  1. Notes: Blank spaces correspond to variables that were not tested using formal mediation analyses. Times tested refers to the number of times a variable was analyzed; Effect, % refers to the number of times an effect was found and is expressed as percentage. Since mediation analyses were not conducted, results are organized according to the number of times each variable was tested in the overall analyses, depicted in the fifth column, in descent order. * ≥ 50% of these effects are based on correlational analyses. aTested twice in weak quality studies. bTested three times in weak quality studies. cTested in a weak quality study. [↑] means that higher value of (variable) was associated with improved outcomes; [↓] means "lower value of (variable)" was associated with improved outcomes.
