|Abstract: ||Background: The Questionnaire for Verifying Stroke-free Status (QVSFS) has been validated in Western populations
as a method for verifying stroke-free status in participants of clinical, epidemiological and genetic studies.
This instrument has not been validated in low-income settings where populations have limited knowledge of
stroke symptoms and literacy levels are low.
Objective: To simultaneously validate the 8-itemQVSFS in 3 languages spoken inWest Africa (Yoruba, Hausa and
Akan) for ascertainment of stroke-free status of control subjects in SIREN.
Methods: Using a cross-sectional study design, 100 participants each from the 3 linguistic groups will be consecutively
recruited fromneurology and generalmedicine clinics of 5 tertiary referral hospitals in Nigeria and Ghana.
Ascertainment of stroke statuswill be determined by neurologists using structured neurological examination, review
of case records and neuro-imaging (Gold standard). The relative performance of QVSFS without and with
pictures of stroke symptoms (pictograms) will be assessed using sensitivity, specificity, positive predictive
value (PPV) and negative predictive value (NPV).
Conclusion: The proposed study will provide valuable data on the performance of the QVSFS in resource-limited
