Development, translation, and validation of a bilingual questionnaire on unused medications in homes.

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
backgroundUnused medications in homes pose significant health, economic, and environmental risks. Patients are the medications end users and their knowledge, attitude, and practices (KAP) play an important role towards medication use, unuse and wastage. Thus, a valid instrument to reliably measure patients' KAP towards unused medications in homes may help manage the associated risks.
objectiveTo develop, translate, and validate a questionnaire for the assessment patients' KAP towards unused medications in Qatar homes (i.e., QUM-Qatar).
settingThis cross-sectional validation study was conducted among randomly selected outpatients visiting various public and private pharmacies in Qatar between September 2019 and February 2020.
methodNine experts in the field of pharmacy practice with Qatar contextual background established the content validity of the instrument. The validity was quantified using content validity index (CVI). Furthermore, construct validity was performed using principal component analysis (PCA), whereas internal consistency reliability of items was determined using Cronbach's alpha. Statistical analyses were performed using STATA 15 statistical software.
main outcome measureThe psychometric properties of the QUM-Qatar assessment instrument.
resultsAn English/Arabic questionnaire was developed and validated. Content validity in the form of scale-level-CVI (S-CVI)/Average and S-CVI/UA was 0.88 and 0.84, respectively, suggesting adequate relevant content of the questionnaire. Variation explained by the multivariate model was 85.0% for knowledge, 94.8% for attitude, and 89.8% for practice. Cronbach's alpha coefficients were 0.68, 0.82, and 0.84, for knowledge, attitude, and practice domains, respectively. From the psychometric results obtained, the questionnaire's validity and reliability were attained.
conclusionThe QUM-Qatar instrument has acceptable psychometric properties and has the potential for future use in research and practice to assess KAP towards unused medications in Qatar and elsewhere. It may consequently help in improving medication use and mitigating the negative health, economic, and environmental impacts of unused medications.Impacts on practice.•There is now a valid and reliable English/Arabic language questionnaire to assess patients' KAP towards unused medications.•Policymakers can utilize this questionnaire to develop evidence-based policies and strategies for managing unused medications and their disposal.•To improve medication use review, rational use of medicines, and adherence, it is necessary to consider patient-reported outcomes that may eventually reflect on saving health, economic resources, and environment.
