The Health Knowledge Inventory-Alpha: a personal health knowledge test for high school seniors.
This study assessed validity and reliability of the Health Knowledge Inventory-Alpha (HKI-Alpha) in a sample of high school seniors. The HKI-Alpha, a general health knowledge test, consists of 110 multiple choice items covering 11 health content areas. All seniors attending one of four high schools completed HKI-Alpha twice, one week apart. A secondary sample of college students also was tested. Descriptive analysis revealed the test discriminated among examinees and avoided ceiling and floor effects. Test-retest reliability was .81 (n = 355). Internal consistency reliability (KR20) was .85 (n = 418). A sample of college students scored significantly higher than the high school students, demonstrating construct validity. Other estimates of content validity, criterion-related validity, and construct validity were high.
