The patient enablement instrument for back pain turkish version, validity and reliability study

Area of Science:

• Rehabilitation Medicine
• Clinical Psychology
• Health Sciences

Background:

• The Patient Enablement Instrument for Back Pain (PEI-BP) is the sole instrument assessing self-management in individuals with low back pain.
• Validating culturally specific instruments is crucial for accurate patient assessment.

Purpose of the Study:

• To develop and validate a Turkish version of the Patient Enablement Instrument for Back Pain (PEI-BP).
• To assess the reliability and validity of the Turkish PEI-BP for low back pain patients.

Main Methods:

• Cross-cultural adaptation and validation of the PEI-BP in 67 Turkish low back pain patients.
• Reliability assessed via test-retest, internal consistency (Cronbach's α=0.886), and repeatability.
• Validity evaluated through structural, content, face validity, and correlation with pain intensity, BIPQ, FABQ, ODI, and SF-36.

Main Results:

• The Turkish PEI-BP demonstrated high reliability (ICC=0.795) and strong validity.
• No floor or ceiling effects were observed, indicating comprehensive measurement.
• Correlations with other measures ranged from weak to good, supporting construct validity.

Conclusions:

• The Turkish version of the PEI-BP is a reliable and valid instrument.
• This validated tool can effectively evaluate the self-management abilities of Turkish-speaking individuals with low back pain.
