Note. CFI = .97, RMSEA = .15, SRMR = .06. All effects are unstandardized. 0 Fixed means variance/covariance was fixed to 0 in order to obtain proper estimates.
a
The ratio between model estimated true slope variance and observed variance in OLS estimated individual slopes (National Center on Response to Intervention, 2011).
b
The average variance extracted by slope, ρve (ηs) (Fornell & Larcker, 1981).
