The new Stroke Action Test (STAT) effectively measures public knowledge of appropriate stroke responses, showing good reliability and validity for assessing critical, practical stroke symptom recognition and action. This tool aids in understanding public readiness for stroke emergencies.

Area of Science:

  • Neurology
  • Public Health
  • Health Education

Background:

  • Assessing public stroke response readiness is crucial.
  • Existing measures often rely on recall or recognition of stroke symptoms.
  • Current tools may not adequately assess practical application of stroke knowledge.

Purpose of the Study:

  • To develop and evaluate a novel written instrument for assessing public stroke response.
  • The instrument aims to link individual stroke symptoms with the most appropriate immediate action.
  • To enhance the accuracy of public readiness assessment for stroke events.

Main Methods:

  • Developed the Stroke Action Test (STAT) with 21 stroke symptom items and 7 non-stroke distractors.
  • Participants selected actions: call 911, call doctor, wait 1 hour, or wait 1 day for each item.

Related Experiment Videos

  • Validated the instrument with 249 community-based subjects, analyzing score reliability and validity.

    • Main Results:

    • The mean STAT score was 36.8%, indicating room for improvement in public stroke knowledge.
    • Participants correctly identified 'call 911' for only 34.1% of stroke symptoms.
    • The STAT demonstrated good reliability (alpha=0.83) and validity based on content and response analysis.

    Conclusions:

    • The STAT directly assesses practical stroke knowledge, an often-overlooked aspect of public preparedness.
    • The instrument provides reliable and valid scores for evaluating stroke response readiness.
    • Findings highlight the need for targeted public education on immediate stroke actions.
