Validity and Reliability of a French Version of Reflux Symptom Index.
Assessing Laryngopharyngeal Reflux Symptoms with the Reflux Symptom Index
TLDR
Factor analysis of the Greek translation of the RSI demonstrated that it can be a reliable tool in the diagnostic approach of LPR patients and was able to discriminate 16 patients with LPR symptoms.
Assessment and Diagnostic Accuracy Evaluation of the Reflux Symptom Index (RSI) Scale: Psychometric Properties using Optimal Scaling Techniques
TLDR
It would be necessary to think about modifying the original RSI in order to improve its sensitivity and specificity (RSI binary version, adding or changing some items), or to introduce new scores in to better frame the probably affected of LPR patient.
Linguistic Adaptation, Reliability, and Validation of the Turkish Version of the Reflux Symptom Index.
The Validity and Reliability of the Reflux Finding Score.
Validity and Reliability of the Reflux Sign Assessment
TLDR
The RSA demonstrated high intra- and interrater reliabilities and responsiveness to change, and an RSA >14 may be suggestive of LPR.

Influence of Anxiety and Depression on the Predictive Value of the Reflux Symptom Index
TLDR
The presence of anxiety and depression impairs the predictive value of the RSI for LPR, which potentially explains some of the controversy over the diagnostic utility ofThe RSI.

Initial validation of a diagnostic questionnaire for gastroesophageal reflux disease
TLDR
A brief, simple 12-item questionnaire demonstrated validity and reliability and seemed to be responsive to change for reflux and dyspeptic symptoms and was highly predictive of the diagnosis of gastroesophageal reflux disease.

TLDR
LPR occurs in at least 50% of all patients at the center with laryngeal and voice disorders at presentation, and is found in patients with vocal cord neoplastic lesions and patients with muscle tension dysphonias.
Development of a Health-Related Quality-of-Life Questionnaire for Individuals with Gastroesophageal Reflux Disease (A Validation Study)
TLDR
The HRQoLquestionnaire was found to be reliable, valid, andresponsive, and known-groups validity was upheld, as patients who experienced more symptom days and patients who reported higher pain reported worse HRZoL than those with less symptoms or less severe pain.

Occult Laryngeal Pathology in a Community-Based Cohort
TLDR
Findings suggestive of laryngopharyngeal reflux are present in 64%, and vocal fold bowing is present in 72% of persons over 40, a community-based cohort of adults over 40.
The Validity and Reliability of the Reflux Finding Score (RFS)
TLDR
This work states that there is no validated instrument whose purpose is to document the physical findings and severity of laryngopharyngeal reflux (LPR).
The Otolaryngologic Manifestations of Gastroesophageal Reflux Disease (GERD): A Clinical Investigation of 225 Patients Using Ambulatory 24‐Hour pH Monitoring and an Experimental Investigation of the Role of Acid and Pepsin in the Development of Laryngeal Injury
TLDR
A new diagnostic technique is applied to a population of otolaryngology patients with GERD to determine the incidence of overt and occult GERD and the potential damaging effects of intermittent GER on the larynx are evaluated.
Effect of Gastric Acid on the Pathogenesis of Subglottic Stenosis
A case of subglottic stenosis, recalcitrant to conventional therapy, was associated with asymptomatic aspiration of gastric acid into the larynx. Once the reflux was controlled by use of an antacid
Laryngopharyngeal Reflux Symptoms Improve Before Changes in Physical Findings
TLDR
Patients with laryngopharyngeal reflux undergoing treatment appear to have improvement in symptoms before the complete resolution of the laryngeAL findings.
