Parent alcoholism impacts the severity and timing of children's externalizing symptoms

Genotype-environment interplay in associations between maternal drinking and offspring emotional and behavioral problems

BACKGROUND

While maternal at-risk drinking is associated with children's emotional and behavioral problems, there is a paucity of research that properly accounts for genetic confounding and gene-environment interplay. Therefore, it remains uncertain what mechanisms underlie these associations. We assess the moderation of associations between maternal at-risk drinking and childhood emotional and behavioral problems by common genetic variants linked to environmental sensitivity (genotype-by-environment [G × E] interaction) while accounting for shared genetic risk between mothers and offspring (GE correlation).

METHODS

We use data from 109 727 children born to 90 873 mothers enrolled in the Norwegian Mother, Father, and Child Cohort Study. Women self-reported alcohol consumption and reported emotional and behavioral problems when children were 1.5/3/5 years old. We included child polygenic scores (PGSs) for traits linked to environmental sensitivity as moderators.

RESULTS

Associations between maternal drinking and child emotional (β1 = 0.04 [95% confidence interval (CI) 0.03-0.05]) and behavioral (β1 = 0.07 [0.06-0.08]) outcomes attenuated after controlling for measured confounders and were almost zero when we accounted for unmeasured confounding (emotional: β1 = 0.01 [0.00-0.02]; behavioral: β1 = 0.01 [0.00-0.02]). We observed no moderation of these adjusted exposure effects by any of the PGS.

CONCLUSIONS

The lack of strong evidence for G × E interaction may indicate that the mechanism is not implicated in this kind of intergenerational association. It may also reflect insufficient power or the relatively benign nature of the exposure in this sample.

Association between caregiver and household alcohol use and child behavior problems in KwaZulu Natal, South Africa

We explored the association between household alcohol use and behavior problems among South-African children, using data from the Asenze study, a population-based cohort of South African children and their caregivers. Household alcohol use and child behavior were assessed when children were 6-8 years old. To examine the association, we performed linear regressions. The sample included 1383 children with complete data under the care of 1251 adults. Children living in a household where self-reported caregiver alcohol use was scored as hazardous (4.6%) had higher levels of problem behavior (β = 1.94, 95% CI 0.06-3.82). There were no statistically significant associations between reported hazardous alcohol use by another member of the household (14.5%) and child problem behavior. Hazardous household alcohol use was associated with child problem behavior and this effect appeared to be mainly driven by primary caregiver use.

The Secondary Harms of Parental Substance Use on Children's Educational Outcomes: A Review

Parental substance use, that is alcohol and illicit drugs, can have a deleterious impact on child health and wellbeing. An area that can be affected by parental substance use is the educational outcomes of children. Current reviews of the literature in the field of parental substance use and children's educational outcomes have only identified a small number of studies, and most focus on children's educational attainment. To grasp the available literature, the method from Arksey and O'Malley (2005) was used to identify literature. Studies were included if they were empirical, after 1950, and focused on children's school or educational outcomes. From this, 51 empirical studies were identified which examined the relationship between parental alcohol and illicit drug use on children's educational outcomes. Five main themes emerged which included attainment, behavior and adjustment, attendance, school enjoyment and satisfaction, academic self-concept, along with other miscellaneous outcomes. This paper highlights the main findings of the studies, the gaps in the current literature, and the challenges presented. Recommendations are made for further research and interventions in the areas of parental substance use and child educational outcomes specifically, but also for broader areas of adversity and child wellbeing.

A Systematic Review of Household and Family Alcohol Use and Childhood Neurodevelopmental Outcomes in Low- and Middle-Income Countries

Childhood exposure to alcohol misuse by household adults has been related to childhood developmental delay, cognitive impacts, mental illness, and problem behaviours. Most evidence comes from high income countries. This systematic review only included studies from low- and middle-income countries (LMICs). Five databases were searched from 1990-2020. Twenty-eight studies of children 0-12 years were included, with 42,599 participants from 11 LMICs. The most common outcome was behavioural problems/disorders (19 studies). Despite varying study designs, this review found that alcohol misuse by household members in LMICs is associated with adverse child neurodevelopmental outcomes, although casual inferences cannot be drawn in the absence of well conducted prospective studies. Statistically significant correlations were described between parental alcohol misuse and child emotional and behavioural difficulties, cognitive delay, and risky behaviours. In future, prospective cohort studies are recommended, with adjustment for confounders.

The Development of Externalizing and Internalizing Behaviors Among Youth With or Without a Family History of Substance Use Disorder: The Indirect Effects of Early-Life Stress and Impulsivity

Youth with a family history of substance use disorder (FH+) are more prone to have externalizing and internalizing problems compared to youth without a family history of substance use disorder (FH-), increasing the likelihood of later maladjustment. However, mechanisms for this association remain understudied. In this longitudinal study, we examined if FH+ youth are more likely to experience early-life stressors (ELS), which in turn would increase impulsivity and the expression of externalizing and internalizing behaviors. Data were collected from youth and a parent (n = 386) during a baseline assessment (age 10-12 years) and every six months when the youth was 13-16 years old. In support of the primary hypothesis, FH+ youth reported higher levels of externalizing and internalizing behaviors through ELS to impulsivity providing a developmental pathway through which FH+ youth are more prone to externalizing and internalizing problems.

Resilience buffers the effects of sleep problems on the trajectory of suicidal ideation from adolescence through young adulthood

OBJECTIVES

To examine both the between-person and within-person effects of sleep problems on the trajectory of suicidal ideation from ages 14 to 22 and investigate whether resilience moderates the effects. Age and sex differences were explored in the main and interaction effects of sleep problems and resilience on suicidal ideation.

METHODS

The study sample included 2491 adolescents (1260 males and 1231 females) who participated in a prospective study spanning 2009 through 2016 in northern Taiwan. Sex-stratified multilevel models were used to examine the between-person and within-person effects of sleep problems and the moderating effects of resilience on the trajectory of suicidal ideation in males and females.

RESULTS

Across adolescents, higher levels of sleep problems contributed to an elevated risk of suicidal ideation for both sexes. Within individuals, a higher risk of suicidal ideation was observed when an adolescent's sleep problems exceeded their typical levels. The within-person effects of sleep problems were further determined to vary by age in males, with the effects gradually decreasing throughout late adolescence but increasing again in young adulthood. The buffering effects of resilience were only observed in females. The relationships between the within-person effects of sleep problems and suicidal ideation were only significant in female adolescents with low levels of resilience.

CONCLUSIONS

Our findings extend the research by demonstrating both the between-person and within-person association between sleep problems and suicidal ideation. We further revealed age and sex differences in the within-person effects of sleep problems and the buffering effects of resilience. Prevention and intervention programs that target sleep problems could be tailored based on individuals' age, sex, and levels of resilience to prevent suicidal ideation.

Fetal Alcohol Spectrum Disorder resources for educators working within primary school settings: a scoping review protocol

INTRODUCTION

Many children affected by Fetal Alcohol Spectrum Disorder (FASD) exhibit neurocognitive delays that contribute to secondary consequences, including a disrupted school experience. Educators often have limited knowledge or experience in the identification, referral, management and accommodation of students with FASD. Effective resources and tools for educators are crucial to ensure these students are supported in their ongoing learning, development and school participation. This scoping review aims to identify and evaluate resources for educators that aid in the identification, management, or accommodation of students with FASD.

METHODS AND ANALYSIS

A search will be conducted in 9 peer-reviewed and 11 grey literature databases, Google search engine, two app stores and two podcast streaming services (planned search dates: November 2020 to February 2021). Relevant experts, including researchers, health professionals and individuals with lived experience of FASD, will be contacted in February and March 2021 to identify additional (including unpublished) resources. Resources will be selected based on registered, prespecified inclusion-exclusion criteria, and the quality of included resources will be critically appraised using a composite tool based on adaptions of the National Health and Medical Research Council FORM Framework and the iCAHE Guideline Quality Checklist. Relevant experts will also be requested to provide feedback on included resources.

ETHICS AND DISSEMINATION

Ethical approval for this scoping review was obtained from the University of Sydney Human Research Ethics Committee (2020/825). Results of the review will be disseminated through a peer-reviewed publication, conference presentations, and seminars targeting audiences involved in the education sector.

Early Childhood Risk and Protective Factors Predicting Resilience against Adolescent Substance Use

We examined associations between early childhood (first 3 years of life) risk and protective factors and resilience against adolescent substance use in a prospective sample of alcoholic and non-alcoholic families. We defined resilience as low or no substance use in the context of adversity (having a father with alcohol problems). The sample included 227 families recruited from birth records when children were 12 months old and followed longitudinally to 15-17 years of child ages (n = 182). Adolescents were grouped into 4 categories: Non-challenged (non-alcoholic parent, no adolescent substance use, n = 50), Troubled (non-alcoholic parent, adolescent substance use, n = 30), Resilient (alcoholic parent, no adolescent substance use, n = 36), and Vulnerable (alcoholic parent and adolescent substance use, n = 66). Multivariate analyses were used to examine group differences (resilient vs. vulnerable; non-challenged vs. troubled) in child and parent characteristics and family relationships domains. Children in the troubled group compared to non-challenged had lower effortful control and emotion-regulation, and those in the resilient group were more unadaptable or reactive to novelty compared to the vulnerable group. Parents of resilient compared to vulnerable children reported significantly lower alcohol symptoms and more partner aggression. Finally, fathers of resilient compared to vulnerable children were less aggravated with them in early childhood. Results highlight the importance of continuous measures of alcohol problems, early childhood functioning, and family characteristics for associations with adolescent risk and resilience.Passive gene-environment correlations may account for associations between parent alcohol problem severity and adolescent substance use.

Does Stress Mediate the Relation between Caregivers' Victimization and Child Behavioral Outcomes? A Prospective Examination

Children with internalizing and externalizing difficulties are at risk for long-term negative effects in adulthood and are impacted by several caregiver factors. Findings of the present study are consistent with previous studies that found direct associations between caregiver victimization history (e.g., physical and sexual abuse) and child behavior problems. Examination of potential mechanisms revealed that caregiver everyday stress related to relationships/responsibilities (RR) served as a mediator between caregiver victimization history and increased children's internalizing symptoms. Though there may be other pathways that contribute to this relation, there does seem to be clinical and policy utility of this knowledge, particularly for at-risk families that are faced with high levels of everyday RR stress. Attenuation of this impact may be accomplished through connection to community resources such as access to family counseling to mitigate relational stress and policy addressing disparities.

Parental alcohol intoxication and adverse health outcomes among offspring. A 4-year follow up HUNT study among 2399 Norwegian adolescents

This study aimed to investigate whether experience of parental alcohol intoxication was associated with adverse health outcomes among adolescents four years later. A population-based Norwegian cohort study of 2399 adolescents who participated in the Young-HUNT1 Survey 1995-97 (T1, 13-15 years old) was followed up four years later (T2) in 2000 (Young-HUNT2, 17-19 years old). Measures were based on adolescent self-report of exposure to parental alcohol intoxication, self-rated general health, mental distress (SCL-5) and lifetime hospital admission. Multivariable logistic regression analyses, adjusted for gender, age and parental education were applied. Results show that half of the adolescents (51%) had seen parents intoxicated at age 13-15 years. Four years later, those who had reported parental alcohol intoxication at T1 had increased odds of admission to hospital with odds ratios ranging from OR1.3; CI 1.0-1.7 to OR 2.2; CI 1.3-3.9, poorer self-rated health (odds ratio ranging from 1.8;1.2-2.6 to 2.0;1.1-3.7) and more mental distress (odds ratio ranging from 1.7;1.1-2.5 to 1.9;1.0-3.6). Furthermore, the increased frequency of experience of parental alcohol intoxication are associated with higher prevalence of admission to hospital and mental distress and lower levels of self-rated health. Findings from this large, representative population of Norwegian adolescents indicate that adverse health outcomes among adolescents in a general population are related to relatively common heavy drinking behaviours among parents.

Are Parental Alcohol Use Disorder Histories Associated With Offspring Behavior Problems at Age 2?

OBJECTIVE

Studies of clinical and high-risk samples have demonstrated associations between parental alcohol use disorders (AUDs) and offspring's internalizing and externalizing behavior problems during adolescence and early adulthood. It remains unclear, however, whether associations between parental AUD histories and offspring behavior problems are evident among very young offspring who were not directly exposed to a parent who experienced an active AUD episode during the child's lifetime. The present study sought to evaluate internalizing and externalizing behavior problems among young children as a function of paternal and maternal AUD histories and associated clinical features.

METHOD

The community sample consisted of 160 families with a 2-year-old child and parents who did not experience an AUD episode since the child was born. Parental AUD histories and associated clinical features were evaluated with semistructured interviews, and parental reports of child internalizing and externalizing behaviors were assessed with an age-appropriate behavior checklist.

RESULTS

In contrast to previous findings from clinical and high-risk samples, when paternal and maternal AUD histories and associated clinical features were evaluated as predictors of child behavior problems, no statistically significant associations were detected (βs ranged from .01 to .18). Moderating effects of sex of the offspring were also not significant.

CONCLUSIONS

Parental AUD histories do not appear to confer risk for offspring internalizing or externalizing behavior problems at age 2. The emergence of such behavior problems may be limited to specific developmental periods during childhood or reflect the impact of direct exposure to parents with alcohol-related problems.

Extensions of Multiple-Group Item Response Theory Alignment: Application to Psychiatric Phenotypes in an International Genomics Consortium

Large-scale studies spanning diverse project sites, populations, languages, and measurements are increasingly important to relate psychological to biological variables. National and international consortia already are collecting and executing mega-analyses on aggregated data from individuals, with different measures on each person. In this research, we show that Asparouhov and Muthén's alignment method can be adapted to align data from disparate item sets and response formats. We argue that with these adaptations, the alignment method is well suited for combining data across multiple sites even when they use different measurement instruments. The approach is illustrated using data from the Whole Genome Sequencing in Psychiatric Disorders consortium and a real-data-based simulation is used to verify accurate parameter recovery. Factor alignment appears to increase precision of measurement and validity of scores with respect to external criteria. The resulting parameter estimates may further inform development of more effective and efficient methods to assess the same constructs in prospectively designed studies.

The Hedonic Character of Nostalgia: An Integrative Data Analysis

We conducted an integrative data analysis to examine the hedonic character of nostalgia. We combined positive and negative affect measures from 41 experiments manipulating nostalgia ( N = 4,659). Overall, nostalgia inductions increased positive and ambivalent affect, but did not significantly alter negative affect. The magnitude of nostalgia’s effects varied markedly across different experimental inductions of the emotion. The hedonic character of nostalgia, then, depends on how the emotion is elicited and the benchmark (i.e., control condition) to which it is compared. We discuss implications for theory and research on nostalgia and emotions in general.

Disentangling the effects of intergenerational transmission of depression from adolescence to adulthood: the protective role of self-esteem

This study aimed to disentangle time-stable and time-varying effects of maternal and paternal depression on trajectories of adolescent depression from ages 13 to 23 and examined whether self-esteem moderates the examined associations. Sex differences in the direct effects of parental depression and its interacted effects with self-esteem were further explored. Data were collected from a sample of 2502 adolescents and their parents participating in a panel study spanning from the year 2000 to 2009 in northern Taiwan. Multilevel modeling was conducted to disentangle the time-stable and time-varying effects of parental depression on adolescent depression. The moderating role of self-esteem and the potential sex differences in the transmission process were tested by adding two- and three-way interactions among parental depression, self-esteem, and sex of adolescents in the models. As predicted, significant time-stable intergenerational transmission of depression was found, indicating that adolescents of parents with higher levels of depression were at increased risks for depression. Self-esteem was further found to buffer the negative effects of maternal depression on development of depression in offspring. No sex-specific intergenerational transmission of depression was observed. In sum, both maternal and paternal depression contributed to elevated levels of adolescent depression. The effects of maternal depression, however, may not be uniform, but depend on levels of self-esteem. Intervention and prevention strategies that enhance self-esteem may help participants withstand the negative effects of maternal depression.

The Enduring Effects of Parental Alcohol, Tobacco, and Drug Use on Child Well-being: A Multilevel Meta-Analysis

The effects of psychoactive substance abuse are not limited to the user, but extend to the entire family system, with children of substance abusers being particularly at risk. This meta-analysis attempted to quantify the longitudinal relationship between parental alcohol, tobacco, and drug use and child well-being, investigating variation across a range of substance and well-being indices and other potential moderators. We performed a literature search of peer-reviewed, English language, longitudinal observational studies that reported outcomes for children aged 0 to 18 years. In total, 56 studies, yielding 220 dependent effect sizes, met inclusion criteria. A multilevel random-effects model revealed a statistically significant, small detriment to child well-being for parental substance abuse over time (r = .15). Moderator analyses demonstrated that the effect was more pronounced for parental drug use (r = .25), compared with alcohol use (r = .13), tobacco use (r = .13), and alcohol use disorder (r = .14). Results highlight a need for future studies that better capture the effect of parental psychoactive substance abuse on the full breadth of childhood well-being outcomes and to integrate substance abuse into models that specify the precise conditions under which parental behavior determines child well-being.Registration: PROSPERO CRD42017076088.

A Latent Class Analysis of Parental Alcohol and Drug Use: Findings from the Avon Longitudinal Study of Parents and Children

•

We identified four parental substance use classes using quantity-frequency measures.

•

Heavy use of alcohol formed a class which also included a large proportion of drug users.

•

Mothers’ and their partner’s tended to have similar patterns of substance use behaviours.

Previous measures of parental substance use have often paid limited attention to the co-occurrence of alcohol and drugs, or to the between-parent dynamics in the use of substances. These shortcomings may have important implications for our understandings of the relationship between parental substance use and child wellbeing. Using data from the Avon Longitudinal Study of Parents and Children, a UK community-based cohort study from 1990 onwards (n = 9,451), we identified groups of parental substance use using latent class analysis. The 4-class solution offered the best fit, balancing statistical criteria and theoretical judgement. The results show distinct classes across the range of parental substance use, including very low users, low users, moderate users and heavy users. These classes suggest that substance use patterns among mothers are somewhat mirrored by those of their partners, while heavy use of alcohol by mothers and their partners is related to increased mothers drug use. We suggest that studies that investigate the effects of parental substance use on child wellbeing should pay greater attention to the dynamics of substance use by parental figures.

Maternal Drinking and Child Emotional and Behavior Problems

BACKGROUND AND OBJECTIVES

Maternal drinking is associated with child emotional and behavior problems. There is, however, a lack of studies that properly account for confounding. Our objective was to estimate the association between at-risk drinking in mothers of young children and child emotional and behavior problems, taking into account the passive transmission of familial risk.

METHODS

This population-based sample consists of 34 039 children nested within 21 911 nuclear families and 18 158 extended families from the Norwegian Mother, Father, and Child Cohort Study. Participants were recruited between 1999 and 2009 during routine ultrasound examinations. Data were collected during the 17th and 30th gestational week and when the children were 1.5, 3, and 5 years old. We applied a multilevel structural equation model that accounted for unobserved familial risks.

RESULTS

Children of mothers with at-risk drinking had a higher likelihood of behavior problems (β = 3.53; 95% confidence interval [CI] 3.01 to 4.05) than children of mothers with low alcohol consumption. This association was reduced after adjusting for factors in the extended family (β = 1.93; 95% CI 1.16 to 2.71) and the nuclear family (β = 1.20; 95% CI 0.39 to 2.01). Maternal at-risk drinking had a smaller association with child emotional problems (β = 1.80; 95% CI 1.26 to 2.34). This association was reduced after adjusting for factors in the extended family (β = 0.67; 95% CI -0.12 to 1.46) and the nuclear family (β = 0.58; 95% CI -0.31 to 1.48).

CONCLUSIONS

The results suggest an association between maternal at-risk drinking and child behavior problems. A reduction in maternal drinking may improve outcomes for children with such symptoms.

Influence of early adversity on cortisol reactivity, SLC6A4 methylation and externalizing behavior in children of alcoholics

BACKGROUND

Children of parents with alcoholism face considerable stress, and often have externalizing behaviors. Early adversity is known to affect DNA methylation and the functioning of the HPA axis. We investigated the association of early adversity with cortisol reactivity, 5HTTLPR genotype, site specific DNA methylation in the SLC6A4 gene and externalizing behavior in children of alcoholics (COA), and a matched sample of control children.

METHODS

We examined children of alcoholics (N = 50) and age matched control children (N = 50) for exposure to early adversity (both prenatal and postnatal), assessed their salivary cortisol reactivity and evaluated their levels of emotional and behavioral difficulty in terms of externalizing and internalizing behavior. Site-specific DNA methylation at a previously characterized SLC6A4 region was determined in salivary DNA using pyrosequencing. The 5HTTLPR region of the SLC6A4 gene was also genotyped.

RESULTS

COA had significantly higher experience of early adversity than control children. Cortisol reactivity was reduced in COA, and negatively correlated with early adversity. Both early adversity and cortisol reactivity correlated with externalizing behavior. SLC6A4 methylation was higher in COA, and correlated with early adversity. SLC6A4 genotype did not show association with any of the variables.

CONCLUSION

Our study provides further evidence that early adversity is associated with blunted cortisol reactivity, increased site-specific CpG DNA methylation at the SLC6A4 gene, and high externalizing behavior.

Substance abuse in parents and subsequent risk of offspring psychiatric morbidity in late adolescence and early adulthood: A longitudinal analysis of siblings and their parents

The effects of substance abuse on other family members are not fully established. We estimate the contribution of parental substance abuse on offspring psychiatric morbidity in late adolescence and early adulthood, with emphasis on the timing and persistency of exposure. We used a nationally representative 20% sample of Finnish families with children born in 1986-1996 (n = 136,604) followed up in 1986-2011. We identified parental substance abuse and offspring psychiatric morbidity from hospital discharge records, death records and medication registers. The effects of parental substance abuse at ages 0-4, 5-9 and 10-14 on psychiatric morbidity after age 15 were estimated using population averaged and sibling fixed effects models; the latter controlling for unobserved factors shared by siblings. Parental substance abuse at ages 0-14 was associated with almost 2-fold increase in offspring psychiatric morbidity (HR = 1.86, 95% CI 1.78-1.95). Adjustment for childhood parental education, income, social class and family type reduced these effects by about 50%, with some further attenuation after adjustment for time-varying offspring characteristics. In the sibling fixed effects models those exposed at 0-4 or 5-9 years had 20% (HR = 1.20, 95% CI 0.90-1.60) and 33% (HR = 1.33, 95% CI 1.01-1.74) excess morbidity respectively. Also in sibling models those with early exposure at ages 0-4 combined with repeated exposure in later childhood had about 80-90% higher psychiatric morbidity as compared to never exposed siblings (e.g. for those exposed throughout childhood HR = 1.81, 95% CI 1.01-3.25). Childhood exposure to parental substance abuse is strongly associated with subsequent psychiatric morbidity. Although these effects are to a large extent due to other characteristics shared within the parental home, repeated exposure to parental substance abuse is independently associated with later psychiatric morbidity.

Influence of Parental Alcohol Dependence Symptoms and Parenting on Adolescent Risky Drinking and Conduct Problems: A Family Systems Perspective

BACKGROUND

Parental alcohol problems are associated with adverse adolescent outcomes such as risky drinking and conduct problems. Important questions remain about the unique roles of fathers' and mothers' alcohol problems and differences and/or similarities in pathways of risk across ethnicity and gender. In this study, we used a family systems approach to consider spillover and crossover effects of fathers' and mothers' alcohol problems (number of alcohol dependence symptoms [ADS]) and parenting behaviors in relation to adolescents' risky drinking and conduct problems.

METHODS

The sample included 1,282 adolescents (aged 12 to 17) and their parents from the Collaborative Study on the Genetics of Alcoholism. Parents completed the Semi-Structured Assessment for the Genetics of Alcoholism (SSAGA), and adolescents completed an adolescent version of SSAGA. Data were analyzed using multivariate structural equation modeling.

RESULTS

Fathers' ADS count was associated with higher adolescent risky drinking and conduct problems indirectly via disruption to fathers' and mothers' positive parenting behaviors, whereas mothers' ADS count was not associated with adolescents' risky drinking and conduct problems directly or indirectly via positive parenting behaviors. No differences in these associations were found across ethnic background and offspring gender.

CONCLUSIONS

Findings highlight the importance of considering the unique roles of fathers' and mothers' ADS in influencing family processes and adolescent outcomes.

Recovering Predictor-Criterion Relations Using Covariate-Informed Factor Score Estimates

Although it is currently best-practice to directly model latent factors whenever feasible, there remain many situations in which this approach is not tractable. Recent advances in covariate-informed factor score estimation can be used to provide manifest scores that are used in second-stage analysis, but these are currently understudied. Here we extend our prior work on factor score recovery to examine the use of factor score estimates as predictors both in the presence and absence of the same covariates that were used in score estimation. Results show that whereas the relation between the factor score estimates and the criterion are typically well recovered, substantial bias and increased variability is evident in the covariate effects themselves. Importantly, using covariate-informed factor score estimates substantially, and often wholly, mitigates these biases. We conclude with implications for future research and recommendations for the use of factor score estimates in practice.

Advancing the Study of Adolescent Substance Use Through the Use of Integrative Data Analysis

A wealth of information is currently known about the epidemiology, etiology, and evaluation of drug and alcohol use across the life span. Despite this corpus of knowledge, much has yet to be learned. Many factors conspire to slow the pace of future advances in the field of substance use including the need for long-term longitudinal studies of often hard-to-reach subjects who are reporting rare and episodic behaviors. One promising option that might help move the field forward is integrative data analysis (IDA). IDA is a principled set of methodologies and statistical techniques that allow for the fitting of statistical models to data that have been pooled across multiple, independent samples. IDA offers a myriad of potential advantages including increased power, greater coverage of rare behaviors, more rigorous psychometric assessment of theoretical constructs, accelerated developmental time period under study, and enhanced reproducibility. However, IDA is not without limitations and may not be useful in a given application for a variety of reasons. The goal of this article is to describe the advantages and limitations of IDA in the study of individual development over time, particularly as it relates to trajectories of substance use. An empirical example of the measurement of polysubstance use is presented and this article concludes with recommendations for practice.

Associations between observed temperament in preschoolers and parent psychopathology

Parent history of psychopathology is an established marker of children's own risk for later disorder and can therefore be used as a means of validating other risks, such as child temperament. While associations between children's temperament and parent psychopathology have been reported, few studies have used observational measures of child temperament or examined trait interactions, particularly between children's affective and regulatory traits such as effortful control (EC). In this bottom-up family study of 968 three-year-olds and their parents, we examined interactions between preschoolers' observed positive and negative affectivity (NA) and EC as predictors of a known marker of psychopathology risk: parent history of disorder. Children with lower positive affectivity had an increased probability of paternal depression history in the context of higher child NA. In addition, children with lower EC and higher NA had an increased probability of maternal anxiety. Findings shed new light on the main effects and interactions that account for associations between child temperament and parent history of disorder, one of the best-established markers of an individual's own risk for future disorder, implicating reactive and regulatory traits that merit special consideration in future longitudinal work.

Parental Problem Drinking and Emerging Adult Problem Behavior: The Moderating Role of Parental Support

This study examined the relationship between parental problem drinking (maternal and paternal) and emerging adult problem behaviors (alcohol use, drug use, and antisocial behavior). In addition, the moderating role of parental support (maternal and paternal) was explored. Data were drawn from a nationally representative sample of emerging adults (N = 600; Mage = 20.00, SD = 1.42; 50% women; 62% White). Results from regression analyses of survey data indicated that both maternal problem drinking and maternal support moderated the relationship between paternal problem drinking and emerging adult alcohol use. For drug use, there was a three-way interaction between paternal problem drinking, maternal problem drinking, and maternal support. The relationship between paternal problem drinking and drug use only was significant for those who reported high maternal problem drinking and low maternal support. For antisocial behavior, there were positive relationships between paternal problem drinking and antisocial behavior and between maternal problem drinking and antisocial behavior in contexts of varying levels of parental support. Findings highlight the potential for parental support to both buffer and enhance the adverse influence of parental problem drinking across varied contexts.

Psychological and Mnemonic Benefits of Nostalgia for People with Dementia

BACKGROUND

Studies with non-clinical populations show that nostalgia increases psychological resources, such as self-esteem and social connectedness.

OBJECTIVES

Our objectives were to find out if the benefits of nostalgia in non-clinical populations generalize to people with dementia and if nostalgia facilitates recall of dementia-related information.

METHODS

All three experiments recruited participants with mild or moderate levels of dementia. Experiment 1 tested whether nostalgia (compared to control) enhances psychological resources among 27 participants. Experiment 2 used music to induce nostalgia (compared to control) in 29 participants. Experiment 3 compared recall for self-referent dementia statements among 50 participants randomized to either a nostalgia or control condition. Findings across experiments were synthesized with integrative data analysis.

RESULTS

Nostalgia (compared to control) significantly increased self-reported social connectedness, meaning in life, self-continuity, optimism, self-esteem, and positive (but not negative) affect (Experiments 1-3). Compared to controls, nostalgic participants also recalled significantly more self-referent dementia-related information (Experiment 3).

CONCLUSION

This series of experiments extends social psychological research with non-clinical populations into dementia care, providing evidence that nostalgia significantly enhances psychological resources. The finding that nostalgia increased recall of self-referent statements about dementia suggests that this emotion lends participants the fortitude to face the threat posed by their illness. The finding has potentially important clinical implications both for the development of reminiscence therapy and for facilitating adjustment to a diagnosis of dementia.

Time-specific and cumulative effects of exposure to parental externalizing behavior on risk for young adult alcohol use disorder

BACKGROUND

Previous studies indicate that parental externalizing behavior (EB) is a robust risk factor for alcohol use disorder (AUD) in their children, and that this is due to both inherited genetic liability and environmental exposure. However, it remains unclear whether the effects of exposure to parental EB vary as a function of timing and/or chronicity.

METHODS

We identified biological parents with an alcohol use disorder, drug abuse, or criminal behavior, during different periods of their child's upbringing, using Swedish national registries. Logistic regression was used to determine whether the effect of parental EB exposure during different developmental periods differentially impacted children's risk for young adult AUD (ages 19-24). In addition, we tested how multiply affected parents and/or sustained exposure to affected parents impacted risk.

RESULTS

While parental EB increased risk for young adult AUD, timing of exposure did not differentially impact risk. Having a second affected parent increased the risk of AUD additionally, and sustained exposure to parental EB across multiple periods resulted in a higher risk of young adult AUD than exposure in only one period.

CONCLUSIONS

In this well-powered population study, there was no evidence of "sensitive periods" of exposure to national registry-ascertained parental EB with respect to impact on young adult AUD, but sustained exposure was more pathogenic than limited exposure. These findings suggest developmental timing does not meaningfully vary the impact, but rather there is a pervasive risk for development of young adult AUD for children and adolescents exposed to parental EB.

Disentangling the effects of depression on trajectories of sleep problems from adolescence through young adulthood

BACKGROUND

Little is known about the differential influences of between- and within-person effects of depression as well as its long-term impacts on sleep problems in adolescents. This study aims to disentangle these differences by estimating three effects of depression (i.e., long-term, immediate, and fluctuating).

METHODS

The sample included 1345 males and 1283 females in Taiwan. In multilevel models, the between- (i.e., long-term and immediate) and within-person (i.e., fluctuating) effects were estimated by using the average and time-varying scores of depression, respectively. The interactions between long-term and the other effects were also tested to determine the moderating effects of long-term influences.

RESULTS

Significant immediate and long-term effects of depression were found for both sexes, indicating that adolescents with higher levels of depression were at increased risks for future sleep problems. For females only, the long-term effects further exacerbated the negative influences of immediate effects of depression on sleep problems. Moreover, the fluctuating effects were found to change over time in females and the influences were more pronounced in young adulthood.

LIMITATIONS

The self-reported measures of both depression and sleep problems may produce common method variance and bias the results. Our measurements were adapted from various existing scales to increase their applicability; therefore, the internal consistency was not high.

CONCLUSIONS

Our findings provide insight regarding who is at risk for sleep problems and when this risk would occur based on the effects of depression. They also highlight the importance of both immediate and long-term effects of depression on development of sleep problems.

Parental alcohol use and risk of behavioral and emotional problems in offspring

OBJECTIVE

The majority of studies that have examined parental alcohol use and offspring outcomes have either focused on exposure in the antenatal period or from clinical populations. This study sought to examine proximal and distal associations between parental alcohol use and offspring conduct problems and depressive symptoms in a population birth cohort.

METHODS

We used prospective data from a large UK based population cohort (ALSPAC) to investigate the association between parental alcohol use, measured in units, (assessed at ages 4 and 12 years) with childhood conduct trajectories, (assessed on six occasions from 4 to 13.5 years, n = 6,927), and adolescent depressive symptoms (assessed on four occasions from ~13 to ~18 years, n = 5,539). Heavy drinking was defined as ≥21 units per week in mothers and partners who drank 4+ units daily.

RESULTS

We found little evidence to support a dose response association between parental alcohol use and offspring outcomes. For example, we found insufficient evidence to support an association between maternal alcohol use at age 4 years and childhood conduct problems (childhood limited: OR = 1.00, 95% CI = .99, 1.01; adolescent onset: OR = 0.99, 95% CI = .98, 1.00; and early-onset persistent: OR = 0.99, 95% CI = .98, 1.00) per 1-unit change in maternal alcohol use compared to those with low levels of conduct problems. We also found insufficient evidence to support an association between maternal alcohol use at age 4 years and adolescent depressive symptoms (intercept: b = .001, 95% CI = -.01, .01, and slope: b = .003, 95% CI = -.03, .03) per 1-unit change in maternal alcohol use. Results remained consistent across amount of alcohol consumed (i.e., number of alcohol units or heavy alcohol use), parent (maternal self-reports or maternal reports of partner's alcohol use), and timing of alcohol use (assessed at age 4 or age 12 years).

CONCLUSIONS

There is no support for an association between parental alcohol use during childhood and conduct and emotional problems during childhood or adolescence.

Interactive Effect of Parent and Adolescent Psychiatric Symptoms on Substance Use among Adolescents in Community Treatment

Both adolescent and parent psychiatric symptoms are well-established risk factors for adolescent substance use (SU), but the ways that these symptoms interact are not well understood. This study examined the interactive effects of parent and adolescent psychiatric symptoms on adolescent frequency of alcohol and marijuana use, over and above the effects of parental SU. Seventy adolescents presenting to a community mental health center (CMHC) participated. Parent and adolescent psychiatric symptoms were measured with the brief symptom inventory (BSI) and child behavior checklist (CBCL), respectively. Hierarchical regressions revealed different patterns for adolescent alcohol and marijuana use. For alcohol, the BSI parent phobic anxiety subscale predicted increased adolescent use while the parent interpersonal sensitivity subscale predicted decreased use: the effects of these parental symptoms were strongest among adolescents with higher levels of externalizing problems on the CBCL. For marijuana, the BSI parent psychoticism subscale predicted increased adolescent use, whereas paranoid ideation predicted decreased use. Results suggest that adolescent SU treatment and assessment should attend to both adolescent and parent psychiatric symptoms.

Modeling Trajectories of Adolescent-Perceived Family Conflict: Effects of Marital Dissatisfaction and Parental Alcoholism

We evaluated the effects of marital dissatisfaction on adolescent-perceived conflict in 435 families with and without a parental history of alcoholism. On average, family conflict decreased linearly as adolescents aged. Families with an alcoholic parent demonstrated higher adolescent-reported family conflict and this effect was partially mediated by higher mother- and father-reported marital dissatisfaction. Families with higher marital dissatisfaction had greater conflict when adolescents were young (based on fathers' marital dissatisfaction) and as they aged (based on mother's marital dissatisfaction). Years in which mothers reported higher marital dissatisfaction than usual coincided with years in which adolescents reported greater family conflict. Results indicate that marital dissatisfaction has both within and between-family effects on adolescent perceptions of conflict.

Intergenerational consequences of adolescent substance use: Patterns of homotypic and heterotypic continuity

Does substance use run in families? In this article, we examine both homotypic continuity in substance use-the impact of a parent's adolescent substance use on their child's adolescent substance use-and heterotypic continuity-the impact of a parent's adolescent substance use on their child's involvement in other adolescent problem behaviors. The analysis is based on data from the Rochester Youth Development Study (Thornberry, Lizotte, Krohn, Smith, & Porter, 2003) and its intergenerational component, the Rochester Intergenerational Study (Thornberry, 2009). The initial study began with a representative sample of 7th and 8th grade students followed until Age 31, and the intergenerational study is currently following their oldest biological child from childhood through adolescence. The final sample size in the current analysis consists of 341 parent-child dyads. For fathers, their adolescent substance use predicts both homotypic and heterotypic outcomes of their child. For mothers, however, there is no evidence of intergenerational continuity for either homotypic or heterotypic outcomes. In contrast, when the parent's adult substance use is examined, the opposite pattern emerges. The mother's adult substance use is a more consistent predictor of child behavioral outcomes, but there is little evidence that the father's adult behavior matters. Thus, it appears that the answer to the question of whether or not substance use runs in families is more nuanced than typically thought. Based on these results, continuity depends both on the sex of the parent and when in the parent's life-course substance use occurs. (PsycINFO Database Record

Psychosocial problems in children of women entering substance use disorder treatment: A longitudinal study

BACKGROUND

While parental substance use disorder (SUD) has been recognized as a risk factor for child outcomes, past research seldom focused specifically on children whose mothers suffer from alcohol and drug use disorders. Are these children at risk for elevated psychosocial problems, and would such risk be reduced if maternal substance use was reduced?

AIMS

Children of substance-abusing mothers (COSAM, N=130) were compared to a demographically matched comparison sample, and examined soon after their mothers entered SUD treatment and in the 18months after treatment entry. We expected to observe elevated symptomatology among COSAM at baseline assessment, followed by a decreasing trend after maternal treatment in general, and remission in particular.

RESULTS

Children's psychosocial problems were assessed through maternal reports on the Pediatric Symptom Checklist. Soon after their mothers entered SUD treatment, COSAM exhibited significantly greater overall and clinical-level psychosocial problems than the children from the matched comparison sample. However, at the end of the 18-months study period, these two groups no longer differed in terms of problems. Results from the longitudinal growth models revealed reductions in COSAM's overall and clinical-level problems following their mothers' SUD treatment. However, these reductions were similar for all COSAM, regardless of whether their mothers relapsed or remitted.

CONCLUSION

Psychosocial problems were significantly reduced in COSAM following maternal SUD treatment, such that COSAM did not significantly differ from children from the matched comparison sample by the end of the 18-month study period.

Intergenerational continuity in parents' and adolescents' externalizing problems: The role of life events and their interaction with GABRA2

We examine whether parental externalizing behavior has an indirect effect on adolescent externalizing behavior via elevations in life events, and whether this indirect effect is further qualified by an interaction between life events and adolescents' GABRA2 genotype (rs279871). We use data from 2 samples: the Child Development Project (CDP; n = 324) and FinnTwin12 (n = 802). In CDP, repeated measures of life events, mother-reported adolescent externalizing, and teacher-reported adolescent externalizing were used. In FinnTwin12, life events and externalizing were assessed at age 14. Parental externalizing was indexed by measures of antisocial behavior and alcohol problems or alcohol dependence symptoms in both samples. In CDP, parental externalizing was associated with more life events, and the association between life events and subsequent adolescent externalizing varied as a function of GABRA2 genotype (p ≤ .05). The association between life events and subsequent adolescent externalizing was stronger for adolescents with 0 copies of the G minor allele compared to those with 1 or 2 copies of the minor allele. Parallel moderation trends were observed in FinnTwin12 (p ≤ .11). The discussion focuses on how the strength of intergenerational pathways for externalizing psychopathology may differ as a function of adolescent-level individual differences.

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.

Developmental cascade model for adolescent substance use from infancy to late adolescence

A developmental cascade model for adolescent substance use beginning in infancy was examined in a sample of children with alcoholic and nonalcoholic parents. The model examined the role of parents' alcohol diagnoses, depression and antisocial behavior in a cascading process of risk via 3 major hypothesized pathways: first, via parental warmth/sensitivity from toddler to kindergarten age predicting higher parental monitoring in middle childhood through early adolescence, serving as a protective pathway for adolescent substance use; second, via child low self-regulation in the preschool years to a continuing externalizing behavior problem pathway leading to underage drinking and higher engagement with substance using peers; and third, via higher social competence from kindergarten age through middle childhood being protective against engagement with delinquent and substance using peers, and leading to lower adolescent substance use. The sample consisted of 227 intact families recruited from the community at 12 months of child age. Results were supportive for the first 2 pathways to substance use in late adolescence. Among proximal, early adolescent risks, engagement with delinquent peers and parent's acceptance of underage drinking were significant predictors of late adolescent alcohol and marijuana use. The results highlight the important protective roles of maternal warmth/sensitivity in early childhood to kindergarten age, parental monitoring in middle childhood, and of child self-regulation in the preschool period as reducing risk for externalizing behavior problems, underage drinking, and engagement with delinquent peers in early adolescence. Specific implications for the creation of developmentally fine-tuned preventive intervention are discussed. (PsycINFO Database Record

Mental disorders and harmful substance use in children of substance abusing parents: A longitudinal register-based study on a complete birth cohort born in 1991

INTRODUCTION AND AIMS

Adverse childhood experiences and their accumulation over childhood have negative outcomes to children, yet earlier findings on the independent effect of parental substance abuse seem inconsistent. Our aims were to examine: (i) whether parental substance abuse is associated with children's mental disorders in mid-childhood (7-12 years) and mental disorders and own substance use in adolescence (13-17 years); and (ii) whether children are affected differently by a mother or father's substance abuse.

DESIGN AND METHODS

A register-based longitudinal data on a complete birth cohort of children born in Finland in 1991 (n = 65 117) and their biological parents. The children were followed until their 18^th birthday. Data were derived from the Finnish administrative registries. Bivariate and multivariate logistic regression models were used in the analysis.

RESULTS

Maternal, paternal and both parents' substance abuse were significant predictors of mental disorders and harmful substance use in children aged 13-17 years, even after controlling for other adverse childhood experiences, parental education and child's gender. Parental substance abuse predicted mental disorders in children aged 7-12 years in bivariate model but in multivariate model the association disappeared. Maternal substance abuse had stronger effect on harmful substance use in adolescent children than paternal. There were no significant interactions between substance abusing parents' gender and the child's gender.

DISCUSSION AND CONCLUSIONS

Early identification, prevention and treatment of substance abuse in families with children in primary health care, child welfare and other services are crucial in preventing intergenerational transmission of the problems associated with parental substance abuse.

Neighborhood × Serotonin Transporter Linked Polymorphic Region (5-HTTLPR) interactions for substance use from ages 10 to 24 years using a harmonized data set of African American children

This study investigated the influences of neighborhood factors (residential stability and neighborhood disadvantage) and variants of the serotonin transporter linked polymorphic region (5-HTTLPR) genotype on the development of substance use among African American children aged 10-24 years. To accomplish this, a harmonized data set of five longitudinal studies was created via pooling overlapping age cohorts to establish a database with 2,689 children and 12,474 data points to span ages 10-24 years. A description of steps used in the development of the harmonized data set is provided, including how issues such as the measurement equivalence of constructs were addressed. A sequence of multilevel models was specified to evaluate Gene × Environment effects on growth of substance use across time. Findings indicated that residential instability was associated with higher levels and a steeper gradient of growth in substance use across time. The inclusion of the 5-HTTLPR genotype provided greater precision to the relationships in that higher residential instability, in conjunction with the risk variant of 5-HTTLPR (i.e., the short allele), was associated with the highest level and steepest gradient of growth in substance use across ages 10-24 years. The findings demonstrated how the creation of a harmonized data set increased statistical power to test Gene × Environment interactions for an under studied sample.

Did the 18 Drinking Age Promote High School Dropout? Implications for Current Policy

OBJECTIVE

Disagreement exists over whether permissive minimum legal drinking age (MLDA) laws affected underage adolescents (e.g., those age 17 years with the MLDA of 18). We used MLDA changes during the 1970s and 1980s as a natural experiment to investigate how underage exposure to permissive MLDA affected high school dropout.

METHOD

MLDA exposure was added to two data sets: (a) the 5% public use microdata samples of the 1990 and 2000 censuses (n = 3,671,075), and (b) a combined data set based on the 1991-1992 National Longitudinal Alcohol Epidemiological Survey (NLAES) and the 2001-2002 National Epidemiological Survey on Alcohol and Related Conditions (NESARC; n = 16,331). We used logistic regression to model different thresholds of MLDA on high school dropout. We also estimated models conditioned on demographic variables and familial risk of developing alcohol problems.

RESULTS

Only the MLDA of 18 predicted high school dropout. Exposure was associated with 4% and 13% higher odds of high school dropout for the census and NLAES/NESARC samples, respectively. We noted greater impact on women (5%-18%), Blacks (5%-19%), and Hispanics (6%). Self-report of parental alcohol problems was associated with 40% higher odds, which equals a 4.14-point increase in dropout rate for that population.

CONCLUSIONS

The MLDA of 18 likely had a large impact on high school dropout rates, suggesting that the presence of legal-aged peers in a high school setting increased access to alcohol for younger students. Our results also suggest that policy can promote less dangerous drinking behavior even when familial risk of alcohol use disorders is high.

Parental Support, Mental Health, and Alcohol and Marijuana Use in National and High-Risk African-American Adolescent Samples

African-American adolescents experience disproportionate rates of negative consequences of substance use despite using substances at average or below-average rates. Due to underrepresentation of African-American adolescents in etiological literature, risk and protective processes associated with their substance use require further study. This study examines the role of parental support in adolescents' conduct problems (CPs), depressive symptoms (DSs), and alcohol and marijuana use in a national sample and a high-risk sample of African-American adolescents. In both samples, parental support was inversely related to adolescent CPs, DSs, and alcohol and marijuana use. CPs, but not DSs, partially mediated the relation of parental support to substance use. Results were consistent across the national and high-risk samples, suggesting that the protective effect of parental support applies to African-American adolescents from a range of demographic backgrounds.

Witnessing substance use increases same-day antisocial behavior among at-risk adolescents: Gene-environment interaction in a 30-day ecological momentary assessment study

Many young adolescents are embedded in neighborhoods, schools, and homes where alcohol and drugs are frequently used. However, little is known about (a) how witnessing others' substance use affects adolescents in their daily lives and (b) which adolescents will be most affected. The current study used ecological momentary assessment with 151 young adolescents (ages 11-15) to examine the daily association between witnessing substance use and antisocial behavior across 38 consecutive days. Results from multilevel logistic regression models indicated that adolescents were more likely to engage in antisocial behavior on days when they witnessed others using substances, an association that held when substance use was witnessed inside the home as well as outside the home (e.g., at school or in their neighborhoods). A significant Gene × Environment interaction suggested that the same-day association between witnessing substance use and antisocial behavior was significantly stronger among adolescents with, versus without, the dopamine receptor D4 seven repeat (DRD4-7R) allele. The implications of the findings for theory and research related to adolescent antisocial behavior are discussed.

Answering Developmental Questions Using Secondary Data

Secondary data analysis of large longitudinal and national data sets is a standard method used in many social sciences to answer complex questions regarding behavior. In this article, we detail the advantages of using these data sets to study developmental questions across the lifespan. First, we provide an overview of how using secondary data can increase studies' scientific integrity. Then, we detail where and how data sets can be obtained that answer specific questions. Finally, we discuss methodological issues related to using longitudinal, population data sets. These data sets can enhance science and test theories by increasing the rigor and generalizability of research to the general population, making secondary data analysis an important method to consider.

Intergenerational Transmission of Externalizing Behavior

This prospective longitudinal investigation examined the predictors of generation 2 (G2) parental substance use as related to their generation 3 (G3) offspring's externalizing behavior. The sample comprised 281 mother- or father- child (G2/G3) pairs. The results indicated that the G1/G2 (generations 1 and 2) parent-child relationship during G2's adolescence predicted externalizing behavior in the G2 young adults which correlated with G2 parental substance use. G2 parental substance use was related to subsequent G2 substance use disorders (SUDS), and to the G2/G3 parent-child relationship. The G2/G3 parent-child relationship and G2's SUDS each predicted G3 externalizing behavior. The results highlight the significance of breaking the chain of transmission of externalizing behavior across generations. Implications for policy and programs addressing the etiology of externalizing behavior in the offspring are discussed within a developmental framework.

Parental problem drinking and adolescent externalizing behaviors: The mediating role of family functioning

This study explored relationships among parental problem drinking, family functioning, and adolescent externalizing behaviors. The unique effects of maternal and paternal drinking were examined separately for girls and boys. The sample included 14-19 year old U.S. adolescents (Mage = 16.15; SD = .75; 52.5% female) and their parents. Participants completed surveys in the spring of 2007 and 2008. Structural equation modeling was used to conduct path analysis models. Results showed the distinctive and adverse effects of parental problem drinking on adolescent alcohol use, drug use, rule breaking, and aggressive behavior over time. Findings also highlighted the indirect and mediating roles of family functioning. For both girls and boys, family cohesion mediated the relationship between parental problem drinking and adolescent externalizing behaviors. For girls, adolescent-father communication predicted increased externalizing behaviors over time. These findings draw attention to the importance of exploring adolescent and parent gender when examining parental problem drinking, family functioning, and externalizing behaviors.

Gender differences in the developmental risk of onset of alcohol, nicotine, and marijuana use and the effects of nicotine and marijuana use on alcohol outcomes

OBJECTIVE

This study aimed to (a) characterize gender-specific risk of onset of alcohol, nicotine, and marijuana use developmentally; (b) investigate the effects of early-onset status and frequency of nicotine and marijuana use on alcohol outcomes, controlling for the effects of alcohol use; and (c) examine gender differences in the developmental trajectories of alcohol outcomes and the effects of nicotine and marijuana use on alcohol outcomes.

METHOD

This study conducted secondary analysis on a longitudinal study that recruited at-risk youth through fathers' drunk-driving records and door-to-door canvassing in the midwestern United States. The sample included 160 female-male sibling pairs who were assessed on substance use and Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition, diagnosis from early childhood to young adulthood.

RESULTS

Although males were at higher risk for being early-onset alcohol users, females tended to be at higher risk for initiating marijuana use at younger ages. When early onset and amount of alcohol use were controlled for, early onset of nicotine and marijuana use did not contribute to alcohol outcomes, but frequencies of nicotine and marijuana use did. We also found the associations of quantity/frequency of alcohol and marijuana use with drinking problems to be stronger among females than among males.

CONCLUSIONS

Higher frequencies of nicotine and marijuana use may contribute to worse alcohol outcomes above and beyond the effect of alcohol use. Females tend to be at higher risk than males for initiating marijuana use and meeting an alcohol use disorder diagnosis at younger ages as well as being more vulnerable to a negative impact of alcohol and marijuana use.

Risk for behavior problems in children of parents with substance use disorders

Using a high-risk community sample (N = 567), the current study examined risk for externalizing and internalizing problems in the children of parents with recovered and current substance use disorders (SUDs). This study also tested whether parenting mediated the relations between these variables. Results suggest that children of parents with current diagnoses were at elevated risk for externalizing and internalizing problems, but children of parents with recovered diagnoses were only at risk for externalizing problems. Perceived parental consistency of support mediated the relations between parent current SUD and child externalizing and internalizing problems. Disruption of the home environment may in part explain why children of parents with SUDs are at risk for externalizing and internalizing problems. However, even after parent SUD has remitted, children remain at risk for externalizing problems, suggesting multiple mechanisms by which parents confer risk for psychopathology.

Distal and proximal factors associated with aggression towards partners and non-partners among patients in substance abuse treatment

Studies of violence in substance use disorder (SUD) treatment settings typically focus on partner aggression (PA) although non-partner aggression (NPA) is also a common problem. This study examines potentially distinct paths of distal and proximal risk factors related to aggression towards non-partners (NPA) and partners (PA) among a SUD treatment sample. The sample included 176 adults reporting past-year violence. Bivariate analyses indicated several distal and proximal factors were associated with NPA and PA. According to multivariate, multiple mediation analyses youth aggression history was a factor for both NPA and PA. Alcohol and cocaine use and psychological distress were associated with NPA; marijuana use was associated with PA. There also was evidence of indirect effects of distal factors on NPA and PA. The results suggest that there may be substantially different dynamics associated with NPA and PA, and have implications for developing screening, assessment and treatment protocols targeting violence among individuals in SUD treatment.

Substance-abusing mothers and fathers' willingness to allow their children to receive mental health treatment

The purpose of this study was to examine attitudes of substance-abusing mothers and fathers entering outpatient treatment toward allowing their children to participate in individual- or family-based interventions. Data were collected from a brief anonymous survey completed by adults at intake into a large substance abuse treatment program in western New York. Only one-third of parents reported that they would be willing to allow their children to participate in any form of mental health treatment. Results of chi-square analyses revealed that a significantly greater proportion of mothers reported that they would allow their children to participate in mental health treatment (41%) compared to fathers (28%). Results of logistic regression analyses revealed even after controlling for child age, mothers were more likely than fathers to indicate their willingness to allow their children to receive mental health treatment; however, type of substance abuse (alcohol versus drug abuse) was not associated with parents' willingness to allow their children to receive treatment. Parental reluctance to allow their children to receive individual or family-based treatment is a significant barrier in efforts to intervene with these at-risk children.
