Qualitative research and content validity: developing best practices based on science and experience.
Article in Quality of life research : an international journal of quality of life aspects of treatment, care and rehabilitation, 2009. The graph could read no effect estimate from its abstract, so it casts no vote on the map. It is linked to trial NCT03567239 (Evaluating the Impact of Custom Assistive and Adaptive Technology), which is not on this map. Cited by 341 papers, 6 of them syntheses that pooled it.
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.

Abstract
purposeEstablishing content validity for both new and existing patient-reported outcome (PRO) measures is central to a scientifically sound instrument development process. Methodological and logistical issues present a challenge in regard to determining the best practices for establishing content validity.
methodsThis paper provides an overview of the current state of knowledge regarding qualitative research to establish content validity based on the scientific methodological literature and authors' experience.
resultsConceptual issues and frameworks for qualitative interview research, developing the interview discussion guide, reaching saturation, analysis of data, developing a theoretical model, item generation and cognitive debriefing are presented. Suggestions are offered for dealing with logistical issues regarding facilitator qualifications, ethics approval, sample recruitment, group logistics, taping and transcribing interviews, honoraria and documenting content validity.
conclusionsIt is hoped this paper will stimulate further discussion regarding best practices for establishing content validity so that, as the PRO field moves forward, qualitative research can be evaluated for quality and acceptability according to scientifically established principles.
