Summary

The purpose of this study is to evaluate the validity and reliability of the Turkish version of the Brompton Breathing Pattern Assessment Tool (BPAT) in individuals with asthma. This study aims to determine whether the BPAT is a valid and reliable tool for assessing breathing patterns in Turkish-speaking asthma patients. The research question being addressed is: "Is the Turkish version of the BPAT a valid and reliable tool for assessing breathing patterns in individuals with asthma?"

Detailed description

This study is designed to assess the validity and reliability of the Turkish version of the Brompton Breathing Pattern Assessment Tool (BPAT). BPAT is a well-established tool used to assess the breathing patterns of individuals with respiratory conditions. In this study, a group of asthma patients will be evaluated using the BPAT to determine its applicability and consistency in the Turkish-speaking population. The reliability of the tool will be tested through repeated measurements, and its validity will be assessed by comparing BPAT results with other validated asthma assessment tools. The data will be analyzed to evaluate the internal consistency, test-retest reliability, and construct validity of the BPAT in a clinical asthma population. The linguistic validation process will be conducted following the ISPOR Task Force guidelines, including forward translation, reconciliation, back-translation, and cognitive debriefing. The psychometric properties of the tool, including internal consistency, test-retest reliability, and construct validity, will be evaluated according to the COSMIN checklist standards. Additionally, participant eligibility will be defined as individuals who are diagnosed with asthma and can understand and respond to questions in Turkish. The study will also explore any cultural adaptations necessary for the Turkish version of the BPAT to ensure its cultural relevance and accuracy in assessments.
