Since I was studying the same constructs that were mentioned in the DSM-IV, I chose to use the theoretical strategy approach to test construction (Belchier 2005). All questions were formulated so that each one would address an important construct used to diagnose BPD. Each item was scored according to the number circled. A response of 1 equaled 1 point; 2 equaled 2 points; etc. A score of 36-50 indicated borderline personality disorder. A score between 21 and 35 indicated that there may be some traits consistent with BPD, but there was not enough evidence to say whether the disorder truly exists. A score of 20 or less indicated that the person does not have BPD. Results Every number marked was tallied, and the total score for each participant was written on the bottom of their copy of their printed out questionnaire. Then all the totals were lined up in numeric order. The middle score, 34, was found to be the median. Then all the scores were added and divided by the sample size, 5, to find the mean of 31. The standard deviation, 9.95, was calculated by taking the square root of the average squared deviation from the mean. The scores ranged from 18 to 43, with the higher scores representing a greater degree of borderline personality. Two of the people tested had scores within the BPD range, two people scored in the middle range, and one person scored in the lowest range, showing no evidence of borderline personality disorder. One issue of concern with the data....
IX) Test administration will be explained in the Method section of the report.
X) The median score was 34. The mean score was 32.4. The standard deviation was 9.18. All five participants had college educations. All the participants were single, with no children.
Borderline Personality Disorder (BPD) is a relatively new and controversial clinical diagnosis. It is estimated that nearly 6 million people suffer from the disorder, and yet it is not widely discussed within the psychological community (Roth and Freidman 2003). Why the silence surrounding BPD Perhaps it is because there is no easy treatment. As Roth and Friedman so colourfully put it, "it's difficult to explain BPD in snappy headlines and sound bites to a restless audience wont to channel surf" (2003). So then, why even study BPD Surely, it is just some imaginary psychological problem created to make a certain group of people feel better about themselves. It is just an opportunity for weak-minded individuals to throw the blame for their own interpersonal problems onto someone else. Or is it
Mason and Kreger, in their ground-breaking 1998 book, explain borderline personality disorder in great detail. They list the DSM-IV criteria for classifying BPD, which include: "frantic efforts to avoid real of imagined abandonment a pattern of unstable and intense interpersonal relationships impulsivity self-damaging behavior suicidal thoughts affective instability [and] chronic feelings of emptiness" (Mason and Kreger 1998). On her web site, Deb Martinson (2002) lists some of these constructs, and it is her list that forms the basis of the present questionnaire. Specifically, the constructs I seek to analyse in this study are:
