The year 2020 marks the 25th anniversary of the Psychosocial Aspects of Diabetes (PSAD) study group of the European Association for the Study of Diabetes. At the time, psychosocial diabetes research in Europe was steadily growing, but not well recognized. By establishing an official European Association for the Study of Diabetes study group, PSAD, for which purpose some hurdles had to be overcome, diabetes psychology became more visible and accessible to the scientific diabetes community. Over the years the PSAD study group has been successful in promoting the quality of research in the field through scientific meetings, mentoring, postgraduate education and publications. Looking back we can conclude that starting the PSAD study group signified an important moment in time, where researchers were joining forces to further the quality of the science, raise awareness of the importance of psychosocial aspects and promote the dissemination of psychological interventions in diabetes care.
