Abstract
"It may in conclusion be observed that the comparison of problem children with normals . . . affords a modicum of validation for the Children's Form of the Picture-Frustration Study; i.e., the differences between the two populations are, in general, consistent with what one might expect from the fact that the problem children have 'problems' and are, therefore, presumably more frustrated."
