    In clinical psychosomatics there is a need for adequate documentation of psychometric data both within the framework of individual diagnostics and in carespecific quality assurance. The data collection method should meet current psychometric standards, while at the same time allowing a fast and economical evaluation. In contrast to conventional methods using paper and pencil, computer-assisted testing offers considerable advantages in both regards. Using data collected from 6434 patients between the years of 1995 and 2002, we investigated what effects the complete conversion of a psychometric basis assessment to a mobile, computer-assisted method had in terms of acceptance, data structure, and economy. We implemented the following questionnaires, among others: the Center for Epidemiologic Studies-Depression (CES-D) Scale, the Giessen Complaint Inventory (Giessener Beschwerdebogen GBB), the Berlin Mood Questionnaire (Berliner Stimmungsfragebogen BSF), the State-Trait-Anxiety Inventory (STAI), the Short-Form 36 (SF-36), the WHOQOL-Bref, the Giessen Test (GTS), the Narcissism Inventory (NI), and parts of the Psychosomatic Basis Documentation (PsyBaDo). Based on our experience, we can conclude that 1. testing by means of mobile PDA's enjoys a high rate of acceptance among patients, 2. the organization of data is considerably improved, which guarantees an immediate evaluation for clinical and scientific lines of questioning, 3. no significant alterations result in terms of the psychometric characteristics of the questionnaire, and 4. mobile computerized testing is two-thirds cheaper than conventional testing using paper and pencil.

    Mobile und stationäre computergestützte psychometrische Diagnostik

    Questionnaires are one of the foundations of psychometric measurement in clinical psychosomatics. We collected mobile computer-based assessments of psychometric data from more than 7000 patients between January 1995 and December 2002. Our experience has shown that this mobile approach enjoys a high acceptance among patients, is effective and two-thirds cheaper than conventional questionnaires using paper and pencil. This positive evaluation of mobile psychometric computer-based assessments is partly due to the high standardisation and item structure of questionnaires frequently used in psychosomatic diagnostics. Questionnaires with long item descriptions or a long list of choices are much harder to implement on a mobile platform. However, parallel assessments using mobile equipment, personal computers and paper and pencil questionnaires have to be integrated into the clinical data organisation. We report on recent developments of our psychometric assessment system which aim at further integration of different platforms in order to reduce organisational efforts. Another aspect of this development concerns how new psychometric methods such as computer adaptive testing can be used effectively in such an environment.
