A client-computer interface for questionnaire data.
Our purpose was to assess efficiency and patient acceptance of a simple, inexpensive method of direct client-computer interface. A computerized version of the Sickness Impact Profile (SIP) was developed with the standard keyboard replaced by a numeric keypad. Forty-eight volunteer clients of an occupational rehabilitation center completed both the paper format and the computer format in randomized order, then were asked to compare the two methods in four areas. The majority of subjects rated the computer as easier to use and as the preferred method. Most subjects rated the computer and paper formats as equivalent in comfort and understanding. A summary score established that significantly more individuals preferred the computer format over the paper format (p = .02). Efficiency was determined by the mean time to score the test and produce a report (computer 39s, paper 309s). The correlation coefficients for the physical, psychosocial, and overall scores were very acceptable being greater than 0.90. These data indicate that a simple client-computer interface for the SIP is preferred by clients and is more efficient compared to the paper and pencil format.
