Outline
To develop a Knowledge, Attitude, and Behavior Scale for Adolescent Sexual and Reproductive Health and to conduct reliability and validity testing, providing a measurement tool for assessing adolescents’ knowledge, attitudes, and behaviors regarding sexual and reproductive health.
Based on the Knowledge, Attitude, and Behavior theoretical framework, an initial scale was formed through literature review, expert meetings, and preliminary surveys. A convenience cluster sampling method was employed to include 347 middle school students who met the criteria for item analysis and reliability and validity testing, resulting in the formal version of the scale.
The formal scale consists of three dimensions: knowledge, attitude, and behavior, with a total of 33 items. The expert authority coefficient score was 0.89, and Kendall’s W coefficient was 0.478. The content validity at the item level ranged from 0.82 to 1.00, while the content validity at the scale level was 0.93. Confirmatory factor analysis using Amos 24.0 yielded a model χ2/v of 1.831, RMSEA of 0.049, GFI of 0.842, CFI of 0.91,and PGFI of 0.739, indicating good model fit and structural validity. The overall Cronbach’s α was 0.914, with dimensionspecific Cronbach’s α values of 0.924, 0.767, and 0.741; the splithalf reliability of the total scale was 0.76. The testretest reliability correlation coefficient (r) for the total scale was 0.717 (P<0.001).
The Knowledge, Attitude, and Behavior Scale for Adolescent Sexual and Reproductive Health demonstrates good reliability and validity and can be used to assess adolescents’ knowledge, attitudes, and behaviors regarding sexual and reproductive health.
