Technology-mediated screening interviews for youth mental health: Content validation, randomized controlled trial,...

Early identification of mental health disorders in children and adolescents is essential for optimal outcomes, yet access to specialist psychiatric assessment remains limited by severe workforce shortages and geographic barriers. This study examines content validity, feasibility and acceptability from youths' perspective, and clinical utility from experts' perspective of technology-mediated screening interview for youth mental health assessment through three sequential investigations (ISRCTN Registry, ISRCTN68006163, registered on 16/04/2025). First, content validity was established through expert evaluation, demonstrating that all screening questions met established psychometric criteria for relevance and clarity. Next, a randomized controlled trial evaluated feasibility and acceptability (satisfaction and willingness to repeat with the same modality) across psychiatrist-led, chatbot, and robot modalities among 106 young patients aged 10-19 receiving mental health treatment. Finally, expert clinical evaluation of recorded interviews assessed clinical utility across modalities. Psychiatrist-led interviews achieved higher satisfaction scores, particularly for communication quality, while willingness to repeat screening did not differ significantly across modalities. Personality characteristics, specifically conscientiousness and open-mindedness, predicted satisfaction with communication across all conditions. Finally, expert clinical evaluation of recorded interviews revealed comparable ratings across modalities for most dimensions, with only alignment with other assessment methods favoring psychiatrist-led approaches over robot-delivered interviews. The results show technology-mediated screening, using the proposed interview, demonstrates acceptable content validity, user feasibility from youth perspective, and clinical utility from expert perspectives. These findings support implementation of accessible, self-administered screening tools as complementary first-step assessments that maintain clinical relevance while expanding access to mental health evaluation for youth populations in underserved settings where specialist availability is limited.
