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

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research at this site, 72 ± 4% (M ± SD; range = 67-75%) of eligible AWC agreed to participate in similar studies (unpublished data).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.
