I am studying for a Msc in Psychology and my project is based on the adjustments made by those skilled workers when living in the uk. I have sent emails to organisations with no response. Is there another way I can invite participants?
Recruitment is a key issue in focus groups, so that you typically need to have a strong list of potential participants to bring enough of them together for a discussion session.
If you are having trouble doing that, then I would recommend individual interviews. After you find a few participants through convenience sampling, you could have them recommend other participants through snowball sampling.
A third alternative is to use dyadic interviews, where you would bring together pairs of participants to share and compare their thoughts and experiences. This would be similar to a "mini-focus group."
eMailing organisations is not a good basis for recruitment - people are busy and emails are easily ignored. Two thoughts - why should people help you? Usually focus group organisers offer a financial incentive, but you may not be able to do this; so is there something else you can offer as a reward for participating, such as (for instance) a chance to network with others in a similar situation to you, or others with similar backgrounds? Secondly, try to recruit in person. Focus groups are inevitably local (unless online) and if you hang around places frequented by your target audience, you may have more success approaching them directly. For instance, hospital canteens and coffee shops are a good place to intercept skilled health service workers. And a final bonus thought - choose your venue/time carefully. Don't make it a place difficult to reach, or set your time at an inconvenient hour.
