Change in autism symptoms and maladaptive behaviors in adolescence and adulthood: the role of positive family processes

Predictors of Aggression, Disruptive Behavior, and Anger Dysregulation in Youths with Autism Spectrum Disorder

Youth with autism spectrum disorder (ASD) often experience difficulties related to aggression, disruptive behavior, and regulation of emotions that precipitate these behaviors (i.e., anger). The extent to which aggression, disruptive behaviors, and anger dysregulation are correlated with distinct or overlapping factors has not yet been explored. The present study examined whether aspects of participant demographics, individual youth functioning, caregiver stress, and family warmth contributed to youth aggression, disruptive behavior, and anger dysregulation. Participants were caregivers of 511 youths with ASD. Analyses revealed that significant proportions of variance in aggression, disruptive behaviors, and anger dysregulation were accounted for by shared variables pertaining to demographics, the individual youth, and caregiver stress. Implications of treatment and future research are discussed.

Autism Severity and its Relationship to Disability

Autism severity is currently defined and measured based exclusively on the severity levels of the two core symptom domains: social-communication and restricted or repetitive patterns of behaviors and interests. Autistic individuals, however, are often diagnosed with other medical, developmental, and psychological co-occurring conditions. These additional challenges such as intellectual disability, limited expressive and/or receptive language, and anxiety disorders, can have a tremendous impact on the day-to-day lives of autistic individuals, for both their adaptive functioning as well as their sense of wellbeing. Furthermore, the initial presentation of core symptoms and their likelihood of changing over time are influenced by the presence of such co-occurring conditions. In order to truly understand how a person's autism impacts their life, both core symptoms as well as other challenges should be considered. This approach was recently taken by The Lancet Commission on the future of care and clinical research in autism, which proposed the term "profound autism" for a subgroup of individuals presenting with high core symptom severity, co-occurring intellectual disability, and little or no language, who require extensive long-term care. Considering other individual factors such as daily living skills, specific support needs and environmental resources would also enhance the evaluation of disability in autistic individuals. As currently employed in the assessment of intellectual disability, a multidimensional approach to autism could provide a more comprehensive system for classification of impairment. At present, however, there is no formal way to designate the combined effect of these different aspects of autism on a person's life. A comprehensive outlook that acknowledges impairments, capabilities, co-occurring conditions, and environmental factors would be useful for identifying subgroups of individuals as well as for determining individual needs and strengths in clinical assessments. Lay Summary: The severity of a person's autism is currently defined based on the severity of their core autism symptoms: impaired social-communication and the presence of restricted or repetitive patterns of behaviors and interests. But autistic people often face additional challenges such as intellectual disability, epilepsy, and anxiety disorder, that considerably impact their everyday life, wellbeing, and the need for support. A more complete view of autism severity, one that includes core symptoms as well as additional challenges, could help identify meaningful sub-groups of autistic individuals and could be useful in clinical care.

Factors Impacting Parental Quality of Life in Preschool Children on the Autism Spectrum

This study examined connections between parental quality of life (QoL) and features of children (autism severity, cognitive ability, behavioral profile, and sociodemographic factors). Parents of 97 children attending an autism-specific preschool completed the Quality of Life in Autism, Vineland Adaptive Behavior Scales and Child Behavior Checklist. The Autism Diagnostic Observation Schedule and Mullen Scales of Early Learning were also administered. Reduced restrictive/repetitive behavior and higher socialization and play/leisure scores were associated with better parental QoL. Better behavioral regulation and attention also predicted better QoL, as did stronger communication and reduced internalising behaviours. Findings indicate that a child's level of autism specific traits, adaptive functioning and behavioral profile has greater impact on parental QoL than cognitive level.

Parental Expressed Emotion and Behavioural Outcomes in Autistic Children and Adolescents: A Systematic Review

Growing interest in the links between parent-child relationships and child behavioural presentations in families of autistic children has led to an increased use of the Five Minute Speech Sample (FMSS) measure of parental expressed emotion (EE) in autism research. This review focuses on studies exploring the relationships between parental EE and behavioural outcomes in autistic children. Electronic searches of six databases and grey literature wielded eight studies that met eligibility criteria. Study designs were a mixture of cross-sectional and longitudinal and quality of studies was variable. Parental criticism was largely positively related to, and showed some predictive value for, child behaviour problems. Warmth was mostly negatively related to, and showed some predictive value for, child behaviour problems. Preliminary evidence from one study showed paternal warmth to be significantly related to child behaviours, whilst child behaviours were also significantly related to paternal warmth, suggesting a bidirectional relationship. Analysis of additional EE components produced variable results, however parental stress and depressive symptoms were consistently related to child behaviour, and preliminary evidence suggests a possible role of maternal education level and family cohesion. Outcomes were variable across FMSS coding systems and greater consistency in their application is needed in future research. The current findings suggest that parental EE has an important relationship with child behaviour and future intervention efforts may benefit from aiming to reduced EE in order to improve child outcomes.

Sibling Relationships in Families of Autistic and Typical Children: Similarities and Differences in the Perspectives of Siblings and Mothers

This study investigates mothers' and siblings' perspectives regarding similarities and differences in siblingships with and without autism. Twenty-nine typical children (Mage = 8.78 years, SD = 2.05) whose younger siblings have a diagnosis of autism and their mothers constituted the 'autism group.' Forty-six typical children (Mage = 9.12 years, SD = 2.06) with younger typical siblings and their mothers constituted the 'typical group'. Children and mothers completed the Sibling Relationship Questionnaires and were interviewed. Children's reports illustrated similarities in sibling relationships across groups, with no between-group differences in overall warmth, conflict, rivalry, or relative power in the sibling relationship. Mothers of autistic children reported their children to have less warmth and closeness (F(1,72) = 5.63, p = .02, η2 = .073) and less conflict (F(1,72) = 6.66, p = .012, η2 = .085) with their siblings than mothers of typical children. More disagreement was found between mothers and children in the autism group than in the typical group. Mothers and children reported less intimacy and less quarreling between the siblings in the autism group than in the typical group. The qualitative analysis suggests that siblings focused on the present experience, while mothers also referred to processes in the sibling relationship. Interviewees in the autism group referred to various specificities in the siblingships without explicitly using the term "autism". The findings highlight a typical-like experience for siblings of autistic children. At the same time, mothers' perspectives emphasize differences and challenges in siblingships, reporting a pattern of decreased involvement. It is important to consider both perspectives in research and clinical work with families of autistic children.

Impact of the Great Recession on Adults With Autism and Their Mothers

Autistic individuals and their families are at risk for poor outcomes in employment and mental health and may be vulnerable to long-term effects of broader societal conditions. The aim of the current longitudinal study was to understand the impact of the Great Recession of 2007-2009 on autistic individuals and their mothers (N = 392). Hierarchical linear modeling (HLM) results indicated that problem behavior of autistic adults increased in the years following the recession. The rate at which autistic individuals moved away and lived separately from their mothers also slowed during the recession. Mothers experienced significantly higher levels of depressive symptoms postrecession, compared to prerecession. In many other respects, the autistic individuals and their mothers did not experience negative outcomes, suggesting resilience and a strong safety net. These included the physical health and vocational/employment status of the autistic adults and their mothers. Results point to specific areas of vulnerability of autistic individuals and their mothers during the economic downturn, as well as a broad pattern of resilience in these families.

Autism through midlife: trajectories of symptoms, behavioral functioning, and health

BACKGROUND

This study describes change in autism symptoms, behavioral functioning, and health measured prospectively over 22 years. Most studies tracking developmental trajectories have focused on autism during childhood, although adulthood is the longest stage of the life course. A robust understanding of how autistic people change through midlife and into older age has yet to be obtained.

METHODS

Using an accelerated longitudinal design with 9 waves of data, developmental trajectories were estimated from adolescence through midlife and into early old age in a community-based cohort (n = 406). The overall aim was to determine whether there were age-related increases or decreases, whether the change was linear or curvilinear, and whether these trajectories differed between those who have ID and those who have average or above-average intellectual functioning. Subsequently, the slopes of the trajectories were evaluated to determine if they differed depending on age when the study began, with the goal of identifying possible cohort effects.

RESULTS

There were significant trajectories of age-related change for all but one of the measures, although different measures manifested different patterns. Most autism symptoms improved through adulthood, while health worsened. An inverted U-shaped curve best described change for repetitive behavior symptoms, activities of daily living, maladaptive behaviors, and social interaction. For these measures, improved functioning was evident from adolescence until midlife. Then change leveled off, with worsening functioning from later midlife into early older age. Additionally, differences between autistic individuals with and without ID were evident. Although those who have ID had poorer levels of functioning, there were some indications that those without ID had accelerating challenges in their aging years that were not evident in those with ID - increases in medications for physical health problems and worsening repetitive behaviors.

CONCLUSIONS

Meeting the needs of the increasingly large population of autistic adults in midlife and old age requires a nuanced understanding of life course trajectories across the long stretch of adulthood and across multiple domains. Given the heterogeneity of autism, it will be important not to generalize across sub-groups, for example those who are minimally verbal and those who have above-average intellectual functioning.

Longitudinal studies of challenging behaviours in autistic children and adults: A systematic review and meta-analysis

Autistic children and adults are at increased risk of showing behaviours that may be described as challenging, however, little is known about whether or how these behaviours may change over time. Given the profound impact that challenging behaviour can have on both the autistic individual and their support network, it is critical that the trajectory of challenging behaviours be better understood. This systematic review and meta-analysis identified and synthesised observational longitudinal studies of challenging behaviour in autistic individuals. Fifty-six studies were included in the systematic review, and the effect sizes of 37 independent samples arising from 34 of these reports were examined through meta-analysis. Crucially, across the 37 samples, scores on the measures of challenging behaviour reduced by a small, yet significant, extent over time. Although age of the sample at baseline assessment did not moderate the effect, the time between the baseline assessment and final follow-up and age at final follow-up both moderated the magnitude of the effect, with challenging behaviour scores reducing to a larger extent in (a) studies with longer intervals between baseline and final follow-up and (b) studies with older samples at follow-up. The results from the current systematic review and meta-analysis have both theoretical and practical implications for understanding challenging behaviour over time in autistic individuals. Avenues for future research are also highlighted that may allow better understanding, and therefore support of, challenging behaviour in autistic individuals.

Autism severity and its relationship to disability

The 10-year trajectory of aggressive behaviours in autistic individuals

BACKGROUND

Aggressive behaviours are common in people with neurodevelopmental conditions, contributing to poorer quality of life and placement breakdown. However, there is limited empirical research documenting the prevalence and persistence of aggressive behaviours in autism. In this longitudinal study, aggressive behaviours were investigated in a sample of autistic individuals over 10 years.

METHODS

Caregivers of autistic individuals, both with and without intellectual disability, completed questionnaires relating to the presence of aggressive behaviours at T1 [N = 229, mean age in years 11.8, standard deviation (SD) 5.9], T2 (T1 + 3 years, N = 81, mean age in years 15.1, SD 5.9) and T3 (T1 + 10 years, N = 54, mean age in years 24.5, SD 8.1). Analyses examined the presence and persistence of aggressive behaviours and the predictive value of established correlates of aggression.

RESULTS

Aggressive behaviours were common at baseline (61.6%) but only persistent in 30% of the sample over 10 years. Higher composite scores of overactivity and impulsivity at T1 were significantly associated with the persistence of aggressive behaviours at T2 (P = 0.027) and T3 (P = 0.012) with medium effect size.

CONCLUSIONS

Aggressive behaviours are common in autism, but reduce with age. Behavioural correlates of attention deficit hyperactivity disorder (ADHD) predict the presence and persistence of aggressive behaviour and as such may be useful clinical indicators to direct proactive intervention resources to ameliorate aggressive behaviours.

Factors influencing the mental health of autistic children and teenagers: Parents' observations and experiences

LAY ABSTRACT

Autistic people are more likely to experience mental health difficulties compared to neurotypical people. It is very important that we understand what increases the risk for mental health difficulties, and what helps to protect against them. So far, research on this for children and young people has only investigated a small number of factors and these have been chosen by researchers and clinicians. This study took a different approach in which parents' expertise in their children was recognised. Parents were asked to tell the story of their autistic teenagers' mental health from diagnosis in early childhood through to the present, and to explain the 'theories' they developed about what affected their child's mental health - positively and negatively - and how. Parents believed a wide range of factors played a role. These include: (1) aspects of their child (e.g. their autistic traits, intelligence); (2) aspects of their surroundings (e.g. the efforts parents make to prevent and respond to their child's difficulties, features of the school they attend, availability of social activities); (3) changes their child experienced growing up (e.g. puberty, awareness of being autistic); and (4) life events involving loss and separation. Many of the factors parents identified as important have received little or no research attention to date. The findings suggest issues that should be considered in future research and reveal ways that support for parents and autistic children and teenagers can be improved.

A cross-sectional examination of service complexity in youths with co-occurring autism spectrum disorder and psychiatric or medical diagnoses across service sectors

Introduction

Autism spectrum disorder (ASD) is a heterogeneous, life-long, and complex condition. Youth diagnosed with ASD require several supports addressing core symptoms associated with the disorder, but also those resulting from co-occurring mental and physical health conditions. As a result, their care is overseen by numerous professionals spanning various service sectors, but communication between sectors is hindered due to the absence of a standardized assessment system to identify and triage youth to services. A paucity of information surrounding this population's service use lingers and a siloed delivery system persists.

Methods

Using archival data collected from 1,020 youth between 12 and 18 years of age, this study explored service complexity among autistic youth with and without psychiatric and medical co-occurring conditions in Ontario, Canada. In doing so, a negative binomial regression was utilized to investigate which predisposing, enabling, and need variables were associated with service complexity.

Results

Results revealed that experiencing financial difficulties was not associated with service complexity. However, age, sex, caregiver distress, comorbidity, intellectual disability, and evaluated health status were significant predictors. More specifically, female youth and youth with distressed caregivers had greater mental health service complexity scores. Additionally, youth diagnosed with two or more conditions in addition to ASD who required longer durations of programming, controlling for other predictors, had greater mental health service complexity scores. Yet, youth with an intellectual disability had lower service complexity scores.

Discussion

Clinical implications of this study are discussed to inform future investments into mental health efforts for autistic youth.

Does the severity of autism symptoms change over time? A review of the evidence, impacts, and gaps in current knowledge

Studies evaluating change in autism symptom severity across the lifespan have yielded inconsistent results, making it difficult to assess the prevalence of meaningful change in autism symptom severity, and what characterizes it. Better understanding the ways in which autism symptoms change over time is crucial, with important implications for intervention. Synthesizing information across past studies, autism symptom severity change (especially decreases) appears common, though stability of symptoms is also frequent. Symptom severity change is characterized by variability in patterns of change between different individuals (between-person), variability in change within a person's trajectory across time (within-person), and variability in change patterns across symptom domains (i.e., social-communication, restricted/repetitive behaviors). Variability in severity change is likely impacted by differences in person-level characteristics (e.g., sex, IQ, sociodemographic factors) as well as developmental processes across time. Numerous methodological issues may impact our ability to understand how common change in symptom severity is, including varying measurement tools, analytic approaches, and change patterns between symptom domains across time. Potential implications of better understanding and characterizing symptom severity change include incorporation of severity change patterns and predictors of change into research on biomarkers, and consideration of such predictors as moderators or mediators of change in clinical practice.

Teacher- and parent-reported trajectories of maladaptive behaviors among individuals with autism and non-spectrum delays

People with autism spectrum disorder (ASD) and non-spectrum developmental delays frequently exhibit maladaptive behaviors throughout the lifespan, which can have pervasive effects on quality of life. Maladaptive behaviors have been shown to change over time as a function of various individual-level factors (e.g., cognitive ability), yet research is primarily limited to parent-reported measures. To expand upon this work, the present study aimed to examine trajectories of teacher- and parent-reported maladaptive behaviors (i.e., hyperactivity, irritability, social withdrawal) and to test whether individual-level predictors (e.g., autism features, verbal intelligence quotient) and school-related predictors (e.g., teacher type, student-adult ratio, personal aide, school type) impact these trajectories among 165 individuals with ASD or non-spectrum delays from ages 9 to 18. Multilevel models revealed that, according to both teacher and parent report, participants showed the greatest improvement in hyperactivity, less but still notable improvement in irritability, and stable levels of social withdrawal over time. Higher verbal ability and fewer ASD features, in addition to mainstream school placement, emerged as important individual- and school-related differences associated with fewer maladaptive behaviors over time. The multi-informant perspective and longitudinal design provide novel insight into the manifestations of these maladaptive behaviors across different contexts and across time. Findings highlight the consistency of teacher- and parent-reported trajectories over time and further emphasize the importance of targeting maladaptive behaviors using a multisystem intervention approach in both school and home contexts.

Brain white matter microstructure abnormalities in children with optimal outcome from autism: a four-year follow-up study

Autism spectrum disorder (ASD) is a lifelong neurodevelopmental disorder, with only a small proportion of people obtaining optimal outcomes. We do not know if children with ASD exhibit abnormalities in the white matter (WM) microstructure or if this pattern would predict ASD prognosis in a longitudinal study. 182 children with ASD were recruited for MRI and clinical assessment; 111 completed a four-year follow-up visit (30 with optimal outcomes, ASD-; 81 with persistent diagnosis, ASD+). Additionally, 72 typically developing controls (TDC) were recruited. The microstructural integrity of WM fiber tracts was revealed using tract-based spatial statistics (TBSS) and probabilistic tractography analyses. We examined the neuroimaging abnormality associated with ASD and its relationship to ASD with optimal outcome. The ASD+ and TDC groups were propensity score matched to the ASD- group in terms of age, gender, and IQ. TBSS indicated that children with ASD exhibited abnormalities in the superior longitudinal fasciculus (SLF), inferior longitudinal fasciculus (ILF), and extending to the anterior thalamic radiation (ATR) and cingulum; whereas the ASD+ group showed more severe abnormalities than the ASD- group. Probabilistic tractography analysis revealed that ASD+ group exhibited lower Fractional Anisotropy (FA) of the left superior thalamic radiation (STR L) than ASD- group, and that FA value of the STR L was a significant predictor of optimal outcome (EX(B), 6.25; 95% CI 2.50-15.63; p < 0.001). Children with ASD showed significant variations in SLF_L and STR_L, and STR_L was a predictor of 'ASD with optimal outcome'. Our findings may aid in comprehension of the mechanisms of 'ASD with optimal outcome'.

A data driven machine learning approach to differentiate between autism spectrum disorder and attention-deficit/hyperactivity disorder based on the best-practice diagnostic instruments for autism

Autism spectrum disorder (ASD) and attention-deficit/hyperactivity disorder (ADHD) are two frequently co-occurring neurodevelopmental conditions that share certain symptomatology, including social difficulties. This presents practitioners with challenging (differential) diagnostic considerations, particularly in clinically more complex cases with co-occurring ASD and ADHD. Therefore, the primary aim of the current study was to apply a data-driven machine learning approach (support vector machine) to determine whether and which items from the best-practice clinical instruments for diagnosing ASD (ADOS, ADI-R) would best differentiate between four groups of individuals referred to specialized ASD clinics (i.e., ASD, ADHD, ASD + ADHD, ND = no diagnosis). We found that a subset of five features from both ADOS (clinical observation) and ADI-R (parental interview) reliably differentiated between ASD groups (ASD & ASD + ADHD) and non-ASD groups (ADHD & ND), and these features corresponded to the social-communication but also restrictive and repetitive behavior domains. In conclusion, the results of the current study support the idea that detecting ASD in individuals with suspected signs of the diagnosis, including those with co-occurring ADHD, is possible with considerably fewer items relative to the original ADOS/2 and ADI-R algorithms (i.e., 92% item reduction) while preserving relatively high diagnostic accuracy. Clinical implications and study limitations are discussed.

Sibling Influences on Trajectories of Maladaptive Behaviors in Autism

Siblings play an important role in the behavioral trajectories of individuals with autism spectrum disorder (ASD). While having siblings has been associated with positive outcomes in ASD, including stronger adaptive functioning, social and non-verbal communication, and theory of mind, little is known about the impact of siblings on more negative outcomes, such as maladaptive behaviors. To address this gap, the present longitudinal study tested sibling predictors of trajectories of maladaptive behaviors (e.g., teacher- and parent-reported hyperactivity, irritability, and social withdrawal) from childhood through early adulthood among individuals with ASD and non-spectrum delays. Multilevel models revealed that, while the mere presence of a sibling did not impact maladaptive behavior trajectories apart from teacher-reported hyperactivity, the diagnostic profile of the sibling (e.g., emotional/behavioral disorder, ASD, medical condition) emerged as an important predictor. Specifically, although findings varied across teacher and parent reports, more hyperactivity and irritability across time was identified when the sibling had diagnoses of an emotional/behavioral disorder, ASD, and/or a medical condition. Overall, this study provides novel insight into the broader family-level factors that influence the presentation of maladaptive behaviors across time and across contexts.

Diagnostic stability in individuals with autism spectrum disorder: insights from a longitudinal follow-up study

BACKGROUND

This longitudinal study of autism symptom trajectories provides unique information that can characterize autism features and diagnostic patterns from childhood to adulthood.

METHODS

Participants (n = 155) were part of a longitudinal cohort referred for possible autism where in-person assessments were completed at ages 2, 3, 5, 9, 19, and 25. Assessors were blinded to previous diagnoses. Based on adult best estimate diagnoses, participants were categorized into one of the four groups: Retained ASD, Lost ASD, Never Had ASD, or Gained ASD Diagnosis. To examine developmental changes in autism symptoms, mixed models indicated the rate of change in ADOS CSS and ADI-R scores in each diagnostic group.

RESULTS

A subset of participants with VIQ> and <70 were assigned a diagnosis in adulthood that differed from diagnoses earlier in development. Across cognitive levels, the majority of novel diagnoses emerged in adulthood. For those with VIQ > 70, improvements in ADOS CSS over time for the Lost Diagnosis group and worsening in CSS in the Gained Diagnosis group were gradual. Individuals with VIQ > 70 who lost a diagnosis even in adulthood could be distinguished on CSS and ADI-R scores by age 5 from those who retained their ASD diagnosis. Although most participants with VIQ < 70 saw decreases in autistic symptoms as a whole, changes in autism diagnoses were confounded by disentangling profound intellectual disability as a differential diagnosis or co-occurrence. Only the Never Had Diagnosis group revealed significant changes in ADOS scores over time, with autism symptoms increasing.

CONCLUSIONS

Associated with gradual changes in core features of autism beginning in childhood, diagnoses of autism can shift across development.

Verbal Ability, Behavior Problems, and Mother-Child Relationship Quality in Autism Spectrum Disorder

This study examined differences in mother-child relationship quality and parent-rated child behavior problems based on child verbal status (i.e., minimally verbal versus verbal) in mothers and their adolescent and adult children with autism spectrum disorder (n = 219 dyads; child M_age = 25.38 years, SD = 10.22). Relationship quality was assessed via parent-reported maternal burden and mother-child closeness, and coded speech samples ascertaining maternal critical and positive remarks regarding the child. Groups did not differ in relationship quality. The verbal group was more likely to display disruptive and socially inappropriate behaviors, but otherwise the groups did not differ in behavior problems. Verbal status moderated the relationship between behavior problems and negative (maternal burden, critical remarks) but not positive (mother-child closeness, positive remarks) aspects of relationship quality.

Change in Maladaptive Behavior Affects Intergenerational Relationships in Fragile X Syndrome

This study investigated the bidirectional effects of change in maladaptive behaviors among adolescents and adults with fragile X syndrome (FXS) and change in their intergenerational family relationships over a 7.5-year period. Indicators of the intergenerational family relationship between premutation carrier mothers and their adolescent or adult son/daughter with FXS included a measure of the quality of the relationship, as well as descriptions provided by mothers of their relationship with their son/daughter (positive remarks, critical remarks). Maladaptive behaviors decreased, maternal positive remarks increased, and maternal critical remarks and relationship quality remained stable over time. Bidirectional effects of change were observed in predicting maladaptive behaviors and maternal positive remarks, although maladaptive behaviors more strongly predicted positive remarks than the reciprocal association. This research suggests prioritizing maladaptive behaviors in the context of family interventions.

Parental self-efficacy and family quality of life in parents of children with autism spectrum disorder in China: The possible mediating role of social support

OBJECTIVE

This study explored the related factors of FQOL in parents of children with ASD and examined whether social support mediates the relationship between parental self-efficacy and FQOL in parents of children with ASD.

DESIGN AND METHODS

Using a cross-sectional design, a total of 260 parents of children with ASD were recruited from September 2019 to November 2020. They completed the Beach Center Family Quality of Life Scale, the Parenting Sense of Competence Scale, and the Social Support Rating Scale.

RESULTS

Parental self-efficacy and social support explained approximately 49.5% of the variance in FQOL. After controlling for the confounding influence of parents' education level, parental self-efficacy had a direct effect on FQOL (β = 0.292, SE = 0.108, P < 0.01) and an indirect effect on FQOL (β = 0.165, SE = 0.069, P < 0.01). Effects were mediated through social support, with partial mediating effects accounting for 36.11% of the total effect.

CONCLUSIONS

Both parental self-efficacy and social support are critical to promoting FQOL, and a partial mediating effect of social support was established.

PRACTICAL IMPLICATIONS

Interventions for families with children with ASD should focus on enhancing parental self-efficacy, followed by a perceived social support and FQOL prompt.

Characterizing Parent–Child Interactions in Families of Autistic Children in Late Childhood

Parent–child interactions are influential to a wide range of positive developmental processes in neurotypical children, yet contributions to our understanding of these interactions using observational methods in families of children on the autism spectrum are lacking. The aim of the current study is to investigate how autism symptoms might impact these interactions. We use a family discussion task to: (1) compare families of autistic children aged 8–12 years (n = 21) to families of typically developing children (n = 21, matched on age and cognitive abilities) on the observed levels of supportive and directive behaviors in the parent–child relationship, and (2) examine the associations between parent–child interaction characteristics and child functioning. Results showed no differences in the observed levels of supportive behavior exhibited by parents, but significantly less supportive behavior in autistic children compared to neurotypical children. In addition, parents of autistic children had higher levels of observed directive behavior compared to parents of neurotypical children. Levels of supportive behavior in parents and autistic children were negatively associated with child ADHD symptoms. Findings reinforce literature on younger children describing positive parenting characteristics and further rebuke historical accounts of negative parenting qualities of parents of autistic children.

Adults with Autism: Changes in Understanding Since DSM-111

Over the past four decades there have been significant advances in our understanding of autism, yet services for autistic adults continue to lag far behind those for children, and prospects for employment and independent living remain poor. Adult outcomes also vary widely and while cognitive and language abilities are important prognostic indicators, the influence of social, emotional, familial and many other factors remains uncertain. For this special issue marking the 40th anniversary of DSM-III, the present paper describes the changing perspectives of autism in adulthood that have occurred over this period, explores individual and wider environmental factors related to outcome, and suggests ways in which services need to be changed to improve the future for adults living with autism.

Gender Differences in Peer Influence on Autistic Traits in Special Needs Schools-Evidence From Staff Reports

Children and adolescents with an intellectual disability (ID) and autistic traits often attend special needs schools where they are surrounded by peers with diverse characteristics. Given the role that peers can play in social development, we examined whether autistic traits development in students with ID and high levels of such characteristics are influenced by the level of autistic traits among the schoolmates they like most. Furthermore, we investigated the degree to which this peer influence susceptibility depends on students’ gender. A longitudinal design, with data collection points at the beginning and the end of a school year, was used. Staff reported on 330 students with high levels of autistic traits (20.6% girls; age 10.17 years, SD = 3.74) who attended 142 classrooms in 16 Swiss special needs schools. Results showed that students’ future individual level of autistic traits (T2) was not predicted by the autistic traits level of preferred peers (T1), controlling for individual autistic traits at T1, level of general functioning, gender, and age. However, the peer effect was significantly moderated by students’ gender, indicating that girls but not boys were susceptible to peer influence. These findings are discussed in terms of implications for understanding autistic traits development and directions of support for children and adolescents in their peer context.

Impact of Working Together for adults with autism spectrum disorder: a multifamily group intervention

BACKGROUND

Adults with autism spectrum disorder (ASD) have lower engagement in their communities, higher rates of unemployment/underemployment, and continued difficulties with challenging behavior compared to their neurotypical peers. Multi-family psychoeducation emphasizes education and problem-solving with the goal of improving these outcomes for the individual with the disability.

METHODS

Using a randomized waitlist control design, the present study evaluated a multi-family group psychoeducation intervention, Working Together, for adults on the autism spectrum without intellectual disability (n = 40). Five waves of data were collected at 3-month intervals. In this design, families in the intervention condition participated in intervention during the 6 months between baseline and time 3 data collection; the waitlist control condition received the intervention immediately after the time 3 data collection. We compared these two conditions, intervention group (n = 20) vs waitlist control group (n = 20), on key outcomes for the adults with ASD: engagement in work-related activities, engagement in meaningful activities, and behavior problems.

RESULTS

Results indicated medium to large effect sizes associated with the Working Together intervention across key outcomes, including adults on the spectrum experiencing significant increases in meaningful activities and decreases in internalizing problems. Although increases in work-related activities were not statistically significant, an observed one-half of a standard deviation difference from before to after the intervention indicated clinically significant change. We also found maintenance of the treatment effect through 6 months post-treatment for the intervention group and replication of the treatment effect within the control group after they received the intervention.

CONCLUSION

Working Together is a promising multi-family group psychoeducation intervention designed to improve functioning during adulthood. These findings highlight the need for more intervention services research during adulthood and specifically the need for family-centered supports.

Is the Combination of ADOS and ADI-R Necessary to Classify ASD? Rethinking the "Gold Standard" in Diagnosing ASD

Diagnosing autism spectrum disorder (ASD) requires extensive clinical expertise and training as well as a focus on differential diagnoses. The diagnostic process is particularly complex given symptom overlap with other mental disorders and high rates of co-occurring physical and mental health concerns. The aim of this study was to conduct a data-driven selection of the most relevant diagnostic information collected from a behavior observation and an anamnestic interview in two clinical samples of children/younger adolescents and adolescents/adults with suspected ASD. Via random forests, the present study discovered patterns of symptoms in the diagnostic data of 2310 participants (46% ASD, 54% non-ASD, age range 4-72 years) using data from the combined Autism Diagnostic Observation Schedule (ADOS) and Autism Diagnostic Interview-Revised (ADI-R) and ADOS data alone. Classifiers built on reduced subsets of diagnostic features yield satisfactory sensitivity and specificity values. For adolescents/adults specificity values were lower compared to those for children/younger adolescents. The models including ADOS and ADI-R data were mainly built on ADOS items and in the adolescent/adult sample the classifier including only ADOS items performed even better than the classifier including information from both instruments. Results suggest that reduced subsets of ADOS and ADI-R items may suffice to effectively differentiate ASD from other mental disorders. The imbalance of ADOS and ADI-R items included in the models leads to the assumption that, particularly in adolescents and adults, the ADI-R may play a lesser role than current behavior observations.

Verbal Ability, Behavior Problems, and Mother-Child Relationship Quality in Autism Spectrum Disorder

This study examined differences in mother-child relationship quality and parent-rated child behavior problems based on child verbal status (i.e., minimally verbal versus verbal) in mothers and their adolescent and adult children with autism spectrum disorder (n = 219 dyads; child M_age = 25.38 years, SD = 10.22). Relationship quality was assessed via parent-reported maternal burden and mother-child closeness, and coded speech samples ascertaining maternal critical and positive remarks regarding the child. Groups did not differ in relationship quality. The verbal group was more likely to display disruptive and socially inappropriate behaviors, but otherwise the groups did not differ in behavior problems. Verbal status moderated the relationship between behavior problems and negative (maternal burden, critical remarks) but not positive (mother-child closeness, positive remarks) aspects of relationship quality.

Expressed Emotion in Families of Children With and Without Autism Spectrum Disorder, Cerebral Palsy and Down Syndrome: Relations with Parenting Stress and Parenting Behaviors

This study examined the family emotional climate as assessed by Five Minute Speech Samples and the relation with parenting stress and parenting behaviors among parents of children (6-17 years, 64.7% boys) with autism spectrum disorder, cerebral palsy, Down syndrome, and without any known disability (n = 447). The large majority of parents (79%) showed low levels of Expressed Emotion, an indicator of a positive family climate. In all groups, more Emotional Over-involvement, more Criticism and fewer expressions of Warmth were associated with higher levels of parenting stress. Across groups, Emotional Over-involvement was related to more autonomy-supportive parenting, Criticism to more psychologically controlling and overreactive parenting, and Warmth was associated with more responsive and less psychologically controlling and overreactive parenting.

"I Met Someone Like Me!": Autistic Adolescents and Their Parents' Experience of the KONTAKT® Social Skills Group Training

This study captured the experiences of 35 autistic adolescents and their parents after completing a 16-session variant of social skills group training KONTAKT® (ACTRN12617001117303). Semi-structured interviews explored participants' and relatives' perceptions of KONTAKT® and associated social outcomes. Adolescents were classified as either high (HR, n = 23) or low (LR, n = 12) responders based on the primary outcome effects during the previous trial. Thematic analysis revealed that both HR and LR participants their parents were satisfied with KONTAKT®, noting consistent patterns of improvement in adolescents' social understanding, communication, relationships, and empowerment, although positive reports were more frequent among HR than LR groups. This study enhances the understanding of the impact of SSGT, which is key in improving their content, principles, and administration.

The Role of the Family's Emotional Climate in the Links between Parent-Adolescent Communication and Adolescent Psychosocial Functioning

The current study was designed to extend the parenting literature by testing the moderating role of the family's emotional climate, operationalized with parent-adolescent emotional closeness and adolescent feelings of being overly controlled by parents on the longitudinal associations between parent-driven communication efforts (i.e. parental behavioral control and solicitation of information from their adolescent), adolescent-driven communication efforts (i.e. adolescent disclosure and secrecy) and adolescent psychosocial functioning (i.e. emotional problems, conduct problems, delinquency, and wellbeing). We conducted a series of cross-lagged models controlling for adolescent gender and ethnicity using a two-wave Swedish longitudinal set of self-report data (N = 1515, 51% girls, M age = 13.0 and 14.3 years at T1 and T2, respectively). Multi-group analyses revealed that the negative links between T1 parental control and T2 adolescent delinquency, T1 parental solicitation and T2 adolescent conduct problems and delinquency, and T1 emotional problems and T2 adolescent disclosure were moderated by the family's emotional climate. When the family's emotional climate was positive, the parenting strategies had a more positive effect on adolescent psychosocial functioning, and adolescents with emotional problems communicated more openly with their parents. These findings suggest that the relational context in the family is an important protective factor and add specificity to the previously established role of parent-adolescent communication in adolescent psychosocial development. In terms of preventive interventions, strategies to enhance the family's emotional climate should be considered prior to teaching specific parenting strategies.

Predictors of Treatment Outcome in Preschoolers with Autism Spectrum Disorder: An Observational Study in the Greater Geneva Area, Switzerland

This study aims to identify predictors of treatment outcome in young children with ASD within a European context, where service provision of intervention remains sporadic. We investigated whether a child's age at baseline, intensity of the intervention provided, type of intervention, child's level of social orienting and cognitive skills at baseline predicted changes in autistic symptoms and cognitive development after 1 year of intervention, in a sample of 60 children with ASD. Our results strongly support early and intensive intervention. We also observed that lower cognitive skills at baseline were related to greater cognitive gains. Finally, we show that a child's interest in social stimuli may contribute to intervention outcome.

Trajectories in Symptoms of Autism and Cognitive Ability in Autism From Childhood to Adult Life: Findings From a Longitudinal Epidemiological Cohort

OBJECTIVE

For the first time, we use a longitudinal population-based autism cohort to chart the trajectories of cognition and autism symptoms from childhood to early adulthood and identify features that predict the level of function and change with development.

METHOD

Latent growth curve models were fitted to data from the Special Needs and Autism Project cohort at three time points: 12, 16, and 23 years. Outcome measures were IQ and parent-reported Social Responsiveness Scale autism symptoms. Of the 158 participants with an autism spectrum disorder at 12 years, 126 (80%) were reassessed at 23 years. Child, family, and contextual characteristics obtained at 12 years predicted intercept and slope of the trajectories.

RESULTS

Both trajectories showed considerable variability. IQ increased significantly by a mean of 7.48 points from 12 to 23 years, whereas autism symptoms remained unchanged. In multivariate analysis, full-scale IQ was predicted by initial language level and school type (mainstream/specialist). Participants with a history of early language regression showed significantly greater IQ gains. Autism symptoms were predicted by Social Communication Questionnaire scores (lifetime version) and emotional and behavioral problems. Participants attending mainstream schools showed significantly fewer autism disorder symptoms at 23 years than those in specialist settings; this finding was robust to propensity score analysis for confounding.

CONCLUSION

Our findings suggest continued cognitive increments for many people with autism across the adolescent period, but a lack of improvement in autism symptoms. Our finding of school influences on autism symptoms requires replication in other cohorts and settings before drawing any implications for mechanisms or policy.

The Prevalence of Self-injurious Behaviour in Autism: A Meta-analytic Study

Self-injurious behaviour is purportedly common in autism, but prevalence rates have not yet been synthesised meta-analytically. In the present study, data from 14,379 participants in thirty-seven papers were analysed to generate a pooled prevalence estimate of self-injury in autism of 42% (confidence intervals 0.38-0.47). Hand-hitting topography was the most common form of self-injury (23%), self-cutting topography the least common (3%). Sub-group analyses revealed no association between study quality, participant intellectual disability or age and overall prevalence rate of self-injury. However, females obtained higher prevalence rates than males (p = .013) and hair pulling and self-scratching were associated with intellectual disability (p = .008 and p = .002, respectively). The results confirm very high rates of self-injury in autism and highlight within group risk-markers.

Negative Controlling Parenting and Child Personality as Modifiers of Psychosocial Development in Youth with Autism Spectrum Disorder: A 9-Year Longitudinal Study at the Level of Within-Person Change

This nine-year longitudinal study addresses the joint contribution of parent-rated negative controlling parenting and child personality on psychosocial outcomes in 141 families of children with autism spectrum disorder (83% boys, mean age Time 1 = 10.1). Latent change modeling revealed substantial variation in within-person change in parenting and psychosocial outcomes across a six- and three-year-interval. Over time, negative controlling parenting and child personality were consistently related to externalizing problems, whereas child personality was differentially related to internalizing problems and psychosocial strengths. Three personality-by-parenting interactions were significant, suggesting that children with less mature personality traits show more externalizing behaviors in the presence of controlling parenting. This study identified both parenting and child personality as important modifiers of developmental outcomes in youth with autism.

Improving the Validity and Generalizability of Adult Autism Research Through Incorporating Family and Cultural Contexts

The relatively nascent empirical knowledge base regarding autism in adulthood provides an opportunity to adopt a contextual approach that conceptualizes autism features, outcomes, and supportive services as interactions between the characteristics of the condition and contextual factors across the life course. Although a contextual approach encompasses many aspects of a person's identity and social ecology, we focus here on the closely interrelated family and cultural contexts, which have been poorly integrated into adult autism research. We argue that designing studies with a priori attention to context (e.g., family and culture) will improve the relevance and comprehensiveness of findings, which in turn will improve construct validity and provide a more accurate understanding of autism-related outcomes in adulthood. Similarly, designing and/or selecting measures that have been validated with culturally and linguistically diverse samples will improve the utility of findings and reduce spurious or null effects. More contextually informed methodologies will lead to improved generalizability and practical applications of findings. We offer concrete guidance regarding how to increase the social ecological perspective within adult autism research as it relates to study conceptualization, methodology, and measurement.

Student, Educator, and Parent Perspectives of Self-Determination in High School Students with Autism Spectrum Disorder

Self-determination refers to an individual being a causal agent in their daily activities, including the ability to express their own needs, interests, and wants, make choices, and set goals. Self-determination is critical during adolescence and has been linked to positive educational outcomes in individuals with disabilities. Few studies have characterized the measurement of self-determination in adolescents with autism spectrum disorder (ASD). The purpose of the current study was to (a) examine the agreement across the American Institutes for Research Self-Determination Scale (Wolman et al., AIR Self-determination scale and user guide. Palo Alto, CA: American Institute for Research, 1994) student, educator, and parent forms for high school students with ASD, and (b) examine student and family predictors of self-determination. Participants included adolescents with ASD (N = 547, mean chronological age = 16.1 years, SD = 1.4 years), their parents, and educators. Student reports did not correspond to parent or educator reports, and parent and educator reports were in moderate agreement. Adaptive behavior was a significant predictor of self-determination across reporters, highlighting the significance of adaptive behavior skills during high school. In addition to promoting adaptive behavior, supporting family empowerment, and reducing family burden may help to increase self-determination in high school students with ASD. LAY SUMMARY: Self-determination refers to the abilities and opportunities for students to make choices, plans, and set goals. The current study examined self-determination from multiple perspectives in a large, diverse sample of high school students with ASD. Students, parents, and their teachers each completed a questionnaire on self-determination and had little to some agreement across reporters. Providing support to families and help for students to increase independent skills may promote self-determination.

Trajectories of Change in the Behavioral and Health Phenotype of Adolescents and Adults with Fragile X Syndrome and Intellectual Disability: Longitudinal Trends Over a Decade

This study examined trajectories of daily living skills, behavior problems, body mass index (BMI), and health conditions spanning nearly a decade in adolescents and adults with fragile X syndrome (N = 134; age range at study end = 19-49 years), examining influences of sex and autism spectrum disorder (ASD) symptoms. Hierarchical linear modeling revealed early increases in daily living skills, with decreases at older ages. Behavior problems became less severe over time, with some increases at older ages. Individuals gained weight and had increasing health problems over time. Fewer ASD symptoms were associated with greater daily living skills and fewer behavior problems at study start. This study offers some of the first prospective quantitative analyses of behavioral and health life course trajectories in FXS.

Trajectories of emotional and behavioral problems from childhood to early adult life

LAY ABSTRACT

Although mental health problems are common in autism, relatively little is known about their stability and the factors that influence their persistence or change over the life-course. To address this, we use data from the Special Needs and Autism Project (SNAP) cohort studied at three time-points from 12 to 23 years. Using the parent-reported Strengths and Difficulties Questionnaire (SDQ) domains of conduct, emotional, and ADHD symptoms, we evaluated the role of child, family, and contextual characteristics on these three trajectories. Symptoms decreased significantly over time for all three domains, but many participants still scored above the published disorder cutoffs. Individuals showed high levels of persistence. Higher initial adaptive function and language levels predicted a greater decline in conduct and ADHD symptoms. In contrast, higher language functioning was associated with higher levels of emotional symptoms, as was lower levels of autism symptom severity and higher parental education. Those with higher neighborhood deprivation had higher initial conduct problems but a steeper decline over time. Our findings highlight that it may be possible to accurately predict mental health trajectories over this time period, which could help parents and carers in planning and help professionals target resources more efficiently.

Social cognition in adults with autism spectrum disorders: Validation of the Edinburgh Social Cognition Test (ESCoT)

OBJECTIVE

Many existing tests of social cognition are not appropriate for clinical use, due to their length, complexity or uncertainty in what they are assessing. The Edinburgh Social Cognition Test (ESCoT) is a new test of social cognition that assesses affective and cognitive Theory of Mind as well as inter- and intrapersonal understanding of social norms using animated interactions.

METHOD

To support the development of the ESCoT as a clinical tool, we derived cut-off scores from a neurotypical population (n = 236) and sought to validate the ESCoT in a sample of Autism Spectrum Disorder (ASD; n = 19) adults and neurotypical controls (NC; n = 38) matched on age and education. The ESCoT was administered alongside established tests and questionnaire measures of ASD, empathy, systemizing traits and intelligence.

RESULTS

Performance on the subtests of the ESCoT and ESCoT total scores correlated with performance on traditional tests, demonstrating convergent validity. ASD adults performed poorer on all measures of social cognition. Unlike the ESCoT, performance on the established tests was predicted by verbal comprehension abilities. Using a ROC curve analysis, we showed that the ESCoT was more effective than existing tests at differentiating ASD adults from NC. Furthermore, a total of 42.11% of ASD adults were impaired on the ESCoT compared to 0% of NC adults.

CONCLUSIONS

Overall these results demonstrate that the ESCoT is a useful test for clinical assessment and can aid in the detection of potential difficulties in ToM and social norm understanding.

Effects of parenting adults with disabilities on later-life health: The role of intergenerational ambivalence

According to family systems theory, strains from parenting an adult with disabilities may spill over to parents' relationships with their other children and disrupt family dynamics and their well-being in later-life. This study examined whether parental ambivalence toward their nondisabled children is greater in families of adults with disabilities (developmental disabilities [DD] or serious mental illnesses [SMI]) than families without any adult children with disabilities. The study also investigated whether ambivalence mediates the associations between having an adult child with DD or SMI and parents' health. Data were from the 2011 Wisconsin Longitudinal Study in which aging parents (M_age = 71; n = 6,084) were asked about their relationship with each of their adult children. Multilevel regression models and multilevel structural equation models were estimated to analyze the data. Our findings showed that parents of an adult with SMI felt greater ambivalence toward their nondisabled adult children than comparison group parents of adult children without disabilities, whereas no significant differences were found between parents of an adult child with DD and comparison group parents. Parental ambivalence toward their nondisabled adult children played a significant indirect role in the negative association between having a child with SMI and parental physical and mental health. The findings have implications for clinical practice with aging families of adults with disabilities and suggest the need for additional research to better understand intergenerational parent-adult child dynamics in these families.

1000 Families Study, a UK multiwave cohort investigating the well-being of families of children with intellectual disabilities: cohort profile

PURPOSE

The 1000 Families Study is a large, UK-based, cohort of families of children with intellectual disability (ID). The main use of the cohort data will be to describe and explore correlates of the well-being of families of children with ID, including parents and siblings, using cross-sectional and (eventually) longitudinal analyses. The present cohort profile intends to describe the achieved cohort.

PARTICIPANTS

Over 1000 families of UK children with ID aged between 4 and 15 years 11 months (total n=1184) have been recruited. The mean age of the cohort was 9.01 years old. The cohort includes more boys (61.8%) than girls (27.0%; missing 11.1%). Parents reported that 45.5% (n=539) of the children have autism. Most respondents were a female primary caregiver (84.9%), and 78.0% were the biological mother of the cohort child with ID. The largest ethnic group for primary caregivers was White British (78.5%), over half were married and living with their partner (53.3%) and 39.3% were educated to degree level.

FINDINGS TO DATE

Data were collected on family, parental and child well-being, as well as demographic information. Wave 1 data collection took place between November 2015 and January 2017, primarily through online questionnaires. Telephone interviews were also completed by 644 primary caregivers.

FUTURE PLANS

Wave 2 data collection is ongoing and the research team will continue following up these families in subsequent waves, subject to funding availability. Results will be used to inform policy and practice on family and child well-being in families of children with ID. As this cohort profile aims to describe the cohort, future publications will explore relevant research questions and report key findings related to family well-being.

Long-term outcome of autism spectrum disorder

In most cases, autism spectrum disorder is a life-long condition, often severely affecting the quality of life of the patient and his/her family, but nowadays this diagnosis should not be considered a final sentence without appeal. Although even today the recovery from the autism spectrum is an unlikely possibility, a timely psycho-educational intervention can significantly improve the level of autonomy reached by the individual and therefore favorably modify the outcome. Some predictors of long-term outcome are known, primarily childhood intelligence quotient and early language/communication ability, but today this issue is still open. The lack of studies evaluating the long-term effects of the most important intervention programmes should be filled with adequate research. Community support and social integration may be very important in improving outcomes for individuals with autism spectrum disorder. But a real social integration involves a work activity and this is still a great problem today. An adequate and timely preparation of the working career of these individuals is fundamental for their future, and it should be done by choosing, as far as possible, suitable activities for them. Finally, in creating a dignified future for people with autism, we must never forget to listen to their point of view, whenever possible, in order to meet their particular needs.

Attachment and child behaviour and emotional problems in autism spectrum disorder with intellectual disability

BACKGROUND

Behaviour and emotional problems are highly prevalent in children with autism spectrum disorder (ASD). In typically developing children, attachment quality acts as a risk/protective factor for behavioural outcomes and adjustment, warranting investigation in children with ASD.

METHOD

We investigated the relationship between attachment and child behaviour and emotional problems in children with ASD and comorbid intellectual disability. Data were collected from parent-child dyads where children were diagnosed with ASD and ID (n = 28) or other developmental disabilities (n = 20).

RESULTS

Children with ASD had higher levels of behaviour and emotional problems and more attachment difficulties than children with other developmental disabilities. Poorer attachment quality contributed uniquely to the variance in child behaviour and emotional problems.

CONCLUSIONS

Interventions targeting behaviour and emotional problems in children with ASD may benefit from an attachment model which addresses the child's difficulty in using caregivers as a coregulatory agent of emotions.

Emotion Control Predicts Internalizing and Externalizing Behavior Problems in Boys With and Without an Autism Spectrum Disorder

Children and adolescents with Autism Spectrum Disorder (ASD) often show comorbid emotional and behavior problems. The aim of this longitudinal study is to examine the relation between emotion control (i.e., negative emotionality, emotion awareness, and worry/rumination) and the development of internalizing and externalizing problems. Boys with and without ASD (N = 157; age 9–15) were followed over a period of 1.5 years (3 waves). We found that baseline levels of worry/rumination was a specific predictor of later externalizing problems for boys with ASD. Furthermore, the developmental trajectory of worry/rumination predicted the development of internalizing and externalizing problems in both groups. Our findings suggest that worry/rumination may constitute a transdiagnostic factor underlying both internalizing and externalizing problems in boys with and without ASD.

Autism aging

Many people perceive autism spectrum disorder (ASD) as a childhood disorder, yet ASD is a lifelong condition. Although little is known about the mental and physical health issues of aging individuals with ASD, there are increasing numbers of older adults being diagnosed with ASD. Although there has been a recent "call to action" (to address lack of knowledge and the dearth of services and programs for aging individuals with autism, the authors think it is also important for those who are involved in educational programs related to gerontology and geriatrics settings to be aware of "autism aging." This term conceptualizes the demographics, person and contextual factors, and intellectual awareness of the trends and patterns of ASD as a life course challenge and opportunity for well-being and quality of life. The purposes of this article are to (1) provide a general overview of autism issues and to examine several dimensions of ASD in the context of the emergent and relevant scholarship in the adult and aging domain, (2) propose how to address the "gap" in the literature on autism and aging in terms of a conceptual model and by improving the methodology, and (3) to discuss the implications of these dimensions for educators in gerontology and geriatrics, and for those professionals who work in clinical and health care services. It is the goal of the authors to have this article represent a general introduction to ASD and to be a part of the foundation for educational awareness for educators in gerontology and geriatrics.

Childhood autism in the UK and Greece: a cross-national study of progress in different intervention contexts

Aim: This is a cross-national study with the aim to explore the development of children with autism over time in the UK and Greece. The focus of the study was to investigate the differences in language and social skills between children with autism across the two countries who were receiving different types of treatment: speech and language therapy, psychoanalytic/psychodynamic psychotherapy, and occupational therapy. Study design: A cross-national longitudinal design with a mixed (between-subjects and within-subjects) design. Participants: A sample of 40 children in total. In the UK, 20 children with autism who had received psychotherapy (n = 10) and speech and language therapy (n = 10) were recruited and monitored post-therapy twice over a two-year period. In Greece, 20 children with autism who received occupational therapy (n = 10) and speech and language therapy (n = 10) were recruited and monitored post-therapy twice over a two-year period. Results: All children changed significantly over time on all aspects of measurement, demonstrating that children with autism are developing in a very similar way across the two countries. With respect to the effect of the therapy context on the development of children with autism, it was found that there were no differences across intervention contexts at the start of the study, and there were mainly nonsignificant interactions in the rate of change across the differing types of intervention. However, further analysis showed some important differences: speech and language therapy participants presented more widespread change on language scores across the measures; psychotherapy participants showed significant greater increase in imagination and decrease in stereotypical behavior; and occupational therapy participants presented significant reduction of stereotypical behavior. Conclusions: This study can help professionals who work with children with autism further their understanding of the disorder and how it manifests through time in order to provide appropriate services based on each child's needs. Keywords: Childhood autism, speech and language therapy, psychotherapy, occupational therapy, UK, Greece.

Interventions Targeting Expressive Communication in Adults With Autism Spectrum Disorders: A Systematic Review

Purpose The aims of this systematic review are to (a) synthesize the literature on interventions targeting expressive communication in adults with autism spectrum disorder and (b) evaluate the effectiveness of the interventions. Method The literature search resulted in 7,196 articles. The research team used 2 reviewers and consensus for title/abstract review, full-text review, and quality review. To be included, studies had to (a) include at least 1 adult (18 years of age and above) with an autism spectrum disorder; (b) examine an intervention, treatment, or model of care; (c) provide outcome data related to expressive communication modalities/domains; (d) be experimental or quasi-experimental; and (e) be published in English. Twenty-two studies (14 single-case design and 8 group design), with a total of 256 participants and varied interventions and outcome variables, met criteria for inclusion. Effect sizes are presented for group design studies, and visual analysis results are outlined for single-case design studies. Results Examination of treatment effects in the included studies showed positive effects, overall; however, there was great variability between studies. Single-case design studies showed evidence of functional relations in all but 1 study, with most showing medium to large effects, as well as maintenance and generalization of gains. Group design studies showed a wide range of effects from near-zero to large effects. Differences in intervention strategies and durations, as well as in participant characteristics and outcome measures, presented barriers to aggregation. Conclusions This review highlights the need for increased high-quality research examining interventions targeting expressive communication in adults with autism spectrum disorder and also pinpoints interventions with potential for future study and use in this population.
