In the present study, we recruited a large sample (N = 595) of highly educated participants to assess which causal variables they considered as more important in the etiology of two diagnostically unlabeled cases of Psychiatric Disorders. The first clinical case described a patient with early schizophrenia whereas the second clinical case described a patient with conversion disorder. We aimed at ascertaining if participants' gender, field of study (scientific vs. humanistic), and personality traits influenced their causal beliefs. Based on the scores assigned to both the clinical cases, participants believed that current life stressors were the most important etiological variable and that adverse early experiences were not an important causal factor in anyone of the two clinical cases. Regardless of their field of study, women perceived the loss of a loved one as a relevant variable in the etiology of conversion disorder. Participants' beliefs about the etiology of early schizophrenia varied with their field of study. Compared to participants studying humanities, those studying scientific disciplines attributed more importance to organic causes and less importance to unconscious conflict and early traumatic experiences. Overall, the role of personality traits in influencing causal beliefs was negligible. Public education about the causes of psychopathology is necessary to optimize actual usage of mental health services and treatment choice for Psychiatric Disorders.
