Application of the information-motivation-behavioral skills model to improve medication adherence among older adults with type 2 diabetes: findings from a quasi-experimental study in Kermanshah, Iran.
Trial report in BMC geriatrics, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
introductionMedication adherence is crucial for effective blood sugar control in diabetes patients. However, older adults face a higher risk of non-adherence. This study aims to evaluate the effectiveness of a theory-based program designed to enhance medication adherence among older adults with type 2 diabetes.
methodsThis quasi-experimental study involved 100 elderly individuals with type 2 diabetes in Kermanshah, Iran, in 2024. Participants were randomly assigned to an intervention (50) or control group (50). The intervention group attended six 40-minute sessions over six weeks, based on the Information-Motivation-Behavioral Skills (IMB) model. Data were collected via a questionnaire assessing demographics, IMB model components, and medication adherence. Data were analyzed using SPSS version 16, employing chi-square tests and t-tests for comparisons, moreover, effect sizes were determined using Cohen's d.
resultsThe intervention group showed significant improvements, especially in "Information," with a very large effect size of 1.3 and an average change of 3.84 (p < 0.001). In contrast, the control group had minimal changes. Other components like "Attitude" and "Self-efficacy" also had large effect sizes (0.65 and 0.67). However, "Subjective Norms" showed a small effect size (0.11) with no significant changes. Additionally, the intervention group showed a significant improvement in medication adherence (effect size 1.15), increasing scores from 16.92 to 19.76, (p < 0.001) while the control group had minimal changes.
conclusionThe program based on the IMB model significantly improved medication adherence among elderly individuals with type 2 diabetes. We also identified the key theoretical methods of behavior change for each determinant of the IMB model and recommend utilizing them in the development of similar future interventions.
