Chronic Low Back Pain Graded - Exposure Psychoeducation Intervention

The Numeric Rating Scale (NRS) measures pain intensity measured via 0-10 numeric rating scale.

0 = No Pain - 10 = Worst Possible Pain Range of scores: 0-10

Present Pain Intensity (PPI) assesses present pain intensity on a scale of 0 (no pain) to 5 (excruciating)

Pain Rating Index (PRI) is assessed by 15 questions assessing pain in the sensory and affective dimensions.

Items rate from 0 (none) to 3 (severe) on degree to which the words apply to pain.

Score Range: 0-45

Pain Chronicity is assessed by the Graded Chronic Pain Scale (GCPS). The GCPS is 7 questions with 3 sub-scales (Characteristic pain intensity, disability score, and disability points).

Scoring:

Characteristic Pain Intensity: is a 0 to 100 score derived from Questions 1 through 3: Mean (Pain Right Now, Worst Pain, Average Pain) X 10.

Disability Score: is 0 to 100 score derived from Questions 4 through 6: Mean (Daily Activities, Social Activities, Work Activities) X 10 Disability Points: Add the indicated points for Disability Days (Question 7) and for Disability Score (0-6).

Items rate from 0 to 10 with 0 referencing no pain/interference/change and 10 referencing pain as bad as could be/unable to carry out any activities/extreme change.

Daily pain monitoring defined as daily pain intensity and daily pain interference monitoring is two questions asked daily on a 10 point scale assessing daily pain and how much pain had interfered with day to day activities.

Pain: Over the past 24 hours, how would you rate your back pain on average? (0=No Pain; 10=Worst Imaginable Pain)

Interference: Over the past 24 hours, how much did pain interfere with your day-to-day activities? (0=No Interference; 10 = A great deal of interference)"

Immersive Tendencies are assessed by the Immersive Tendencies Questionnaire (ITQ). This is an 18-item survey. Item responses use a 7 point Likert scale. Subscales include: focus, involvement, emotions, and play. Each subscale is scored by summing items. A total score is scored by summing all items.

Range of total score: 18-126 Focus range of scores: 5-35 Involvement range of scores: 5-35 Emotions range of scores: 4-28 Play range of scores: 3-21 Higher scores indicate higher immersive tendencies overall and in each sub-scale.

Tellegen Absorption Scale is a 34-item multi-dimensional measure that assesses imaginative involvement and the tendency to become mentally absorbed in everyday activities. Item responses are on a 5-point Likert scale. Items are summed to score.

Range of scores: 0-136. Higher scores indicate greater levels of absorption.

Patient treatment evaluation is assessed by Treatment Evaluation Inventory. This is a 9 item scale with a 5-point Likert responses for each question. The items are scored by summing all items.

Range of scores: 9-45. A higher score indicates greater acceptance of treatment.

Patient treatment evaluation is assessed by semi-structured interviewing. Qualitative feedback from participant experience will be assessed by thematic analyses.

The daily intervention feedback questions are 7 items that assess the individuals feelings and experiences during that daily intervention session.

0-10 Likert scale

Each item is it's own scale.

Higher scores indicate more enjoyment/usefulness/demand/awareness/concern/mood.

The Usefulness, Satisfaction, and Ease of Use Questionnaire (USE, Lund, 2001) measures the subjective usability of a product or service. It is a 30-item survey that examines four dimensions of usability: usefulness, ease of use, ease of learning, and satisfaction. This metric can be applied to various scenarios of usability assessment because it is non-proprietary and technology-agnostic. is a 30 item survey.

Each item is presented on a 7-point Likert scale from strongly disagree = 1 to strongly agree. = 7

Each subscale is calculated by averaging all items in subscale. Usefulness: items 1-8 Ease of use: items 9-19 Ease of Learning: items 20-23 Satisfaction: items 24-30

Range of scores for each subscale: 1-7 Scoring Interpretation: Higher score indicates greater usefulness, satisfaction, and ease of use.

Patient treatment evaluation is assessed by the Patient Global Impression of Change. This is a one item 7 point Likert item assessing improvement of the participants overall status.

Item responses:

1 = very much improved, 2 = much improved, 3 = minimally improved, 4 = no change, 5 = minimally worse, 6 = much worse, and 7 = very much worse

Video game preferences will be assessed by the BrainHex. The BrainHex provides a tool for designing gameplay and understanding motivations for play.
