Pilot study on the psychometric properties of a digital self-administered physical performance test: Evidence from psychosomatic patients - Summary - MDSpire
To assess the psychometric properties of a novel tablet-based, self-administered PPT-9 version in individuals receiving psychosomatic care.
Approach:
Internal Consistency: Examine the internal consistency of the digital version of the PPT-9.
Agreement Assessment: Assess agreement between self-administered and observer-based PPT-9 scores, focusing on timing discrepancies.
Construct Validity: Examine associations between scores from the digital and original PPT-9 versions and the PROMIS PF measure.
Key Findings:
The PPT-9 is a validated instrument for evaluating physical function.
The digital adaptation of PPT-9 is designed for home-based settings using common household objects.
The internal consistency and agreement with observer-based scores of the digital PPT-9 require systematic investigation.
Interpretation:
The study aims to validate a self-administered digital version of the PPT-9 for psychosomatic patients.
Limitations:
Limited psychometric validation of digital self-administered PerfOs.
Previous research primarily focused on older adults, limiting generalizability.
Conclusion:
The pilot investigation seeks to establish the reliability and validity of a digital version of the PPT-9 for diverse health conditions in psychosomatic care.
A healthy lifestyle was associated with a smaller loss of disease-free life expectancy related to social isolation, but the same pattern did not hold for loneliness.
