Testing Mediators and Moderators of a Fotonovela for Depression to Promote Help-seeking Behavior

Latinx adults with depression are a particularly vulnerable population; although Latinx exhibit similar rates of depression to other racial/ethnic groups, they are less likely to seek treatment, are more likely to drop out of treatment, and thus experience greater chronicity of depression. This health disparity is likely due to a complex network of factors, but mental health literacy is one important contributing factor. Latinx are more likely to exhibit lower mental health literacy (including misconceptions, stigma, knowledge of treatment, etc.), which contributes to lower rates of treatment-seeking. Understanding how to engage Latinx in depression treatment by overcoming health literacy barriers is important in reducing health disparities.

Entertainment-education interventions are those that use popular media to engage consumers and deliver health messages. These interventions hypothesized to be useful in targeting populations with health disparities in encouraging changes in health-related behavior through dramatic and culturally-relevant narrative elements. However, no study has tested these theorized mechanisms in helping to explain changes in health literacy and subsequent health behavior.

This study will test the impact of a graphic novel about depression specifically for Latinx adults with depressive symptoms on theorized mediators, including transportation (feeling emotionally engaged in the narrative), identification (cultural relevance of characters, their language, and their appearance), and social proliferation (sharing of health information and mutual reinforcement of health behaviors). Furthermore, this study will test if these mediators help explain changes in mental health literacy and subsequent health behavior. Lastly, this study will test moderators of changes in mental health literacy and behavior to determine for whom the fotonovela has the largest impact.
