Measurement properties of the Mental Health Literacy Scale (MHLS) validation studies: a systematic review protocol

Area of Science:

• Mental Health Research
• Psychometrics
• Health Services Research

Background:

• Mental Health Literacy (MHL) is crucial for enhancing mental well-being and reducing treatment disparities.
• The Mental Health Literacy Scale (MHLS) is a validated instrument for assessing MHL.
• Understanding the MHLS's measurement properties across diverse linguistic and cultural contexts is essential for its appropriate application.

Purpose of the Study:

• To systematically review and compare the measurement properties of the MHLS in various languages.
• To provide evidence-based guidance for academics, clinicians, and policymakers on the use of the MHLS.
• To identify gaps in the literature regarding the MHLS's psychometric validation.

Main Methods:

• Adherence to COSMIN methodology and JBI Manual for Evidence Synthesis.
• Systematic literature search across multiple databases (PubMed, PsycINFO, CINAHL, Scopus, MEDLINE, Embase, ERIC) from May 2015 to December 2023.
• Methodological quality assessment using the COSMIN Risk of Bias checklist and comprehensive data synthesis.

Main Results:

• This section is to be populated upon completion of the review.
• Anticipated results will detail the psychometric performance of the MHLS across different language versions.
• The review will highlight variations in reliability and validity based on linguistic adaptation and population.

Conclusions:

• This systematic review will offer a critical evaluation of the MHLS's measurement properties.
• Findings will inform the selection and adaptation of the MHLS for diverse populations and research settings.
• The study aims to enhance the global utility and application of the MHLS in mental health research and practice.
