How do education and experience with mental illness interact with causal beliefs, eligible treatments and stigmatising attitudes towards schizophrenia? A comparison between mental health professionals, psychology students, relatives and patients

Background: The main purpose of this study was to investigate the perception of schizophrenia in different categories of persons (directly and/or indirectly) involved with it. Hypotheses were made concerning the definition of a multi-class structure where each class should identify a profile characteristic of each respondent's specific role, (e.g.: mental health professional, relative, patient, and student) and specific indicators of schizophrenia (e.g.: causal beliefs, eligible treatments, social distance, perceived dangerousness and public avoidance). Methods: This study involved 577 participants all in contact with schizophrenia with different roles. A Latent Class Analysis (LCA) was applied to define a latent structure of schizophrenia aspects. Such structure was expected be affected by the interaction between respondents' roles, as external variable, and schizophrenia indicators as manifest variables. Results: A four-latent-class structure representing the four respondents' roles was evidenced, further each class was characterized by schizophrenia indicators representing a profile for each role. Analogies and differences of views and preferences of the respondents' roles concerning schizophrenia emerged clearly. Conclusions: The four groups of people involved with schizophrenia with different roles demonstrated to interact significantly with specific indicators of schizophrenia shedding new lights on the understanding of schizophrenia in its complexity.
