Accuracy of initial diagnostic impressions of autism in toddlers and behaviors that inform these impressions / Rebecca P. THOMAS in Autism Research, 17-3 (March 2024)  

Public ISBD [article]  inAutism Research > 17-3 (March 2024) . - p.568-583 Titre : Accuracy of initial diagnostic impressions of autism in toddlers and behaviors that inform these impressions Type de document : Texte imprimé et/ou numérique Auteurs : Rebecca P.

ROBINS, Auteur ; Deborah A. FEIN, Auteur Article en page(s) : p.568-583 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Clinicians form initial impressions about a child's diagnosis based on behavioral features, but research has not yet identified specific behaviors to guide initial diagnostic impressions. Participants were toddlers (N = 55, mean age 22.9?months) from a multi-site early detection study, referred for concern for ASD due to screening or parent/provider concern. Within 5?min of meeting a child, clinicians noted ASD or non-ASD impression, confidence in impression, and behaviors that informed their impression. These clinicians also determined final diagnoses for each child. When a child's final diagnosis was ASD (n = 35), senior clinicians formed an initial impression of ASD in 22 cases (63%) but missed 13 cases (37%). When final diagnosis was non-ASD (n = 20), senior clinicians made an initial impression of non-ASD in all cases (100%). Results were similar among junior clinicians. Senior and junior clinicians used the same behaviors to form accurate impressions of ASD and non-ASD: social reciprocity, nonverbal communication, and eye contact. Senior clinicians additionally used focus of attention when forming accurate impressions of ASD and non-ASD; junior clinicians used this behavior only when forming accurate non-ASD impressions. Clinicians' initial impressions of ASD are very likely to be consistent with final diagnoses, but initial impressions of non-ASD need follow-up. Toddlers who show all four atypical behaviors (social reciprocity, nonverbal communication, eye contact, and focus of attention) might receive expedited ASD diagnoses. However, presence of apparently typical behaviors should not rule out ASD; for some children a longer evaluation is necessary to allow for more opportunities to observe subtle social behavior.

Categorizing and identifying preferred interests in autistic toddlers / Kirsty L. COULTER ; Rebecca P. THOMAS ; Marianne L. BARTON ; Diana L. ROBINS ; Deborah A. FEIN in Autism Research, 17-7 (July 2024)  

Public ISBD [article]  inAutism Research > 17-7 (July 2024) . - p.1487-1500 Titre : Categorizing and identifying preferred interests in autistic toddlers Type de document : Texte imprimé et/ou numérique Auteurs : Kirsty L. COULTER, Auteur ; Rebecca P. THOMAS, Auteur ; Marianne L. BARTON, Auteur ; Diana L. ROBINS, Auteur ; Deborah A. FEIN, Auteur Article en page(s) : p.1487-1500 Langues : Anglais (eng) Index. décimale : PER Périodiques Résumé : Abstract Preferred interests are characteristic of autism spectrum disorder and are reported by parents starting at an early age. However, limited research has explored the presentation of preferred interests in toddlerhood. Previous literature suggests that both the intensity and type of preferred interests held by autistic individuals differ from those held by peers with developmental delay and no diagnosis and that autistic interests are more unusual in nature. While preferred interests are seen in typical child development, previous research suggests that the presence of preferred interests in children with no diagnosis declines with age. Literature also indicates that the sex and cognitive ability of autistic children influences preferred interests. Identification of early preferred interests commonly held by autistic toddlers could serve as a useful clinical indicator of future diagnosis. This article explored whether diagnostic group, age, sex, and cognitive ability predict the likelihood that parents reported preferred interests in children aged 12-36?months with diagnoses of autism, developmental delay, and those with no diagnosis. Additionally, we explored potential diagnostic group differences in interest type. Results suggest that diagnostic group, but not age, sex, or cognitive ability, predicts the likelihood that parents report preferred interests. No differences in the type of interests among diagnostic groups were identified. These results support the use of preferred interests as an early sign of autism but suggest that interest type may not be a helpful clinical indicator of autism in toddlerhood.

Cognitive and Adaptive Skills in Toddlers Who Meet Criteria for Autism in DSM-IV but not DSM-5 / Dasal Tenzin JASHAR in Journal of Autism and Developmental Disorders, 46-12 (December 2016)

The toddlers in the DSM-IV only group were less delayed on various domains of adaptive (Communication, Socialization) and cognitive (Expressive and Receptive language, Fine Motor, Visual Reception) skills, and had less severe symptoms of ASD than the DSM-5 group. Thus, they might have the best potential for successful intervention. The DSM-IV only group did not differ from the non-ASD group in any adaptive or cognitive skills except for socialization skills, the hallmark of ASD.

Comparison of the Modified Checklist for Autism in Toddlers, Revised with Follow-Up (M-CHAT-R/F) Positive Predictive Value by Race / Yael G. DAI in Journal of Autism and Developmental Disorders, 51-3 (March 2021)

Index. décimale : PER Périodiques Résumé : The Modified Checklist for Autism in Toddlers, Revised, with Follow-Up (M-CHAT-R/F) is the most widely used screener for ASD. Despite the comparable rate of ASD in Black and White children, the M-CHAT-R/F was validated on a primarily White, Non-Hispanic sample. Few studies have assessed whether the screener performs adequately with racial minorities. This study compared the M-CHAT-R/F Positive Predictive Value (PPV), for ASD, and for any developmental condition, in Black and White children. We also examined M-CHAT-R/F item-level PPV by race. The PPVs for ASD and other developmental disorders were similar in both racial groups for total score and individual items. Therefore, our findings support the use of the M-CHAT-R/F with Black and White children.

At age 2, Cluster 1 demonstrated few autism symptoms and high cognitive scores; 60 % no longer met criteria for PDD at 4. Cluster 2 exhibited more autism symptoms and lower cognitive scores at 2; 89.5 % met criteria for ASD at 4. Cluster 3 had the lowest cognitive scores and most impaired social/communication skills at 2, but no repetitive behaviors; 60 % diagnosed with Autistic Disorder at 4. Results shed light on outcomes for different PDD-NOS types and raise questions regarding the increased importance of repetitive behaviors in DSM-5.
