Empowering Patients to Participate in Health Care Decisions

Health-related quality of life

What is the effect of interactive patient education in supervised study groups on participants' health-related quality of life (measured by change in scores in EQ-5D from baseline to 6 months after baseline). The EQ-5D-3L descriptive system comprises the following five dimensions: mobility, self-care, usual activities, pain/discomfort and anxiety/depression. Each dimension has 3 levels: no problems, some problems, and extreme problems. The patient is asked to indicate his/her health state by ticking the box next to the most appropriate statement in each of the five dimensions. This decision results into a 1-digit number that expresses the level selected for that dimension. The digits for the five dimensions can be combined into a 5-digit number that describes the patient's health state.

Sense of coherence (SOC)

What is the effect of interactive patient education in supervised study groups on the participants' sense of coherence (measured by changes in scores in SOC-13 scale in Swedish9 from baseline to 3 months after baseline). Antonovsky developed the 29 item Orientation to Life Questionnaire to measure the sense of coherence, having 11 items measuring comprehensibility, 10 items measuring manageability, and 8 items measuring meaningfulness. The response alternatives are a semantic scale of 1 point to 7 points. The questionnaire yields a summed score with a range from 29 to 203. A shorter version of 13 questions of the original form was developed by Antonovsky, where the score ranges between 13 and 91 points,

Health literacy

What is the effect of interactive patient education in supervised study groups on participants' health literacy (measured by change in scores in HLS-EU-Q16-SE from baseline to 3 months after baseline).

More specifically, the 16 items include perceived skills for understanding health information, where to seek consultation and health information on prevention, early detection, and health care, health warnings, advice given by family and friends, how to seek a second opinion, and how to apply advice given by care providers. Response options include "very easy," "easy," "difficult," and "very difficult."
