    Patient-reported outcomes (PROs) are widely used but may suffer from data quality issues like recall bias.

  • 3

    Digital performance outcomes (PerfOs) can enhance accessibility and lower costs, yet their validation in mHealth remains limited.

  • 4

    The Physical Performance Test (PPT-9) is a validated tool for assessing physical function, linking well with patient-reported measures.

    This study aims to evaluate the psychometric properties of a self-administered digital version of the PPT-9 in psychosomatic patients.
