Interviewer experience, vocal skills and the recruitment of telephone survey respondents

Although telephone interviewing is the main market research method used in Australia, response rates are often low and possibly declining overall. Interviewers are the means by which respondents are recruited and it was hypothesised that their verbal skills and experience would affect response rates. Using data from four market research companies, interviewer experience was shown to be positively related to strike rate (interviews per hour). Apart from having a discernible accent which dampened strike rates and increased refusals, other verbal characteristics had only a weak effect on response rates.
