PainSquad+: A Smartphone App to Support Real-time Pain Management for Adolescents With Cancer

Study Overview
=================
Brief Summary
-----------------
Adolescents with cancer (AWC) are in a unique developmental stage that may mean pain characteristics, the impact of pain, and pain treatment outcomes are different in adolescents compared to children and adults. In response, we will develop and test the PainSquad+ pain management smartphone app. First, we will conduct usability testing to refine PainSquad+ so that it is useable, acceptable and understandable for AWC. Secondly we will: (a) test the feasibility of conducting a large-scale PainSquad+ experiment and (b) begin to examine how effective PainSquad+ is at helping adolescents manage pain. We hope that once developed and tested for effectiveness, PainSquad+ will improve pain treatment and ultimately quality of life in AWC.

Detailed Description
-----------------
Using a conservative estimate of 7 adolescents per cycle and 3 testing cycles, 21 adolescents will take part in usability testing of the PainSquad+ prototype. Recruitment will be conducted in a single hematology/oncology division of a metropolitan and university-affiliated pediatric tertiary care center in Toronto, Canada. This site hosts one of the largest cancer programs in North America, with approximately 350 new diagnoses each year. Based on our previous research at this site, 72 ± 4% (M ± SD; range = 67-75%) of eligible AWC agreed to participate in similar studies (unpublished data). Convenience sampling will be used to recruit eligible individuals. The testing procedures will commence after eligibility is assessed, informed consent is obtained, and demographic and baseline outcome data are collected. Inclusion criteria will be: (a) aged 12-18 years, (b) able to speak and read English, (c) actively undergoing cancer treatment on an in- or out-patient basis, (d) being at least 3 months from diagnosis and (d) having self-reported pain of any intensity in the week immediately prior to recruitment. Exclusion criteria will be: (a) one or more major co-morbid (medical or psychiatric) conditions that would preclude use of a smartphone, and (b) palliative/end-of-life patients.

Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Accrual and attrition rates | The Cancer Pain Management App Recruitment Log has been designed to record data related to the number of eligible adolescents per recruitment day, reasons for ineligibility, and reasons for nonparticipation. The Cancer Pain Management App Activity Log has been designed to record data on attrition (occurrence/reasons for attrition), as well as technical difficulties, adherence and outcome measure completion. | 12 months | 
| Technical difficulties | The occurrence and description of technical problems will be recorded on the Cancer Pain Management App Activity Log. | 12 months | 
| Acceptability | The Acceptability E-Scale (AES) ascertains perceptions related to how helpful, difficult, and enjoyable e-based programs are to use, how understandable questions are, and how acceptable the time invested in reporting was (Wu, Johnson, Schepp, & Berry, 2011). For the purpose of the present study, the wording of the AES will be slightly modified. Specifically, the words computer program will be changed to app and open-ended questions regarding study acceptability will be added. | 12 months | 
| Adherence | Measured as the percentage of pain reports received on the secure server. An RA will sign onto the server and extract data logged by AWC on Day 29 to calculate adherence (100% when 28/28 morning and evening reports are completed). These data will be recorded on the Cancer Pain Management App Activity Log. | 12 months | 
| Outcome measure feasibility | Measured as the percentage of completed questionnaires at baseline and study completion. An RA will sign onto the server and extract data logged by AWC on Day 29 to calculate the percentage of completed questionnaires (100% when all questionnaires are completed). These data will be recorded on the Cancer Pain Management App Activity Log. | 12 months | 
| Pain intensity | Measured using the pain intensity items (current pain intensity and worst, average, and least pain intensity in the previous week) of the Brief Pain Inventory (BPI). The BPI is considered the standard for clinical and research use in cancer patients (Mathias et al., 2011). Each item is rated numerically from 0-10. Individual scores on each of the 4 items may be summed and to provide a composite pain intensity score. Individual and summary scores will be used in our analyses. Validity and reliability have been well-established in adults with cancer and the intensity sub-scale has been used successfully in AWC (Ameringer, 2010). | 12 months | 
| Pain interference | The Patient Reported Outcomes Measurement Information System Pediatric (PROMIS) Pain Interference Short-form Scale is an 8-item scale describing how pain restricts daily activities related to physical, psychological, and social functioning, as well as sleep, school, and enjoyment of life. Each item is scored on a 5-point Likert response scale and totaling the scores generates a summary score, which will be used in our analyses. Construct validity has been established in AWC (Hinds et al., 2013). | 12 months | 
| Health-related quality of life (HRQL) | The Pediatric Quality of Life Inventory (PedsQL) 4.0 is a 23-item generic HRQL scale not specific to pain. It is comprised of physical, emotional, social and school functioning subscales with each subscale containing 5 to 8 items. PedsQL4.0 is a reliable and valid measure of HRQL in AWC (Varni, Burwinkle, Katz, Meeske, & Dickinson, 2002). We will use age-appropriate versions of PedsQL4.0 (i.e., appropriate item wording for 12 and 13-18 year olds). Total and subscale scores will be used in analyses. | 12 months | 
| Self-efficacy | The Sherer's General Self-Efficacy Scale (GSES) is a 17-item scale that measures general belief in personal competence and has been used in children as young as 10 years old. Each item is scored on a 5-point Likert scale. Item scores are summed to provide an overall self-efficacy score to be used in analyses. The psychometric properties of the measure have been demonstrated in AWC (Hinds et al., 2000). | 12 months | 
| Healthcare utilization | Healthcare utilization related to pain will be examined as the number of visits/calls to primary care provider, emergency room visits, oncology clinic visits and hospitalizations (i.e., bed days of care). RN calls will not be included in healthcare utilization analyses. Data will be collected using adolescent self-report and medical health records (by site specific RAs at end of study). | 12 months |
