Abstract
BackgroundQuality of life (QoL) is an important aspect of wellbeing for people with chronic conditions like type 2 diabetes, making it a noteworthy outcome. Knowledge about diabetes, attitudes, and self-management of diabetes are key factors that might directly or indirectly impact QoL. However, little is known about the inter-relationships between diabetes knowledge, attitudes, self-management and QoL among people with type 2 diabetes mellitus (T2DM). The aim of this study was to examine a model describing the relationship between diabetes knowledge, attitudes, self-management, and QoL of people with T2DM that is based on previous research linking pairs of these variables.MethodsA cross-sectional study design was employed in this research. A total of 291 participants, 192 males and 99 females, with T2DM, whose mean age was 55.8 (standard deviation = 11.09) completed questionnaires measuring diabetes knowledge (Diabetes Knowledge Scale), attitudes (Diabetes Integration Scale -19), self-management (Summary of Diabetes Self-care Activities Scale), including the aspects of diet, exercise, blood glucose testing, and foot care, and QoL (Diabetes Quality of Life Scale), comprising the aspects of satisfaction and impact on QoL respectively. To examine the model we proposed relating these variables, data were analysed using the path analysis.ResultsIn the final model, diabetes knowledge was a significant predictor for attitudes and self-management in terms of blood glucose testing. Attitudes was a significant predictor for self-management in terms of diet. In addition, self-management in terms of blood glucose testing was a significant predictor of impact of QoL, and self-management in terms of diet was a significant predictor of satisfaction and impact of QoL. Self-management in terms of exercise was a significant predictor of satisfaction in QoL. The final model reflected a good fit (χ2 (14) = 22.52, p = 0.069; CFI = 0.983; GFI = 0.983; RMSEA = 0.046).ConclusionsDiabetes knowledge, attitudes, and self-management are important factors that can impact the QoL among people with type 2 diabetes.
Highlights
Quality of life (QoL) is an important aspect of wellbeing for people with chronic conditions like type 2 diabetes, making it a noteworthy outcome
The present study provides valuable insight into the use of path analysis which is an extension of multiple regressions for testing the hypotheses in data related to diabetes knowledge, attitudes, self-management, and QoL among people with type 2 diabetes mellitus (T2DM)
There was no direct significant relationship between diabetes knowledge and QoL in the present study, we found that knowledge affected QoL indirectly through attitudes to living with diabetes and self-management in terms of blood glucose testing
Summary
Quality of life (QoL) is an important aspect of wellbeing for people with chronic conditions like type 2 diabetes, making it a noteworthy outcome. Little is known about the inter-relationships between diabetes knowledge, attitudes, self-management and QoL among people with type 2 diabetes mellitus (T2DM). The aim of this study was to examine a model describing the relationship between diabetes knowledge, attitudes, self-management, and QoL of people with T2DM that is based on previous research linking pairs of these variables. It is likely that people with diabetes will experience lower levels of quality of life (QoL) as the disease progresses. This will affect their motivation to maintain their health. Diabetes can lead to loss of personal income and productivity due to restrictions in the amount and type of work that people can perform, as well as early retirements due to diabetes-related complications [7,8,9]
