RESUMO
The aim of the present validation study is to determine the psychometric properties of the Slovenian version of the Mental Health Literacy Scale. For this purpose, the factorial structure, internal consistency, cross-cultural, convergent and discriminant validity were assessed. The measure was translated and adapted to Slovenian context through a blind back-translation process. It was applied to a representative sample of the Slovenian adult population via an online research panel. A total of 1189 participants (598 women), aged between 18 and 95 years (M = 46.7, SD = 16.2) completed the survey. Confirmatory and exploratory factor analyses, reliability analyses, hypothesis testing, and correlational analyses were conducted. The analyses rejected a hypothesised unidimensional model and demonstrated that a four-factor model with 27 items was the most theoretically and psychometrically adequate. The Slovenian version of Mental Health Literacy Scale (S-MHLS) consists of the following factors: (1) Attitudes Towards People With Mental Health Problems, (2) General Attitudes Towards Mental Health Problems and Help-Seeking, (3) Recognition of Mental Health Disorders and (4) Knowledge About Seeking Mental Health Information. The factors have adequate construct validity and internal consistency, which is also adequate for the entire S-MHLS. However, a decreased scope of the content might result in an inadequate representation of the construct of mental health literacy. In addition, the psychometric interpretation of the MHLS varies widely in validation studies across different linguistic contexts. Therefore, we propose a further improvement of the instrument with a psychometrically and theoretically sound multifactorial structure that demonstrates strong cross-cultural validity.
