The data of 431 toddlers (male 66.2%; mean age (\n                      <jats:italic>SD<\/jats:italic>\n                      ) = 29.11 (8.59) months; ASD,\n                      <jats:italic>n<\/jats:italic>\n                      = 201; developmental delay,\n                      <jats:italic>n<\/jats:italic>\n                      = 46; typically developing,\n                      <jats:italic>n<\/jats:italic>\n                      = 184), aged 18\u2009~\u200942\u2009months, 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\u2010sectionally collected using BeDevel and existing diagnostic\/screening instruments: autism diagnostic observation schedule (ADOS), autism diagnostic interview (ADI\u2010R), Vineland adaptive behavior scales\u2010II (VABS\u2010II), social response scales (SRS), sequenced language scale for infants (SELSI), Korean childhood autism rating scale (K\u2010CARS), and Korean social communication questionnaire (K\u2010SCQ). The\n                      <jats:italic>k<\/jats:italic>\n                      values of BeDevel\u2010I and BeDevel\u2010P were 0.055\u2009~\u20090.732 and 0.291\u2009~\u20090.752, respectively. Items related to social referencing in BeDevel\u2010P had a particularly high diagnostic validity (\n                      <jats:italic>k<\/jats:italic>\n                      = 0.483\u2009~\u20090.684). Reliabilities of BeDevel\u2010I and BeDevel\u2010P were sufficient (Cronbach's alpha = 0.86\u2009~\u20090.88 and 0.92\u2009~\u20090.95, respectively). BeDevel\u2010I and BeDevel\u2010P showed high sensitivity (BeDevel\u2010I: 85.00\u2009~\u200989.29%; BeDevel\u2010P: 85.00\u2009~\u200991.75%), specificity (BeDevel\u2010I: 77.55\u2009~\u200989.55%; BeDevel\u2010P: 85.09\u2009~\u200997.01%), PPV (BeDevel\u2010I: 70.83\u2009~\u200988.54%; BeDevel\u2010P: 81.52\u2009~\u200994.68%), and NPV (BeDevel\u2010I: 76.00\u2009~\u200995.24%; BeDevel\u2010P: 84.62\u2009~\u200995.45%). The agreement between the composite BeDevel score and ADOS, ADI\u2010R, K\u2010CARS, and K\u2010SCQ was &gt;67.6% (range = 67.6\u2009~\u200990.8%). 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.\n                    <\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Lay summary<\/jats:title>\n                    <jats:p>BeDevel, which consists of a short caregiver interview and direct play observation, is a valid and reliable screening instrument for autism spectrum disorder (ASD).
