Turkish Version of The Diabetes Quality of Life Brief Clinical Inventory Validity and Reliability

Study Overview
=================
Brief Summary
-----------------
This study aims to develop Turkish version of the Diabetes Quality of Life Brief Clinical Inventory (DQL-BCI) and to perform validity and reliability evaluations.

Detailed Description
-----------------
The study will be carried out in two phases: DQL-BCI will be translated into Turkish and adapted to the cultural context, and the reliability and validity of the Turkish version of DQL-BCI will be investigated. The translation process will be performed in accordance with generally accepted international principles of translation and cultural adaptation of measurement tools. At least 150 subjects with type 2 diabetes will complete the Turkish version of DQL-BCI, the EQ-5D-3L questionnaire and the SF-12 quality of life questionnaire. The examination will provide information about the reliability and the construct validity of the studied tool.

Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Study Group<br>Patients with diabetes (all types) | Other: Questionnaire<br>* The original form of the Diabetes Quality of Life-Brief Clinical Inventory was first developed in 1999 to establish a valid and reliable form of diabetes-specific quality of life. Inventory items were developed to address the issues that have the greatest impact on assessing patient self-care behaviors and satisfaction with diabetes care. Items are ranked on a 5-point Likert scale and are in two general formats. One format includes satisfaction with treatment and quality of life and is scored from 1 (very satisfied) to 5 (not very satisfied). The second format includes the frequency of adverse effects of diabetes itself or diabetes treatment and offers response options from 1 (never) to 5 (always). Therefore, higher scores on the DQL-BCI items and subscales include negative values indicating problem frequency or dissatisfaction. In order to use the DQL scale more efficiently in clinics, Burroughs et al. organized the 15-item DQL-BCI in 2004.<br>|

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| The Diabetes Quality of Life - Brief Clinical Inventory | The questionnaire consists of 15 questions, with no grouping into subscales or domains. Items are in two general formats. The first format is about the frequency of negative impacts of diabetes or odiabetes treatment and provides response options from never to all the time. The second format is about the satisfaction with the treatment and QoL, and patients provide answers by selecting from very satisfied to very dissatisfied. Answers to each question correspond to a score of 1-5, and 1 is the lowest score of a given parameter and 5 is the highest. The total score is the sum of scores of individual questions. The scoring ranges from 15 (the worst assessment of QoL) to 75 points (the best assessment of QoL). | 1 week |
