Short description
A simple, four-item session by session measure designed to assess areas of life functioning known to change as a result of therapeutic intervention.
PCCC or QoL? ?
This compendium contains patient-reported measures that are either designed to specifically measure aspects of Person Centred Co-Ordinated Care (P3C), or alternatively tools that are designed to measure some aspect of Quality of Life (QoL) or Health Related Quality of Life (hrQoL). All the measures in this compendium have been broadly categorised into one of those two concepts.
Person Centred Coordinated Care
Main Domains Measured ?
This is the key domains that the measure is targeting.
Patient functionality (interpersonally, individually, socially and overall wellbeing)
Type of measure ?
The measures in this compendium can take a variety of forms. Generally, they will be either Patient Reported Outcome Measure (PROM) or Patient Reported Experience Measure (PREM). However, we have also included a few measures that are completed by proxy-individual (PROXY), which are useful in instances where the respondent cannot answer directly (e.g. dementia or end of life). Sometimes, these measures can even be a composite of these types, and target both experiences and outcomes – we have labelled these measures “PROEMs”.
Respondent ?
The person that fills in the questionnaire - e.g. patient, Health Care Professional, or proxy (normally a carer or family member)
Permissive licence ?
Whether the measure is free to use without major restrictions, or instead permission and/or licensing fees are required. E.g. if "Yes", you should seek authorisation/permission prior to using the instrument.
A license to use the ORS is available for free to
