Adherence is a multidimensional phenomenon determined by the interplay of 5 sets of factors termed ‘dimensions’.

Patient-related factors are just 1 determinant. Health system, social-economic, treatment-related, and disease-related factors also affect people’s behavior and capacity to adhere to their treatment.
