In the collection of data introductory information form, self-management perception scale in diabetes and diabetes symptoms checklist scale were used. In the analysis of data summarized as number, percentage, mean, and standard deviation, Pearson correlation analysis was used to examine the Student t test, one-way analysis of variance, Tukey’s test, and the bilateral relations between the variables.Results: The mean age of the patients was 53.73±9.2 years; 59.5% were women, 77.3% were married, and 45.5% were primary school graduates. The mean score of the participants in the self-management perception scale in diabetes was 23.26±5.49, and 86.0±31.0 was obtained from the diabetes symptoms checklist scale.
