  • Times of the study was irregular

  • Participants who are adolescents may find it a struggle to complete as their family may be watching over them as they fill it out

  
  

• Evaluating the reliability and validity of data.

  • The data may not be reliable / may not come up with the same results due to the randomisation of the survey. Families in different municipalities may have different opinions regarding the attitude and behaviour of smoking.
