Louisiana trucking companies' implementation of workplace health promotion programs: Explanatory sequential mixed method case study.

BACKGROUND: Trucking companies may be key partners for workplace health promotion programs to improve heavy and tractor-trailer drivers' health and wellbeing. OBJECTIVE: To identify barriers and facilitators to implementing workplace health promotion programs among Louisiana trucking companies' leadership and staff. METHODS: A case study approach following an explanatory sequential mixed method research design was used. A quantitative survey, based on the Theoretical Domains Framework (TDF), was adapted and distributed online to a convenience sample. Survey respondents were recruited for an interview to gain additional insight on multi-level barriers to implementing workplace health promotion programs. Quantitative data was analyzed using descriptive statistics to describe barriers and facilitators following TDF constructs. Qualitative data were independently coded among two researchers following the TDF and the Consolidated Framework for Implementation Research (CFIR) to determine themes. RESULTS: Eleven workplace leaders or staff took the survey. Two engaged in a follow-up interview. Regarding the quantitative results, most (82%) believed workplace health promotion programs would save their company money, although were not offering them. No TDF constructs were indicated as barriers given mixed results; however, several were facilitators: Social/Professional Role and Identity; Emotion; Action Planning; Knowledge; Motivation and Goals; and Beliefs about Consequences. Qualitative results captured several Inner (e.g., time, money) and Outer Setting contextual (e.g., truckers' needs and resources) factors considered important to trucking companies' implementation of health promotion programs. CONCLUSION: Results suggest leadership and staff of Louisiana trucking companies value workplace health promotion programs, although are challenged by limited resources and the broader trucking environment.
