Audit diabetes-dependent quality of life questionnaire: usefulness in diabetes self-management education in the Slovak population.
OBJECTIVE
This paper reports a study to test validity and internal consistency of the audit diabetes-dependent quality of life questionnaire in the Slovak population and to evaluate its usefulness in the context of education of people with diabetes.


BACKGROUND
The individualised instruments designed to measure individuals' perceptions of the impact of diabetes on their quality of life may be helpful to identify individuals' preferences, motivational deficits in diabetes management and to tailor individual treatment strategies.


METHODS
Survey.


METHODS
After linguistic validation, the structure of the questionnaire was tested using factor analysis on 104 patients who were recruited from the National Institute of Endocrinology and Diabetology in Lubochna. Internal consistency was evaluated by computing Cronbach's alpha. Clinical variables related to the quality of life were analysed using one-way ANOVA, multifactor ANOVA, Pearson's and Spearman's rank correlation coefficients.


RESULTS
A one-dimensional scale structure was supported and internal consistency was high (alpha = 0.93). Variance in impact of diabetes on quality of life was explained by age, presence of late complications and type of insulin regimen.


CONCLUSIONS
The audit diabetes-dependent quality of life is culturally appropriate, valid and reliable in the sample of Slovak patients attending the educational programme. Our results agreed with previous European and Asian studies supporting its usefulness in the context of diabetes self-management education.


CONCLUSIONS
Individualised diabetes-specific quality of life measures allow better understanding of patients' treatment preferences and, consequently, more effective prioritizing and targeting of appropriate educational interventions. This instrument may be useful in routine clinical practice and as an outcome measure for international clinical research trials evaluating effectiveness of educational programmes.
