Basic Information

Abbreviated name
COAST
Full name
Communication Outcome after Stroke
Items ?
The number of questions in the survey
20
Short description
COAST is a patient-centred, practical and reliable measure that can be used to assess self-perceived communication effectiveness for people with stroke, developed in the UK.
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.
Communication in Stroke
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
Respondent ?
The person that fills in the questionnaire - e.g. patient, Health Care Professional, or proxy (normally a carer or family member)

Psychometrics

Brief description ?
A brief description of the initially reported psychometric properties of the measure.
The 29-item COAST scale showed good acceptability (few missing values, sample spread 28-100%), internal consistency and test-retest reliability for the scale (alpha = 0.95; ICC = 0.90) and its subscales (alpha = 0.65-0.93; ICC = 0.72-0.88), but possible item redundancy. A revised scale of 20 items was produced, demonstrating good internal consistency and test-retest reliability (alpha = 0.83-92; ICC = 0.72-0.88).
Co-developed with patients ?
Whether the measure was co-developed with patients, a critical stage in the design and implementation of truly person-centred measures.
Y
CTT or IRT ?
Whether the measure uses Classical Test Theory, or the newer Item Response Theory
