However, change sensitivity has not been systematically investigated among commonly used measures, albeit its importance for clinical trials and longitudinal studies. Methods Longitudinal data resulting from behavioural observation (Autism Diagnostic Observation Schedule-2, ADOS-2; Brief Observation of Social Communication Change, BOSCC) and parent report (Restricted Behaviour Scale-Revised, RBS-R) was collected for 134 toddlers and preschoolers aged 25?65?months diagnosed with ASD by the Autism Diagnostic Interview-Revised (ADI-R) and ADOS-2. Change sensitivity was estimated using the reliable-change index and developmental trajectories of RRB by linear mixed models and k-means clustering. Results The RBS-R identified significantly more reliable change in RRB severity compared to ADOS-2 and BOSCC. For all measures, except the RBS-R self-injurious behaviour subscale, three distinct RRB trajectories were found as follows: increasing, stable and decreasing RRB severity. Overlap was low between trajectory group assignment across measures, as were cross-sectional correlations between ADI-R, ADOS-2, BOSCC and RBS-R. Trajectory group comparisons among measures mostly showed lower baseline RRB severity in the increasing trajectory groups and higher baseline RRB severity in the decreasing trajectory groups. The trajectory groups did not differ in age or nonverbal IQ across RRB measures, except for the RBS-R compulsive behaviour subscale, which had higher nonverbal IQ in the decreasing trajectory group. Conclusions The dimensional questionnaire RBS-R compared to ADOS-2 and BOSCC is superior in capturing subtle changes in RRB during preschool age.

Complex, low-intensity, individualised naturalistic developmental behavioural intervention in toddlers and pre-schoolers with autism spectrum disorder: The multicentre, observer-blind, parallel-group randomised-controlled A-FFIP trial / Christine M.

Here, we study efficacy of the low-intensity, complex NDBI ?Frankfurt Early Intervention Program for ASD? (A-FFIP) over 1 year by a confirmatory phase-III, prospective, randomised, controlled, parallel-group study with two treatment arms over four centres. Methods Main inclusion criteria: ASD (DSM-5), age 24 66 months, developmental quotient >30. Intervention: Manualised A-FFIP intervention. Control intervention: Early intervention as usual (EIAU). Primary outcome: Change in core ASD symptoms from baseline (T2) to immediate intervention endpoint at 12 months (T6) based on the blindly rated Brief Observation for Communication Change (BOSCC) total score. Statistical analysis: Mixed model for repeated measures with covariates baseline BOSCC-total, chronological age and centre. Results Between July 2018 and October 2021, N 134 children with ASD were randomly allocated to intervention (A-FFIP: n 68, EIAU: n 66). Groups did not differ at baseline, with a mean age of 49 (SD 10) months, a mean developmental age of 23.3 (SD 13.6) months and 26 (19.4%) females. The SARS-CoV-2 pandemic interfered severely with trial procedures. Intention-to-treat analysis in the primary analysis set, with at least one postbaseline BOSCC measure (A-FFIP n 64, EIAU n 60), did not find differences in the primary outcome by group (adjusted ES 0.06, 95% CI to 0.24 to 0.11). SARS-CoV2-related lockdown led to less improvement across groups. Secondary outcomes showed stronger improvements in parent-rated repetitive behaviour as well as parent- and teacher-rated executive functions for A-FFIP versus EIAU. Adverse events were comparable between groups. Conclusions The manualised NDBI program A-FFIP, which allows individually targeting six core basic abilities and five developmental domains related to longitudinal development in ASD, did not improve social communication, cognitive or behavioural outcomes beyond EIAU after 1 year, but may improve repetitive behaviour and executive function.
