The instrument was translated into Thai, and back-translation was conducted with comparison between original and back-translated items. Content validity was determined with the use of previously used items, expert review, and three sets of pilot tests. Confirmatory factor analysis (CFA) was conducted for construct validity, and the scales were confirmed. The number of items for INNO was too few to allow for CFA. Reliability was measured by Cronbach’s coefficient alpha, yielding moderately high coefficients, ranging from .78 to .81.
