1 · What the graph read from 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.

2 · The registry

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

purposeThis study validated the World Health Organization Quality of Life (WHOQOL-BREF) questionnaire with 3400 respondents living in Singapore.

methodsThe ethnic composition was 76.1% Chinese, 12.3% Malay, 9.6% Indian, and 2% Others. The sample included adults with disabilities (28.9%), adults recovering from mental health issues (14%), and adults from the general population (57.1%). Questionnaires about health-related conditions, the effects of disability on everyday functioning (WHODAS 2.0), the WHOQOL-BREF, and add-on modules of QOL of people with disabilities (WHOQOL-DIS) and QOL of elders (WHOQOL-OLD) were administrated.

resultsConfirmatory factor analysis supported a construct of QOL made of four domains, revealing good construct validity. The four domains predicted overall QOL and health satisfaction. Good internal consistency was evidenced by high alpha coefficients for the physical (.79), psychological (.82), social relationships (.81), and environment (.83) domains. Convergent validity was shown by moderate correlations between the different questionnaires measuring QOL (WHOQOL-BREF, WHOQOL-DIS, and WHOQOL-OLD), and discriminant validity by a lower correlation between the WHOQOL-BREF and disability. Convergent and divergent validity were also indicated by higher correlations between similar constructs across the different measures, and lower correlations between dissimilar constructs across measures, respectively. Concurrent validity was supported by showing that individuals with chronic medical conditions had lower QOL than individuals without chronic medical conditions.

conclusionsThe results showed that the WHOQOL-BREF has sound psychometric properties and can be used to measure QOL in Singapore.
