Mother-child interaction at age two years and perceived difficult temperament

The current study investigated a hypothesized link between early child temperament and later problem behavior. Early temperament was assessed at ages 6, 13, and 24 months via mother ratings on age-appropriate versions of the Infant Characteristics Questionnaire. The 24-month form was developed in this study. Factor analyses of the questionnaire indicated a clear difficultness factor that was similar in content across all 3 ages. The 6-, 13-, and 24-month difficultness factors were correlated with home observation measures of mother-toddler interaction at age 24 months. Home observation indexes focused on situations where the mother tried to control the toddler's "trouble" behavior. Children rated by their mothers as difficult at 24 months were found to approach "mild trouble" more frequently than children perceived as easy or average. Furthermore, their mothers used intrusive control tactics more frequently than mothers of easy or average children. Analysis of behavior sequence variables showed that difficult children resisted their mothers' control attempts significantly more often than easy or average children, that is, had more conflict with the mothers. The 6- and 13-month difficultness scores predicted both the 2-year-old difficultness rating and the observed conflict indexes. It is suggested that the conflict observed in the interaction between the difficult 2-year-olds and their mothers is conceptually similar to the conflictual behavior characteristic of older, clinically referred, socially aggressive children and their mothers. Thus, the conflicted interactions found at age 2 years may represent an empirically based link between difficult infant temperament and the development of childhood problem behavior.     

Infant Proneness-to-Distress Temperament, Maternal Personality, and Mother-Infant Attachment: Associations and Goodness of Fit

66 mother-infant pairs were examined when the infants were 9 and 13 months. The purpose of this report was to examine relations between infant proneness-to-distress temperament, maternal personality characteristics, and mother-infant attachment. There were no main-effect relations between infant proneness-to-distress temperament as assessed at 9 months and infant attachment classification at 13 months. This was true whether security of attachment (A and C vs. B) or proposed temperament (A1-B2 vs. B3-C2) groupings of attachment classifications were examined. Infant proneness-to-distress temperament, however, was associated with maternal behavior and personality. Furthermore, security of attachment could be predicted by an interaction between maternal personality and infant proneness-to-distress. The importance of considering goodness-of-fit relations in predicting attachment security is discussed.     

Conditions of Continuity and Discontinuity in Infant Negative Emotionality: Newborn to Five Months

This study investigated infant and caregiving-environment variables associated with continuity and discontinuity in infant negative emotionality between the newborn period and 5 months of age. Comparisons were made between groups of infants who evidenced similar levels of crying as neonates but differed by 5 months of age. For initially high-crying infants, mother personality traits, marital quality, and infant variables measured neonatally discriminated stable from changing infants. Ratings of mother sensitivity and infant responsiveness made at 5 months of age also related to continuity and discontinuity in negative emotionality over the first 5 months.     

Positive Affectivity and Fear Trajectories in Infancy: Contributions of Mother–Child Interaction Factors

Fear and positive emotionality were considered in a growth modeling context. Mothers, primarily Caucasian (91.9%) and of middle socioeconomic status, participated in play interactions with infants at 4 months (N = 148). Infant fear and positive affectivity were evaluated at 6, 8, 10, and 12 months of age. A linear trajectory was superior in explaining growth for parent report and observation‐based indicators of positive affectivity and parent report of fearfulness; a piecewise model explained the nonlinear growth of observation‐based fear. Responsiveness in mother–infant interactions emerged as a significant predictor of the fear trajectory, with higher sensitivity predicting lower levels of observed fear. Reciprocity, tempo, emotional tone, and intensity of mother–infant interactions also made significant contributions to temperament development; however, analyses addressing these were exploratory.     

Measurement of infant difficultness.

The Infant Characteristics Questionnaire (ICQ) was developed as a short, factor-analytic screening device for difficultness. Responses of 322 mothers of 4-6-month-old infants suggested that they regard the fussy, hard-to-soothe, labile infant as difficult. Mother report on the ICQ, particularly on the main fussy-difficult factor was found to have adequate reliability over time and convergence with the Carey Survey of Temperamental Characteristics, with father report on the ICQ, and, to a lower degree, with home data collected by independent observers. It was also found that mother characteristics may affect perceptions of infant difficultness: multiparous, extraverted mothers tended to rate their infants as easy.     

More Than Meets the Eye: Parental and Infant Contributors to Maternal and Paternal Reports of Early Infant Difficultness

Objectives. This study examined correspondences among maternal and paternal ratings of infant temperament, parental psychological functioning, and infant behavior. Design. Participants included 120 families. When infants were 6 weeks old, mothers and fathers completed the Infant Characteristics Questionnaire (ICQ); reported on their own levels of anxiety, depressive symptoms, and parenting stress; and completed a 3-day diary of their infants' behavior. Infant irritability was assessed in a laboratory situation. Results. Fathers rated their infants' temperament somewhat more negatively, but there was significant correspondence between maternal and paternal ratings on the temperament factors of fussiness, unadaptability, dullness, and a difficultness composite. Higher infant difficultness was consistently associated with parenting stress. Infant behavioral fussiness, as measured by 3-day diaries, was significantly correlated with temperament ratings by both parents and with irritability observed in the laboratory setting. Maternal psychological distress was weakly predictive of ratings of infant difficultness; infant behaviors (diary and laboratory-based irritability) accounted for 15 to 17% of the variance. Paternal psychological distress and infant behaviors contributed equally to difficultness ratings. Conclusions. Mothers and fathers are influenced by somewhat different factors in perceiving their babies' temperament, but both maternal and paternal reports have a basis in laboratory- and diary-based behaviors. Results indicate the strong contributing influence of infant irritability to the perception of difficult temperament and support the validity of parental reports of infant irritability in the first 6 weeks of life.     

Modalities of Infant–Mother Interaction in Japanese,Japanese American Immigrant,and European American Dyads

Cultural variation in relations and moment‐to‐moment contingencies of infant–mother person‐oriented and object‐oriented interactions were compared in 118 Japanese, Japanese American immigrant, and European American dyads with 5.5‐month‐olds. Infant and mother person‐oriented behaviors were related in all cultural groups, but infant and mother object‐oriented behaviors were related only among European Americans. Infant and mother behaviors within each modality were mutually contingent in all groups. Culture moderated lead–lag relations: Japanese infants were more likely than their mothers to respond in object‐oriented interactions; European American mothers were more likely than their infants to respond in person‐oriented interactions. Japanese American dyads behaved like European American dyads. Interactions, infant effects, and parent socialization findings are set in cultural and accultural models of infant–mother transactions.     

A longitudinal twin study of stability of components from Bayley's Infant Behavior Record

Factor scores from Bayley's Infant Behavior Record, obtained from about 300-400 infant twins at 6, 12, 18, and 24 months, were selected to represent 3 aspects of infant behavior: task orientation, test affect-extraversion, and activity. Age-to-age correlations for the scores yielded a simplex pattern of low to moderate order. Further age-to-age analyses by twin pairs generally showed that the identical twins, as compared with same-sex fraternal twins, generated more within-pair similarities for profiles of the factor scores across 2 overlapping age ranges: 6-18 months, and 12-24 months. Overall, the findings indicated that there is reordering of individual differences for aspects of infant behavior from one age to the next, but the sequence of reordering is somewhat structured in accord with genotypic similarity. The longitudinal findings are also discussed within the context of change and continuity of the individuality of infant temperament.     

Lenghth of Maternity Leave and Quality of Mother-Infant Interactions

The aim of this study was to assess the association between the length of maternity leave and the quality of mother-infant interactions; 198 employed mothers of 4-month-old infants were interviewed and videotaped in their homes during a feeding time. Hierarchical multiple regression analyses indicated a direct association between shorter length of leave and more negative affect and behavior in maternal interactions with their infants. Infant and mother stressor/protective variables added significantly in predicting the quality of the mother-infant relationship. There were also significant interaction effects between the length of leave and these variables. Mothers who either reported more depressive symptoms or who perceived their infant as having a more difficult temperament and who had shorter leaves, compared with mothers who had longer leaves, were observed to express less positive affect, sensitivity, and responsiveness in interactions with their infants. The public policy implications of the relation between length of maternity leave, maternal and infant individual differences, and the quality of mother-infant interactions are discussed.     

Interactions of perinatal depression versus anxiety and infants' early temperament trajectories

This study examines the interplay between maternal depression/anxiety and infant temperament's developmental trajectory in 1687 Swedish-speaking mother–infant dyads from Uppsala County (2009–2019), Sweden. The sample includes a high proportion of university-educated individuals and a low share of foreign-born participants. Maternal depressive and anxiety symptoms were assessed using the Edinburgh Postnatal Depression Scale during gestational weeks 17 and 32 and postpartum at week 6. Multinomial regression explored associations between maternal variables and infant temperament trajectories at 6 weeks, 12 months, and 18 months. Prenatal anxiety is associated with the high-rising infant difficult temperament trajectory, while prenatal depression/anhedonia is associated with the stable-medium trajectory, attenuated postpartum. Associations between infant temperament and maternal mood depended on timing (pre/postpartum) and symptom type (depression/anhedonia vs. anxiety).     

Synchrony in mother-infant interactions.

A measure of mother-infant synchrony was developed and used to compare the interactions of mothers with preterm and mothers with full-term infants. Each mother-infant dyad was observed during a standard bottle-feeding session on 3 separate occasions: once prior to hospital discharge and 1 and 3 months after discharge. Synchrony, defined by the correlation between mother and infant behavioral rates during corresponding segments of the observation session, was found to (1) distinguish between preterm and full-term groups at 3 months and (2) successfully predict below-average Home Observation for Measurement of the Environment (HOME) scores at 9 months for dyads in which mother and infant behavioral rates were inversely related. Further analysis identified certain interaction characteristics related to synchromy.     

Social support, infant temperament, and parenting self-efficacy: a mediational model of postpartum depression

A model of maternal postpartum depression was tested in which difficult infant temperament was construed as a stressor and supportive interpersonal relationships were construed as a protective resource. It was hypothesized that both infant temperamental difficulty and level of social support would affect maternal depression through the cognitive mediation of perceived self-efficacy in the parenting role. Participants were 55 married women who were assessed during pregnancy and again 3 months postpartum. Infant temperament was assessed through observation, maternal crying records, and the Revised Infant Temperament Questionnaire. Results of a path analysis indicated that infant temperamental difficulty was strongly related to the mothers' level of postpartum depression, both directly and through the mediation of parenting self-efficacy. Consistent with predictions, social support appeared to exert its protective function against depression primarily through the mediation of self-efficacy. Both practical implications for identifying women at risk for postpartum depression and theoretical implications for understanding the mechanisms through which stressful events and social support affect adjustment are discussed.     

The Contribution of Infant, Maternal, and Family Conditions to Maternal Feeding Competencies

OBJECTIVE: Because little is known about the role of family problem-solving processes in the development of mothers' competencies in feeding a very low birth-weight (VLBW) infant, we explored the contribution made by the competence in negotiating displayed by a mother and family member as they jointly problem solve infant-care issues. The infant's neonatal biomedical condition, maternal depressive symptoms, and family poverty status may also contribute to feeding competencies. DESIGN: A sample of 41 mothers of VLBW infants from 2 longitudinal studies who were observed during feeding at 1 and 8 months infant postterm age, with a family member of their choosing, participated in a dyadic problem-solving exercise. We assessed maternal feeding competencies with the Parent-Child Early Relational Assessment (Clark, 1997) and dyadic negotiating competence using an observational scale from the Iowa Family Interaction Rating Scales (Melby & Conger, 2001). We classified infant condition through medical record audit. Maternal depressive symptoms were assessed with the Center for Epidemiologic Studies-Depression (CES-D) Scale (L. S. Radloff, 1977), and family poverty status was determined through the mother's report of family income. RESULTS: Mothers' feeding competencies, structured into 2 factors, Parental Positive Affective Involvement, Sensitivity, and Responsiveness (PPAISR) and Parental Negative Affect and Behavior (PNAB, scored in the direction of low negativity) were stable from 1 to 8 months, accounting for the entire set of predictor variables. Neonatal biomedical condition had no effect on either PPAISR or PNAB; depressive symptoms were negatively associated with PNAB at 8 months; poverty status negatively predicted both PPAISR and PNAB at 1 and 8 months; and negotiating competence of the mother-family member dyad was positively associated with PNAB at 1 month. CONCLUSIONS: Evidence that family poverty status and dyadic negotiating competence were both associated with maternal feeding competencies supports inclusion of these family-level variables in a model of feeding competencies. A mother's negotiating competence with another family member who takes a responsible role in infant care may support maternal feeding competencies during a VLBW infant's early weeks when parenting patterns are forming.     

Activities and Interactions of Mothers and Their Firstborn Infants in the First Six Months of Life: Covariation, Stability, Continuity, Correspondence, and Prediction

Activities of primiparous mothers and infants were observed at 2 and 5 months of age during naturalistic interactions at home. 5 prominent features of mother and infant exchanges in this short-term longitudinal study are described and discussed in the context of 3 models of unique environment-development relations: covariation, stability, continuity, correspondence, and prediction. Generally, mothers' activities did not positively covary at either age, nor did those of infants. Some maternal activities were stable in this time period; some developmentally increased, and some developmentally decreased. Infants' activities were unstable, but most increased over time. Specific mother and infant activities corresponded, and over time mothers and infants influenced one another in specific ways. In the critical period of the first half year, infants appear to be flexible and plastic in their behavioral repertoires and are influenced by their mothers; mothers are somewhat consistent, but they also adapt to the behaviors of their infants.     

Maternal Sleep-Related Cognitions and Infant Sleep: A Longitudinal Study From Pregnancy Through the 1st Year

Infant sleep is a major source of concern for many parents. The aims of this longitudinal study were to assess: (a) the development of sleep patterns among infants, (b) the development of maternal cognitions regarding infant sleep, and (c) the relations between these domains during the 1st year of life. Eighty-five mothers were recruited during pregnancy and completed a questionnaire aimed at assessing maternal sleep-related cognitions. After delivery (at 1, 6, and 12 months) sleep was assessed using actigraphy and sleep logs, and maternal cognitions were reassessed. The findings demonstrated significant predictive and concomitant links between maternal cognitions and infant sleep. Maternal soothing behaviors mediated the relations between these domains.     

A causal analysis relating previous achievement,attitudes, discourse,and intervention to achievement in biology and chemistry

This study described the relationship of 38 variates to achievement in high school biology and chemistry classes. Forty-four teachers prepared audio tape recordings of discussions throughout a nine-month period. Equal-sized groups received treatment consisting of wait time feedback and/or supportive intervention, a form of peer coaching. Other variables were initial measures, which included the variates of class size and previous science grade, pre- and posttest scores on student attitudes and perceptions, and prediscourse and discourse analyses, which included the variates of wait times, actions, and response durations. While previous research has shown that wait time feedback and supportive intervention are effective means of changing teacher behavior, the results of the present study revealed that previous student achievement and the attitudes of students accounted for 70% of the variation in the final examination scores (New York State Regents) on the basis of only the first three weeks of data collection on the variables assessed. Generally, little emphasis on higher-level thinking, wait time, or problem solving was found at the beginning of the school year, and only minimal changes resulted from the application of the treatment variables. Pressures for content coverage and preparation for externally imposed statewide examinations that emphasize memory-level learning augured against the changes that the independent variables were designed to produce.     

Mothers' Physiological and Affective Responding to Infant Distress: Unique Antecedents of Avoidant and Resistant Attachments

In a sample of 127 mother–infant dyads, this study examined the predictive significance of mothers' physiological and observed emotional responding within distressing and nondistressing caregiving contexts at 6 months for infant attachment assessed with Fraley and Spieker's (2003) dimensional approach and the categorical approach at 12 months. Findings revealed that a lesser degree of maternal respiratory sinus arrhythmia withdrawal and higher levels of maternal neutral (vs. positive) affect within distressing (vs. nondistressing) caregiving contexts were distinctive antecedents of avoidance versus resistance assessed dimensionally (but not categorically), independent of maternal sensitivity. Discussion focuses on the usefulness of examining mothers' physiological and affective responding, considering the caregiving context, and employing the dimensional approach to attachment in identifying unique antecedents of patterns of attachment insecurity.     

Risk factors for infant maltreatment: a population-based study

CONTEXT: Of the approximately 900,000 children who were determined to be victims of abuse or neglect by US child protective services in 2002, the birth-to-3 age group had the highest rate of victimization (1.6%) and children younger than 1 accounted for the largest percentage of victims (9.6%). OBJECTIVE: To identify perinatal and sociodemographic risk factors associated with maltreatment of infants up to 1 year of age. DESIGN AND SETTING: Observational cohort study. PARTICIPANTS: 189,055 children born in 1996 in Florida. MAIN OUTCOME MEASURE: Infant maltreatment, defined as a verified report of abuse, neglect, or threatened harm that occurred between day 3 of life and 1 year. RESULTS: 1,602 children (.85%) of the 1996 birth cohort had verified instances of maltreatment by age 1. Of 15 perinatal and sociodemographic variables studied, 11 were found to be significantly related to infant maltreatment. Five factors had adjusted relative risks (RR) of two or greater: Mother smoked during pregnancy (RR 2.8); more than two siblings (RR 2.7); Medicaid beneficiary (RR 2.1); unmarried marital status (RR 2.0); low birth weight infant (RR 2.0). Infants who had four of these five risk factors had a maltreatment rate seven times higher than the population average. CONCLUSIONS: Data on nearly all risk factors found to be significantly associated with infant maltreatment are available on the birth certificate. Such information can be incorporated into a population-based risk-assessment tool that could identify subpopulations at highest risk for infant maltreatment. Because resources are limited, these groups should be given priority for enrollment in child abuse prevention programs.     

A CROSS-NATIONAL COMPARISON OF ACADEMIC AND AFFECTIVE CHARACTERISTICS OF PROSPECTIVE SECONDARY SCHOOL TEACHERS

This research report deals with the measurement of nine groups of prospective secondary teachers; five from the British Isles and four from the United States. The sample of 839 final year, teacher education students was measured on academic achievement, professional education achievement, and affective measures. A multivariate analysis of variance was used to analyze differences between the groups. The analysis resulted in six statistically significant canonical variates. There was a clear country separation on only the first canonical variate, which indicated the British groups high on achievement in English composition and fine arts, and United States groups high on achievement in guidance and measurement. The canonical variates are described in the context of the real variables, as well as the separation of the groups on the canonical variates.     

Secure Base Provision: A New Approach to Examining Links Between Maternal Caregiving and Infant Attachment

This observational study addressed a critical gap in the understanding of the precursors of infant attachment by examining whether a new conceptualization of maternal caregiving behavior, secure base provision (SBP), explained variance in attachment above and beyond variance explained by sensitivity. Participants included 83 low-socioeconomic status (SES), 4.5-month-old infants (56% male) and their mothers. Infant–mother dyads completed laboratory tasks at 4.5 months and three 30-min home visits between 7 and 9 months, then returned to the laboratory at 12 months for an attachment assessment. Maternal sensitivity did not significantly predict infant attachment security. SBP significantly predicted infant attachment, over and above sensitivity, with an effect size eight times larger than that of sensitivity in meta-analytic findings for low-SES families.
