Part of the recruiting process for this study could have hindered the survey's external validity. The recruiting process included posting the survey to various esports related message boards, groups and communities on Reddit. Reddit is a platform where trolling tendencies are frequent and this could leave the survey at risk of internet trolls. Before posting, the researcher did not build any sort of rapport with the community or its leader, and it’s very possible that trolls could access the survey and skew the results for their own entertainment.
As far as internal validity goes, the construction of questions in the survey may have held back the generalization of the study’s results. The survey had 110 respondents that answered at least half of the questions in the survey, but there was data used in the results section that did not have responses for all 110 participants. This was either because a participant's prior answers pushed them past questions that did not pertain to them, or the respondent skipped the question altogether.
In future studies, researchers should secure more reliable ways to recruit subjects, or build a better rapport with these types of communities. In addition, researchers should make sure they do not allow for so many questions to be skipped, and have enough questions required to be answered to make sure they have all the data presented to them.
