Following a gluten-free diet is continually more common. Previous research has shown that following a gluten-free diet significantly affects the everyday life and quality of life of an individual. The aim of the research was to find out how following a gluten-free diet affects the everyday control and quality of life of an individual. The aim was also to find out how motivational aspects are linked to the following of the diet. The research results were to be viewed from the point of view of self-determination theory and theory of planned behaviour. The research aims to collect information that will help to understand the factors that affect the everyday life control and quality of life of those following the gluten-free diet. The research was carried out as a quantitative cross-sectional study. The data collected through Helsinki university E-form was comprised of answers to 55 questions. The questionnaire was completed by 356 persons. The data were analysed using IBM SPSS -statistics 23 and AMOS Graphics 24. The data were analysed using independent samples t-test, 2 independents samples tests, Kruskal–Wallis test, One-Way ANOVA, Jonckheere–Terpstra test, Principal components' analysis and confirmatory factor analysis. Spearman and Pearson correlation coefficients were also calculated. The gluten free diet affected the every day functions and social situations in many ways. Those with coeliac disease found following the diet easier than those with other dietary restrictions. The easiness of following the diet lessened avoidant behaviour, stress during lunch and the occurrence of negative feelings. The feeling of adequate support from social environment affected positively the quality of life and everyday life control of the subjects, and the feeling of adequate support from the inner circle was connected with precise following of the diet. Motivational factors were connected to several coping strategies and factors affecting the quality of life. Precise following of the diet didn't necessarily ensue the knowledge of the significance of the diet. This intention-behaviour gap reflected the subjects' lack of motivation.
