The focus group interview technique provides in-depth information on a specific topic in a group discussion setting and can be effectively used with older adults. Successful focus group interviews include careful question preparation and participant recruitment as well as securing a capable moderator and comfortable setting. The technique is used as a preliminary research step to elicit feelings, attitudes and perceptions about a topic. However, results should not be generalized without further quantitative research.
焦点小组访谈技术在小组讨论环境中提供关于特定主题的深入信息，并且可以有效地用于老年人。成功的焦点小组访谈包括精心准备问题、招募参与者，以及确保有能力的主持人和舒适的环境。该技术用作初步研究步骤，以引出对某一主题的感受、态度和看法。然而，未经进一步的定量研究，结果不应一概而论。
