Infant behaviour questionnaire – revised version: a psychometric study in a Portuguese sample

Background: Although the original characteristics of temperament tend to remain constant over the course of development, environmental circumstances may influence infants’ reactions and behaviour. Parents’ reports of infant temperament are rich informants of infant behaviours in different contexts.Objective: This study aimed to examine the psychometric properties of the Portuguese version of the Infant Behaviour Questionnaire – Revised (IBQ-R) and test the adequacy of the original and other previously published structures to the Portuguese data.Method: 330 mothers and 81 fathers of children aged between 3 and 12 months completed the Portuguese version of the IBQ-R.Results: The confirmatory factorial analysis revealed a non-adequate model fit of the IBQ-R original structure to the Portuguese data; nonetheless, it did reveal an adequate model fit of a previous published IBQ-R structure. This structure, although only slightly different from the original one, seems to be more suitable for the Portuguese data.Conclusion: This study provides data that indicates that the IBQ-R is a reliable questionnaire to evaluate infant temperament in the Portuguese culture.

Long-term early development research in congenital heart disease (LEADER-CHD): a study protocol for a prospective cohort observational study investigating the development of children after surgical correction for congenital heart defects during the first 3 years of life

IntroductionCongenital heart disease (CHD) is the most common birth defect. Studies on the development of children with CHD point towards deficits in motoric, cognitive and language development. However, most studies...

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 and speak to considerable differences in early temperament development between cultures viewed as largely similar because of their Western/individualistic orientations.

Assessment of temperament in children with profound intellectual and multiple disabilities. A pilot study into the role of motor disabilities in instruments to measure temperament

AbstractResearch on temperament has evolved substantially throughout the last years. Assessing temperament in a child gives information about why the child reacts differently in different situations and can be seen as one of the variables playing a role in determining adaptive and maladaptive outcomes. Insight into the temperament of the child, therefore, facilitates the adaptation of support or child-rearing practices to the specific needs and wishes of the child. The current study aimed at reviewing existing temperament instruments among young children with profound intellectual and multiple disabilities (PIMD). An inventory of the existing instruments, which can determine temperament, was made based on a literature review. A total of 138 articles were found in which temperament was measured. None of these studies included children with PIMD. The Infant Behavior Questionnaire-Revised (IBQ-R) very short form and the Child Behavior Questionnaire (CBQ) very short form seem to be the most appropriate forms ...

Infant Behavior Questionnaire–Revised Very Short Form: A New Factor Structure's Associations With Parenting Perceptions and Child Language Outcomes

ABSTRACTThe Infant Behavior Questionnaire Revised–Very Short Form (IBQ–R VSF; Putnam, Helbig, Gartstein, Rothbart, & Leerkes, 2014) is a new publicly available measure of infant temperament measuring positive affectivity/surgency (PAS), negative emotionality (NEG), and orienting and regulatory capacity (ORC). Although the initial psychometric properties of the 3-factor model appear promising, it has not been administered to a large and diverse sample and its predictive validity has not been established. This study administered the IBQ–R VSF to a diverse sample of 5,639 mothers of infants aged between 23 and 52 weeks. Confirmatory factor analysis found that the 3-factor solution did not meet the requirement for satisfactory model fit. Exploratory factor analysis found that a 5-factor solution (PAS, NEG, Orienting Capacity, Affiliation/Regulation, and Fear) was statistically and conceptually the most parsimonious. All 5 temperament dimensions were found to relate to both mother- and partner-reported infant closeness, parenting confidence, and parenting satisfaction, and four of the dimensions (PAS, Orienting Capacity, NEG, and Fear) related to the infants' communication development. Some parental differences were also found. Together these findings suggest that the 5-factor IBQ–R VSF is a promising measure of infant temperament and is related to parenting perceptions and child language development.

The relationship between attention and deferred imitation in 12-month-old infants

Imitation is a frequent behavior in the first years of life, and serves both a social function (e.g., to interact with others) and a cognitive function (e.g., to learn a new skill). Infants differ in their temperament, and temperament might be related to the dominance of one function of imitation. In this study, we investigated whether temperament and deferred imitation are related in 12-month-old infants. Temperament was measured via the Infant Behavior Questionnaire Revised (IBQ-R) and parts of the Laboratory Temperament Assessment Battery (Lab-TAB). Deferred imitation was measured via the Frankfurt Imitation Test for 12-month-olds (FIT-12). Regression analyses revealed that the duration of orienting (IBQ-R) and the latency of the first look away in the Task Orientation task (Lab-TAB) predicted the infants’ imitation score. These results suggest that attention-related processes may play a major role when infants start to imitate.

Parental Relationship with Twins from Pregnancy to 3 Months: The Relation Among Parenting Stress, Infant Temperament, and Well-Being.

Objective: The transition to parenthood, from pregnancy to postpartum period, is a critical process, particularly for couples expecting twins. There is very little literature regarding the links between anxiety, depression, dyadic adjustment, parental stress, and infant temperament spanning from pregnancy to postpartum. This study has two aims: first, to examine whether mothers’ and fathers’ anxiety, depression, and dyadic adjustment, assessed at the sixth month of pregnancy and 3 months postpartum, are associated with infants’ negative affectivity (NA) and parenting stress; second, to examine whether there is any difference between fathers’ and mothers’ levels of parenting stress and perception of the twins’ temperament, as well as to evaluate, separately for mothers and fathers, whether the levels of parenting stress and perception of child temperament differ for each twin.Method: The study participants were 58 parents (29 couples) and their healthy 58 twin babies (51.7% boys, 48.3% girls). Mothers’ ages ranged from 30 to 44 years, (MAge = 36.3 years, SD = 3.2 years), and fathers’ ages ranged from 32 to 52 years, (MAge = 38.2 years, SD = 4.4 years). The parents, during the pregnancy period and 3 months after delivery, filled out the Edinburgh Postnatal Depression Scale, the State-Trait Anxiety Inventory, and the Dyadic Adjustment Scale. Three months after delivery they also filled out the Parenting Stress Index—Short Form and the Infant Behavior Questionnaire Revised.Results: The analyses showed a significant correlation between parental anxiety/depression symptoms and infants’ NA and parenting stress (in both mothers and fathers). Moreover, compared to fathers, mothers reported higher scores on specific dimensions of the infants’ NA, [t(28) = -2.62 and p < 0.05; t(28) = 2.09 and p < 0.05], and parenting stress, [t(28) = 2.19 and p < 0.05; t(28) = 2.23 and p < 0.05], but only for Twin 2. Finally, the results showed that mothers’ perceptions of child temperament vary between two twins, [e.g., distress to limitations: t(28) = 2.08 and p < 0.05].Discussion: This study highlights the peculiarity of twin parenthood during the fourth trimester. In particular, the differences between twins’ mothers’ and fathers’ perceptions are relevant from a clinical perspective and for perinatal professionals. It would be interesting to study the long-term impact of mothers’ and fathers’ differing perceptions of their twins.

Troubles du comportement alimentaire restrictif du nourrisson et du jeune enfant : évaluation quantitative des interactions parent/nourrisson pendant le repas

IntroductionInterest in the study of early feeding disorders (FD) has steadily increased during recent decades. During this period, research described the importance of the transactional relationships and the complex interplay between caregiver and child over time. On the basis of the previous studies, our study tried to explore the associations between the characteristics of the parents and the temperamental characteristics of the infants with early FD. GoalsA first aim of the present study was to show if parental perception of child temperament (including ability for arousal self-regulation) and parental characteristics (emotional and eating attitudes) are associated with early FD. A second aim was to identify emotional/behavioral difficulties in children with early FD by comparing children with a normal development and children with a diagnosed FD, and to investigate whether there are any correlations between parental emotional and feeding characteristics and a child's eating and emotional-behavioral development. A final aim was to explore if feeding conflict is bound to both infant ability for arousal self-regulatation and caregiver emotional status during meals. MethodParticipants: 58 clinical dyads (children aged 1–36 months) and 60 in the control group participated in the study. The sample of 58 infants and young children and their parents was recruited in a pediatric hospital. They were compared to healthy children recruited in several nurseries. Procedure: all parent-child pairs in the clinical sample were observed in a 20-minute video-recording during a meal using the procedure of the Chatoor Feeding Scale. After the videotaping, parents completed a battery of self-report questionnaires assessing their child's and their own psychological symptom status. Measures: Child's malnutrition assessment was based on the Waterlow criteria. The Child Behavior Checklist (CBCL 1½–5) was used to assess a child's emotional/behavioral functioning. The Infant Behavior Questionnaire-Revised (IBQ-R), a widely used parent-report measure of infant temperament, was used to identify the structure of infant temperament. The Eating Attitude Test-40, a self-report symptom inventory, was used to identify concerns with eating and weight in the adult population. The Chatoor Feeding Scale was used to assess mother–child feeding interactions during a meal based on the analysis of the videotaped feeding session. ResultsAnalyses revealed that children with FD did not have a difficult temperament, especially no disability for arousal of self-regulatation, but their emotional-behavioral functioning is characterized by internalizing problems. Analyses of the EAT-40 showed that mothers of the children diagnosed with FD had significantly higher scores than mothers of the control sample; it means these mothers showed more dysfunctional eating attitudes. In addition, meals were characterized by negative effects in parents in the clinical group. When compared to the control sample, the feeding interactions between children with FD and their parents were characterized by low dyadic reciprocity, high maternal non-contingency, great interactional conflict and struggles with food. However, no significant correlation emerged either between the severity of malnutrition in infants or the conflict during feeding. ConclusionOur study confirms the relations established in previous research. Finally, future longitudinal studies are needed to further clarify and investigate others factors that may be involved in early feeding disorders.

Regulatory Behaviors and Stress Reactivity among Infants at High Risk for Fetal Alcohol Spectrum Disorders: An Exploratory Study

ABSTRACTIntroduction: This article examines regulatory behaviors and physiological stress reactivity among 6–15 month–old infants with moderate to heavy prenatal alcohol exposure (PAE), a group at very high risk for fetal alcohol spectrum disorders and self–regulation impairments, compared to low risk infants with no/low exposure. Participants: Eighteen infants and their biological mothers; nine infants [M= 10.7 (3.1) months] had moderate to heavy PAE and nine [M= 10.7 (2.9) months] had no/low exposure. Methods: Infant biobehavioral responses to the Still Face Paradigm (SFP), a standardized infant social stressor, were examined. Infant behaviors were compared across: 1) play; 2) still–face (stressor); and 3) reunion conditions, using the Infant and Caregiver Engagement Phases coding system. Salivary cortisol samples were taken at baseline, 15 and 30 minutes post SFP. Mothers completed the Infant–Toddler Symptom Questionnaire (ITSC) and Infant Behavior Questionnaire–Revised (IBQ–R). Results: Infants with PAE had significantly higher baseline salivary cortisol levels [0.26 mg/dl (.12 SD)] than controls [0.11 mg/dl (0.03 SD; p ≤ .05]. Behaviorally, infants with PAE demonstrated significantly fewer social monitoring behaviors compared to controls. There were no significant group differences on caregiver-reported regulatory behaviors (ITSC) or temperament characteristics (IBQ–R). Conclusion: Biobehavioral findings revealed greater stress vulnerability and heightened risk for regulatory problems among infants with high–risk levels of PAE. Results need confirmation with a larger sample. These exploratory findings inform future studies designed to investigate early developmental problems among children with PAE and FASD, and support an overarching goal to improve early identification and early intervention strategies for a group of high–risk infants.

Establishing the Measurement Invariance of the Very Short Form of the Infant Behavior Questionnaire Revised for Mothers Who Vary on Race and Poverty Status

ABSTRACTWe examined the measurement invariance of the Infant Behavior Questionnaire Revised–Very Short Form (IBQR–VSF; Putnam, Helbig, Gartstein, Rothbart, & Leerkes, 2014) in a sample of 470 racially (185 White, 285 African American) and socioeconomically diverse mothers (158 below federal poverty threshold, 296 above federal poverty threshold) of infants. Using multigroup confirmatory factor analysis, we demonstrated configural, full metric, and full scalar invariance demonstrating that the 3-factor structure (negative emotionality, positive affectivity/surgency, orienting/regulatory capacity), pattern of item loadings, and item means were comparable for White and African American mothers, and for poor and not poor mothers. In addition, we demonstrated full error invariance across racial groups and partial error variance invariance across poverty status, demonstrating that item reliability was comparable for White and African American mothers, and both those above and below the poverty line (with the exception of a subset of items). Thus, the IBQR–VSF appears appropriate for use in racially and socioeconomically diverse samples.

Early temperament as a predictor of later personality

This study examined developmental relationships between early temperamental dimensions and later personality traits using the Infant Behavior Questionnaire-Revised (IBQ-R), the Early Childhood Behavior Questionnaire (ECBQ) and the Inventory of Child Individual Differences-Short version (ICID-S) in a community sample of 98 children who had participated in a study of early temperament and who provided follow-up data on average seven years later. Analyses revealed a number of significant associations between higher- and lower-order dimensions of early temperament and later personality. Regulatory Capacity in infancy and Effortful Control in toddlerhood were related to personality domain of Conscientiousness, largely due to the contribution of early temperament trait of Low Intensity Pleasure. The findings showed considerable heterotypic continuity of individual differences, both within-domain and cross-domain, and highlighted the predictive effect of early regulatory traits.

The Infant Behavior Questionnaire-Revised: Factor structure in a culturally and sociodemographically diverse sample in the United States

The recommended factor structure for the Infant Behavior Questionnaire-Revised (IBQ-R), a widely used parent-report measure of infant temperament, has limited empirical support. Moreover, the recommended factors were developed using homogenous samples not representative of current United States (U.S.) sociodemographics. The objective of this study was to examine the factor structure of the IBQ-R in a culturally and sociodemographically diverse U.S. cohort (N=380 mother-infant dyads). Mothers were assessed during pregnancy on a range of cultural and sociodemographic characteristics and completed the IBQ-R when their infants were 6 months of age. The sample was diverse on maternal marital status, educational attainment, household income, race/ethnicity, primary language spoken, and country of birth. Initial confirmatory factor analysis for the recommended three-factor model yielded a poor fit. Modifications employed in other studies failed to improve model fit. An exploratory factor analysis revealed an acceptable model fit for a three-factor solution that showed similarities to as well as differences from the originally proposed factor structure. Additional analyses suggested lack of invariance on several factor and scale scores by maternal country of birth, race/ethnicity, and household income. The findings suggest that the commonly used IBQ-R factor structure may need to be adjusted for diverse samples and deserves further study.

Infant Predictors of Toddler Effortful Control: A Multi-method Developmentally Sensitive Approach

Effortful control (EC) is a form of self-regulation characterized by inhibition of dominant responses in favour of more adaptive subdominant responses. In the present study, temperamental antecedents in infancy were examined in relationship to toddler EC. Parents reported on infant temperament at 6, 8, 10, and 12 months, using the regulatory capacity/orienting (RCO) factor of the Infant Behavior Questionnaire-Revised. Laboratory indicators of this temperamental construct were also collected at each time point via the Temperament Laboratory Assessment. Relations between changes in temperament across the first year of life and toddler EC (mean age = 22 months) were examined using multilevel modelling. Parent-reported RCO and the component subscale of cuddliness more specifically were the only temperamental variables that prospectively predicted toddler EC. Copyright © 2016 John Wiley & Sons, Ltd.

Does temperament influence language development? Evidence from preterm and full-term children

The aims of this study are: (1) to describe language and temperament characteristics of one group of low risk preterm (PR) children and a group of full-term (FT) children and (2) to identify those factors which can predict language outcomes at 30 months of age, with special attention on temperament. There is evidence of differences between very or extremely PR and FT children in relation to characteristics of temperament and language development. However, not many studies have been carried out with healthy PR children.The participants were 142 low risk PR children (mean gestational age (GA): 32.60 weeks) and 49 FT children (mean GA 39.84 weeks). The temperament of the children was assessed at 10 months of age through the Infant Behavior Questionnaire-Revised (IBQ-R). At 22 months of age the cognitive development of the children was assessed through the Spanish adaptation of the Batelle Developmental Inventory (BDI). In order to assess the children's language development the Galician adaptation of the MacArthur–Bates CDI was applied at 30 months of age. In addition, socio-demographic information about the children and their families was gathered at birth.The results indicate that there were no significant differences in the language measures of interest (word production, MLU3, and sentence complexity) between groups. The only differences found between the PR and the FT children in the IBQ-R were restricted to the smiling and laughter and the fear subscales. Hierarchical regression analyses performed indicate that GA did not have any predictive effect on language measures taken at 30 months. Cognitive scores were an important predictor of language measures, although certain temperament subscales contributed in a significant way to the variance of language measures, particularly low intensity pleasure, approach, high intensity pleasure, sadness, and vocal reactivity. Therefore, extroverted (positive affectivity) temperament seems to be beneficial for language development.

The effect of preterm birth on infant negative affect and maternal postpartum depressive symptoms: A preliminary examination in an underrepresented minority sample

ObjectiveTo examine the effect of preterm birth on maternal postpartum depressive symptoms and infant negative affect in an underrepresented minority sample. MethodParticipants were 102 mothers and their 3- to 10-month-old infants. Mothers completed the Edinburgh Postnatal Depression Scale and the Infant Behavior Questionnaire-Revised. ResultsRelative to normative samples, the current underrepresented minority sample of mostly Hispanics and Blacks displayed high rates of preterm birth (30%) and maternal postpartum depressive symptoms (17%). Preterm birth had a significant direct effect on postpartum depressive symptoms and infant negative affect. Additionally, there was an indirect effect of postpartum depressive symptoms on the relation between preterm birth and infant negative affect. Specifically, lower birth weight and gestational age predicted higher levels of depressive symptoms in the mother, and higher levels of depressive symptoms in the mother, in turn, predicted higher levels of infant negative affect. ConclusionFindings emphasize the importance of screening for postpartum depressive symptoms and infant negative affect among mothers and their preterm infants, especially among families from underrepresented minority backgrounds.

Prenatal exposure to methyl mercury from fish consumption and polyunsaturated fatty acids: associations with child development at 20 mo of age in an observational study in the Republic of Seychelles

Fish is a rich source of n-3 polyunsaturated fatty acids (PUFAs) but also contains the neurotoxicant methyl mercury (MeHg). PUFAs may modify the relation between prenatal MeHg exposure and child development either directly by enhancing neurodevelopment or indirectly through the inflammatory milieu. The objective was to investigate the associations of prenatal MeHg exposure and maternal PUFA status with child development at 20 mo of age. The Seychelles Child Development Study Nutrition Cohort 2 is an observational study in the Republic of Seychelles, a high-fish-eating population. Mothers were enrolled during pregnancy and their children evaluated at 20 mo of age by using the Bayley Scales of Infant Development II (BSID-II), the MacArthur Bates Communicative Development Inventories (CDI), and the Infant Behavior Questionnaire-Revised. There were 1265 mother-child pairs with complete data. Prenatal MeHg exposure had no direct associations with neurodevelopmental outcomes. Significant interactions were found between MeHg and PUFAs on the Psychomotor Developmental Index (PDI) of the BSID-II. Increasing MeHg was associated with lower PDI but only in children of mothers with higher n-6/n-3. Among mothers with higher n-3 PUFAs, increasing MeHg was associated with improved PDI. Higher maternal docosahexaenoic acid (DHA) was associated with improved CDI total gestures (language development) but was significantly adversely associated with the Mental Development Index (MDI), both with and without MeHg adjustment. Higher n-6:n-3 ratios were associated with poorer scores on all 3 CDI outcomes. We found no overall adverse association between prenatal MeHg exposure and neurodevelopmental outcomes. However, maternal PUFA status as a putative marker of the inflammatory milieu appeared to modify the associations of prenatal MeHg exposure with the PDI. Increasing DHA status was positively associated with language development yet negatively associated with the MDI. These findings may indicate the existence of an optimal DHA balance with respect to arachidonic acid for different aspects of neurodevelopment.

Maternal mindfulness during pregnancy and infant socio-emotional development and temperament: The mediating role of maternal anxiety

BackgroundAccumulating evidence shows that maternal anxiety during pregnancy adversely affects child outcomes. The positive effects of maternal psychosocial factors during pregnancy on child outcomes are not yet studied. This prospective study addresses the association between maternal mindfulness during pregnancy and socio-emotional development and temperament in 10months-old infants. We also investigated whether this association was mediated by maternal anxiety. MethodMothers (N=90) provided information about mindfulness and anxiety at the beginning of the second trimester of pregnancy. Infant socio-emotional development (Ages and Stages Questionnaire: Social Emotional; ASQ:SE) and temperament (Infant Behaviour Questionnaire—Revised; IBQ-R) were assessed at age 10months. ResultsHigher maternal mindfulness during pregnancy was associated with less infant self-regulation problems and less infant negative affectivity. Mediation analysis showed that maternal anxiety mediated the association between infant self-regulation problems and maternal mindfulness. ConclusionThese results suggest that maternal mindfulness during pregnancy may have positive effects on infant development. This association may be mediated by reduced anxiety symptoms in pregnant women who score high on mindfulness. Additional replication studies are needed using objective measures of infant behavioural/emotional outcomes and mindfulness of the mother during child development.

Parental Anxiety, Parenting Behavior, and Infant Anxiety: Differential Associations for Fathers and Mothers

Most studies investigating the role of parenting behavior in the intergenerational transmission of anxiety from parents to children have focused on mothers. However, recent research suggests that mothers and fathers may parent differently and may differentially affect the development of child anxiety. Theoretical models propose that anxious parents engage in more anxiety-provoking and less anxiety-reducing parenting behavior than non-anxious parents. However, findings are inconsistent, possibly because most studies have not differentiated between anxiety disorders. Therefore, it remains unclear which specific anxiety disorders are linked to parenting behavior. This study examined (1) whether symptoms of specific parental anxiety disorders are linked to overinvolvement and challenging parenting behavior towards infants; and (2) the differential relationship of maternal/paternal overinvolvement and challenging parenting behavior with infant anxiety. Parents of 81 infants (10–15 months) completed the Overinvolvement and Challenging parenting behavior (CPB) scales of the Comprehensive Parenting Behavior Questionnaire, the Screen for Child Anxiety Related Emotional Disorders-Adult version, and the Fear scale of the Infant Behavior Questionnaire-Revised. Linear regressions showed that mothers’ generalized anxiety disorder symptoms were associated with less CPB and more overinvolvement, whereas fathers’ social anxiety disorder symptoms were associated with less CPB and more overinvolvement. Moreover, paternal, but not maternal, CPB was associated with less infant anxiety, and overinvolvement with more infant anxiety. Findings suggest that (1) different dimensions of paternal/maternal anxiety are linked to their parenting behavior; (2) maternal/paternal parenting behaviors are differentially associated with infant anxiety.

The effects of ‘does not apply’ on measurement of temperament with the Infant Behavior Questionnaire—Revised: A cautionary tale for very young infants

BackgroundThe Infant Behavior Questionnaire—Revised (IBQ-R) is a widely used parent report measure of infant temperament. Items marked ‘does not apply’ (NA) are treated as missing data when calculating scale scores, but the effect of this practice on assessment of infant temperament has not been reported. AimsTo determine the effect of NA responses on assessment of infant temperament and to evaluate the remedy offered by several missing data strategies. Study designA prospective, community-based longitudinal cohort study. Subjects401 infants who were born>37weeks of gestation. Outcome measuresMothers completed the short form of the IBQ-R when infants were 3-months and 6-months of age. ResultsThe rate of NA responses at the 3-month assessment was three times as high (22%) as the rate at six months (7%). Internal consistency was appreciably reduced and scale means were inflated in the presence of NA responses, especially at 3-months. The total number of NA items endorsed by individual parents was associated with infant age and parity. None of the missing data strategies completely eliminated problems related to NA responses but the Expectation Maximization algorithm greatly reduced these problems. ConclusionsThe findings suggest that researchers should exercise caution when interpreting results obtained from infants at 3months of age. Careful selection of scales, selecting a full length version of the IBQ-R, and use of a modern missing data technique may help to maintain the quality of data obtained from very young infants.

Infant temperament and feeding history predict infants' responses to novel foods

The purpose of the present study was to investigate whether infant temperament and previous feeding history were associated with infants' acceptance and rejection of a novel food at 12 months of age. Mother–infant dyads (n = 89) were video-recorded during a novel food (hummus, cottage cheese) feeding task. Infants' reactions (acceptance and rejection behaviors) and maternal responsiveness and affect during the interaction were coded from the recordings by teams of coders. Mothers reported on their infants' temperamental approach via the Infant Behavior Questionnaire-Revised (IBQ-R) and their infants' feeding history (previous exposure to solid foods and exclusive breastfeeding). Regression analyses revealed that infants rated lower on approach showed less acceptance of the first offer of novel food than infants rated higher on approach. Additionally, low approach infants who were previously exposed to a greater number of solid foods showed fewer rejection behaviors in response to the later offers of food. Exclusive breastfeeding for 4 months did not appear to have an effect on acceptance or rejection. Finally, greater maternal responsiveness was related to the infants' acceptance of the new food whereas lower maternal responsiveness was associated with rejection of the novel food. These results suggest that the acceptance and rejection of new foods by infants is dependent upon their temperament and previous exposure to solid foods, as well as the manner in which mothers present the novel food.
