The use of the Self-Description Questionnaire (SDQ), in its various fo
rm, is recommended for use with gifted students, yet little psychometr
ic data exist with respect to the use of these subscales with this pop
ulation. The SDQ-II was administered to adolescents attending a summer
residential program for academically gifted students (N = 459). Estim
ates of internal consistency for scores on the 11 subscales are large
enough to warrant group interpretation and research uses (mean alpha =
.89) and possibly individual uses for older gifted students. Confirma
tory factor analysis provides limited evidence of construct validity u
sing data from this sample of gifted students. The relatively poor fit
of the tested models may be due to the extreme negative skewness of i
tem score distributions.
