PMID 31406847WHAT IT FOUND
Among kidney transplant recipients, higher medication knowledge and higher perceived social support were linked to higher confidence in taking long-term medications.
The study did not show that teaching or support improves adherence.
Key findings
01In the analysed sample of 195 recipients, the mean long-term medication behaviour self-efficacy score was 125.75 on a 27 to 135 scale.
02Higher medication knowledge and higher perceived social support were positively correlated with self-efficacy; the total-score correlations were 0.352 and 0.232.
03Most recipients had high perceived social support, with 91.28% at high level and a mean total score of 69.77.

What it does not show
This was a single-centre cross-sectional survey, so it cannot show that knowledge or support causes higher self-efficacy. Participants were recruited by convenience sampling from follow-up clinics, and only 195 of 233 distributed questionnaires were analysed after 221 returns and 26 invalid forms. All recipients were Chinese-speaking adults at least 3 months post-transplant with a functioning graft, so results may not apply to other groups. Medication self-efficacy, social support and knowledge were self-reported, not observed or verified. The study did not explore other factors that may affect self-efficacy.

The easy way to misread this
Do not read the correlations as proof that improving medication knowledge or social support will increase self-efficacy or adherence. The study measured all variables at one time point and did not test any intervention.
