Behavioural Change - Methods
Method 1: Population survey
With face-to-face interviews of a randomly
selected sample, the behavioural factors in the target population are surveyed.
Statistical analysis reveals the frequency and means of the factors (see figure below)
and with regression analysis the influence of the factors on behaviour
performance is determined. With these results the behavioural change techniques are
defined.

Method 2: Determining behavioural change techniques
Behavioral change techniques are well-known and widely tested in a vast amount of experiments in health or environmental psychology; examples are persuasion techniques, behavioral models, prompts, private and public commitment, goal setting, or feedback.
Additionally, these behavior change techniques are to be brought to
the people and applied with the help of dissemination techniques, like mass
media, loudspeaker cars, promoters, or person to person communication.
The selected techniques are tested in field experiments.

Method 3: Field testing of behavioural change techniques
In controlled field experiments, several techniques in
different combinations and sequences are tested in comparable areas in a
country. With the help of repeated panel and monitoring surveys, the different
effects of the techniques can be worked out. Computer simulations of human
conduct regarding the habitual use of the mitigation options are performed to
reveal changes in psychological factors over time and the resulting behavior
change. The goal is to show the effects of different dissemination and behavior
change strategies under existing cultural and social conditions.
