Investigational drug(s) / intervention(s)

Duke Activity Status Index (DASI)

Duke Activity Status Index (DASI): The Duke Activity Status Index (DASI) is a 12-item self-administered questionnaire used to assess functional capacity based on activities of daily living. The total score ranges from 0 to 58.2, with higher scores indicating better functional capacity. The Turkish version of the DASI will be administered at the initial assessment and repeated after 7 days to evaluate test-retest reliability.

Study summary

This study aims to evaluate the validity and reliability of the Turkish version of the Duke Activity Status Index (DASI) in women with lipedema. DASI is a 12-item questionnaire designed to assess functional capacity based on activities of daily living. The study will examine the test-retest reliability and internal consistency of the Turkish DASI and investigate its validity by examining its relationships with functional exercise capacity, lower extremity function, and health-related quality of life. The findings are expected to determine whether the Turkish DASI is a valid and reliable tool for assessing functional capacity in women with lipedema.

Primary outcome measure(s)

  • Test-Retest Reliability of the Turkish Duke Activity Status Index — Baseline and 7 days
    Test-retest reliability of the Turkish version of the Duke Activity Status Index (DASI) will be evaluated by administering the questionnaire twice, with a 7-day interval. The DASI consists of 12 items assessing functional capacity during activities of daily living, with a total score ranging from 0 to 58.2; higher scores indicate better functional capacity. Test-retest reliability will be assessed using the intraclass correlation coefficient (ICC).
  • Construct Validity of the Turkish Duke Activity Status Index — Baseline-7 days
    Construct validity of the Turkish DASI will be evaluated by examining the relationships between DASI scores and the Six-Minute Walk Test (6MWT), Lower Extremity Functional Scale (LEFS), and 36-Item Short Form Health Survey (SF-36). Correlation analyses will be used to determine the strength and direction of the relationships between these measures.
