^aOR = Odds Ratio (amount or increase in odds for decline with increasing values of the predictor); only if p ≤ 0.05 or for identified predictors in the logistic regression equation
^bSES = Socio Economic Status (calculated as mean of both parent's education and profession).
^cSBD = Social Burden of District (composite indicator calculated by the department of youth and family welfare of the City of Cologne) (very low, low, neither/nor, burden, strong burden); range in each sample '-2' to '2' dichotomized in: no or average SBD vs. moderate to high SBD
Ts = Teachers view in screening; Ps = Parents view in screening; int- = Internalizing-score; ext = Externalizing-score; tot = Total-score
* p ≤ 0.05; **p ≤ 0.01; significant (2-tailed) differences between participants and decliners at early steps of decision concerning project participation and indication for prevention,
- Unattainable
