Background:
The Scale of Emotional Development - Short (SED-S) captures the level of emotional development in persons with a disorder of intellectual development (DID) with 200 items on five developmental levels. The study aims to develop a brief version of the SED-S.
Methods:
Based on item analysis (proportions, χ2 -test, Spearman's ρ and corrected item-total correlation), a brief version of the SED-S was developed in a sample of 224 adults with a DID (n1 ) and validated in a second independent matched sample (n2 = 223).
Results:
Item reliability ranged per item set from Cronbach's α = 0.835 to 0.924. Weighted kappa resulted in κω = 0.743 (P < 0.001, 95% confidence interval = 0.690-0.802). Overall agreement of the brief version with the original SED-S was PO = 0.7. The brief version of the SED-S showed weaknesses in distinguishing level 2 from the adjacent levels.
Conclusions:
The brief version of the SED-S showed good reliability and moderate to good validity results. Items of phase 2 and, to some degree, of phase 5 should be revised to further improve the psychometric properties of the scale.
