Mental health literacy as theory: current challenges and future directions

Abstract

Background: Mental health literacy (MHL) is one increasingly researched factor thought to influence mental health behaviors. Researchers have argued for expanding the definition of MHL to include additional constructs, but no consensus has yet been reached on what constructs should be included as part of MHL.

Aims: The purpose of this paper is to (i) elucidate how the expansion of the MHL construct has impeded the growth of MHL research and (ii) through the lens of construct and theory development, highlight how these challenges might be remedied.

Methods: An inclusive search of the literature was undertaken to identify MHL studies. The principles of construct and theory development guided a critical analysis of MHL.

Results: The review of the literature found that MHL violates many principles of what constitutes an acceptable construct definition. To address these concerns, we proposed conceptualizing MHL as a theory and recommended principles of theory development that should be taken into consideration.

Conclusion: A theory of MHL can guide future researchers to clearly delineate important constructs and their interrelationships. For practitioners, a theory of MHL can help inform how to improve MHL at both the individual and community level.
