As a tool to collect data, the efficiency of online questionnaire depends on the number of completed questionnaires that return from respondents. A progress indicator may persuade respondents to finish the questionnaire. It is thus interesting to examine factors related to the progress indicator that may affect the survey completion. This study examined the effects of (1) formats (2) display rates (3) appearances and (4) positions of progress indicator on completion rates, and time to complete online questionnaires. This study is based on a quasi experiment. The analysis indicated that the effect of display rates of progress indicator is statistically significant on completion rates at the 0.05 level, but the effects of (1) formats (2) appearances or (3) positions of progress indicator were not significant. In addition the effects of all independent variables on the completion time were not significant. In addition to extending knowledge of online questionnaire’s design, researchers could apply the findings so data from their online questionnaires could be of acceptable quality.
