TABLE 2.

Explained variance of each measurement approach for different outcomes.

	Difference scores			RSA	Direct fit
	Squared	Absolute	Algebraic
Study satisfaction	0.064 (–)	0.058 (–)	0.037 (+)	0.142	0.251 (+)
Intent to leave	0.099 (+)	0.083 (+)	0.072 (–)	0.150	0.164 (–)
Grades	0.018 (+)	0.020 (+)	0.051 (–)	0.097	0.055 (–)

Columns show the explained variance in terms of R² (and adjusted R² for RSA) as well as the direction of the effect (in parentheses); (+) indicates a positive, (–) indicates a negative correlation with the respective outcome.
