Popis: | The most important finding of this section is that unusually low levels of interviewer effects were measured in the telephone survey. This result may be due to the stringent controls on interviewer behavior that were introduced in this study but were absent in past studies. These low interviewer variances inhibited attempts to explain interviewer variability on the health variables. Because there was little interviewer variability, the correlates among the monitoring data were weak, and the findings did not exhibit consistency over variables. |
