This paper will examine the results of four studies one is a prospective follow-up study, one is a prospective naturalistic study, one is a case control study and the last one is a randomized clinical trial. They are on borderline personality disorder and substance abuse articles by Walter et al. (2009), Zanarini et al. (2010), Gratz & Tull, (2010), and by Linehan, Schmidt III, Dimeff, Craft, Kanter & Comtois, (1999) respectively. The hypotheses, methods and results will be summarized. The future research areas suggested by Walter et al. (2009), Zanarini et al (2010), Gratz & Tull, (2010), and by Linehan et al. (1999) will be discussed along with the value of their studies to the field of psychiatric rehabilitation.
In conducting their study, Walter et al. (2009) examined the risk level of substance use disorders (SUDs) between people who have borderline personality disorder (BPD) and those who had other personality disorders (OPD). They also examined the risk of new onset of SUD between individuals with BPD that is remitted versus non-remitted. The researcher’s hypothesized individuals with BPD would have an increased risk of SUD when compared to those in the OPD group.
Participants in the study were part of an ongoing Collaborative Longitudinal Personality Disorders Study. The OPD group combined Axis II diagnosis’s of: schizotypal personality disorder (STPD), avoidant personality disorder (AVPD), and obsessive-compulsive disorder (OCPD), Identified are approximately 371 women and 200 men for a total of 571 participants. The participants who had BPD were placed I a group separate from those who had OPD. The BPD group had approximately 15% more men and women then the OPD group. The BPD group was subdivided into two groups remitted and non-remitted. All participants were interviewed at baseline using a “Structured Clinical interview for DSM-IV Axis I Disorders and the Diagnostic Interview for DSM-IV Personality Disorders (DIPD)”. They were reassessed at six and twelve months and every year for an additional six years afterwards with “the follow-along version of the DIPD and the Longitudinal Interval Follow-up Evaluation (LIFE)”. (Walter et al. 2009)
The results of the article by Walter et al. (2009) supported the hypothesis, indicating that people with BPD have a higher rate of SUD as well as alcohol and drug dependency. The rate of new onset of alcohol use disorder and new onset of drug use disorder was 7% higher in the BPD group when compared to the OPD group. After 24 months of follow-up approximately half of the people who had BPD showed stable remission of diagnosis. In addition, at baseline, the people who were remitted with BPD had 57% higher frequency of drug use disorder and 42% higher alcohol use disorder. The rate of new onset of SUD was 11% higher in the non-remitted groups. The results support the hypothesis in which people with BPD have increased rates and severity of SUD when compared to the OPD...
