We evaluated hand-held computers as an alternative to data collection using traditional pre-printed paper forms. Hand-held computers are relatively inexpensive, easily portable, can provide database connectivity, and eliminate the need for data entry. If programmed to do so, hand-held computers can also provide data validation at the time of collection, helping to eliminate erroneous or missing responses.
We assessed the feasibility of using hand-held computers during an observational study of health-related behaviors at 50 public events in the community. Research staff collected data using both pre-printed paper data collection forms and a hand-held computer. They also completed an anonymous survey detailing their preferences. We found the data from both methods to be highly comparable. As expected, data were processed and ready to analyze much quicker with the hand-held computer than with the paper, and there was also a slight advantage to the hand-held in terms of missing data. Alternatively the learning curve for the paper forms was quicker, and it was also easier to enter text comments on paper. Overall, the research staff expressed a slight preference for the hand-held computers.
The speaker will provide a demonstration of how a hand-held computer works and will describe the relative strengths and weaknesses of data collection via paper forms versus hand-held computers. Participants will be able to identify pros and cons of using hand-held computers for data collection and will be able to evaluate whether hand-held computers would be beneficial for their needs.
