title: Motivational predictors of psychometrically-defined schizotypy in a non-clinical sample: goal process representation, approach-avoid temperament, and aberrant salience.
abstract: Patterns of problematic volitional control in schizotypal personality disorder pertaining to goal process representation (GPR), approach and avoidance temperament, and aberrant salience have not been widely investigated in emerging adults. The present study aimed to provide preliminary evidence for the utility of examining these three motivational constructs as predictors of high versus low levels of psychometrically-defined schizotypy in a non-clinic sample. When college students with high levels of self-reported schizotypy (n = 88) were compared to those with low levels (n = 87) by means of logistic regression, aberrant salience, avoidant temperament, and the self-criticism component of GPR together accounted for 51% of the variance in schizotypy group assignment. Higher score on these three motivational dimensions reflected a proclivity toward higher levels of schizotypy. The current findings justify the continued exploration of goal-related constructs as useful motivational elements in psychopathology research.
