Complementing or Congruent? Desired Characteristics in a Friend and Romantic Partner in Autistic versus Typically Developing Male Adolescents.

Ideal friend and romantic partner characteristics related to self-perceived characteristics have been investigated in typically developing (TD) individuals, but not in individuals with autism spectrum disorder (ASD). Considering the autistic symptoms and challenges, investigating these concepts in autistic individuals is relevant. Given the lack of consensus, identity-first ("autistic person") and person-first ("person with autism") language are mixed throughout, to cover all preferences. This study explored (1) the association between self-perceived characteristics and desires in a friend/romantic partner, as well as (2) compare two groups (ASD and TD) in their desires for a friend/romantic partner. Two matched groups (ASD and TD) of 38 male adolescents (age 14-19 years) reported on the desire for nine characteristics (i.e., funny, popular, nice, cool, smart, trustworthy, good looking, similar interests, and being rich) in a friend/partner, and to what extent they felt they themselves possessed seven characteristics (i.e., funny, popular, nice, cool, smart, trustworthy, and good looking). Results showed both groups sought a friend and partner similar to themselves on intrinsic characteristics (e.g., trustworthiness), but less similar on extrinsic and social status characteristics (e.g., being less cool and popular). Particularly intrinsic characteristics, more than extrinsic and social status characteristics, were valued in both partners and friends, regardless of group. No significant differences were found between groups concerning to what extent characteristics were desired. Overall, adolescents with ASD desire similar characteristics as TD adolescents in their potential romantic partners and friends. There is some indication that the match between self-perception and desired characteristics is different.

See the self through others' eyes: The development of moral emotions in young children with autism spectrum disorder.

Despite the important social functions of moral emotions, they are understudied in the autism spectrum disorder (ASD) population. This three-wave longitudinal study is among the first to examine the development of moral emotions and their associations with theory of mind in 3- to 7-year-old children with ASD, using observational tasks. One hundred and forty-two children (52 with ASD) were followed over a period of 2 years. We found that while the expressions of shame and guilt remained stable in non-ASD children, they decreased with age in children with ASD. No group differences were found in the levels or the developmental trajectories of pride. Besides, better false-belief understanding was uniquely related to the expressions of pride in children with ASD. Our findings highlight the importance of enhancing understanding of moral emotion development and related factors in children with ASD.

A randomized controlled trial to examine the effectiveness of the Dutch version of the Program for the Education and Enrichment of Relational Skills (PEERS®).

BACKGROUND: This study examines the effectiveness of the culturally adapted Dutch version of The Program for the Education and Enrichment of Relational Skills (PEERS®), utilizing a randomized control trial (RCT) with an active treatment control condition. METHODS: 106 adolescents with ASD, aged 12-18 years, were randomly assigned to one of two group interventions: the experimental condition (PEERS®; n = 54) or the active treatment control condition (Regulation, Organization and Autonomy Didactics; ROAD; n = 52). Effects of interventions on social skills were primarily assessed using an observational measure (CASS - Contextual Assessment Social Skills). Secondary indices of social skills were self, parent and teacher reported questionnaire data (i.e., Social Responsiveness Scale; SRS, and Social Skills Improvement System; SSIS). Treatment satisfaction was also obtained from adolescents and their parents. RESULTS: Results on the observational measure of social skills revealed improvements in positive affect, overall quality of rapport, as well as starting and ending a conversation, irrespective of condition. Compared to ROAD, PEERS® participants showed increased overall self-reported social skills (SSIS). Parent reports showed decreased overall social skill impairment (SRS) as well as improved social communication (SSIS subscale), with significantly more progress in the PEERS® group. Furthermore, parents of adolescents in the PEERS® group were significantly more satisfied with the intervention (M = 8.20, SD = 1.46) than parents of adolescents in the ROAD group (M = 7.52, SD = 1.45). The self-reported treatment satisfaction of adolescents did not differ between conditions. Teacher data showed decreased social skill impairment as measured with the SRS, irrespective of condition. CONCLUSIONS: This study reveals promising indications that the Dutch version of PEERS® enhances social skills in adolescents with ASD. Yet, further research is needed into how effectiveness can be optimized. TRIAL REGISTRATION: Dutch trail register NTR6255 (NL6117) 08/02/2017 https://www.trialregister.nl/trial/6117.

Insight into Informant Discrepancies Regarding Psychosexual Functioning of Adolescents with and without Autism Spectrum Disorder.

The private nature of psychosexual functioning leads adolescents and their parents to have different perspectives, which highlights studying parent-child informant discrepancies in this domain. We investigated informant discrepancy in psychosexual functioning, using the self-report and parent report versions of the Teen Transition Inventory (TTI), of adolescents with autism spectrum disorder (ASD; 136 parent-child dyads) compared to adolescents from the general population (GP; 70 parent-child dyads). Significantly larger informant discrepancies exist in ASD dyads than GP dyads in most domains of psychosexual functioning, except for Body image, Sexual behavior, and Confidence in the future. It is important to use and pay attention to both informants, as discrepancies are relevant for both research and clinical practice regarding psychosexual functioning.

Dynamic Interactive Social Cognition Training in Virtual Reality (DiSCoVR) for social cognition and social functioning in people with a psychotic disorder: study protocol for a multicenter randomized controlled trial.

BACKGROUND: Problems in social functioning (e.g., unemployment, social isolation), are common in people with a psychotic disorder. Social cognition is a treatment target to improve social functioning, as it is a proximal predictor of social functioning. Social Cognition Training (SCT) improves social cognition, but may not generalize (enduringly) to social functioning, perhaps due to insufficient opportunity to practice in daily-life social situations. Using virtual reality (VR) for SCT could address this problem, as VR is customizable, accessible, and interactive. We will test the effect of a VR SCT, 'DiSCoVR', on social cognition and social functioning in a randomized controlled trial (RCT). METHODS: In total 100 people with a psychotic disorder and deficits in social cognition will be recruited for this multicenter randomized controlled trial (RCT). Participants will be randomized to VR SCT (DiSCoVR) or VR relaxation training (VRelax; active control). DiSCoVR is a 16-session individual SCT, consisting of three modules: 1) emotion perception (recognizing facial emotions in a virtual shopping street); 2) social perception and theory of mind (observing social interactions between virtual characters and assessing their behavior, emotions and thoughts); and 3) application of higher-order social cognition in social interaction (role-playing personalized situations in VR). People receiving VRelax complete sixteen individual sessions, in which they receive psycho-education about stress, identify personal stressors, learn relaxation techniques, and explore relaxing immersive virtual environments. Assessments will be performed at baseline, post-treatment, and 3-month follow-up. Primary outcomes are emotion perception (Ekman 60 Faces), social perception and theory of mind (The Awareness of Social Inference Test). Secondary outcomes include social functioning (Personal and Social Performance Scale), experiences and social interactions in daily life (experience sampling of emotions, social participation and subjective experience of social situations), psychiatric symptoms (e.g., depression, perceived stress, anxiety, positive and negative symptoms) and self-esteem. DISCUSSION: To our knowledge, this will be the first RCT testing the efficacy of VR SCT. It will also investigate generalization to daily life social situations, the durability of treatment effects, and moderators and mediators of treatment success. TRIAL REGISTRATION: On December 5, 2017, this trial was registered prospectively in the Dutch Trial Register as NTR6863 .

Gene × Environment contributions to autonomic stress reactivity in youth.

Dysregulated physiological stress reactivity has been suggested to impact the development of children and adolescents with important health consequences throughout the life span. Both environmental adversity and genetic predispositions can lead to physiological imbalances in stress systems, which in turn lead to developmental differences. We investigated genetic and environmental contributions to autonomic nervous system reactivity to a psychosocial stressor. Furthermore, we tested whether these effects were consistent with the differential susceptibility framework. Composite measures of adverse life events combined with socioeconomic status were constructed. Effects of these adversity scores in interaction with a polygenic score summarizing six genetic variants, which were hypothesized to work as susceptibility factors, were tested on autonomic nervous system measures as indexed by heart rate and heart rate variability. Results showed that carriers of more genetic variants and exposed to high adversity manifested enhanced heart rate variability reactivity to a psychosocial stressor compared to carriers of fewer genetic variants. Conversely, the stress procedure elicited a more moderate response in these individuals compared to carriers of fewer variants when adversity was low.

Examining bidirectional effects between the autism spectrum disorder (ASD) core symptom domains and anxiety in children with ASD.

BACKGROUND: Although a bidirectional relationship between autism spectrum disorder (ASD) and anxiety symptoms is assumed, few studies have investigated this. Moreover, little is known about potential differential relationships of the two core symptom domains of ASD - social communication impairment and restricted, repetitive behavior - with anxiety over time. METHOD: Participants were 130 children with an ASD (M age 6.7 years, 81.5% boys) of whom 79 participated in a follow-up assessment 2 years later. We used cross-lagged models to test whether social communication impairment and restricted, repetitive behavior at T0 predicted anxiety at T2 and vice versa. RESULTS: Crossed-lagged models showed that anxiety symptoms predicted social communication impairment over time (ß = .22, p = .008), but not vice versa (ß = -.07, p = .49). There were no significant paths from anxiety symptoms to later restricted, repetitive behavior (ß = .11, p = .34) or vice versa (ß = -.11, p = .27). CONCLUSIONS: Our results do not support a bidirectional relationship between the ASD core symptom domains and anxiety, but suggest that higher levels of anxiety symptoms increase the risk of more social communication impairment over time in children with ASD. This underlines the importance of treating anxiety symptoms to improve both social and emotional functioning.

A randomized controlled trial to examine the effects of the Tackling Teenage psychosexual training program for adolescents with autism spectrum disorder.

BACKGROUND: Previous research underscores the importance of psychosexual guidance for adolescents with autism spectrum disorder (ASD). Such guidance is provided in the Tackling Teenage Training (TTT) program, in which adolescents with ASD receive psycho-education and practice communicative skills regarding topics related to puberty, sexuality, and intimate relationships. This randomized controlled trial investigated the effects of the TTT program on (a) cognitive outcomes (i.e. psychosexual knowledge, and insight in interpersonal boundaries) and (b) behavioral outcomes (i.e. skills needed for romantic relationships and problematic sexual behavior). METHODS: A total of 189 cognitively able adolescents with ASD, aged 12-18 years old, were randomized to an intervention condition (n = 95) or a waiting-list control condition (n = 94). We assessed outcomes using self-reported as well as parent-reported questionnaires at baseline (T1), posttreatment (T2; after 6 months), and follow-up (T3; after 12 months). RESULTS: Linear mixed model analyses showed significant treatment effects for psychosexual knowledge and adequate insight in boundaries, both posttreatment and at follow-up. All adolescents increased significantly over time in their social responsiveness and decreased their problematic sexual behavior, irrespectively of condition. The TTT program was most effective for younger adolescents with ASD; following the TTT program resulted in higher psychosexual knowledge, and higher social functioning for these adolescents. CONCLUSIONS: The results of this study indicate that the TTT program is effective as a psycho-educational program to provide adolescents with ASD with the knowledge and insight they need to prepare themselves for a healthy psychosexual development. Further research is needed to investigate how this increased knowledge and insight can subsequently ameliorate improvements in romantic skills and prevent the development of problematic sexual behavior and victimization.

Symptoms of autism spectrum disorder and anxiety: shared familial transmission and cross-assortative mating.

BACKGROUND: In order to shed more light on the frequent co-occurrence of Autism Spectrum Disorder (ASD) and anxiety in children, the aims of the study were (a) to examine whether ASD and anxiety share familial transmission indicated by cross-symptom associations between parental and children's symptoms (e.g., parental anxiety predicting children's ASD) in addition to associations for similar symptoms; (b) to investigate the possibility that cross-assortative mating (i.e., whether ASD symptoms in one parent are positively associated with anxiety symptoms in the other parent) increases the risk for both ASD and anxiety in children. METHOD: In 231 families of clinically referred children, parents rated both their own and the other parent's ASD and anxiety symptoms and one parent those of the index child and siblings (n = 447, aged 2.5-18 years). ASD symptoms were assessed using the Social Responsiveness Scale (SRS-2) and anxiety symptoms using the Achenbach System of Empirically Based Assessment (ASEBA) instruments. RESULTS: Parental ASD and anxiety symptoms predicted similar symptoms in children, dependent on the informant type. Additionally, parental anxiety symptoms across both self-report and informant-report predicted children's ASD symptoms and maternal self-reported ASD symptoms predicted children's anxiety symptoms. ASD and anxiety symptoms were correlated within parents, but we found only one cross-symptom association between parents. CONCLUSIONS: Cross-symptom associations between parental and children's ASD and anxiety symptoms suggest shared familial transmission of ASD and anxiety, but further research is needed to clarify the underlying mechanisms. Cross-assortative mating does not seem a likely explanation for the co-occurrence of ASD and anxiety in children.

Maternal C-Reactive Protein Concentration in Early Pregnancy and Child Autistic Traits in the General Population.

BACKGROUND: Exposure to elevated levels of inflammatory markers during pregnancy has been suggested as possible aetiologic factor in the occurrence of autism spectrum disorder (ASD). In this study, we investigated the prospective relation between maternal C-reactive protein (CRP) during early pregnancy and children's autistic traits in the general population. METHODS: In a large population-based cohort in the Netherlands, we measured maternal CRP levels before 18 weeks of gestation (N = 4165). Parents reported on their children's autistic traits at age 6 years using the Social Responsiveness Scale, and the Pervasive Developmental Problem scale. Regression models were used to examine the relation between maternal CRP levels and autistic traits in children. RESULTS: Compared with the reference group (CRP < 2.3 mg/L), elevated levels of CRP (>7.8 mg/L) in pregnant women were associated with higher Social Responsiveness Scale scores in children [ß = 0.055, 95% confidence interval (CI) 0.033, 0.078]; however, the effect was strongly attenuated after adjustment for several socioeconomic factors and in particular by maternal health-related factors including body mass index (fully adjusted model ß = 0.018, 95% CI -0.005, 0.042). We found no relation between maternal CRP levels and pervasive developmental problem. CONCLUSIONS: Our results suggest that the association between elevated levels of maternal CRP in pregnancy and autistic traits in children is confounded by maternal health-related and socioeconomic factors. Further studies are needed to explore whether other maternal inflammatory markers during pregnancy, as a response to maternal inflammation, are associated with the development of autistic traits in the offspring.

Study protocol: a randomized controlled trial investigating the effects of a psychosexual training program for adolescents with autism spectrum disorder.

BACKGROUND: Previous research shows that adolescents with autism spectrum disorder (ASD) run several risks in their psychosexual development and that these adolescents can have limited access to reliable information on puberty and sexuality, emphasizing the need for specific guidance of adolescents with ASD in their psychosexual development. Few studies have investigated the effects of psychosexual training programs for adolescents with ASD and to date no randomized controlled trials are available to study the effects of psychosexual interventions for this target group. METHODS/DESIGN: The randomized controlled trial (RCT) described in this study protocol aims to investigate the effects of the Tackling Teenage Training (TTT) program on the psychosexual development of adolescents with ASD. This parallel clinical trial, conducted in the South-West of the Netherlands, has a simple equal randomization design with an intervention and a waiting-list control condition. Two hundred adolescents and their parents participate in this study. We assess the participants in both conditions using self-report as well as parent-report questionnaires at three time points during 1 year: at baseline (T1), post-treatment (T2), and for follow-up (T3). DISCUSSION: To our knowledge, the current study is the first that uses a randomized controlled design to study the effects of a psychosexual training program for adolescents with ASD. It has a number of methodological strengths, namely a large sample size, a wide range of functionally relevant outcome measures, the use of multiple informants, and a standardized research and intervention protocol. Also some limitations of the described study are identified, for instance not making a comparison between two treatment conditions, and no use of blinded observational measures to investigate the ecological validity of the research results.

Formal thought disorder in autism spectrum disorder predicts future symptom severity, but not psychosis prodrome.

Formal thought disorder (FTD) is a disruption in the flow of thought, which is inferred from disorganisation of spoken language. FTD in autism spectrum disorders (ASD) might be a precursor of psychotic disorders or a manifestation of ASD symptom severity. The current longitudinal study is a seven-year follow-up of 91 individuals aged 5-12 years with ASD. We tested (1) whether childhood FTD predicted prodromal symptoms of psychosis in adolescence and (2) whether childhood FTD was associated with greater ASD symptom severity in adolescence. ASD symptom severity was assessed in childhood (T1) and 7 years later (T2), using the autism diagnostic observation schedule (ADOS). At T1, the Kiddie-Formal Thought Disorder Rating Scale (KFTDS) was used to measure symptoms of FTD. At T2, the prodromal questionnaire (PQ) was used to assess prodromal symptoms of psychosis. FTD at T1 did not predict prodromal symptoms of psychosis at T2 in children with ASD. FTD symptoms at T1, namely illogical thinking, predicted ASD symptom severity at T2 and this effect remained significant after controlling for T1 ASD symptom severity. In children with ASD, illogical thinking predicts severity of ASD symptoms in adolescence, but FTD does not predict prodromal symptoms of psychosis.

Parental rearing behavior prospectively predicts adolescents' risky decision-making and feedback-related electrical brain activity.

The present study examined the role of parental rearing behavior in adolescents' risky decision-making and the brain's feedback processing mechanisms. Healthy adolescent participants (n = 110) completed the EMBU-C, a self-report questionnaire on perceived parental rearing behaviors between 2006 and 2008 (T1). Subsequently, after an average of 3.5 years, we assessed (a) risky decision-making during performance of the Balloon Analogue Risk Task (BART); (b) event-related brain potentials (ERPs) elicited by positive (gain) and negative feedback (loss) during the BART; and (c) self-reported substance use behavior (T2). Age-corrected regression analyses showed that parental rejection at T1 accounted for a unique and significant proportion of the variance in risk-taking during the BART; the more adolescents perceived their parents as rejecting, the more risky decisions were made. Higher levels of perceived emotional warmth predicted increased P300 amplitudes in response to positive feedback at T2. Moreover, these larger P300 amplitudes (gain) significantly predicted risky decision-making during the BART. Parental rearing behaviors during childhood thus seem to be significant predictors of both behavioral and electrophysiological indices of risky decision-making in adolescence several years later. This is in keeping with the notion that environmental factors such as parental rearing are important in explaining adolescents' risk-taking propensities.

Blunted feedback processing during risky decision making in adolescents with a parental history of substance use disorders.

Risky decision making, a hallmark phenotype of substance use disorders (SUD), is thought to be associated with deficient feedback processing. Whether these aberrations are present prior to SUD onset or reflect merely a consequence of chronic substance use on the brain remains unclear. The present study investigated whether blunted feedback processing during risky decision making reflects a biological predisposition to SUD. We assessed event-related potentials elicited by positive and negative feedback during performance of a modified version of the Balloon Analogue Risk Task (BART) among high-risk adolescents with a parental history of SUD (HR; n = 61) and normal-risk controls (NR; n = 91). HR males made significantly more risky and faster decisions during the BART than did NR controls. Moreover, HR adolescents showed significantly reduced P300 amplitudes in response to both positive and negative feedback as compared to NR controls. These differences were not secondary to prolonged substance use exposure. Results are discussed in terms of feedback-specific processes. Reduced P300 amplitudes in the BART may reflect poor processing of feedback at the level of overall salience, which may keep people from effectively predicting the probability of future gains and losses. Though conclusions are tentative, blunted feedback processing during risky decision making may represent a promising endophenotypic vulnerability marker for SUD.

Diminished error-related brain activity as a promising endophenotype for substance-use disorders: evidence from high-risk offspring.

One of the core features of individuals with a substance-use disorder (SUD) is the reduced ability to successfully process errors and monitor performance, as reflected by diminished error-related negativities (ERN). However, whether these error-related brain abnormalities are caused by chronic substance use or rather predates it remains unclear. The present study elucidated whether hypoactive performance monitoring represents an endophenotypic vulnerability marker for SUD by using a high-risk paradigm. We assessed the behavioral components of error-processing, as well as the amplitude of the ERN in the event-related brain potential (ERP) during performance of the Eriksen Flanker Task among high-risk adolescents of parents with a SUD (HR; n = 28) and normal-risk controls (NR; n = 40). Results revealed that HR offspring were characterized by a higher prevalence of internalizing symptoms and more frequent cannabis use, the latter having a significant influence on the ERN. Interestingly, risk group uniquely predicted the negativity amplitude in response to error trials above and beyond confounding variables. Moreover, we found evidence of smaller ERN amplitudes in (cannabis use-naïve) HR offspring, reflecting impaired early processing of error information and suboptimal performance monitoring, whereas no robust group differences were found for overall behavioral performance. This effect was independent of an overall reduction in brain activity. Taken together, although we cannot rule out alternative explanations, the results of our study may provide evidence for the idea that diminished error-processing represents a promising endophenotype for SUD that may indicate a vulnerability to the disorder.

Psychometric Properties of Psychosexual Functioning Survey Among Autistic and Non-autistic Adults: Adapting the Self-Report Teen Transition Inventory to the U.S. Context.

Psychosexual functioning is an important aspect of human development and relationships. A previous study investigated psychosexual functioning of autistic adolescents using the Teen Transition Inventory (TTI), but there is a lack of comprehensive measurement of psychosexual functioning among autistic and non-autistic (NA) adults. To address this gap, the current study adapted the self-report TTI to the Psychosexual Functioning Survey (PSFS) and presented it to 131 autistic (n = 59) and NA adults (n = 72) in the U.S. Comparisons of psychometric properties between the original TTI and the PSFS are shared; the developmental relevancy among some items was changed, and the alphas indicated a difference in the content of certain scales. Differences emerged between autistic and NA adults in both the intra- and interpersonal domains of psychosexual functioning, but not in sexual and intimate behaviors. The findings suggest the persistence of differences from adolescence to adulthood between autistic and NA people and highlight the importance of understanding the unique experiences of adults in psychosexual functioning relative to diagnostic status.

Adapting the Tackling Teenage Training Sex Education Program for Autistic Adults in the US: A Pilot Study.

Despite the established need for sexuality and relationship programming for autistic adults, there are extremely limited curricula for this population. This pilot study used an evidence-based sexuality and relationship education program for autistic adolescents (Tackling Teenage Training) as the basis for an adult-focused virtual psychoeducational group. Qualitative feedback, quantitative ratings of the programming, and behavioral surveys from participants were collected. Nine participants completed the program, and corresponding pre and post measures. Highly rated topics, for example gender identity and online dating, were consistent with previous research on what autistic adults want from a sexuality and relationship education program. Future programming should incorporate increased attention to themes and topics highlighted by participants, and should utilize the teaching tools (e.g., role play, peer discussions) identified as useful by the participants.

Sex differences in the course of autistic and co-occurring psychopathological symptoms in adolescents with and without autism spectrum disorder.

LAY ABSTRACT: There is an ongoing debate as to whether autism spectrum disorder (ASD) is expressed differently in women than men. Studies on sex differences in autistic symptoms and symptoms of other psychiatric problems present in individuals with autism generally do not include a general population comparison group, making it unclear whether differences are specific to autism or merely reflecting development in the general population. In this study, we compared sex differences in the course of autistic and at the same time present symptoms of other psychiatric problems in adolescents with milder forms of ASD to those in a group of the general population with an equal intelligence quotient (IQ) and socioeconomic status. Data of five assessment moments from ages 11 to 22 years were analyzed using a statistic procedure that allowed us to determine which factors affect the course of symptoms over time. We found that in adolescence, sex differences in the course of psychopathological symptoms specific for autism are confined to the repetitive stereotyped domains. Males had higher scores on the sensory/stereotypic and resistance to change domains, the latter difference disappeared during the course of adolescence due to an increase of these problems in autistic females. Other sex differences, among which an increase over time in mood and anxiety problems in females was the most outstanding, were also observed in females without autism. These sex-specific differences have relevance in the clinical care of autistic men and women, although they are subtle compared to differences between individuals with and without autism.

Psychometric Properties of the Dutch Contextual Assessment of Social Skills (CASS): An Independent Observational Outcome Measure of Social Skills in Autistic Adolescents.

The goal of this study was to translate and adapt the original 9-item of the Contextual Assessment of Social Skills (CASS) to a Dutch version and assess its psychometric qualities. Autistic adolescents aged 12 to 18 years (n = 99) took part in a randomized controlled trial. In this study, pre-intervention data were utilized. The original CASS was adapted to ensure cultural relevance and the content validity was assessed. Data was used to assess reliability and structural validity, using confirmatory factor analysis. 4-item were added to the CASS during the adaptation to better align with the objectives of the experimental intervention. The original 9-item had inter-item correlations between .01 and .70. The Cronbach's alpha for the original 4-item total score was moderate (α = .69), while for a 7-item total score, it was high (α = .86). This 7-item total score had a sufficient model fit (Comparative Fit Index = .90). This total score had a significant correlation with the Assertion subscale of the Social Skills Improvement System-Adolescent (SSIS-A) (r = 0.26, p < .01), and the Social Responsiveness Scale-2 (SRS-2) total score (r = - .21, p = .04) indicating sufficient convergent validity. The CASS total score was not correlated with the Repetitive and Restricted Behavior scale of the SRS-2 (r = - .08, p = .43), indicating sufficient divergent validity. The Dutch CASS can be considered a conceptually sound and reliable observational instrument for assessing social conversational skills in Dutch autistic youth. Further evaluation of its feasibility when implemented in practice, outside of clinical research, is needed.Trial registration: Dutch trail register NTR6255 (NL6117) 08/02/2017 https://www.trialregister.nl/trial/6117.

Perspectives on Autism Spectrum Disorder Diagnosis, Symptoms, Treatment and Gender Roles: A Qualitative Study of Similarities and Differences between Sexes.

This study aims to compare the experiences of women and men of different age groups with regard to their first autism spectrum disorder (ASD) diagnosis, symptoms, treatment, and gender roles to inform our understanding in clinical practice of differences as well as similarities. Semi-structured interviews were conducted amongst 22 women (n = 12) and men (n = 10) in three adult age groups regarding their diagnostic process, symptoms, treatment, and gender roles. Participants also filled out questionnaires on gender traits, social support, coping, and quality of life. Framework analysis guidelines were followed to identify subthemes within the three pre-defined key themes of the semi-structured interviews, and quantitative analyses were performed on the questionnaire results. Women often had caregiver roles and were more focused on social and family-oriented life aspects than men. Family and societal expectations may have been different for women from an early age onward and were considered burdensome by some, but not all. Views on ASD diagnosis, symptoms, and treatment were largely individually determined. The questionnaire results mostly showed no significant sex differences. Perceived gender roles differed between participants. In diagnosis and treatment, awareness of general gender differences and gender roles is important, but inter-individual differences and similar experiences in men should not be overlooked.
