q2 i? Omega hierarchical indicated that only 62.2% of the reliable variance in total scores was due to general DL, while the general dimension and three specific dimensions were highly reliable. → Frank Reichert 2020

Reliability analysis of the bifactor model in Results (Table 6): general DL ω = .93, ωH = .58; "only 62.2% of the reliable variance in the total scores was due to general DL"; online information seeking was less reliably measured (ω = .59).

"The ratio of ω H to ω also shows that only 62.2% of the reliable variance in the total scores was due to general DL, aiding the interpretation of DL as a multidimensional (bifactor) construct."
