trying to create a model of ISB looked at quality and understandability, distance/cost, relationship and affect, info need or task importance as mediating factors
determined source quality was the only thing driving whether people would approach them for info
survey method
constraints of the method
such a contained study of university workers at one university
self-selection of info sources; maybe they could have offered some choices
they were trying to propose a seeker-source info-need framework and then set out to get empirical backing for that model
how is source quality defined and measured?
factor analysis into 7 main constructs (began with ~20)
factor analysis looks for patterns of similar variance among sets of data; interesting that they didn't get underlying sources of variance
very typical use for factor analysis
then they used that data in a regression analysis
maybe diff kinds of measures?
