After a brief discussion of the difficulties involved in the diagnosis and prognosis of emotional disturbances in adolescents and the intense repression and resistance found during this period, the author presents the case of a seventeen-year-old boy who entered treatment because of fatigability, fear of blushing and perspiring, timidity, and inhibition in his social relationships. The patient's defenses were similar to those found in the latency period; there was a tendency to identify with the therapist and to deny by use of daydreams and fantasies. Henny concludes that in emotionally disturbed adolescents there appears to be a blurring of the sense of reality which may give the impression of psychotic functioning and which requires careful handling.
