Computer-assisted self-monitoring of subjective experience has become one o
f the most promising methods of behavioral assessment in multidisciplinary
pain diagnosis and therapy. This technical report presents a PC software, c
alled 'Elektronisches Bonner Schmerztagebuch' (Electronically Bonn Pain Dia
ry), which provides 1. estimators for intensity, affective, and sensory qua
lity of pain based on the scaling of verbal descriptors and 2. self-report
data for various topics such as hassles, duration of pain, sleep, and medic
ation. This desktop software (Visual Basic under Excel 97, Windows 95 and h
igher) allows data acquisition and automatic evaluation in in-patient setti
ngs. The automatic evaluation comprises graphical and statistical analysis
of time series data. Furthermore, parameters for scaling consistency are pr
ovided. Later reduces the vulnerability to several scaling biases. Applicat
ion and interpretation are described in detail.
