Meaning of illness and quality of life in patients with type 2 diabetes

BackgroundInvestigations into personal factors influencing quality of life are important for those developing strategies to support patients with diabetes. This study aimed to investigate the influence of meaning of illness on quality of life in patients with type 2 diabetes.MethodsVeterans from primary care clinics in the southeastern United States completed a questionnaire including questions from the validated 5-scale Meaning of Illness Questionnaire (MIQ). Unadjusted and adjusted linear regression models investigated the physical and mental components of quality of life with the 5 MIQ factors.ResultsThe sample comprised 302 Black and White veterans. The physical component of quality of life (PCS) was positively associated with type of stress/attitude of harm (β = 2.43, CI: 0.94 to 3.93) and challenge/motivation/hope (β = 3.02, CI: 0.40 to 5.64) after adjustment, whereas the mental component of quality of life (MCS) was positively associated with the degree of stress/change in commitment (β = 2.58, CI: 0.78 to 4.38), and negatively associated with challenge/motivation/hope (β = − 2.55, CI: − 4.99 to − 0.11).ConclusionAttitudes of challenge, motivation and hope had opposite effects on mental and physical components of quality of life in this sample of veterans. Additionally, whereas, the type of stress and attitude towards harm or loss was associated with the physical component, the degree of stress and change in commitments was associated with the mental component. This suggests addressing the meaning of an illness may be complex but is an important consideration in improving both physical and mental components of quality of life in patients with type 2 diabetes.
