Basic Information

Abbreviated name
Full name
Shared Decision Making Questionnaire
Items ?
The number of questions in the survey
Short description
Revised an existing instrument (Shared Decision Making Questionnaire; SDM-Q), including the generation of new items and changing the response format leading to the development of a 9-item version (SDM-Q-9).
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.
Shared decision-making, health related quality of life
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)

Impact ?
A crude indication of the impact of the measure on academia. This is the number of times the original publication has been cited on PubMed, divided/normalised to the years since publication.

Brief description ?
A brief description of the initially reported psychometric properties of the measure.
Findings showed that this measure is reliable, it has face validity and is a well-accepted measure (Kriston et al, 2010). A comparison of the SDM-Q-9 and the original OPTION scale (scored by expert observers), strengthened the psychometric standing of the measure, as while the OPTION scale had limited internal consistency and the inter-rater reliability was low, the SDM-Q-9 demonstrated good internal consistency (Scholl, Kriston, Dirmaier & Harter, 2015). Generalizability of these findings is limited however, as it has only been tested within Germany and on a particular sample (the elderly). Therefore, while this measure looks promising, further testing of criterion validity and of its performance in other populations is necessary.
