Vales+Tú: a cluster-randomized pilot study to reduce workplace injuries among US Latino day laborers

Health Promot Int. 2022 Dec 1;37(6):daac163. doi: 10.1093/heapro/daac163.

Abstract

Latino day laborers (LDL) are a vulnerable population of workers facing considerable risk for occupational injury. Under the guidance of our Community Advisory Board, we developed and tested the feasibility, acceptability and preliminary effects of Vales+Tú (You Are Worth More), a workplace injury risk-reduction program implemented by promotores on street-corners where LDL seek employment. The program was informed by theoretical perspectives emphasizing individual and group agency and self-determination. A pilot three-arm cluster-randomized community trial was conducted among 75 LDL. The intervention arms consisted of an individualized Brief Motivational Interview, a Group Problem Solving activity and a standard of care control (OSHA safety cards). We met our study goal of 25 LDL per intervention arm, and contacted 88% of participants post intervention. Participants evaluated the interventions favorably. At post-test, the Brief Motivational Interview group reported significant reductions in exposure to workplace hazards and increases in risk-reduction practices. The Group Problem Solving participants showed significant reductions in exposure to hazards (t-test -4.16, p < 0.001). Both intervention groups increased their reliance on corner peers, a measure of social support. Standard of care participants increased in self-efficacy to work safely. Overall, the only significant different between the three study conditions was in self-efficacy. These findings provide evidence of the feasibility and acceptability of Vales+Tú and show preliminary program efficacy. A large-scale replication trial will permit a more formal modeling of the study findings. Clinical Trial Registration (ClinicalTrials.gov): NCT04378348.

Plain language summary

This pilot-randomized trial tested the feasibility and initial efficacy of an injury risk-reduction program among Latino day laborers (LDL). The study tested two alternative interventions consisting of a Brief Motivational Interview (Individual) and a Group Problem Solving (Group) conditions that were compared with a Standard-of-Care control group receiving safety cards. We then tested the extent to which the study conditions reduced exposure to workplace hazards and increased safety practices at work. Results indicate that intervening at day labor corners is a feasible intervention strategy acceptable to these immigrant workers. Initial results also indicate that there were multiple within-group significant differences in risk reduction, mostly in the individual condition, and that there was one significant between-group difference in safety self-efficacy at post-test. A larger more rigorous trial can further test the stability of these results and determine the extent to which these intervention approaches can reduce the risk for injury that LDL confront at work.
