This book by S. R. Slavson, eminent for his work in group psychotherapy with both adults and children, and Mortimer Schiffer, a practitioner of group psychotherapy with children, was published too recently to be reviewed in this issue. However, it should be pointed out that the authors distill “experiences of four decades with many thousands of children in a great number of groups of different modalities and in different situations.” The book contains separate sections on activity group therapy, activity-interview group psychotherapy, playgroup therapy, and the therapeutic play group—each with protocols and case histories. A review will appear in the next issue of this journal.
