The relationship of personality disorders (PDs) with self-esteem, locus of
control, and the interpersonal (dominance and love) and five-factor models
(neuroticism, extraversion, openness to experience, conscientiousness, and
agreeableness) of personality was investigated using 244 university student
s. Self-esteem and locus of control were good predictors for seven of the I
I personality disorders, indicating that these variables are useful additio
ns to the interpersonal and five-factor conceptions of PD. Self-esteem was
a strong predictor of the avoidant, borderline, dependent, and obsessive-co
mpulsive PDs. Most of the PDs are positively related to chance and powerful
others control and negatively related to internal locus of control. These
results suggest a possible continuum from interpersonal (antisocial) to int
rapsychic conflict (borderline), with the remaining disorders being mixture
s of these two extremes. This differing composition of interpersonal and ps
ychosocial variables is helpful in discriminating personality disorders.
