aRecommended cutoff points for model fit indices [46-48]: SRMR of <0.08; RMSEA of <0.08; CFI of >0.90 (ideally CFI of ≥0.95); χ2/df of <3. Hu and Bentler [47] suggest a 2-index presentation strategy, recommending a RMSEA of 0.06 or lower and a SRMR of 0.09 or lower.

bRMSEA: root mean square error of approximation.

cCFI: comparative fit index.

dSRMR: standardized root mean residual.

e2-factor: active seeking and scanning channels.

f3-factor: searching, browsing, and scanning channels.
