Abstract

Background: The health-related quality of life (HRQoL) of people with aphasia (PWA) in Singapore is unknown.Aims: To compare outcomes between stroke survivors with and without aphasia in Singapore and examine the sensitivity and responsiveness to change of the Stroke and Aphasia QOL Scale (SAQOL-39g) and its Singapore (Mandarin) variant, SAQOL-CSg.Methods & Procedures: A longitudinal cohort study was conducted with stroke survivors with and without aphasia. Participants underwent a series of questionnaires at 3 and 12 months post-stroke including SAQOL-39g/SAQOL-CSg, Barthel Index, Modified Rankin Scale (MRS), Mini Mental State Examination, Frontal Assessment Battery, Center for Epidemiologic Studies Depression Scale and the EQ-5D. The following data analyses were conducted: comparison of stroke outcomes between participants with and without aphasia, computation of floor and ceiling effects, calculation of effect sizes (ESs) to determine sensitivity to change and estimation of minimally important differences (MIDs) for examining responsiveness.Outcomes & Results: A total of 78 participants (29.5% female, 29.5% PWA, mean age 64.1 years) completed all the assessments on both occasions. At 12 months post-stroke, PWA had higher levels of disability on the MRS (Mann–Whitney U = 294.5, p < 0.01) and reported significantly lower quality of life on the SAQOL-39g/SAQOL-CSg (U = 349, p < 0.01) and the EQ-5D index (U = 447, p < 0.05). In terms of sensitivity to change, the SAQOL-39g/SAQOL- 35CSg showed a small degree of improvement for the entire sample (ES, r = 0.22) but change was only significant for participants without aphasia. MID estimates for improvement were 0.21 on the SAQOL-39g/SAQOL-CSg and 0.17 on the EQ-5D index.Conclusions: PWA reported poorer HRQoL even when physical function was comparable. SAQOL-39g/SAQOL-CSg was found to have adequate sensitivity to change (i.e., reflect at least small change) up to 12 months post-stroke. MID estimates of the SAQOL-39g/SAQOL-CSg may assist in the interpretation of changes in scores in the clinical setting.

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

  • To achieve 80% power to detect an effect size of at least .50 with a random-effects model, outcome measures with cumulative within-group sample sizes below 100 or used in fewer than 10 studies were excluded.

    “To have a power of .80 to detect an effect size of ≥.50 using a random-effects model, outcome measures with cumulative sample sizes across within group studies < than 100 were excluded and/or if the measure was used in less than < 10 studies.25”

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.
