What is adding persuasive elements?
In the design phase, persuasive elements should be added to the prototype to increase its effects. Examples of models that can be used to add persuasive elements are the Persuasive System Design (PSD) [1] and BCTs [2].
What is the aim of adding persuasive elements?
Persuasive technology is technology that is designed to change attitudes or behaviour [3]. To achieve this, persuasive elements should be added to the prototype during the design phase. Most eHealth technologies aim to influence specific behaviours or cognitions. Consequently, Behaviour Change Techniques (BCTs) can be added to the design as well, especially since research has shown that more extensive use of theory in technology results in increased effects [4]. BCTs are derived from behaviour change theories from psychology and can be defined as a general technique to influence or create changes in the predictors of specific behaviour.
