The reliability and validity of the Greenspan Social Emotional Growth Chart (GSEGC) in Israeli children with developmental delay and autism-A pilot study

Healthy social-emotional development in early childhood is important as an indicator of general well-being and for positive outcome in later childhood. Therefore, screening for potential social emotional problems is valuable. Accurate, usable, and affordable screening tools have been especially difficult to develop. The cross cultural validity of a screening instrument should be assessed. The aim of the current study was to investigate the reliability and validity of the Greenspan social-emotional growth chart (GSEGC) in Israeli children of three diagnostic groups: (1) Autistic spectrum disorder (ASD) (2) Developmental language disorder (DLD) and (3) Developmental motor delay (DMD). An internal reliability of alpha of 0.95 for the GSEGC standardized for age score and of 0.78 for the sensory processing sub scores was found. A confirmatory factor analysis (CFA) using a 5-factor model confirmed an acceptable fit. Positive (62.86%) and negative (94.73%) predictive values also support the clinical usefulness of the GSEGC in identifying children at low risk for ASD. Conclusions:The GSEGC appears to be a promising tool for the screening of social emotional problems in early childhood. Further studies in different cultures are warranted.
