The role of income and emotional engagement in the efficacy of a brief help-seeking video intervention for essential workers

Background Recently we showed that a brief video-based intervention can improve openness to help-seeking and decrease treatment-related stigma among essential workers, particularly for female and Black individuals viewing demographically matched protagonists. The current randomized controlled trial explored two additional factors which may enhance the efficacy of this intervention: income level, known to be associated with help-seeking, and emotional engagement, which may enhance a person's ability to engage with the intervention. We hypothesized that income level and emotional engagement would correlate with changes in openness to help-seeking (“openness”) and stigma. Methods Essential workers (N = 1405) randomly viewed a control video or a brief video of an actor portraying an essential worker describing COVID-19-related anxiety and depression and treatment benefits. Openness and stigma were assessed at baseline, post-intervention, and 30-day follow-up, with emotional engagement assessed post-intervention. Results The brief video intervention demonstrated immediate increases in openness (p < 0.001, Cohen's d = 0.39) and decreases in stigma (p < 0.001, d = 0.14) compared to the control. Reported income level affected neither dependent variable. Participants who scored higher on the emotional engagement scale reported greater change in openness and stigma. Limitations Use of a crowdsourcing platform may limit generalizability. Conclusions The 3-min video showed modest effect sizes for immediate increased openness and reduced stigma, with greater emotional engagement heightening the effect, suggesting a possible mediator to the intervention. Income level did not affect intervention outcomes. Research should explore the role of income by adding income-related content to the brief-video interventions and assessing whether links to referrals could foster immediate behavioral change.
