Translation, internal consistency, reliability and validity of the Thai version of Gout Assessment Questionnaire version 2.0 (GAQ 2.0).

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
objectivesTo translate the Gout Assessment Questionnaire version 2.0 (GAQ2.0) with Gout Impact (GI) Scale (GIS) into Thai and determine its psychometric property in gout patients with acute arthritis (acute arthritis group) and during the intercritical period (chronic gout group).
methodsTranslation followed the ISPOR recommendations. Cronbach's α, intraclass correlation coefficient (ICC) and standardized response mean (SRM) were used to determine internal consistency, reliability and responsiveness to change, respectively. Correlations between GI subscales with generic health-related quality of life (HRQoL) questionnaires (SF-36, HAQ-DI and EQ-5D-5L) and gout clinical parameters were determined.
resultsThe acute arthritis group and the chronic gout group comprised 27 and 92 patients, respectively. Internal consistency was sufficient for all GI subscales (Cronbach's α = 0.80-0.98), reliability was moderate to good in most GI subscales (ICC = 0.54-0.88) and responsiveness to change was moderate to large in most GI subscales (SRM = 0.43-0.98). The GI subscales correlated better with SF-36 than HAQ-DI and EQ-5D-5L. In the acute arthritis group, the unmet gout treatment needs subscale showed large and moderate negative correlation with tophi and serum uric acid, respectively. In the chronic gout group, the gout concern overall subscale had statistically significant, moderate correlation with overall gout severity rated by the patients and number of gout attacks over the past year, while the well-being during attack subscale and total GIS score had statistically significant, moderate correlation with overall gout severity rated by the patients.
conclusionThe Thai GAQ2.0 GIS showed acceptable internal consistency, reliability and responsiveness to change and correlated significantly with generic HRQoL questionnaires and clinical parameters. Key Points • The Thai GAQ2.0 GIS showed acceptable internal consistency, reliability and responsiveness to change in gout patients both during acute attack and during the intercritical period • The GI subscales showed significant correlation with SF-36 and HAQ questionnaires and gout clinical parameters in gout patients both during acute attack and during the intercritical period • The Thai GAQ2.0 GIS subscales should be used in conjunction with generic HRQoL for complete HRQoL assessment in gout patients.
