Adaptive Contact Strategies in a Telephone Survey

Greenberg and Stokes (1990) looked at methods that used the history of previous calls to determine the best time to place the next call. Brick et al. (1996) considered a similar approach that used logistic regression models to identify the best time of day, day of week and lag time between calls. Predictors in the model included contextual data as well as information about the results of previous attempts. Others have looked at the impact of various sequences of calls (Weeks et al., 1980; Weeks et al., 1987; Cunningham et al., 2003).
