Notes: Items with “G” labels referred to Importance Scale; items with “H” labels were the corresponding Use Scale items (How often assessment used in practice).
For EFA (Exploratory factor analysis) results, entries represent values from joint (two-factor) factor pattern matrix. For CFA (Confirmatory factor analysis), entries are estimated relationships for proposed two-factor model. Entries in bold represent values for the intended factor. EFA correlation between factors = .40; CFA correlation = .33.
