^aCME = continuing medical education; SM = social media; SMUPI = Social Media Use and Perception Instrument.

^bFactor 1 contains 5 items (1-5) representing the value of SM to CME course participants.

^cFactor 2 contains 4 items (6-9) representing the value of SM to CME course directors.

^dCronbach α reflects internal consistency reliability of items comprising each factor and overall (ie, all items combined).

^eThis item was eliminated from the statistical analyses because of ambiguous item loading.
