Examining the Validity and Reliability of the Dresden Falls Questionnaire in Patients With Parkinson's Diagnosis Living in Turkey

The aim of this study is to adapt the Dresden Falls Questionnaire scale (DREFAQ) to Turkish society and to make its validity and reliability in Turkish. The DREFAQ) scale developed by Frank, Anika, et al assesses falls in patients with Parkinson. It has 5 questions. This study will be conducted with Parkinson patients. The patients will be sought to answer questionnaires during regular rehabilitation sessions. 50 participants will be included in the study. In order to evaluate the validity of the DREFAQ, the Modified Falls Efficacy Scale (MFES), which can evaluate the efficacy of falls and has been validated in Turkish, and the Parkinson's Disease Quality of Life (PDQOL) questionnaire, which can evaluate the quality of life and has been validated in Turkish, will be used. Scales will be repeated after 15 days to assess test-retest reliability.

About this study

The reliability and validity of the scale will begin with language equivalence and cultural adaptation. The scale will be translated from English to Turkish by two people who are fluent in Turkish and English. A single Turkish translation will be obtained from these two Turkish translations with a common opinion.

The scale, which has been translated into Turkish, will be translated into English by two other people who are fluent in Turkish and English. The scale translated into English will be compared with the original. If the developer of the scale, Frank, Anika, et al approves the translation of the scale, participants will be recruited for the study. In the pre-trial phase, a reassessment will be conducted with 15 participants to test the intelligibility of the scale. Based on the results of the pre-test phase, the final version of DREFAQ will be able to be modified. The data of DREFAQ are collecting through face-to-face when the patients came to the rehabilitation center. 50 participants will be included in the study.

In order to evaluate the validity of the DREFAQ, the Modified Falls Efficacy Scale (MFES), which can evaluate the efficacy of falls and has been validated in Turkish, and the Parkinson's Disease Quality of Life (PDQOL) questionnaire, which can evaluate the quality of life and has been validated in Turkish, will be used. Scales will be repeated after 15 days to assess test-retest reliability.

Primary outcomes

  1. Falls

    Time frame: Baseline

    Falls will be assessed with the Dresden Falls Questionnaire scale (DREFAQ). DREFAQ consists of 5 items in total. Items 1 to 4 are scored from 0 to 3. The total score of the DREFAQ is calculated by summing the first 4 items (0-12). The location of the injury (from item 4) and the circumstances (item 5) are not used in the score calculation but provide additional qualitative information. Higher scores indicate a high risk of falling.

  2. Falls Efficacy

    Time frame: Baseline

    Falls efficacy will be assessed with the Modified Falls Efficacy Scale (MFES) scale. The MFES consists of 14 items in total. Items are scored from 0 (not sure of himself/herself) to 10 (totally confident). Total score is between 0-140. Lower scores indicate a high risk of falling.

Secondary outcomes

  1. Health-Related Quality of Life (HRQoL)

    Time frame: Baseline

    Ouality of life will be assessed with the Parkinson's Disease Quality of Life (PDQOL) questionnaire. It consists of 8 questions in total. Items are scored 0 to 4. Total score is between 0-32. Higher scores indicate lower quality of life.
