Translation, cross-cultural adaptation, and psychometric evaluation of the Persian version of the Symptom Distress Scale (SDS) in heart failure patients.

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
backgroundPatients with heart failure experience severe and chronic physical and psychological manifestations while the disease progresses. Assessing the degree of distress caused by manifestations of the disease in patients is the first step in designing and evaluating intervention programs to improve patients' symptoms. The aim of this study was to investigate the psychometric properties of the Persian version of the Symptom Distress Scale in HF patients. MATERIALS AND
methodsThis study was conducted via methodological research design from March to November 2019. The translation process and cross-cultural adaptation were performed using a process recommended by the World Health Organization. The face and content validity and internal consistency were used to evaluate the validity and reliability of the instrument. The scale was evaluated by exploratory and confirmatory factor analysis in 300 patients with heart failure, and the obtained data were analyzed using SPSS-22 and AMOS-22 software.
resultsThe content validity of the scale was approved based on the results of the study. One-factor scale with 13 items was used in the confirmatory factor analysis, and the results showed that the instrument had high goodness-of-fit indices. Spearman correlation test for convergent validity showed a correlation between the score obtained by the Scale of Symptoms of Disease and the scores of The European Heart Failure Self-care Behavior scale (9 items) (
conclusionThe Persian version of the Symptom Distress Scale can be used as a valid instrument for people with heart failure due to its desirable psychometric properties.
