• The study has a cultural bias: 


  sample was from one university in the USA. These students might come from a similar background which might affect the way they interact with Facebook. Results may not be generalizable to other universities in the USA or other countries. The sample consisted of journalism students who may have had an interest in Facebook.
• The study had an age bias


  the sample consisted of college students therefore results may not represent how Facebook use and depression correlated in people of a different age.
• Participants might have given socially desirable answers which would have affected the reliability of the study

  study used self-report measures people do not always respond to these honestly (they might have not been honest about how envious they felt of their peers on Facebook and may have given socially desirable answers instead) this could have biased the results.
• The results lack construct validity as complex phenomena was measured using simple number scales: 


  scores do not necessarily five the dull picture of participant’s depression or envy.
