Mental health first aid training to improve depression literacy among health ambassadors in Iran: study protocol for a cluster-randomized controlled trial.
Article in Trials, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
BACKGROUND AND
objectiveOne of the strategies for enhancing the mental health literacy of the community could be capacity building in the field of mental health first aid (MHFA) training among health ambassadors, who serve as volunteers between health service providers and families. The present study aims to investigate the effectiveness of MHFA training packages for depression prevention using critical thinking methods on the depression literacy (as a key component of mental health literacy) of health ambassadors to assist in the early identification and timely referral of individuals with depressive disorders. Depressive disorders are among the most prevalent mental health conditions, yet many individuals delay or avoid seeking treatment due to stigma and limited awareness. Improving mental health literacy is therefore essential to promote early recognition and timely help-seeking. Health ambassadors, as community volunteers linking families to health services, are uniquely positioned to support this goal. This study applies a culturally adapted MHFA training package for depression, delivered through critical thinking and role playing, in improving the depression literacy (as a key component of mental health literacy) of health ambassadors. The trial seeks to determine whether this approach enhances their ability to recognize symptoms, provide initial support, and facilitate referral to professional care. METHODOLOGY: This is a study protocol for a cluster-randomized controlled trial conducted in 10 comprehensive health service centers (CHSCs) in Islamshahr, Iran. A computer-generated random sequence will assign five centers to the intervention group and five to the control group. The allocation sequence will be prepared and concealed by an independent epidemiologist not involved in recruitment or intervention delivery. From each center, 25 eligible health ambassadors (women aged 25-45 years with ≥ 2 years of experience) will be randomly selected, yielding a total sample of 250 participants. The intervention group will receive an eight-session, culturally adapted MHFA training package delivered using problem-based learning and role-playing methods. Depression literacy (as a key component of mental health literacy) will be assessed at baseline and 2 months post-intervention using the questionnaire developed by Reavley et al. (2014). For statistical inference, analysis of covariance (ANCOVA) will be employed to examine group differences, and multivariate linear regression will be applied to adjust for potential confounders, using SPSS software version 24. A p-value of < 0.05 will be considered statistically significant. DISCUSSION: This protocol describes a trial designed to evaluate whether mental health first aid (MHFA) training with a critical thinking approach can improve depression literacy (as a key component of mental health literacy) among health ambassadors. Findings from this study may provide evidence to guide future mental health promotion strategies, particularly for the early identification and referral of individuals with depression and the prevention of suicide.
