The Turkish Version of the Activity Diversity Questionnaire

Older Adults Clinical Trial

Official title: Validity and Reliability of the Activity Diversity Questionnaire for Turkish Older Adults

Status Completed

Clinical Trial Summary

The Activity Diversity Questionnaire (ADQ) was developed to assess activity diversity. The questionnaire consists of 20 items rated on a four-point Likert scale. This questionnaire defines activity diversity using Shannon's entropy and is the first assessment tool of activity diversity validated for validity and reliability. Important data can be obtained from this questionnaire, such as the relationship between the health status of older adults and their activity diversity. There is no scale in Turkish that can be used to evaluate the activity diversity. The aim of our study was to investigate the relevance of the Activity Diversity Questionnaire for Turkish older adults and the effectiveness of its clinical use.

Clinical Trial Description

The Activity Diversity Questionnaire was developed by Junta Takahashi et al. in 2020 to assess activity diversity. The Activity Diversity Questionnaire was translated into Turkish using the back and forward translation method described by Beaton et al. First of all, the Activity Diversity Questionnaire, whose original text was in English, was translated into Turkish by 2 independent native speakers who have a good command of the culture of the scale and speak English very well. The scales translated from English to Turkish were analysed by another expert who knew English very well, and the translations were synthesized into a single translation. The Turkish synthesis translation of the Activity Diversity Questionnaire was translated back into English by 2 independent native speakers who are also familiar with Turkish culture and know Turkish very well. This phase was completed by people who were not related to the previous translation process and who had never seen the Activity Diversity Questionnaire before. The scales translated from Turkish to English were synthesized and turned into a single translation. This translation was emailed to Shuichi Obuchi, who developed the scale to avoid ambiguity. After obtaining confirmation from Shuichi Obuchi about the accuracy of the translation, the final version of the Turkish version of the Activity Diversity Questionnaire was reviewed, and the assessment of cultural adaptation and adaptation to the Turkish language was carried out by a Turkish linguist. After examining the compatibility of the translations, a pilot study was applied to 40 older adults in order to determine the clarity of the final version of the scale. The meaning of both the items and the responses was checked with the pilot assessment applied to the older adults. Participants completed the scale without any problems and the final version of the scale was created. Test-retest and internal consistency analyzes were applied to determine the reliability of the Activity Diversity Questionnaire. Confirmatory factor analysis with AMOS 26 was used to confirm the scale factors for construct validity analysis. After calculating the total scores obtained from all the scales applied for the criterion validity of the Activity Diversity Questionnaire, a comparison method with a previously validated scale was used using Spearman correlation analysis. ;
