title: Processes of inference, schizotypal thinking, and obsessive-compulsive behaviour in a normal sample.
abstract: Previous research has shown inferential confusion as measured by the Inferential Confusion Questionnaire to be related to obsessive-compulsive symptoms. A total of 108 participants (41 men and 66 women) from a normal population in The Netherlands (M age = 46 yr., SD = 15.5) completed a package of questionnaires measuring inferential confusion, schizotypal symptoms, and obsessive-compulsive behaviour. As expected, scores for both inferential confusion and schizotypal symptoms were significantly related to those for obsessive-compulsive behaviour. In addition, analysis showed that inferential confusion and schizotypal symptoms shared common variance, but both predicted an independent portion of the variance in obsessive-compulsive behaviour while controlling for neuroticism. The present results call for further inquiry into the role of inferential confusion and schizotypal thinking in obsessive-compulsive behaviour.
