The very first impression that you succeed in creating is crucial to decide the effectiveness of survey. Rather than simply jumping to ask question, give the person at least a concise context of interview. Make him feel that his involvement is important and is valued. Never commit the mistake of dwelling deeper into the details; start with a small introduction as this is significant for making the interviewee stay pleasant and comfortable.
The initial 30 seconds can be considered as most important for your CATI research. You can in this period, understand the respondent’s orientation, willingness to participate and mood. Based on this, you should adapt the tone and speed of question reading process. If they intimate any objections, try to tactically convince but if you feel the heat, stay way to prevent brand value degradation. Detect when the person is not listening and bring him back by clearly repeating the question in a cheerful manner.
