Short description
Symptom based Depression questionnaire, widely used in UK (e.g. in IAPT service), good evidence of diagnostic and discriminant validity, and used to evaluate services. Not intended for use in severe mood disorder.
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.

This is the key domains that the measure is targeting.
Depression specific - symptoms
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”.
PROM

Patients
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.
