Relationship Between Tridimensional Personality Questionnaire Scores and Clinic Attendance Among Cocaine Abusing,Buprenorphine Maintained Outpatients

With the recent approval of buprenorphine for the treatment of opiate dependence in the United States it has become important to develop an understanding of the factors that influence the likelihood of successful treatment outcomes when using buprenorphine. This study examined, in a convenience sample, the relationship between novelty-seeking behaviors, as determined by Cloninger's Tridimensional Personality Questionnaire (TPQ), and attendance variables during participation in a buprenorphine-based treatment program for 21 heroin-dependent cocaine users that took place in the late 1990s. Approximately two-thirds of the participants were male and primarily African-American. About half of them were employed and had at least a high school education. Approximately one-third of them were married or cohabitating and they all resided in the greater Detroit, Michigan area of the United States. The Tridimensional Personality Questionnaire (TPQ) was administered to the participants prior to entering the treatment program. Demographic variables, psychiatric distress, and substance use severity were also evaluated. Variables with significant bivariate relationships with poor attendance measures were entered into a regression analysis predicting attendance measures. Participants who scored high on the TPQ Novelty Seeking Scale attended significantly fewer regularly scheduled visits, had a greater overall number of missed visits, and shorter treatment retention times. Demographics, substance use severity, and psychiatric distress did not have significant relationships with these attendance measures.
