Focus groups are a popular, widely accepted, and legitimate research method to determine attitudes, experiences, perceptions, and knowledge on a wide range of topics in many fields of endeavor. For example, studies have been conducted to examine participants’ favorite pizza toppings, their quality of life following hip replacement surgery and how they feel about human cloning. Focus groups lead to the voicing of attitudes and insights not readily attainable from other qualitative forms of data collection. The spectrum of interest in focus groups covers virtually all disciplines, and the variety of the applications for this technique is extraordinary. In nine parts, Graham Walden explores what a focus group is, how they are best used, the strengths and weaknesses of focus groups and the ethical issues surrounding focus groups, amongst other things.
