Patient-reported outcome

A patient-reported outcome or PRO is a questionnaire specifically used in clinical trial research. A PRO can be used to register the Quality Of Life (QOL) of a clinical trial participant during a clinical trial.

In general a PRO consists of a physical component and a mental component. The physical component measures items such as general health, physical function, and bodily pain. The mental component in general deals with items such as mental health, emotional role, social functioning and vitality.

Generic PRO tools are the SF-36 Health Survey (SF-36® Health Survey), SF-12 Health Survey (SF-12® Health Survey), Duke Health Profile (DUKE), and BASIS-32, to name a few.

Condition specific tools are the Adult Asthma Quality of Life Questionnaire (AQLQ), Migraine Specific Quality of Life (MSQOL) and the Seattle Angina Questionnaire (SAQ), to name a few.
