Interviewers' effects in telephone surveys : the case of International Victim Survey

Belak, Eva (author), Vehovar, Vasja (author)

The interviewers' effects is expressed in terms of the interviewers' variance in the case of the International Victim survey. Different methods for variance calculation (Jackknife, Taylor series) were employed to estimate the interviewers' variance and the interviewers' intraclass correlation. It was found that these estimates were very unstable. This was mainly due to the relatively large and variable interviewer's workloads. However, despite this instability the interviewers' effects substantially distorted the precision ofthe estimates. For factual variables (victimization variables), the varianceof the estimates was about two times larger than the variance where the interviewers' effects were ignored. For attitudinal variables (opinions about the survey itself) the increase was even higher.
