Key result
The Ugandan version of the MMAS-8 demonstrated moderate internal consistency (Cronbach α = 0.65) and low test-retest reliability (weighted kappa = 0.36) for measuring antihypertensive medication adherence.

The translated MMAS-8 is a valid tool with moderate internal consistency for assessing antihypertensive medication adherence in Ugandan outpatients, revealing a high prevalence of low adherence.
Okello et al. (2016) conducted a cross-sectional in Hypertension (n=329). Translated Morisky Medication Adherence Scale (MMAS-U) was evaluated on Test-retest reliability (weighted kappa) (weighted kappa 0.36, 95% CI -0.01, 0.73, p=<0.001). The Ugandan version of the MMAS-8 demonstrated moderate internal consistency (Cronbach α = 0.65) and low test-retest reliability (weighted kappa = 0.36) for measuring antihypertensive medication adherence.
