Behavioral and emotional problems among children of cocaine- and opiate-dependent parents

Systematic Review and Meta-analysis of the Relationship Between Exposure to Parental Substance Use and Attention-Deficit/Hyperactivity Disorder in Children

Attention-deficit/hyperactivity disorder (ADHD) is characterized by persistent patterns of inattention, hyperactivity, and impulsiveness. Among US children and adolescents aged 3-17 years, 9.4% have a diagnosis of ADHD. Previous research suggests possible links between parental substance use and ADHD among children. We conducted a systematic review and meta-analysis of 86 longitudinal or retrospective studies of prenatal or postnatal alcohol, tobacco, or other parental substance use and substance use disorders and childhood ADHD and its related behavioral dimensions of inattention and hyperactivity-impulsivity. Meta-analyses were grouped by drug class and pre- and postnatal periods with combined sample sizes ranging from 789 to 135,732. Prenatal exposure to alcohol or tobacco and parent substance use disorders were consistently and significantly associated with ADHD among children. Other parental drug use exposures resulted in inconsistent or non-significant findings. Prevention and treatment of parental substance use may have potential for impacts on childhood ADHD.

Co-Occurring Trajectory of Mothers' Substance Use and Psychological Control and Children's Behavior Problems: The Effects of a Family Systems Intervention

This study examined the effects of a family systems therapy (Ecologically-Based Family Therapy [EBFT]) on the co-occurring trajectory of mothers' substance use and psychological control, and its association with children's problem behaviors. Participants included 183 mothers with a substance use disorder who had at least one biological child in their care. Mothers were randomly assigned to one of the three intervention conditions: EBFT-home, n = 62; EBFT-office, n = 61; or Women's Health Education, n = 60. Participants were assessed at baseline, 3, 6, 12, and 18 months post-baseline. A dual-trajectory class growth analysis identified three groups of mothers in regard to their change trajectories. The majority of the mothers exhibited a synchronous decrease in substance use and psychological control (n = 107). In all, 46 mothers exhibited a synchronous increase in substance use and psychological control. For the remaining 30 mothers, substance use and psychological control remained stable. Mothers in the family therapy condition were more likely to show reduced substance use and psychological control compared to mothers in the control condition. Moreover, children with mothers who showed decreased substance use and psychological control exhibited lower levels of problem behaviors compared to children with mothers showing increased substance use and psychological control. The findings provide evidence for the effectiveness of family systems therapy, EBFT, in treating mothers' substance use, improving parenting behaviors, and subsequently improving child behavioral outcomes.

Exposure to Medication Overdose as an Adversity in Childhood

PURPOSE

To determine the prevalence of youth exposure to medication or pill overdose by someone close to them, as well as how common this is within the spectrum of major stressful events and child victimization experienced by youth.

DESIGN AND METHODS

Data were collected as part of the Third National Survey of Children's Exposure to Violence, a nationally representative telephone survey of youth, ages 2-17years (N=3738) conducted in 2013. The analytical subset for the current paper is youth ages 10-17years (n=1959).

RESULTS

Estimates indicate that approximately 1 in 12 youth (8%), ages 10-17 have been exposed to medication overdose by someone close to them in their lifetimes. Overdose exposure is related to recent trauma symptoms, alcohol and other substance use. However, these relationships appear to be largely driven by the co-existence of major stressful events these youth are experiencing. Alcohol use is the exception; exposure to medication overdose continues to be related to past year personal alcohol use even after adjusting for other lifetime stressful events.

CONCLUSIONS

Having a close family member or friend overdose on a medication is a common experience among U.S. youth and related to high rates of co-occurring stressful events.

PRACTICE IMPLICATIONS

Health care providers should be aware that youth exposure to medication overdoses likely indicates exposure to other recognized adversities. Youth with a caregiver who has had an overdose may require an urgent response including referral to crisis intervention through child and family services.

The association between parental history and delay discounting among individuals in recovery from addiction

BACKGROUND

Family history of addiction is a risk factor for substance use disorders. Delay discounting (DD) is associated with the risk of substance use and dependence, and is predictive of the likelihood of successful abstinence and treatment outcomes; thus, we investigated the extent to which having parents with addiction (parental history of addiction) and number of addicted parents affect DD among individuals in recovery from addiction.

METHODS

Data from 177 individuals in recovery from addiction from The International Quit and Recovery Registry (IQRR), an ongoing online data collection program that aims to understand addiction and how people succeed in recovery, were included in the analysis. Participants with no, one, or two parents with addiction were compared on measures of DD using an adjusting-amount task.

RESULTS

Parental history of addiction was significantly associated with delay discounting. After controlling for age and gender, which were significantly different between groups, participants reporting two biological parents with addiction had significantly higher DD rates compared to those reporting one or no parents with addiction.

CONCLUSIONS

Participants with two parents with addiction had significantly higher rates of discounting compared to those with no or only one parent with addiction. This information can serve as a foundation to better identify and target important subgroups that need additional or non-traditional intervention strategies to address their larger degree of impulsivity and help maintain abstinence or achieve better treatment outcomes.

Acceptability of aggression among children who reside with substance-abusing parents: The influence of behavioral dysregulation, exposure to neighborhood violence, and interparental violence

The present study examined how interparental violence, neighborhood violence, behavioral regulation during parental conflict, and age predicted beliefs about the acceptability of aggression and the acceptance of retaliation against an aggressive peer among youths. Participants were 110 families (mothers, fathers, and children) in which one or both parents met criteria for substance use disorder. Results of a bootstrapped path model revealed higher exposure to neighborhood violence predicted greater acceptability of general aggression, whereas higher father-to-mother violence perpetration predicted lower acceptability of general aggression. Higher exposure to neighborhood violence, behavioral dysregulation during parental conflict, and older child age predicted greater approval of retaliation toward an aggressive peer. Findings are interpreted as related to the cognitive-contextual framework.

Criminally Involved Parents Who Misuse Substances and Children's Odds of Being Arrested as a Young Adult: Do Drug Treatment Courts Mitigate the Risk?

This paper examined (1) the association between parents who are convicted of a substance-related offense and their children's probability of being arrested as a young adult and (2) whether or not parental participation in an adult drug treatment court program mitigated this risk. The analysis relied on state administrative data from North Carolina courts (2005-2013) and from birth records (1988-2003). The dependent variable was the probability that a child was arrested as a young adult (16-21). Logistic regression was used to compare groups and models accounted for the clustering of multiple children with the same mother. Findings revealed that children whose parents were convicted on either a substance-related charge on a non-substance-related charge had twice the odds of being arrested as young adult, relative to children whose parents had not been observed having a conviction. While a quarter of children whose parents participated in a drug treatment court program were arrested as young adults, parental completion this program did not reduce this risk. In conclusion, children whose parents were convicted had an increased risk of being arrested as young adults, irrespective of whether or not the conviction was on a substance-related charge. However, drug treatment courts did not reduce this risk. Reducing intergenerational links in the probability of arrest remains a societal challenge.

Child Abuse and Mental Disorders in Iranian Adolescents

Background

Child abuse is a serious social health problem all over the world with important adverse effects.

Objectives

The aim of this study was to extend our understanding of the relation between mental disorders and child abuse.

Materials and Methods

The study was designed as a cross-sectional survey on 700 students in secondary schools using multiple cluster sampling in Yazd, Iran in 2013. We applied 2 self reported questionnaires: DASS (depression anxiety stress scales)-42 for assessing mental disorders (anxiety, stress and depression) and a standard self-reported valid and reliable questionnaire for recording child abuse information in neglect, psychological, physical and sexual domains. The collected data was analyzed using SPSS software. P-values < 0.05 were considered as significant.

Results

There was a statically significant correlation between mental disorder and child abuse score (Spearman rho: 0.2; P-value < 0.001). The highest correlations between mental disorders and child abuse were found in psychological domain, Spearman’s rho coefficients were 0.46, 0.41 and 0.36 for depression, anxiety and stress respectively (P-value < 0.001). Based on the results of logistic regression for mental disorder, females, last born adolescents and subjects with drug or alcohol abuser parents had mental disorder odds of 3, 0.4 and 1.9 times compared to others; and severe psychological abuse, being severely neglected and having sexual abuse had odds 90, 1.6 and 1.5 respectively in another model.

Conclusions

Programming for mandatory reporting of child abuse by physicians and all health care givers e.g. those attending schools or health centers, in order to prevent or reduce its detrimental effects is useful and success in preventing child abuse could lead to reductions in the prevalence of mental disorders.

Intergenerational effects of parental substance-related convictions and adult drug treatment court participation on children's school performance

This study examined the intergenerational effects of parental conviction of a substance-related charge on children's academic performance and, conditional on a conviction, whether completion of an adult drug treatment court (DTC) program was associated with improved school performance. State administrative data from North Carolina courts, birth records, and school records were linked for 2005-2012. Math and reading end-of-grade test scores and absenteeism were examined for 5 groups of children, those with parents who: were not convicted on any criminal charge, were convicted on a substance-related charge and not referred by a court to a DTC, were referred to a DTC but did not enroll, enrolled in a DTC but did not complete, and completed a DTC program. Accounting for demographic and socioeconomic factors, the school performance of children whose parents were convicted of a substance-related offense was worse than that of children whose parents were not convicted on any charge. These differences were statistically significant but substantially reduced after controlling for socioeconomic characteristics; for example, mother's educational attainment. We found no evidence that parent participation in an adult DTC program led to improved school performance of their children. While the children of convicted parents fared worse on average, much--but not all--of this difference was attributed to socioeconomic factors, with the result that parental conviction remained a risk factor for poorer school performance. Even though adult DTCs have been shown to have other benefits, we could detect no intergenerational benefit in improved school performance of their children.

Effects of prenatal substance exposure on infant temperament vary by context

This was a prospective longitudinal multisite study of the effects of prenatal cocaine and/or opiate exposure on temperament in 4-month-olds of the Maternal Lifestyle Study (N = 958: 366 cocaine exposed, 37 opiate exposed, 33 exposed to both drugs, 522 matched comparison). The study evaluated positivity and negativity during The Behavior Assessment of Infant Temperament (Garcia Coll et al., 1988). Parents rated temperament (Infant Behavior Questionnaire; Rothbart, 1981). Cocaine-exposed infants showed less positivity overall, mainly during activity and threshold items, more negativity during sociability items, and less negativity during irritability and threshold items. Latent profile analysis indicated individual temperament patterns were best described by three groups: low/moderate overall reactivity, high social negative reactivity, and high nonsocial negative reactivity. Infants with heavy cocaine exposure were more likely in high social negative reactivity profile, were less negative during threshold items, and required longer soothing intervention. Cocaine- and opiate-exposed infants scored lower on Infant Behavior Questionnaire smiling and laughter and duration of orienting scales. Opiate-exposed infants were rated as less respondent to soothing. By including a multitask measure of temperament we were able to show context-specific behavioral dysregulation in prenatally cocaine-exposed infants. The findings indicate flatter temperament may be specific to nonsocial contexts, whereas social interactions may be more distressing for cocaine-exposed infants.

"The Whole Family Suffered, so the Whole Family Needs to Recover": Thematic Analysis of Substance-Abusing Mothers' Family Therapy Sessions

Substance abusing mothers and their children are more likely to experience a range of social, behavioral, and psychological difficulties. Despite the significant challenges faced by these families, little is known about their experiences in treatment. The current study analyzed 12 sessions of family therapy using thematic analysis to identify common themes that arose during substance abusing mothers and their children's discussion during family therapy. Mothers' ages ranged from 28 to 35 years and the children's ages ranged from 12 to 14 years. Four therapy sessions from three families were coded for a total of 12 therapy sessions. An ecological framework was used to classify themes, in which themes related to each level of the families' ecological systems were identified. Thematic analysis of the therapy sessions indicated that mothers and their children primarily discussed topics related to their relational and emotional needs. The findings indicated that substance use disordered mothers and their children have unique treatment needs that should be addressed when the mother seeks treatment. More research is needed to further clarify and confirm the observations in this study. In particular, future research should include a larger sample and quantitative methodology.

Blunted Heart Rate Response as a Potential Endophenotype of Substance Use Disorders: Evidence from High-Risk Youth

BACKGROUND

Children of parents with a substance use disorder (CPSUD) are at increased risk for developing problematic substance use later in life. Endophenotypes may help to clarify the mechanism behind this increased risk. However, substance use and externalizing symptoms may confound the relation between dysregulated physiological stress responding and familial risk for substance use disorders (SUDs).

METHODS

We examined whether heart rate (HR) responses differed between CPSUDs and controls. Participants (aged 11-20 years) were CPSUDs (N = 75) and controls (N = 363), semi-matched on the basis of sex, socioeconomic status, and ethnicity. HR was measured continuously during a psychosocial stress procedure. Substance use and externalizing symptoms were self-reported and mother-reported, respectively.

RESULTS

A piecewise, mixed-effects model was fit for HR across the stress procedure, with fixed effects for HR reactivity and HR recovery. CPSUDs showed a blunted HR recovery. CPSUDs reported drinking more frequently, were more likely to use tobacco daily, were more likely to report ever use of cannabis and used cannabis more frequently, and exhibited more externalizing symptoms. These variables did not confound the relation between familial risk for SUDs and a blunted HR recovery.

CONCLUSION

Our findings suggest dysregulated autonomic nervous system (ANS) responding in CPSUDs and contribute to the accumulating evidence for ANS dysregulation as a potential endophenotype for SUDs.

Parenting under the influence: the effects of opioids, alcohol and cocaine on mother-child interaction

Nearly 20% of adults receiving treatment for a substance use disorder live with their minor children (Stanger et al., 1999) and women in drug use treatment are twice as likely as men to have children in their household (Wechsberg et al., 1998). Parental drug use impacts the family through reduced family resources such as money and food, and researchers consistently note parenting deficits among substance users (Solis, Shadur, Burns, & Hussong, 2012). Little is known about differences in parenting and mother-child interaction among mothers with different drugs of choice or among mothers of older children, between 8 and 16 years. This study reports the findings from a sample of treatment seeking opioid, alcohol and cocaine using mothers and their 8-16-year-old child. Findings from a mother-child observational task and self-reported parenting measure indicated less undermining autonomy and higher mother maternal acceptance among opioid compared to alcohol addicted mothers. African American mothers were observed to have fewer negative interactional behaviors than Whites and both African American mothers and children self-reported higher firm control and maternal acceptance. Overall, mothers appeared to struggle with effective discipline with older versus younger children. Findings offer useful information to clinicians seeking to effectively tailor their interventions to women and children who present with different drugs of abuse, race/culture and developmental stage of child.

Child and family factors associated with teacher-reported behavior problems in young children of substance abusers

BACKGROUND

We examined child and family factors associated with teacher-reported behavior problems in 79 children of substance abusers (COSAs).

METHOD

Using regression models, we examined the impact of four family risk factors, cumulatively and individually, on children's behavior and explored children's engagement of adults as a protective factor.

RESULTS

More than half (55%) of children had clinically elevated behavior problems. Cumulative family risks were associated with increased problems, whereas the presence of a father in the home and the child's ability to engage adults were protective.

CONCLUSIONS

These findings may help explain the variation in behavioral outcomes of COSAs.

Parenting and problem behaviors in children of substance abusing parents

BACKGROUND

This study examined parenting practices, parental stress, and problem behaviors among urban Children of Substance Abusing Parents.

METHOD

One hundred and seven children completed the Child Rating Scale and the Children's Depression Inventory. Parents completed the Parenting Practices Scale-Parent Version, Parenting Stress Index, and internalizing and externalizing scales on the Parent Observation of Classroom Adaptation.

RESULTS

Structural Equation Modeling findings support an indirect effects pathway in which unfavorable parenting practices predict parental stress and parental stress predicts internalizing and externalizing behaviors.

CONCLUSION

The results argue for assessing parental stress and including activities to improve the parent-child bond in family intervention programs.

Comparing Psychiatric Symptoms among Children of Substance-Abusing Parents With Different Treatment Histories

It appears that no studies to date have compared the psychiatric functioning of children of substance-abusing parents (COSs) across substance abuse treatment histories (e.g., inpatient, outpatient, residential). Different treatment histories may reflect differences in the severity of drug use, degree of impairment, or drug of choice, which may result in different symptomatology among COSs. Moreover, this information may be important for family-based treatment and prevention planning. In the current study, we examine psychiatric symptoms experienced by children whose parents have different addiction treatment histories. Eighty-one parents in treatment for a substance use disorder who had a 2-8 year old child completed an anonymous, computerized assessment. Respondents reported on their child's symptomatology as well as their own treatment history and current substance use. Overall, children were remarkably similar in psychiatric functioning and demographic characteristics across parent's treatment histories. However, children whose parents had only received medication management or detoxification had significantly higher somatization scores, more social withdrawal, and greater attention problems than children whose parents received outpatient treatment (but not inpatient/residential treatment). Children whose parents had been treated in an inpatient or residential setting had marginally higher attention problems than children whose parents received outpatient treatment (but not inpatient/residential treatment). Differences across treatment histories were reflected in the severity of psychiatric symptomatology in the young children of parents in treatment. However, given the modest size of these differences, prevention and intervention programs with children of substance-abusing parents may not need to be tailored as a function of parental treatment history as recruitment from various treatment centers may provide a sample with similar characteristics and risk profiles.

Perceived child behavior problems, parenting stress, and maternal depressive symptoms among prenatal methamphetamine users

The present study was designed to examine parenting stress, maternal depressive symptoms, and perceived child behavior problems among mothers who used methamphetamine (MA) during pregnancy. Participants were a subsample (n = 212; 75 exposed, 137 comparison) of biological mothers who had continuous custody of their child from birth to 36 months. The subsample was drawn from a larger, ongoing longitudinal study on the effects of prenatal methamphetamine exposure (n = 412; 204 exposed, 208 comparison) (Arria et al in Matern Child Health J 10:293-302 2006). Mothers who used MA during pregnancy reported more parenting stress and more depressive symptoms than a matched comparison group. There were no differences between groups on perceived child behavior problems. In a hierarchical linear model, depressive symptoms, and perceived child behavior problems, but not MA exposure, were statistically significant predictors of parenting stress. Screening for potential parenting problems among mothers with a history of substance abuse is warranted. Parenting interventions targeting depressive symptoms, parenting stress, and child behavior problems are needed for this population.

Estimated effect of prenatal cocaine exposure on examiner-rated behavior at age 7 years

Prenatal cocaine exposure has been linked to increased child behavior difficulties in some studies but not others.

OBJECTIVE

The primary aim was to estimate the relationship between in utero cocaine exposure and child behavioral functioning at age 7 years with ratings made by blinded examiners during a structured testing session. A second aim was to examine whether caregiver drug use and psychological problems might mediate suspected relationships between prenatal cocaine exposure and aspects of examiner-rated behavior.

METHODS

407 children (212 cocaine-exposed, 195 non-exposed) participating in the longitudinal Miami Prenatal Cocaine Study (MPCS) were rated with regard to their behavior during a neuropsychological assessment conducted at age 7 years. Raters were trained research psychometricians blinded to drug exposure status. Individual behavioral items were summarized and the cocaine-behavior relationship was estimated within the context of latent variable modeling, using Mplus software.

RESULTS

Two latent variables, Behavioral Regulation and Sociability, were derived via exploratory latent structure analysis with promax rotation. Prenatal cocaine exposure, statistically controlling for child sex, test age, and prenatal exposure to alcohol, tobacco, and marijuana, was associated with Behavioral Regulation (estimated slope ß=-0.25; 95% CI=-0.48, -0.02; p=0.04) but not Sociability (estimated slope ß=-0.03; 95% CI=-0.26, 0.20; p=0.79). Neither postnatal drug use by caregivers nor the severity of their psychological problems at age 5 follow-up predicted levels of child Behavioral Regulation or Sociability at age 7 years (p>0.10).

CONCLUSIONS

Examiner ratings of child behavior at age 7 revealed less optimal behavioral regulation for prenatally cocaine-exposed compared to non-exposed children, in contrast with what had been previously found from parent-report data. This evidence highlights the potential value of trained observers in assessing behavioral outcomes of children exposed in utero to drugs and other toxicants.

Prenatal Cocaine Disrupts Serotonin Signaling-Dependent Behaviors: Implications for Sex Differences, Early Stress and Prenatal SSRI Exposure

Prenatal cocaine (PC) exposure negatively impacts the developing nervous system, including numerous changes in serotonergic signaling. Cocaine, a competitive antagonist of the serotonin transporter, similar to selective serotonin reuptake inhibitors (SSRIs), also blocks dopamine and norepinephrine transporters, leaving the direct mechanism through which cocaine disrupts the developing serotonin system unclear. In order to understand the role of the serotonin transporter in cocaine's effect on the serotonergic system, we compare reports concerning PC and prenatal antidepressant exposure and conclude that PC exposure affects many facets of serotonergic signaling (serotonin levels, receptors, transporters) and that these effects differ significantly from what is observed following prenatal SSRI exposure. Alterations in serotonergic signaling are dependent on timing of exposure, test regimens, and sex. Following PC exposure, behavioral disturbances are observed in attention, emotional behavior and stress response, aggression, social behavior, communication, and like changes in serotonergic signaling, these effects depend on sex, age and developmental exposure. Vulnerability to the effects of PC exposure can be mediated by several factors, including allelic variance in serotonergic signaling genes, being male (although fewer studies have investigated female offspring), and experiencing the adverse early environments that are commonly coincident with maternal drug use. Early environmental stress results in disruptions in serotonergic signaling analogous to those observed with PC exposure and these may interact to produce greater behavioral effects observed in children of drug-abusing mothers. We conclude that based on past evidence, future studies should put a greater emphasis on including females and monitoring environmental factors when studying the impact of PC exposure.

A randomized pilot study of the Engaging Moms Program for family drug court

In response to the need for effective drug court interventions, the effectiveness of the Engaging Moms Program (EMP) versus Intensive Case Management Services (ICMS) on multiple outcomes for mothers enrolled in family drug court was investigated. In this intent-to-treat study, mothers (N = 62) were randomly assigned to either usual drug court care or the Engaging Moms drug court program. Mothers were assessed at intake and 3, 6, 12, and 18 months following intake. Results indicated that at 18 months post drug court enrollment, 77% of mothers assigned to EMP versus 55% of mothers assigned to ICMS had positive child welfare dispositions. There were statistically significant time effects for both intervention groups on multiple outcomes including substance use, mental health, parenting practices, and family functioning. EMP showed equal or better improvement than ICMS on all outcomes. The results suggest that EMP in family drug court is a viable and promising intervention approach to reduce maternal addiction and child maltreatment.

Parent psychopathology and youth internalizing symptoms in an urban community: a latent growth model analysis

The present study examined the developmental trajectories of youth depression and anxiety symptoms from 6th through 12th grade in a low-income, urban sample (N = 141; mean age = 11.75 years; 88.7% African American). The study also tested the independent contribution of parent mood disorders, anxiety disorders, and substance use disorders assessed in early childhood to initial levels and rate of change in depression and anxiety symptoms from 6th through 12th grade. Possible gender differences in symptom course and strength of parent psychopathology predictors were examined using multiple-group analysis. Results indicated that depression symptoms declined over time for males, whereas depression symptoms initially declined, but then increased for females. In contrast, male and female adolescents each showed a decline in anxiety symptoms throughout adolescence. Findings also indicated that parent mood disorders were the only predictor of youth depression and anxiety symptoms for male and female adolescents in 6th grade. Parent anxiety disorders uniquely predicted the rate of change in depression symptoms among male adolescents. These results underscore the importance of targeting parents with mood and anxiety disorders in urban families in order to reduce the risk for internalizing difficulties in their adolescent youth.

The Case for Examining and Treating the Combined Effects of Parental Drug Use and Interparental Violence on Children in their Homes

This review examines what have been, to this point, generally two divergent lines of research: (a) effects of parental drug abuse on children, and (b) effects of children's exposure to interparental violence. A small, but growing body of literature has documented the robust relationship between drug use and intimate partner violence. Despite awareness of the interrelationship, little attention has been paid to the combined effect of these deleterious parent behaviors on children in these homes. Thus, we argue for the need to examine the developmental impact of these behaviors (both individually and combined) on children in these homes and for treatment development to reflect how each of these parent behaviors may affect children of substance abusers.

Protecting against intergenerational problem behavior: mediational effects of prevented marijuana use on second-generation parent-child relationships and child impulsivity

BACKGROUND

The aims of the study were to identify pathways from parent marijuana use to child problem behavior and parent-child relationships, and to evaluate whether effects of an earlier prevention program delivered to parents when they themselves were early adolescents would have a protective effect on these relationships one generation later.

METHODS

Structural equation models were applied to the data of a second-generation study of a drug abuse prevention trial. Models assessed whether there were sustained marijuana prevention effects on adults who had at least one school-age child at the end of the emerging adulthood period (age 26, n=257), and whether these effects mediated subsequent parent-child relationships and child impulsivity when parents were between the ages of 28 and 34.

RESULTS

Participants originally assigned to the program group used significantly less marijuana in early adulthood than did controls. In turn, parental marijuana use was positively related to child impulsivity and negatively to parental warmth, but not significantly related to parental aggression.

CONCLUSIONS

Results suggest both a direct relationship from parental marijuana use to child impulsivity, as well as indirect relationships through parent-child interactions. Results also strongly support a role for early adolescent prevention programs for drug use, both for participants' own long-term benefit, as well as for the benefit of their future children.

Alcohol and illicit drug dependence among parents: associations with offspring externalizing disorders

BACKGROUND

Previous research indicates that alcohol and drug dependence constitute aspects of a general vulnerability to externalizing disorders that accounts for much of the parent-offspring resemblance for these and related disorders. This study examined how adolescent offspring risk for externalizing psychopathology varies with respect to parental alcoholism and illicit drug dependence.

METHOD

Data from the Minnesota Twin Family Study, a community-based investigation of adolescents (age 17 years, n=1252) and their parents, were used. Lifetime diagnoses of alcohol and drug dependence (among both parents and offspring) and offspring attention deficit hyperactivity disorder, oppositional defiant disorder, conduct disorder, adult antisocial behavior, and nicotine dependence were assessed via structured interviews.

RESULTS

Parental alcohol dependence and parental drug dependence were similarly associated with increased risk for nearly all offspring disorders, with offspring of alcohol and drug-dependent parents having approximately 2-3 times the odds for developing a disorder by late adolescence compared to low-risk offspring. Compared to parental dependence on other illicit drugs, parental cannabis dependence was associated with weaker increased risk for offspring externalizing disorders.

CONCLUSIONS

Both parental alcohol and drug dependence are independently associated with an increased risk for a broad range of externalizing psychopathology among late-adolescent offspring.

Social anxiety disorder: a review of environmental risk factors

Social anxiety disorder (SAD) is a debilitating and chronic illness characterized by persistent fear of one or more social or performance situations, with a relatively high lifetime prevalence of 7% to 13% in the general population. Although the last two decades have witnessed enormous growth in the study of biological and dispositional factors underlying SAD, comparatively little attention has been directed towards environmental factors in SAD, even though there has been much ongoing work in the area. In this paper, we provide a recent review and critique of proposed environmental risk factors for SAD, focusing on traditional as well as some understudied and overlooked environmental risk factors: parenting and family environment, adverse life events, cultural and societal factors, and gender roles. We also discuss the need for research design improvements and considerations for future directions.

Treating paternal drug abuse using Learning Sobriety Together: effects on adolescents versus children

The focus of this study was whether couples-based treatment for substance abuse had comparable secondary benefits on the internalizing and externalizing behaviors of adolescent versus child siblings living in their homes. Couples took part in a couples-based treatment for substance abuse that combines Behavioral Couples Therapy and individual counseling (i.e., Learning Sobriety Together). During a 17-month assessment period, the relationship between parents' functioning (i.e., fathers' drug use as determined by percent days abstinent and parents' dyadic adjustment) as rated by mothers, fathers, and children's teachers and internalizing behavior (as rated by mothers' only) was stronger for children than their adolescent siblings, particularly in terms of children's externalizing behaviors. Interventions that reduce paternal drug use and improve couple functioning may reduce internalizing and externalizing symptoms for children in their homes; however, adolescents may need more intensive interventions to address internalizing and externalizing symptoms.

When ADHD and substance use disorders intersect: relationship and treatment implications

There has been increasing interest in the overlap between attention-deficit/hyperactivity disorder (ADHD) and substance use disorders (SUDs). In this report, we describe the developmental relationship between ADHD and SUDs. ADHD alone and in combination with co-occurring psychopathology is a risk factor for the development of SUDs in adulthood. Conversely, approximately one fifth of adults with SUDs have ADHD. Pharmacotherapeutic treatment of ADHD in children reduces the risk for later cigarette smoking and SUDs in adulthood. In contrast, medication treatment alone of adults with ADHD and current SUD is inadequate for both ADHD and SUD. Stimulant diversion continues to be of concern, particularly in older adolescents and young adults.

Risk factors for the development of emotional and behavioural problems in children born to drug-dependent mothers

BACKGROUND

The study of biological and psychosocial risk factors for the development of emotional and behavioural problems in children of drug-dependent mothers.

METHODS

In a sample of 52 children and drug-dependent mothers participating in a residential intervention programme emotional and behavioural problems were studied in the children by use of the Child Behaviour Checklist (CBCL). The Symptom-Checklist Revised (SCL-90-R) served to assess mental problems in the mother. Drug exposure during pregnancy, various psychosocial risk factors due to the drug-career, and educational status of the mother were assessed by maternal interview. A brief assessment of intelligence of the mother was included.

RESULTS

Among the various biological and psychosocial risk factors, maternal mental health problems, maternal educational status, and a small number of close social relationships correlated significantly with child outcome variables. Multiple regression analyses identified maternal mental health factors as the main predictors of child behaviour.

CONCLUSIONS

Assisting drug-dependent mothers in overcoming the psychosocial sequelae of drug abuse implies also assistance to the children in terms of prevention of emotional and behavioural problems.

Parent psychopathology, parenting, and child internalizing problems in substance-abusing families

A structural model accounting for child internalizing problems in substance-abusing families was tested. Parents receiving substance abuse treatment (N = 242) completed forms about children between the ages of 6 and 18 who resided in their home. The effects of parent gender, child gender, and child age were controlled. Negative parenting was examined as a mediator between parent internalizing and externalizing problems and child anxiety and affective problems using path analysis. Negative parenting mediated relations only between parent internalizing problems and child affective problems. High-positive involvement moderated relations between parent externalizing problems and child internalizing problems. Relations between parent externalizing problems and child anxiety and affective problems were significant only among families in which high-positive involvement was present.

Through a mother's eyes: Sources of bias when mothers with co-occurring disorders assess their children

Mothers are the principal informants on children's emotional and behavioral functioning. Maternal assessments of child functioning can be influenced by a mother's own psychological state. The magnitude and valence of distortion in maternal assessments associated with current maternal mental health and substance abuse symptoms were explored in a clinical sample of 253 mothers with co-occurring disorders and histories of trauma. Analyses estimated the correlation between current maternal symptoms and child assessments after controlling for maternal history of disorders, child's history of service utilization for emotional and behavioral problems, and demographic characteristics. Current maternal psychological distress was associated with more pessimistic assessments on the problem-focused Child Behavior Checklist, whereas current maternal substance abuse problems were associated with more optimistic assessments on both problem-focused and strength-based measures. Clinicians and researchers may choose to take distortion into account when treatment plans or measures of change are based on maternal assessments.

Cigarette smoking in the adolescent children of drug-abusing fathers

OBJECTIVE

This study examined the longitudinal predictors of cigarette smoking in a sample of at-risk adolescents whose fathers were drug abusers (N = 296).

METHODS

At time 1, structured interviews were administered, separately and in private, to male and female youth (X age = 16.3) and their fathers; adolescents were reinterviewed approximately 1 year later (at time 2). Structural equation modeling was used to examine the interrelationship of time 1 paternal tobacco and illicit drug use, father-child relations, adolescent psychological adjustment, and peer group factors and adolescent smoking at time 2. A supplementary analysis assessed the same model with control on the adolescent's age, gender, frequency of contact with the father, and the father's treatment status.

RESULTS

The structural equation model showed a mediational pathway linking paternal tobacco and drug use to a weak and conflictual father-child relationship, which was associated with greater adolescent maladjustment, which in turn was related to deviant peer affiliations, which predicted adolescent smoking at time 2. There was also a direct path from paternal tobacco and drug use to adolescent time 2 smoking. The supplementary analysis found no significant differences between the models with and without control.

CONCLUSIONS

Findings provide evidence of the mechanisms that underlie the association between paternal drug use characteristics and smoking in the adolescent child. Clinical implications suggest the importance of the father-child relationship to smoking prevention programs for at-risk youth.

A comparison of the psychosocial functioning of children with drug-versus alcohol-dependent fathers

The present study compared the psychosocial functioning of children whose fathers primarily abused illicit drugs other than alcohol (n = 51 ) to children from a demographically matched sample of families whose fathers abused alcohol (n = 51). Children with drug-abusing (DA) fathers exhibited significantly more negative child behaviors on a standardized child-rating scale than did children from homes with alcohol-abusing fathers. In addition, a significantly greater proportion of children with DA fathers met clinical cutoffs indicative of psychosocial impairment (n = 23: 45%) than did children whose fathers abused alcohol (n = 5; 10%). Mediation analyses indicated that severity of drug, legal, medical, employment, and family problems partially mediated the relationship between type of family (i.e., families with fathers who had an alcohol problem versus families with fathers who had a drug problem) and children's psychosocial adjustment.

Parenting and Children's Externalizing Problems in Substance-Abusing Families

This study tested associations in path models among positive and negative parenting and children's rule-breaking behavior, aggressive and oppositional behavior, and attention problems for families with a drug-dependent parent. A structural model tested relations between parenting and children's externalizing problems for 251 families with 399 children between the ages of 6 and 18, controlling for nonindependence of ratings at the family level. The model also tested potential moderators, including child age, gender, and ethnicity (White vs. other), and caregiver gender (families with a female substance-abusing caregiver vs. families with a male substance-abusing caregiver). Results indicated that caregiver ratings of monitoring predicted rule-breaking behavior and use of inconsistent discipline predicted ratings of all 3 externalizing syndromes, after controlling parenting and externalizing problems for the effects of the moderators and after controlling significant relations among types of parenting and types of externalizing problems.

Emotional and behavioral problems of children living with drug-abusing fathers: comparisons with children living with alcohol-abusing and non-substance-abusing fathers

Although the effects of paternal alcoholism on the psychosocial adjustment of children are well documented, the impact of fathers' illicit drug abuse on their children is poorly understood. The purpose of this study was to compare the adjustment of children living in families with drug-abusing fathers (n = 40) with that of children with fathers who abused alcohol (n = 40) and children with non-substance-abusing fathers (n = 40). Children with drug-abusing fathers experienced more internalizing and externalizing symptoms than children with alcoholic or non-substance-abusing fathers. Interparental conflict and parenting behavior mediated the relationship between family type and children's adjustment. Interventions to improve fathers' parenting behavior and reduce partner conflict may lead to better adjustment among custodial children of drug-abusing fathers.

Attention-deficit/hyperactivity disorder and the substance use disorders: the nature of the relationship, subtypes at risk, and treatment issues

There is a strong literature supporting a relationship between ADHD and SUD. Clearly, ADHD adolescents with conduct or bipolar disorder as partof their clinical picture are at the highest risk for SUD. ADHD without comorbidity appears to confer an intermediate risk factor for SUD that appears to manifest in young adults and college students. Both family genetic and self-medication influences may be operational in the development and continuation of SUD in ADHD subjects: however, systematic data are lacking. Patients with ADHD and SUD require multi-modal intervention incorporating addiction and mental health treatment. Pharmacotherapy in individuals with ADHD and SUD needs to take into consideration abuse liability, potential drug interactions, and compliance concerns. Although the existing literature has provided important information on the relationship of ADHD and SUD, it also points to a number of areas in need of further study. The mechanism by which untreated ADHD leads toSUD and the risk reduction of ADHD treatment on later SUD, needs to be understood better. The influence of adequateness of treatment of ADHD on later SUD needs to be delineated. Given the prevalence and major morbidity and impairment caused by SUD and ADHD. prevention and treatment strategies for these patients need to be developed and evaluated further.

The impact of parental problem drug use on children: what is the problem and what can be done to help?

AIM

To review the literature on the impact of parental problem drug use on children, and indicate the efficacy of key evaluated interventions to reduce the impact of parental drug use on children.

METHODS

Comprehensive narrative review of English language published research and intervention spanning the last three decades identified through searching library databases and citation.

FINDINGS

Problem drug use can impede parenting and the provision of a nurturing environment. Although small-scale, localized and resource-intensive these key evaluated interventions show cautious optimism that problem drug-using parents can reduce drug use and achieve better family management. Children have rarely been directly the focus of intervention.

CONCLUSIONS

Wider application and more rigorous evaluation of interventions in this area are needed. Given the scale of the problem it is important to establish how statutory services can apply the lessons of these more localized interventions.

Effects of gender and level of parental involvement among parents in drug treatment

Most studies of parents in drug treatment have focused exclusively on mothers, and few studies have examined the effects of parents' level of involvement with their children on the parents' drug use and psychological functioning, either before or after treatment. This study examined mothers and fathers (n = 331) who were parents of children under the age of 18; participants were sampled from 19 drug treatment programs across four types of treatment modalities in Los Angeles County. A majority of each group (57% of 214 mothers and 51% of 117 fathers) were classified as being highly involved with their children. At the baseline assessment, higher parental involvement was related to lower levels of addiction severity, psychological severity, and symptoms of psychological distress, and to higher levels of self-esteem and perception of parenting skills. In general, fathers had higher levels of alcohol and drug-use severity than did mothers, but fathers who were more involved with their children showed lower levels of addiction severity than fathers who were less involved. Parental involvement at baseline was unrelated to drug use at the 12-month follow-up, although parents who were less involved with their children reported experiencing more stressors. Given the association of parental involvement with lower levels of addiction severity and psychological distress at baseline, treatment protocols should build upon the positive relationships of parents with their children, and seek to improve those of less-involved parents.

Parent figure transitions and delinquency and drug use among early adolescent children of substance abusers

Children of substance abusing parents have an elevated risk for experiencing disruptions in household composition and for engaging in problem behaviors. This study investigated whether multiple parent figure transitions predicted the likelihood of delinquency and drug use among a sample of early adolescents with parents receiving methadone treatment for opiate addiction. Controlling for baseline delinquency, child characteristics, family conflict, parental depression, and parent criminal history, a greater number of parenting disruptions during the longitudinal study period was associated with a higher probability of delinquent behavior. Gender moderated the effect of parent figure transitions in a parallel analysis for drug use. After accounting for baseline drug use and potentially confounding factors, only adolescent females had a higher likelihood of drug use as the number of family disruptions increased. In contrast, age was strongly associated with drug use for males. A subgroup of youths who experienced tremendous family instability and had no single consistent parent figure during the study period were at extreme risk for delinquent behavior. The findings are interpreted in terms of cumulative stress resulting from multiple parenting disruptions over time and differential influences on the expression of problem behaviors depending on gender.

Oppositional defiant disorder and conduct disorder: a review of the past 10 years, part II

OBJECTIVE

To review empirical findings on oppositional defiant disorder (ODD) and conduct disorder (CD).

METHOD

Selected summaries of the literature over the past decade are presented.

RESULTS

Research on ODD and CD during the past decade has addressed the complexity involved in identifying the primary risk factors and developmental pathways to disruptive behavior disorders (DBD). In some domains, research is entering an entirely new phase because of the availability of new technologies. In others, larger data sets and more complicated methodological and statistical techniques are testing increasingly complex models. Yet questions remain regarding the most useful subtyping systems, the identification of the most significant risk factors, and the relationships between risk factors from multiple domains.

CONCLUSIONS

Convincing evidence of causal linkages remains elusive. Research has questioned the notion that CD is intractable, especially when multiple domains of risk and impairment are the targets of intervention. It is apparent that there is not one single causative factor; thus it is not likely that one single modality will suffice to treat CD. Future steps will involve the restructuring of diagnostic criteria to capture adequate subtypes and indicators, clarification of the neurological underpinnings of the disorder, and refinement in the models available to explain the varied pathways to DBD.

Coping with the stress of parental depression: parents' reports of children's coping, emotional, and behavioral problems

Examined children's coping and involuntary responses to the stress of living with a depressed parent in relation to their symptoms of anxiety/depression and aggression. Sixty-six clinically depressed adults rated their children's (ages 7 to 17 years old; N = 101) coping and involuntary responses to parental stressors and anxiety/depressive and aggressive behavior symptoms. Based on parent report, children of depressed parents had high rates of symptoms of anxiety/depression and aggression, were exposed to moderate levels of parental stressors (parental intrusiveness, parental withdrawal), and responded to the stress of living with a depressed parent in ways that were associated with symptoms of psychopathology. Children's use of secondary control coping (e.g., positive thinking, acceptance, distraction) was associated with fewer anxiety/depression and aggression symptoms. In contrast, involuntary engagement responses (e.g., rumination, intrusive thoughts) were associated with more anxiety/depression and aggression symptoms. Path analyses revealed that a model in which secondary control coping and involuntary engagement stress responses mediated the relation between family stressors and child symptoms provided the best fit with the data. Implications of these findings for developing interventions for children to reduce the risk of psychopathology are discussed.

Behavioral outcome of preschoolers exposed prenatally to cocaine: role of maternal behavioral health

OBJECTIVE

To examine the impact of prenatal cocaine exposure and maternal behavioral health (recent drug use and psychological functioning) on child behavior at age 5 years.

METHOD

In this longitudinal investigation, maternal report of child behavior was assessed using the Achenbach Child Behavior Checklist (CBCL) in 140 cocaine-exposed and 181 noncocaine-exposed (61 alcohol, tobacco, and/or marijuana-exposed, and 120 nondrug-exposed) low-income, African American children. Structural equation modeling was used to estimate suspected causal relationships between indicators of maternal behavioral health at 5-year follow-up, according to self-report on a modified Addiction Severity Index (ASI) and CBCL scores.

RESULTS

Prenatal cocaine exposure was not related to child behavior at age 5. Recent maternal drug use and psychological functioning had relationships with CBCL Internalizing and Externalizing scores. However, when considered within a combined model, only maternal psychological functioning remained significant.

CONCLUSIONS

Findings highlight the importance of maternal functioning in the behavioral outcome of children exposed prenatally to cocaine.

Predictors of internalizing and externalizing problems among children of cocaine and opiate dependent parents

We tested associations in structural models among parent individual problems (severity of drug problems, medical problems, psychiatric symptoms), family problems, and children's internalizing and externalizing problems. Results were compared for cocaine versus opiate dependent parents, mothers versus fathers, boys versus girls, and older versus younger children. Cocaine and opiate dependent parents in treatment (N=211) were interviewed about their substance use, psychiatric symptoms, and interpersonal problems and completed a measure of family problems. Parents also rated children's internalizing and externalizing problems. In structural models controlling for the significant correlations between parent and family problems and between children's internalizing and externalizing problems, family problems but not individual parent problems predicted children's internalizing and externalizing symptoms. Models were similar across all groups compared with the exception of parent gender, with significant relations between parent and family problems for mothers but not for fathers. In addition, older girls were more deviant relative to their same-age and gender peers than the younger girls and boys. These results suggest that the personal problems of drug dependent mothers may influence children's problems indirectly by increasing family problems. For drug dependent fathers, family problems were an independent predictor of children's problems.

Syndromal versus contextualized personality assessment: differentiating environmental and dispositional determinants of boys' aggression

Two studies examined how "syndromal" approaches to assessment confound differences between individuals in the person and situation variables that contribute to their behavior. In a field study, a widely used instrument was found to be sensitive to the base rates of boys' aggression but, as expected, did not discriminate between boys who were similar in their behavior base rates but different in their social environments and how they responded to them. A laboratory experiment replicated this finding and demonstrated that social observers discriminated between targets on the basis of their functional properties even though syndrome scores did not. The results clarify how syndromal methods can obscure situational factors, conflict with people's social knowledge, and reinforce the view that syndromes exist "in the individual" rather than in person-environment interactions. Implications for developing more contextually sensitive instruments are discussed.

The impact of maternal alcohol and illicit drug use on children's behavior problems: evidence from the children of the national longitudinal survey of youth

This study uses Children of the National Longitudinal Survey of Youth to test for evidence of a causal relationship between maternal alcohol, marijuana, and cocaine use, and children's behavior problems. Ordinary least squares (OLS) results provide strong evidence that substance use is associated with behavior problems. However, OLS estimation fails to account for unobserved factors that may be correlated with substance use and child behavior. To account for this problem, mother-child and family fixed-effects models are tested. The results suggest that maternal illicit drug use is positively associated with children's behavior problems, while alcohol use has a less consistent impact.
