iCanCope With Post-Operative Pain (iCanCope PostOp)

This will be centrally tracked by the clinical research project coordinator (CRPC).

Any issues or difficulties encountered during implementation of the intervention, control strategy, or outcome measures will be tracked throughout the study by the CRPC.

Participants in the intervention arm will complete the Acceptability e-scale (AES) post-intervention. In addition, a subset of participants from the intervention group will be offered to participate in a qualitative feedback interview to further explore acceptability and satisfaction of the intervention.

Google Analytics will track patterns of app and website usage.

Measured using the short form Brief Pain Inventory (BPI), a 15-item tool that measures pain intensity and impact on functioning.

Measured with the PROMIS Pediatric Sleep Disturbance - Short Form 4a, a 4-item measure for assessing sleep disturbance. Each item asks the child receiving care to rate the severity of his or her sleep disturbance during the past 7 days. Each item on the measure is rated on a 5-point scale (1=never; 2=rarely; 3=sometimes; 4=often; and 5=always) with a range in score from 8 to 40 with higher scores indicating greater severity of sleep disturbance.

Measured using the PROMIS Pediatric Mobility SF, an 8-item questionnaire designed to investigate the general impact that the patient's lower limbs mobility had on their daily activity tasks (such as playing with friends or walking up the stairs). Each item is scored from 1 (not able to do it0 to 5 (with no trouble). As per PROMIS guidelines, raw score is calculated as the sum of each item score. Scale score was calculated from raw score using the PROMIS conversion table.

Measured using the PROMIS Pediatric Depressive Symptoms SF, an 8-item questionnaire designed to determine how often one is experiencing specific depressive symptoms in the past 7 days. Each item on the measure is rated on a 5-point scale (1=never; 2=almost never; 3=sometimes; 4=often; and 5=almost always) with a range in score from 14 to 70 with higher scores indicating greater severity of depression.

Measured using the PROMIS Anxiety SF, the 13-item questionnaire that assesses the pure domain of anxiety in children and adolescents. Each item asks the child receiving care to rate the severity of his or her anxiety during the past 7 days. Each item on the measure is rated on a 5-point scale (1=never; 2=almost never; 3=sometimes; 4=often; and 5=almost always) with a range in score from 13 to 65 with higher scores indicating greater severity of anxiety.

Measured using the Patients Global Impression of Change (PGIC), that reflects a patient's belief about the efficacy of treatment. Patients rate their change as "very much improved," "much improved," "minimally improved," "no change," "minimally worse," "much worse," or "very much worse."

Measured using the Child Surgical Worries Questionnaire, a 27-item self-report measure assessing worries caused by hospitalization and surgery. Patients rate how worried they are about various situations, using the following scale: 0=not at all worried, 1=a little worried, 2=moderately worried, 3=considerably worried, 4=extremely worried.

Measured using the Pain Catastrophizing Scale - Parent (PCS-P), a 13-item questionnaire concerning the different thoughts and feelings parents may have when their child experiences pain. Items assessing catastrophic thoughts and feelings about their child's pain use a Likert-type 5-point scale (0 = "not at all" to 4 = "extremely"). The PCS-P yields three subscale scores for rumination, magnification, and helplessness, as well as a total score ranging from 0 to 52.
