The usefulness of dipropyltryptamine (DPT) as an adjunct to psychedelic therapy was explored in a pilot study carried out on 51 alcoholic patients from the Alcoholic Rehabilitation Unit at Spring Grove State Hospital. The evaluation of the results was based on the comparison of pre- and posttreatment results of a battery of psychological tests and of pretreatment and follow-up ratings of an independent team of social workers. The psychological tests involved the Minnesota multiphasic personality inventory (MMPI), Personal orientation inventory (POI), Raven progressive matrices, Psychiatric evaluation profile (PEP), and Benton visual retention test. The social history questionnaire used by the social workers for assessment of the patients’ adjustment consisted of 0-10-point scales measuring residential, occupational and interpersonal adjustment, abstinence, and global adjustment.
