Abstract

RATIONALE AND OBJECTIVES: The scoring algorithm of the 12-item Short-Form Health Survey (SF-12) was revised in the second version (SF-12v2), but information on its psychometric properties is lacking. This study determined whether the SF-12v2 was a valid and equivalent substitute for the SF-36v2 Health Survey (version 2) for the Chinese. METHODS: A total of 2410 Chinese adults in Hong Kong completed the SF-36 Health Survey by telephone. The SF-12v2 data were extracted from the SF-36 data. Internal consistency was assessed by Cronbach's alpha, and test-retest reliabilities were evaluated by intraclass correlation. Criterion validity and equivalence were assessed using the SF-36v2 scores as a gold standard. Construct validity and sensitivity were assessed by known-group comparison. RESULTS: Internal consistency and test-retest reliabilities were good (range 0.67-0.82) for all except three scales. The SF-12v2 summary scores explained >80% of the total variances of the SF-36v2 summary scores. Construct validity and sensitivity were confirmed by significantly lower SF-12v2 scores in people with chronic diseases than those without. Effect size differences were less than 0.3 and relative validities were greater than 0.7 between SF-12v2 and SF-36v2 scores for different groups. CONCLUSION: The SF-12v2 was valid, reliable and sensitive for the Chinese. It is an equivalent substitute for the SF-36v2 for the summary scales.

Each is checked against this paper’s own text: does it say what the citing paper says it does?

  • Martinovic et al. reported both significant reduction of depressive symptoms and improved quality of life in adolescent patients receiving a CBT intervention, compared to a control group.

    “Martinovic et al. reported both significant reduction of depressive symptoms and improved quality of life in adolescent patients receiving a CBT intervention, compared to a control group [41]”
  • The finding of improvement in quality of life and work and social adjustment is concordant with existing evidence from controlled studies of CBT and ACT for epilepsy.

    “This finding is concordant with existing evidence from a small number of controlled studies of cognitive behavioural therapy and ACT for epilepsy.”

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.

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.
