The surrounding environment influences the constitution of illness perceptions. Therefore, local research is needed to examine how Libyan diabetes patients perceive diabetes and how their perceptions influence their medication adherence.


A cross-sectional study was conducted at the National Centre for Diabetes and Endocrinology in Tripoli, Libya, between October and December 2013. A total of 523 patients with type 2 diabetes participated in this study. A self-administered questionnaire was used for data collection; this included the Revised Illness Perception Questionnaire and the eight-item Morisky Medication Adherence Scale.


The respondents showed moderately high personal control and treatment control perceptions and a moderate consequences perception. They reported a high perception of diabetes timeline as chronic and a moderate perception of the diabetes course as unstable. The most commonly perceived cause of diabetes was Allah's will. The prevalence of low medication adherence was 36.1%. The identified significant predictors of low medication adherence were the low treatment control perception (p=0.044), high diabetes identity perception (p=0.008), being male (p=0.026), and employed (p=0.008).


Diabetes illness perceptions of type 2 diabetic Libyans play a role in guiding the medication adherence and could be considered in the development of medication adherence promotion plans.
