Effects of infant risk status and maternal psychological distress on maternal-infant interactions during the first year of life

ABSTRACT. The associations of infant medical risk, prematurity, and maternal psychological distress with the quality of maternal-infant interactions during the first year of life were evaluated in a prospective, longitudinal follow-up from birth. A total of 103 high-risk very low birth weight (VLBW) infants with bronchopulmonary dysplasia, 68 low-risk VLBW infants without bronchopulmonary dysplasia, and 117 healthy term infants were seen at 1, 8, and 12 months of age. Videotaped feedings at each age were rated using the Nursing Child Assessment Feeding Scale, and mothers completed the Brief Symptom Inventory as a measure of psychological distress. VLBW infant status was related to both maternal and infant behaviors as well as to maternal distress, and these relationships varied with infant age. Overall, VLBW infants displayed fewer responsive, clear interactions, with differences from term infants increasing over time. Maternal distress was related to less cognitive growth fostering for all mothers. Because maternal distress is more prevalent in mothers of VLBW infants postpartum, intervention efforts should focus on assessment of maternal distress and the challenges posed by the interactive behaviors of VLBW infants.

Turn-taking and speech act patterns in the discourse of senile dementia of the Alzheimer's type patients

Conversational discourse patterns of 11 normal elderly and 11 senile dementia of the Alzheimers type (SDAT) patients engaged in dyadic interaction with an examiner were examined. Differences in word usage, turn taking, and speech act production were investigated both for the two-subject groups and for the examiners conversations with each group. Compensatory shifts in discourse by participants are identified. For the subject, differences were shown on words per turn with SDAT subjects speaking in shorter turns and in nonverbal responses with SDAT subjects using this strategy more frequently. Speech act categories of Requestives and Assertives also differed with SDAT subjects using more Requestives and fewer Assertives. The SDAT subjects had significantly more occurrences of unintelligible utterances. For the examiner, words per turn differed with the examiner using shorter turns with SDAT subjects. No differences were shown in the examiners patterns of speech act usage, nonverbal responses, or intelligibility. In general, these results indicate significant discourse differences in the words per turn level for all participants and speech act levels of conversation for SDAT subjects. They also indicate generally maintained interaction patterns by speakers so that the discourse genre of conversation is sustained. The pattern of compensatory shifts in discourse suggests retained flexibility in the communication system of early and mid stage SDAT patients.

Longitudinal Predictors of Maternal Stress and Coping After Very Low-Birth-Weight Birth

OBJECTIVE To determine longitudinal outcomes and contributors to parental stress and coping in mothers of very low-birth-weight (VLBW) children. DESIGN Prospective cohort follow-up of high-risk VLBW children (n = 113), low-risk VLBW children (n = 80), and term children (n = 122) and their mothers from birth to 14 years. SETTING Recruitment from level III neonatal intensive care and term nurseries in a large Midwestern region with follow-up at an academic medical center. PARTICIPANTS A total of 315 mother-infant dyads enrolled from November 8, 1989, to February 22, 1992. MAIN EXPOSURES High-risk VLBW infants had bronchopulmonary dysplasia. Comparison groups were demographically similar low-risk VLBW children (without bronchopulmonary dysplasia) and term children. MAIN OUTCOME MEASURES Child IQ and self-report measures of parenting stress, family impact, maternal coping, education, and social support. RESULTS After VLBW birth, mothers attained fewer additional years of education than term mothers (P = .04). Mothers of high-risk VLBW children felt more personal stress (P = .006) and family stress (P = .009) under conditions of low social support and had greater child-related stress than term mothers; however, they also expressed the highest levels of parenting satisfaction at 14 years. They became less likely to use denial (P = .02) and mental disengagement (P = .03) as coping mechanisms over time. Except for education attainment, mothers of low-risk VLBW infants did not differ from mothers of term children and at 14 years reported the lowest stress. CONCLUSIONS Parenting a VLBW child had both positive and negative outcomes, dependent on child medical risk, child IQ, social support, and maternal coping mechanisms, suggesting that mothers experience posttraumatic growth and resilience after significant distress post partum.

Speech and language outcomes of children with bronchopulmonary dysplasia

UNLABELLED A prospective follow-up of very low birth weight infants (VLBW) with (n = 89) and without (n = 71) bronchopulmonary dysplasia (BPD) and Term control children (n = 93) was conducted at 8 years of age. Groups were compared on measures of articulation, receptive and expressive language, verbal and performance IQ, oral motor skills and gross and fine motor skills. The BPD group demonstrated reduced articulation, receptive language skills, performance IQ, and overall gross and fine motor skills when compared to VLBW and Term groups. The BPD and VLBW groups did not differ on expressive language, oral motor skills, or verbal IQ. The groups also differed in enrollment in special classes and speech-language therapy, with almost half (48%) of the BPD group enrolled in speech-language therapy compared to 21% of the VLBW group, and 9% of the Term group. These results suggest that BPD may have adverse effects on speech development as well as on performance IQ, motor skills, and receptive language over and above the effects of VLBW. LEARNING OUTCOMES (1) As a result of this activity the reader will be able to describe what BPD is and how it impacts speech and language. (2) As a result of this activity the reader will be able to discuss how children with VLBW with BPD differ from children with VLBW without BPD in their developmental outcomes.

During pregnancy, recreational drug-using women stop taking ecstasy (3,4-methylenedioxy-N-methylamphetamine) and reduce alcohol consumption, but continue to smoke tobacco and cannabis: initial findings from the Development and Infancy Study

While recreational drug use in UK women is prevalent, to date there is little prospective data on patterns of drug use in recreational drug-using women immediately before and during pregnancy. A total of 121 participants from a wide range of backgrounds were recruited to take part in the longitudinal Development and Infancy Study (DAISY) study of prenatal drug use and outcomes. Eighty-six of the women were interviewed prospectively while pregnant and/or soon after their infant was born. Participants reported on use immediately before and during pregnancy and on use over their lifetime. Levels of lifetime drug use of the women recruited were high, with women reporting having used at least four different illegal drugs over their lifetime. Most users of cocaine, 3,4-methylenedioxy-N-methylamphetamine (MDMA) and other stimulants stopped using these by the second trimester and levels of use were low. However, in pregnancy, 64% of the sample continued to use alcohol, 46% tobacco and 48% cannabis. While the level of alcohol use reduced substantially, average tobacco and cannabis levels tended to be sustained at pre-pregnancy levels even into the third trimester (50 cigarettes and/or 11 joints per week). In sum, while the use of ‘party drugs’ and alcohol seems to reduce, levels of tobacco and cannabis use are likely to be sustained throughout pregnancy. The data provide polydrug profiles that can form the basis for the development of more realistic animal models.

Coping and Psychological Distress in Mothers of Very Low Birth Weight Young Children

Objective. This study sought to increase understanding of relations among coping strategies, sociodemographic variables, and psychological distress in mothers of high-risk (HR) and low-risk (LR) very low birth weight (VLBW; < 1,500g) infants. Design. The sample (N = 199) consisted of 77 mothers of HR VLBW infants, 43 mothers of LR VLBW infants, and a control group of 79 mothers of healthy, term infants. Data were collected with self-report questionnaires at birth and at 24 months postpartum. Relations among infant medical risk, multiple birth, maternal race, social class, and maternal coping were investigated. Hierarchical regression analyses were used to identify predictors of maternal psychological distress and to determine whether coping differentially moderated maternal psychological distress across groups. Results. Infant medical risk, social support, and maternal coping independently predicted maternal psychological distress. Mothers of HR VLBW infants reported significantly greater psychological distress than mothers of LR VLBW or term infants. Greater use of avoidant and express emotions coping predicted higher psychological distress for all mothers. Greater use of humor coping had a buffering effect, reducing distress only for mothers of HR VLBW infants. Maternal coping scores were related to maternal race and social class, rather than to severity of infant medical risk. Conclusions. Sociocultural sources of resiliency, as well as biological risk factors, should be considered when developing strategies to enhance coping and parenting in HR populations.

One-year outcomes of prenatal exposure to MDMA and other recreational drugs.

OBJECTIVE: A widely used illicit recreational drug among young adults, 3,4-methylenedioxymethamphetamine (MDMA) or ecstasy, is an indirect monoaminergic agonist/reuptake inhibitor affecting the serotonin system. Preclinical studies found prenatal exposure related to long-term learning and memory impairments. There are no studies of sequelae of prenatal MDMA exposure in humans, despite potential harmful effects to the fetus. METHODS: A total of 96 women in the United Kingdom (28 MDMA users; 68 non-MDMA) were interviewed about recreational drug use during pregnancy. Their infants were seen at 12 months using standardized assessments of cognitive, language, and motor development (Preschool Language Scale, Bayley Mental and Motor Development and Behavior Rating Scales [Mental Development Index, Psychomotor Development Index, Behavioral Rating Scale]). Mothers completed the Child Domain Scale of the Parenting Stress Index, The Home Observation of the Environment Scale (in interview), the Brief Symptom Inventory, and the Drug Abuse Screening Test. Women were primarily middle class with some university education, in stable partner relationships, and polydrug users. MDMA and other drug effects were assessed through multiple regression analyses controlling for confounding variables, and analysis of covariance comparing heavier versus lighter and nonexposed groups. RESULTS: Amount of prenatal MDMA exposure predicted poorer infant mental and motor development at 12 months in a dose-dependent manner. Heavily exposed infants were delayed in motor development. Lighter-exposed infants were comparable to nonexposed infants. There were no effects on language, emotional regulation, or parenting stress. CONCLUSIONS: Findings document persistent neurotoxic effects of heavier prenatal MDMA exposure on motor development through the first year of life.

Factor Structure of Coping: Two Studies of Mothers with High Levels of Life Stress.

Exploratory factor analysis (EFA) and confirmatory factor analysis (CFA) were used to investigate the factor structure of coping in mothers with high levels of life stress. In Study 1, EFA of the Coping Orientation to Problems Experienced (C. S. Carver, M. F. Scheier, & J. K. Weintraub, 1989) in a sample of mothers of full-term or very low birth weight 2-year-old children yielded 7 reliable coping factors. Each factor accounted for significant variance in at least 1 of 6 outcomes measuring maternal-child well-being. In Study 2, CFA was used to cross-validate the EFA model on the basis of the responses of mothers of 2-year-old children with prenatal polysubstance exposure. CFA results revealed a moderately good fit, confirming the factor structure in a 2nd, independent sample of mothers with high levels of life stress.

Psychiatric profiles of mothers who take Ecstasy/MDMA during pregnancy: reduced depression 1 year after giving birth and quitting Ecstasy.

Background: The recreational drug MDMA (3,4-methylenedioxymethamphetamine) or ‘Ecstasy’ is associated with heightened psychiatric distress and feelings of depression. The Drugs and Infancy Study (DAISY) monitored the psychiatric symptom profiles of mothers who used Ecstasy/MDMA while pregnant, and followed them over the first year post-partum. Methods: We compared 28 young women whom took MDMA during their pregnancy with a polydrug control group of 68 women who took other psychoactive drugs while pregnant. The Brief Symptom Inventory (BSI) was completed for several periods: The first trimester of pregnancy; and 1, 4 and 12 months after childbirth. Recreational drug use was monitored at each time point. Results: During the first trimester of pregnancy, MDMA-using mothers reported higher depression scores than the polydrug controls. At 1 year after childbirth, their BSI depression scores were significantly lower, now closer to the control group values. At the same time point, their self-reported use of MDMA became nearly zero, in contrast to their continued use of Cannabis/marijuana, nicotine and alcohol. We found significant symptom reductions in those with BSI obsessive-compulsive and interpersonal sensitivity, following Ecstasy/MDMA cessation. Conclusions: The findings from this unique prospective study of young recreational drug-using mothers are consistent with previous reports of improved psychiatric health after quitting MDMA.
