Co-occurring trajectory of housing stability and parenting stress with child behavior problems: A randomized trial of a housing intervention for young mothers experiencing homelessness.

This study examined the effects of an integrative housing intervention (Ecologically Based Treatment, EBT - independent housing and supportive services) on the co-occurring pattern of housing stability and parenting stress among a sample of substance-using mothers who experience homelessness and have young children in their care. The association between the co-occurring patterns of housing stability and parenting stress and child internalizing and externalizing behaviors was also examined. Mothers were randomized to one of the three conditions: EBT (n = 80), Housing-only (HOU; n = 80), or Services as Usual (SAU; n = 80). Follow-up assessments were completed at 3-, 6-, 9-, and 12-months post-baseline. The dual-trajectory latent class growth analyses identified five subgroups of co-occurring patterns: low-greatly improved housing paired with moderate-improved parenting stress, low-greatly improved housing paired with high-improved parenting stress, low-moderately improved housing paired with moderate-static parenting stress, low-worse housing paired with moderate-improved parenting stress, and low-worse housing paired with high-static parenting stress. Findings showed that EBT was more effective in improving housing stability and reducing parenting stress compared to HOU and SAU conditions, and further, HOU was more effective than SAU. Additionally, children whose mothers reported increased housing stability together with improved parenting stress had lower levels of internalizing and externalizing behaviors. The findings provide support to the efficacy of EBT in increasing housing stability and reducing parenting stress. The observed improvements subsequently benefited children's behavioral outcomes.

Emotion dysregulation and reward responsiveness as predictors of autonomic reactivity to an infant cry task among substance-using pregnant and postpartum women.

Maternal substance use may interfere with optimal parenting, lowering maternal responsiveness during interactions with their children. Previous work has identified maternal autonomic nervous system (ANS) reactivity to parenting-relevant stressors as a promising indicator of real-world parenting behaviors. However, less is known about the extent to which individual differences in emotion dysregulation and reward processing, two mechanisms of substance use, relate to maternal ANS reactivity in substance-using populations. The current study examined associations among emotion dysregulation, reward responsiveness, and ANS reactivity to an infant cry task among 77 low-income and substance-using women who were either pregnant (n=63) or postpartum (n=14). Two indicators of ANS functioning were collected during a 9min computerized infant cry task (Crybaby task): respiratory sinus arrhythmia (RSA) and pre-ejection period. Mothers also completed self-reported measures of emotion dysregulation and reward responsiveness. Analyses revealed that trait emotion regulation was associated with RSA reactivity to the Crybaby task, such that greater emotion dysregulation was associated with greater RSA reduction during the infant cry task than lower emotion dysregulation. Reward responsiveness was not significantly associated with either indicator of ANS reactivity to the task. Findings revealed distinct patterns of associations linking emotion dysregulation with ANS reactivity during a parenting-related computerized task, suggesting that emotion regulation may be a key intervention target for substance-using mothers.

Nutrient Supplementation during the Prenatal Period in Substance-Using Mothers: A Narrative Review of the Effects on Offspring Development.

Substance use during pregnancy increases the risk for poor developmental outcomes of the offspring, and for substance-dependent mothers, abstaining from substance use during pregnancy is often difficult. Given the addictive nature of many substances, strategies that may mitigate the harmful effects of prenatal substance exposure are important. Prenatal nutrient supplementation is an emerging intervention that may improve developmental outcomes among substance-exposed offspring. We provide a narrative review of the literature on micronutrient and fatty acid supplementation during pregnancies exposed to substance use in relation to offspring developmental outcomes. We first discuss animal models exposed to ethanol during pregnancy with supplementation of choline, zinc, vitamin E, iron, and fatty acids. We follow with human studies of both alcohol- and nicotine-exposed pregnancies with supplementation of choline and vitamin C, respectively. We identified only 26 animal studies on ethanol and 6 human studies on alcohol and nicotine that supplemented nutrients during pregnancy and reported offspring developmental outcomes. There were no studies that examined nutrient supplementation during pregnancies exposed to cannabis, illicit substances, or polysubstance use. Implementations and future directions are discussed.

Prenatal Reflective Functioning as a Predictor of Substance-Using Mothers' Treatment Outcome: Comparing Results From Two Different RF Measures.

Mothers with prenatal substance use disorder (SUD) often show broad deficits in their reflective functioning (RF), implying severe risk for the relationship with their baby. Two different types of prenatal maternal RF may be important for parenting: adult attachment-focused-RF (AAI-RF), regarding parent's own childhood experiences, and parenting-focused RF (PRF) regarding their own current process of becoming a parent. However, their inter-relations and potentially different roles for parenting intervention outcomes are not clear. This study examined the associations between mothers' prenatal AAI-RF and pre- and post-natal PRF, and their role in mother-infant interaction and substance use as treatment outcomes. The participants were 57 treatment-enrolled pregnant mothers with SUD and 50 low-risk comparison mothers. AAI-RF was measured with the Adult Attachment Interview. For a subsample of 30 mothers with SUD, PRF was measured with Pregnancy Interview (during pregnancy/pre-intervention), and with Parent Development Interview at 4 months (during intervention). Mother-infant interaction was measured with Emotional Availability Scales at 4 and 12 months (post-intervention), and maternal substance use by post-natal substance relapses. Prenatal AAI-RF and pre- and post-natal PRF were highly associated with each other. Only higher prenatal PRF predicted better mother-infant interaction quality at 4 months and less substance use during the child's first year. Interestingly, prenatal PRF and AAI-RF predicted opposite changes in mother-infant interaction: lower prenatal PRF, but higher AAI-RF predicting more positive change. AAI-RF was especially associated with a change in maternal intrusiveness and hostility, indicating that it represents a more general regulatory tendency. Further studies are needed in larger and lower-risk samples. Our results suggest, however, that AAI-RF and PRF are partially distinct and should be uniquely targeted in perinatal interventions.

Exploring resting frontal EEG and reflective functioning in maternal substance use.

Maternal substance use is associated with altered neural activity and poor offspring outcomes, which may be facilitated by suboptimal caregiving in the form of impaired parental reflective functioning (PRF). To investigate these associations, the resting-state frontal electroencephalography (EEG) power of 48 substance-using mothers and 37 non-substance-using mothers were examined, specifying seven frequency bands: delta, theta, alpha, alpha1, alpha2, beta, and gamma. Substance-using mothers exhibited enhanced beta and gamma spectral power compared to non-substance-using mothers, potentially reflecting higher arousal states in substance-using mothers. There were no between-group differences in any component of PRF (i.e., levels of pre-mentalizing, certainty, and interest and curiosity). Whole-sample analyses revealed significant positive correlations between pre-mentalizing and delta spectral power. Taken together, these findings suggest potential neural correlates of maternal substance use and PRF, providing an important next step into examining associations between maternal substance use and poor child outcomes.

The Negative Impact of Maternal Perinatal Opioid Use on Neonatal Outcomes.

Objective: To compare outcomes among newborns of opioid-using and nonopioid drug-using mothers with those of control mothers who did not report substance use.Methods: Using the Rochester Epidemiology Project, newborns diagnosed with drug withdrawal syndrome (per ICD-9 or ICD-10 codes) from January 2010 through June 2017 were identified. For mothers, data collected included age, race, drug use, number of prenatal visits, and results of the urinary drug abuse survey, meconium test, and self-report survey. Demographic and perinatal data collected for newborns included birth date; sex; Apgar scores at 1, 5, and 10 minutes; neonatal intensive care stay; and vital status. Controls (n = 771) were similarly selected in regard to sex, birth date, and county.Results: Of 328 infants identified, 168 were born with opioid neonatal abstinence syndrome and 160 with a nonopioid withdrawal syndrome. Control mothers had more prenatal visits than mothers in the nonopioid and opioid groups. Newborns of control mothers had higher Apgar scores at 1 and 5 minutes than both substance-using groups. Opioid-using mothers were almost twice as likely to have newborns requiring intensive care and 3 times as likely to use benzodiazepines compared to the other substance-using mothers. Substance-using mothers had more premature babies than controls.Conclusions: Prenatal opioid use is a substantial risk factor for prematurity. Newborns diagnosed with neonatal abstinence syndrome are at risk of perinatal complications. Mothers using opioids during pregnancy also tend to use other substances. Longitudinal research should clarify how prenatal substance use interacts with other risk factors during a child's first years.

Maternal pre- and postnatal substance use and attachment in young children: A systematic review and meta-analysis.

Maternal substance use has often been associated with insecure and disorganized child attachment. We evaluated this association with a meta-analysis of young children and, further, systematically reviewed mediating and moderating factors between maternal substance use and child attachment. We performed a systematic database search of quantitative English language studies on child attachment that included substance-using mothers and their children below 6 years of age. Eleven studies (N = 1,841) met the inclusion criteria and were included in the meta-analysis of attachment security and seven (N = 1,589) studies were included in the meta-analysis of attachment disorganization. We found that maternal substance use was negatively associated with secure attachment in children, but the effect size was small (r = -.10). The association with disorganized attachment was not significant (r = .15). Related to moderating and mediating factors (k = 6), we found evidence on the role of teratogenic and sociological factors on child attachment. Most importantly, the impact of cumulative risks was vital. However, literature was scarce, and studies varied in risk of bias, leaving many unanswered questions on other potential factors underlying the development of attachment in these high-risk children. We discuss the results considering clinical implications and future directions.

Engaging Mothers to Implement Nonpharmacological Care for Infants With Neonatal Abstinence Syndrome: Perceptions of Perinatal and Pediatric Nurses.

Little is known about nurse perceptions regarding engagement of mothers in implementation of nonpharmacological care for opioid-exposed infants. This study was designed to describe perinatal and pediatric nurse perceptions of (1) engaging mothers in the care of opioid-exposed infants and (2) facilitators and barriers to maternal engagement. This study used a qualitative descriptive design to interview perinatal and pediatric nurses in one Midwest United States hospital. Interviews were conducted via telephone using a semistructured interview guide and audio recorded. Audio files were transcribed verbatim and thematically analyzed using the constant comparative method. Twenty-one nurses participated in the study, representing a family birth center, neonatal intensive care unit, and pediatric unit. Five major themes resulted from analysis: (1) vulnerability and bias; (2) mother-infant care: tasks versus model of care; (3) maternal factors affecting engagement and implementation; (4) nurse factors affecting engagement and implementation; and (5) recommendations and examples of nursing approaches to barriers. Minor themes supported each of the major themes. Nurses must engage mothers with substance use histories with empathy and nonjudgment, identify and promote maternal agency to care for their infants, and engage and activate mothers to deliver nonpharmacological care during the hospital stay and following discharge. Findings suggest interventions are needed to improve (1) nursing education regarding maternal substance use and recovery, (2) empathy for substance-using mothers and mothers in treatment, and (3) identification and support of maternal agency to provide nonpharmacological care to withdrawing infants.

Substance use and mothers' neural responses to infant cues.

Substance use may influence mothers' responsiveness to their infants and negatively impact the parent-infant relationship. Maternal substance use may co-opt neural circuitry involved in caregiving, thus reducing the salience of infant cues and diminishing the sense of reward experienced by caring for infants. Gaps in understanding exist with regard to the mechanisms by which substance use operates to influence mothers' processing of infant cues and how this translates to caregiving. Therefore, we examined how substance use might relate to maternal neural responses to infant cues using event-related potentials (ERPs). Substance-using (n=29) and nonsubstance-using (n=29) mothers viewed photographs of infant faces and heard recordings of infant vocalizations while electroencephalography was recorded simultaneously. Three specific ERP components were used to examine initial processing of infant faces (N170) and cries (N100), and attentional allocation to infant faces and cries (P300). Substance-using mothers did not discriminate facial affect at early encoding stages (N170), were generally slower to orient to infant cries (N100), showed heightened responses to neutral faces (P300), and failed to adaptively differentiate between high-distress versus low-distress cries (P300). These differences may be important to caregiving behaviors associated with the formation of mother-child attachment. Implications are discussed, as are limitations and future directions.

Differential responses to infant faces in relation to maternal substance use: An exploratory study

BackgroundMaternal substance use and addiction has been associated with negative consequences for parenting and may increase addiction vulnerability in the developing child. Neuroimaging research suggests that substance use may decrease the reward of caring for infants and heighten stress reactivity to affective infant cues. MethodsThirty-two substance-using mothers and twenty-two non-substance-using mothers were presented with emotional face and cry stimuli generated from their own and a demographically matched unknown infant during fMRI scanning. Between-group differences in neural activity during task performance were assessed using whole-brain, mixed-effects models corrected for multiple comparisons (voxel-level p < 0.001, pFWE<0.05). ResultsRelative to non-substance-using mothers, substance-using mothers exhibited greater activation when viewing their own infant’s face as compared to an unknown infant’s face across multiple brain regions, including superior medial frontal, inferior parietal, and middle temporal regions. Substance-using mothers also had a decreased response to sad infant faces in the ventral striatum relative to the non-substance-using mothers. Neural responses to own vs. unknown infant cries did not significantly differ between substance-using and non-substance-using mothers. ConclusionsFindings suggest overlapping cortical and subcortical brain regions implicated in responding to infant faces, with activation differences related to infant familiarity, emotional expression, and maternal substance use. While prior work has focused on attenuated neural responses to infant cues, greater attention is needed toward understanding the increased reactivity to affective infant cues observed in substance-using mothers.

Short-term health outcomes of newborn infants of substance-using mothers in Australia and New Zealand: A systematic review.

Substance use is not unusual among women of childbearing age. Pregnant women who use a substance and the consequent impacts on a newborn vary across studies and settings. We reviewed New Zealand and Australian literature to examine the short-term health outcomes of newborn of substance-using mothers and their demographic characteristics. Five medical/nursing databases and google scholar were searched in April 2017. Studies were considered eligible if they described outcomes of newborn of substance-using mothers. Mixed Methods Appraisal Tool was used for quality assessment of candidate studies. Relevant data were extracted and analyzed using narrative synthesis. Based on data availability, a subset of studies was included in meta-analysis. Although findings of individual studies vary, there are some evidence that the infants born to substance-using mothers were likely to have preterm birth, low birthweight, small-for-gestational age, low Apgar score, and admission to neo-natal intensive care unit. The likelihood of adverse health outcomes was much higher for newborns of polysubstance-using mothers, than newborns of mothers using a single substance. Pregnant women who use illicit substance are predominantly socially disadvantaged, in their twenties and or of Aboriginal descent. Infants of substance-using mothers suffer a range of adverse health outcomes. Multidisciplinary and integrated approach of services that ensure supportive social determinants of health may result in a better outcome for newborn and positive behavioral change among mothers.

Family systems therapy for substance-using mothers and their 8- to 16-year-old children.

Family systems therapy has shown to be a powerful adjunct to substance use treatment for couples and for adolescent substance users (Rowe, 2012). However, studies including children (8-16 years of age) in the treatment of their substance using mothers have been overlooked and are essentially nonexistent. Addressing the quality of the mother-child relationship and communication through family systems therapy may prove to be a potent intervention focus for improving mothers' substance use outcomes and parent-child interaction. As such, the current study recruited 183 mothers who sought outpatient treatment through a local substance use treatment facility and randomly assigned them to also receive family systems therapy or Women's Health Education. Self-report and observational data were collected, and assessment interviews were completed at baseline and 3, 6, 12, and 18 months postbaseline. Findings showed that women assigned to family systems therapy showed a quicker decline in alcohol, marijuana, and cocaine use, supporting the efficacy of family therapy as an important addition to mother's substance use treatment plans. Data also revealed an association between change in observed autonomy-relatedness and substance use, though mediation was not found. To our knowledge this is the first effort to successfully document a family systems therapy for substance using mothers with minor children in their care. (PsycINFO Database Record

Pregnant women and substance use: fear, stigma, and barriers to care

BackgroundSubstance use during pregnancy and motherhood is both a public health and criminal justice concern. Negative health consequences associated with substance use impact both the mother and the developing fetus, and there are ongoing attempts to criminalize substance use during pregnancy that put pregnant substance-using women at risk of detection, arrest, and punishment. This study explored the experiences of substance-using mothers as they navigated health and criminal justice consequences and accessed needed resources in the community.MethodsIn-depth life history interviews were conducted with 30 recently-pregnant women who had used alcohol or other drugs during their pregnancies. The three-part interview schedule included questions about past and current substance use, life history, and experiences with criminal justice authorities, child protective services, and health professionals.ResultsWomen’s stories highlighted their strategies for managing their risk of detection by health or criminal justice authorities, including isolating themselves from others, skipping treatment appointments, or avoiding treatment altogether. Women described multiple barriers to treatment and healthcare, including a lack of suitable treatment options and difficulty finding and enrolling in treatment.ConclusionThe findings suggest that policies that substance-using women find threatening discourage them from seeking comprehensive medical treatment during their pregnancies. The implications of the findings are discussed, particularly the need for further expansion of treatment programs and social services to meet the needs of substance-using women.

In search of neural endophenotypes of postpartum psychopathology and disrupted maternal caregiving.

This is a selective review that provides the context for the study of perinatal affective disorder mechanisms and outlines directions for future research. We integrate existing literature along neural networks of interest for affective disorders and maternal caregiving: (i) the salience/fear network; (ii) the executive network; (iii) the reward/social attachment network; and (iv) the default mode network. Extant salience/fear network research reveals disparate responses and corticolimbic coupling to various stimuli based upon a predominantly depressive versus anxious (post-traumatic stress disorder) clinical phenotype. Executive network and default mode connectivity abnormalities have been described in postpartum depression (PPD), although studies are very limited in these domains. Reward/social attachment studies confirm a robust ventral striatal response to infant stimuli, including cry and happy infant faces, which is diminished in depressed, insecurely attached and substance-using mothers. The adverse parenting experiences received and the attachment insecurity of current mothers are factors that are associated with a diminution in infant stimulus-related neural activity similar to that in PPD, and raise the need for additional studies that integrate mood and attachment concepts in larger study samples. Several studies examining functional connectivity in resting state and emotional activation functional magnetic resonance imaging paradigms have revealed attenuated corticolimbic connectivity, which remains an important outcome that requires dissection with increasing precision to better define neural treatment targets. Methodological progress is expected in the coming years in terms of refining clinical phenotypes of interest and experimental paradigms, as well as enlarging samples to facilitate the examination of multiple constructs. Functional imaging promises to determine neural mechanisms underlying maternal psychopathology and impaired caregiving, such that earlier and more precise detection of abnormalities will be possible. Ultimately, the discovery of such mechanisms will promote the refinement of treatment approaches toward maternal affective disturbance, parenting behaviours and the augmentation of parenting resiliency.

An overview of clinical tools used to assess neonatal abstinence syndrome.

Several clinical tools have been developed to quantify the severity of withdrawal signs and symptoms exhibited by infants born to substance-using mothers. Scores from the systematic assessments are used to guide treatment of infants with moderate to severe clinical signs. This article provides an overview of published assessment tools developed for infants with neonatal abstinence syndrome. Nurses caring for infants at risk for neonatal abstinence syndrome should be knowledgeable about the tools used to evaluate these infants and guide their treatment. The ideal assessment tool should be published and include item definitions and a protocol for administering the tool. Nurses need education and training to achieve competency and interobserver reliability in the use of a selected tool. Tool-specific materials should be used to standardize training and improve accuracy in assessments. Competent and knowledgeable nurses play a critical role in improving outcomes for infants with neonatal abstinence syndrome.

The nature and extent of child protection involvement among heroin-using mothers in treatment: high rates of reports, removals at birth and children in care.

A substantial proportion of women in treatment for substance use problems are mothers of dependent children, but only a small number of studies have explored the nature and extent of their child protection involvement with substance-using mothers themselves. A large sample of mothers on the opioid treatment program (OTP) in Sydney, Australia, were interviewed. This paper describes their characteristics, the extent and nature of their involvement with the child protection system, the parenting-related interventions provided and their views of their own parenting. The 171 mothers were disadvantaged and marginalised and had 302 children under the age of 16 years, 99 of whom were in out-of-home care. Nearly half the children in care (n = 42) had been removed at the time of their birth, and half (n = 49) had been removed from a mother who was on an OTP at the time. Among the younger children (age 1-2 years), higher proportions had been removed at birth than among the older children. None of the 32 mothers who had a child removed at birth and then gave birth subsequently retained care of their new baby. Women often chose to enter treatment (63.6%) for child-related reasons (35%) and attempted to shield their children from their substance use. Few health services were provided to them outside the availability of OTP. Entering treatment presents an opportunity for improving outcomes for these women and their children and to reduce future involvement with the child protection system.

Papanicoloau smear uptake among substance-using mothers in Western Australia

Background: Papanicoloau (Pap) smear screening has helped to reduce cervical cancer rates significantly through the detection of premalignant cells ( Bray et al, 2005 ). Uptake among women who use alcohol and other drugs (AOD) is known to be low ( Chau et al, 2002 ) so they are at increased risk of being under-represented in the adequately screened population. AOD-using women experience disproportionately increased morbidity and mortality from cervical dysplasia and cancer ( Nogara et al, 2013 ). Pregnancy may provide the midwife an opportunity to offer this vital screening test. Objective: The audit investigated Pap smear uptake and results among AOD-using pregnant women. Setting: Pregnant women cared for by an obstetric AOD service based in a tertiary hospital in Perth, Western Australia, were eligible for inclusion in the study. Results: Across a period of 12 months, 333 childbearing-aged AOD-addicted women were audited: 142 had a Pap smear in the previous 3 years; 80 had not had a Pap smear in the previous 3 years; 80 declined a Pap smear; and 31 were either illegible or no record was available. Conclusion: This audit emphasises the importance of Pap smears being offered and followed up among the population of AOD-using pregnant mothers. Encouraging early booking and access to early antenatal care with midwives who are proficient in Pap smear collection is essential in order to provide optimal care.

African American Adolescents' Interactions with Their Substance-Using Mothers

Understanding the interactions that African American youth have with their substance-using mothers is important because of the increased likelihood that these youth depend on their mothers as their primary providers. In-depth interviews were conducted with 14 urban-dwelling, African American adolescents with substance-using mothers to explore the nature of their interactions. Youth report maternal influence on their attitudes in general and toward child-rearing and peer group affiliations. Communication between the dyads is often strained and youth assume roles of sibling protector and maternal confidant. Youth have supportive adults in their lives but their engagement with these supports is also shaped by maternal substance use. Implications for how direct practice with youth might address these outcomes are discussed.

Mothers in methadone treatment and their involvement with the child protection system: A replication and extension study

ObjectivesAlthough a high level of involvement with the child protection system has been identified in families where parental substance use is a feature, not all such parents abuse or neglect their children or have contact with the child protection system. Identifying parents with substance-use histories who are able to care for their children without intervention by the child protection system, and being able to target interventions to the families who need them the most is important. This study interviewed a relatively large sample of mothers about their histories, their children and their involvement with the child protection system. We hypothesized that mothers in opioid pharmacological treatment who are involved with child protection services are different in characteristics to those mothers who are not involved. MethodsOne hundred and seventy-one women, with at least one child aged under 16 years, were interviewed at nine treatment clinics providing pharmacological treatment for opioid dependence across Sydney, Australia. ResultsJust over one-third of the women were involved with child protection services at the time of interview, mostly with children in out-of-home care. Logistic regression analyses revealed that factors which significantly increased the likelihood of the mother being involved with the child protection system were: (1) having a greater number of children, (2) being on psychiatric medication, and (3) having less than daily contact with her own parents. ConclusionsThis study replicates and extends the work of Grella, Hser, and Huang (2006) and the limited literature published to date examining the factors which contribute to some substance-using mothers becoming involved with the child protection system while others do not. The finding that mental health problems and parental supports (along with the number of children) were significantly associated with child protection system involvement in this study, indicates a need for improved interventions and the provision of treatment and support services if we are to reduce the involvement of the child protection system with these families.
