COMPRENDO (ChildhOod Malignancy Peer Research NavigatiOn) is a multi-site randomized clinical trial (RCT) that uses a Hybrid Type 1 design, to test the effects of a clinical intervention on patient-level outcomes, while exploring multilevel implementation factors that can inform real-world setting implementation. This study will test the impact of COMPRENDO, a peer-navigation intervention, vs. usual care on accrual to childhood cancer therapeutic clinical trials and parental informed consent outcomes. COMPRENDO will be delivered by trained peer navigators in 4 visits. A mixed methods (surveys, individual interviews) implementation evaluation will examine implementation factors that can inform the use of peer navigation in clinical practice, integrating data from clinicians, navigators, administrators, and parents pre and post the RCT.

Official Title

Multisite Implementation of COMPRENDO (ChildhOod Malignancy Peer REsearch NavigatiOn) to Improve Participation of Hispanic Children in Cancer Clinical Trials


Aim 1:

Test the effectiveness of COMPRENDO vs. usual care to increase clinical trial accrual in a multisite RCT.

Aim 2:

Determine the impact of COMPRENDO vs. usual care on parental outcomes (informed consent, comprehension, voluntariness, decision-making self-efficacy, satisfaction with informed consent and decisional regret).

Aim 3:

Evaluate multisite implementation of COMPRENDO, focusing on acceptability, feasibility, and fidelity. We will use mixed methods with a minimum of 50 stakeholders: 22 clinicians, (17 oncologists, 3 psychologists, 2 social workers), 4 navigators, 4 administrators and 20 parents to identify implementation factors.

Within each site, eligible participants will be randomized 1:1 to the intervention vs. usual care (informed consent discussion with the oncologist only), resulting in ≈200 participants randomized to each arm.
