Home-Based Intervention for Chronic Pain in Adults With Sickle Cell Disease

For daily measures, self-reported pain ratings will be assessed with the Numerical Pain Rating Scale (NPRS). On the NPRS, pain intensity levels range from 0 to 10 (0 = no pain and 10 = worst pain). Lower pain ratings correlate with better outcome.

Daily Pain Diary responses were intermittent and can only be aggregated during time period 1 (days 1-28) and time period 2 (days 29-56). Diaries were not administered at day 0.

For baseline and monthly measurements, self-reported pain ratings were assessed with the Pain Intensity subscale of the Chronic Pain Grade Questionnaire. On the Chronic Pain Grade Questionnaire, pain intensity levels range from 0-100. Lower pain ratings correlate with better outcome.

Minutes of daily program use may range from 2 minutes to 48 minutes or more. The investigator hypothesizes that higher usage will correlate with a better outcome.

Because of intermittent usage patterns, self-reported program use was aggregated during time period 1 (days 1-28) and time period 2 (days 29-56).

Throughout the 8-week treatment period, device usage duration may range from 0 to 7 days each week. The investigator hypothesizes that higher usage will correlate with a better outcome.

Assessed by the number of features utilized when using the VRdevice. The number of features utilized may be 1 or 2 . The investigator hypothesizes that use of a higher number of features will correlate with a better outcome.

Assessed by completion rates: the number of modules completed weekly. Rates may range from 0 to 7 modules completed each week. The investigator hypothesizes that completion of a higher number of modules weekly will correlate with a better outcome.

Assessed by participant completion of survey measures at repeated timepoints (baseline, week 4, week 8, and week 12). The investigator hypothesizes that higher study retention will correlate with a better outcome.

Assessed by participant completion of daily diaries across 8 weeks of treatment (days 1-56). The investigator hypothesizes that higher study retention will correlate with a better outcome.

Assessed, once at the end of the program, via individual qualitative interviews or focus group sessions. Participants will be asked to evaluate the program by responding to the four items listed below, using a Likert scale (strongly agree, somewhat agree, somewhat disagree, strongly disagree with possible score range 1-4) for the first three items and 1-10 (with 10 being definitely would recommend) for the fourth item.• The VR program was easy to use.• I enjoyed using the VR program.• The content in the VR program helped me cope with my pain.• On a scale of 1-10, how likely are you to recommend the VR program to someone else at this time? The investigator hypothesizes that responses of strongly agree and higher scores will correlate with a better outcome.

Assessed once at the end of the program, via individual qualitative interviews or focus group sessions.

Participants choosing the highest score for each of the four items listed will be counted.

Higher number correlates with a better outcome.

Assessed by monitoring participants for the number of adverse events. Fewer adverse events correlate with a better outcome.

Assessed by the Chronic Pain Acceptance Questionnaire (CPAQ-8) which measures acceptance of chronic pain. Items are scored on a scale from 0 to 6 (never true to always true), and higher scores (total possible scores range from 0 to 48) indicate higher levels of acceptance (better outcome).

Items are scored on a 10-point Likert-type scale from 1 (very uncertain) to 10 (very certain), with a minimum total score of 22 and a maximum total score of 220. Higher scores indicate a better outcome.

Items are scored on a scale from 1 (not at all) to 5 (very much, constantly), with a minimum total score of 32 and a maximum total score of 160. Higher scores indicate a better outcome.

Assessed by using the Pain Catastrophizing Scale (PCS-13) which measures thoughts and feelings when pain is experienced. Items are scored on a scale from 0 to 4 (not at all to all the time), and higher scores (scores range from 0 to 52) indicate a higher degree of catastrophizing (worse outcome).

Assessed by using the BRIEF Health Literacy Screening Tool which measures the amount of help needed in healthcare situations. Items are scored on a scale from 1 to 5 (always to never and not at all to extremely), and higher total scores (scores range from 4 to 20) indicate greater health literacy (better outcome).

Behavior Rating Inventory of Executive Function (BRIEF-A) which measures adult executive functioning/self-regulation. Items are scored on a scale from 1 to 7 (never a problem to always a problem) and higher total scores (scores range from 34 to 238) indicate more symptoms of executive dysfunction (worse outcome).

Assessed by using PROMIS Emotional Distress - Anxiety (Anxiety 8a - Adult v1.0), which measures self-reported fear, anxious misery, hyperarousal, and somatic symptoms related to arousal. Items are scored on a 5-point Likert scale ranging from 1 (never) to 5 (always) and the total raw score (minimum total score of 8 and maximum total score of 40) is rescaled into a standardized T-score. The standardized T-score, with a minimum total score of 37.1 and a maximum total score of 83.1, has a mean of 50 and a standard deviation of 10. Higher T-scores indicate a worse outcome.

Assessed by using PROMIS Emotional Distress - Depression (Depression 8a - Adult v1.0), which measures self-reported negative mood, views of self, social cognition, and decreased positive affect and engagement. Items are scored on a 5-point Likert scale ranging from 1 (never) to 5 (always) and the total raw score (minimum total score of 8 and maximum total score of 40) is rescaled into a standardized T-score. The standardized T-score, with a minimum total score of 38.2 and a maximum total score of 81.3, has a mean of 50 and a standard deviation of 10. Higher T-scores indicate a worse outcome.
