Beliefs related to adherence to oral antidiabetic treatment according to the Theory of Planned Behavior

Abstract

OBJECTIVE: to identify salient behavioral, normative, control and self-efficacy beliefs related to the behavior of adherence to oral antidiabetic agents, using the Theory of Planned Behavior. METHOD: cross-sectional, exploratory study with 17 diabetic patients in chronic use of oral antidiabetic medication and in outpatient follow-up. Individual interviews were recorded, transcribed and content-analyzed using pre-established categories. RESULTS: behavioral beliefs concerning advantages and disadvantages of adhering to medication emerged, such as the possibility of avoiding complications from diabetes, preventing or delaying the use of insulin, and a perception of side effects. The children of patients and physicians are seen as important social references who influence medication adherence. The factors that facilitate adherence include access to free-of-cost medication and taking medications associated with temporal markers. On the other hand, a complex therapeutic regimen was considered a factor that hinders adherence. Understanding how to use medication and forgetfulness impact the perception of patients regarding their ability to adhere to oral antidiabetic agents. CONCLUSION: medication adherence is a complex behavior permeated by behavioral, normative, control and self-efficacy beliefs that should be taken into account when assessing determinants of behavior.

Oral health-related knowledge, attitudes and practices of adult patients in Mangaung Metropolitan Municipality, South Africa

“…Behavioural beliefs, normative beliefs and control beliefs were all associated with adherence to antidiabetic treatment in Brazil when salient beliefs regarding the treatment were analysed according to the TPB. 41 Positively strengthened intentions and actual behavioural control recorded in the results presented in the present study, influenced the planned performance of oral health-related behaviours and/or practices, as predicted by the TPB. A study in Belgium also found that the intentions of parents led to the performance of oral health-related behaviours.…”

Psychosocial determinants of adherence to oral antidiabetic medication among people with type 2 diabetes

“…The definition of the targeted behaviour was expressed as “ Taking the medications for the treatment of diabetes as prescribed by the physician, which means taking them every day, at the time and in the quantity indicated, remembering to be careful to take some before or after meals, fasting and/or when going to bed” ( Jannuzzi, Rodrigues, Cornélio, São‐João, & Gallani, ) . Then, participants were asked to answer the following question: “ In the last two months, I have taken the medications for treatment of diabetes exactly as prescribed by my physician,” on a four‐point Likert‐type scale: (a) rarely or never; (b) some days of the week; (c) most days of the week; and (d) every day or practically every day.…”
