Based on 143 children, the ASD group (n = 68) showed significantly higher ADOS-2 item and algorithm total scores as well as social affect and repetitive and restricted behaviors domain scores compared with children with nonspectrum (NS; n = 42) disorders and typically developing (TD; n = 33) children. Using lower algorithm cutoffs, sensitivities were excellent for the ASD versus NS/TD comparisons, ranging from 94% to 100% across different Modules. Specificities varied more, ranging from 82% to 100%. Internal consistency was strong with high item-total correlations (r of 0.6-0.9) and Cronbach's Alphas (all above 0.7). Results demonstrated promising, initial evidence for the validity of the ADOS-2 for South Korean toddlers and preschoolers from 1 to 4 years of age. The ADOS-2 could be implemented, with minimal adaptations, in research and clinical settings in South Korea.

Short caregiver interview and play observation for early screening of autism spectrum disorder: Behavior development screening for toddlers (BeDevel) / Guiyoung BONG in Autism Research, 14-7 (July 2021)

The data of 431 toddlers (male 66.2%; mean age (SD) = 29.11 (8.59) months; ASD, n = 201; developmental delay, n = 46; typically developing, n = 184), aged 18?~?42?months, were included in the validation of BeDevel. The best clinical estimate diagnosis, screening rate, validity, sensitivity, and reliability of BeDevel were determined based on data cross-sectionally collected using BeDevel and existing diagnostic/screening instruments: autism diagnostic observation schedule (ADOS), autism diagnostic interview (ADI-R), Vineland adaptive behavior scales-II (VABS-II), social response scales (SRS), sequenced language scale for infants (SELSI), Korean childhood autism rating scale (K-CARS), and Korean social communication questionnaire (K-SCQ). The k values of BeDevel-I and BeDevel-P were 0.055?~?0.732 and 0.291?~?0.752, respectively. Items related to social referencing in BeDevel-P had a particularly high diagnostic validity (k = 0.483?~?0.684). Reliabilities of BeDevel-I and BeDevel-P were sufficient (Cronbach's alpha = 0.86?~?0.88 and 0.92?~?0.95, respectively). BeDevel-I and BeDevel-P showed high sensitivity (BeDevel-I: 85.00?~?89.29%; BeDevel-P: 85.00?~?91.75%), specificity (BeDevel-I: 77.55?~?89.55%; BeDevel-P: 85.09?~?97.01%), PPV (BeDevel-I: 70.83?~?88.54%; BeDevel-P: 81.52?~?94.68%), and NPV (BeDevel-I: 76.00?~?95.24%; BeDevel-P: 84.62?~?95.45%). The agreement between the composite BeDevel score and ADOS, ADI-R, K-CARS, and K-SCQ was >67.6% (range = 67.6?~?90.8%). Combining a short caregiver interview and direct play observation is a valid and reliable screening process. More studies on social referencing as an important early marker are needed. BeDevel can be utilized as a secondary screening instrument before diagnostic confirmation in clinical and community settings. LAY SUMMARY: BeDevel, which consists of a short caregiver interview and direct play observation, is a valid and reliable screening instrument for autism spectrum disorder (ASD). We suggest that BeDevel can be utilized as a secondary instrument before administering diagnostic assessments in clinical and community settings. More studies examining social referencing as a potential behavioral marker of ASD are needed.

The Feasibility and Validity of Autism Spectrum Disorder Screening Instrument: Behavior Development Screening for Toddlers (BeDevel)-A Pilot Study / Guiyoung BONG in Autism Research, 12-7 (July 2019)

Limitations of existing screening instruments, and the need for a culturally appropriate early screening tool in Korean children, led us to develop Behavior Development Screening for Toddlers (BeDevel). The BeDevel assessment consists of two parts: BeDevel-Interview, a structured interview measure for parents/primary caregivers; and BeDevel-Play, a play-based semi-structured observational measure in children. To examine the feasibility and validity of BeDevel, 155 children (N = 75 ASD, N = 55 typical development, N = 25 developmentally delayed) aged 18-42 months (M = 31.54 months, SD = 7.60) were examined through parent-reported screening questionnaires, BeDevel, and standard diagnostic assessments. When BeDevel items were analyzed using Cohen's kappa statistics, most items in BeDevel-Interview and all items in BeDevel-Play were reasonably consistent with diagnoses. We identified primary items, which were significantly interacted with actual diagnosis in the chi-squared test (P < 0.05, range = 0.000-0.032). Using cutoff numbers of items determined using the receiver operating characteristics curve, BeDevel showed satisfactory levels of sensitivity (83.33%-100%), specificity (81.25%-100%), positive predictive values (80.65%-100%), and negative predictive values (83.87%-100%), as well as high internal consistency (Cronbach's alpha = 0.866-959). The agreement between BeDevel and most other screening/diagnostic instruments was moderate (k = 0.419-1.000). These results suggest that BeDevel can be a useful instrument for early screening of ASD.

When individual items were analyzed, responses of all BeDevel-Interview items and of most BeDevel-Play items well matched actual diagnoses, and we identified primary items, which were particularly useful in differentiating between the ASD group and the non-ASD group. With the optimal screening criteria determined, the BeDevel was able to identify individuals with a diagnosis of ASD and those without it, all at satisfactory levels. Lastly, BeDevel items were closely related as a set, and the BeDevel screening results were reasonably consistent with the results of most other screening/diagnostic instruments. These results suggest that BeDevel can be a useful instrument for early screening of ASD.
