What is Experience Sampling Method (ESM)?

Experience Sampling Method (ESM) is a research technique that prompts people to answer short questions repeatedly in real time so researchers capture thoughts, feelings and behaviours as they happen. It reduces recall bias and shows how experiences vary across situations and time.

ESM (also called ecological momentary assessment) collects brief, repeated responses from participants while they are living their daily lives. Instead of asking people to remember how they felt last week, ESM sends short prompts at scheduled or random times, or when a specific event occurs (for example, after using a service). Prompts can be single-choice items, numeric ratings, or short open-text fields. The method is useful for measuring fluctuations (mood, pain, satisfaction), context (location, who they were with) and behaviour patterns. Strengths: more accurate, context-rich data. Trade-offs: higher participant burden, need for clear scheduling and consent, and attention to privacy. For multilingual projects, prompts are translated into participants’ preferred languages and their free-text answers can be translated back for analysis.

Usage example

A council wants real-time feedback on a new bus route: riders get a short survey link after boarding (or randomly during the week) asking about punctuality, crowding and overall satisfaction; responses are collected in each rider’s language and translated for the transport team to review.

Practical application

ESM matters because it uncovers how experiences change in the moment — not just how people remember them later. That helps organisations spot service problems as they occur, measure the impact of changes over time, and design interventions targeted to real situations. For Hearo users, ESM makes feedback more accurate and actionable while still being inclusive: one survey can be delivered in multiple languages, participants answer in their preferred language without creating an account, and administrators see responses translated back for analysis. To get good ESM data, keep prompts short, limit frequency, provide clear opt-out instructions and test translations with community members.

FAQ

How is ESM different from a standard one-off survey?

ESM gathers many short responses over time from the same participants to capture their moment-to-moment experiences. A standard survey asks people to recall past experiences at one point in time, which can introduce recall bias and miss variation across contexts.

Won't repeated prompts annoy participants and reduce response rates?

Careful design reduces burden: limit frequency, keep each prompt very short, let participants choose preferred times or pause notifications, and explain the purpose. Response rates vary, but clear communication, simple questions and delivering prompts in participants’ preferred language all improve engagement.

Do participants need to install an app or create accounts to take part?

No. ESM can work via mobile-friendly links, SMS or email. Hearo supports one-link surveys that open in the participant’s chosen language without requiring accounts, which lowers the barrier to participation.

How do we analyse free-text answers collected in different languages?

Platforms like Hearo translate participants’ responses back into the administrator’s language for review and analysis. You can also retain original-language text, allow community members to flag problematic translations, and iteratively improve wording to ensure accuracy and cultural appropriateness.
