Abstract

The purposes of the present study were to detect personality differences between and to predict group membership of long-term users, short-term users, and nonusers of Lysergic Acid Diethylamide (LSD). A questionnaire was used to identify drug users and match them with a control group. The Sixteen Personality Factor Questionnaire (16PF) and the Inner-Directedness (I-D) and Time-Competence (T-C) Scales of the Personality Orientation Inventory (POI) were used to measure personality differences and to make predictions about group membership. The results were obtained through the use of discriminant analysis. Six factors of the 16PF were found significant. On factor B, long-term users and short-term users scored significantly higher than nonusers. On factor Q3, long-term users scored significantly lower than short-term users and nonusers. On factor E, short-term users scored significantly higher, and on factor A, significantly lower, than long-term users and nonusers. On factor Q2, nonusers scored significantly higher, and on factor O, significantly lower, than either user group. On the POI, all three groups were found to be time-incompetent. Results and weaknesses of the present study are compared with previous studies.
