This paper reports a pilot study comparing the MMPI scores for a group of 12 male suicide attempters with a group of 12 male drug abusers who were drawn from consecutive admissions to the New Hampshire Hospital. The purpose of the study was to determine whether or not there was any relationship among the personality characteristics between the 2 groups. The mean T score profiles for both groups on the MMPI were found to correlate significantly (P<.05) with each other.
