Self-Estimated Functional Inability Because of Pain Questionnaire for Athletes: A Reliability and Construct Validity...

Area of Science:

• Sports Medicine
• Rehabilitation Science
• Psychometrics

Background:

• Pain-related functional inability is a significant concern for athletes.
• Validated questionnaires are crucial for accurate assessment and management.
• The Self-Estimated Functional Inability Because of Pain Questionnaire (SEFIP-sport) is a tool used to measure this inability.

Purpose of the Study:

• To evaluate the psychometric properties of the Brazilian Portuguese version of the SEFIP-sport.
• To determine its reliability, internal consistency, construct validity, and floor/ceiling effects in an athletic population.

Main Methods:

• A cross-sectional validity questionnaire study was conducted.
• 221 athletes practicing regularly were recruited.
• The SEFIP-sport was administered alongside other validated measures for pain, quality of life, and predicted disability.

Main Results:

• The Brazilian SEFIP-sport demonstrated adequate reliability (κ ≥ 0.40, ICC = 0.91) and internal consistency (Cronbach's α ≥ 0.81).
• Significant correlations were found between SEFIP-sport scores and measures of pain intensity, quality of life, and general disability.
• No significant floor or ceiling effects were reported, indicating the questionnaire captures a wide range of functional inability.

Conclusions:

• The Brazilian Portuguese version of the SEFIP-sport possesses adequate psychometric properties.
• It is a reliable and valid instrument for assessing functional inability due to pain in athletes.
• This validated tool can be effectively used in clinical and research settings with Brazilian athletes.
