*2.2. Survey Instruments*

Questionnaires were used to collect information at three time points: immediately prior to completing the training (Baseline), immediately after completing the training (Post-training), and 3-months after the training (Follow-up). Participants completed the questionnaire and the training online after they received a link to the materials either through their email or through the MTurk platform.

At baseline, participants provided demographic information along with information on work history and previous safety trainings. Health and safety knowledge was assessed immediately before and after the training by twenty-one multiple choice questions that were categorized into topics: hazard identification (e.g., "Sarah works at a bakery where her responsibilities are to take orders from customers, make sandwiches, and tidy up. Sometimes the morning rush is so overwhelming that she gets very distracted. What type of hazard is a distraction?"), control selection (e.g., "What is the least effective way of controlling a hazard?"), communication including workers' rights, health behaviors, and safety questions, (e.g., "Regarding workplace violence, it is your responsibility to . . . ").

At the three-month follow-up, participants answered survey questionnaires about their current job, whether they liked the training and if they changed their behavior as a result of completing the training. Along with this, participants answered twenty-one knowledge questions and completed items addressing their general health and other health behaviors. Open-ended questions were used to assess the participants' reaction to the training. Likeability and acceptability were assessed using the question "Did you like the PUSH training? Why or Why not?" and the impact of the training on behavior change was assessed through the question "Did you see or experience any behaviors over the last three months that you felt prepared to handle because of the PUSH training program? If so, please explain."
