This case study…

…introduces an infrastructural framework to illustrate the feasibility of collecting social media data at scale. This is in the context of an ongoing multimodal sensing study of workplace performance

Facebook Data

slide-11
SLIDE 11

Out of 757 participants (Facebook data):

  • 587 participants consented and authorized
  • 67 consented, did not authorize
  • 103 did not have Facebook Account

We did not collect photos, media and private messages

Facebook Dataset: Participant Authorization

Who authorized Facebook Data?

u Female participants more likely

to authorize than Males

u Male participants less likely to

have a Facebook Account

u No significant difference in

authorization behavior across age, income, personality trait

Associating with Participant Attributes: Demographic

slide-15
SLIDE 15

Associating with Participant Attributes: Personality

uHigher agreeableness / extraversion / openness is

associated with greater likes and comments received

uHigher conscientiousness is associated with shorter

posts

uHigher neuroticism / openness is associated with

longer posts

slide-16
SLIDE 16

Associating with Participant Attributes: Wellbeing

uPoorer sleep quality is associated with longer posts,

more likes and more comments

uHigher negative affect is associated with lesser likes

received
