“…Finally, we note that overall, fidelity in this study was high (as is expected in an efficacy study), but that where facilitators were unable to implement all program activities, time emerged as a key barrier (see Supplemental Material). Time is also a commonly reported barrier in past implementation work on other Fourth R programs (Crooks, Chiodo, Zwarych, Hughes, & Wolfe, 2008; Exner-Cortens, Spiric, Crooks, Syeda, & Wells, 2018b). Thus, as part of planning for HRP implementation, we urge school psychologists to examine how the time needs of the program might best fit within the school environment (e.g., deciding when and how often to offer the program, leaving time for extra sessions at the end) and to be planful about adaptations to the program that arise due to time constraints.…”
