Autistic traits and alcohol use in adolescents within the general population

It has been suggested that autistic traits are associated with less frequent alcohol use in adolescence. Our study seeks to examine the relationship between autistic traits and alcohol use in a large adolescent population. Leveraging data from the IMAGEN cohort, including 2045 14-year-old adolescents that were followed-up to age 18, we selected items on social preference/skills and rigidity from different questionnaires. We used linear regression models to (1) test the effect of the sum scores on the prevalence of alcohol use (AUDIT-C) over time, (2) explore the relationship between autistic traits and alcohol use patterns, and (3) explore the specific effect of each autistic trait on alcohol use. Higher scores on the selected items were associated with trajectories of less alcohol use from the ages between 14 and 18 (b = - 0.030; CI 95% = - 0.042, - 0.017; p < 0.001). Among adolescents who used alcohol, those who reported more autistic traits were also drinking less per occasion than their peers and were less likely to engage in binge drinking. We found significant associations between alcohol use and social preference (p < 0.001), nervousness for new situations (p = 0.001), and detail orientation (p < 0.001). Autistic traits (social impairment, detail orientation, and anxiety) may buffer against alcohol use in adolescence.

Modifying the social responsiveness scale for adaptive administration

PURPOSE

The social responsiveness scale (SRS) is frequently used to quantify the autism-related phenotype and is gaining use in health outcomes research. However, it has a high respondent burden (65 items) for large-scale studies. Further, most evaluations of it have focused on the school-age form, not the preschool form. More validity evidence of shortened forms is necessary in the general population to support the broader health outcomes context of use.

METHODS

We evaluated the psychometrics of the SRS in 7030 individuals from multiple predominantly neurotypical samples in order to shorten it based on non-autistic sample metrics. Analyses included item factor analysis, differential item functioning (DIF), and multiple-group item response theory (IRT) to place the SRS items on a comparable scale, which was then simulated via computer adaptive testing (CAT) administration.

RESULTS

The SRS was broadly unidimensional with few methodological residual dependencies. On average, males had more autistic characteristics than females, and preschoolers had fewer characteristics than school-age children. The final IRT calibration included 45 items equated across forms, and each form had 11 with significant wording discrepancies and 9 items with near-identical wording that exhibited form-related DIF. The CAT simulation suggested a median of 14 items was sufficient to reach a reliable score, demonstrating its feasibility across the range of impairments.

CONCLUSION

IRT allows practitioners the ability to get highly reliable scores with fewer items than the full-length SRS. This supports the future application of the SRS in a computer adaptive testing mode in both neurotypical and ASD samples.

Reasons for alcohol use and non-use by underage U.S. autistic youth: A qualitative study

LAY ABSTRACT

What is already known about the topic? Hazardous alcohol use is when a person's drinking puts them at increased risk for negative events (e.g. health problems or car crashes). Some studies show that autistic people may be at greater risk for hazardous alcohol use than non-autistic people, while other studies have found that hazardous alcohol use is less common among autistic people than non-autistic people. We need to learn why autistic underage youth choose to drink alcohol or not. The goal of this study was to learn from US autistic youth about their attitudes and behavior related to alcohol. Forty autistic youth aged 16-20 years old were interviewed.What this article adds? Youth described several reasons why they choose to drink alcohol, including feeling like non-autistic people are more accepting when drinking, that it puts them in a less irritable or bored mood, helps them cope with problems, and helps them fit in. Reasons for not drinking alcohol include worries about becoming addicted, medication interactions, not liking the taste, fear of experiencing hangover and other health problems, and concern about acting foolish when drunk.Implications for practice, research, or policy Results reveal that hazardous alcohol use in autistic adults could have its roots in underage experiences that give autistic youth temporary relief from social anxiety, feeling lonely, and challenges with sensory processing. Right now, there are no evidence-based alcohol prevention programs in the United States for autistic people. One or more such programs may be needed. The results from this study could be used to adapt existing programs for non-autistic youth to the unique needs and risk factors of autistic youth.

Risky Alcohol Use and Comorbidity in a Swedish Adolescent Emergency Psychiatric Inpatient Population

INTRODUCTION

Underage drinking is associated with poor mental health. Early detection for risky alcohol use is recommended, although less implemented in adolescent care. The objective of this study was to investigate the prevalence of risky alcohol use and psychiatric comorbidity.

METHODS

Over a nine-month period, 145 eligible adolescents admitted to the child and adolescent emergency unit in Malmö, Sweden, were offered computerized screening with Alcohol Use Disorder Identification Test-Consumption (AUDIT-C) and Drug Use Disorders Identification Test (DUDIT).

RESULTS

Ninety-six patients (73 girls and 23 boys) agreed to participate. The most common diagnoses were affective disorder (41%) and anxiety disorder (27%). Risky alcohol use was found among 33% of the girls and 22% of the boys (p=0.45) and did not differ between diagnostic categories. There was a positive correlation between AUDIT-C and DUDIT scores (p=0.019). Among adolescents with risky alcohol use, 33% of the girls and 60% of the boys also had a risky drug use. Conversely, 47% of the girls and 60% of the boys with risky drug use also had a risky alcohol use.

CONCLUSION

In view of the poor prognosis of risky alcohol use in adolescents, alcohol and drug habits should be assessed when adolescents seek psychiatric emergency care.

Low prevalence of risk drinking in adolescents and young adults with autism spectrum problems

Individuals with Autism Spectrum Disorder (ASD) have high rates of "comorbidity". Research on concurrent substance use (disorder) in ASD, however, is scarce and findings have been inconsistent. This study aims at assessing the prevalence of risk drinking in adolescent and young adult twins with and without autism spectrum problems. Data from a Swedish longitudinal nationwide twin study were analyzed. Across three age groups of 15- (N = 10,050), 18- (N = 7,931) and 24-year-olds (N = 2,882) prevalence rates of risk drinking were compared between twins with and without an ASD proxy diagnosis and between different ASD subgroups based on comorbid proxies for attention-deficit/hyperactivity disorder (ADHD) and/or Learning Disorder (LD). ASD, ADHD, and LD were assessed using the Autism-Tics, ADHD, and other Comorbidities inventory (A-TAC), and risk drinking was captured by the Alcohol Use Disorders Identification Test (AUDIT; age 18 and 24) and another set of self-report questions (age 15). In each age group, the prevalence of risk drinking in ASD was lower than in individuals without ASD, yet increasing continuously with age. Exploratory subgroup ASD analyses showed a trend towards risk drinking being more common among individuals with co-existing ADHD or LD problems than among those without "comorbidity", although sample sizes were too small to draw any certain conclusions. This study indicates low prevalence of risk drinking in adolescents and young adults with autism spectrum problems and highlights the need for further research on alcohol use in individuals with ASD and comorbid disorders.

Systematic review of risk and protective factors associated with substance use and abuse in individuals with autism spectrum disorders

A systematic review of autism spectrum disorder and substance use and abuse was conducted based on the Preferred Reporting Items for Systematic Review and Meta-Analysis protocol guidelines (an internationally recognized standardized methodological framework for conducting systematic review). The objectives of the review were to update and extend findings reported by Arnevik and Helverschou’s review of the autism spectrum disorder and substance use literature by (1) evaluating study quality via the Mixed-Methods Appraisal Tool; (2) examining autism spectrum disorder and substance abuse diagnostic measures; (3) reporting on the prevalence of co-occurring autism spectrum disorder and substance abuse; and (4) identifying risk, protective, and positive treatment factors. Twenty-six studies on substance use and abuse in autism spectrum disorder were identified through a search of MEDLINE, PsycINFO and Google Scholar. Average study quality score was 75.4%. Prevalence rates of substance abuse among samples with autism spectrum disorder ranged from 1.3% to 36%, but due to variability in sample characteristics and diagnostic measures, a general prevalence rate could not be established. Risk and protective factors, recognized in the general population, such as familial substance abuse and comorbid externalizing disorders, and factors, which may be more likely to occur in individuals with autism spectrum disorder compared to the general population, such as few social resources (i.e. sense of social belonging, breadth of social support networks, and level of social capital) and low sensation-seeking, were identified. One intervention study was identified; however, methodological limitations preclude any conclusion regarding positive treatment factors at this time. More research, using standardized measures and comparable samples, is needed to understand risk and protective factors and to determine the prevalence of co-occurring substance abuse and autism spectrum disorder.

Lay Abstract

Symptoms characteristic of autism spectrum disorder were initially believed to protect individuals with autism spectrum disorder from developing substance abuse. However, recent studies suggest that up to 36% of individuals with autism spectrum disorder may have a co-occurring issue with substance abuse. In addition, substance abuse may worsen the difficulties with daily functioning some individuals with autism spectrum disorder experience. It is important to understand occurrence rates, and risk, protective and positive treatment factors of co-occurring autism spectrum disorder and substance abuse in order to promote the best possible support for this special population. This review aimed to find and synthesize evidence regarding risk, protective and treatment factors, and determine a general prevalence rate of co-occurring autism spectrum disorder and substance abuse from all studies on substance use and abuse in individuals with autism spectrum disorder. The review also aimed to assess study quality and identify a diagnostic measure for substance abuse in individuals with autism spectrum disorder. Twenty-six studies on substance use and abuse in autism spectrum disorder were included in the review. The rates of substance abuse among those with autism spectrum disorder identified by included studies ranged from 1.3% to 36%, but due to large differences in study methods, a general prevalence rate could not be determined. Risk and protective factors, recognized in the general population, such as familial substance abuse and co-occurring mental health issues, and factors which may be more likely to occur in individuals with autism spectrum disorder, such as limited social resources and low sensation-seeking, were identified. No diagnostic measures specific to individuals with autism spectrum disorder and substance abuse were identified. This review identified only one exploratory study on an adapted intervention for co-occurring autism spectrum disorder and substance abuse. However, there were many methodological challenges in this study that limit the conclusions that can be drawn from the data. More research, using consistent methods, is needed to understand risk and protective factors and to determine the prevalence of substance abuse among individuals with autism spectrum disorder. The potential for co-occurring autism spectrum disorder and substance abuse should be considered by professional working in both autism spectrum disorder and substance abuse services, as finding suggests substance abuse is possible among individuals with autism spectrum disorder and may occur more frequently than previously believed. In addition, autism spectrum disorder and substance abuse service providers should be sensitive to specific risk and protective factors identified by the review that may impact substance abuse course and outcomes.

Autistic traits in mentalization-based treatment for concurrent borderline personality disorder and substance use disorder: Secondary analyses of a randomized controlled feasibility study

Autism is suggested to be a dimensional construct and often represents a comorbid state. However, research on the clinical implications of the presence of autistic traits is scarce. This study aimed to investigate the impact of subclinical autistic traits in mentalization-based treatment (MBT) for concurrent borderline personality disorder (BPD) and substance use disorder (SUD). Based on the data of a randomized controlled feasibility study by Philips, Wennberg, Konradsson, and Franck (2018), secondary analyses were conducted. It was tested, if patients' (N = 46) levels of autistic traits were associated with treatment outcome measured in the course of and after treatment using interviews and self-report measures. Participants' autistic traits were not associated with the change in the severity of BPD throughout and at the end of the treatment. However, results showed associations between autistic traits and the change in patients' consumption of alcohol in the course of MBT. Furthermore, there was an association between autistic traits and the change in mentalizing capacity at the end of MBT, indicating that elevated autistic traits were associated with an improvement in mentalizing capacity. Autistic traits on a subclinical level do not appear to be a complicating factor in MBT for concurrent BPD and SUD. On the contrary, in terms of mentalizing capacity autistic traits might be associated with a larger potential for improvement or facilitate treatment outcome. Further research is needed to explore the role of higher autistic traits in treatment of this special patient group.

Factors associated with different smoking status in European adolescents: results of the SEYLE study

Early onset and long-term smoking are associated with physical and psychological health problems. The aim of the presented analysis was to investigate risk and influencing factors for different smoking status in a big sample of European adolescents. In the context of the "saving and empowering young lives in Europe" (SEYLE) study we surveyed 12,328 adolescents at the age of 13-17 from 11 countries. The survey took place in a school-based context using a questionnaire. Overall 58% reported the onset of ever-smoking under the age of 14 and 30.9% smoke on a daily basis. Multinomial logistic regression model showed significant positive associations between adolescent smoking and internalizing problems (suicidal behavior, direct self-injurious behavior, anxiety), externalizing problems (conduct problems, hyperactivity, substance consumption) and family problems (parental substance consumption, broken home). Our data show that smoking among adolescents is still a major public health problem and adolescents who smoke are at higher risk for mental problems. Further, adolescent smoking is associated with broken home families and parental behaviors. Therefore, early preventive measures are necessary not only for adolescents, but also for their parents.

Associations between neurodevelopmental disorders and factors related to school, health, and social interaction in schoolchildren: Results from a Swedish population-based survey

BACKGROUND

Children and adolescents with autism spectrum disorder (ASD) or attention-deficit/hyperactivity disorder (ADHD) are more likely to be surrounded by different risk factors. In order to work preventively with decreasing ADHD and ASD symptoms, there is a need of more knowledge concerning risk factors.

OBJECTIVE

This study aimed to investigate school, health, lifestyle and social interactions association with autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) among schoolchildren aged 6-17 years.

METHODS

Data for 18,416 children and adolescents aged 6-17 years in the county of Värmland, Sweden, from the school year 2012/2013 and 2013/2014 were obtained from the Student Health Database, which includes information on health examinations by school nurses and self-reported information of mental and physical health, social relations, physical activity, and school conditions.

RESULTS

Of all participants, 2.4% reported only ADHD and 1.6% reported only ASD. The results confirmed that ADHD or ASD was significantly associated with worse school experiences, lower socioeconomic status, less physical activity, more substance use, weaker social network and more impairments than those without ADHD or ASD.

CONCLUSIONS

Knowledge of risk or protective factors during school years is needed to develop interventions to reduce symptoms of neurodevelopmental disorders in children and adolescents.

A Pilot Study for Understanding the Perceptions of Australian General Practitioners Regarding Psychopharmacology for Children With Autism Spectrum Disorders

BACKGROUND

General practitioners (GPs) are increasing involved in the care of children with autism spectrum disorders (ASDs), and prescribe and/or manage psychotropic medications for these children. Few published reports of perceptions of GPs regarding use of these medications exist in the literature.

OBJECTIVE

Qualitative analysis of comments by 177 GPs regarding psychopharmacology use in children with ASDs.

METHODS

A postal questionnaire survey containing both close- and open-ended questions was conducted in New South Wales, Australia.

RESULTS

Respondent GPs were more likely to be females graduated from Australian medical schools and reported an interest either in child or in mental health. The respondents demonstrated good understanding of the issues surrounding psychopharmacology use in children with ASD based on contemporary literature on this topic. The main themes included concerns regarding medication safety, evidence for their use, and role of these medications as an adjuvant to behavior management. GPs reported a lack of experience of these medications, and would often prescribe only under the supervision of specialists. GPs with greater confidence and involvement with children of ASDs prescribed more medications; whereas GP reporting more concerns with regard to medications prescribed less.

CONCLUSION

Respondent GPs have good understanding of psychotropic medications but need support from specialists for managing these medications in children with ASDs. Future larger studies should explore the utility of collaborative models of care for GPs to work in close partnerships with specialists.
