Arms and Interventions

| Participant Group/Arm | Intervention/Treatment |
| --- | --- |
| Experimental: individual (Brief Motivational Intervention)<br> | Behavioral: individual -Brief Motivational Intervention (BMI)<br>* A baseline survey will be administered prior to the session.Sessions will be initiated by exploring working conditions and psychosocial factors that may influence risk for work related injuries. If the LDL is motivated to change the target behavior, a 'change plan' will be developed which involves identifying reasons for change, goals in making change, specific actions and timelines, and others who may help the person change. The final step will be the development of a personal safety plan to reduce work place risks and a discussion of the following topics: (a) how they will know if their plan is successful, (b) potential obstacles, and (c) what the worker can do if the plan does not work. Finally,each worker will be asked to write and sign a personal pledge (Mi Promesa) to implement his own safety plan.Follow-up surveys will be conducted 4 weeks after the baseline survey.<br>|
| Experimental: Group (Group Problem Solving)<br> | Behavioral: Group (Group Problem Solving)<br>* Participants will be administered a baseline survey prior to session. The GPS intervention consists of a discussion between 2-5 LDLs and a trained group facilitator. The sessions will last 30-45 minutes and are intended to encourage and support Latino day laborers (LDL) to act to reduce work-related hazards and promote worksite safety. The intervention combines four participatory and group problem solving activities to engage in collaborative learning: an icebreaker, the risk identification, action planning, and Nuestra Promesa (Our Pledge). The last activity requires LDL to select a risk reduction behavior and then to fill out and sign a card detailing a pledge to implement a safety plan. Follow up surveys will be conducted four weeks post intervention, to assess participants' change in attitudes, beliefs, and risk reducing behavior and their implementation or their safety plan.<br>|
| Placebo Comparator: Standard of Care<br> | Behavioral: Standard of Care (OSHA 10 Safety Cards)<br>* Participant will be administered a baseline survey prior to the session.Participants in this standard of care control group will receive four wallet size cards with information about risk reduction strategies to deal with the four hazards responsible for most workplace fatalities in Texas: falls, struck by, heat exposure and cuts. The laminated cards are adapted from OSHA's website publicly available materials in Spanish for workers with limited literacy.<br>|

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Work Hazard Exposure as Assessed by a Survey | Total score on the work hazard exposure survey ranges from 1 - 4, with a higher score indicating greater work hazard exposures. The data are reported as score at post-intervention minus score at baseline. | Baseline, 4 weeks post intervention | 
| Change in Work Conditions as Assessed by a Survey | Total score on the work conditions survey ranges from 1 - 4, with a higher score indicating greater adverse work conditions. The data are reported as score at post-intervention minus score at baseline. | Baseline, 4 weeks post intervention | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Change in Safety Practices as Assessed by a Survey | The score for each of the 22 safety practices items ranged from 1-4, with a higher score indicating greater safety practice. The total score for the complete scale consisting of all 22 items is the average of items responded to and also ranged from 1-4. Separate scores for each subscale were computed similarly. The first subscale consisted of eight items; the second consisted of four items, and the third consisted of three items--the score for each subscale ranged from 1-4, with a higher score indicating greater safety practice. There were seven original items that were not associated with the subscales derived from the factor analyses. The data are reported as scores at post-intervention minus scores at baseline. | Baseline, 4 weeks post intervention | 
| Number of Participants That Implemented the Safety Plan as Assessed by a Survey | Participants were asked if they implemented the safety plan and they were asked to answer as yes, no or partially | 4 weeks post intervention |
