About This Measure
About the Validation of this Measure
Country where validated:
Taiwan
Content validity:
Definitions of health literacy were reviewed to identify key domains for weight-specific health literacy. Consultation with a diverse expert panel led to the creation of a preliminary item pool, which was then subjected to a Delphi process to select the final items. These 17 items were subsequently pilot tested. After statistical analyses, 4 items were eliminated leading to a 13 item final version.
Criterion validity:
WSHLI was significantly correlated with short form Mandarin health Literacy Scale (y=0.71, p<0.001).
Reliability notes:
Factor 1: α=0.81 Factor 2: α=0.80
