The Physical Resilience Instrument for Older Adults (PRIFOR) in Surgical Inpatients: Further Evidence for Its Factor...

Area of Science:

• Gerontology
• Rehabilitation Medicine
• Psychometrics

Background:

• The Physical Resilience Instrument for Older Adults (PRIFOR) is established for assessing physical resilience in older adults facing acute health stressors.
• Prior studies confirmed PRIFOR's criterion-related validity, known-group validity, predictive validity, and internal consistency.
• Replicability of PRIFOR in older adults post-surgical treatment remained unverified.

Purpose of the Study:

• To validate the three-factor structure of the PRIFOR in older adults recovering from surgery.
• To assess the concurrent validity of the PRIFOR against measures of depression, cognition, activities of daily living, and frailty.

Main Methods:

• A longitudinal study was conducted in a tertiary-care medical center in Taiwan.
• 207 patients aged 65 and older, who underwent surgery and could communicate independently, were recruited.
• The PRIFOR, Geriatric Depression Scale (5-item), Short Portable Mental Status Questionnaire, Katz Index of Independence in Activities of Daily Living, and Clinical Frailty Scale were administered post-surgery.

Main Results:

• Confirmatory factor analysis supported the three-factor structure of the PRIFOR (positive thinking, cope and adjust lifestyle, belief and hopeful mindset).
• The PRIFOR demonstrated good concurrent validity with depression (r = -0.470 to -0.542).
• Significant associations were found between the PRIFOR and cognition (r = 0.358 to 0.409), activities of daily living (r = 0.209 to 0.310), and frailty (r = -0.161 to -0.237).

Conclusions:

• The PRIFOR is recommended for measuring physical resilience in older adults post-surgical treatment.
• The findings support the PRIFOR's utility in estimating postoperative physical resilience.
• This assessment can guide the implementation of individualized interventions for surgical patients' recovery.
