Long-term behavior change as a result of a training intervention is difficult to achieve. The present study assumes that a training will have a stronger impact when (1) a theory-based intervention program is used (in this case based on Ajzen's [1991] Theory of Planned Behaviour), and (2) if a structured approach is applied (Intervention Mapping, Bartholomew et al., 2001). Using a supervised control (N = 19) - experimental (N = 35) group design, the present study showed that the TPB-model can be used to frame desirable behaviour and to measure the outcome of the intervention. IM appeared an effective method to influence behaviour in the desired way. During the whole intervention the intervention group showed significantly more improvement on the TPB variables (attitude, subjective norm, perceived behavior and intention) than the control group.
