  2. ° = For the main outcome variable the obtained Cronbach’s alpha of the scale at T0 is artificially low, probably due to the inclusion criterion of a CES total score of > 100, restricting the possible range of scores and items; °° Cronbach’s alphas might be low due to heterogeneity of the constructs and a low number of items (N = 3) for two subscale (CET 4, CET 5)
