*2.3. PUSH Training*

The PUSH training is comprised of topics from the NIOSH Youth@Work: Talking Safety curriculum and two evidence-based curricula on health promotion [22,23], with additional topics addressing protection from workplace hazards, promotion of health and well-being, and workplace communication [12,16]. It was delivered through an online training format that had been used to teach skills using behavioral education principles among workers in different industries [14,24–26]. This format has also been effective in disseminating information on occupational health and safety for diverse worker groups [27–29].

Content experts in the field of occupational health and safety, and health promotion developed the original PUSH training. The videos and content used in the training were pilot tested with young workers on the MTurk platform as a part of the development process. Questionnaire items (e.g., demographics, work history, and likeability/acceptability) had been used previously by researchers in other studies with young workers [12,16]. The team used validated measures to assess general health, health behaviors, and job content [12,16].

PUSH is a self-paced online training that uses videos and real-life examples to teach young workers about safety, communication, and health. Participants were directed to a series of content screens with videos by an icon-based navigation system. Multiple choice questions were followed by brief videos that needed to be correctly answered to progress through the training [12]. Additional details in regard to the study are available at a separate study by the same co-author [12].
