[13] found that the global method had higher predictive validity of various behaviors including brand preference, product form preference, brand attitude, program choice and consumer satisfaction.

Early studies found EPQ - RSC to have high reliability and validity as a measure of personality traits in China.47 48 The total score for the extraversion subscale indicates introversion when it is less than 43.3, intermediate when it is from 43.3 to 56.7 «and extraversion when it is greater than 56.7.48 For the psychoticism subscale, tough - minded is defined as a total score greater than 56.7, intermediate is defined as a total score between 43.3 and 56.7 «and mild is defined as a total score less than 43.3.48 For the neuroticism subscale, a total score of less than 43.3 defines emotional stability, whereas a total score from 43.3 to 56.7 defines intermediate «and a total score greater than 56.7 defines emotional instability.48 For the lie subscale, a total score of 60 or greater indicates that information provided by the respondent might be unreliable.48 In this study, Cronbach's α for EPQ - RSC was 0.903.
