On the association of interparental conflict with developing behavioral inhibition and behavior problems in early childhood.

Associations between interparental conflict and the development of temperament characteristics have seldom been addressed; moreover, studies on the impact of interparental conflict on developing behavior problems in infancy and early childhood are relatively rare. The authors therefore aimed to contribute to the study of these issues. A sample of 64 families was investigated longitudinally. At the infant age of 4 months, negative emotionality was measured with a laboratory routine. When infants were 4, 8, and 12 months old, maternal sensitivity was assessed during home observations, and interparental conflict was measured by means of questionnaires. When infants were 30 months old, behavioral inhibition was measured in 2 laboratory fear episodes, and behavior problems were assessed with a structured clinical interview of the primary caregiver. Interparental conflict and infant negative emotionality were significantly and independently associated with subsequent behavioral inhibition. The association of interparental conflict with behavior problems was moderated by infant negative emotionality. Infants high in negative emotionality developed more serious behavior problems when exposed to high interparental conflict, whereas the association was not significant in infants low in negative emotionality.     

The reliability and validity of the Infant Behavior Questionnaire-Revised

The reliability and validity of the Infant Behavior Questionnaire-Revised was examined in a sample of 6-month-old infants and their parents. One hundred and fifteen mothers and 79 fathers completed the IBQ-R and a measure of depression and 98 infants participated in a laboratory assessment of temperament. Internal consistency reliability was adequate for all 14 IBQ-R subscales for both mothers and fathers and inter-rater reliability of mother and father reports was demonstrated for 11 of 14 subscales. Convergent validity was established between observed fear and mother reported fear and father reported approach. Parent depression and infant gender were examined as moderators of the concordance between parent reported and observed temperament. As predicted, concordance was higher when parents reported low versus high symptoms of depression. Infant gender did not alter concordance.     

Human milk cortisol concentration predicts experimentally induced infant fear reactivity: moderation by infant sex

Little consideration has been given to the possibility of human infant development being shaped via lactocrine programming, and by breast milk cortisol levels specifically. Despite animal models indicating that glucocorticoid (GC) exposure via lactation might modify brain development and behavior, only one study has reported that milk cortisol levels were positively associated with infant negative affectivity, especially fearfulness and sadness—early emerging risk factors for internalizing difficulties such as anxiety. The aim of the current study was to investigate whether human milk cortisol is associated with mother‐reported fearfulness and experimentally induced infant fear reactivity. Mother‐infant dyads (n = 65) enrolled in the FinnBrain Cohort Study participated. Breast milk samples were obtained 2.5 months postpartum, and milk cortisol concentrations were ascertained using validated luminescence immunoassay methodology. Infant fear reactivity was assessed using maternal reports 6 months postpartum and in a laboratory 8 months postpartum. There was a significant interaction between infant sex and milk cortisol such that higher milk cortisol was related to higher infant fear reactivity in a laboratory setting in girls (β = 0.36, p = .04) but not in boys (β = ?0.15, p = .40). Milk cortisol was not associated with mother‐reported infant fearfulness. Results suggest that higher human milk cortisol concentrations are associated with elevated experimentally induced fear in infancy. Findings support lactocrine programming, and suggest that mothers may “communicate” vital information about stressful environments via cortisol contained in breast milk, shaping girls' early emotional reactivity.     

Mothers' facial expressions of pain and fear and infants' pain response during immunization

The goal of the current study was to examine the relationship between mothers' spontaneous facial expressions of pain and fear immediately preceding their infants' immunizations and infants' facial expressions of pain immediately following immunizations. Infants' observations of mothers' faces prior to immunization also were examined to explore whether these observations moderated the effect of mothers' facial expressions on infant pain. The final sample included 58 mothers and their infants. Video data were used to code maternal facial expressions, infants' observations, and infants' expressions of pain. Infants who observed their mothers' faces had mothers who expressed significantly more fear pre‐needle. Furthermore, mothers' facial expressions of mild fear pre‐needle were associated with lower levels of infants' pain expression post‐needle. A regression analysis confirmed maternal facial expressions of mild fear pre‐needle as the strongest predictor of infant pain post‐needle after controlling for infants' observations of mothers' faces. Mothers' subtle facial expressions of fear may indicate a relationship history of empathic caregiving that functions to support infants' abilities to regulate distress following painful procedures. Interventions aimed at improving caregiver sensitivity to infants' emotional cues may prove beneficial to infants in pain. Future directions in research are discussed.     

Blood/injury fear, fainting and avoidance of medically-related situations: a family correspondence study

The relationship of mutilation fear and fainting was examined in 204 students, (103 fainters and 101 non-fainters) by administering a series of questionnaires and a structured interview concerning the history, effects and circumstances of their fear and fainting. Two hundred and sixty of their parents completed the same scales along with a self-report version of the structured interview. Subjects were classified according to their fainting status and level of fear based on Mutilation Questionnaire scores, as phobic, fearful, and non-fearful fainters, and fearful non-fainters. Phobic and fearful fainters avoided significantly more medical and related situations due to their fear and fainting than fearful non-fainters and non-fearful fainters. Medical avoidance was best predicted by a linear combination of subjects' estimated probability of future fainting and number of past faint episodes. More females reported fainting and females reported greater fear, but they did not differ from males in fear-motivated avoidance of medical situations. A significant parent-child correspondence was found for fainting, but not for fear nor for avoidances. Implications of these findings for fear and fainting acquisition and its relation to avoidance were discussed.     

Fear and anxiety as separable emotions: an investigation of the revised reinforcement sensitivity theory of personality

The Gray and McNaughton (2000) theory draws on a wide range of animal data to hypothesize that the emotions of fear and anxiety are separable. The authors tested their hypothesis in two studies. The first study examined associations between scores on questionnaire measures of fear, anxiety, and neuroticism; correlational analysis revealed that fear and anxiety are not interchangeable constructs. The second study examined associations between scores on questionnaire measures of fear/anxiety and performance in a military training setting; regression analysis revealed that fear captured significant variance in performance that was not shared with anxiety. These results imply that hypotheses derived from nonhuman animal data may hold important implications for understanding human emotion and motivation, especially in relation to fear and anxiety.     

Schizotypy and hemisphere function—IV : Story comprehension under binaural and monaural listening conditions

An experiment is reported examining the story-comprehension performance of normal Ss under left ear, right ear and binaural listening conditions, the results being related to scores on the schizotypy (STA) scale of a previously described questionnaire (STQ). Hypotheses were derived from the observations of other investigators that schizophrenics and the children of schizophrenics show impaired binaural relative to monaural and poor left ear performance on the task; a pilot study had indicated that this might also be the case in normal high STA scorers. Results of the main experiment failed to confirm predictions, though in male Ss several significant effects were observed. High schizotypals showed weakened asymmetry, reflected in better left ear relative to right ear performance, compared with low schizotypals; they also showed a smaller binaural/left ear difference. Some reasons for the discrepancy between these and previous findings using a similar task are considered and the results are discussed in relation to other studies of schizotypy and hemisphere function carried out in our laboratory.     

Cross-cultural aspects of fears in African children and adolescents

The purpose of this study was to compare level and type of fears in Nigerian and Kenyan children using the Fear Survey Schedule for Children, Revised (FSSC-R; [Ollendick, T.H. (1983). Reliability and validity of the Revised Fear Survey Schedule for Children (FSSC-R). Behaviour Research and Therapy, 21, 685-692]). A total of 852 males and females between the ages of 8 and 17 were surveyed. Results indicated that Nigerian children reported significantly higher total fear than Kenyan children and that scores from both countries were higher than those found in the United States, Australia and China. This suggests that the cultures of Kenya and Nigeria may share a common variable that makes reporting of fears greater than that reported by children of other world cultures. In addition, Christian children in both countries reported higher levels of fear on several factors than Muslim children, indicating that Islamic beliefs may encourage children to report less fear or to deal with their fears better than Christian beliefs. Finally, children between the ages of 8 and 12 reported greater fear of the unknown than children between 13 and 17 years of age. Overall, these findings suggest that important cultural, religious and age differences exist for levels of childhood fears reported in Nigeria and Kenya.     

Mother parity as a main and moderating influence on early mother-infant interaction

This study investigated main and moderating effects of mother parity on maternal attitudes and behaviors. In a sample of 87 mothers with 5-month-old infants, relations between determinants of parenting (maternal personality, marital quality, infant negative emotionality) and maternal behavior and attitudes (sensitivity, self-efficacy, mother-reported infant temperament) were examined as a function of parity. Results revealed both main and moderating effects of parity. Multiparous mothers reported higher self-efficacy, whereas primiparous mothers reported more of an increase in marital ambivalence following the baby's birth. The relations of self-efficacy, sensitivity, and mother-reported infant temperament to a laboratory measure of infant crying all differed by parity. In addition, for primiparous mothers, negative personality traits related to reported infant temperament, and for multiparous mothers, marital ambivalence and maternal sensitivity appeared to reflect a compensatory process. These results suggest that parity contributes to explaining how differing family systems influence development during infancy.     

Cardiac physiological regulation across early infancy: The roles of infant surgency and parental involvement with mothers and fathers

High baseline respiratory sinus arrhythmia (RSA) and infant temperament are associated with a child’s ability to self-regulate, but moderators of this association have not been thoroughly examined in the literature. Parents who are more involved might have more opportunities to interact with and soothe their children. The current study examined whether parental involvement moderated the association between infant temperament and baseline RSA with mothers and fathers across early infancy. Participants included families (n = 91) assessed at 4 and 8 months of age. Infant temperamental surgency and parental involvement were measured via parent-report when infants were 4 months old, and infant baseline RSA was measured at 4 and 8 months of age. Results revealed differences in mother versus father predictors of infant baseline RSA. A significant Infant Surgency X Maternal Play interaction was revealed; infants of mothers who were low involvement increased in their baseline RSA as their surgency increased. A significant main effect of father care was found; infants with highly involved fathers had higher baseline RSA. In conclusion, mothers and fathers may differentially influence their infant’s cardiac physiological regulation based on their specific type of involvement.     

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

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

Knowledge and fear of developing Alzheimer's disease in a sample of healthy adults

Alzheimer's disease is the fourth leading cause of death among seniors but its insidious onset makes it difficult to distinguish from age-related decline and little is known about how much knowledge and fear people entertain about this disease. This study examined knowledge and fear of Alzheimer's disease by surveying 127 young (M= 19.6 yr.) and 118 older (M=67.9 yr.) participants. Younger participants obtained a score of 64%, while older participants obtained 58% on the knowledge test. Younger participants reported significantly higher fear overall. Knowledge and Fear scores were not significantly correlated with having a family member or knowing someone with Alzheimer's disease.     

Direct and Indirect Effects of Behavioral Parent Training on Infant Language Production

Given the strong association between early behavior problems and language impairment, we examined the effect of a brief home-based adaptation of Parent–child Interaction Therapy on infant language production. Sixty infants (55% male; mean age 13.47 ± 1.31 months) were recruited at a large urban primary care clinic and were included if their scores exceeded the 75th percentile on a brief screener of early behavior problems. Families were randomly assigned to receive the home-based parenting intervention or standard pediatric primary care. The observed number of infant total (i.e., token) and different (i.e., type) utterances spoken during an observation of an infant-led play and a parent-report measure of infant externalizing behavior problems were examined at pre- and post-intervention and at 3- and 6-month follow-ups. Infants receiving the intervention demonstrated a significantly higher number of observed different and total utterances at the 6-month follow-up compared to infants in standard care. Furthermore, there was an indirect effect of the intervention on infant language production, such that the intervention led to decreases in infant externalizing behavior problems from pre- to post-intervention, which, in turn, led to increases in infant different utterances at the 3- and 6-month follow-ups and total utterances at the 6-month follow-up. Results provide initial evidence for the effect of this brief and home-based intervention on infant language production, including the indirect effect of the intervention on infant language through improvements in infant behavior, highlighting the importance of targeting behavior problems in early intervention.     

The association of paternal mood and infant temperament: A pilot study

Maternal depression is associated with adverse child development, but little is known about the effects of paternal depression. This pilot study estimated the prevalence of paternal depression and mood state, and assessed the relationship between paternal mood and infant temperament. The participants in the study were 98 fathers of newborn babies. Fathers were initially screened for depressed mood (Hospital anxiety and depression scale, and Edinburgh postnatal depression scale), and at 6 months parental mood, infant temperament, couple relationship quality, alcohol use, adverse life events, parenting, and demographics were recorded. Infant fussiness was analysed in relation to paternal mood and other contextual factors using multiple regression. Of the 98 fathers, 48 (49%) completed depression-screening measures. Of these 48 fathers, 4 (8%) reported depressive symptoms above the cut-off for case definition. A total of 48% (N=19) completed measures at follow-up. In the adjusted model, higher paternal depression scores, more traditional attitudes towards fathering, and increased recent life events were related to higher infant fussiness scores; and better couple relationship quality was related to lower fussiness scores. This study showed that 1 in 12 fathers had depressed mood, and lower mood was associated with negative infant temperament. Since the findings of this feasibility study were based on a small sample size the association of paternal mood and child development merits further study using a larger sample of fathers.     

Similarities and differences in mothers' and observers' ratings of infant security on the Attachment Q-Sort

This study examined the similarities and differences in maternal and observer Attachment Behavior Q-Sort ratings (AQS; Waters, 1995) and their relations to dimensions of the developmental ecology - maternal sensitivity, infant irritability, parental stress and psychosocial risk. Data was gathered from low risk (adult mothers; N=44) and high risk mother-infant dyads (adolescent mothers; N=83) when infants were aged 6, 10 and 15 months old, attachment being assessed at 15 months by both mothers and independent observers. A common factor was extracted from both sorts and served to operationalize the similarities between mother and observer ratings. Regressions were conducted to extract maternal and observer AQS scores that were unrelated to each other to represent the difference between the two sorts. Correlation analyses indicated that the common AQS factor was moderately linked to maternal sensitivity and parental stress, and showed a weak association to psychosocial risk and infant irritability. Residual maternal scores showed greater correlations with infant irritability and parental stress than did observer residual scores. Observer scores showed a greater correlation with psychosocial risk than maternal scores. Results suggest that common AQS variance presents a pattern of associations with ecological variables that is coherent with attachment research. Variance related to irritability, stress and risk appear to drive the differences between maternal and observer observations.     

Evidence of a disposition toward fearfulness and vulnerability to posttraumatic stress in dysfunctional pain patients

Few investigations have addressed whether patient subgroups derived using the Multiaxial Assessment of Pain (MAP) [Turk, D. C., & Rudy, T. E. (1987). Towards a comprehensive assessment of chronic pain patients. Behaviour Research and Therapy, 25, 237-249; Turk, D. C., & Rudy, T. E. (1988). Toward an empirically derived taxonomy of chronic pain patients: integration of psychological assessment data. Journal of Consulting and Clinical Psychology, 56, 233-238.] differ with regard to fear and avoidance. It has, however, been reported that dysfunctional patients exhibit more pain-specific fear and avoidance than patients classified as interpersonally distressed or minimizers/adaptive copers [Asmundson, G. J. G., Norton, G. R., & Allerdings, M. D. (1997). Fear and avoidance in dysfunctional chronic back pain patients. Pain, 69, 231-236.]. We attempted to extend these findings by examining two fear constructs that are receiving increased attention in the chronic pain literature-anxiety sensitivity and PTSD. The sample comprised 115 patients with chronic pain. Of these, 14 (12.2%) were classified as dysfunctional, 21 (18.3%) as interpersonally distressed and 47 (40.8%) as minimizers/adaptive copers. Between-group differences were observed on the fear of cognitive and emotional dyscontrol dimension of anxiety sensitivity, total and symptom cluster scores on the PTSD measure, and depression. No differences were observed for the fear of somatic sensations dimension of anxiety sensitivity or agoraphobia, social phobia, and blood/injury fears. Dysfunctional patients generally exhibited elevated scores relative to one or both of the other MAP subgroups on fear of cognitive and emotional dyscontrol, depressed affect, PTSD symptom total score and PTSD symptom cluster scores. As well, a substantial proportion of dysfunctional and interpersonally distressed patients were classified as having PTSD (71.4 and 42.9%, respectively) when compared to minimizers/adaptive copers (21.3%). These results suggest that MAP subgroups differ with regard to their propensity to be(come) fearful and in their likelihood of having PTSD. Theoretical and clinical implications are discussed.     

Comparison of K-ABC performance between at-risk and normal preschool children

This study examined differences in K-ABC performance between at-risk (n = 44) and normal (n = 49) preschool children. For the group at-risk, all of the mean global scores on the K-ABC clustered around a standard score of approximately 90. The normal group's mean scores were 15 to 21 standard-score points higher and clustered near 110. The results of t tests for independent samples indicated that the normal group's scores on both the global scales and K-ABC subtests were significantly higher than the at-risk group's scores in nearly every instance. Correlations among scores were consistent with previous findings for preschoolers on the K-ABC. For the normal group, correlations obtained among the global scales were nearly identical to those reported for the standardization sample. For the at-risk group, however, the correlation of .75 between Sequential processing and Achievement was higher than that (.58) between Simultaneous processing and Achievement.     

Fear of storms and hurricanes in Antillean and Belgian children

The present study assessed fear of hurricanes in children who had been confronted with this natural event (i.e., Antillean children, n=161). Their fear levels were compared to those of children who are unfamiliar with such an event (i.e., Belgian children, n=185). Antillean children reported significantly higher levels of fear of storms than Belgian children did, thus providing support for the notion that exposure to dangerous events promotes children's fears of those events. Surprisingly, however, Antillean children had lower scores on the 'Hurricanes' item than Belgian children. Plausibly, differences in how children interpreted this item may have accounted for this unexpected finding. That is, ratings of Antillean children were probably based on actual experiences with hurricanes, whereas scores of Belgian children presumably reflected appraisal of threat in case they would be confronted with such an event. Implications of this finding for the assessment of childhood fears are briefly discussed.     

Animal fears in the Antipodes: normative data from an Australian sample

The present study investigated reported fear of snakes, spiders and mutilation in an Australian sample ( N =235). Standardized questionnaires were used, and scores from the Australian sample were compared with those obtained by other authors from North American and Swedish samples. The psychometric characteristics of test scores from the Australian sample were similar to those from the North American and Swedish samples. Although there were no differences in reported fear of snakes between the three samples, both the Australian and North American samples reported greater fear of spiders than did the Swedish sample. Females scored higher on all scales than did males, and Australian and North American females reported greater fear of mutilation than did Swedish females. Test-retest reliability in a non-clinical Australian subsample ( n =48) was low for all scales. The results are discussed in terms of the adaptation/habituation hypothesis and the preparedness account of the acquisition of fear.     

Exploring an integrative model of infant behavior: what is the relationship among temperament, sensory processing, and neurobehavioral measures?

Traditionally, developmental psychology, occupational/physical therapy, and behavioral pediatrics view similar infant behaviors from temperament, sensory processing, or neurobehavioral theoretical perspectives. This study examined the relations between similar and unique summary scores of three infant assessments (Early Infancy Temperament Questionnaire - EITQ, the Infant Sensory Profile - ISP, and the NICU Network Neurobehavioral Scale - NNNS) in a healthy sample of 100, one-month-old infants. A Principal Components Analysis of selected subscale scores derived from the three assessments suggested a three-factor model. Temperament and sensory summary scores had the strongest relations on two factors: Sensory-Affective Reactivity and Engagement. A third factor had strong relations between state regulation and motor competence. This new integrative model also validates an existing model and expands explanation of infant behavior across disciplines and methods which have significant implications for assessment, intervention, and management practices.
