[Measuring quality of life in weekly assessment of the disease course in myocardial infarct patients--initial results of methodology].

In a quality-of-life study in the first year after successful in-patient rehabilitation following first infarct, a questionnaire method for daily and weekly evaluation of subjective life quality was carried out. The questionnaire presents varying aspects in particular processes concerning the assessment and valuation of life quality. Errors in measurement resulting from processes of memory and revaluation as they are possible in methods with longer intervals of data collection are avoided. An investigation of the reliability of this method revealed good reliability. To definitely assess the validity of this evaluation, further inquiries will be necessary. However, the correlation analysis points to a great significance of the collected weekly data.
