The short medication adherence scale (SMAS-7): Development and psychometric validation in a general population sample.

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
Background: Medication adherence is essential for treatment success across both chronic and acute conditions. However, concise, multidimensional, and broadly applicable validated tools to measure medication adherence remain scarce. Objectives: This study primarily aimed to develop and validate the Short Medication Adherence Scale (SMAS-7) and, secondarily, to assess adherence levels and related factors in a general adult population. Methods: A cross-sectional study was conducted among Lebanese adults aged ≥18 years from the general population. Individuals who declined follow-up contact for the test-retest phase were excluded. The 7-item SMAS-7, developed from the LMAS-14, was administered electronically in Arabic using an online questionnaire. Exploratory and confirmatory factor analyses (EFA and CFA) were performed on two random subsamples to assess factorial structure and model fit. Internal consistency (Cronbach's α, McDonald's ω), test-retest reliability (ICC), and construct and criterion validity were evaluated. Multivariable logistic regression identified predictors of adherence using a ROC curve-derived SMAS-7 cut-off score. Results: A total of 501 participants were included in the study. EFA revealed a 3-factor structure, psychological, economic, and behavioral domains, supported by KMO = 0.830 and significant Bartlett's test ( Conclusion: The SMAS-7 demonstrated strong preliminary psychometric properties in this initial validation study. It offers a valuable resource for researchers, clinicians, and policymakers seeking to monitor and enhance adherence behaviors. While these findings are encouraging, further studies in diverse populations and clinical settings are required to confirm its external validity and generalizability. The findings revealed suboptimal adherence and underscored the multifaceted nature of its predictors, highlighting the need for targeted, multidimensional interventions.
