The authors examine data on dream frequency from 50 patients, half of whom were seen in psychoanalysis and half in psychoanalytic psychotherapy. Frequency, defined as the proportion of sessions where at least one dream is related, is analyzed statistically as a function of sex, age, and type of treatment. Also, treatment outcome is examined as a function of sex, type of treatment, diagnosis, and dream frequency. Psychoanalytic patients are found to have higher dream frequency than the patients in the psychotherapy group. Higher average dream frequency is correlated with a better treatment outcome in both patient groups.
