    Article - En anglais

    Fulltext.

    To determine whether leaving messages on answering machines would aid control recruitment via random-digit telephone dialing, a randomized trial was conducted during 1992-1994 involving 1,323 western Washington households with answering machines.

    For the experimental group, a message was left informing them about the study and promising a call-back ; for the control group, no message was left.

    Leaving a message increased the response rate by about 20 percentage points (p=0.002).

    More households were successfully screened for eligible controls, and individuals found eligible were more likely to participate.

    Leaving a message can help to improve response rates in telephone surveys.
