To provide focus, in their overview of reviews, van Dulmen and colleagues have described theoretical approaches to adherence and categorized interventions on patient adherence for different medical conditions [ 17].
We felt that the opinions, attitudes and knowledge of patients regarding treatment, and a theoretical model of adherence behaviour could shape future interventions to promote adherence.
Regarding the second question, two ways exist to identify the theoretical perspectives underlying adherence interventions.
Effective interventions were found in each of four theoretical approaches to adherence interventions: technical, behavioural, educational and multi-faceted or complex interventions.
3. From a psychometric point of view, the linking of all of the evaluated factors will help establish an explanatory, integrative, theoretical model of adherence to healthy lifestyle rules recommended after GDM, therefore part of a broader research policy of prevention of type 2 diabetes.
To improve patients' adherence, our theoretical background was as follows.
They notice that as yet there is hardly a sound theoretical basis for explaining adherence behaviour.
Given the weak theoretical underpinning of many adherence interventions, a fruitful step might be to find the most promising theoretical mainstreams.
We will now look in more detail on the theoretical principles underlying the adherence interventions for which we found most evidence: technical, behavioural and educational interventions.
No one theoretical model underpinning exercise adherence was shown to be superior and the interventions that incorporated motivational strategies showed promise.
