Table 5 Logistic regression analyses predicting a general interest to be involved in teaching undergraduates (vs. no interest) (2 models: one including and one excluding GPs already teaching undergraduates)

From: Willingness, concerns, incentives and acceptable remuneration regarding an involvement in teaching undergraduates - a cross-sectional questionnaire survey among German GPs

  Model 1
(including GPs already teaching undergraduates, N = 280)
(Nagelkerkes R2 = 0.471)
Model 2
(excluding GPs already teaching undergraduates, N = 225)
(Nagelkerkes R2 = 0.468)
Variables included in the model (stepwise forward LR) Odds Ratio OR (95% CI) p Odds Ratio OR (95% CI) p
Age groups (vs. <= 40 years)   <  0.001   <  0.001
41 to 50 years 0.57 (0.21–1.53) 0.266 0.67 (0.25–1.82) 0.436
51 to 60 years 0.33 (0.13–0.83) 0.018 0.35 (0.14–0.89) 0.028
> = 60 years 0.04 (0.01–0.15) <  0.001 0.03 (0.01–0.11) <  0.001
Any memberships in professional associations (vs. no membership) 1.97 (1.05–3.70) 0.035
“rather high” or “very high” self-perceived continuing education activities in comparison to colleagues (dichotomized, vs. “very low”/“rather low”/“average”) 3.42 (1.79–6.55) <  0.001 2.82 (1.41–5.65) 0.003
Wish to intensify continuing education activities: “rather yes”/“definitely yes”
(dichotomized, vs. “definitely not”/“rather not”)
1.95 (1.03–3.68) 0.040 2.00 (1.00–3.99) 0.049
Already has experiences with any kind of teaching activity (vs. not) 10.97 (5.35–22.49) <  0.001 11.28 (4.85–26.20) <  0.001
  1. Further variables considered: has children in the household currently (yes vs. no), has the permission to train residents (yes vs. no), a resident is working in the practice (yes vs. no), legal structure of the practice (single practice/joint practice/medical care center), practice environment (big city vs. small town/rural area), average effective work time per week (in hours)
  2. Variables not considered despite univariable differences: years since (first) medical specialist exam (reason: correlation with age r = .94), years until retirement (reason: correlation with age r = −.93), years having an own practice (reason: correlation with age r = .81)
