Adaptation and evaluation of the measurement properties of the Brazilian version of the Self-efficacy for Appropriate Medication Adherence Scale

Abstract

Objectives:to undertake the cultural adaptation of, and to evaluate the measurement properties of, the Brazilian version of the Self-efficacy for Appropriate Medication Adherence Scale in coronary heart disease (CHD) patients, with outpatient monitoring at a teaching hospital. Method:the process of cultural adaptation was undertaken in accordance with the international literature. The data were obtained from 147 CHD patients, through the application of the sociodemographic/clinical characterization instrument, and of the Brazilian versions of the Morisky Self-Reported Measure of Medication Adherence Scale, the General Perceived Self-Efficacy Scale, and the Self-efficacy for Appropriate Medication Adherence Scale. Results:the Brazilian version of the Self-efficacy for Appropriate Medication Adherence Scale presented evidence of semantic-idiomatic, conceptual and cultural equivalencies, with high acceptability and practicality. The floor effect was evidenced for the total score and for the domains of the scale studied. The findings evidenced the measure's reliability. The domains of the Brazilian version of the Self-efficacy for Appropriate Medication Adherence Scale presented significant inverse correlations of moderate to strong magnitude between the scores of the Morisky scale, indicating convergent validity, although correlations with the measure of general self-efficacy were not evidenced. The validity of known groups was supported, as the scale discriminated between "adherents" and "non-adherents" to the medications, as well as to "sufficient dose" and "insufficient dose". Conclusion:the Brazilian version of the Self-efficacy for Appropriate Medication Adherence Scale presented evidence of reliability and validity in coronary heart disease outpatients.

Validation of an Arabic Version of the Self-Efficacy for Appropriate Medication Use Scale

“…The 13-item SEAMS is an effective and reliable self-report scale to measure self-efficacy for medication adherence that is useful in assessing poor or low self-efficacy for medication adherence among patients with chronic health conditions with limited health literacy [16]. It has been translated and validated into different languages, such as Portuguese [17], Taiwanese [28], Thai [29], and Chinese [30]. However, it does not exist in Arabic, which is the world's sixth most spoken language [31].…”

“…Scores range between 13 to 39, and the higher scores indicate higher self-efficacy for medication adherence [16]. It has been validated in other languages, such as the Portuguese; however, it has not been translated and validated into Arabic [17]. Thus, the primary objective of this study was to test the validity and reliability of a newly Arabic translated version of the 13-item SEAMS among patients with chronic diseases, such as diabetes and hypertension.…”

The Effectiveness of Educational Mobile Messages for Assisting in the Prevention of Early Childhood Caries: Protocol for a Randomized Controlled Trial

“…The secondary outcomes will be related to the measurement of the influence of educative strategies on parents or caregivers, considering their patterns of sugar consumption, their level of eHealth literacy, and their individual perceptions about their own ability in executing specific activities. These data will be collected at baseline and after the 12-month follow-up using the questionnaire for sugar consumption [26], the instruments eHEALS [23], and General Perceived Self-Efficacy Scale (GSES) [27], respectively. In addition, the results of eHEALS will be applied for the recruitment of participants.…”

“…It comprises 10 questions with answers arranged in a 4-point Likert scale, with options ranging from not at all true through exactly true . The total score ranges between 10 and 40 points, with greater scores indicating higher overall perceived self-efficacy of individuals [27].…”

Instruments to assess self‐efficacy among people with cardiovascular disease: A COSMIN systematic review

“…General self‐efficacy expresses the belief of a person in their ability to meet their difficulties, and self‐efficacy instruments particular to the disease include a more specific evaluation. As many instruments assessing general self‐efficacy and disease‐specific self‐efficacy, there are also behaviour‐specific self‐efficacy instruments on healthy eating, 28‐31 physical activity 22,32‐36 and medication adherence 37‐39 . For a complete assessment of the self‐efficacy, it is necessary to use different behaviour‐specific self‐efficacy instruments.…”
