Validation of a multidimensional questionnaire to assess adaptation to illness to renal patients under dialysis treatment designed from a questionnaire from oncohaematologic patients

Abstract

Objectives: The present study aims to explore the psychometric properties of a multidimensional questionnaire to assess adaptation to illness in patients with end stage renal disease under hemodialysis (CMAE-RD for its Spanish acronym). Methods: This instrument was developed to be administered by a psychologist as a semi structured interview and it was adapted from a previous questionnaire for patients with oncohaematologic diseases. A total of 113 patients receiving hemodialysis treatment were interviewed with the CMAE-RD and completed two additional questionnaires with validation purposes: the HADS (to assess anxiety and depression) and the CDRISC-2 (to assess resilience). Results: Internal consistency scores for the areas of the CMAE-RD was comprised between.53 and.70. Evidences of validity related to an external criterion and concurrent validity were obtained for the areas which assess the level of information of the patient and their emotional state. Conclusions: We conclude that the CMAE-RD shows adequate levels of reliability and validity, being a useful measurement tool from the standpoint of health care, as it allows psychologist the needs and resources of renal patients, providing guidance for psychological intervention.
