PSYDR I know you've bowed out, but it's early and I can't sleep so I'm spending time reading your citations 🙂 They're kind of dated, and I had trouble finding anything more recent. Though I admit I didn't really dig too hard. My overall impression of these articles is that while they find correlations, they tend to be small. Though the 2nd article had some higher numbers with the MMPI. I don't really think that they support any type of prediction of success in grad school. I also think that faculty who are interviewing potential students are likely to pick up on personality problems in an interview. Unless of course those faculty members already have personality problems of their own, and they are attracted to people like themselves 🙄
The Gough chapter is interesting, especially the differences between males and females in the number of correlates. On an aside, you have to love Google Books! 👍
- For women, the only correlation between time to complete PhD and the test battery variables yielded was the Pd scale on the MMPI with women scoring higher on psychopathic deviance taking longer to finish. r=.16 at p<.05, which is hardly an earth shattering finding.
- Men had 22 correlates, including on the MMPI the D, Pt, Sc and Welsch A. But again, all r values are less than .20. Pretty much all of the correlations are less than .20, except for "military leadership" on the adjective checklist (r=-.24).
- It should be noted that prestige of undergraduate college's correlation was significant and essentially the same size as the personality variables.
- The author basically concludes that there's nothing really important in the data, even after regression are used.
- They then discuss item analysis on the adjective checklist, which yields 21 items more commonly endorsed by students who finish their PhD faster. I like that handsome is in that list. 😀
- Same analysis yielded 9 items in people who take longer. One is "zany." That's awesome.
- They then put these items into a scale and get a correlation of .31 for both men and women. The author says that this scale is not meant to be used for predictive value.
- They do the same item analysis with the CPI and find 16 items that are correlated with taking longer. They make a scale and the correlations are larger this time (.37-.48).
- So then we get more complicated in a new study which has better methods, including the subject being described by others to offset self-report bias. Correlations with time to complete on the ACL were slightly higher .23 to .33, and the CPI correlations to time to complete were lower (.15 to .27).
- The study concludes that people who tend to be "noncompetitive, conflict-avoiding, nonconforming, imaginative, and less inclined to structure or manage their energies toward any one goal" tend to take longer to finish their PhD. People who are "foresighted and planful, good with self-management, organized, optimistic and self-satisfied with their talents" take less time.
My response to all of this is "well no sh-t?"
Now on to the article...
- Using the MMPI, strong interest blank, academic variables, etc. I do like that they coded letter's of recommendation. That's pretty interesting. Variables were obtained at multiple points in training and include supervisor, facutly, and peer ratings.
- The findings in this study are interesting. Having higher Pt and lower K were most likley to have higher internship evaluations on "knowledge of personality and counseling theory." The positive correlation between Pt and this rating seems to contradict the Gough chapter that cites having higher Pt is correlated with taking longer to finish in men. Grant it it's not the same variable, but still worthy of considering. Having higher scores on the Pd scale didn't bode so well in this area, which is more consistent with Gough.
- Having higher Sc scores was correlated with lower ratings of "knowledge of psychopathology" while lower K scores meant higher knowledge of psychopathology. And my personal favorite...higher scores on the Paranoia scale were correlated with higher ratings of responsibility and therapeutic relationship skills! 😀
- People with higher introversion scores made the best use of supervision on internship.
- People with "dynamic" LOR's from undergradute profs were more likely to receive higher ratings on "motivation" on internship.
- Only "endorsement strength" on the LOR was correlated with any practicum ratings.
- Faculty and peer ratings were correlated with "overall endorsement strength" on the LORs and "quality of undergrad institution."
- No MMPI variables were significantly related to comprehensive exam performance measures.
- The authors in their discussion state that the most interesting finding out of all of the variables they looked at was the correlation between personality variables on the MMPI and ratings on internship, which reflect how grad students operate in the real world of psychological practice.
So what I take from this article is that certain MMPI scores will predict how well a student functions on internship. There is no relationship to other performance measures throughout graduate training (i.e. practicum evals, comp. exams). So personality does not predict how well we will do in school or even in early clinical experience, but once we finish and are put into a 40 (or more) hour per week clinical job. Students can make it all the way to internship without a problem. Grant it this study was done in the 80's when there wasn't this imbalance in internship slots to students we have today. So maybe it wasn't as tough to match.
From my personal experience as an intern, this is the toughest year because you are outside of the grad school bubble, and are expected to bring everything together, be a relatively competent clinician, and act like a peer to people who are already practicing. Quite honestly it's exhausting, and "intern burn-out" seems to set in relatively early from what I can tell in talking with peers. I would suspect that those with some weak points in their personality would be more likely to show those at this level in training, where they may keep things under control while taking courses or on a part time practicum placement.
This post is already way too long. Thanks for reading whoever made it this far 😀
