OBJECTIVE:The purpose of this study was to investigate whether a computer interviewing system (CIS) could be used as part of the periodic patient reassessment process, if patients and practitioners perceived that the CIS enhanced communication, and if the CIS could be used to identify patients with possible anxiety and/or depression. METHODS:An observational method was used, whereby the CIS was used to augment the usual patient reassessment routine in a chiropractic clinic. One clinic in the Dundee region, with 3 chiropractors, collected information from 60 patients using a CIS directly before the patient treatment session. The patients were then asked to rate whether they had disclosed new information relative to their care, if they felt better prepared, or if it had helped them to formulate questions. The chiropractors reported whether the interview transcript was useful, if it helped to identify communication issues, and if it had altered the treatment session. RESULTS:The doctors of chiropractic rated the interview transcript as useful for 83% of patients, they altered the treatment session for 20% of patients, and the CIS helped to identify communication difficulties for 13% of patients. The chiropractors were surprised by the Hospital Anxiety and Depression Scale results for 23% of patients. The patients were positive about the inclusion of the CIS, with 42% saying that they disclosed new information and 33% saying that they felt better prepared for the session with the chiropractor after having used the CIS. The CIS was acceptable to 90% of patients. CONCLUSIONS:The inclusion of the CIS at this one clinic appeared to be a useful addition to the periodic patient reassessment process and was perceived to be an efficient media to evaluate Hospital Anxiety and Depression Scale scores.

Toilets and toilet habits are perceived as a taboo subject that people may be reluctant or embarrassed to talk openly about. In the past, appropriately designed Computer Based Interviews have been shown to encourage more honest answers to sensitive questions than other forms of interview, and can be more interesting and engaging that filling out a paper questionnaire. This chapter presents Dundee University's role within the Friendly Restroom project which was primarily to provide Computer Based Interviews and other computer-based requirements gathering tools to be used to elicit toileting requirements of elderly people. Dundee University also investigated the feasibility of using Virtual Reality technologies, such as 3D environments and 360 degree panoramas, to support this information and requirements gathering.

Software design is an area where it is most important to elicit an accurate and complete set of requirements. Determining the users’ requirements and their qualitative satisfaction with a developing product are two major problems which arise, often due to the different backgrounds and perspectives of the different stakeholders, including the software engineer, the domain expert and the end-user. Involving users throughout the design and development process is an essential part of any project. Computer-based interviewing has been found to be a valuable tool in eliciting information, which can also enhance interpersonal communication afterwards. This paper discusses the development of a computer interviewing tool to facilitate the gathering of user requirements and conducting user evaluations.
