Process evaluation of a multifaceted health program aiming to improve physical activity levels and dietary patterns among construction workers.
OBJECTIVE
To evaluate the process of a health promotion program, aiming to improve physical activity levels and diet among construction workers.


METHODS
The process evaluation was conducted after the RE-AIM framework for the evaluation of the public health impact of health promotion interventions. Effectiveness was assessed on motivational stage-of-change, self-efficacy, and decisional balance for physical activity and dietary behavior.


RESULTS
The external validity of the trial was satisfactory with representative reach of workers and adoption of workplace units in the participating construction company. The extent to which the program was implemented as intended was modest. The intervention was effective on participants' progress through stages of behavior change.


CONCLUSIONS
Based on the RE-AIM dimensions, it is concluded that for construction workers, the program is feasible and potentially effective, but adjustments are required before widespread implementation.
