How to measure knowledge about mental disorders:validation of the Italian version of the MAKS

The aim of this study is to validate the Italian version of the Mental Health Knowledge Schedule (MAKS-I). The validation process included: linguistic validation; analysis of the feasibility; face validity; internal consistency; floor and the ceiling effects; divergent validity. Multiple linear regression was performed to examine the relationship between mental health knowledge and independent variables. MAKS-I was administered to 453 people. The linguistic validation was successful and face validity of the questionnaire showed no critical issues. The estimated composite reliability was 0.638. Divergent validity was supported by lack of statistical significant correlation between MAKS-I and RIBS-I with a positive correlation index. Participation in seminars or conferences related to the issue of mental health stigma, gender, qualification and having a first or second-degree relatives with a psychiatric disorder can be considered possible predictors of the MAKS-I score. MAKS-I is a reliable questionnaire to assess mental health knowledge and familiarity with psychiatric clinical conditions in Italian language.
