| Sumario: | A qualitative evaluation of 11 VDT users, who participated in a training program for the prevention of musculoskeletal and visual problems, investigated the extent of the application of the taught principles in everyday work. Data were collected over a 2 to 3 day period for each trainee, through an ergonomic work analysis in situ and semi-structured interviews, followed by recommendations, when appropriate, corresponding to the taught principles. A case analysis and a cross analysis of the data provided information about the developed ability for self-analysis of work regarding posture and visual comfort and what influenced it. A model depicting the process of transfer of knowledge and skills, from the training program to preventive action, was abstracted from data analysis. This model allows both the identification of problems in applying taught principles and the means to readjust the training program.
