Few studies have examined differences in autism spectrum disorder (ASD) phenotype between children from multiplex and simplex families at the time of diagnosis. The present study used an age- and gender-matched, community-based sample (n = 105) from the southwestern United States to examine differences in ASD symptom severity, cognitive development, and adaptive functioning. No significant differences between children from multiplex and simplex families were observed. Exploratory analysis revealed that parents underreported receptive and expressive language and fine motor skills compared to professional observation, especially among children from multiplex families. These findings suggest that diagnosticians may need to consider family structure when choosing and interpreting assessments of receptive language, expressive language, and fine motor skills.

Evidence supporting the effectiveness of the PEERS® social skills intervention for adolescents with autism spectrum disorder is relatively strong. Less is known about whether the duration of the program impacts participant outcomes. The current study compared outcomes of participants randomly assigned to participate in an accelerated version of PEERS that met twice weekly for 7 weeks (n = 11) or the traditional PEERS program that met once weekly for 14 weeks (n = 10). The accelerated PEERS group demonstrated improvements consistent with previous research on the program, and treatment response did not differ significantly between the accelerated PEERS and traditional PEERS groups. Together, findings provide preliminary evidence that PEERS is effective when administered as a 7-week program. [ABSTRACT FROM AUTHOR]

This study compared immediate and 4-month outcomes among adolescents with autism spectrum disorder randomly assigned to the PEERS curriculum (n = 10), a peer mediated PEERS curriculum (n = 12), or a delayed treatment control group (n = 12). Findings suggest a modest advantage in social skills knowledge and social functioning for participants in the peer-mediated PEERS curriculum relative to Traditional PEERS, and gains in social skills knowledge, social functioning, and reductions in loneliness were maintained in one or both treatment groups at a 4-month follow-up. Typically developing peer mentors (n = 16) showed improvements in social skills knowledge and marginal improvements in autism knowledge and loneliness. Future research with a larger sample and objective outcome measures is needed. [ABSTRACT FROM AUTHOR]

The male-to-female (M:F) ratio for autism spectrum disorders (ASD), typically about 4:1, appears to decrease with increasing paternal age, but this relationship has not been systematically tested. With 393 ASD cases from families with two or more ASD cases, we categorized paternal age into five age groups (<30, 30–34, 35–39, 40–44, 45+) and found that the M:F ratio was significantly decreased with increasing paternal age groups and remained so after also adjusting for maternal age. No significant relationship between maternal age group and the M:F ratio was observed. This study suggests that the M:F ratio is reduced with increasing paternal age consistent with de novo genetic or genomic anomalies arising more frequently as men age and then conceive children.

Purpose: Most assessment tools used to diagnose and characterize autism spectrum disorder (ASD) were developed for in-person administration. The coronavirus disease 2019 (COVID-19) pandemic resulted in the need to adapt traditional assessment tools for online administration with only minimal evidence to support validity of such practices. Methods: The current exploratory study compared scores from online administration of the Kaufman Brief Intelligence Test, Second Edition (KBIT-2) during the pandemic to scores derived from follow-up testing using traditional in-person administration. Participants were 47 children and adolescents (M age = 9.48 years, SD = 4.06; 68.10% male) who participated in a telehealth diagnostic evaluation for ASD that included online administration of the KBIT-2. Participants were invited to complete the KBIT-2 a second time during an in-person study visit. Results: Pearson’s correlation coefficients suggested acceptable to good reliability between online and in-person administration. Although most participants’ online and in-person scores were within one standard deviation of each other, results suggested statistically significant differences between scores derived from the two modalities. Additionally, 19–26% of participants (depending on domain examined) had scores that differed by more than one standard deviation. Notably, all but one of these participants was under the age of 12 years. Conclusion: Findings suggest that online administration of the KBIT-2 is likely appropriate for older children and adolescents with ASD. However, additional research is needed to test online administration of intellectual assessments for children with ASD. [ABSTRACT FROM AUTHOR]

Use of telehealth assessments for toddlers at increased likelihood of autism spectrum disorder (ASD) began prior to the global COVID-19 pandemic; however, the value of telehealth assessments as an alternative to in-person assessment (IPA) became clearer during the pandemic. The Naturalistic Observation Diagnosis Assessment (NODA™), previously demonstrated as a valid and reliable tool to evaluate asynchronous behaviors for early diagnosis, was enhanced to add synchronous collection of behaviors to assist clinicians in making a differential diagnosis of ASD. This study was conducted to validate the information gathered through NODA-Enhanced (NODA-E™) as compared to a gold standard IPA. Forty-nine toddlers aged 16.0–32.1 months of age, recruited through community pediatric offices and a tertiary ASD clinic, participated in both NODA-E and IPA assessments. There was high agreement between the two assessment protocols for overall diagnosis (46 of 49 cases; 93.6%; κ = .878), specific diagnostic criteria for social communication and social interaction (SCI; range 95.9–98%; κ = .918—.959), and for two of four criteria specified for restricted and repetitive behaviors (RRB; range 87.8–98%; κ = .755 and .959). There was lower agreement for two subcategories of RRBs (range 65.3–67.3%; κ = .306 and .347). NODA-E is a tool that can assist clinicians in making reliable and valid early ASD diagnoses using both asynchronous and synchronous information gathered via telehealth and offers an additional tool within a clinician’s assessment toolbox.
