Patient-Reported Outcomes Measurement Information System 29

Change in 8 health-related quality of life domains as measured by the PROMIS 29. PROMIS-29 is a generic patient reported outcome measure, which includes four items from each of the seven PROMIS domains (physical function, depression, anxiety, fatigue, sleep disturbance, and ability to participate in social roles and activities, pain interference) and a single item on pain intensity. Each item has five response options (values 1 to 5), except for the pain intensity item which has eleven response options (values 0 to 10). A total raw score is computed for each domain as the sum of the response to each question within the domain, leading to seven domain scores, each from 4 to 20.

Time frame: Change from week start of MBSR intervention (week 0) to end of intervention (week 8), 3-month follow-up (week 21)

French-Canadian Chronic Pain Self-Efficacy Scale

The French-Canadian Chronic Pain Self-Efficacy Scale (Lacasse et al., 2015) is a 6-item scale that measures an individual's confidence in his/her ability to manage chronic pain in general and pain-related symptoms. Items are rated on a 10-point Likert scale ranging from 1 = not at all confident to 10 = entirely confident. Score range is 6-60 with higher scores reflecting greater chronic pain self-efficacy.
