Twala B, Molloy E. On effectively predicting autism spectrum disorder therapy using an ensemble of classifiers. Sci Rep 2023; 13:19957. [PMID: 37968315 PMCID: PMC10651853 DOI: 10.1038/s41598-023-46379-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/13/2023] [Accepted: 10/31/2023] [Indexed: 11/17/2023] Open
Abstract
An ensemble of classifiers combines several single classifiers to deliver a final prediction or classification decision. An increasingly provoking question is whether such an ensemble can outperform the single best classifier. If so, what form of ensemble learning system (also known as multiple classifier learning systems) yields the most significant benefits in the size or diversity of the ensemble? In this paper, the ability of ensemble learning to predict and identify factors that influence or contribute to autism spectrum disorder therapy (ASDT) for intervention purposes is investigated. Given that most interventions are typically short-term in nature, henceforth, developing a robotic system that will provide the best outcome and measurement of ASDT therapy has never been so critical. In this paper, the performance of five single classifiers against several multiple classifier learning systems in exploring and predicting ASDT is investigated using a dataset of behavioural data and robot-enhanced therapy against standard human treatment based on 3000 sessions and 300 h, recorded from 61 autistic children. Experimental results show statistically significant differences in performance among the single classifiers for ASDT prediction with decision trees as the more accurate classifier. The results further show multiple classifier learning systems (MCLS) achieving better performance for ASDT prediction (especially those ensembles with three core classifiers). Additionally, the results show bagging and boosting ensemble learning as robust when predicting ASDT with multi-stage design as the most dominant architecture. It also appears that eye contact and social interaction are the most critical contributing factors to the ASDT problem among children.

Abstract
PURPOSE We explored factors predicting repeated or hazardous alcohol use among autistic and non-autistic U.S. youth ages 16 to 20 years. METHODS Autistic (n = 94) and non-autistic (n = 92) youth completed an online survey. By design, half of each group reported past-year alcohol use. We compared drinking patterns for autistic and non-autistic youth, and within each group between abstinent or infrequent drinkers (0-1 drinking episodes in past year) versus those who drank 2 + times in past year. RESULTS Autistic (vs. non-autistic) youth who drank did so less frequently and consumed fewer drinks per occasion. However, 15% of autistic youth who drank in the past year reported heavy episodic drinking and 9.3% screened positive for AUDIT-C hazardous drinking. For autistic youth only, a diagnosis of depression, bullying or exclusion histories were positively associated with drinking 2 + times in the past year. Autistic youth who put more effort into masking autistic traits were less likely to report drinking 2 + times in the past year. As compared to non-autistic youth, autistic participants were less likely to drink for social reasons, to conform, or to enhance experiences, but drank to cope at similar rates. CONCLUSION Repeated and hazardous underage alcohol occur among autistic youth. Targeted prevention programs designed to address the specific drinking profiles of autistic youth are needed.

Abstract
Research highlights the increasing overlap of autism spectrum disorder and substance use disorders in young people. However, no behavioral treatments exist addressing this comorbidity despite great need. A team of clinicians developed an integrated behavioral protocol addressing substance use in youth with autism spectrum disorder. The multidisciplinary team developed 12 youth, 7 parent, and 3 joint modules based on established evidence-based therapies shown to have effectiveness separately addressing autism spectrum and substance use. Two cases are discussed to illuminate this integrated intervention. Adaptations to the protocol were made during feedback from patients and their parents. Further research is needed to determine the effectiveness of this preliminary protocol.

Abstract
PURPOSE Substance misuse may be elevated in some individuals with autism spectrum disorder (ASD). As yet, however, little is known about the association between autistic traits (AT) and substance use/misuse in adults. This study examined the association between AT and binge drinking (BD) among individuals in Japan. METHODS Data were analyzed from 1452 individuals aged 18 and above collected during an online survey in February 2021. Self-reported information was obtained on BD assessed as consuming 5 or more (males) or 4 or more (females) drinks containing any kind of alcohol within a 2-h period. AT were assessed with the Japanese version of the Autism Spectrum Quotient - the AQ-J-10. Logistic regression analysis was used to examine associations. RESULTS The prevalence of past-month BD was significantly higher in individuals with AT compared to those without AT (42.7% > 27.6%). In a fully adjusted analysis that controlled for mental health (anxiety, depression) and attention-deficit/hyperactivity disorder symptoms, individuals with AT had significantly higher odds for BD once a week or more often (OR: 1.54, 95%CI: 1.04-2.29). AT were also associated with significantly higher odds for BD among women (OR: 2.27, 95%CI: 1.08-4.76), and those aged 18-34 (OR: 2.37, 95%CI: 1.09-5.18) and aged 60 and above (OR: 2.15, 95%CI: 1.02-4.53). CONCLUSION Individuals with AT have higher odds for BD. Increased efforts to detect alcohol use/misuse in adults with AT and AT in adults misusing alcohol may be efficacious in efforts to manage symptoms and eliminate harmful alcohol misuse.

Abstract
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.

Abstract
BACKGROUND While several studies have revealed that neurodevelopmental disorders have a high probability of overlapping with substance use disorders, the effects of neurodevelopmental disorders on the courses of substance use disorders have hardly been examined. METHODS This study targeted 637 alcohol-dependent individuals who received inpatient treatment and whose drinking situations were followed for 12 months after hospital discharge using mailed questionnaires. The comorbidity of psychiatric disorders and the characteristics associated with the neurodevelopmental disorders were assessed using several measurements at the time of hospital admission. The effects of neurodevelopmental disorders on the drinking courses of the subjects were then estimated. RESULTS The presence of a current depressive episode or any anxiety disorder significantly lowered the abstinence rates during the follow-up period (p = 0.0195 and p = 0.0214, respectively). ADHD traits as assessed using the ADHD Self-report Scale (ASRS) predicted a significantly poorer abstinence rate (p = 0.0296). Similarly, attention-deficit characteristics assessed objectively through interviews predicted a significantly lower abstinence rate (p = 0.0346), and a sensitivity analysis enhanced these results (p = 0.0019). When the drinking patterns were classified into three groups, the subjects with attention-deficit characteristics had a significantly higher rate of "Recurrence" and lower rates of "Abstinence" and "Controlled drinking" (p = 0.013). In a multivariate proportional hazards analysis, the ASRS score was significantly correlated with the re-drinking risk (p = 0.003). CONCLUSION ADHD traits had significant effects on not only abstinence rates, but also on drinking pattern. The presence of ADHD traits, especially attention-deficit characteristics, influenced the drinking courses of alcohol-dependent individuals after hospital treatment.

Abstract
BACKGROUND AND OBJECTIVES Recent work highlights an increase in the overlap of autism spectrum disorder (ASD) and substance use disorder (SUD). Little is known about the presence of ASD symptoms in SUD-treatment-seeking populations. METHODS The informant-rated Social Responsiveness Scale-2 (SRS-2) was completed at intake to an outpatient SUD clinic for youth aged 16-26 (N = 69). Comparisons were made between those with elevated SRS-2 scores on demographic, psychiatric, and substance use variables. RESULTS Parents of sixty-nine patients with SUD completed the SRS-2. Fourteen (20%) (average age 18.7 ± 2.5) had elevated SRS-2 Total T-scores (≥66) and 55 (average age 18.1 ± 2.8) had non-clinical SRS-2 Total T-scores. There were few differences between groups; however, those with elevated SRS-2 Total T-scores were more likely to have a stimulant use disorder (odds ratio [OR] = 7.59, 95% confidence interval [CI] = 0.77, 101.88; p = 0.05) or an opioid use disorder (OR = 5.02, 95% CI = 0.59, 43.27; p = 0.08) than patients with normal SRS-2 Total T-scores as well as alcohol use in the week prior to intake. DISCUSSION AND CONCLUSIONS A significant proportion of treatment-seeking SUD outpatients suffer from clinically elevated autistic traits. These findings highlight the importance of assessing for autistic traits in SUD treatment settings yet additional research is needed to determine if these findings are specific to the presence of ASD or secondary to sequelae of specific SUD presentations. SCIENTIFIC SIGNIFICANCE This study is, to our knowledge, the first to have examined the prevalence, morbidity, or clinical characteristics, associated with ASD symptoms in a SUD-specific population.

Abstract
BACKGROUND Autistic individuals might be more likely to misuse substances than non-autistic individuals. Better understanding of these patterns can help clinicians identify strategies to reduce substance use, protecting physical and mental health. The aim of this study was to compare the experiences of substance use between autistic and non-autistic adolescents and adults. METHODS This study is a mixed-methods study, including both quantitative (closed-ended questions) and qualitative (one open-ended question) online assessments. Data were collected as part of a larger study, the Autism and Physical Health Survey, in which we administered an anonymised, online questionnaire to autistic and non-autistic individuals aged 16-90 years. In the present study, we investigated data on substance use or misuse, using two overlapping but separate samples from the survey (one sample with complete quantitative responses and one sample with complete qualitative responses). Binary measures of substance use were investigated using unadjusted and adjusted binomial logistic regression models. Content analysis was used to compare experiences of autistic and non-autistic adolescents and adults. We used Fisher's exact tests to assess differences in frequency of reporting particular qualitative themes and subthemes. FINDINGS Survey recruitment was done between Feb 7, 2018, and Aug 26, 2019. At the end of the recruitment, 3657 individuals had accessed the survey. After excluding duplicates as well as participants with missing or incomplete responses, we had data from 2386 participants (1183 autistic and 1203 non-autistic participants; 1571 female and 815 male participants) for the quantitative analyses and data from 919 participants (429 autistic and 490 non-autistic participants; 569 female and 350 male participants) in the qualitative analyses. The samples for the quantitative and qualitative analyses were predominantly composed of female individuals, White individuals, UK residents, and those without intellectual disability. Autistic individuals were less likely than non-autistic individuals to report consuming alcohol regularly (16·0% of autistic individuals vs 22·2% of non-autistic individuals; adjusted model: odds ratio [OR] 0·69, 95% CI 0·55-0·86; p=0·0022) or binge-drinking (3·8% vs 8·2%; adjusted model: OR 0·38, 0·26-0·56; p<0·0001). Autistic male participants were less likely than non-autistic male participants to report ever having smoked (50·8% of autistic male participants vs 64·6% of non-autistic male participants; adjusted OR 0·50; 0·32-0·76; p=0·0022) or ever using drugs (35·4% vs 52·7%; adjusted OR 0·53; 0·35-0·80; p=0·0022). Regarding our qualitative analyses, among participants who reported a specific motivation for drug use, compared with non-autistic individuals, autistic individuals were nearly nine times more likely to report using recreational substances to manage behaviour (OR 8·89, 2·05-81·12; p=0·0017) and more likely to report using recreational substances to manage mental health symptoms (OR 3·08, 1·18-9·08; p=0·032). Autistic individuals were also more likely to report vulnerability associated with substance use (OR 4·16, 1·90-10·05; p=0·00027), including childhood use of drugs and being forced or tricked into using drugs. INTERPRETATION Autistic individuals might be less likely than non-autistic individuals to report engaging in substance misuse. They also report using drugs to self-medicate. Clinicians should be aware of vulnerability linked to substance use among autistic patients and should work cooperatively with patients to effectively manage autistic and comorbid symptoms.

Abstract
LAY ABSTRACT Alcohol use and misuse are associated with a variety of negative physical, psychological and social consequences. The limited existing research on substance use including alcohol use in autistic adults has yielded mixed findings, with some studies concluding that autism reduces the likelihood of substance use and others suggesting that autism may increase an individual's risk for substance misuse. This study investigated demographic and psychological predictors of alcohol use and misuse in a sample of 237 autistic adults. An online survey was used to obtain data on demographic information, autistic traits, depression, generalised anxiety, social anxiety, mental well-being, social camouflaging and alcohol use. The sample was divided into three groups (non-drinkers, non-hazardous drinkers and hazardous drinkers) in order to investigate associations between alcohol use and demographic factors, autistic traits, mental health variables and social camouflaging. Our results demonstrated a U-shaped pattern among autistic adults, with non-drinkers and hazardous drinkers scoring higher than non-hazardous drinkers on levels of autistic traits, depression, generalised anxiety and social anxiety. Autistic non-drinkers were less likely to be male and had more autistic traits. Gender and level of autistic traits may be the most significant factors in predicting alcohol use in the autistic community.

Abstract
PURPOSE OF REVIEW Although treatment algorithms and parameters for best practice are readily available for all major syndromes of psychiatric impairment, the occurrence of psychiatric syndromes in individuals with intellectual and developmental disability (IDD) invokes serious contextual challenges for interpretation of symptoms, diagnosis, and optimization of treatment, both for clinicians and for the service sectors in which care and support of individuals with IDD are delivered. Recognizing that there exist very few definitive resources for best practice under the circumstance of this form of "dual diagnosis," the Missouri Department of Mental Health convened an expert panel to conduct a focused review and synthesis of the relevant scientific literature from which to develop guidance in the form of decision support to clinicians. This article summarizes the findings for three of the most common and impairing clusters of psychiatric symptoms that co-occur with IDD-aggression, depression, and addictions. RECENT FINDINGS Individuals with IDD are at high risk for the development of psychiatric symptoms (PS), which often manifest uniquely in IDD and for which evidence for effective intervention is steadily accruing. Interventions that are commonly implemented in the IDD service sector (e.g., functional communication training and positive behavioral support planning) are capable of mitigating severe behavioral impairment, yet rarely invoked when dual diagnosis patients are seen in the psychiatric service sector. Conversely, state-of-the-art interventions for traumatic stress, pharmacotherapy, and psychotherapy have proven capable of improving behavioral impairments in IDD but are typically restricted to the psychiatric service sector, where there exist significant barriers to access for patients with IDD, including limitations imposed by diagnostic eligibility and practitioner experience. Bridging these gaps in knowledge and clinical capacity across the respective IDD and PS service sectors should be of very high priority in strategizing the care and support of IDD patients with serious co-occurring psychiatric conditions.

Abstract
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.

Helverschou SB, Brunvold AR, Arnevik EA. Treating Patients With Co-occurring Autism Spectrum Disorder and Substance Use Disorder: A Clinical Explorative Study. SUBSTANCE ABUSE-RESEARCH AND TREATMENT 2019; 13:1178221819843291. [PMID: 31024216 PMCID: PMC6472168 DOI: 10.1177/1178221819843291] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 03/08/2019] [Accepted: 03/15/2019] [Indexed: 12/04/2022]
Abstract
Background: Substance use disorders (SUDs) have been assumed to be rare in individuals
with autism spectrum disorder (ASD). Recent research suggests that the rates
of SUD among individuals with ASD may be higher than assumed although
reliable data on the prevalence of SUD in ASD are lacking. Typical
interventions for SUD may be particularly unsuitable for people with ASD but
research on intervention and therapy are limited. Methods: This study addresses ways of improving services for individuals with ASD and
SUD by enhancing the competence of professionals in ordinary SUD outpatient
clinics. Three therapists were given monthly ASD education and group
supervision. The participants were ordinary referred patients who wanted to
master their problems with alcohol or drugs. Four patients, all men
diagnosed with ASD and intelligence quotient (IQ) ⩾ 70 completed the
treatment. The participants were given cognitive behavioural therapy (CBT)
modified for their ASD over a minimum of 10 sessions. The therapies lasted
between 8 and 15 months. Standardised assessments were conducted pre- and
post-treatment. Results: Post-treatment, 2 participants had ended their drug and alcohol abuse
completely, 1 had reduced his abuse, and 1 still had a heavy abuse of
alcohol. Physical well-being was the most prevalent reported positive aspect
of drug or alcohol use, whereas the experience of being left out from social
interaction was the most frequent negative aspects of intoxication. Conclusions: CBT may represent a promising treatment option for individuals with ASD and
SUD. The results suggest that patients’ symptoms can be reduced by providing
monthly ASD education and group supervision to therapists in ordinary SUD
outpatient clinics. This group of patients need more sessions than other
client groups, the therapy has to be adapted to ASD, ie, direct,
individualised, and more extensive. Moreover, the patients need
psychoeducation on ASD generally, social training, and support to organise
several aspects of their lives and some patients need more support than can
be provided in an outpatient clinic.

Abstract
Individuals with autism spectrum disorder (ASD) frequently display intensely repetitive, restricted thoughts, and behaviors. These behaviors have similarities to compulsions and/or obsessions in obsessive compulsive disorder (OCD) and are primarily treated with behaviourally-based interventions and serotonin uptake inhibitors (SSRIs). Due to the lack of treatment responses in many cases, however, new treatments are being sought. Here we report beneficial effects of treatment with liraglutide, a glucagon-like peptide-1 (GLP-1) analog, on severe obsessive food craving, binge eating, weight gain, and behavioral problems in an adolescent male with infantile autism and moderate intellectual impairment. Liraglutide treatment reduced weight and unwanted behavior seemingly by preventing food-related repetitive thoughts and compulsions. Our report provides clinical evidence that GLP-1 signaling pathway may represent a novel target for treating food-related behavioral problems and aggressive behavior in ASD.

Front Psychiatry 2019; 10:911.

Abstract
Autism spectrum disorders (ASDs) are known to be associated with an increased risk of aggression and challenging behavior. In this study, we have mapped the externalizing history of a nationally representative cohort of young violent offenders with ASD, compared with offenders without ASD. Two hundred and sixty-nine violent offenders were assessed for prevalence of ASD, and participated in a thorough assessment of previous externalizing problems and criminal history. Twenty-six offenders met consensus clinical DSM-IV criteria for ASD and they were compared to offenders without ASD from the same cohort. Overall, we found a very high prevalence of externalizing and antisocial behaviors in the history of these offenders and there were few differences between the groups. Placements in foster homes were overrepresented in the ASD group and the ASD-offenders had significantly more often been diagnosed with a neurodevelopmental disorder (i.e. ASD or ADHD) by a clinician before the study. At index conviction, ASD offenders were overrepresented in sex crimes with a child victim. Though offenders without ASD had more previous convictions, in particular drug crimes, we found no difference in terms of total number of prosecuted crimes. Substance use disorders were more common among offenders without ASD. The ASD offenders scored higher compared to the non-ASD offenders on the Affective facet of the Psychopathy Checklist-Revised (PCL-R) but there were no differences in terms of total PCL-R scores. Our results provide important knowledge of the developmental history of offenders with ASD. Though this is a small and atypical phenotype it poses significant challenges to the criminal justice system and we need to understand more of it to be able to prevent these individuals from committing crimes but also to provide a fair judicial treatment, to assess exculpatory factors and improve our forensic treatment models.
