Validation of the Differential Emotions Scale in 613 mothers

Mothers (N=613) with infants who took the Differential Emotions Scale (DES) were compared in a cross-validation study by factor analysis to 957 high school and college students. Despite differences in factor-analytic technique, similarities in factor structure suggested that the DES discriminates the majority of fundamental emotions as posited by Izard.Robert Emde is supported by Research Scientists Award No. 5 KO5 MH 36808 and NIMH Project Grant No. 2 RO1 MH 22803.
