Development and psychometric testing of four scales to measure perceptions and family influences on parental smoking in Taiwan

We developed and psychometrically tested four scales for measuring the perceptions of parental smokers and family members influences on smoking behavior in the presence of children in Taiwan. Data were collected from 309 parental smokers with school-aged children. The results of factor analysis revealed two to three factors within each scale, and the reliability was between 0.63 and 0.91, based on Cronbachs alpha. Our findings provide preliminary support for the reliability and validity of the scales. The collective application of the scales is comprehensive that may constitute a feasible approach for preventing parental smoking.
