Pilot Testing A Theory-Driven Self-Management Intervention for Chronic Musculoskeletal Pain

The Brief Pain Inventory-short form (BPI-sf) questionnaire includes assessment of pain location and multiple aspects of severity of pain, numbness, tingling, and stiffness, including worst, least, average pain, and present, as well as the interference with daily activities. The Brief Pain Inventory-short form (BPI-sf) has a total score ranging from 0 to 10 with higher scores indicating more pain.

The Roland Morris Disability Questionnaire (RMDQ), 24-item measure, was used to assess the impact of back pain on their daily functioning. The score ranged from 0 (no disability) to 24 (maximum disability).

The Oswestry Disability Index (ODI) was used to measure a participants impairment and quality of life on 10 items with 0-5 point scales. Each section is scored on a 0-5 scale, 5 representing the greatest disability. The index is calculated by dividing the summed score by the total possible score, which is then multiplied by 100 and expressed as a percentage. Thus, for every question not answered, the denominator is reduced by 5; a lower score indicates less disability.

The WHO Quality of Life-BREF (WHOQOL-BREF), used to measure quality of life. The WHOQOL-BREF, is self-administered, and measures the following broad domains: physical health, psychological health, social relationships, and environment. Each individual item of the WHOQoL is scored from 1 to 5 on a response scale, which is stipulated as a five-point ordinal scale. The measure is calculated by summing the point values for the questions corresponding to each domain and then transforming the scores to a 0-100 point interval. The first two questions of the WHOQOL-BREF do not correspond to a domain, but are meant to provide a global assessment of quality of life. Higher scores in each of the domains correspond to greater perceived quality of life.

The participants will be assessed using a 12-item Treatment Satisfaction Questionnaire, with 4 items with scored for treatment difficulty 1 (extremely difficult) - 5 (not difficult), 7 single-choice questions assessing satisfaction and effectiveness of treatment and 3 open-ended questions assessing satisfaction and effectiveness of treatment. Maximum score of 36; A higher score indicates more satisfaction from the treatment.

It is measured by Fear-avoidance beliefs questionnaire (FABQ) that focuses on participants beliefs about how physical activity and work affect their pain. The questionnaire consists of 16 items in which a participant rates their agreement with each statement on a 7-point Likert scale. Where 0= completely disagree, 6=completely agree. Maximum score of 96; A higher score indicates more strongly held fear-avoidance beliefs. The first 5 questions pertain to physical activity while the remaining 11 pertain to work. The Physical Activity subscale range 0-24 is the sum of items 2-5; the Work subscale, range 0-42 is the sum of items 6, 7, 9-12 and 15.

Placebo effects will be measured via Healing Encounters and Attitudes Lists (HEAL) Treatment Expectation questionnaire. HEAL is an item bank comprised of 6 domains. The Treatment Expectancy questionnaire consists of 6 items on a 5 point scale - not at all to very much. Score range of 6-30 with higher score indicating better outcome.

The PCS was included to detect exaggerated and negative interpretations of pain. It is a self-report scale that consists of 13 items. Participants were asked to reflect on past painful experiences and to indicate to which degree he/she experienced symptoms such as helplessness or rumination when feeling pain.This is a 0-4 Likert scale (score sum 0-52) with responses ranging from "not at all" to "all the time," and high scores indicate stronger catastrophizing.

Pre and post treatment positive outlook effects will be measured via Healing Encounters and Attitudes Lists (HEAL) Positive Outlook scale. The participants will be assessed using a 6-item questionnaire, scored for outlook on life 1 (not at all) - 5 (very much). Score range of 6- 30; A higher score indicates more positive outlook and satisfaction with ones life.
