           free-of-charge such as Depression Anxiety Stress Scale


           (DASS) have now become one of the most popular


           questionnaires for use widely throughout the world and

           until now (i.e. by the end of year 2019), it has already been


           cited more than 8000 times by the end of year 2021


           (Lovibond & Lovibond, 1995).

               In summary, there are several important considerations


           that should be considered when choosing the right


           questionnaire      to   be    validated.    Based     on    these

           considerations, it is therefore no surprise that the most


           suitable questionnaires to undergo validation will be the


           ones that are measuring important latent variables which

           also shall desirably exhibit evidence of excellent validity


           and reliability.
