Simpler modified Fried frailty scale: translation and validation into Spanish.

Area of Science:

• Gerontology
• Clinical Assessment
• Health Sciences

Background:

• The Fried phenotype is a widely used frailty assessment scale.
• Its clinical implementation can be challenging.
• A simplified Turkish version exists, prompting translation and validation for Spanish use.

Purpose of the Study:

• To translate and validate a simplified, modified Fried frailty phenotype into Spanish.
• To assess the reliability and validity of the Spanish version.

Main Methods:

• Cross-sectional study with 100 participants.
• Evaluated internal consistency, inter-rater reliability, and test-retest reliability.
• Assessed criterion validity against the modified Fried and FRAIL scales, including sensitivity and specificity.

Main Results:

• Excellent inter-rater (kappa=0.83) and test-retest (kappa=0.86) reliability.
• Moderate internal consistency (Cronbach's alpha=0.67).
• Moderate criterion validity (kappa=0.50-0.51), 63% sensitivity, and 89% specificity.

Conclusions:

• The Spanish version demonstrates excellent reliability.
• Internal consistency and validity are moderate, with low sensitivity.
• Limitations may impact frailty detection utility, possibly due to sample or cultural factors.
