A protocol for a single-arm, mixed methods, hybrid effectiveness-implementation trial evaluating the IMplementation of Physical Activity for Children and adolescents on Treatment (IMPACT) for cancer diagnoses in Alberta
Bibliographic record
Abstract
Background: Physical activity (PA) is feasible, safe, beneficial, and recommended for pediatric cancer patients, yet PA levels are low due to numerous barriers. Delivering PA by videoconference may address selected barriers. Few have explored this delivery modality; in response the IMplementation of Physical Activity for Children and adolescents on Treatment (IMPACT) intervention (a PA intervention) was developed. Methods: The IMPACT intervention is delivered by videoconference and is being evaluated in a single-arm, mixed methods, type II hybrid effectiveness-implementation trial. Pediatric cancer and blood disorder patients diagnosed between 5-18 years old are eligible. Participants are offered tailored PA sessions 3 times/week for 15-45 minutes/session over 12-weeks. The co-primary aims of this trial are to: (1) assess the effectiveness of the videoconference-delivered PA intervention on participant’s objective PA (primary effectiveness outcome) and secondary effectiveness outcomes of participant- and caregiver-reported outcomes, and physical fitness outcomes at baseline, post-intervention, and 6 and 12-month follow-ups, and (2) assess implementation of the PA intervention and trial through evaluating recruitment, indices of feasibility, delivery time, expertise, cost, fidelity of intervention delivery, and adverse events. Interviews are conducted post-intervention with participants and caregivers to explore perceptions of and experiences with the intervention. Implementation data are tracked throughout and quality improvement cycles occur every 6 months. Trial data are analyzed at pre-specified time-points. Conclusions: This work will provide insights into the effects and factors influencing PA intervention implementation. Findings may offer support for videoconference delivery as a strategy to ensure more pediatric patients can access and benefit from PA.

Full frame machine prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. The Gemma side is a direct model label for every work in the frame, read from the title-only record. The Codex side is a classifier learned from the 10,348 direct Codex labels and calibrated to design-weighted sample rates; fields without enough sample support carry no Codex call. Candidate is the union of the two sides; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one source (direct Gemma or distilled Codex), not a consensus.
