Implications for rehabilitation
Organ transplant recipients are less active than the general population despite established health
bene

ts of physical activity.
A multidimensional structure is shown in the Barriers and Motivators Questionnaire, the use of the
identi

ed subscales increases applicability in research and clinical settings.

e use of the questionnaire with its component structure in the clinical practice of a rehabilitation
physician could result in a faster assessment of problem areas in daily practice and result in a higher
degree of clarity as opposed to the use of the individual items of the questionnaire.
