Brief 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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Construct Validity of the Turkish Version of the Brompton Breathing Pattern Assessment Tool (BPAT) | Baseline | The study aims to evaluate the construct validity of the Turkish version of the BPAT in assessing breathing patterns among Turkish-speaking asthma patients. Validity will be determined by calculating correlation coefficients (e.g., Spearman's or Pearson's r) between the total BPAT scores, objective physiological measures (spirometry results such as FEV1 and FVC), and the scores of established reference clinical tools (Nijmegen Questionnaire, Dyspnea-12, Asthma Control Test (ACT), and Asthma Quality of Life Questionnaire (Mini-AQLQ). |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Test-Retest Reliability of the Turkish Version of BPAT | 7 to 14 days | This outcome will assess the test-retest reliability of the Turkish version of BPAT by measuring the consistency of the tool in repeated assessments. The BPAT will be administered twice to the same participants. Reliability will be evaluated by calculating the Intraclass Correlation Coefficient (ICC). |
| Inter-Rater Reliability of the Turkish Version of BPAT | Baseline | This outcome will assess the inter-rater reliability of the Turkish version of BPAT. Two independent physiotherapists will evaluate the breathing pattern of the same asthma patient. The raters will be blinded to each other's scores to determine the consistency of the tool's application between different users. Reliability will be evaluated by calculating the Intraclass Correlation Coefficient (ICC) or Cohen's Kappa. |
| Comparison of BPAT Results with Other Asthma Assessment Tools | Baseline | Description: This outcome will compare the BPAT results with other validated asthma assessment tools, such as Nijmegen Questionnaire, Dyspnea-12 Questionnaire , spirometry, ACT (Asthma Control Test), and Mini AQLQ (Asthma Quality of Life Questionnaire), to determine the congruence between different assessment methods. |
