levels and reduce sedentary behavior within this growing population.
Currently, there is no gold standard to assess barriers to and motivators of physical
activity. However, in clinical practice the Barriers and Motivators Questionnaire is an
instrument that is used for the assessment of experienced barriers to and motivators of
physical activity.

e Barriers and Motivators Questionnaire was included in a more comprehensive cross-
sectional study that took place between June and August 2014 including all recipients of
solid organ transplantation (kidney, liver, lung, or heart) from the University Medical
Center Groningen, the Netherlands. Recipients must have received a transplant between
2002 and 2012, were of age 18 or older at the time of transplantation and capable of
transplantation or who had been re-transplanted after 2012 were excluded.
