Table 2 Statistics and directions of the effects in the exploratory models for depression, anxiety, and burnout. Columns “direction” include information on whether increasing values of the predictor were linked to increasing ( >) or decreasing ( <) values of the dependent variables (questionnaire scores). Post-hoc comparisons with Holm correction were administered for “Years in Germany” in all models, but none of the contrasts survived the corrections.
