It is contended that the Rorschach method is successful in analyzing the personality of children, that it permits an understanding of their "private worlds" and offers an insight into the underlying mechanisms of personality. In child deviates, it suggests therapeutic approaches; it gauges the effectiveness of treatment and the extent of recovery. In short, it works. Despite the subjectivity of the scoring, the sparsity of the norms, the reliance on clinical validation, the interpretation in terms of results from adult or psychiatric material, the method, from the pragmatic point of view, is valid for use with normal children. Because of such clinical and pragmatic evidence, it is justifiable perhaps to apply the Rorschach method in the clinical field, for there all methods and procedures available to the clinician, including the interview and personal and subjective judgments, are put to service. There can be no doubt that the Rorschach method in individual diagnosis of children can yield important information. But if the method is to be used as an instrument of research in studies of children, it must be established scientifically as a valid instrument. Thus the problem of the extent to which Rorschach results are valid for the normal child is of importance. In the present state of development, many results are inconclusive and invalid, and conclusions for younger children, especially, are of doubtful value. Results cannot be accepted as anything but tentative where the number of cases is small, the technique is not described, sexes are not differentiated, groups are casually compared, controls are not used, and standards of scoring and norms which are based on adult or psychiatric groups are applied. To be serviceable as an instrument of research, results must meet scientific requirements. Thus it may be said that studies based on the Rorschach method in the field of the normal child have been valuable in suggesting promising hypotheses and in pointing the... [ABSTRACT FROM AUTHOR]
