To evaluate the effect of Hip Hop Stroke, a school-based multimedia musical stroke literacy intervention that targets children aged 8-12 in high-risk minority communities, on the long-term learning of stroke knowledge.


We enrolled a cohort of 104 fifth and sixth grade children from 2 schools in Central Harlem into a single course of Hip Hop Stroke (3 1-hour classroom sessions, delivered over 3 consecutive days). Tests evaluating knowledge of stroke symptoms and behavioral intent to call 911 using hypothetical stroke scenarios were conducted at baseline, immediately after the intervention, and 15 months after the initial and only intervention. A composite score was created from 5 traditional stroke symptoms plus a distracter (chest pain). Data were analyzed using SAS version 9.2.


A total of 104 students completed both pretests (PTs) and immediate posttests (IPs), and 85 students completed all 3 tests, including a 15-month delayed posttest (DP) (81.7% retention rate). At pretest, 55.8% correctly identified calling 911. The baseline composite score was 3.24 (SD 1.45). At IP, stroke knowledge increased significantly across all items: calling 911 (85.6%, p < 0.001) and composite score (5.30, p < 0.0001). At 15 months, stroke knowledge increased significantly from PT for all measures except sudden headache with a composite score of 4.73 (p < 0.0001, PT vs DP).


Three hours of Hip Hop Stroke significantly improved knowledge of stroke symptoms and behavioral intent to call 911 of fifth and sixth grade children living in a high stroke risk neighborhood. This learning persisted for up to 15 months postintervention.
