Conscientiousness and medication adherence: A meta-analysis
Abstract
BACKGROUND: Approximately a quarter to a half of all people fail to take their medication regimen as prescribed (i.e. non-adherence). Conscientiousness, from the five-factor model of personality, has been positively linked to adherence to medications in several recent studies. PURPOSE: This study aimed to systematically estimate the strength and variability of this association across multiple published articles and to identify moderators of this relationship. METHOD: A literature search identified 16 studies (N = 3,476) that met the study eligibility criteria. Estimates of effect sizes (r) obtained in these studies were meta-analysed. RESULTS: Overall, a higher level of conscientiousness was associated with better medication adherence (r = 0.15; 95 % CI, 0.09, 0.21). Associations were significantly stronger in younger samples (r = 0.26, 95 % CI, 0.17, 0.34; k = 7). CONCLUSION: The small association between conscientiousness and medication adherence may have clinical significance in contexts where small differences in adherence result in clinically important effects.

Conscientiousness is associated with positive health-related behaviours.
“As researchers have noted, Conscientiousness is associated with positive health-related behaviours as it evinces a person's tendency to cohere with social norms and work toward objectives (Crescentini et al., 2018;Molloy et al., 2014).”

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.
