Abstract

This study examines the psychometric properties and tests the concurrent and predictive validity of a structured, self-reported medication adherence measure in patients with hypertension. The authors also assessed various psychosocial determinants of adherence, such as knowledge, social support, satisfaction with care, and complexity of the medical regimen. A total of 1367 patients participated in the study; mean age was 52.5 years, 40.8% were male, 76.5% were black, 50.8% graduated from high school, 26% were married, and 54.1% had income <$5,000. The 8-item medication adherence scale was reliable (alpha=.83) and significantly associated with blood pressure control (P<.05). Using a cutpoint of <6, the sensitivity of the measure to identify patients with poor blood pressure control was estimated to be 93%, and the specificity was 53%. The medication adherence measure proved to be reliable, with good concurrent and predictive validity in primarily low-income, minority patients with hypertension and might function as a screening tool in outpatient settings with other patient groups.

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

  • It is unclear whether the differences on the MMAS-8 are of clinical significance, because the scores would still meet the cut-off for low adherence.

    “however, it is unclear if the differences are of any clinical significance, as the scores on this measure would still meet the cut-off for 'low adherence'.”

    From Psychological interventions for improving adherence to inhaled therapies in people with cystic fibrosis (2023) · cites this paper as Morisky 2008

    The Results section defines MMAS-8 scores below 6 as low adherence, supporting the cited cut-off. The paper does not assess the particular score differences in the citing sentence or whether they are clinically significant; no page number is available in our copy. (LLM, conf=0.86)

    Experimental — accuracy not yet measured
  • There was a difference of 1.72 in favour of the intervention on the MMAS-8.

    “There was a difference of 1.72 in favour of the intervention on the MMAS-8 (Morisky 2008);”

    From Psychological interventions for improving adherence to inhaled therapies in people with cystic fibrosis (2023) · cites this paper as Morisky 2008

    The Methods section describes examination of the eight-item adherence measure, and the Results section reports its mean score and psychometric properties. Searches for “1.72” and an intervention-group difference found no passage reporting a 1.72-point MMAS-8 advantage for an intervention. (LLM, conf=0.75)

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.
