Pre-test data were collected from patients with Patient Information and Follow-up Form, Diabetes Self-Management Scale (DSMQ) and Short Form-36 Quality of Life Scale (SF-36). After the pre-test, a educational program and a game-based mobile technology application were carried out for 4 weeks, 2 days a week at intervals. After the educational program were completed, motivational interviews were conducted once a week for 4 weeks. In this process, it was ensured that the game-based mobile technology application continued. Post-test data were collected with DSMQ and SF-36 at 2 months (8 weeks after the pre-test). After the post-test, the patients were followed up for 4 weeks. After the follow, with the Patient Information and Follow-up Form, DSMQ, SF-36, and the Satisfaction Questionnaire the follow-test data was collected.

Pre-test data were collected from patients with Patient Information and Follow-up Form, Diabetes Self-Management Scale DSMQ) and Short Form-36 Quality of Life Scale (SF-36). After the pre-test data were collected, no intervention was applied to the patients for 3 months (12 weeks), except for routine nursing care. Posttest data were collected with DSMQ and SF-36 2 months (8 weeks) after the pretest data. After the last test, the patients were followed up for 4 weeks, and 3 months (12 weeks) after the start of the study, the Patient Information and Follow-up Form (only the parts containing the features related to the disease and metabolic control variables), DSMQ and SF-36 Scale and follow-up test data were collected.

Education program, game-based mobile technology and motivational interview were applied to the patients in the experimental group. The patients' self-management, quality of life, and satisfaction level scores for the intervention were determined.

The scale is of a four-point Likert type. The scale has 4 sub-dimensions as "Glucose Management, Diet Control, Physical Activity, Health-Care Use" and a total score. The lowest score of the scale is 0 points and the highest score is 10 points. The higher the score, the higher the diabetes self-management.

The scale consists of 36 items and 8 sub-dimensions. 8 sub-dimensions have 2 summary sub-dimensions as "Physical Health and Mental Health". There is no total score in the scale. A score between 0-100 is evaluated with sub-dimensions (0: Poor Health, 100: Good Health). Low scores on the scale indicate poor health, while high scores indicate good health.
