The KON-2006 is a questionnaire enabling the assessment of neurotic personality traits. This paper presents a method of categorising changes in the KON-2006 assessment based on the reliable change concept ( RC). The RC helps to determine whether a given magnitude of change in a patient can be attributed to a real transformation of the subject or whether it is an effect of the imprecision of a given measuring instrument instead. Cut-off point values for a reliable change (RCV) in KON-2006 results are presented. These values were computed for the global index of neurotic disintegration (X-KON) and for 24 subscales of the questionnaire.
