CAPI market research agency
Recruitment for CAPIs (Computer-Assisted Personal Interviewing) often involves street intercepts, where participants are stopped in a specific location such as a busy high street and potentially involves product testing. This approach needs to be relatively short, ideally no more than 10 to 15 minutes, as it takes respondents away from their day-to-day life.

Why CAPI?
Why should you conduct CAPI market research?
The CAPI methodology offers significant advantages for studies that require structured yet flexible data collection. It supports complex routing and branching within questionnaires, ensuring that respondents are only asked questions relevant to them. Data is captured in real time, enabling clients to track fieldwork progress and access results immediately once interviews are completed, speeding up insight delivery and decision-making.
CAPI is particularly well suited to research involving physical interaction with a product. Participants can see, touch, taste, or smell items before providing quantitative feedback, leading to more accurate and informed responses. Visual and audio prompts such as videos can also be incorporated to test a wider range of reactions than would be possible in remote methodologies. Interviews are typically conducted in high-footfall locations, either on the spot or in a nearby indoor venue when product testing is required, making this approach both practical and highly engaging for respondents.

Types of CAPI
What are the different types of CAPI?
There are many different reasons for conducting CAPI research. Below we describe some of the common use cases.
CAPI consumer behaviour studies
Understanding purchasing habits, preferences, and decision-making processes through face-to-face interviews, helping to tailor marketing and product strategies.
CAPI product testing research
Gathering detailed feedback on new or existing products via hands-on trials, identifying issues, and understanding product appeal before a product launch or update.
CAPI customer satisfaction surveys
Measuring customer satisfaction with products or services through direct interviews, improving offerings and customer service based on candid feedback.
CAPI brand awareness studies
Assessing brand recognition and consumer perceptions, identifying strengths and weaknesses, and enhancing brand image and awareness.
CAPI public opinion polls
Collecting data on social, political, or economic issues through direct interviews, ensuring accurate understanding and informed decision-making.
CAPI visitor experience studies
Capturing the experience of visitors to a particular event, store or attraction while they are on site or as soon as they leave for fresh and detailed feedback.
Case studies
Case studies of CAPI research
We are experts in recruiting participants for CAPI research in the UK, Europe and beyond. We have successfully recruited for more than 20 CAPI projects and have run this type of research in a number of different countries in Europe and beyond. Here is a small selection of our previous CAPI research.

CAPI, focus groups: mobile top-up retailers
A management consultancy wanted to talk to shopkeepers in London who sell SIMs and top-ups for a mobile virtual network operator. We conducted face-to-face interviews with owners and managers and arranged two focus groups so our client could obtain views on the brand’s positioning relative to other mobile operators.

CAPI: recycling, Saudi Arabia
FieldworkHub supported a research project to encourage the recycling of plastic packaging by consumers in Saudi Araba by conducting face-to-face quantitative interviews (CAPI) with 400 adults outside supermarkets and shopping malls in major Saudi Arabian cites (Riyadh, Jeddah, Makkah, Medina and Dammam) over a period of five days.

F2F quantitative research: beer drinkers, UK
A major beer brand wanted to obtain feedback on a prototype for a new draught beer dispenser, to find out if the design made beer drinkers more likely to select the client’s brand compared to competitor brands. We helped set up a mock bar in a Central London research facility and recruited 300 respondents.

Face-to-face interviews: Barking station, London
Transport for London wanted to improve the environment outside Barking station. They wanted to explore perceptions of safety and test the impact of interventions on people who use the space. We completed 250 face-to-face CAPI interviews outside the station in two research waves.

Street intercepts: shampoo & conditioner tests
A well-known brand of shampoo and conditioner for women wanted to obtain quantitative feedback on some new product fragrances that it was planning to launch in the UK. FieldworkHub was asked to recruit 200 women via street intercepts in both London and Birmingham.

Taste testing: coffee syrups, London
A major syrup brand wanted to assess whether consumers, bartenders and baristas are more likely to select the client’s brand in preference to competitor brands. FieldworkHub recruited 100 consumers, 20 bartenders and 20 baristas for a coffee and cocktail tasting test in London.

The team at FieldworkHub have been an absolute pleasure to work with. We threw in a mid-fieldwork curveball requesting additional sample and the team accepted the request with no issues in delivering. The quality of the sample was high and I have no hesitation in recommending FieldworkHub and look forward to working with them again.

1
What are the benefits of CAPI compared to a standard online survey?
CAPI is a much better market research approach than a standard online survey when you need to collect data from a specific location (e.g. people attending an exhibition, visiting a tourist attraction, or leaving a store) or when the respondents need to provide feedback on their experience of a particular product in a controlled environment (e.g. taste tests, sniff tests etc). CAPI is also very valuable when you need to reach respondents who are under-represented on online panels (e.g. older people and those with low digital literacy or poor broadband connectivity).
2
How long does a CAPI study take to complete?
The duration of a CAPI (Computer-Assisted Personal Interviewing) study can vary based on several factors, but a typical study might take approximately 2-4 weeks, driven largely by the lead time required to recruit and schedule the interviewers and the number of shifts that they need to work to collect the required number of responses.
3
How much does CAPI research cost?
The cost per complete for CAPI research is usually much higher than for a self-completed online survey because it is labour intensive. Also bear in mind that CAPI research charges are usually based on the number of hours that interviewers spend collecting data, rather than the number of responses obtained, because factors such as the weather can have such a big impact on the number of people available and willing to be interviewed.
