Personality Characteristics of Volunteers for Medical Research
Abstract
Thirty-seven inmates who had previously volunteered for phase I drug testing and 33 who had not were interviewed by a psychologist to obtain demographic and motivational data. Each inmate completed a standard psychopathology inventory (the Minnesota Multiphasic Personality Inventory), the Similarities and Picture Arrangement subtests of the Wechsler Adult Intelligence Scale, a test of normal personality variables (the Edwards Personality Scale), and Christie's Machiavellianism Scale. The data supported the conclusions that (1) inmates are in general free enough from psychopathology to be able to make rational choices about participating in medical research as long as preliminary screening for individuals with severely disordered thinking is carried out, (2) verbal communication skills of inmates appear to be well enough developed to allow them to give an informed consent, (3) while there are personality differences between volunteers and nonvolunteers, these appear to relate most directly to the fact that, without screening, impulsive, manipulative individuals with disordered thought processes are over-represented among volunteers for medical research.

Volunteer bias is the tendency for well-adjusted, open, and compliant people to participate in studies, a function of personality.
“For instance, volunteer bias, a form of selection bias, is the tendency for well-adjusted, open, and compliant people to participate in studies [261], a function of personality [263, 264].”

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
