The homogeneity or unidimensionality of items is a major issue in assessing the psychometric properties of an instrument. The Cronbach’s acoefficients for the ASNP total scale (0.90) and each of the three subscales (0.98–0.99) indicated good internal consistency for this newly constructed instrument. Overall, the results of test–retest analysis suggested that the ASNP and three of its subscales were relatively stable over a 2-week period
