¹Extraction Method: Principal Component Analysis, Rotation Method: Varimax method
²Cronbach alpha was computed for each individual factor. For factors using a count method for deriving scores (formal interactions, informal interactions [Types 1 and 2], structural and electronic resources [Types 1, 2, and 3]), the recoded values were used to compute Cronbach alpha
* Dimensions derived based on count method
