults.

METHODS

We used an online cross-sectional survey targeting non-clinical Lebanese adults from the general population. A confirmatory factor analysis was conducted to test the factorial structure of the TEMPS-M.

RESULTS

All five temperament subscales achieved good/very good internal consistencies in the present study (depressive: α = 0.78, cyclothymic: α = 0.86, hyperthymic: α = 0.83, irritable: α = 0.87, and anxious: α = 0.87). The five-factor solution of the TEMPS-M displayed a good CFI of 0.94, TLI of .94 and a GFI of .95, but a poor RMSEA of .10 [90% CI .10, .11]. The five affective temperaments showed positive correlations with personality dysfunction domains, thus attesting for convergent validity. In addition, positive correlations between all affective temperament dimensions and anxiety/depression scores were found. We also tested for gender invariance, and found that configural, metric, and scalar invariance were supported across gender.

CONCLUSION

Our data suggest that the psychometric properties of the Arabic TEMPS-M are good. Making this scale available in Arabic will hopefully encourage Arab researchers to investigate this under-explored topic in their countries, and advance knowledge on how culture impacts the prevalence, development and course of temperament.

Relations between bedtime parenting behaviors and temperament across 14 cultures

Objectives

The present study examined parental sleep-supporting practices during toddlerhood in relation to temperament across 14 cultures. We hypothesized that passive sleep-supporting techniques (e.g., talking, cuddling), but not active techniques (e.g., walking, doing an activity together), would be associated with less challenging temperament profiles: higher Surgency (SUR) and Effortful Control (EC) and lower Negative Emotionality (NE), with fine-grained dimensions exhibiting relationships consistent with their overarching factors (e.g., parallel passive sleep-supporting approach effects for dimensions of NE).

Methods

Caregivers (N = 841) across 14 cultures (M = 61 families per site) reported toddler (between 17 and 40 months of age; 52% male) temperament and sleep-supporting activities. Utilizing linear multilevel regression models and group-mean centering procedures, we assessed the role of between- and within-cultural variance in sleep-supporting practices in relation to temperament.

Results

Both within-and between-culture differences in passive sleep-supporting techniques were associated with temperament attributes, (e.g., lower NE at the between-culture level; higher within-culture EC). For active techniques only within-culture effects were significant (e.g., demonstrating a positive association with NE). Adding sleep-supporting behaviors to the regression models accounted for significantly more between-culture temperament variance than child age and gender alone.

Conclusion

Hypotheses were largely supported. Findings suggest parental sleep practices could be potential targets for interventions to mitigate risk posed by challenging temperament profiles (e.g., reducing active techniques that are associated with greater distress proneness and NE).

The Pandemial babies: effects of maternal stress on temperament of babies gestated and born during the pandemic

The COVID-19 pandemic may configure an adverse prenatal context for early development. The aim of this study was to analyze the effects of pandemic-related negative experiences, prenatal anxiety and depression on the temperament of six-month-old babies. The sample consisted of 105 mother-child dyads. A longitudinal evaluation was carried out using pre- and postnatal online surveys. Mothers completed the State-Trait Anxiety Inventory, the Beck Depression Inventory - II, the Pandemic Impact Questionnaire and the Infant Behavior Questionnaire Revised. Serial mediation models were tested, in which the pandemic-related negative experiences constituted the independent variable, the prenatal anxiety and depression were the mediators, and the children's temperament dimensions were the dependent variables. Pandemic-related negative experiences were indirectly associated with the offspring's negative affect and surgency through anxious symptomatology, which acted as a mediating variable. This was the first study to identify the effects of the COVID-19 pandemic on temperament. Such an adverse context implies risks for child development. Public health policies aiming to evaluate socioemotional variables during early childhood become necessary to allow on-time interventions for lessening these risks.

Temperaments and orthorexia nervosa: a cross-cultural study between Germany and Lebanon

The aim of this study was to explore the association between affective temperaments and orthorexic eating and whether temperament may explain cross-cultural differences in this behavior while considering the two dimensions of orthorexic eating, healthy (HeOr) and nervosa (OrNe). To accomplish this, 337 and 389 individuals were recruited in Lebanon and Germany, respectively. The brief version of the Temperament Evaluation of Memphis, Pisa, Paris and San Diego explored depressive, hyperthymic, cyclothymic, anxious and irritable temperaments, and the Teruel Orthorexia scale explored orthorexic eating. HeOr appeared comparable between countries but OrNe was higher in Lebanon. In terms of affective temperaments, the higher the depressive, cyclothymic, irritable, and anxious temperaments, the higher were the levels of OrNe. Only the hyperthymic temperament scale was positively associated with HeOr. Three-step regression analysis indicated only gender as a unique predictor for HeOr. By contrast, gender, depressive, hyperthymic, and anxious temperament as well as the two-way interactions country*depressive temperament and country*hyperthymic temperament were significant predictors of OrNe. The positive association between OrNe and depressive temperament was only found for the German sample while the negative association between hyperthymic temperament and OrNe was somewhat stronger in the Lebanese sample. Overall, a higher healthy interest in diet was linked to the hyperthymic temperament. Findings emphasized the role of temperaments in pathological orthorexic eating in general as well as in explaining cross-cultural differences in these behaviors. The assessment of temperaments could help to fit treatments for eating pathologies to individuals from different cultures, focusing interventions more on these aspects.

Caregiver-child proximity as a dimension of early experience

Human infancy and early childhood is both a time of heightened brain plasticity and responsivity to the environment as well as a developmental period of dependency on caregivers for survival, nurturance, and stimulation. Across primate species and human evolutionary history, close contact between infants and caregivers is species-expected. As children develop, caregiver-child proximity patterns change as children become more autonomous. In addition to developmental changes, there is variation in caregiver-child proximity across cultures and families, with potential implications for child functioning. We propose that caregiver-child proximity is an important dimension for understanding early environments, given that interactions between children and their caregivers are a primary source of experience-dependent learning. We review approaches for operationalizing this construct (e.g., touch, physical distance) and highlight studies that illustrate how caregiver-child proximity can be measured. Drawing on the concepts proposed in dimensional models of adversity, we consider how caregiver-child proximity may contribute to our understanding of children's early experiences. Finally, we discuss future directions in caregiver-child proximity research with the goal of understanding the link between early experiences and child adaptive and maladaptive functioning.

Using machine learning to understand age and gender classification based on infant temperament

Age and gender differences are prominent in the temperament literature, with the former particularly salient in infancy and the latter noted as early as the first year of life. This study represents a meta-analysis utilizing Infant Behavior Questionnaire-Revised (IBQ-R) data collected across multiple laboratories (N = 4438) to overcome limitations of smaller samples in elucidating links among temperament, age, and gender in early childhood. Algorithmic modeling techniques were leveraged to discern the extent to which the 14 IBQ-R subscale scores accurately classified participating children as boys (n = 2,298) and girls (n = 2,093), and into three age groups: youngest (< 24 weeks; n = 1,102), mid-range (24 to 48 weeks; n = 2,557), and oldest (> 48 weeks; n = 779). Additionally, simultaneous classification into age and gender categories was performed, providing an opportunity to consider the extent to which gender differences in temperament are informed by infant age. Results indicated that overall age group classification was more accurate than child gender models, suggesting that age-related changes are more salient than gender differences in early childhood with respect to temperament attributes. However, gender-based classification was superior in the oldest age group, suggesting temperament differences between boys and girls are accentuated with development. Fear emerged as the subscale contributing to accurate classifications most notably overall. This study leads infancy research and meta-analytic investigations more broadly in a new direction as a methodological demonstration, and also provides most optimal comparative data for the IBQ-R based on the largest and most representative dataset to date.

Temperament is Linked to Avoidant Responses to Stuttering Anticipation

PURPOSE

The purpose of the present study was to examine the degree to which certain temperament constructs predict individual differences in three types of behavioral responses to anticipation among children and adults who stutter (CWS and AWS, respectively): avoidance, physical change, and approach.

METHODS

Participants included 64 CWS (9- to 17-years-old) and 54 AWS (18- to 50-years-old) who completed an online survey package including a temperament questionnaire (Early Adolescent Temperament Questionnaire-Revised for the CWS; Adult Temperament Questionnaire for the AWS) and the Stuttering Anticipation Scale. The data were analyzed separately for CWS and AWS using multivariate multiple regressions to assess how each temperament construct predicted avoidance, physical change, and approach responses to anticipation.

RESULTS

CWS who reported higher levels of shyness were more likely to engage in avoidant behavioral responses when they anticipate an upcoming moment of stuttering. AWS who reported higher levels of orienting sensitivity were more likely to engage in avoidant behavioral responses when they anticipate an upcoming moment of stuttering. No temperament constructs predicted physical change or approach responses to anticipation among either age group.

CONCLUSION

Specific aspects of temperament appear to be linked to the degree that CWS and AWS engage in avoidant behavioral responses to stuttering anticipation. These findings support the continued study of how individual differences impact the internal experience and outward manifestation of stuttering behaviors.

Cultural contributors to negative emotionality: A multilevel analysis from the Joint Effort Toddler Temperament Consortium

This study advances the cross-cultural temperament literature by comparing temperament ratings of toddlers from 14 nations. Multilevel modeling (MLM) procedures were utilized to regress negative emotionality (NE) and component subscales on Hofstede’s cultural value dimensions while controlling for age and gender. More individualistic values were associated with lower NE, and component discomfort, fear, motor activity, perceptual sensitivity, and soothability scales. The discomfort subscale was negatively associated with power distance and positively associated with masculine cultural values. Higher ratings of shyness were related to a more long-term cultural orientation. Results illustrate the feasibility of an MLM approach to cross-cultural research and provide a new perspective on the intersection of culture and temperament development. Limitations and future implications are discussed.

Is an irritable ADHD profile traceable using personality dimensions? Replicability, stability, and predictive value over time of data-driven profiles

Pediatric attention deficit/hyperactivity disorder (ADHD) is a heterogeneous condition. In particular, children with ADHD display varying profiles of dispositional traits, as assessed through temperament and personality questionnaires. Previous data-driven community detection analyses based on temperament dimensions identified an irritable profile of patients with ADHD, uniquely characterized by elevated emotional dysregulation symptoms. Belonging to this profile increased the risk of developing comorbid disorders. Here, we investigated whether we could replicate this profile in a sample of 178 children with ADHD, using community detection based on personality dimensions. Stability of the identified profiles, of individual classifications, and clinical prediction were longitudinally assessed over a 1-year interval. Three personality profiles were detected: The first two profiles had high levels of neuroticism, with the first displaying higher ADHD severity and lower openness to experience (profile 1; N = 38), and the second lower agreeableness (profile 2; N = 73). The third profile displayed scores closer to the normative range on all five factors (profile 3; N = 67). The identified profiles did only partially replicate the temperament-based profiles previously reported, as higher levels of neuroticism were found in two of the three detected profiles. Nonetheless, despite changes in individual classifications, the profiles themselves were highly stable over time and of clinical predictive value. Whereas children belonging to profiles 1 and 2 benefited from starting medication, children in profile 3 did not. Hence, belonging to an emotionally dysregulated profile at baseline predicted the effect of medication at follow-up over and above initial ADHD symptom severity. This finding suggests that personality profiles could play a role in predicting treatment response in ADHD.

The development of temperament and maternal perception of child: A cross-cultural examination in the United States and Japan

Previous research shows cross-cultural differences in adult personality and child temperament, yet the developmental origin of these cultural differences remains unclear. To understand a potential role of socialization grounded in cultural values, this study investigated culturally specific maternal perceptions of child and children's development of temperament in the U.S. and Japan. Maternal perception of child was assessed via maternal interview in the U.S. (n = 42) and Japan (n = 40). Six months after the interview, child's temperament was assessed. Cross-cultural differences in maternal perception of child and child's temperament, and the relation between the two were analyzed. US-American infants scored higher on the surgency/extraversion trait than Japanese infants, whereas Japanese infants scored higher on the negative affectivity/neuroticism trait than US-American infants. US-American mothers used more positive evaluation and private/autonomy descriptions of their infants, whereas Japanese mothers used more negative evaluation and context-specific descriptions of their infants by making references to other people, time, or location. Child's negative affectivity trait was closely related to maternal perception of child's social/context characteristics and negative evaluations. The findings provide support for the socio-cultural framework of temperament development and suggest an important consideration of cultural factors when designing educational and parenting programs.

The Infant Behavior Questionnaire - Revised: psychometric properties at 2 weeks, 3, 6 and 12 months of life

BACKGROUND

Temperament characteristics are key elements for infants' development. The Infant Behavior Questionnaire - Revised (IBQ-R) is one of the most used measures to assess temperament in infants aged between 3 and 12 months. Its reliability and factor structure have not yet been examined in infants younger than 3 months.

AIMS

To analyze the reliability of the IBQ-R at 2 weeks and the IBQ-R factor structure from 2 weeks to 12 months of life.

METHOD

A longitudinal repeated measures design was used. Three hundred mothers completed the IBQ-R when their infants were 2 weeks, and 3, 6 and 12 months.

RESULTS

At 2 weeks the proportion of "non-applicable" responses was higher in duration of orienting, high intensity pleasure, approach and smiling and laughter scales. The Cronbach's alpha for the IBQ-R dimensions ranged between 0.62 and 0.63 and the McDonald's omega ranged between 0.67 and 0.80, all dimensions exhibited a mean-scale correlation above 0.15, and more than half of the scales revealed a scale-dimension correlation higher than 0.30. The same factor structure was found at 2 weeks, and at 3, 6, and 12 months: surgency/extraversion, p < 0.001, negative affectivity, p < 0.001, and orienting regulation, p = 0.007.

CONCLUSIONS

The IBQ-R may be applied in the first weeks of life and its factor structure remains stable when applied across different ages throughout infancy.

Neuropsychological Functioning and Temperament Traits in a Czech Sample of Children and Adolescents at Familial Risk of Bipolar Disorder

Background: Although a positive family history is the strongest predictor for bipolar disorder (BD), most offspring of BD parents (BO) will not develop the disorder. Identification of vulnerability markers for BD is essential for specific individual risk estimation. Impairments in cognitive functioning and the presence of specific temperament traits are considered promising candidates. Methods: Sixty-three BO (48% female; 11.8 ± 3.3 years) and 54 control offspring (CO; 44% female; 12.3 ± 3.2 years) comparable in sex (p = 0.4) and age (p = 0.4) were enrolled. Detection of current sub/threshold mood symptoms by the Kiddie Schedule for Affective Disorders and Schizophrenia and General Behavior Inventory was applied to separate BO into ultrahigh-risk (UHR) and high-risk (HR) subgroups. Cognitive functions were tested by the Developmental Neuropsychological Assessment II test battery, d2 Test of Attention, and Amsterdam Neuropsychological Tasks. Temperament was assessed by the Temperament in Middle Childhood and Early Adolescent Temperament Questionnaires. Results: The BO sample consisted of 5 BD, 17 UHR, and 41 HR participants. We did not observe any significant differences between the BO and CO groups or between the UHR, HR, and CO subgroups (Hedges' g = 0.21-0.39) in cognitive functioning. The BO differed significantly in some temperament traits from the CO (g = 0.42-0.61), while the UHR subgroup exhibited lower effortful control and attention focusing than both HR and CO participants (g = 0.92-1.19). Limitations: The cross-sectional design and wide age range of the sample limited our findings. Conclusions: Neuropsychological impairment does not seem to be a trait marker of BD in the premorbid stage. Temperament with low effortful control and low attention focusing might be associated with the development of mood disorders in BO.

Cross-Cultural Differences in Temperament: Comparing Paternal ratings of US and Dutch infants

This study conducted longitudinal comparisons of US and Dutch paternal ratings of temperament, measured via the Infant Behaviour Questionnaire-Revised, at 4 months (US n= 99; Dutch n= 127) and 12 months (US n= 66; Dutch n= 112) of age. US fathers rated their infant higher in the broad temperament trait Surgency, and its subscales vocal reactivity, high-intensity pleasure, and activity level. US fathers also rated their infants higher in Negative Emotionality, and its subscales of sadness, distress to limitations, and fear. Dutch infants received higher ratings in falling reactivity. Though the cultures did not differ in ratings of Orienting/regulatory capacity, US infants were higher on the subscale duration of orienting, and lower in soothability. Significant culture-by-age and culture-by-gender interactions were also noted. Overall, results are largely consistent with those reported for Dutch mothers (Sung et al., 2014) and speak to considerable differences in early temperament development between cultures viewed as largely similar because of their Western/individualistic orientations.

Adaptation of the Infant Behavior Questionnaire-Revised for use in Ethiopia: Expanding cross-cultural investigation of temperament development

Cross-cultural differences in temperament were evaluated for Ethiopian (N=109) and U.S. (N=109) samples of infants. We anticipated that the Sidama version of the Infant Behavior Questionnaire-Revised (IBQ-R; Gartstein & Rothbart, 2003) developed for use in Ethiopia would demonstrate satisfactory psychometric properties, and hypothesized significant cross-cultural differences in levels of fine-grained temperament characteristics. Interactions between culture, infant age, and sex were also considered. Internal consistency was satisfactory for 13 of the 14 IBQ-R scales (with a somewhat low estimate observed for Duration of Orienting), and an examination of the structure indicated patterns similar to those observed in the US, and elsewhere. Differences between Ethiopia and the US were noted for Activity Level, Distress to Limitations, Fear, Smiling/Laughter, Falling Reactivity, Cuddliness/Affiliation, Sadness, Approach, and Vocal Reactivity. Parents of infants in the US reported higher levels of attributes associated with Surgency/Positive Affectivity (Activity, Smiling/Laughter, Approach Vocal Reactivity), whereas Ethiopian infants' scores were higher for Distress to Limitations and Fear, linked with the over-arching temperament factor of Negative Emotionality; however, US infants received higher ratings on Sadness, also associated with this factor. Higher Falling Reactivity, a regulation-related attribute, was reported for Ethiopian infants, with US babies receiving higher Cuddliness/Affiliation scores. Significant culture*age interactions were observed for Activity and Fear, along with a significant culture*age*sex interaction for Distress to Limitations.

Cross-Cultural Comparisons of Infant Fear

Cross-cultural investigations addressing the development of individual differences are important because these speak to the generalizability of results and the extent to which the development of temperament and personality differs by culture. The present study was aimed at comparing manifestations of fear, defined in infancy as startle or distress to sudden changes in stimulation (e.g., facial/bodily expressions of fear), and inhibited approach to novelty (e.g., escape/avoidance), for samples from Spain ( n = 51) and the United States ( n = 102). We obtained data from mothers of U.S. and Spanish infants at 12 months of age, also observing these babies in the context of a structured laboratory procedure designed to elicit fearful reactivity. Data reduction efforts produced coherent observation-based fearfulness constructs for both groups, and individual indicators were also examined. Significant differences between U.S. and Spanish infants for the observation-based fear composite and component indices of distress vocalizations, bodily fear, and escape intensity, but not for the parent-report of this attribute, were demonstrated. A significant culture-by-gender interaction emerged for the laboratory-based fear composite and the intensity of facial fear indicator, wherein Spanish female infants exhibited higher intensity of expression, relative to the U.S. counterparts.

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.

Does daily distress make parents prone to using psychologically controlling parenting?

The aim of the present study was to investigate whether parental daily distress in terms of negative emotions is associated with the daily variation in parental use of psychological control with their children. Whether parental positive emotions play a role in the use of psychological control was also investigated. The participants were 149 Finnish families with a child between the ages of 6 and 7 years. Parents’ negative and positive emotions, children’s misconduct, and parental use of psychological control when interacting with their children were measured daily using diary questionnaires filled in by the mothers and fathers over 7 successive days in the fall term of the children’s first grade and, for replication purposes, again in the spring term. The results of multilevel modelling showed that, after controlling for the level of children’s misconduct on a particular day, mothers’ and fathers’ negative daily emotions were related to a high level of psychological control in parenting. This relation was evident particularly when combined with parental perception of a high level of child misconduct. Positive emotions, in turn, were not found to be related to the daily variation in the use of psychological control. The results showed further that, at the level of individuals, mothers’ and fathers’ high overall level of negative emotions across the week was related to a high overall level of psychologically controlling parenting.

Focusing on the positive: a review of the role of child positive affect in developmental psychopathology

This review proposes a transactional model of child positive affect (PA) to reflect the ways that PA, in various contexts, may confer both risk and protection for psychosocial adjustment. Though research has largely explored the ways that low PA relates to maladjustment in youth, much less research has focused on the ways that PA can facilitate adjustment, particularly under conditions of risk. Yet, theory suggests that a greater emphasis on PA as a protective factor is an important endeavor in developmental psychopathology research; such conceptual issues are explored in this review. This review also seeks to spur a more nuanced approach to the study of child PA through the use of increased multi-method, longitudinal assessments as well as the consideration of contextual factors. Building upon this research base is important for aiding in the development of intervention and prevention efforts that attempt to promote positive psychosocial development and mitigate the course of psychopathology in youth at risk for PA difficulties.

Exploring temperamental differences in infants from the United States of America (US) and the Netherlands

This longitudinal study employed the Infant Behavior Questionnaire-Revised in assessing temperamental differences between infants at 6 months (n = 114 US, 184 Dutch) and 12 months (n = 92 US, 172 Dutch) from the United States of America and The Netherlands. Main effects indicated that Dutch infants were rated higher on the Orienting/Regulatory Capacity factor and fine-grained dimensions of Smiling and Laughter, Falling Reactivity, Cuddliness, Low-Intensity Pleasure, and Soothability; whereas US infants received higher ratings on the Negative Affectivity factor and on dimensions of Activity Level, Vocal Reactivity, Fear, Frustration, and Sadness. Cultural differences for Orienting/Regulatory Capacity were more pronounced in early infancy, cultural differences for Fear were stronger in late infancy, and US infants demonstrated higher Duration of Orienting at 12 months only. Culture also appeared to impact the pace of consolidation of temperamental characteristics, with greater stability exhibited by US than Dutch infants in Smiling and Laughter and Vocal Reactivity.

Early Temperament in Japan, the United States, and Russia

The present study addressed differences in infant and toddler temperament, utilizing translations of the Infant Behavior Questionnaire–Revised (IBQ-R) and the Early Childhood Behavior Questionnaire (ECBQ), for children growing up in the United States, Russia, and Japan. Results indicated a number of significant differences in higher-order dimensions and fine-grained components of early temperament between the three cultural groups. U.S. children scored higher for Surgency and related traits, compared to Japanese and Russian children; Negative Affectivity showed the opposite pattern of cross-cultural differences, wherein Japanese children received the highest scores from their caregivers. In addition, Japanese infants and toddlers scored lower for Effortful Control. Significant Culture × Age interactions indicated that patterns of cross-cultural differences in different age groups varied across and within the three higher-order dimensions. Surgency, as well as positive affect to both low and high levels of intensity, showed a consistent pattern of decreasing cultural differences with age.
