Schizophrenia Quality of Life Scale and Schizophrenia Quality of Life Scale Revision 4: A Systematic Review of Measurement Properties.
Synthesis in Schizophrenia bulletin, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 9 papers, 2 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.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
background and hypothesisSchizophrenia is a severe mental disorder that has a significant impact on quality of life (QOL). Measuring QOL can offer insights into treatment efficacy and areas of intervention, highlighting the importance of valid tools assessing QOL in people with schizophrenia. STUDY
designWe employed the COSMIN systematic review guideline to assess the psychometric properties of the schizophrenia quality of life scale (SQLS) and its 4th revision, the schizophrenia quality of life scale revision 4 (SQLS-R4), as patient-reported outcome measures (PROMs). STUDY
resultsThe search yielded 455 papers, 16 were included, 7 for the SQLS and 9 for the SQLS-R4. Both scales demonstrated good results in risk of bias assessment for internal consistency and convergent validity, the SQLS-R4 additionally for known-groups validity. For the SQLS, PROM development, structural validity, and reliability were suboptimal. The SQLS-R4 showed suboptimality regarding structural validity and reliability and inadequacy for cross-cultural validity and responsiveness. The updated criteria for good measurement properties indicated good convergent validity for the SQLS and good internal consistency, reliability, and convergent validity for the SQLS-R4. The SQLS showed suboptimal results for reliability and known-groups validity, while the SQLS-R4 demonstrated suboptimality in structural validity and known-groups validity. The SQLS had indeterminate structural validity and internal consistency; the SQLS-R4 showed indeterminate responsiveness, and insufficient cross-cultural validity. When using the updated GRADE approach of the COSMIN group, both scales received a very low grade.
conclusionsThe SQLS and SQLS-R4 hold the potential for recommendation in rating QOL. Identified weaknesses necessitate further validations.
