Three modeling approaches were adopted in an effort to estimate an overall GFP in a CFA framework. The first general approach (Models 1 and 2) attempted to evaluate the GFP directly by modeling the scales from all instruments in hierarchical models. The second general approach (Models 3-5) conceptualized an intermediary factor structure involving ‘Alpha’, ‘Beta’, and in some cases ‘Gamma’ constructs for each instrument. The final general approach (Models 6 and 7) conceptualized these intermediary factors across instruments.
