Lower Quadrant Edema Patient-Reported Outcome Measure Is Reliable, Valid, and Efficient for Patients With Lymphatic and Venous Disorders.

Physical therapy·2023

A new self-report measure for shoulder function, the Flexilevel Scale of Shoulder Function (FLEX-SF), was developed and validated. This scale offers reliable and valid assessment, with potential for computer-adaptive testing to improve efficiency.

Area of Science:

  • Orthopedics
  • Rehabilitation Medicine
  • Psychometrics

Background:

  • Shoulder function assessment is crucial for patient care and research.
  • Existing measures may have limitations in scope or efficiency.
  • Development of robust, validated instruments is an ongoing need.

Purpose of the Study:

  • To develop and validate the Flexilevel Scale of Shoulder Function (FLEX-SF), a self-report measure.
  • To evaluate the psychometric properties of the FLEX-SF.
  • To explore the potential of a computer-adaptive test (CAT) format for shoulder function assessment.

Main Methods:

  • Item response theory (IRT) and Andrich's rating scale model were used for item calibration.
  • A pool of 68 items was administered to 400 patients with shoulder complaints.

  • 33 items were selected and organized into testlets; validity and reliability were assessed in 199 patients.

    • Main Results:

    • The FLEX-SF demonstrated high reliability and excellent validity, including responsiveness.
    • The developed item pool supported the simulation of a computer-adaptive test.
    • A computer-adaptive test format showed potential for enhanced measurement efficiency.

    Conclusions:

    • The FLEX-SF is a reliable and valid patient-reported outcome measure for shoulder function.
    • The FLEX-SF can be effectively administered using a computer-adaptive testing approach.
    • Computer-adaptive testing may offer a more efficient method for assessing shoulder function.
