Effective Consumers Scale EC-17

Meeting Argentina

Over the past six years, we have developed a scale to measure “how effective people are at dealing with their chronic condition and making decisions about their health care”. The Effective Consumer Scale (EC-17) consists of 17 items measuring the main skills and behaviours people need to effectively manage their health care.

Development

Following a literature review, semi-structured interviews were conducted with people with arthritis diseases and their networks (e.g. family, health care providers, etc.) to identify a set of skills and behaviours that people need to manage their health effectively. These interviews were supplemented by consultations with key stakeholders, including patient and professional organisations and research experts. After a pilot project of people with arthritis diseases to assess the psychometric properties of the preliminary scale, the scale was reduced from 48 to 17 items using classical and item response theory. The unidimensional scale now comprises five domains: 1) use of health information; 2) clarifying personal priorities; 3) communicating with others; 4) negotiating roles and taking control; and 5) deciding and taking action.

Update

At this point, we are very excited to be validating the Effective Consumer Scale in a number of countries. Groups in Argentina, Ireland, Norway, Sweden, and Romania are also validating the scale (in other languages) and gathering baseline data.

***Seeking your input***

We are also interested in identifying an RCT in which we could use the scale. If you are planning a trial, please contact Tamara Rader (trader [at] uottawa.ca)
