title: [Study of the quality of measurement by the Sickness Impact Profile. Assessment of the reliability of a method to determine the functional level of psychiatric patients].
abstract: The Sickness Impact Profile (SIP) is a questionnaire method of assessing the functional level within 12 fields which together provide a generalized measurement of the level of health in agreement with the definition of health by WHO. In the present investigation, the method was employed for the first time occasion for 58 suitable psychiatric patients and the result of Rasch's item-analysis of the replies to the individual questions showed altogether scales of good measurement quality. A single question, however, appeared to be unsuitable. The item-analysis is a demanding measurement for the internal validity and homogeneity and it supplements foreign investigations of the criteria-related validity of SIP.
