Once the client has approved the respondent recruitment screener the 'internal' market research field recruitment team (to ensure the very best and genuine respondents we do not use external recruiters) begins the process of recruitment. Often, our first port of call includes contacting our vast database with a blind requirement (unlike most other agencies - and to ensure truthful responses - we will not 'lead' respondents by giving them details of the project requirement). Our registered respondents will then complete the online screener which will assess their suitability for the research. As standard policy, participants can only complete the recruitment screener once, they are not allowed to backspace or 'retry' after receiving a screen-out, and we do not openly discuss the exact criteria for any project, ever.
Recruitment screeners are made in a way that it's impossible for respondents to tell who we're really looking for. Duplicitous and 'professional respondents' can never be fully avoided - we'd be lying if we said otherwise - but our fully blind and tested system and protocols ensures a very limited instance of such individuals (less than 1%).
Where the database hasn't returned suitable respondents, or where we need a little more interest, we'll then turn to outreach as we have a foothold in many local community groups, local services, and social media campaigns - so we turn to these first, before making new, local connections if necessary.
All respondents are triple checked to confirm suitability. This is how we guarantee a good quality sample in all of our self-recruited focus groups. Respondents are blind screened, actively spoken to by a member of our team to verify that their details match (we often re-ask key questions again, checking their responses match), and in some cases where participants are classed as 'hard-to-reach', we will even request proof or check suitability.
