CAPI for the studies that need interviewers in-market

Tablet-based in-person interviewing across the Caribbean. In-home, central location and retail intercept fieldwork with GPS-validated routes, photo capture and complex script capacity.

Typical Scale
300 to 1,200 interviews
Modes
In-home, CLT, intercept
Output
Dataset with GPS validation
Timeline
3 to 6 weeks
What It Is
Fieldwork where the interview needs to happen in front of the product

Some questions cannot be answered down a phone line or on a laptop. Pack recognition, shelf-impact tests, concept boards, taste tests, on-pack claim comprehension, anything physical. CAPI is the method for those.

We run CAPI out of a network of trained field interviewers across Trinidad, Jamaica, Guyana, Suriname, Barbados and the OECS. Every interview runs on a tablet with CAPI software, GPS time-stamping and photo capture. Fieldwork supervisors route and validate each day's interviews so the dataset that arrives is already audited.

Typical engagements include in-home interviews, central-location product tests, retail intercepts and shop-alongs. Survey length runs comfortably to 30 minutes.

When To Use It
Five jobs that need a tablet in a hand
CAPI is the spend when the interview requires seeing or handling something. Product, pack, shelf or stimulus. Or when the population needs an interviewer at the door.

Pack and shelf tests

Show a pack, a shelf photo or a mock-up and capture reactions on the spot. The respondent is looking at the real thing, not describing it from memory.

In-home interviewing

Household categories where the answer depends on what is actually in the kitchen, the bathroom or the shopping bag. The interviewer is in the room with the product.

Retail intercept

Mall, supermarket or fuel-station intercepts for categories where the decision happens in the moment and memory decays by the time the respondent gets home.

Long-form complex scripts

Studies past 25 minutes. CAPI holds up where CATI drops out and online break-offs kill the sample. The interviewer keeps the respondent engaged.

Product preference testing (60/40)

Sequential monadic taste, use and pack tests with paired-product preference scoring. Two products, blind, in rotation. The interviewer manages the rotation, palate cleanse and timing so the test is administered the same way every interview.

How We Do It
Five steps from brief to validated dataset
Face-to-face fieldwork without discipline is how bad data gets into good reports. These are the checks that keep a CAPI study honest.

Sample and route plan

Enumeration districts or retail locations chosen against a representative frame. Routes clustered so field time is spent interviewing, not travelling.

CAPI script build

Questionnaire coded into the tablet software with full routing, rotations and stimulus handling. Photo capture fields built in where the brief needs them.

Interviewer training and pilot

Full-day briefing, role-play and a 10-interview pilot per region before launch. Issues surface before the main field goes live.

GPS-validated fieldwork

Every interview is GPS time-stamped. Supervisors review route logs daily. Interviews that fall outside the sample frame or below timing thresholds are flagged and re-done.

Back-check and dataset

Fifteen percent back-check on completes, phone or in-person. Dataset cleaned, labelled and delivered in SPSS or Excel with topline tabs inside a week.

What You Get
Field data with the audit trail built in

Four outputs at close. Built so a client-side researcher, a regulator or an agency partner can follow exactly where each interview came from.

  • Dataset. SPSS or Excel with labels, quotas documented, weights applied where the plan calls for it.
  • GPS validation log. Time and location of every interview with the back-check status noted. Fifteen percent re-contact documented.
  • Photo capture library. Where shelf, pack or in-home photos were part of the brief, the images are indexed against the dataset.
  • Topline and full report. Topline tabs in a week. Written report written to the business question, not a restatement of the tabs.

Common Questions
What clients ask before commissioning field
In-home or intercept?

In-home fits household categories, personal care and anything where the respondent needs to reference what is actually in the house. Intercept fits impulse, retail, FMCG and anything where the decision happens at point of sale. Most briefs use one or the other. Hybrid designs are viable when the budget allows.

Is tablet always better than paper?

Yes for anything with routing, complex stim or a sample size above about 200 interviews. Paper still has a niche for very rural work where tablet battery life becomes a logistical constraint. We stock both and choose per brief.

Can you capture photos during the interview?

Yes. Shelf photos, pantry inventories, on-pack claim photos, shopper bags. The tablet fields include photo capture and every image is linked to the respondent record in the dataset. Photos stay on the interviewer tablet until sync, then upload to the study server.

How do you stop falsified interviews?

GPS time-stamping flags interviews that are too fast or in the wrong location. Supervisor review runs daily. Fifteen percent back-check by phone or in person. Interviewers who fail validation are removed and their interviews re-done. Every step is documented in the disposition report.

Which Caribbean markets do you cover?

Trinidad and Tobago, Jamaica, Guyana, Suriname, Barbados and the OECS directly. For Belize and the French and Dutch Caribbean we partner with in-country field teams under our supervision and QC protocols. Spanish-speaking markets are covered with bilingual interviewers.
