The Effectiveness of Social Cognitive Theory-based Interventions on Glycemic Control in Adults with Type 2 Diabetes Mellitus: A Systematic Review and Meta-Analysis Protocol
ABSTRACT
Background:
For those living with Type 2 Diabetes Mellitus (T2DM), failing to engage in self-management behaviors leads to poor glycemic control. Social cognitive theory (SCT) has been shown to improve health behavior by altering cognitive processes, increasing an individual’s belief in their ability to accomplish a task.
Objective:
The purpose of this review is to systematically identify, evaluate, and analyze the effect of SCT-based interventions to improve glycemic control in adults with T2DM.
Methods:
The research design and method of this systematic review and meta-analysis follow the 2009 Preferred Reporting Items for Systematic review and Meta-Analysis (PRISMA) reporting guidelines. Data sources include will include, but not limited to, PubMed, CINAHL, PsychINFO, Cochrane library, and Web of Science and will be reviewed with the use of customized text mining software. Included studies will focus on adults age 18 and older diagnosed with T2DM in randomized control trials located in the outpatient setting. Studies including Type 1 Diabetes Mellitus, gestational diabetes, prediabetes, drug-induced diabetes, metabolic syndrome, studies focused on healthcare professionals, and those younger than 18 will be excluded. All studies using SCT-based interventions along with studies that use a combination of SCT, and another theory, model, or framework will be included. Intervention effectiveness will be compared with routine care or standard care. Study quality and risk of bias will be appraised by three reviewers using Cochrane’s Risk of Bias Tool.
Results:
The results will be analyzed by the standardized mean differences which will be used to describe the intervention effect sizes on self-efficacy and diabetes knowledge. The raw mean difference of HbgA1c will be provided in a random effects model and presented in a forest plot.
Conclusions:
The conclusion of this systematic review and meta-analysis will appraise the effectiveness of SCT-based interventions for those diagnosed with T2DM and provide the most effective interventions for improving health behaviors in T2DM. Clinical Trial: This protocol is in editorial assessment with PROSPERO.
