Screening for BPD in out-patient youth is feasible but is not a replacement for clinical diagnosis.
The aim of the study was to develop a self-report measure that assesses borderline personality traits as defined by DSM-IV criteria, including separate subscales for each criterion. A sample of normal subjects from community colleges in the midwestern region of the United States was used to develop the scale. The psychometric properties of the scale were examined using an additional United States sample and student samples from England and Australia. The scale was compared with existing measures of borderline and schizotypal personality. Evidence for the internal consistency and convergent and divergent validity of the new scale is presented. The results of several analyses of variance comparing males and females in the three national groups are reported. A Principal Components Analysis of the subscales suggested either a single factor or two correlated factors. Oblique rotation yielded a structure that distinguished identity/interpersonal and impulsivity borderline personality traits. It is concluded that the new scale provides a useful tool for clinicians and researchers interested in screening for borderline personality traits in both general and clinical populations. Suggestions for further research are indicated.
Student subjects completed an updated version of Litle and Zuckerman's Music Preference Scale, a questionnaire measuring musical preference. They also completed the NEO Personality Inventory (Revised), a measure of the Five-Factor Model of personality. Factor analysis identified three patterns of preference associated with liking for most types of Rock Music, general Breadth of Musical Preference, and liking for Popular Music (such as easy listening). The three factors were employed as dependent variables in canonical correlations to examine relationships with personality. As predicted, most relationships with music preference involved the personality measures extraversion and openness. Extraverts obtained high scores on the Popular Music factor. Open individuals liked a wide range of music types. It was also found that females liked popular music styles more than did males. Particular personality "facets" were examined, as were the effects of musical training and interest. The research extends previous investigations relating preference and personality.
These findings indicate that "positive" schizotypy is associated with central features of "flow"-type experience, including distinct shift in phenomenological experience, deep absorption, focus on present experience, and sense of pleasure. The neurologically based construct of latent inhibition may be a mechanism that facilitates entry into flow-type states for schizotypal individuals. This may occur by reduced latent inhibition providing a "fresh" awareness and therefore a greater absorption in present experience, thus leading to flow-type states.
Everyone has their own unique version of the visual world and there has been growing interest in understanding the way that personality shapes one’s perception. Here, we investigated meaningful visual experiences in relation to the personality dimension of schizotypy. In a novel approach to this issue, a non-clinical sample of subjects (total n = 197) were presented with calibrated images of scenes, cartoons and faces of varying visibility embedded in noise; the spatial properties of the images were constructed to mimic the natural statistics of the environment. In two experiments, subjects were required to indicate what they saw in a large number of unique images, both with and without actual meaningful structure. The first experiment employed an open-ended response paradigm and used a variety of different images in noise; the second experiment only presented a series of faces embedded in noise, and required a forced-choice response from the subjects. The results in all conditions indicated that a high positive schizotypy score was associated with an increased tendency to perceive complex meaning in images comprised purely of random visual noise. Individuals high in positive schizotypy seemed to be employing a looser criterion (response bias) to determine what constituted a ‘meaningful’ image, while also being significantly less sensitive at the task than those low in positive schizotypy. Our results suggest that differences in perceptual performance for individuals high in positive schizotypy are not related to increased suggestibility or susceptibility to instruction, as had previously been suggested. Instead, the observed reductions in sensitivity along with increased response bias toward seeing something that is not there, indirectly implicated subtle neurophysiological differences associated with the personality dimension of schizotypy, that are theoretically pertinent to the continuum of schizophrenia and hallucination-proneness.
