What actually improves understanding and reduces drop-off

When choosing a provider, look for features like:

• Interactive consent with videos, diagrams, FAQs
• Plain-language formatting
• Branching logic so participants only see relevant sections
• Knowledge checks to confirm understanding
• Multilingual support
• Mobile-friendly design
• Ability to pause and resume
• Electronic signature that feels simple and fast
• Site support tools so staff can guide participants without pressure

Best “trust” choices by use case

• Large pharma / global trial: Signant Health, Veeva, Medable
• Decentralized or mobile-first study: Medable, YPrime, Signant
• Smaller academic or mid-market study: Castor, CRIO, RealTime
• If you already use a broader platform: often best to choose the provider in your existing ecosystem to avoid friction
