Abstract

OBJECTIVE To synthesize the measurement properties of six health-related quality of life instruments (Short Form 36 [SF-36], Short Form 12 [SF-12], EuroQol 5D-3L [EQ-5D-3L], EuroQol 5D-5L [EQ-5D-5L], Nottingham Health Profile (NHP), and Patient-Reported Outcome Measurement Information System Global Health [PROMIS-GH-10]) in patients with low back pain (LBP). STUDY DESIGN AND SETTING Six electronic databases (MEDLINE, EMBASE, CINAHL, PsycINFO, SportDiscus, and Google Scholar) were searched (July 2017). Studies assessing any measurement property in nonspecific LBP patients were included. Two reviewers independently screened the articles and assessed the risk of bias (COSMIN checklist). Consensus-based criteria were used to rate measurement properties results as sufficient, insufficient, or inconsistent; a modified GRADE approach was adopted for evidence synthesis. RESULTS High quality evidence was found for insufficient construct validity of SF-36 summary scores, and EQ-5D-3L utility and visual analogue scale scores. Moderate evidence was found for sufficient construct validity of SF-12 physical summary score and inconsistent responsiveness of EQ-5D-3L utility score. Very low quality evidence was found on each instrument's content validity; very low to low evidence underpinned the other assessed measurement properties. EQ-5D-5L, NHP and PROMIS Global Health-10 were not evaluated in LBP patients. CONCLUSION Documentation of the measurement properties of health-related quality of life instruments in LBP is incomplete. Future clinimetric studies should prioritize content validity.

TL;DR

This systematic review found that measurement properties of health-related quality of life instruments in low back pain are largely understudied, with very low quality evidence for content validity across six instruments. High-quality evidence indicated insufficient construct validity for SF-36 summary scores and EQ-5D-3L utility/VAS scores, while EQ-5D-5L, NHP, and PROMIS-GH-10 had little or no LBP-specific evaluation.

Key findings

  • From 4,809 records, 95 full texts were retrieved, 26 were eligible, and 9 more were found by citation tracking, yielding 35 included studies; 17 reported instrument development and 18 assessed other measurement properties.
  • High quality evidence showed insufficient construct validity for SF-36 physical and mental summary scores and for EQ-5D-3L utility and visual analogue scale scores.
  • Moderate evidence showed sufficient construct validity for the SF-12 physical summary score and inconsistent responsiveness for the EQ-5D-3L utility score; content validity for each instrument was supported by very low quality evidence.
  • The abstract reports EQ-5D-5L, NHP, and PROMIS-GH-10 were not evaluated in LBP patients; the results note one NHP construct validity study in which 37 of 48 hypotheses were met (77%), with low quality evidence.

Methods

  • Systematic review conducted according to COSMIN guidance and PRISMA, with a protocol registered in PROSPERO (CRD42015020021).
  • Six electronic databases (MEDLINE, EMBASE, CINAHL, PsycINFO, SportDiscus, Google Scholar) were searched in July 2017; studies were included if they assessed a measurement property in adults with nonspecific LBP or samples with at least 75% nonspecific LBP.
  • Two reviewers independently screened studies and assessed risk of bias with the COSMIN checklist; consensus-based criteria rated results as sufficient, insufficient, or inconsistent, and a modified GRADE approach rated quality of evidence.

Limitations

  • The paper states that evidence syntheses pooled studies from different cultures, countries, and languages, and that the search strategy targeted LBP rather than instrument development studies in generic populations.
  • The paper states that the reviewed instruments predate current COSMIN standards and that EQ-5D-5L and PROMIS-GH-10 were developed later, so fewer LBP studies exist for them.
  • Evident from the text: no included studies assessed cross-cultural validity for any instrument, and content validity evidence was very low and often based only on reviewers’ ratings because development studies lacked patient involvement and cognitive interviews.

About these checks

Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.

Claims read by deepseek-v4.1-flash under definition version 3 (extract-v3) on 2026-10-10.

Classified by jev-1.13-20260917 (gold-guideline-v0.2) on 2026-10-10.

Statistics and arithmetic are recomputed, not judged.

Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
