Titre : An exploration of the judgement of sexual situations by adolescents with autism spectrum disorders versus typically developing adolescents Type de document : Texte imprimé et/ou numérique Auteurs : Kirsten VISSER, Auteur ; Kirstin GREAVES-LORD, Auteur ; Nouchka T. TICK, Auteur ; Frank C. VERHULST, Auteur ; Athanasios MARAS, Auteur ; Esther J. M. VAN DER VEGT, Auteur Article en page(s) : p.35-43 Langues : Anglais (eng) Mots-clés : ASD Psychosexual development Adolescence Inappropriate sexual behaviour Index. décimale : PER Périodiques Résumé : Inappropriate sexual behaviour, sexual problems and sexual victimization in adolescents with autism spectrum disorders (ASD) is regularly reported in previous research, but little is known about factors associated with these problems, nor about factors associated with a healthy sexuality development in adolescents with ASD. Investigating the judgement of sexual behaviour can be a first step in acquiring insight into inappropriate sexual behaviour in adolescents with ASD. Methods We assessed how 94 cognitively-able adolescents with ASD and 94 typically developing (TD) adolescents judged the appropriateness of different illustrations of sexual situations and we investigated the differences between the two groups. Results The highest level of agreement between the judgements of adolescents with ASD and the judgements of an expert panel was found for severely inappropriate sexual behaviours (89.2%) and the lowest agreement was found for appropriate (31.7%) and slightly inappropriate sexual behaviours (26.1%). No significant differences were found between the judgements of the adolescents with ASD and the TD adolescents. Regarding the divergent judgements, adolescents with and without ASD were mostly more strict (i.e., more conservative) than the expert panel in their judgement of sexual situations. Finally, a small percentage of adolescents with and without ASD showed milder (i.e., less conservative) judgements of sexual situations portraying behaviour that was considered severely inappropriate by an expert panel. Conclusions Our findings showed that, overall, judgement of illustrations of sexual situations does not seem to be hampered in adolescents with ASD. More research is needed to clarify whether this also holds true for their judgements of – and actions in – more complex real life situations.

Titre : Associations between autism traits and family functioning over time in autistic and non-autistic children Type de document : Texte imprimé et/ou numérique Auteurs : Leontine W TEN HOOPEN, Auteur ; Pieter FA DE NIJS, Auteur ; Geerte SLAPPENDEL, Auteur ; Jan VAN DER ENDE, Auteur ; Dennis BASTIAANSEN, Auteur ; Kirstin GREAVES-LORD, Auteur ; Leona HAKKAART-VAN ROIJEN, Auteur ; Manon HJ HILLEGERS, Auteur Article en page(s) : p.2035-2047 Langues : Anglais (eng) Mots-clés : autism caregivers children family functioning longitudinal parenting traits Index. décimale : PER Périodiques Résumé : To explore associations between autism traits and family functioning over time, we studied longitudinal data of a mixed group of 168 clinically referred autistic and non-autistic children. Cross-lagged models showed a significant association between fewer autism traits at the diagnostic assessment and better family functioning 1?year later for the whole group, independently of children?s internalizing or externalizing behavior. When splitting the group into autistic children (58%) and non-autistic children (42%) based on an autism diagnosis, this association was only significant in the subgroup of non-autistic children with autism traits. We hypothesized that the needs of families experiencing difficulty understanding and adjusting to their children with autism traits, but no clinical autism diagnosis, might be unmet without the training or support facilities offered to families with autistic children. Although further research is needed to explore this association, clinicians may also consider supporting families of non-autistic children with autism traits to prevent family functioning problems. Because high autism trait levels in non-autistic children may be of a different origin than autism, for example, other neurodevelopmental or mental health problems, family training or support should be tailored to the child?s underlying difficulties.Lay AbstractLittle is known about family functioning over time when raising a child with autism traits, with or without a clinical autism diagnosis. Therefore, we asked caregivers-mostly parents-of a group of 168 children about the family functioning and the child?s emotional and behavioral characteristics, as well as autistic traits, twice with about 1?year in between. For numerous reasons, the children were referred to youth mental health care centers, including child and adolescent psychiatric services. Care as usual was offered after the diagnostic assessment if a clinical diagnosis was the assessment outcome. Caregivers reported less problematic family functioning in children with fewer autism traits over time. The child?s additional emotional or behavioral characteristics did not seem to influence this relation. Furthermore, we split the whole group into autistic children with a clinical autism diagnosis (58%) and non-autistic children with autism traits but without a clinical diagnosis (42%) to see whether we would find the same results in both groups. Surprisingly, the relation between family functioning and the level of a child?s autism traits only held for the subgroup of non-autistic children with autism traits. Thus, raising children with autism traits without a clinical diagnosis may affect family functioning over time. We think that families might have difficulty understanding and adjusting to the autism traits of their children but are lacking the support that is exclusively offered to families of children with a clinical autism diagnosis. We must be cautious because we do not know whether there is a causal relation. Although further research is needed to explore and learn to understand this result, clinicians might consider offering support to families of children with subthreshold autism to prevent problems in family functioning. Because high autism trait levels in non-autistic children may be of a different origin than autism, for example, other neurodevelopmental or mental health problems, family training or support should be tailored to the child?s underlying difficulties.

Investigating autonomic and subjective responses to social vs. nonsocial stimuli may help to reveal underlying mechanisms of these atypical responses. This study examined autonomic responses (skin conductance level and heart rate) and subjective responses to social vs. nonsocial pictures in 37 adolescents with an ASD and 36 typically developing (TD) adolescents. Thirty-six pictures from the International Affective Picture System were presented, divided into six categories based on social content (social vs. nonsocial) and pleasantness (pleasant, neutral, and unpleasant). Both in adolescents with ASD as well as TD adolescents, pictures with a social content resulted in higher skin conductance responses (SCRs) for pleasant and unpleasant pictures than for neutral pictures. No differences in SCRs were found for the three nonsocial picture categories. Unpleasant pictures, both with and without a social content, showed more heart rate deceleration than neutral pictures. Self-reported arousal ratings were influenced by the social and affective content of a picture. No differences were found between individuals with ASD and TD individuals in their autonomic and subjective responses to the picture categories. These results suggest that adolescents with ASD do not show atypical autonomic or subjective responses to pictures with and without a social content. These findings make it less likely that impairments in social information processing in individuals with ASD can be explained by atypical autonomic responses to social stimuli.

Titre : Blunted feedback processing during risky decision making in adolescents with a parental history of substance use disorders Type de document : Texte imprimé et/ou numérique Auteurs : Anja S. EUSER, Auteur ; Kirstin GREAVES-LORD, Auteur ; Michael J. CROWLEY, Auteur ; Brittany E. EVANS, Auteur ; Anja C. HUIZINK, Auteur ; Ingmar H. A. FRANKEN, Auteur Article en page(s) : p.1119-1136 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : 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.
