ABSTRACT
BACKGROUND: Language barriers in mental health care can hinder diagnostic accuracy, communication quality, and therapeutic rapport. Multilingual mental health care providers (MHCPs) or qualified interpreters are not always available, prompting interest in mobile translation apps as alternative tools. The usability of such tools in mental health consultations remains underexplored.
OBJECTIVE: This pilot study aims to assess whether a mobile machine translation app can support MHCPs in conducting accurate mental health assessments with patients who speak a different language. Secondary objectives include assessing usability, communication quality, translation accuracy, and nonverbal interaction in a simulated mental health care setting. The feasibility objectives are to examine recruitment, retention, data completeness, time adherence, acceptability, scenario realism, and resource requirements to inform the design of a larger future trial.
METHODS: This is a single-arm, simulation-based, mixed methods pilot study involving 12 German-speaking MHCPs and 2 Turkish-speaking standardized service users. In this study, MHCPs include both fully trained professionals and individuals in advanced training involved in mental health care delivery. Each health care provider will participate in a simulated mental health consultation lasting up to 30 minutes, using the mobile translation app Mabel, which provides real-time translation during multilingual clinical interactions. Data will be collected via video and audio recordings, app use metrics, postsimulation questionnaires, and optional qualitative interviews. Data will be analyzed using descriptive statistics, thematic analysis, and mixed methods triangulation.
RESULTS: As of March 2026, no participants have been enrolled. The pilot study is being conducted within an ongoing Volkswagen Foundation-funded research project. Preparatory work, including scenario development, scoring rubrics, and data collection materials, is at an advanced stage. Recruitment is scheduled to begin in May 2026, with data collection completion anticipated in July 2026. Results will be reported in a future publication.
CONCLUSIONS: This pilot study will provide initial evidence on the usability and feasibility of mobile translation apps in mental health care and inform the design of a larger implementation study.
