Validity of the Korean Developmental Screening Test for very-low-birth-weight infants

Abstract

Purpose The importance of the neurodevelopmental outcomes of very-low-birth-weight (VLBW) infants has been emphasized as their mortality rate has markedly improved. This study aimed to assess the validity of the Korean Developmental Screening Test (K-DST), a developmental screening tool approved by the Korean Society of Pediatrics, for the timely diagnosis of neurodevelopmental delay in VLBW infants. Methods Subjects included VLBW infants enrolled in the Korean Neonatal Network database between January 2012 and December 2014. The collected data were analyzed for sensitivity, specificity, positive predictive value, and negative predictive value (NPV) in the K-DST compared to those in the Bayley Scales of Infant Development-II for VLBW infants. Results A total of 173 patients were enrolled. Their mean gestational age and mean birth weight were 27.5±2.8 weeks and 980.5±272.1 g, respectively. The frequency of failed psychomotor developmental index (PDI) <85 was similar to that in at least one domain of K-DST <1 standard deviation. Failure in more than one K-DST domain compared with a mental developmental index (MDI) <85 showed a sensitivity and NPV of 73.2% and 75.0%, respectively. Failure in more than one K-DST domain compared with PDI <85 showed a sensitivity and NPV of 60.3% and 71.6%, respectively. Each K-DST domain had a stronger correlation with predicting a failing MDI <85 than a failing PDI <85 ( P <0.05). Conclusion K-DST could be a useful screening tool for predicting mental developmental delay in VLBW infants and referring them for neurodevelopmental assessments.

Neurodevelopmental Correlations between the Korean Developmental Screening Test and Bayley Scale III in Very-Low-Birth-Weight Infants

“…However, Kim's results are consistent with ours. As shown in Our findings are inconsistent with those by Kim et al 25) , who analyzed the relationship between the K-DST and BSID-II. In the study by Kim et al 27) , the r-values for cognition, lan guage, and sociality were 0.498 (P<0.0001), 0.526 (P<0.0001), and 0.384 (P<0.0001), respectively.…”

“…According to the correlation analysis of the individual domains of the K-DST and BSID-II in VLBW infants by Kim et al 25) , four domains (fine motor, cognition, language, and sociality) were significantly associated with BSID-II MDI, but not BSID-II PDI, scores. This is the first study regarding the BSID-III and K-DST.…”

Preventive Intervention Program on the Outcomes of Very Preterm Infants and Caregivers: A Multicenter Randomized Controlled Trial

“…The K-DST is a parent-reported developmental screening questionnaire developed by the Korean Pediatric Society [ 15 ]. This questionnaire encompasses gross motor, fine motor, cognition, language, personal, social, and self-help domains.…”

Impact of very preterm birth and post-discharge growth on cardiometabolic outcomes at school age: a retrospective cohort study

“…Prematurity accounts for almost 10 % of births worldwide and 7.2 % of births in Korea with increasing tendency [ 1 , 2 ]. Despite improvements in the overall survival of preterm infants in recent decades [ 3 , 4 ], health inequalities emerge later in life in this population. Since the term “thrift phenomenon” was coined by Barker and colleagues [ 5 ], an association between low birth weight or small for gestational age (SGA) babies and cardiometabolic problems, such as insulin resistance and increased blood pressure (BP), has been consistently demonstrated by many prospective and cohort studies [ 6 – 8 ].…”
